AMT credit allows carryforward and set-off against future tax, with exclusions for certain special tax regimes. Tax credit under Section 115JD allows carryforward and set-off of AMT paid in excess of regular income-tax against future tax liability, with any excess foreign tax credit (allowed against AMT but exceeding that admissible against regular tax) ignored for computing the credit. No interest is payable on the credit. The credit is utilisable where regular tax exceeds AMT in a later year, with balance carried forward, and will be adjusted if regular tax or AMT is varied by any order under the Act. Certain taxpayers under specified tax regimes are excluded from these provisions.
