## What the ITR Compliance API does

ITR Compliance returns the compliance position attached to a PAN: whether it is linked to Aadhaar, its current status, and its classification under Section 206AB.

The 206AB classification carries direct financial consequences. Non-filers attract TDS at a higher rate, and deducting at the wrong rate leaves the deductor exposed, which makes this a routine pre-payment check.

## Where teams use the ITR Compliance API

1.  Determining the correct TDS rate before a payment
    
2.  Checking PAN-Aadhaar linkage for compliance
    
3.  Screening vendors for non-filer status
    
4.  Avoiding short-deduction notices
    

## Frequently Asked Questions (FAQs)

What is Section 206AB?

A provision requiring higher TDS rates for specified persons who have not filed returns. The classification tells you which rate applies.

Why does Aadhaar linkage matter?

An unlinked PAN can become inoperative, which affects transactions and TDS treatment.

How often should I check?

Before significant payments, and periodically across your vendor base, since status changes as filings are made.
