GOODS AND SERVICES TAX RULES, 2017 - MISMATCH FORMATS

Goods and Services Tax mismatch formats categorise invoice matches to determine ITC allowance and resulting tax liability. Mismatch formats categorise invoice, debit and credit note matching into accepted ITC, mismatches/duplicates causing immediate liability increases, mismatches/duplicates causing future liability increases, and potential mismatches that may increase liability if not rectified; they tie each category to the originating document month, statutory return-filing deadlines and the treatment of reversal claims under Section 42/43, including disallowance, recovery, refund of ITC and interest adjustments.
