Complete Guide to Tax Season 2025: Deadlines, Forms & Tips

Some folks like to get a head start, while others (you know who you are!) tend to leave it for the last stretch of tax season. Whichever type you are, it helps to know what’s due when—so you don’t miss out on important dates or benefits.

When is the Start Date to File ITR for FY 2024-25?

As with every year, the government’s e-filing portal usually opens right at the start of April. For this round, you should be able to start uploading your return from April 1, 2025. It’s always nice to start early—especially because by mid-tax season, things tend to get a bit busier (and websites slower).

When is the Last Date to File ITR?

Mark this one: July 31, 2025. That’s the tax filing deadline 2025 for most of us—salaried employees and anyone not required to go through an audit.

If your situation involves an audit, the deadline gets pushed to October 31, 2025. And if international transactions are part of your books, you’ve got until November 30, 2025.

Either way, sooner is better. No one likes filing returns in the final week of tax season deadline rush.

Consequences of Missing the ITR Filing Deadline

Missing the tax filing deadline 2025 isn’t ideal. If it happens, a late fee kicks in—up to ₹5,000. You might also lose the chance to carry forward capital losses and may face interest charges on unpaid taxes.

And honestly, it’s just extra stress. Filing during the regular tax return season keeps things simple and avoids unnecessary headaches.

What if ITR Filing is Missed?

Yes. If you miss the original cut-off, you can still submit what’s called a belated return by December 31, 2025. Keep in mind though, the penalties and interest apply. And if you had any deductions or loss adjustments planned, you might lose some of those benefits if you file outside the usual tax season.

What if ITR Filing has Errors?

Happens to the best of us. If you realize after filing that you entered something wrong, no worries—you can submit a revised return (again, until December 31, 2025).

This is why filing early in tax season helps—you’ve got plenty of time to make corrections well before the tax season deadline comes up.

What are Financial Year (FY) and Assessment Year (AY)?

A lot of people mix these terms up. Think of Financial Year (FY) as when you actually earned the income. So this time it’s April 1, 2024 to March 31, 2025.

Assessment Year (AY) is when your return for that income is processed—so, for this round, it’s AY 2025-26. Simple enough once you remember it.
