Section 44AD Advance Tax: Why 15 March Matters
A presumptive taxpayer under section 58/legacy 44AD generally pays the entire advance-tax liability by 15 March instead of quarterly instalments.
For broader context, see the Income Tax and Salary Hub.
Paying after the deadline can trigger interest even when paid before the year ends.
Legal or Computational Framework
Governing rule
Advance tax applies when estimated tax payable reaches the statutory threshold. Presumptive taxpayers receive the single-instalment concession, not an exemption.
Use the Advance Tax Instalment Planner — FY 2026–27 to apply these points to your figures or facts.
Correct calculation method
Estimate presumptive profit and other income; compute tax and credits; pay 100% by 15 March; update for late-year income and reconcile challans.
Step-by-step workflow
- Estimate presumptive profit and other income.
- Compute tax and credits.
- Pay 100% by 15 March.
- Update for late-year income and reconcile challans.
- Reconcile the input with official statements and supporting records.
- Calculate both legal eligibility and final tax impact.
- Record the effective date and review trigger.
Worked example
Estimated tax after TDS is ₹1.2 lakh. Paying ₹1.2 lakh on 25 March may still create instalment interest because the special due date was 15 March.
The example is an illustration, not a substitute for the taxpayer's facts. A change in status, period, payment mode, document, city, asset, relationship or scheme can change the result.
Why generic pages get this wrong
Search pages often state a rate or limit without identifying the governing base. The calculation must distinguish gross receipt from taxable profit, tax from TDS, a deduction from an exemption, salary from business income, and an accounting entry from the tax treatment.
Decision matrix
| Decision point | Required treatment |
|---|---|
| Legal year | Use the Act, rules and notification effective for the income or transaction period |
| Taxpayer category | Confirm residence, age, entity, employee/business status and regime |
| Calculation base | Use the statutory definition rather than CTC, net bank receipt or accounting label |
| Ceiling or rate | Apply actual-amount, percentage, shared, lifetime and gross-income limits in sequence |
| Documentation | Link every input to an invoice, statement, contract, certificate or official record |
| Final output | Show tax, surcharge, cess, interest and TDS/TCS credits separately |
Related concepts on this topic
This advance-tax deadline connects directly to how the presumptive profit itself is computed: Section 58/legacy 44AD sets deemed profit at 6% of digital receipts or 8% of cash receipts, and that estimated presumptive profit - not actual bank-account cash - is the base the 15 March advance-tax figure should be calculated from.
What Generic Pages Miss
- Ignoring excluded business.
- Mixing turnover and receipts.
- Misclassifying non-account-payee cheques.
- Forgetting opt-out history.
- Treating deemed profit as final tax.
