What is a Patent: Types, Procedure, and Example

Jun 13, 2025
Private Limited Company vs. Limited Liability Partnerships

In a world driven by innovation, protecting intellectual property is critical, not just for inventors but also for the advancement of science, technology, and industry as a whole. Patents are a powerful tool for safeguarding inventions, offering exclusive commercial rights, and encouraging investment in new ideas.

In this comprehensive guide, we’ll explore patents, the different types available, the filing process in India, what qualifies (and what doesn’t), and notable real-world examples.

Table of Contents

What is a Patent?

A patent is a legal right granted by a government authority to an inventor or assignee. It provides exclusive rights to make, use, sell, or license the invention for a fixed period, typically 20 years from the filing date (in the case of utility patents).

In India, patents are granted by the Indian Patent Office under the Indian Patent Act, 1970. Once granted, the patent gives the owner the legal authority to prevent others from commercially using the invention without consent.

In simple terms, a patent:

  • Protects original inventions
  • Offers a time-bound monopoly
  • Encourages innovation by offering a return on investment

Types of Patent

There are three main types of patents recognised globally (India primarily follows the utility patent framework):

1. Utility Patent

Covers new processes, machines, or compositions. These are the most common patents.
Example: A new smartphone battery technology.

Protection Duration: 20 years from the filing date.

2. Design Patent

Protects the unique visual appearance of an object, not its function.
Example: The contour design of a Coca-Cola bottle.

Protection Duration: 15 years (in countries where design patents are recognised separately).

3. Plant Patent

Covers new, asexually reproduced plant varieties.
Example: A genetically modified rose variety.

Protection Duration: 20 years (not commonly filed in India).

Types of Patent Applications

In India, there are four primary types of patent applications, each serving a distinct purpose:

1. Provisional Application

A temporary application filed to secure a priority date while the invention is still being finalised. It is valid for 12 months (must file a complete specification within this period).

2. Complete Application

It contains the full invention description, claims, and drawings. Can be filed directly or after a provisional application. It's the final and examinable document.

3. Divisional Application

It is filed when a single application contains multiple inventions. It allows the applicant to split them into separate applications while retaining the same priority date.

4. Additional Application

It is filed for improvements or modifications of an already filed invention. It must be linked to the main patent and cannot stand alone.

Importance of a Patent

Patents are more than just legal documents; they are strategic assets for innovation-driven businesses. Here’s why they matter:

  • Protects Innovation: Prevents unauthorised use or duplication of your invention.
  • Drives Research: Encourages R&D by granting exclusivity.
  • Public Disclosure: Adds to the pool of technical knowledge through public databases.
  • Market Advantage: Offers a monopoly that helps recover R&D investments.
  • Licensing Revenue: Can be monetised via licensing deals or sales.
  • Investor Confidence: Adds credibility and attracts funding.
  • Eligibility for Government Support: Many startup schemes and grants favour IP-holding firms.

What Can Be a Patent?

Under Indian law, an invention is patentable if it meets the following criteria:

  • Novelty: It must be new and not disclosed anywhere else.
  • Inventive Step: It must involve technical advancement or economic significance.
  • Industrial Applicability: It should be capable of being made or used in an industry.

Patentable Categories:

  1. Processes (e.g., water purification method)
  2. Machines (e.g., robotic arms)
  3. Articles of Manufacture (e.g., ergonomic chairs)
  4. Compositions of Matter (e.g., pharmaceutical formulations)
  5. Improvements on existing inventions (e.g., a faster version of a known algorithm)

What Cannot Be Patented?

Under Sections 3 and 4 of the Indian Patent Act, certain inventions are not patentable, even if they are novel.

Key Exclusions:

  • Frivolous or contrary to natural laws (e.g., perpetual motion machine)
  • Scientific theories or mathematical methods
  • Methods of agriculture or horticulture
  • Traditional knowledge (e.g., turmeric for healing wounds)
  • Medical treatments or surgical methods
  • Business methods or algorithms
  • Mental acts or abstract ideas
  • Atomic energy-related inventions (under Section 4)

These exclusions maintain ethical, cultural, and practical boundaries in IP law.

Patent Examples

Here are a few real-world patent examples that transformed industries:

  1. Wright Brothers' Airplane (1906):
    The first powered aircraft patent. Paved the way for modern aviation.
  2. Apple’s Slide-to-Unlock (2009):
    A design feature that defined smartphone interaction.
  3. Pfizer’s Lipitor (1993):
    A cholesterol-lowering drug that became one of the best-selling medications.
  4. Dyson Vacuum Cleaner (1986):
    Innovative cyclone technology with no loss of suction.

How Much Does a Patent Cost in India?

The total cost of obtaining a patent in India varies based on complexity, legal support, and the size of the entity. The cost includes:

  • Government Fees
  • Professional Charges
  • Examination Request Fee
  • Additional Costs: Translation, drawings, office actions, renewals

Patent protection lasts for 20 years, subject to annual renewal fees after grant.

Content of a Patent

A patent document includes several structured sections that describe and define the invention:

  1. Title of the Invention
  2. Bibliographic Details (applicant name, filing date, etc.)
  3. Background / Prior Art
  4. Detailed Description (technical specifications and working)
  5. Drawings or Diagrams
  6. Claims 

Unlike academic writing, patent specifications are precise, technical, and legal in tone. Many researchers prepare their own drafts, but expert assistance ensures compliance with formal requirements and claim strength.

Procedure for Getting a Patent in India

Here’s a step-by-step overview of the Indian patent filing process:

  1. Document the Invention: Maintain detailed records, diagrams, and experimental data.
  2. Conduct a Patent Search: To check if similar inventions exist.
  3. Draft a Provisional or Complete Specification.
  4. File the Application at the Indian Patent Office (offline or online).
  5. Publication: The application is published after 18 months unless early publication is requested.
  6. Request for Examination (RFE): Must be filed within 48 months.
  7. Examination Report & Objections: Respond to objections and make amendments, if needed.
  8. Grant of Patent: If approved, the patent is granted and published in the journal.
  9. Renewals: Pay annual renewal fees to maintain validity.

Difference Between Patents vs. Trademarks vs. Copyrights

Feature Patent Trademark Copyright
What it Protects Inventions (process, device, product) Brand identifiers (logos, names, symbols) Original creative works (books, music, art, software)
Duration 20 years 10 years (renewable indefinitely) Lifetime + 60 years
Example New engine technology Nike swoosh logo A novel or film script

Frequently Asked Questions

What do you mean by patent?

A patent is a legal right granted by a government to an inventor or assignee, giving them exclusive rights to make, use, sell, or license an invention for a limited period—typically 20 years from the date of filing. In exchange, the inventor must publicly disclose the details of the invention, contributing to scientific and technological knowledge.

What is a patent example?

Here are a few well-known examples of patented inventions:

  • Apple’s Slide-to-Unlock Feature (U.S. Patent No. 8,046,721): A widely recognised software patent that changed the way users interact with touchscreens.

  • Pfizer’s Patent for Lipitor (U.S. Patent No. 4,681,893): Protected the formula for a cholesterol-lowering drug that became a blockbuster medication.

Which Act governs the patent system in India?

The Indian patent system is governed by the Patents Act, 1970, along with the Patent Rules, 2003 (as amended). The Act defines what is patentable, outlines the procedure for filing and examination, and specifies the rights and obligations of patent holders.

The Controller General of Patents, Designs & Trade Marks (CGPDTM) oversees the administration and granting of patents through the Indian Patent Office.

Who can apply for a patent?

A patent application can be filed by:

  1. The true and first inventor (the person who actually created the invention)
  2. An assignee of the inventor (such as a company, research institution, or employer)
  3. A legal representative of a deceased inventor

In India, individuals, startups, small entities, educational institutions, and large companies can all apply for patents. Joint applications by multiple inventors or co-assignees are also permitted.

How to Convert a One Person Company (OPC) to LLP in India

How to Convert a One Person Company (OPC) to LLP in India

As India's entrepreneurial ecosystem evolves, founders now have access to a range of legal business structures tailored to different growth stages and ownership goals. From sole proprietorships and partnerships to private limited companies and, more recently, One Person Companies (OPCs) and Limited Liability Partnerships (LLPs) are among the most popular. 

While a One-Person Company (OPC) is ideal for solo entrepreneurs starting small, many founders later seek more flexibility, lower compliance, and shared ownership, making a Limited Liability Partnership (LLP) an attractive alternative.

If you’re planning to scale or bring in partners, converting your OPC to an LLP could be the right move. This blog walks you through the concept, legal framework, and procedure for converting an OPC to an LLP in India.

Table of Contents

Limited Liability Partnership (LLP)

An LLP is a hybrid business structure that combines the benefits of a company (limited liability) with the flexibility of a partnership. Some key features include:

  • Minimum two partners required
  • Liability of partners is limited to their contribution
  • No minimum capital requirement
  • Fewer compliance requirements than a company
  • Separate legal identity from its partners

One Person Company (OPC)

Introduced under the Companies Act, 2013, an OPC allows a single individual to operate a corporate entity. It offers:

  • Limited liability
  • Separate legal identity
  • Easier fundraising compared to a sole proprietorship
  • Greater credibility in business dealings

However, OPCs face limitations like:

  • Restrictions on fundraising
  • Mandatory conversion if turnover exceeds ₹2 crore or capital exceeds ₹50 lakh
  • Cannot have more than one member

Conversion of OPC to LLP

OPC conversion to LLP is governed by the Companies Act, 2013 and the Limited Liability Partnership Act, 2008. While direct provisions for OPC-to-LLP conversion are not explicitly provided, companies (including OPCs) can be converted into LLPs under Section 366 of the Companies Act and the Second Schedule of the LLP Act.

Understanding the Legal Provisions for Conversion of OPC to LLP

The legal path for converting an OPC to an LLP involves:

  • Section 366 of the Companies Act, 2013 (deals with companies being converted into LLPs)
  • Second Schedule of the LLP Act, 2008 (provides the procedure for such conversions)
  • Form FiLLiP and Form 18 under the LLP Rules, 2009

Note: Prior approval from the Registrar of Companies (ROC) is mandatory.

Eligibility Conditions and Compliance Steps for Conversion

To be eligible for conversion:

  • Before conversion, the OPC must have at least two shareholders (LLPs require a minimum of two partners).
  • No active defaults in filing annual returns, income tax, or other statutory dues.
  • All secured creditors (if any) must give their consent.
  • The company should not have applied for winding up or struck-off status.

Compliance steps include:

  1. Holding a Board Meeting and passing a resolution for conversion
  2. Increasing the number of members/directors to meet LLP requirements
  3. Obtaining name approval through RUN–LLP or FiLLiP form
  4. Filing Form FiLLiP and Form 18 with ROC
  5. Executing an LLP Agreement within 30 days of incorporation

Documents Furnished along with Form 18

Form 18 is the declaration for conversion and must be supported with:

  • Board resolution for conversion
  • Consent of all shareholders
  • Statement of assets and liabilities certified by a CA
  • List of creditors and their consent
  • Latest income tax return acknowledgement
  • Copy of PAN card and Aadhaar of all proposed partners
  • Address proof of the registered office of the LLP
  • NOC from the property owner (if rented office)

Procedure for Conversion of OPC to LLP

Here’s a step-by-step breakdown:

  1. Board Resolution: Approve the conversion plan and authorise directors to file the necessary forms.

  2. Increase Number of Members: Since an LLP requires at least two partners, the OPC must first induct another shareholder.

  3. DIN & DSC: Ensure all partners have a Director Identification Number (DIN) and Digital Signature Certificate (DSC).

  4. Name Approval: Apply for name reservation using RUN–LLP or through FiLLiP.

  5. Form FiLLiP Filing: File FiLLiP with ROC for incorporating the LLP.

  6. Attach Form 18: While filing FiLLiP, attach Form 18 with the required documents.

  7. Certificate of Incorporation: On approval, the ROC will issue a Certificate of Incorporation for the LLP.

  8. Execute LLP Agreement: Draft and file the LLP Agreement within 30 days.

  9. Apply for PAN, TAN & GST: Update statutory registrations with new LLP details.

  10. Close OPC Bank Account & Update Records: Close existing bank accounts of OPC and update stakeholders.

Frequently Asked Questions

Why convert an OPC into an LLP?

Converting to an LLP offers greater flexibility, allows multiple partners, reduces compliance burden, and enables easier capital infusion, making it suitable for scaling beyond a single founder.

Is it mandatory to get creditor consent for conversion?

Yes. Obtaining written consent from creditors is required, as their rights could be affected during the conversion process.

Can an OPC with outstanding debts be converted into an LLP?

Yes, but all creditors must be informed, and their no-objection certificates (NOCs) must be secured. The LLP will assume all debts and liabilities of the OPC post-conversion.

Will the new LLP retain the OPC’s assets and liabilities?

Yes. Upon conversion, all assets, liabilities, obligations, and agreements of the OPC automatically vest in the LLP.

Do tax implications arise during conversion?

If the conversion meets certain conditions under the Income Tax Act (e.g., continuity of business and ownership), it can be tax-neutral. Otherwise, capital gains tax or other liabilities may apply. It’s advisable to consult a tax expert.

Proprietorship Tax Return Filing Procedure and Its Compliance

Proprietorship Tax Return Filing Procedure and Its Compliance

A sole proprietorship is the simplest form of business ownership in India. It is not considered a separate legal entity from its owner, which means the business income is treated as the personal income of the proprietor.

As such, tax compliance and return filing are governed by the Income Tax Act for individuals. Filing income tax returns (ITR) is not only a legal requirement but also essential for accessing financial benefits like business loans and expansion opportunities, as well as maintaining a credible financial history.

In this blog, we’ll break down the tax return filing procedure for proprietors, explain key compliances, and highlight the benefits of timely filing.

Table of Contents

Overview of Taxation for Proprietorships in India

In India, proprietorships are taxed as individual taxpayers under the Income Tax Act. The business income is added to the proprietor's total income and taxed according to the applicable individual tax slabs. Proprietors typically file their income tax returns using:

  • ITR-3: For individuals and HUFs having income from a proprietary business or profession
  • ITR-4 (Sugam): For those opting for the presumptive taxation scheme under sections 44AD, 44ADA, or 44AE

Taxpayers can choose between the old tax regime (with deductions and exemptions) or the new one (with lower tax rates but no exemptions).

Do Proprietorship Firms Need to File Income Tax Returns?

Yes, proprietors are legally obligated to file ITRs if their total income exceeds the basic exemption limit, which for FY 2024-25 is:

  • ₹2.5 lakh for individuals below 60 years
  • ₹3 lakh for senior citizens (60-80 years)
  • ₹3.5 lakh for super senior citizens (above 80 years)

Even if the income is below the exemption limit, filing returns is necessary to carry forward business losses, to claim TDS refunds and if there are any foreign assets or income involved.

Importance of Filing Income Tax Returns for Proprietorship Firms

Beyond legal compliance, filing ITR offers several advantages:

  • Financial Credibility: Enhances your chances of securing loans, credit lines, or business investments
  • Business Growth: Essential for bidding in tenders and expanding operations
  • Avoiding Penalties: Non-filing attracts penalties and interest under the Income Tax Act
  • Refund Claims: Enables claiming refunds on excess TDS deducted

{{company-reg-cta}}

Tax Audit for Proprietorship

A tax audit is a review of accounts to ensure accuracy and compliance with tax laws. For proprietorships, audit requirements apply if:

  • Turnover exceeds ₹1 crore (business)
  • Gross receipts exceed ₹50 lakh (profession)
  • Turnover exceeds ₹10 crore if 95% of payments and receipts are digital

Non-compliance with tax audit provisions can attract a penalty under Section 271B, which can be up to 0.5% of turnover or a maximum of ₹1.5 lakh.

Presumptive Taxation Scheme: A Simplified Option for Small Proprietors

To ease compliance for small taxpayers, the Income Tax Act offers presumptive taxation schemes:

  • Section 44AD: For small businesses with turnover up to ₹2 crore (to be extended to ₹3 crore from AY 2025-26 if cash transactions are below 5%)
  • Section 44ADA: For professionals with receipts up to ₹50 lakh
  • Section 44AE: For those involved in the business of transportation

ITR Guidelines for Proprietorship Firms – Union Budget 2024–25 Insights

The Union Budget 2024 brought several important changes aimed at easing compliance, promoting transparency, and offering relief to taxpayers, especially for salaried individuals and businesses.

Here's a quick overview of key updates relevant to individual taxpayers and proprietorships:

1. Increased Standard Deduction Under the New Tax Regime

To offer more relief to salaried individuals, the standard deduction under the new tax regime has been increased from ₹50,000 to ₹75,000.

2. Reduced TDS Rates on Specified Payments

The budget has also reduced the Tax Deducted at Source (TDS) rates on certain specified payments to improve ease of doing business and simplify compliance for both payers and recipients. This change will benefit small and mid-sized businesses by easing their cash flow and lowering the burden of upfront tax deduction.

3. Government Scheme for First-Time Entrepreneurs

The Union Budget 2024 introduced a new loan scheme to support first-time entrepreneurs. The scheme aims to promote inclusive entrepreneurship and boost India’s startup ecosystem.

Frequently Asked Questions

What is proprietorship compliance?

Proprietorship compliance refers to the set of legal, financial, and tax-related requirements that a sole proprietorship must fulfil. This includes:

  • Income tax return (ITR) filing
  • GST registration and returns (if applicable)
  • Tax audit (if turnover crosses prescribed limits)
  • Maintenance of books of accounts
  • Maintenance of books of accounts
  • TDS deductions and filings (if applicable)
    Business licenses like FSSAI, trade license, etc., depending on the nature of the business

Since a proprietorship is not a separate legal entity, all compliances are fulfilled in the name of the individual (proprietor).

Which ITR is applicable for a proprietorship firm?

The applicable ITR forms for proprietorship firms are:

  • ITR-3: For proprietors who maintain books of accounts and have regular business or professional income.
  • ITR-4: For proprietors who opt for the Presumptive Taxation Scheme under Section 44AD, 44ADA, or 44AE.

Note: ITR-4 is only applicable if your turnover is within the prescribed limit (currently ₹3 crore for businesses opting for digital payments).

What are the requirements for a tax audit for a proprietorship?

A tax audit under Section 44AB is mandatory for a proprietorship if:

  • Turnover exceeds ₹1 crore (for business) in a financial year
  • Turnover exceeds ₹10 crore for businesses where 95% of payments and receipts are digital

Also, if a proprietor opts out of the presumptive taxation scheme after opting in (under 44AD/44ADA), a tax audit becomes applicable for the next five years, regardless of turnover.

What is the turnover limit for a proprietorship?

There is no fixed turnover limit to run a proprietorship, but there can be certain turnover limits for tax compliance purposes.

Is GST required for a sole proprietorship?

GST registration is mandatory for a sole proprietorship if:

  • Turnover exceeds ₹40 lakh (for goods) or ₹20 lakh (for services) in most states
  • You are involved in the interstate supply of goods
  • You sell on e-commerce platforms (like Amazon, Flipkart)

Form ADT-1: A Complete Guide to Auditor Appointment Filing

Form ADT-1: A Complete Guide to Auditor Appointment Filing

Filing Form ADT-1 is a crucial step in ensuring compliance with the Companies Act regarding the appointment of the first auditor. This form notifies the Ministry of Corporate Affairs (MCA) about the auditor's appointment within 30 days of company incorporation. It is essential for companies to understand the importance of this form and adhere to the filing requirements and deadlines to avoid penalties.

Table of Contents

What is Form ADT-1?

Form ADT-1 is a mandatory filing under the Companies Act, 2013, used to inform the Registrar of Companies (ROC) about the appointment of an auditor in a company.

Key Points on Auditor Appointment & Filing Requirements

1. Appointment of First Auditor (New Companies)

For companies (excluding government companies):

The Board of Directors must appoint the first auditor within 30 days of incorporation.

If the Board fails to do so, the members must appoint the first auditor within 90 days at an Extraordinary General Meeting (EGM).

The first auditor holds office until the conclusion of the first Annual General Meeting (AGM).

Note: Filing Form ADT-1 is NOT required for the first auditor’s appointment. However, companies may choose to file it for compliance and record-keeping purposes.

2. Appointment of Subsequent Auditors

After the first AGM, companies must appoint an auditor for a five-year term (for private and public companies) or as per shareholder approval.

Form ADT-1 must be filed within 15 days of the auditor’s appointment to inform the ROC.

Timely filing of Form ADT-1 is crucial for companies to:

  • Comply with legal requirements under the Companies Act
  • Avoid penalties and legal consequences
  • Maintain transparency in auditor appointments
  • Ensure proper oversight of financial reporting

Who Needs to File Form ADT-1?

Is Form ADT-1 mandatory for all companies?

All companies incorporated under the Companies Act, 2013, are required to file Form ADT-1, including:

What happens if a company fails to file Form ADT-1?

Failure to file Form ADT-1 within the prescribed time can result in penalties and legal consequences for the company and its directors. The company may be fined between ₹25,000 to ₹5,00,000, and every defaulting officer may be punishable with imprisonment of up to 1 year, a fine between ₹10,000 to ₹1,00,000, or both.

Law Governing the Form ADT-1

The filing of Form ADT-1 is mandated under Section 139(1) of the Companies Act, 2013. This section requires companies to file the form with the ROC to inform them about the auditor's appointment, which is done after the AGM. The form contains essential details about the appointed auditor, such as their name, address, membership number, and date of appointment. Companies must submit Form ADT-1 within 15 days of the AGM to fulfil their legal obligations and avoid potential penalties for non-compliance.

Requirements for Filing Form ADT-1

  • The company has appointed an auditor as per the provisions of the Companies Act, 2013
  • The appointed auditor has provided written consent to act as the auditor
  • The auditor has issued a certificate confirming they are not disqualified under Section 141 of the Act
  • The company has obtained a Director Identification Number (DIN) for the signing director
  • The signatory has a valid Digital Signature Certificate (DSC)

Companies must attach the necessary supporting documents, such as the board resolution for auditor appointment, auditor's consent letter, and certificate of eligibility while filing the form. Failing to meet these requirements can lead to the rejection of the form by the ROC.

Fees for Filing Form ADT-1

The filing fees for Form ADT-1 depend on the company's authorised share capital, as per the table below:

Authorised Share Capital Filing Fee
Up to ₹1,00,000 ₹200
₹1,00,001 to ₹5,00,000 ₹300
₹5,00,001 to ₹10,00,000 ₹400
Above ₹10,00,000 ₹600

For LLP Companies without share capital, the filing fee is a flat ₹200.

Late filing of Form ADT-1 attracts additional fees, which increase based on the delay duration:

  • Up to 30 days delay: 2 times the normal fees
  • 31 to 60 days delay: 4 times the normal fees
  • 61 to 90 days delay: 6 times the normal fees
  • 91 to 180 days delay: 10 times the normal fees
  • More than 180 days delay: 12 times the normal fees

Due Date For Filing MCA Form ADT-1

The due date for filing Form ADT-1 depends on whether the company is newly incorporated or existing:

For newly incorporated companies:

  • ADT-1 for the first auditor must be filed within 15 days of the first Board Meeting
  • This Board Meeting must be held within 30 days of incorporation, where the first auditor is appointed

For existing companies:

  • Form ADT-1 should be filed within 15 days of the AGM where the auditor was appointed or reappointed
  • Example: If the AGM was held on September 30, 2023, the ADT-1 due date would be October 14, 2023

While filing the form, companies must provide the following details about the appointed auditor:

  1. Auditor's category (individual or firm)
  2. Membership number of the auditor or firm's registration number
  3. Address and email ID of the auditor
  4. Permanent Account Number (PAN) of the auditor
  5. Period of appointment
  6. Membership number of the previous auditor in case of vacancy
  7. Date of appointment and AGM date
  8. Details of any casual vacancy (date and reason)

Along with these details, companies must attach the following supporting documents:

  1. Certified copy of the Board Resolution for auditor appointment
  2. Written consent of the auditor to act as such
  3. Certificate by the auditor confirming their eligibility under Section 141
  4. Copy of the intimation letter sent by the company to the auditor regarding their appointment

Penalty on Delayed Filing of Form ADT-1

Delayed filing of Form ADT-1 attracts penalties, which increase based on the duration of the delay:

  • Up to 30 days delay: Twice the normal filing fees
  • 31 to 60 days delay: Four times the normal filing fees
  • 61 to 90 days delay: Six times the normal filing fees
  • 91 to 180 days delay: Ten times the normal filing fees
  • More than 180 days delay: Twelve times the normal filing fees

Companies must be mindful of the ADT-1 due date and ensure timely filing to avoid these escalating penalty fees. Repeated non-compliance can also lead to more severe consequences, such as fines and legal action against the company and its officers.

Important Points to Consider Regarding Form ADT-1

  • Filing Form ADT-1 is mandatory for all types of companies, including private, public, and one-person companies.
  • The responsibility of filing the form lies with the company and its directors, not the auditor.
  • Form ADT-1 must be filed even in case of filling casual vacancies in the auditor's office.
  • Companies should file Form ADT-1 for the appointment of the first auditor as well.
  • Timely filing of the form with all necessary details and documents is crucial to avoid penalties and legal complications.

Process for Filing Form ADT-1

  1. Obtain a Digital Signature Certificate (DSC) for at least one Director of the company from a licensed Certifying Authority
  2. Ensure the signing director has a valid Director Identification Number (DIN)
  3. Download Form ADT-1 from the MCA portal
  4. Fill in the required company and auditor details accurately
  5. Attach the necessary supporting documents (Board Resolution, auditor consent, eligibility certificate, etc.)
  6. Verify the form using the director's DSC
  7. Submit the form electronically on the MCA portal
  8. Pay the requisite filing fees online using a credit card, debit card, or net banking
  9. Receive an acknowledgement email from MCA as proof of filing
