What this calculator does

Test whether a bad debt can be deducted: it must be written off in the books, already taxed as income and net of recoveries. Shows the amount that passes the screen.

What you enter

Results are an educational screen based on the figures entered and the rule summarised above. They are not advice and do not replace the current Act, rule or accounting standard, or professional review of the facts.

Common questions

Is an ECL provision deductible?

No. An expected-credit-loss provision in the accounts is not an actual write-off of a particular debt.

Do recoveries of a written-off debt matter?

Yes. Amounts recovered later are taxable in the year of recovery, and the deduction on the original write-off is only for the net unrecovered amount.

Is a debt written off in the books but not yet legally irrecoverable deductible?

Yes. Under section 36(1)(vii) a write-off in the books is enough; the debt need not be proved irrecoverable in court.

How the calculation works

  1. Net write-off = the lower of the amount written off and (debt − recoveries).
  2. The deduction passes the screen only if the debt was taken into account as income earlier (or arises from money-lending) and was actually written off in the books.
  3. A provision for doubtful debts is not a write-off.

Background and professional notes

Finin2min: the 2-minute answer

A loss recognised in financial reporting is not automatically a tax deduction. The critical question is whether the specified debt has been actually written off as irrecoverable in the relevant books and whether statutory linkage to prior income or business of money-lending is satisfied.

Worked Indian example

An invoice of ₹2 lakh has ₹25,000 recoveries and a documented ₹75,000 write-off. The screened amount is ₹75,000 when the debt was part of taxable business income and evidence confirms the write-off. A general ECL provision without account-level write-off is not passed.

Important applicability and tax-year distinctions

Reconcile gross receivable, credit notes, recovery, ledger write-off and subsequent collections. Banks, money-lenders and provision-based special rules need their own treatment.
