GST ITC Reversal Rules — When and How to Reverse Input Tax Credit

Input Tax Credit (ITC) under GST must be reversed in several situations — when goods/services are used for exempt supplies, personal use, or the credit is otherwise ineligible. Failure to reverse ITC correctly leads to interest at 18% per annum and penalties. Here is a complete guide to ITC reversal rules under GST.

Section 17(5) — Blocked Credits (Non-Reversible, Simply Ineligible)

These credits cannot be availed at all (not a reversal — simply ineligible from day one):

• Motor vehicles (cars, motorcycles) — for personal or employee transport
• Food, beverages, outdoor catering — unless the taxpayer is in the same business
• Health services, membership of club/fitness centre — for employees
• Travel benefits — air travel, hotel for personal purposes
• Works contract for construction of immovable property (except for further supply of works contract)
• Construction of own immovable property — blocked for the buyer/company

Rule 42 — ITC Reversal for Mixed Supplies (Inputs and Input Services)

• When a registered person uses inputs and input services for both taxable and exempt supplies: ITC must be apportioned
• ITC attributable to exempt supplies must be reversed
• Formula: ITC to reverse = Total ITC × (Value of Exempt Supplies / Total Turnover)
• Provisional reversal done each month; final reversal calculated annually and adjusted in March return
• Common examples: Hospitals selling medicine (taxable) and providing medical services (exempt); real estate developers (exempt completed flats + taxable commercial)

Rule 43 — ITC Reversal for Capital Goods Used in Mixed Supplies

• Capital goods used for both taxable and exempt: Credit must be spread over 60 months (5 years)
• Monthly proportionate amount for exempt use must be reversed each month during the 60-month period

GSTR-2B Mismatch — Reversal for Supplier Non-Filing

• ITC on invoices not appearing in GSTR-2B cannot be availed — if the supplier has not filed their GSTR-1, the credit does not appear in buyer's 2B
• Rule 37A: If the supplier does not file GSTR-3B for the relevant period, the buyer must reverse the ITC (with interest from the date of availing) — and re-claim when supplier eventually files

Reversal on Cancellation of Registration / Non-Payment to Supplier

• If payment to supplier is not made within 180 days of invoice date — ITC availed must be reversed (Rule 37) with interest at 18%
• ITC can be re-claimed once payment is made
