What is the alternative minimum tax from Form 6251?
Form 6251: Alternative Minimum Tax-Individuals is an Internal Revenue Service (IRS) tax form used to determine the amount of alternative minimum tax (AMT) that a taxpayer may owe. Some taxpayers with higher incomes can claim certain deductions that allow them to reduce their regular tax obligation.

Who Must File
Attach Form 6251 to your return if any of the following statements are true.
⦁ Form 6251, line 7, is greater than line 10.
⦁ You claim any general business credit, and either line 6 (in Part I) of Form 3800 or line 25 of Form 3800 is more than zero.
⦁ You claim the qualified electric vehicle credit (Form 8834), the personal use part of the alternative fuel vehicle refueling property credit (Form 8911), or the credit for prior year minimum tax (Form 8801).
⦁ The total of Form 6251, lines 2c through 3, is negative and line 7 would be greater than line 10 if you didn’t take into account lines 2c through 3.

Why was Alternative Minimum Tax Implemented?
Alternative Minimum Tax provisions were created in 1986 to create fairness in the Canadian taxation system. Its purpose was to prevent high-income earners and trusts from paying little to no tax because of various tax deductions and incentives.
Initially, individuals were only required to calculate tax liabilities under the regular method. With the introduction of AMT, taxpayers are now required to calculate their tax liabilities using both the AMT method and the regular method.

What Preferential Tax Items Trigger AMT?
Several items may trigger AMT, namely:
Capital gains
⦁ Dividends
⦁ Losses and deductions
⦁ Losses and deductions related to limited partnership interests and ⦁ tax shelters
⦁ Losses from resource properties
⦁ Stock option deductions
⦁ Deductions for employee home relocation loans
⦁ Federal political contribution tax credit
⦁ Investment tax credit
When an individual can claim the items, the AMT calculation is triggered to ensure that they are paying the minimum they owe in taxes to the government.
Purpose of Form
Use Form 6251 to figure the amount, if any, of your alternative minimum tax (AMT). The AMT is a separate tax that is imposed in addition to your regular tax. It applies to taxpayers who have certain types of income that receive favorable treatment, or who qualify for certain deductions, under the tax law. These tax benefits can significantly reduce the regular tax of some taxpayers with higher economic incomes. The AMT sets a limit on the amount these benefits can be used to reduce total tax.
Also use Form 6251 to figure your tentative minimum tax (Form 6251, line 9). You may need to know that amount to figure the tax liability limit on the credits listed under Who Must File, earlier.
Figuring AMT Amounts
For the AMT, certain items of income, deductions, etc., receive different tax treatment than for the regular tax. Therefore, you will need to figure items for the AMT differently from how you figured them for the regular tax. These instructions will help you figure AMT items by using the amount you figured for the regular tax and refiguring it for the AMT. In some cases, it is easiest to refigure an item for AMT by completing a tax form or worksheet a second time using additional AMT instructions. These instructions refer to such a form or worksheet as an “AMT” version. If you do complete an AMT version of a form or worksheet, don’t attach it to your tax return unless instructed to do so. For example, you may have to attach an AMT Form 1116, Foreign Tax Credit, to your return; see Line 8, later.
As you figure some deductions and credits for the AMT, carrybacks or carryforwards to other tax years may be different from what you figured for the regular tax. Examples are investment interest expense, a net operating loss, a capital loss, a passive activity loss, and the foreign tax credit. Your at-risk limits and basis amounts may also differ for the AMT.
Recordkeeping
You must keep records to support items reported on Form 6251 in case the IRS has questions about them. If the IRS examines your tax return, you may be asked to explain the items reported. Good records will help you explain any item and arrive at the correct AMT.
Keep records that show how you figured income, deductions, etc., for the AMT. Also keep records of any items that you used to figure the AMT that differ from what you used to figure the regular tax. For example, you will need to separately figure and track certain carrybacks, carryforwards, basis amounts, depreciation, and loss limitation amounts that differ between the AMT and the regular tax.
If you refigure an item for AMT by completing an AMT version of a form or worksheet, keep a copy of that AMT form or worksheet for your records.

How do you calculate your alternative minimum income?
Alternative Minimum Tax (AMT) is an alternative method to calculate the minimum amount an individual owes in taxes based on their income.
AMT Amount = A * (B – C) – D
A = 15%
B = the individual’s adjustable tax income.
C = $40,000, the AMT exemption amount.
D = Allowable non-refundable tax credits.
