GSTR-3B Working Paper Guide

What a professional GSTR-3B working paper should contain.

A GSTR-3B working paper should not be only a tax total sheet. It should explain output liability, input tax credit, reverse charge, reversals, reclaim, payments and variances with source data.

See GCRS Software Request Demo

Output tax working

Start from the sales register and classify outward supplies into taxable, zero-rated, nil/exempt, non-GST and RCM-related buckets where applicable.

ITC working

Use books, GSTR-2B and ITC claim tracking to prepare 4A ITC available, 4B reversal, 4C net ITC and 4D other ITC disclosures.

RCM working

Reverse charge liability and related eligible ITC should be visible separately so it does not distort regular output and input tax review.

Variance review

Compare books working with portal draft or filed 3B data. Keep manual adjustments documented with remarks and supporting schedules.

FAQ

Common questions

Why should GSTR-3B working include source data?

Source data helps reviewers verify how each return figure was calculated and supports audit or future query handling.

Can GSTR-3B be prepared only from GSTR-2B?

No. GSTR-3B also needs books output liability, RCM, reversals, reclaim and other business-specific adjustments.

What is a good variance review?

A good review compares books, portal/draft and final return figures and explains any material difference.
