How to Start a Tax Consultancy Business in India

A tax consultancy assists individuals, firms and companies with tax compliance, return preparation, registrations, tax planning and responses to tax notices. Starting a practice requires suitable expertise, an appropriate business structure, reliable systems and careful observance of rules governing professional representation.

Important: Tax return preparation and general compliance support are not the same as statutory audit, certification, legal practice or unrestricted representation before tax authorities. These regulated activities must be undertaken only by persons authorized under the relevant law. Requirements and rates can change; check the linked official portals before acting.

Tax consultancy services

Depending on professional authorization and the client's needs, a consultancy may provide the following services:

Preparation and electronic filing of income-tax returns, computation of taxable income and lawful tax planning.
PAN (Permanent Account Number) and TAN (Tax Deduction and Collection Account Number) application assistance.
Tax Deducted at Source (TDS) and Tax Collected at Source (TCS) calculations, deposits, statements, corrections and reconciliations.
Goods and Services Tax (GST) registration, return preparation, invoice compliance and reconciliation.
Advice on business formation, transactions, purchase or sale of a business and associated tax implications.
Accounting support, financial reporting and maintenance of tax records.
Assistance with notices, assessments, appeals and authorized representation, subject to statutory eligibility.
Legacy VAT, Central Sales Tax and service-tax matters where old-period disputes or returns remain relevant, and state VAT matters for goods still outside GST where applicable.

Most supplies formerly subject to service tax or state VAT are now covered by GST. These legacy taxes should not be advertised as ordinary new registrations for GST-covered services.

Who can start a tax consultancy?

A person with suitable knowledge may offer permitted tax preparation and administrative support. However, the right to carry out reserved professional functions depends on the applicable statute, not merely on operating a consultancy.

Income-tax representation

Section 288 of the Income-tax Act, 1961 governs representation through an authorized representative for proceedings to which that provision applies. It recognizes specified categories, subject to qualifications, restrictions and disqualifications. A consultant should check the law applicable to the relevant tax year and proceeding, including the transition to the Income-tax Act, 2025 from 1 April 2026. See the Income Tax Department and India Code.

GST representation

Section 116 of the Central Goods and Services Tax Act, 2017 specifies who may appear as an authorized representative in proceedings under that Act, with statutory exclusions. Section 48 provides for the authorization and regulation of GST practitioners. A GST practitioner must satisfy the relevant rules and enrolment requirements; enrolment does not itself confer all rights of an advocate or chartered accountant. Refer to the GST portal and CBIC GST resources.

Audit and other regulated work

Tax audits and attestations reserved for chartered accountants must be carried out by appropriately qualified and authorized practitioners. Advocates and other regulated professionals must comply with their own governing statutes and professional rules. For chartered accountancy requirements, consult the Institute of Chartered Accountants of India.

Starting as a sole proprietorship

A sole proprietorship is a business operated by one individual and is not a separate legal person. It can be a practical starting point for a small consultancy, provided the proprietor is eligible to perform each proposed service.

Office and facilities

A home office, owned premises, coworking space or rented office may be suitable, subject to local regulations, client confidentiality and professional rules. Basic facilities include computers, secure internet, printer or scanner, licensed accounting and tax software, secure document storage, business email and backup systems. Telephone and fax facilities may be added where clients require them.

Staff

At first, the proprietor may handle most assignments. As work increases, clerical or bookkeeping staff, a receptionist, document-processing assistants and general support staff may be engaged. Qualified professionals should supervise work that requires professional judgment or certification.

Bank account

Bank documentation typically includes the proprietor's PAN, identity and address evidence, photographs or digital KYC, and proof of business activity or address as required by the bank. The Reserve Bank of India KYC directions and the bank's policies govern acceptable documents; a bill issued by the firm is not universally sufficient.

Starting as a partnership or LLP

Two or more eligible persons may consider a partnership or a limited liability partnership (LLP), subject to restrictions applicable to their profession. A written agreement should define capital contributions, profit sharing, management, responsibilities, admission and retirement of partners, confidentiality and dispute resolution.

Partnership deed and registration

The Indian Partnership Act, 1932 governs ordinary partnerships. Registration of an ordinary partnership is generally not compulsory, but Section 69 restricts certain suits to enforce contractual rights by or on behalf of an unregistered firm, subject to statutory exceptions. The deed should be appropriately stamped under applicable state law. Consult India Code and the relevant state Registrar of Firms.

Limited liability partnership

An LLP is a separate legal entity under the Limited Liability Partnership Act, 2008, with incorporation and ongoing filing obligations. Eligibility of professional members and any professional-body restrictions should be checked before selecting this form. LLP incorporation information is available from the Ministry of Corporate Affairs.

Partnership bank account and operations

Banks ordinarily request the firm's PAN, partnership deed or LLP incorporation documents, address evidence, identity and KYC details of partners or authorized signatories, and an operating mandate. Shared facilities may include computers, secure software, printers, telephone systems and document management. Administrative and professional staff should be sized according to workload.

Capital requirement and estimated setup costs

There is no single statutory minimum investment for an ordinary tax-return preparation consultancy. Actual costs depend on location, business form, professional licensing, software subscriptions and the number of employees. Budget for:

Office deposit, furniture and utilities, if premises are rented.
Computers, printer or scanner, secure internet, cybersecurity and data backup.
Tax preparation, accounting, GST and TDS software and digital signature certificates where needed.
Business registration, professional fees, insurance and ongoing compliance.
Employee salaries, training and working capital for several months.

Prepare a cash-flow forecast based on expected recurring clients and seasonal return-filing demand rather than relying on an assumed fixed capital amount.

Registrations, taxation and ongoing compliance

PAN, TAN and income tax

A business may need PAN and, where required to deduct or collect tax, TAN. Maintain accounts, issue invoices and meet return-filing, TDS/TCS and advance-tax obligations as applicable. Check current forms and procedures on the Income Tax e-Filing portal.

GST registration

Section 22 of the CGST Act, 2017 establishes turnover-based registration liability, subject to applicable thresholds and conditions; Section 24 specifies categories requiring compulsory registration notwithstanding the ordinary threshold, subject to applicable exemptions and amendments. Registration requirements depend on the consultancy's supplies, location and business model. Use the official GST portal for current eligibility and filings.

Other registrations and data protection

Check state Shops and Establishments requirements, local permissions, employment law and professional tax where applicable. Eligible micro and small businesses may apply for Udyam registration. Protect clients' PAN, financial records, credentials and other personal data, and comply with applicable information-security and data-protection obligations, including provisions of the Digital Personal Data Protection Act, 2023 and related rules as brought into force. Official materials are available from MeitY.

Advertising and professional ethics

A consultancy can build its reputation through accurate educational content, clear service descriptions, referrals and timely client communication. Advertising by chartered accountants, advocates and other regulated professionals is subject to applicable professional standards and restrictions. Avoid misleading claims, promises of guaranteed refunds or tax savings, and unauthorized use of professional titles.

Practical startup checklist

Identify the services you are legally qualified and authorized to offer.
Choose a proprietorship, partnership or eligible LLP structure.
Complete applicable business, tax and professional registrations.
Set up a secure office, bank account and accounting systems.
Prepare engagement letters, fee schedules, confidentiality procedures and client KYC workflows.
Hire and train staff according to the workload and supervisory needs.
Maintain filing calendars and regularly verify changes in tax law and official procedures.
