- Audit cases: October 31 of the assessment year

How is presumptive taxation under Section 44AD different from regular taxation? +
| Feature | Regular Taxation | Presumptive Taxation (Section 44AD) |
|---|---|---|
| Applicability | All businesses | Businesses with turnover ≤ ₹2 crore (₹3 crore for digital transactions) |
| Tax Calculation | Based on actual profit (Revenue – Expenses) | 8% of turnover (6% for digital transactions) |

| Advance Tax | Pay in 4 installments (15%, 45%, 75%, 100%) | 100% by March 15 |
Key Benefit: Simplifies compliance for small businesses by eliminating complex bookkeeping. However, if your actual profit is less than 6-8% of turnover, regular taxation might be more beneficial.
What expenses can I claim as business deductions under Indian tax laws? +
Under Section 30 to 37 of the Income Tax Act, you can claim the following as legitimate business expenses:
Fully Deductible Expenses:
- Rent for business premises
- Salaries and wages (including PF, ESIC contributions)
- Repairs and maintenance of assets
- Insurance premiums for business assets

Non-Deductible Expenses:

How does GST impact my income tax calculations? +
GST and income tax are separate tax systems, but they interact in several ways:
Key Interactions:
- Revenue Recognition:
- Income tax is calculated on your net revenue (after excluding GST)
- If you collect ₹1,18,000 (including 18% GST), only ₹1,00,000 is taxable income
- Input Tax Credit (ITC):
- GST paid on business expenses can be claimed as ITC (reduces GST liability)
- However, the expense amount before GST is deductible for income tax
- GST Audit Impact:
- If your turnover exceeds ₹2 crore (₹5 crore for some states), GST audit is required
- This automatically triggers income tax scrutiny in many cases
- Cash Flow Management:
- GST is payable monthly/quarterly, while income tax is annual
- Plan for both liabilities to avoid cash crunches
- GST on Expenses:
- For expenses like rent, professional fees – the GST portion is not deductible for income tax
- Only the base amount is considered as expense
Common Mistakes to Avoid:
- Claiming GST collected as income (it’s a liability until remitted)
- Not reconciling GST returns with income tax returns
- Missing ITC claims that could reduce your GST burden
Expert Advice: Maintain a separate GST ledger and reconcile it monthly with your income tax books. The GST Portal provides tools to cross-verify your transactions.
What are the consequences of not filing business income tax return on time? +
Failing to file your business income tax return by the due date can have serious consequences:
Immediate Penalties:
- Late Filing Fee (Section 234F):
- ₹1,000 if income ≤ ₹5 lakh
- ₹5,000 if income > ₹5 lakh (filed by Dec 31)
- ₹10,000 if filed after Dec 31
- Interest on Tax Due (Section 234A): 1% per month on unpaid tax amount
- Loss Disallowance: Cannot carry forward business losses
Long-Term Consequences:
- Scrutiny Risk: Higher chance of being selected for income tax scrutiny
- Loan Rejections: Banks and financial institutions may reject loan applications
- Visa Issues: Many countries require tax compliance proof for visa applications

What to Do If You Missed the Deadline:

- If you have a valid reason, apply for condonation of delay
- Consult a CA to handle any notices from IT Department
