Alternate minimum tax for limited liability partnerships requires adjusted total income taxed at specified rate when AMT exceeds regular tax Certain limited liability partnerships must, where alternate minimum tax exceeds regular income-tax, be treated as having total income equal to an adjusted total income (total income increased by specified deductions) and pay tax at the alternate minimum tax rate. A certified accountant's report must accompany the return. Excess AMT paid over regular tax is allowable as a tax credit, carried forward and set off subject to a ten-year carryforward limit and adjustment where assessments are varied.
