Form 4626, officially known as the Alternative Minimum Tax — Corporations, is used by corporations to compute their Alternative Minimum Tax (AMT). This form is essential because it ensures that corporations with significant income do not escape tax liabilities by using exclusions, deductions, and credits available under the regular tax system. The AMT serves as a parallel tax calculation that overrides traditional income tax calculations if the AMT amount is greater, thus requiring corporations to pay the higher of the two.
Corporations use the 2015 Form 4626 to report taxable income adjustments and preferences. This includes changes necessary for AMT due to limitations and exclusions. Corporations begin by calculating their regular taxable income, and then make adjustments for AMT purposes, reporting these changes on various lines within Form 4626. The form ultimately computes the corporation's AMT liability, determining the additional tax owed beyond regular tax obligations, if applicable.

The Internal Revenue Service (IRS) is the issuing body for the 2015 Form 4626. It controls the guidelines and instructions for proper completion of the form, ensuring that corporations meet federal tax obligations appropriately.
Corporations failing to comply with AMT regulations face penalties and interest charges. Non-compliance includes underpayment due to incorrect calculations, failure to file by the deadline, or neglecting to pay taxes owed. Penalties are calculated based on the amount of tax underpaid and the length of the delay.
Example 1: Tech Corporation
Example 2: Mining Company
Understanding these practical applications helps corporations prepare and submit more accurate filings to the IRS, ensuring compliance and avoiding costly penalties.
