The clock is ticking. Jul 31, 2026 is the final date to file Income Tax Returns for FY 2025-26, and most importantly for millions of salary-drawers, this is the most crucial tax date of the year! If it is not used, one cannot benefit from the Old Tax Regime, won't be able to transfer any capital losses, and will face late filing penalties up to Rs 5,000 as per Section 234F.

But beyond avoiding penalties, there is a more important question: are you filing strategically? The New Tax Regime - now the default for all individual taxpayers - has fundamentally changed what you can and cannot claim. Understanding these rules before you hit "submit" could mean the difference between paying more tax than necessary and keeping more of what you earned.

This guide covers 10 last-minute tax-saving strategies, the most common filing mistakes to avoid, and a clear comparison of the New vs Old Tax Regime to help you file right.

New vs Old Tax Regime: Which Is Better for You?

Before any strategy discussion, the single most important decision is choosing the right regime. This year, the choice carries higher stakes than ever.

The New Tax Regime is now the default. If you do nothing, you are taxed under it. It offers lower slab rates but eliminates most popular deductions - no Section 80C, no 80D, no HRA exemption, no home loan interest deduction under Section 24(b).

The Old Tax Regime retains all those deductions but charges higher slab rates. It remains beneficial for taxpayers with significant, documented deductions.

New Tax Regime Slabs for FY 2025-26

The headline benefit of the Tax New Regime is the Section 87A rebate of up to Rs 60,000 - which completely wipes out tax for resident individuals with taxable income up to Rs 12 lakh. Under the New Regime, salaried employees get a standard deduction of Rs 75,000 on top, and their gross income up to Rs 12.75 lakh is effectively tax-free under the new regime.

New vs Old Tax Regime: Quick Comparison

Rule of thumb: The New Regime is generally better if your total deductions under the Old Regime are less than Rs 3.75 lakh. The Old Regime benefits those with significant 80C investments, HRA, and home loan interest claims.

10 Last-Minute Tax-Saving Strategies Before Filing ITR

1. Claim the Full Standard Deduction

Salaried individuals and pensioners get a flat Rs 75,000 standard deduction under the New Tax Regime - no documentation required. Ensure this is correctly reflected in your return. Many taxpayers miss this or leave pre-filled data unchecked.

2. Check Your Section 87A Rebate Eligibility

If your taxable income (after standard deduction) is Rs 12 lakh or below under the New Regime, your net tax liability is zero — thanks to the Rs 60,000 rebate. The portal calculates this automatically, but verify the figure before submitting, particularly if you have any capital gains or special-rate income, as these fall outside the rebate's scope.

3. Maximise NPS Employer Contribution - The New Regime's Hidden Deduction

The most significant changes are that most of the deductions have been done away with in the New Regime, while Section 80CCD(2) – employer's contribution to NPS – will continue to be available. The top-up amount that the employer can contribute to the NPS Tier-1 account is 14% of basic salary and DA, which is also tax-deductible, in addition to the standard deduction of Rs 75,000. This is a good thing to discuss with your employer for the upcoming fiscal year, particularly if you haven't already been maximizing it; there can be a significant tax saving for those with higher incomes.

4. Cross-Check Form 26AS, AIS, and TIS Before Filing

The most frequently occurring reason for tax notices is a disparity between the income that has been recorded in your ITR and what the Income Tax Department systems record. Check three documents prior to filing: Form 26AS (tax credit), Annual Information Statement (AIS), Taxpayer Information Summary (TIS). Ensure that TDS deducted by the employer is reflected in Form 16, bank interest is reflected correctly and any dividend income from mutual funds or shares is captured.

5. Don't Miss Exempt Income Disclosure

Many taxpayers would not be aware that the income of an agricultural income, interest from PPF, certain allowances etc. is exempt income but still has to be reported in schedule EI of ITR. In addition, there is a new residual disclosure row included in the updated filing utility for AY 2026-27 to be added for transparency. It may lead to questions if this is not done.

6. Report All Capital Gains Accurately

Capital gains from equity mutual funds, stocks and/or property should be reported in full, irrespective of the exemption limit. STCG from Section 111A and LTGC from Section 112A is not covered under rebate under Section 87A and is taxed at special rates (20% and 12.5% respectively). Download your capital gains statement from your broker/mutual fund website in FY 2025-26 if you sold any equity shares and compare it carefully with the pre-filled data.

7. Choose the Right ITR Form

Incorrectly filed ITR forms are considered as a defective return and will have to be corrected and re-filed - forfeiting the original filing date. A major change in AY 2026-27 enables individuals owning two house properties to opt for filing ITR-1 (Sahaj) instead of filing ITR-2 which is a complex form. Please look for the appropriate form before moving on to the next question.

8. If Choosing the Old Regime, File Before July 31 - Not After

This is very important and often overlooked. The choice of Old Tax Regime has to be done at the time of filing a return by July 31, 2026. The penalty for filing a late return includes a de facto "default" into the New Tax Regime, in any case. A late return puts you on the Old Tax Regime, even if the Old Tax Regime works out cheaper for you. For taxpayers claiming large deductions, this one rule makes filing more critical!

9. Verify and Submit - Don't Leave It Pending

Many taxpayers complete their ITR filing but forget the e-verification step. An unverified return is legally treated as not filed by the Income Tax Department — even if you uploaded it on July 30. E-verification must be completed within 30 days of uploading using an Aadhaar-linked OTP, net banking, or Bank Account Validation Code. Without verification, your filing is invalid.

10. File Even If Tax Liability Is Zero

Even if there is no taxable income (after applying rebates and deductions) you are required to file ITR if your gross income is more than the basic exemption limit (New Regime - Rs 4 lakh, Old Regime - Rs 2.5 lakh).  A completed ITR is also necessary for other reasons besides compliance – like as proof of income while applying for a home loan, visa, credit card or insurance policy of more than Rs. 50,000.

Common ITR Filing Mistakes to Avoid in 2026

Ignoring pre-filled data errors: The portal auto-imports salary, TDS, and interest income - but errors in employer reporting or bank data can carry through. Before submitting, always double-check pre-filled information with your own documents.

Missing income from multiple sources: Freelance income, rental income, fixed deposit interest, and dividend income are often not reported. The AIS captures most of these from third-party sources - and mismatches between AIS and your ITR trigger automated notices.

Not disclosing foreign assets: Taxpayers holding foreign bank accounts, mutual funds, or property overseas must disclose these in Schedule FA. Under the Black Money Act, one has to face very severe consequences for not disclosing.

Incorrect bank account details: f the account number or IFSC code is wrong, it causes the delay in refunds or the redirection of funds to the wrong account. Please ensure that your pre-validated bank account is correct in the portal before submitting.

Missing the e-verification deadline:  As mentioned above, failing to upload e-verification within 30-days of the ITR filing is an invalid filing.

Key Deadlines for ITR Filing AY 2026-27

Is the New Tax Regime Really Worth It?

The New Tax Regime offers a good reduction in taxable income and reduced documentation requirements for people with salaries who don't have a big 80C investment,mHRA or home loan interest. But for those with a moderate income, the New Regime becomes more appealing as the Rs 12.75 lakh effective exemption for them, plus the employer NPS deduction, eliminates most of the tax liability.

But if a taxpayer claims Rs 2 lakh tax deductions under 80C by claiming 100% of his home loan interest, has health insurance premiums of over Rs 50,000 and avails 100% of the 80D benefit, he can still end up with lower net tax in the Old Regime. The calculation is not uniform – and a quick comparison on the Income Tax Department's portal tax calculator before filing is the most crucial last minute step that a taxpayer can take.

FAQ: ITR Filing 2026

What is the last date to file ITR for FY 2025-26? For salaried and ITR-1/ITR-2 (without audit requirements) it is July 31st 2026.

Is income up to Rs 12 lakh tax-free in 2026? Yes, for resident individuals with taxable income of up to 12 lakh, the entire taxable income becomes exempt under the New Tax Regime, thanks to the rebate of Rs 60,000 in the section 87A of the Income Tax Act, 1961. The effective cap for salaried employees increases to Rs 12.75 lakh – the Rs 75,000 standard deduction.

Can I switch from New to Old Tax Regime while filing? Yes - salaried individuals without business income can switch between regimes every year, but must do so before the July 31 deadline. Filing a belated return after this date locks you into the New Regime.

What is the penalty for late ITR filing? The late fee fee is Rs 5,000 if the income is greater than Rs 5 lakh and Rs 1,000 if it is lower than Rs 5 lakh in case of late filing as per Section 234F. Further, you are unable to utilize loss carry forward and will have to implement the New Tax Regime.

What deductions are still available under the New Tax Regime? The New Regime allows the Rs 75,000 standard deduction, employer's NPS contribution under Section 80CCD(2), and the Section 87A rebate. Other popular deductions such as 80C, 80D, HRA and Section 24(b) are not available.
