Do you need to file this year?
Filing is mandatory if your total income before deductions crosses the basic exemption limit — ₹2.5 lakh under the old regime (₹3 lakh for senior citizens, ₹5 lakh for super senior citizens), or ₹4 lakh under the new regime, regardless of age.
But a few situations require you to file even if your income is below that limit:
- ✓You've deposited more than ₹1 crore in one or more current accounts
- ✓You've spent more than ₹2 lakh on foreign travel for yourself or someone else
- ✓Your electricity bill for the year crossed ₹1 lakh
- ✓You hold foreign assets or foreign bank accounts, or you're a signing authority on one
- ✓You want to carry forward a loss, or claim a refund of TDS already deducted

If you're a freelancer, consultant, or small business owner
- ✓All of the above, plus invoices raised and payments received during the year

The filing process, step by step
Using your PAN as the user ID.
Against your own income records. Mismatches here are the single biggest cause of notices later.
Based on your income sources, using the table above.
The new regime applies by default unless you actively opt for the old one.
Either pre-filled from your Form 16 and 26AS, or entered manually if you're on ITR-3 or ITR-4.
And pay any balance tax due before submitting.
Using Aadhaar OTP, net banking, or a digital signature. Your return isn't considered filed until it's verified.
Old tax regime vs new tax regime: which one should you pick?
This decision alone can change your tax bill by tens of thousands of rupees, and it's the one thing most filers get wrong by defaulting without checking.
| New regime (default) | Old regime | |
|---|---|---|
| Basic exemption | ₹4 lakh, same for all ages | ₹2.5 lakh (below 60), ₹3 lakh (60–80), ₹5 lakh (80+) |
| Standard deduction | ₹75,000 | ₹50,000 |
| Effectively tax-free income | Up to ₹12.75 lakh for salaried, after standard deduction and Section 87A rebate | Up to roughly ₹5.5 lakh, after standard deduction and rebate |
| Deductions available | Very limited, mainly employer NPS contribution | 80C (up to ₹1.5 lakh), 80D, HRA, home loan interest, and more |
| Best suited for | Those with few deductions, or income comfortably under ₹12.75 lakh | Those with significant HRA, home loan interest, insurance, or 80C investments |
What it costs to file through Elixir Filings
Our professional fee varies by form complexity — ITR-1/2 for salaried filers is priced differently from ITR-3/4 for freelancers and small businesses, since the latter involves more reconciliation work. Whatever the final numbers for your situation, the same rule applies as everywhere else on the site: professional fee, and any applicable GST, shown upfront, before you commit to anything.
Why Chennai filers increasingly choose a professional over DIY
Chennai's taxpayers span salaried professionals, freelancers, NRIs, and business owners, each with a distinct income profile and a distinct set of ITR complexities. Here's where professional filing makes the most meaningful difference:
5 myths about ITR filing, cleared up
"If my employer deducted TDS, I don't need to file."
"I don't need to file if I have no tax to pay."
"NRIs don't need to file an Indian ITR."
"Once I switch to the new regime, I can't go back."
"A belated return is basically the same as filing on time."
Mistakes Chennai filers commonly make
What happens after you file
- ✓E-verify within 30 days. Your return isn't legally considered filed until it's verified, via Aadhaar OTP, net banking, or a digital signature.
- ✓Processing and intimation. The department typically processes returns and sends an intimation under Section 143(1) within a few weeks to a few months, confirming your return as filed or flagging a discrepancy.
- ✓Refunds, if applicable, are usually credited directly to your bank account once processing is complete, provided your bank account is pre-validated on the portal.
- ✓If you spot an error after filing, you can file a revised return. For AY 2026-27, that window now runs until 31 March 2027.
- ✓If you receive a notice, don't ignore it. Most are routine mismatches that are simple to respond to within the given timeline, but missing that timeline turns a minor issue into a bigger one.
What's new for AY 2026-27?
A few things changed this cycle that are worth knowing before you file, not after:
In previous years, most non-audit filers, salaried and business alike, shared the same July 31 deadline. This year, non-audit business and professional taxpayers filing ITR-3 or ITR-4 get until August 31, a full month later.
You can now revise a return up to 31 March 2027, later than the cutoff in previous years.
The Income Tax Act, 2025 comes into force from 1 April 2026, but since AY 2026-27 covers income earned in FY 2025-26, before that date, this year's filing is still governed entirely by the Income Tax Act, 1961. From next cycle, filings move to the new Act, which also replaces the terms "Previous Year" and "Assessment Year" with "Tax Year."
Budget 2026 made no changes to slab rates, the standard deduction, or the Section 87A rebate under either regime, so if you filed last year, the numbers you're working with are the same.
