Filing a return: what the process actually asks of you

What the process is actually doing

Filing a return is not paying tax. It is declaring a year — every source of income, the tax already collected against it, and the difference. The department then processes that declaration, but only after you have separately confirmed, by a second act, that the declaration is yours.

Most of the tax has already gone by the time a return is opened. Payers withheld slices of it as they paid you, and instalments were due through the year on the income no payer could see. That machinery is set out in advance tax and TDS, and the return is what finally reconciles it.

Stripped of the software, the process asks five things of you in order. Assemble the year's income from every source, including the sources nobody reported. Sort it into the heads the law uses, because where income sits decides the rate it meets. Choose a form that has room for those heads. Set the computed liability against what has already been paid. Then authenticate the whole thing.

The arithmetic in the middle — heads, deductions, the slab ladder, the rebate, the order they come in — belongs to income tax, in the order it is actually computed. This page is about the four steps around it, which is where almost all of the trouble actually is.

Owing no tax and having to file are different questions

These get treated as one question, and they are decided by two different numbers. A person can owe nothing and still be required to file. A person can be outside the compulsory net and still be much better off filing. Both happen constantly.

The compulsory test asks whether your income crossed a stated threshold. The load-bearing detail is which income it measures. Historically the test has been applied to income before the deductions you claim and before the rebate that wipes out the tax — so the very reliefs that bring your bill to nil do not bring you below the filing line. The relief cancels the tax; it does not cancel the duty to file. That ordering is the mechanism to carry, and it is one to confirm for the year you are filing rather than carried over from last year.

Then there is a second family of triggers that has nothing to do with what you earned. Deposits above a size, spending above a size, turnover above a size — these attach to a transaction, and they can make filing compulsory for someone whose income never came close to the threshold. A retired person living off savings who moves a large sum through a current account is the recognisable case. So is anyone holding an asset abroad, which has historically carried its own duty to file regardless of income; settle that one for your year rather than guessing at it.

One more wrinkle catches people with equity. The default regime carries a rebate of up to ₹60,000 where total income does not exceed ₹12 lakh — but s.156(3) is explicit that the rebate cannot shelter special-rate income such as s.198 long-term capital gains. So a modest earner who sold units in March can owe real tax while believing their income level keeps them clear, and the same person is likely to believe filing is optional. The rates that produce that result are in capital gains tax explained.

Thresholds also differ by age, and the figures move with almost every Finance Act. No figure appears here for that reason. The shape of the test — two families of trigger, one keyed to income measured before your reliefs, one keyed to a transaction — is the part that survives the year; the amounts are published for the year you are in.

The larger group: people who need not file, and gain by it

Ask who is required to file and you get a list. Ask who is worse off for not filing and you get a longer one, because two things exist only if a return is furnished, and neither is obvious from the form.

A refund is a claim, not a repayment. Nobody at the department is holding money aside for you and waiting. Tax deducted on your interest by a bank that had no idea your income was below the taxable limit sits with the government as tax until a return says otherwise. There is no other instrument that says otherwise. A student, a retired parent with a deposit ladder, a person who worked for four months of the year — each is likely to have had too much withheld, and each of them recovers it by filing or not at all.

The second reason is less about tax than about evidence. A payslip is an employer's assertion about one relationship. A filed return is the only document that states your income, across every source, in your own name, to the state. That is why lenders sizing a loan and consulates assessing a visa ask for two or three years of them — not as bureaucratic habit, but because nothing else in an Indian household's paperwork does that job. What the lender does with it once received is a separate matter, covered in how lenders decide what you can borrow.

The consequence for the self-employed is sharper than for the salaried. No filing history is no income history. A consultant with three good years and no returns has nothing to show a bank except bank statements, which record receipts rather than income. The absence is not neutral at the moment it is asked about — it reads as an absence of evidence.

A third reason deserves naming and then leaving open. Carrying a loss forward, so it can be set against a future gain, has historically depended on the return being filed within the on-time window rather than late. If that condition survives, the deadline matters intensely to someone who owes no tax at all — the person least likely to be watching it. Settle it for your year before relying on either answer.

And the cost, because there is one. Filing takes an evening, and it starts a series. Once returns exist for two years, a gap in the third is itself a question — to a lender, and to the department's own matching. Beginning to file is a small commitment to keeping on, which is a real trade-off and not a reason against, only a thing to know before starting.

The form is a container shaped by your kinds of income

The commonest way to get a return wrong is to choose the form by how complicated you feel, or by what you used last year. Neither is the test. The form is decided mainly by which kinds of income you have, and a single new kind can move you.

The reason is structural. Income is sorted into heads before it is taxed — salary, house property, capital gains, business or profession, and everything else. The return forms mirror that sorting: the simplest one carries fields for a couple of heads and nothing else, and each step up adds schedules for the heads the previous form had no room for. Sell some fund units and you have created a head your form may have no page for.

A second condition sits alongside the first, and it is the one that surprises landlords. The simplest forms limit not only which heads they will carry but how many of some of them — a second let-out property does not create a new head, it exceeds a count inside the head that is already there. Same effect, different reason: the container no longer fits.

Now the consequence, which is the part that matters. A form with no schedule does not delete the income; it makes that income undeclared rather than absent, in a year where the department already has a third-party report of the same transaction. The mismatch is generated automatically and arrives later as a question, and by then the return has been processed on figures you did not intend.

So the thing that moves you up the series is mostly a change of kind, not a change of size. Another lakh of salary usually changes nothing about which form you file; a single ₹4,000 gain on a redemption can, because it is a different head altogether. Read that asymmetry as the working rule rather than the entire rule — the simplest form has historically carried an overall income ceiling too, so check the conditions attached to the form you are about to open.

The numbering of the forms is not stated here. It belongs to the notified utilities rather than to the Act, and the series is renotified often enough that reading it for the year you are filing beats carrying it over from memory.

One question decides how much of the container is even live: which regime the year is filed under. Under the default new regime there is no s.123 deduction with its ₹1.5 lakh cap, no s.126 relief of ₹25,000, raised to ₹50,000 where the insured is a senior citizen, and the salary standard deduction runs at ₹75,000 under the new regime and ₹50,000 under the old. House rent allowance belongs to the old regime only. A reader filling a deduction schedule under the default regime is filling pages that do not apply to them; the comparison is in the old regime against the new.

Pre-filled data is a claim about you, not a computation of you

The return arrives partly populated, and the populated part looks authoritative because it came from the department. Be precise about what it actually is. It is an assembly of what third parties reported about you: employers, banks, registrars, brokers, tenants, fund houses. Long known as the annual information statement and the tax credit statement — the AIS and Form 26AS, though the names are worth confirming for the year you are filing — it is built from duties other people had, not from a computation of your tax. Which of those documents holds what, and where each one under-counts, is worked through in Form 16, Form 26AS and the AIS.

That single fact fixes exactly how it is wrong, and this is the part people miss. Its errors are directional, not random. A proof-reader looks for typos, which are random. This document has a systematic blind spot and a systematic over-statement, and knowing which is which tells you where to look.

It is blind to income nobody had a duty to report. Rent below the size at which a tenant must withhold — that duty runs at 2% where monthly rent exceeds ₹50,000 — arrives whole, with no report behind it. Cash receipts, a private loan's interest, small professional fees below a payer's threshold: none of them appears, and their absence looks exactly like an empty field.

It over-states wherever a reporter knew the gross figure and not the net. The clearest case is a sale of shares or fund units. The registrar reports what left the scheme; it has no idea what you paid for the units, because cost of acquisition lives in your records and nowhere else. Read carelessly, a redemption of ₹6 lakh looks like ₹6 lakh of income when the gain might be ₹40,000. Interest on a joint deposit is the same species of error — often reported in full against one holder, because the bank reports against the first name rather than against the arrangement.

So checking the pre-fill is not proof-reading. It is supplying the half of the picture that nobody else was in a position to see, and then answering the entries that are there but wrong. There is generally a route for recording that an entry does not belong to you or is overstated. An entry left unanswered stays on the record as a reported figure, and reported figures are what the matching runs against.

Two of those checks need dates and prices rather than judgement: which units were bought when, and at what. The holding period at 12 months decides whether a gain meets s.196 at 20% or s.198 at 12.5% above ₹1.25 lakh in the year, and units of a fund that is mostly debt, bought on or after 1 April 2023, sit outside both: s.76 taxes them at slab rates, with the gain always treated as short-term. None of that is in the pre-fill, and all of it changes the number.

Filing and verifying are two acts, and the second is the one people drop

Submitting a return produces an acknowledgement number and a page that reads like completion. It is not completion. Verification — the step that authenticates the submission as yours — is a separate act, taken separately, and until it happens the return has not been taken up.

Three things are routinely thought of as one event, and they are not.

Look at the failure row. Two of the three failures announce themselves eventually: an empty schedule produces a question, a mismatch produces an intimation. The middle one produces nothing. There is no bounce, no rejection, no error — the submission sits exactly where it was left, and the artefact in your inbox is indistinguishable from the artefact a completed filing produces.

The unverified return is the silent failure. It is discovered months later, by a refund that never arrives or a lender who cannot find the year. Several routes exist to verify, most of them electronic and immediate, one of them physical and slow; a window applies, and what happens when it closes is the question to settle rather than test. The habit that removes the whole failure mode is small: treat the acknowledgement number as a receipt for an upload, and go looking for the separate confirmation that verification is done.

What the calendar does, stated without the dates

No date appears in this section. Filing dates get extended, moved and occasionally restored inside a single season, so a date carried over from an article written last year is the one thing here most likely to be wrong. The shape of the rule generalises, and it survives every Finance Act.

There is an on-time window, whose closing date differs for a taxpayer subject to audit and one who is not. There is a later window in which a return can still be filed and a stated fee attaches. There is a further window for correcting or belatedly declaring, which generally costs more the longer it is left. And running underneath all three, interest on tax still unpaid, charged for the period the money was late.

Three properties of that structure carry across years, and none needs a date.

• Lateness has a second price. The fee is the visible part. Interest on unpaid tax runs from the instalment checkpoints inside the year, not from the filing deadline, which is why a return filed late on tax that was never paid carries a bill built up over months — the mechanism is in advance tax and TDS.
• Rights close with the window. If carrying a loss forward depends on filing on time, then a taxpayer with no liability at all can lose something real by being late. That is the case where the deadline binds hardest on the person watching it least.
• A route, not a rescue. A filed return can generally be put right, but the routes narrow and get more expensive as the year recedes. Discovering an omission early is worth materially more than discovering the same omission later, and that ordering does not depend on any particular date.

Whether the department pays anything for holding a refund, and whether that entitlement changes if the return went in late, is a separate question to settle for your year. Money handed over early and reclaimed at filing has sat with the government in the meantime, and that is a cost whether or not it is compensated.

Six failures, each traceable to one of the steps above

1. Reading the pre-fill as computation. It is an assembly of what other people reported. It cannot see the income nobody reported, and it reports gross where only you know the cost.
2. Reusing last year's form. The form follows kinds of income. One redemption, one second let-out property, one foreign holding, and the container that fitted last year has no page for this year.
3. Nil tax, assumed nil duty. The compulsory test has historically been applied to income before the deductions and the rebate that reduce the tax to nothing.
4. Stopping at the acknowledgement. The number is a receipt for an upload. Verification is a second act and it fails silently.
5. Skipping the return after over-withholding. Excess tax deducted is not refunded by anybody's initiative. The claim is the return.
6. Leaving a wrong entry unanswered. A reported figure that does not belong to you does not lapse from being ignored; it stays on the record the matching runs against.

Four of the six — the first, third, fifth and sixth — come from one belief: that the system already knows and will sort itself out. It knows what it was told, by people who were told to tell it. Everything else in your year reaches it through you or not at all.

The part of this that is a records problem

Notice how little of the above is judgement. Almost all of it is facts about your own year, and the facts people reconstruct worst in filing season are the ones a gain computation starts from: which units were bought, on what date, at what price, and which of them were sold.

That is precisely the information the pre-fill cannot hold. FNOTrader's Mutual Funds app runs on the full published history of daily per-unit scheme values from AMFI — the net asset value, or NAV — around 34 million rows of it, and for any scheme and period reports invested amount against value alongside the return on cashflows landing on irregular dates, which is XIRR. It does not compute anybody's tax and it does not file anything. What it holds is the dated, priced record that a capital-gains figure has to begin from — and in filing season it is that record, not the rate, that people cannot rebuild.

Nothing here is tax advice, and FNOTrader is not a chartered accountant, a tax practitioner or a SEBI-registered investment adviser. The dates, fees, thresholds and form numbers change every year; the structure — two tests for who files, a form chosen by kind of income, a pre-fill that errs in known directions, and a second act that completes the first — is what carries between years.
