Income tax return basics: who must file and what you need

Filing an income tax return is simpler than it looks once you know whether you are required to file, which regime suits you, and what to keep ready. This guide covers the essentials in plain terms — and flags the specifics that change each year, so you confirm them on the official portal rather than assume.

Overview

Who is required to file a return

The main trigger is income. If your total income before deductions exceeds the basic exemption limit for the year, you are generally required to file. But income is not the only trigger — filing can be required regardless of income in certain situations, commonly including:

  • Holding assets or signing authority over accounts outside India.
  • Depositing large amounts in bank or current accounts above notified limits.
  • Spending above notified thresholds on foreign travel or electricity.
  • Business turnover or professional receipts above specified limits.

Beyond the requirement, many people file voluntarily because it is useful: to claim a refund of excess TDS, to build an income record for loans and visas, and to carry forward certain losses. Because the exact exemption limit and conditions are revised periodically, confirm your position against the current rules on incometax.gov.in or ask us to check.

Regimes

Old versus new regime, in brief

India runs two parallel tax structures, and choosing between them is the decision that most affects your tax:

Old regimeNew regime
Slab ratesHigherLower
Deductions & exemptionsWide range available (investments, insurance, HRA, etc.)Most removed
Best suited toThose with significant deductions to claimThose with few deductions who prefer lower rates
DefaultOpt in each yearApplies by default in recent years

Compare both for your actual numbers

There is no universally better regime — it depends entirely on your deductions. The slab rates, thresholds and the exact mechanics of opting in or out are revised from year to year, so treat this table as the concept, not the current figures, and confirm the live rates on the official portal. The practical step is to compute your tax under both and pick the lower.

Documents

Documents to keep ready

Gathering these before you start makes filing quick and accurate:

  • PAN and Aadhaar — and they must be linked (see below).
  • Form 16 if you are salaried, from your employer.
  • Bank statements and interest certificates — savings, fixed deposits, bonds.
  • Capital-gains statements for any sale of shares, mutual funds or property.
  • Rent, home-loan and investment proofs for deductions you plan to claim (old regime).
  • Your Annual Information Statement (AIS) and Form 26AS from the portal, as a cross-check against what the department already has on record.

If you run a business, your books, GST returns and expense records feed the computation — our GST services and GST registration guide connect naturally here, since GST and income-tax records should tell the same story.

Deadlines

Due dates — confirm each year

For most individual taxpayers who are not subject to audit, the filing due date has commonly fallen on 31 July following the financial year, with later dates for audit and business cases. The department sometimes extends these dates, and the belated-return window and its late fee also apply after the due date.

Do not rely on last year's date

Because due dates are occasionally shifted, always confirm the current year's deadline on incometax.gov.in before you plan around it. Filing on time avoids the late-filing fee and interest and preserves benefits such as carrying forward certain losses.

One prerequisite people overlook: your PAN must be linked with Aadhaar and operative. If it is not — often because of a name or date-of-birth mismatch — sort that out first with our PAN correction guide, because an inoperative PAN interferes with filing and refunds.

Straight talk

Where we help — and where you may need a CA

Honest scope

We assist with return preparation and filing — organising your documents, computing income under both regimes where that helps, and filing on the portal — with a fixed quote before we start. For a simple salaried return with a clean Form 16, many people file themselves for free on the portal, and we will happily say so.

Some cases genuinely need a chartered accountant — tax audits, complex capital gains, business accounts requiring certification, or contested notices. When your case is one of those, we will tell you plainly rather than take on work that should sit with a CA.

This page is general information, not tax advice. Your specific liability depends on your full financial picture and the current year's law. For a view on when paid help pays for itself, see doing it yourself versus using us.

Before you decide

The bottom line

The difference between a smooth application and a stuck one is usually preparation, not luck. Preparation is precisely what you are paying us for — and at our prices, it is the cheapest insurance this process offers.

FAQs

Income tax filing, answered straight

Who is required to file an income tax return?
Broadly, you must file if your total income before deductions exceeds the basic exemption limit, and in certain other situations regardless of income — such as holding foreign assets, large bank deposits, high electricity spend, or significant foreign travel. Because the exact triggers and limits change, confirm your position against the current rules on incometax.gov.in or with us.
What is the difference between the old and new tax regime?
The old regime allows a range of deductions and exemptions but has higher slab rates; the new regime offers lower slab rates with most deductions removed. The new regime is the default in recent years, but you can usually opt for whichever works out better for you. The right choice depends on your deductions, so compare both for your numbers before deciding.
When is the last date to file an ITR?
For most individual taxpayers who are not subject to audit, the due date has commonly been 31 July following the financial year, with later dates for audit and business cases. Due dates are sometimes extended by the department, so confirm the current year's deadline on incometax.gov.in rather than relying on last year's date.
What documents do I need to file my return?
Commonly: PAN and Aadhaar, Form 16 if salaried, bank and interest statements, capital-gains statements for any share or property sales, rent and home-loan details, and proofs of any deductions you plan to claim. Your Annual Information Statement on the portal is a useful cross-check.
Do I need to file if tax was already deducted (TDS)?
Often yes. TDS being deducted does not remove the obligation to file, and filing is how you claim a refund if excess tax was deducted. Filing also builds a clean income record that helps with loans and visas.
What happens if I file late or miss the deadline?
A belated return can usually still be filed for a limited window after the due date, but a late-filing fee and interest may apply, and some benefits — such as carrying forward certain losses — can be lost. It is better to file on time; if you have missed it, file the belated return promptly.
Is my PAN required to be linked with Aadhaar to file?
PAN and Aadhaar are required to be linked, and an inoperative PAN can create problems with filing and refunds. If yours is not linked because of a name or date-of-birth mismatch, resolve that first — see our PAN correction guide.
Can Harsiddhi Services file my return?
We assist with return preparation and filing — organising your documents, computing income under both regimes where useful, and filing on the portal. We give you a fixed quote before starting. Complex cases may need a chartered accountant, and we will tell you honestly when that is the case.
