The issue is not sales. The issue is delivery, specifically Section 1446 withholding, Form 8804 reconciliation, and getting Forms 8805 out on time without swallowing partner review hours. That is exactly where our team steps in.
At Accountably, we build and run disciplined offshore delivery for U.S. firms, so you keep control of workflow, quality, and security while expanding capacity for tax, advisory, and audit work. We work inside your systems, your templates, and your deadlines. You stay in charge. We handle the grind.
Key takeaways
- You file Form 8804 to reconcile Section 1446 withholding on ECTI and transmit duplicate Forms 8805 for each foreign partner. Calendar-year filers are due March 15. Form 7004 extends filing, not payment.
- Section 1446 installments are due in months 4, 6, 9, and 12. Pay by EFTPS or with Form 8813, then reconcile on Form 8804 and furnish 8805 to each foreign partner.
- Notify foreign partners within 10 days after each installment due date or payment, so they can manage their own estimated tax.
- Schedule A computes underpayment penalties and supports safe harbors and annualization when income is uneven.
- Accountably integrates trained offshore teams into your firm with SOPs, structured workpapers, review layers, and security controls, so Form 8804 delivery stops bottlenecking partner time and client trust.
Who we help
- CPA firms and EA practices that serve partnerships with foreign partners and need reliable 8804, 8805, 8813, and Schedule A execution.
- Multi-entity and multi-state firms that want standardization across tax, accounting, financial advisory, and audit support.
- Growing firms that want advisory time back while raising delivery quality and protecting margins.
Why Form 8804 work breaks firms
The mechanics look simple, yet the calendar punishes small misses. Quarterly cash timing, ECTI allocations, safe harbor choices, and 8805 credit matching all collide in review. Without structure, partners end up in loops, staff rush workpapers, and foreign partners wait on credits. Growth stalls because delivery becomes the ceiling.
How Accountably fixes the delivery ceiling
- Capacity without chaos, using planned utilization and turnaround SLAs.
- Workflow discipline, with SOPs for tax prep, workpaper naming, version control, and reviewer protection.
- Review protection, through a multi-layer review model and standardized schedules that cut partner time.
We are not a staffing body. We build and operate a controlled offshore delivery system that you can scale with confidence.

What is Form 8804
Form 8804 is the partnership-level annual return that reports the partnership’s Section 1446 withholding tax on ECTI allocable to foreign partners. You file it as the control return, attach a duplicate Form 8805 for every foreign partner, and pay any balance due after installments. Calendar-year partnerships file by March 15. If books and records are kept outside the United States and Puerto Rico, the due date shifts to the 15th day of the sixth month.
Form 8804, 8805, and 1042 at a glance
| Item | What it covers | Who files | When it is furnished or filed |
| Form 8804 | Annual partnership return reconciling Section 1446 withholding on ECTI | Partnership | 15th day of the 3rd month after year end, or 6th if books kept abroad |
| Form 8805 | Partner statement showing ECTI and Section 1446 withholding credit | Partnership issues to each foreign partner, attaches duplicates to 8804 | Furnish by the partnership return due date, including extensions |
| Form 1042 | Annual return for Chapter 3 FDAP withholding, not ECTI | Withholding agent | Separate regime from Section 1446 |
Who must file and when it applies
If your partnership has ECTI allocable to foreign partners, you must make estimated payments if annual Section 1446 tax will reach at least $500, then file Form 8804 with duplicate Forms 8805 for each foreign partner. Installments are due by the 15th day of months 4, 6, 9, and 12 of the partnership tax year.
Triggers and obligations
| Trigger | Your obligation |
| ECTI allocable to foreign partners | Make required installments and file Form 8804, issue all Forms 8805 |
| Distributions that cause Section 1446 withholding | Remit and report, then reconcile on 8804 |
| Expect at least $500 Section 1446 tax | Pay quarterly installments using EFTPS or Form 8813 |
Key deadlines and extensions
- File Form 8804 by the 15th day of the third month after year end. If books and records are outside the United States and Puerto Rico, the due date is the 15th day of the sixth month. Weekends and federal holidays push to the next business day.
- Use Form 7004 for more time to file. The extension does not extend time to pay. Pay any expected Section 1446 balance with the extension or via electronic methods to limit penalties and interest.
- Furnish each foreign partner’s Form 8805 by the partnership return due date, including extensions, and attach duplicates to the filed 8804.
What this means for your workflow
You are managing two clocks at once. First, a quarterly payment clock that requires cash planning and partner notifications. Second, an annual return clock that demands ECTI support, allocation proof, and clean partner statements. Accountably designs your calendar and workpapers around both, so reviewers see answers, not questions.
Estimated payments and installment schedule
Section 1446 uses a pay-as-you-go model. For most partnerships, each installment is 25 percent of the required annual amount, due on the 15th day of the 4th, 6th, 9th, and 12th months, adjusted to the next business day when needed. If income is uneven, annualize or use the adjusted seasonal method to keep penalties down.
EFTPS or Form 8813
You can transmit Section 1446 installments electronically through EFTPS or mail a payment with Form 8813. If you use EFTPS, you still file Forms 8804 and 8805 to reconcile and allocate. EFTPS availability for these payments is now confirmed in IRS guidance.
- Plan early for EFTPS access, since enrollment and mail-confirmation steps can take time, especially close to deadlines.
- Keep confirmation numbers for every electronic payment and map them to workpapers.
- If you file Form 7004, pay any expected Section 1446 balance with the extension to curb penalties.
10-day partner notifications
Notify each foreign partner within 10 days after the installment due date, or within 10 days of payment if you pay later. This confirms the amount paid on their behalf so they can manage their own estimated tax. We template these notices, tie them to your ECTI allocations, and archive them for audit readiness.
Schedule A and underpayment penalties
Schedule A computes penalties when installments are missed or underpaid. Safe harbors matter. You can base required installments on the prior year or on the annualized current year. If you pick a smaller current-year safe harbor when it undercuts the prior-year amount, the prior-year safe harbor will not protect later periods, and recapture may apply. We model both tracks and prepare catch-up payments to reduce exposure.
Practical guardrails we use
- Build a quarter-by-quarter matrix that shows required installments, credits, and timing, then lock it for review.
- Tie ECTI, adjustments, and applicable rates to a clearly labeled partner tab.
- Recompute in real time when allocations change and run a penalty preview before each due date.
- Document any Form 8804-C reliance and attach required statements so reductions are supported.
Coordination between 8805 and K-1
Form 8805 is the authoritative credit record. Schedule K-1 must align on ECTI and allocations, but it does not replace 8805. We match names, TINs, and amounts, verify totals to Form 8804, and deliver partner copies on time to prevent credit mismatch notices.

FAQs
What is Form 8804 used for
It is the partnership-level return that reconciles Section 1446 withholding on ECTI and transmits duplicate Forms 8805 for each foreign partner. It is due the 15th day of the third month after year end for calendar-year filers, typically March 15.
How do Form 8804 and Form 8805 work together
You reconcile annual withholding on 8804 and furnish 8805 to each foreign partner to claim the credit on their own return. Totals on all 8805 forms must tie to 8804.
Can we pay Section 1446 installments through EFTPS instead of mailing 8813
Yes. You can transmit payments through EFTPS. Keep confirmations and still file 8804 and 8805.
What happens if we miss an installment
Schedule A computes an underpayment penalty from the due date until paid. Annualization and safe harbors may reduce or remove penalties when income is uneven.
When do foreign partners get notified about installments
Notify them within 10 days after the installment due date, or within 10 days of payment when later, so they can manage their estimated tax.
