A correctly filed return with a refund due should process smoothly. When it doesn't, the cause is almost always one of these — worth checking before you file, not after you're wondering where your refund went.
Bank account not pre-validated
Refunds are only credited to a bank account that's pre-validated on the income tax e-filing portal, with your PAN linked to it. This is the single most common reason a refund shows as "processed" but never arrives — the return is fine, the payment simply has nowhere to go.
Mismatch between Form 26AS/AIS and what you've declared
If the TDS or income figures in your return don't match what's reflected in Form 26AS or the Annual Information Statement, the system flags it for review before releasing any refund. This is especially common when income from multiple employers or multiple bank accounts isn't fully reconciled.
Return filed but not verified
Filing and verification are two separate steps. A return that's filed but not e-verified (or verified late) doesn't enter processing at all — from the department's side, it's incomplete. This is an easy one to miss since the portal shows the return as "submitted."
Outstanding tax demand from a previous year
If there's an unresolved demand from an earlier assessment year, the current year's refund can be adjusted against it — sometimes without much visible warning. Checking your portal for old outstanding demands before filing avoids this surprise.
Incorrect or outdated personal details
A mismatch in name, address, or a bank account that's since been closed can all stall processing. These sound minor, but they're a disproportionately common cause of "stuck" refunds.
The practical takeaway
Most of these are checkable in five minutes before you file: pre-validate your bank account, reconcile against Form 26AS/AIS, verify immediately after filing, and check for old demands. Catching them upfront is far faster than chasing a delayed refund afterward.
If you'd rather have someone check all of this for you, get in touch before you file.
