Form 26AS and AIS: How to Reconcile Your Tax Credits Before Filing

Every taxpayer eventually discovers that the number they expect to see in their return and the number the tax department already has on file aren't automatically the same thing. Form 26AS and the Annual Information Statement (AIS) are the two places that record what the department knows about your income and the tax already paid on it, and filing without checking both against your own records is how a mismatch turns up later as a notice instead of a quiet correction. Both statements are freely available on the income tax e-filing portal, updated through the year as deductors and reporting entities file their own returns, and both are worth a proper look well before the deadline rather than a rushed glance on the last day. Here's what each one actually shows, and how to reconcile them before you file rather than after.

Form 26AS: Your Tax Credit Ledger

Form 26AS is the narrower and older of the two statements, and it's specifically about tax already paid on your behalf or by you: TDS deducted by your employer, bank, or clients; TCS collected on purchases or foreign remittances; advance tax and self-assessment tax you've paid yourself; and any refund already issued. It's organised into distinct parts by type of credit - salary TDS, other TDS, TCS, taxes you've paid directly, and refunds - so you can go straight to the part relevant to your situation instead of scanning one long list. Every entry is tied to your PAN and shows the deductor's or collector's TAN, the section under which tax was deducted, and the amount involved. This is the document the tax department's own processing system checks against the credit you claim in your return, which makes it the one statement you genuinely cannot afford to skip, no matter how thoroughly you've been through AIS.

AIS: The Bigger Financial Picture

AIS goes well beyond tax already paid. It pulls together most of what's reported to the department about your financial life during the year - salary, interest from savings accounts and fixed deposits, dividends, mutual fund and securities transactions, property purchases and sales, foreign remittances under LRS, and more - sourced from banks, registrars, employers, and other reporting entities, in addition to the same TDS/TCS data that appears in 26AS. The statement itself is split into a general profile section and a detailed, category-wise transaction section, which makes it easy to jump straight to the part you actually need to check rather than wading through everything at once. Alongside it sits the Taxpayer Information Summary (TIS), a simplified, category-wise summary derived from AIS that's used to pre-fill parts of your return. TIS is convenient, but it inherits whatever errors exist in the underlying AIS entries, so treat it as a starting draft rather than a verified figure.

How to Reconcile Before You File

1. Download both statements from the income tax e-filing portal: Form 26AS through the 'View Form 26AS' link, which routes to TRACES, and AIS through the separate 'Annual Information Statement' service.
2. Match every TDS/TCS line in Form 26AS against the certificates you actually hold - Form 16 from your employer, Form 16A from banks or clients, or the certificate for any property or rent-related deduction - checking the amount, section, and deductor details.
3. Cross-check AIS entries for interest, dividends, and mutual fund or securities transactions against your own bank statements, annual interest certificates, and consolidated account statements.
4. Check any foreign remittance or property entry in AIS against your own remittance receipts or sale/purchase deed, since these are often the entries with the highest amounts and the most room for error.
5. Note anything that looks off - a missing TDS entry, a duplicated interest report, income that isn't actually yours - before you start filling in the return itself, and use TIS only as a pre-fill starting point, not a verified number.
6. If you're self-employed or a freelancer, also add up TDS deducted by each client individually and check it against the total shown in 26AS - a single missing client is often the entire gap.

Fixing a Mismatch

The fix depends on which statement has the problem. If Form 26AS is missing a TDS entry you know was deducted, the cause is almost always on the deductor's side - a late or incorrect TDS return, or occasionally a deduction made so close to year-end that it simply hasn't been processed yet - and only the deductor can correct it by revising their filing; your job is to chase them with the certificate and challan details, not to simply wait it out. If an AIS entry is wrong - duplicated, mis-attributed, or just inaccurate - you can submit feedback directly against that entry from within AIS, choosing the reason that fits, and that response becomes part of your record even if the underlying report doesn't change immediately. Keep whatever evidence supports your position; it's what you'll point to if a query comes in later.

Reconciling both statements takes an hour or two if you've kept your certificates and bank documents organised through the year. Skipping it doesn't make a mismatch disappear - it just moves the conversation to after you've filed, when it arrives as an automated notice instead of a checklist you worked through calmly at your own pace.
