Section 37 Actual-Payment Deductions: Tax, PF, Interest and Leave
Legacy section 43B is consolidated into section 37 of the Income-tax Act, 2025.
Specified taxes, employer welfare contributions, certain interest and leave-encashment liabilities are allowed on actual payment, with due-date relief only where the provision permits.
Legal or Computational Framework
Governing rule
Employee contributions have stricter due-date treatment. MSME clause treatment is also distinct and does not receive the ordinary return-due-date cure.
Correct calculation method
Create liability category ledger; record statutory/contract due date and actual payment; identify return-due-date relief; disallow unpaid amount; claim in payment year.
Step-by-step workflow
- Create liability category ledger.
- record statutory/contract due date and actual payment.
- identify return-due-date relief.
- disallow unpaid amount.
- claim in payment year.
Worked example
GST payable in March and paid before the return due date may qualify under the applicable relief; employee PF paid after the welfare-law due date needs separate treatment.
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 |
