Form 26AS is the tax credit trail
Form 26AS is commonly used to verify tax deducted, tax collected, advance tax and self-assessment tax. Mismatches usually need source-level checking with the employer, bank, deductor, challan or filing data.

Practical process before hiring
Compare source records
Match Form 16, Form 16A, challans and Form 26AS line by line.
Trace the deductor
Identify whether the issue is employer filing, bank TDS, challan CIN, PAN error or timing.
Plan correction
Ask the deductor to revise TDS return or correct challan details where required.
File with evidence
Prepare the ITR and keep proof ready if the credit is still under correction.
