Common questions

FAQs.

What is disallowed under Section 40(a)(ia)?
30% of any sum payable to a resident, on which tax is deductible at source under Chapter XVII-B, is disallowed as a business expense if the tax was not deducted, or was deducted but not deposited on or before the return-filing due date under Section 139(1). Section 40(a)(i) applies the same logic at a 100% disallowance rate for payments to non-residents/foreign companies.
Is the disallowance permanent, or can it be claimed later?
It is a timing disallowance, not permanent. The second proviso to Section 40(a)(ia) allows the expense as a deduction in the year the TDS is actually deducted and deposited, even if that is a later year — so the amount isn't lost, only deferred to the year of actual compliance.
Does the disallowance apply if the payee has already paid tax on that income?
A separate relief exists (linked to the first proviso to Section 201(1)) where the payer is not treated as an assessee-in-default for non-deduction if the resident payee has furnished their return of income, included the relevant sum in that return, and paid the tax due — but this doesn't automatically waive the Section 40(a)(ia) expense disallowance itself; the two provisions operate on different questions and should be tested separately, with a certificate/Form 26A obtained from the payee's CA to evidence the payee-side compliance where relied upon.
