IRS Form 8804 (Schedule A) – IRS Forms, Instructions, Pubs 2026 – In the complex world of partnership taxation, especially for those with foreign partners, compliance with IRS withholding requirements is crucial. IRS Form 8804 Schedule A specifically addresses penalties for underpayment of estimated Section 1446 tax, which applies to effectively connected taxable income (ECTI) allocable to foreign partners. This form helps partnerships determine if they owe a penalty and calculate its amount, ensuring timely payments to avoid additional costs. If you’re managing a partnership with international elements, understanding this schedule can prevent unexpected IRS penalties and streamline your tax filing process.
What Is IRS Form 8804 and Schedule A?
Form 8804 is the Annual Return for Partnership Withholding Tax under Section 1446, used to report the total liability for withholding tax on ECTI allocable to foreign partners. Schedule A is an attachment to Form 8804 that focuses on penalties for underpaying estimated taxes. Partnerships must use it to assess:
- Whether they are subject to the underpayment penalty.
- The exact amount of any penalty owed.
This schedule is essential for partnerships that didn’t make timely installment payments of at least the smaller of the current year’s tax or a safe harbor amount based on the prior year. For the 2025 tax year, if the total Section 1446 tax is less than $500, you don’t need to complete or file Schedule A.
Section 1446 requires partnerships to withhold tax on ECTI distributed to foreign partners, similar to estimated tax payments for U.S. individuals. Failure to pay in four required installments can trigger penalties calculated under principles akin to Section 6655.
Who Must File Schedule A (Form 8804)?
Not every partnership needs to file Schedule A. Generally, it’s required if the partnership has ECTI allocable to foreign partners and didn’t meet the safe harbor for estimated payments. Key criteria include:
- Partnerships with foreign partners subject to Section 1446 withholding.
- Those that underpaid estimated taxes, meaning they didn’t pay at least the smaller of:
- The tax shown on line 5f of their 2025 Form 8804.
- The prior year’s (2024) Section 1446 tax, adjusted for certain conditions like it being at least 50% of the current year’s tax and covering a full 12-month period.
If your partnership checks the applicable boxes in Part I of Schedule A, you must attach it to Form 8804 and check line 8 on the main form. The IRS will automatically figure the penalty if Schedule A isn’t attached when required, potentially without considering exceptions.
Exemptions may apply for small partnerships or those with minimal withholding obligations, but always verify with the latest IRS guidelines.
How to Calculate the Underpayment Penalty?
Calculating the penalty on Schedule A involves several steps, drawing from Form 8804-W (Installment Payments of Section 1446 Tax for Partnerships) for estimating installments. Here’s a high-level overview:
- Determine Required Installments: Payments are due on the 15th day of the 4th, 6th, 9th, and 12th months of the tax year. Rates are typically 21% for corporate foreign partners and 37% for non-corporate ones, with adjustments for preferential rates.
- Check Safe Harbors: Avoid penalties by paying at least the prior year’s tax (line 2 of Schedule A) or the current year’s tax, whichever is smaller, provided certain thresholds are met.
- Account for Reductions: Include deductions for state/local taxes and certified partner-level items via Form 8804-C.
- Penalty Computation: Use the underpayment period to calculate interest-like penalties. Enter the total on line 8 of Form 8804.
For precise calculations, refer to the official instructions, as threshold amounts for penalties are adjusted annually for inflation. Tools like Form 8804-W can help estimate payments in advance.
| Key Line Items on Schedule A (Form 8804) | Description |

| Line 1 | Total Section 1446 tax from Form 8804, line 5f. |
| Line 2 | Prior year’s Section 1446 tax (safe harbor amount). |

Exceptions and Safe Harbors to Avoid Penalties
Schedule A includes provisions for exceptions, which the IRS won’t consider if the form isn’t filed. Common ways to mitigate or avoid penalties:
- Safe Harbor Rule: Pay 100% of the prior year’s tax if it meets the 50% threshold and was for a full year.
- Annualized Income Method: For partnerships with uneven income distribution.
- Reasonable Cause: If late filing or payment was due to unavoidable circumstances, penalties may be waived.
Always document your calculations, as the IRS may request supporting details.
Filing and Payment Requirements
File Form 8804 (with Schedule A attached if applicable) by the 15th day of the 3rd month after the tax year ends (e.g., March 15 for calendar-year partnerships). Electronic filing is recommended for efficiency. Penalties for late filing start at 5% of unpaid tax per month, up to 25%.
Payments can be made via EFTPS or other IRS-approved methods. For balances due, subtract credits from the total liability.
Recent Changes and Updates for 2025-2026
As of January 2026, instructions have been updated to remove static threshold amounts, directing users to IRS.gov/InflationAdjustment for annual adjustments. Form 8804 now includes expanded lines for direct deposit refunds (lines 14b-14d). Stay informed via IRS.gov for any legislative changes affecting Section 1446.
