GST Refund Time Limit
& Maximum Refund Calculation
Section 54 ยท Rule 89(4) Formula ยท S.54(3) Allowed ยท S.54(10) Withheld ยท DBK Exception ยท Practical Calculation
Two of the most misunderstood concepts in GST export refunds: When can you claim? (Time Limit โ Section 54) and How much can you claim? (Maximum Refund โ Rule 89 Formula). Most exporters assume they can claim their entire ITC as refund. That is wrong. The law caps your refund based on a formula โ and missing the time limit permanently bars your claim.
