Profession income tax applies to income earned from occupations that require specialised intellectual skills, such as doctors, lawyers, architects, or consultants. 

Examples of Professional Income

Both types of income are taxed under the Income Tax Act, 1961, with specific provisions and deductions available for business and professional taxpayers.

Income Tax Slab for Businessmen and Professionals (FY 2025 – 26 and AY 2026-27)

Business and professional income in India is taxed according to the individual income tax slab rates. Taxpayers can choose between the old tax regime, which allows deductions and exemptions, or the new tax regime, which offers lower slab rates with fewer deductions.

New Tax Regime Slabs (FY 2025–26)

₹4,00,001 – ₹8,00,000	5%

Tax Rebates (ITR for Businessman or Professional) for AY 2026-27

Under the revised regime for FY 2025–26, eligible resident individuals can avail of a nil tax up to ₹12 lakh due to the enhanced rebate framework. However, this does not apply to income taxed at special rates, such as certain capital gains. The earlier lower rebate threshold belonged to the older version of the new regime and should not be used for FY 2025–26 comparisons.

Presumptive Taxation for Business and Professional Income Tax

The Income Tax Act provides, within the framework of rules and regulations, that every such profession or business practice must maintain regular books of account and, accordingly, be audited.

Thus, to ease the hardships and burdens imposed on small taxpayers by these provisions, the presumptive taxation scheme under sections 44AD, 44ADA, and 44AE has been framed.

A person who adopts the presumptive taxation scheme can declare income at various specified rates, thereby relieving them of the otherwise tedious and cumbersome task of finalising the accounts and getting them audited.

Eligibility:

• Applicable to: Small businesses opting for simplified taxation under Section 44AD of the Income Tax Act.

Income Declaration:

• 6% of turnover for digital transactions.

Key Benefits:

• No need to maintain detailed books of accounts.
• No audit requirements, easing compliance for small businesses.

Exceptions: Businesses involved in the following are not eligible for presumptive taxation under Section 44AD:

• Life insurance agents.
• Commission-based income.
• Businesses of plying, hiring, or leasing goods carriages, as they fall under Section 44AE.

B. Presumptive Taxation for Professionals (Section 44ADA)

Eligibility:

• Applicable to professionals, such as doctors, lawyers, architects, accountants, and other specified professionals with gross receipts up to ₹75 lakh.

Income Declaration:

• Professionals can focus on their practice without worrying about complex tax filings.

2. Swift Loan Approval: Almost all banks demand ITR copies during loan processing. With that in hand, the whole process can go faster and easier.

3. Get Your Money Back: When TDS (Tax Deducted at Source) is greater than the actual tax liability, the only means to reclaim it is by filing your ITR.

4. Carry Forward Losses Into Future Profits: Filing your ITR permits the carry-forward of business losses, which helps reduce taxes on earnings in the future.

5. Establish Financial Credibility: ITR receipts are proof of income, which can be very handy during business transactions, when applying for investments, and even for visa applications.

Income tax returns for both businessmen and professionals are, besides the legally binding obligation, an opportunity to reduce their tax liabilities.
