Updated tax returns may be allowed when a taxpayer reduces a previously claimed loss, per proposed Finance Bill changes.
Section 263(6) permits an updated return within 48 months but bars updated returns that are returns of loss, limits reductions in tax liability or increases in refund, and restricts filing during or after assessment, reassessment, search, survey or prosecution. The Finance Bill, 2026 proposes to amend section 263(6) to allow filing an updated return where the taxpayer reduces the amount of loss claimed in a duly filed return of loss, and to make parallel amendments to the Income-tax Act, 1961.

Updated tax returns allowed in response to reassessment notices, with extra tax payable and penalty exclusion for that income.
Permits furnishing an updated return in response to a reassessment notice within the notice period, precludes alternative filing in response to that notice, maintains existing restrictions on updated returns, and requires payment of prescribed additional income tax; where filed in pursuance of the notice an extra 10% of aggregate tax and interest is payable and that income will not form the basis for penalty.

Foreign asset disclosure scheme for small taxpayers offers a time-bound window with tax/fee and limited immunity.
The proposed FAST-DS 2026 provides a time bound window for small taxpayers to declare undisclosed foreign assets and foreign sourced income, requires payment of tax or a fee based on nature and source of acquisition, and grants limited immunity from penalty and prosecution under the Black Money Act for matters covered by the declaration, while excluding cases involving prosecution or proceeds of crime; the scheme is included in the Finance Bill, 2026 (Clauses 114-128) and will commence from a date notified by the Central Government.

Relaxation of prosecution under the Black Money Act excludes small-value foreign assets from sections 49 and 50.

Union Budget change limits block assessment period for third parties when undisclosed income pertains to a single tax year.
Section 295 currently requires that seized material relating to undisclosed income of a person other than the specified person be handed to that person's AO and that the other person undergo block assessment with the same block period; the Finance Bill proposes amending Section 295(2) to limit the period of block for such third parties, particularly where the undisclosed income pertains to a single tax year, with effect for searches or requisitions initiated on or after 1 April 2026.

Union Budget 2026-27 proposes using initiation of search as the trigger for block assessment and extending the period to eighteen months.

Union Budget changes penalty process: under-reporting penalties imposed within assessment order; interest charged post-appeal, effective April 2027.

Interest under the tax recovery provision will be charged only after an appellate order by the first appellate authority or tribunal in appeals from dispute resolution forum orders.

The amendment is effective 1 April 2026 for tax year 2026 27 onward.
