Module G: Interactive FAQ
What qualifies as ‘business income’ under Income Tax Act?
Business income includes any profit or gain from:
- Any trade, commerce, or manufacture
- Profession (doctors, lawyers, architects, etc.)
- Vocation (regular independent activity)
- Any adventure in nature of trade
- Export incentives, cash discounts, and bad debts recovered
Exclusions: Agricultural income, capital gains, and income from other sources.
How is depreciation calculated for tax purposes?
Depreciation is calculated using the Written Down Value (WDV) method:
- Assets are grouped into blocks (Building, Plant & Machinery, Furniture, etc.)
- Each block has a prescribed rate (5% to 100%)
- Depreciation = Opening WDV × Rate/100
- Additions during year are depreciated at 50% of normal rate
Example: A computer (40% rate) purchased for ₹1,00,000 would have:
- Year 1: ₹40,000 depreciation
- Year 2: ₹24,000 (60,000 × 40%)
- Year 3: ₹14,400 (36,000 × 40%)
What expenses are not allowed as deductions for business income?
The Income Tax Act specifically disallows these expenses:
- Personal expenses (Section 37)
- Capital expenditures (added to asset cost)
- Wealth tax payments
- Income tax payments
- Penalties or fines for law violations
- Provision for bad debts (only actual write-offs allowed)
- Expenses related to exempt income
- Cash payments > ₹10,000 per day per person (Section 40A)
Note: Some disallowed expenses may be allowed in subsequent years when actual payment is made.
How does presumptive taxation under Section 44AD work?
Presumptive taxation simplifies compliance for small businesses:
- Eligibility: Businesses with turnover ≤ ₹2 crore (₹3 crore if 95% digital transactions)
- Presumed Income: 6% of turnover (8% if turnover ≤ ₹2 crore and cash receipts)
- Benefits:
- No need to maintain books of accounts
- No audit required
- Advance tax in one installment by 15th March
- Limitations:
- Cannot claim further deductions
- Must be opted for 5 consecutive years
- Not available for commission/agency businesses
Example: A retailer with ₹1.8 crore turnover would pay tax on ₹10.8 lakh (6%) instead of actual profits.
What are the consequences of under-reporting business income?
Under-reporting can lead to severe penalties under Section 270A:
| Misreporting Type | Penalty Rate | Minimum Penalty |
|---|---|---|
| Misreporting of income | 200% | ₹20,000 |
| Under-reporting of income | 50% | ₹10,000 |
| Other cases | 200% | ₹50,000 |
Additional consequences may include:
- Interest at 1% per month on tax due (Section 234A/B/C)
- Prosecution under Section 276C (6 months to 7 years imprisonment)
- Blacklisting for government contracts
- Difficulty in obtaining loans
Always maintain proper documentation to substantiate your income and expenses.
How does GST impact business income tax calculation?
GST interacts with income tax in several ways:
- Input Tax Credit:
- GST paid on purchases can be claimed as ITC
- Reduces your net GST liability
- Does not directly affect income tax
- Turnover Calculation:
- Income tax turnover = GST turnover + exempt supplies
- GST turnover excludes taxes collected
- Audit Requirements:
- GST audit (₹2 crore turnover) is separate from tax audit (₹1 crore)
- Both may be required if thresholds crossed
- Documentation:
- GST invoices serve as proof for income tax expenses
- Mismatches between GST and IT returns trigger notices
Best Practice: Reconcile your GST returns (GSTR-1, GSTR-3B) with your income tax computations annually.
What are the key differences between old and new tax regimes for business income?
Comparison of regimes for business/profession income:
| Feature | Old Regime | New Regime |
|---|---|---|
| Tax Slabs | 3 (10%, 20%, 30%) | 6 (0% to 30%) |
| Basic Exemption | ₹2,50,000 | ₹3,00,000 |
| Deductions (80C, 80D, etc.) | Allowed | Not allowed (except 80CCD(2) and 80JJAA) |

| Surcharge Threshold | ₹50 lakh | ₹50 lakh |
| Rebate (Section 87A) | ₹12,500 (Income ≤ ₹5 lakh) | ₹25,000 (Income ≤ ₹7 lakh) |

For business income specifically:

- New regime may benefit those with income < ₹15 lakh
