Missed June Advance Tax Instalment? September 15 Deadline Explained
Advance tax means paying income tax during the year instead of waiting until the end.
Some taxpayers must pay it in several instalments.
If someone missed the June 15 payment, they can still pay it later.
They may also have to pay interest on the delayed amount.
The next payment is still due on September 15.
For example, someone expecting to owe ₹1 lakh would have had to pay ₹15,000 by June 15 and ₹45,000 by September 15.
A shortfall can attract 1% monthly interest under Section 234C.
If less than 90% of the total tax is paid by March, further interest may apply under Section 234B.
Taxpayers who missed the June 15, 2026, advance tax deadline can still pay the instalment with applicable interest.
Advance tax is mandatory when net tax liability after TDS, TCS and tax credits is ₹10,000 or more.
The September 15 instalment remains payable even if the June instalment was missed.
Section 234C may impose interest of 1% per month on the shortfall, with any part of a month treated as a full month.
Section 234B applies if at least 90% of total tax liability is not paid by March, with interest starting from April 1.
