Form 6251: Alternative Minimum Tax—Individuals
Checklist for 2016 Tax Year
Form 6251 calculates AMT liability when your regular tax under the federal tax system falls below the tentative minimum tax. For the 2016 tax year, inflation-adjusted exemption amounts and Schedule A rules affected how itemized deductions factored into alternative minimum tax calculations for individual taxpayers.
Step-by-Step Guide to Completing Form 6251 for the 2016
Tax Year
Step 1: Confirm AMT Filing Requirement Using 2016 Exemption Thresholds
Determine whether your regular tax liability calculated on IRS Form 1040 may fall below your tentative minimum tax. For 2016, the exemption amount depends on filing status and taxable income.
The AMT exemption amount equals $53,900 for single filers and heads of household, $83,800 for married filing jointly or qualifying widow(er), and $41,900 for married filing separately. Use your completed 2016 return to estimate this amount before deciding whether Form 6251 applies.
Income exceeding specific thresholds established by filing status triggers the exemption's gradual phase-out. Taxpayers with higher taxable income, especially those claiming certain tax benefits, often must complete this calculation. Understanding your filing status early supports accurate tax planning and helps prevent unexpected tax liabilities during the filing process.
Step 2: Gather Schedule A Information and Identify Disallowed Deductions
Collect your 2016 Schedule A to review itemized deductions claimed for the tax year. The alternative minimum tax requires you to adjust or disallow certain deductions when computing alternative minimum taxable income.
SALT deductions for state, local, and property taxes are not permitted in AMT calculations for
2016. Medical expenses, charitable deductions, and investment interest require separate treatment under AMT rules.
Review each deduction carefully to identify tax preferences that increase AMTI. Home equity loan interest, miscellaneous itemized deductions, and some personal exemptions may not reduce AMT exposure. Maintaining complete records improves clarity and ensures that Form
6251 reflects accurate adjustments without altering fact-checked amounts already reported.
Step 3: Calculate Alternative Minimum Taxable Income Using Form 6251
Part I
Complete IRS Form 6251 Part I to calculate alternative minimum taxable income from adjusted gross income. Add back disallowed itemized deductions, such as SALT deductions, miscellaneous itemized deductions, and certain home equity loan interest amounts.
Depreciation must be recalculated for property placed in service after 1998 using methods required under AMT rules rather than regular tax depreciation schedules. Depreciation adjustments apply to specific property categories and service dates, such as tangible property placed in service prior to 1999 and Section 1250 property.
Property placed in service after 2015 that did not claim special depreciation allowance does not require an AMT adjustment. Complete all required lines in Part I before applying the AMT exemption.
Step 4: Apply 2016 AMT Exemption Amount Based on Filing Status
Enter the correct 2016 AMT exemption amount in Form 6251 Part II based on filing status. The exemption amount reduces AMTI before the tentative minimum tax applies.
Married filing separately taxpayers face the lowest exemption and the earliest phase-out threshold, which increases AMT exposure compared with other filing statuses. Calculate any required phase-out by reducing the exemption when AMTI exceeds applicable income thresholds.
This step directly affects whether the alternative minimum tax applies. Accurate application ensures consistency with the 2016 tax law and avoids overstating or understating tax liabilities related to the exemption amount.
Step 5: Complete AMT Tax Calculation Using 2016 Tax Rate Tables
Calculate the tentative minimum tax in Form 6251 Part III using the two-tier AMT tax rates in effect for 2016. Apply the lower rate to income within the initial bracket and the higher rate to amounts above that threshold.
Taxpayers with higher AMTI must use the Form 6251 worksheet to compute accurate tax amounts. Enter the calculated tentative minimum tax on the appropriate line.
This figure represents the tax before comparison to the regular tax liability. Maintaining alignment with 2016 tax rates is essential, since later tax reform proposals and the Tax Cuts and
Jobs Act do not apply to this tax year.
Step 6: Compare Tentative Minimum Tax to Regular Tax Liability
Compare your tentative minimum tax with your regular tax liability reported on Form 1040. If it does not exceed the regular tax, no alternative minimum tax applies for the year.
When the tentative minimum tax surpasses the regular tax, the alternative minimum tax is the difference. Record this amount clearly on Form 6251 Part III.
This comparison ensures compliance with tax law and confirms whether AMT affects your final tax obligation. Proper documentation supports future use of AMT credits and reduces the risk of calculation errors.
Step 7: Address Qualified Dividends and Capital Gains in AMT Context
Identify qualified dividends and net capital gains reported on your 2016 return, including amounts from Schedule D. These income items receive preferential tax rates but require special handling under the alternative minimum tax framework.
Form 6251 includes a worksheet to calculate tax on these items accurately. Complete the worksheet when qualified dividends or capital gains apply.
The calculation ensures that preferential tax rates integrate correctly into the tentative minimum tax. Proper reporting avoids overstating tax and preserves consistency between regular tax and
AMT calculations.

Step 8: Carry Forward Unused AMT Credit to Future Years if Applicable
If Form 6251 shows alternative minimum tax for 2016, you may qualify for an AMT credit in later tax years. The credit becomes available when the regular tax exceeds the tentative minimum tax. The credit carries forward indefinitely until fully used.
Document the AMT amount carefully for use on Form 8801 in future years. Accurate tracking supports long-term tax planning and helps recover prior AMT paid without altering reported amounts from the original tax year.
