Rule 42 of the Income-tax Rules, 2026

Rule 42 — Special provision regarding interest on bad and doubtful debt of specified financial institution. Made under s.56 of the Income-tax Act, 2025.

Where this rule sits

Rule 42 gives effect to Section 56 of the Income-tax Act, 2025. A rule cannot go beyond the section it serves: where the two seem to differ, the section governs.

What this rule does

Sub-rule (1) identifies the categories of bad or doubtful debts for which section 56 applies to a public financial institution, scheduled bank, State Financial Corporation and State Industrial Investment Corporation. In relation to a loan or advance, clause (a) covers: interest or an instalment of principal overdue for more than one hundred and eighty days; an overdraft or cash credit account that remains out of order; a bill overdue for more than one hundred and eighty days in the case of bills purchased and discounted; an instalment of principal or interest overdue for two crop seasons for short duration crops; the same overdue for one crop season for long duration crops; a liquidity facility outstanding for more than one hundred and eighty days for a securitisation transaction under the Reserve Bank of India (Securitisation of Standard Assets) Directions, 2021; and, for derivative transactions, overdue receivables representing positive mark-to-market value of a derivative contract unpaid for one hundred and eighty days from the specified due date for payment. In relation to an account, clause (b) covers: a working capital borrowal account with irregular drawings for a continuous period of one hundred and eighty days even though the unit may be working or the borrower's financial position is satisfactory, with outstandings based on drawing power calculated from stock statements older than six months deemed irregular; regular or ad hoc credit limits not reviewed or renewed within one hundred and eighty days from the due date or date of ad hoc sanction; erosion in the value of security where realisable value is less than 50% of the value assessed by the bank or accepted by the Reserve Bank of India at the last inspection; and realisable value, as assessed by the bank, approved valuers or the Reserve Bank of India, less than 10% of the outstanding in the borrowal accounts.

Sub-rule (2) does the same for a public company, on a two-part definition. A doubtful asset is a debt which has remained a non-performing asset of the specified nature for a period exceeding two years, and the non-performing assets listed are: an asset on which interest has remained overdue more than one hundred and eighty days; a term loan, other than one granted to an agriculturist or a person whose income depends on the harvest of crops, inclusive of unpaid interest, where the instalment or the interest is overdue more than one hundred and eighty days; a demand or call loan overdue more than one hundred and eighty days from the date of demand or call, or with interest so overdue; a bill overdue more than one hundred and eighty days; interest on a debt or income on receivables under 'other current assets' in the nature of short-term loans or advances overdue more than one hundred and eighty days; dues on account of sale of assets, services rendered or reimbursement of expenses overdue more than one hundred and eighty days; lease rental and hire purchase instalments overdue more than one hundred and eighty days; a term loan to an agriculturist or a person dependent on the harvest of crops where principal or interest remains unpaid for two crop seasons beyond the due date for short duration crops or one crop season beyond the due date for long duration crops; and the balance outstanding, including accrued interest, under all credit facilities to the same borrower or beneficiary once any of those facilities becomes a non-performing asset. A loss asset is an asset identified as a loss asset and considered as uncollectible but not written off by the assessee.

Sub-rule (3) defines the terms the tests turn on. An overdraft or cash credit account is "out of order" if the outstanding balance remains continuously in excess of the sanctioned limit or drawing power for one hundred and eighty days, or if it is below that limit but there are no credits continuously for one hundred and eighty days, or credits are not enough to cover the interest debited during the previous one hundred and eighty day period. A long duration crop is a crop with a crop season longer than one year, and a short duration crop is one that is not a long duration crop; the crop season for each crop is the period up to harvesting of the crops raised, as may be determined by the State Level Bankers' Committee in each State. "Public company" is narrow: a public company within the meaning of section 2(71) of the Companies Act, 2013, whose main object is carrying on the business of providing long-term finance for construction or purchase of house in India for residential purposes, and which is registered under section 29A of the National Housing Bank Act, 1987 or in accordance with the Housing Finance Companies (nhb) Directions, 1989 or the Non-Banking Financial Company – Housing Finance Company (Reserve Bank) Directions, 2021.

Why it is there

Section 56 changes when interest on a bad or doubtful debt is brought to tax for the institutions it covers, but it does not say which debts count as bad or doubtful, and lenders and the Department would otherwise argue that question account by account. Rule 42 answers it with the same objective markers a lender already uses for prudential classification — days overdue, out-of-order accounts, erosion of security — so the tax position follows a test that is verifiable from the loan records. Sub-rule (3) closes the definitional gaps that would otherwise reopen the argument.

What this means in practice

The rule classifies debts; it does not decide the tax treatment, which is section 56's. Two consequences follow from that division. First, an institution outside the five classes in sub-rules (1) and (2) gets nothing from this rule however overdue its debts, and "public company" here is not the Companies Act meaning alone — rule 42(3)(c) adds the housing-finance object and the registration requirement, so an ordinary public company is outside it. Second, the tests are objective and some of them bite on a healthy borrower: rule 42(1)(b)(i) says so expressly, catching an account with irregular drawings for a continuous one hundred and eighty days even though the unit may be working or the borrower's financial position is satisfactory. Note also that the two-year test in sub-rule (2) is a second layer, not an alternative — the asset must first be a non-performing asset of the listed nature and then have remained so for a period exceeding two years — and that once any one facility of a borrower becomes non-performing, rule 42(2)(a)(ii)(I) pulls in the balance outstanding under all his facilities, including accrued interest.

An example

Illustrative only, and invented for this page. The figures are chosen to show the requirement biting, not taken from any real matter.

A scheduled bank has a cash credit account with a sanctioned limit of Rs. 2 crore. The balance stays at Rs. 1.8 crore, inside the limit, but no credits are received for a continuous one hundred and eighty days. The account is out of order under rule 42(3)(a)(ii) even though the limit was never exceeded, so the interest on it falls within the categories in rule 42(1)(a)(ii) and section 56 applies to that interest. Had the borrower deposited enough to cover the interest debited in that period, the account would not have been out of order on this test.

Where you meet this rule

A borrower never meets this rule; the lender does, in its own asset classification records and in the reconciliation between its books and its return, and the Assessing Officer meets it when testing an institution's claim that interest on a particular account is governed by section 56.

What people get wrong

What this page does not tell you. It does not reproduce the rule. Everything above was written from the rule’s own text as the Income Tax Department publishes it — the text is here. A rule is subordinate legislation: it prescribes the method, the form or the period, and it cannot enlarge the charge the section imposes. Where a figure matters, read the sub-rule it comes from.
