ITR-3 Filing for Business and Professional Income: A Complete CA Guide
ITR-3 is the most complex individual ITR form — used for business income, professional income, and capital gains together. This guide covers every schedule, the presumptive vs actual accounting choice, and the most common errors.
Who Needs to File ITR-3?
ITR-3 is for individuals and HUFs who have income from:
- Business or profession (including freelancers, consultants, doctors, lawyers)
- Business income + salary income
- Business income + capital gains
- Partners in a partnership firm (only their share of profit + remuneration/interest from the firm)
ITR-3 is not used if the person opts for presumptive taxation under Section 44AD or 44ADA — they file ITR-4 (Sugam) instead. However, once a taxpayer who was filing ITR-4 opts out of presumptive taxation, they must file ITR-3 and cannot switch back to presumptive for the next 5 years.
Presumptive Taxation vs Actual Books
Section 44AD — Businesses
Eligible for: traders, manufacturers, and any business not specifically excluded. Turnover must not exceed ₹3 crore (increased from ₹2 crore if cash receipts/payments do not exceed 5%). Deemed profit: 8% of turnover (or 6% for digital receipts).
Benefit: No books of accounts required, no tax audit. Simply report 8%/6% of turnover as profit. Pay advance tax in one installment by March 15.
Restriction: If actual profit is less than 8%/6% of turnover, you cannot opt for 44AD — you must maintain books and get a tax audit done.
Section 44ADA — Specified Professionals
Eligible for: doctors, lawyers, architects, interior decorators, accountants (CAs!), engineers, technical consultants. Gross receipts must not exceed ₹75 lakh (₹37.5 lakh if actual profit is claimed lower than 50%).
Deemed profit: 50% of gross receipts. If the CA's receipts are ₹20 lakh, the deemed income is ₹10 lakh. No books required.
When Books and Tax Audit Are Mandatory
Books of accounts are mandatory under Section 44AA if:
- Business turnover exceeds ₹25 lakh in any 3 preceding years (or in the current year if new)
- Profession gross receipts exceed ₹10 lakh in any 3 preceding years
Tax audit under Section 44AB is mandatory if:
- Business turnover exceeds ₹1 crore (or ₹10 crore if cash transactions are less than 5%)
- Profession gross receipts exceed ₹50 lakh
- Opted for 44AD but actual profits are below the deemed percentage (triggers mandatory tax audit regardless of turnover)
ITR-3 — Key Schedules
Schedule BP — Business/Profession Computation
For clients with actual books, this is the P&L summary: gross receipts, expenses allowed under the Act, depreciation per Income Tax Act (different from Companies Act depreciation), and net business income.
Key deductions allowed in Schedule BP:
- Rent, rates, taxes (not income tax)
- Salary, bonus, commission to employees
- Repairs to business premises
- Depreciation per Schedule DPM (Income Tax Act rates — very different from Companies Act)
- Bad debts (actually written off in books)
- Scientific research expenditure
Schedule DPM/DOA — Depreciation
Depreciation under the Income Tax Act uses Written Down Value (WDV) method for most assets. Key rates: buildings 10%, plant & machinery 15%, computers 40%, motor vehicles 15% (for business use), furniture and fixtures 10%. New assets put to use for less than 180 days in the year get 50% depreciation in that year.
Schedule CG — Capital Gains
If the client has sold property, shares, or mutual funds during the year, Schedule CG must be filled. Business clients often have both business income and capital gains in ITR-3. The capital gains schedules in ITR-3 are identical to those in ITR-2.
Schedule OS — Other Sources
Interest income from savings accounts, FDs, NSC, family pension, winning from lotteries, etc. Remember: family pension is taxable under "other sources" (not salary), and a standard deduction of ₹15,000 or 1/3 of family pension (whichever is less) is available.
Top ITR-3 Mistakes CAs Must Avoid
- Claiming personal expenses as business expenses: Household expenses, personal travel, personal mobile bills — must be excluded from Schedule BP. Any such expenses added back will be detected in scrutiny.
- Not computing depreciation per Income Tax Act rates: The depreciation claimed in ITR-3 must follow IT Act block-of-assets method, not the depreciation in the P&L prepared under Companies Act or AS.
- GST collected reported as income: GST collected from customers is a liability and should not appear as turnover or income. Turnover in ITR-3 should be excluding GST (or a clear reconciliation note should be available).
- Not matching ITR-3 turnover with GSTR-9 turnover: The GST portal's AIS shows the registered person's turnover. Any significant mismatch triggers a compliance notice.
