Itr 3 and itr 4 last dates?

The standard deadline for ITR-3 and ITR-4 is July 31, 2026 for non-audit cases; do not rely on unofficial sources claiming an August extension without a CBDT notification. Furthermore, an MSME owner with capital gains from shares cannot use ITR-4 and must file ITR-3 instead.

Hi sir, I'm able to see only 31st August as due date while filling the return in the drop down list for ITR3 non-audit case please clarify. Unable to see 31st July

ITR-3 & 4 are for business income, irrespective of the fact that total income includes business income and Capital gain, or income under any other heads.

Being MSME will not change above. 

Dates of filing return is 31 Aug for non-audit cases and 31 oct for audit cases. 

That is the reason dates are shown so in ITR forms too. You can check Tax calendar for Aug-31 at https://eportal.incometax.gov.in/iec/foservices/#/TaxCalc/calender 

However, it is always suggested not to wait for last date. If all data is ready, better file ITR timely.
