IRS Form 8827 – Are you a corporation navigating the complexities of alternative minimum tax (AMT) credits? IRS Form 8827 is your key tool for reclaiming taxes paid in prior years. In this comprehensive guide, we’ll break down everything you need to know about IRS Form 8827, including eligibility, step-by-step filing instructions, recent updates, and tips to maximize your credit for prior year minimum tax – corporations. Whether you’re preparing your 2025 tax return or reviewing past liabilities, understanding Form 8827 can help reduce your current tax burden and optimize your corporate finances.
What Is IRS Form 8827?
IRS Form 8827, titled Credit for Prior Year Minimum Tax – Corporations, allows corporations to calculate and claim a credit against their current year’s tax liability for AMT paid in previous years. This credit helps offset the financial impact of the corporate AMT, which ensures that corporations pay a minimum level of tax despite deductions and credits that might otherwise reduce their regular tax to zero.
The form also determines any unused credit to carry forward to future years, providing ongoing relief. It’s particularly relevant for corporations subject to the corporate alternative minimum tax under Internal Revenue Code (IRC) Section 59A, known as the base erosion and anti-abuse tax (BEAT). By filing Form 8827, eligible corporations can recover excess taxes paid, improving cash flow and tax planning strategies.
Who Needs to File Form 8827?
Not every corporation files Form 8827—it’s specifically for those with a history of AMT liability. Here’s who qualifies:
- Corporations with Prior-Year AMT: If your corporation incurred alternative minimum tax in any prior tax year, as reported on Form 4626 (Alternative Minimum Tax – Corporations), you must use Form 8827 to compute the available credit.
- Applicable Corporations Under Section 59A: Businesses subject to the new corporate AMT (base erosion minimum tax) can claim credits for prior-year minimum tax using this form.
- C Corporations Filing Form 1120: This form attaches directly to your U.S. Corporation Income Tax Return (Form 1120), reported on Schedule J, line 5d.
S corporations and partnerships generally don’t file Form 8827, as AMT rules differ for pass-through entities. Always consult IRC Section 55 for AMT applicability.
Eligibility Requirements for the Minimum Tax Credit
To claim the credit on Form 8827, your corporation must meet these criteria:
- Prior AMT Liability: You need an outstanding AMT amount from a previous year, pulled from Form 4626, Part II, line 13.
- Current-Year Limitation: The credit is limited to the excess of your current regular tax liability (plus any base erosion minimum tax) over allowable non-refundable credits.
- Ownership Change Considerations: If your corporation experienced a Section 382 ownership change, credits may be limited under Section 383. Similarly, Section 384 restricts pre-acquisition excess credits from offsetting built-in gains.
- No Refundability: This is a non-refundable credit, meaning it reduces your tax bill to zero but doesn’t generate a refund. Excess carries forward indefinitely.
Eligibility ensures the credit targets corporations that overpaid due to AMT, promoting fairness in the tax code.

Key Calculation Tips
- Credit Amount: It’s the lesser of your prior AMT (line 3) or the current-year limitation (line 10).
- Allocation Methods: For ownership changes, use ratable allocation or the closing-of-the-books method per Treas. Reg. §1.382-6.
- Software Integration: Tax preparation software like TurboTax Business or professional tools automate these calculations, pulling data from Form 4626.
Double-check entries against your records to avoid IRS notices.
