IRS Form 8804W is for Installment Payments of Section 1446 Tax for Partnerships. It helps partnerships determine required installments, and the form requires consideration of netting rules under section 1(h) and Notice 97-59.
Plain English
This form allows a partnership to spread out its tax payments throughout the year instead of paying one lump sum at the end. By using methods like annualized or adjusted seasonal installment calculations, the partnership can adjust its required payment amounts based on when it expects most of its income to be earned. This helps manage cash flow and meet IRS obligations.

Quick Facts

What do I enter on Line 12 of Form 8804-W?
This line requires entering any 2025 overpayment credited against the 2026 tax, along with specific withheld/paid amounts.
→ Ensure you include Section 1446 tax withheld by another partnership (if applicable) and payments for U.S. real property or partnership interests.
Do I need to fill out all three parts (II, III, and IV)?
If both the adjusted seasonal installment method and the annualized income installment method are used, all three Parts must be completed.
→ Check which methods you employ before filling out the form.
Where do the de minimis extraordinary items go?
Items totaling $1 million or more from a transaction or section 481(a) adjustment should go on line 22b for the appropriate period, but if they are chosen to be *excluded* from line 15, they must still appear on line 22b.
→ Refer to the 'Extraordinary items' section of the instructions for precise placement.
How do I determine which installment columns (a-d) to use?
Columns (a) through (d) on line 30 correspond to the annualization periods used when calculating the ECTI allocable to all foreign partners on lines 31a through 31e.
→ Confirm your chosen annualization method dictates these specific columns.
What is the difference between Line 22b and Line 15?
Line 15 requires certain extraordinary items, while line 22b includes those same items if they are $1 million or more from a transaction/section 481(a) adjustment OR if the partnership chooses to exclude them from line 15.
→ Check the instructions for 'Extraordinary items' to confirm inclusion rules.
What is the required minimum threshold to file Form 8804-W?
A partnership must generally make installment payments of estimated section 1446 tax if the aggregate tax on the ECTI allocable to all foreign partners will be $500 or more.
→ Verify your total projected ECTI tax meets this $500 threshold.

This form allows a partnership to spread out its tax payments throughout the year instead of paying one lump sum at the end.

This helps manage cash flow and meet IRS obligations.
Partnerships are the filer category that uses IRS Form 8804W to report their installment payments for Section 1446 tax.
The form collects details on required installments, which are calculated using methods detailed in Part II and/or Part III. It also captures amounts of tax withheld from a disposition of an interest under section 1446(f)(1) during the installment period.
For calendar-year taxpayers, the due dates are the 15th day of the 4th, 6th, 9th, and 12th months; for fiscal-year taxpayers, these correspond to their partnership's tax year. If a regular due date falls on a Saturday, Sunday, or legal holiday, the next business day is used.
The form does not specify a single service center address but requires calculation based on installment periods corresponding to when payments were made or withheld. The use of this Form 8804W is optional for aiding the partnership in determining its tax liability.
The partnership must complete Part II and/or Part III to calculate installments; if both are used, all three Parts must be completed. For each installment period, Line 43 requires entering the smaller amount between line 39 or line 42. The final required installment total is entered on line 11.
If line 7 on an installment payment is smaller than line 8, and that smaller line 7 amount is entered on line 9, the partnership may not qualify for the prior-year safe harbor when calculating penalties due on Schedule A (Form 8804).
This line requires entering any 2025 overpayment credited against the 2026 tax, along with specific withheld/paid amounts. Ensure you include Section 1446 tax withheld by another partnership (if applicable) and payments for U.S. real property or partnership interests.
