Partnership return flow (Form 1065)

How a multi-member foreign-owned LLC reports and passes income through to its partners.

  1. Confirm 2+ members

    A multi-member LLC defaults to partnership treatment.

  2. Prepare Form 1065

    Report partnership income, deductions, and allocations.

  3. Issue Schedule K-1s

    Each partner gets a K-1 with their distributive share.

  4. Handle withholding

    Foreign partners may trigger Form 8804/8805 withholding.

Key Takeaways

  • Returns filed in 2026: $255 per partner for each month or part of a month late, capped at 12 months; $260 for returns filed in 2027.
  • Late Schedules K-1 add separate section 6721 and 6722 information-return penalties.
  • Rev. Proc. 84-35 relief excludes partnerships with nonresident-alien partners, so it does not help foreign-owned LLCs.
  • First-time abatement and documented reasonable cause are the abatement routes that work, and both require the return to be filed first.
  • With a valid Form 7004, the clock starts September 16, 2026; without one it has run since March 16, 2026.

How the penalty is computed

Section 6698 imposes a penalty when a partnership files Form 1065 late or files it without required information. For returns filed in 2026 (tax year 2025) the inflation-adjusted amount is $255, multiplied by the number of persons who were partners at any time during the year, for each month or part of a month the return is late, up to 12 months. Two partners filing four months late owe $2,040. Two partners filing a full year late owe $6,120. The amount rises to $260 per partner per month for returns filed in 2027 (tax year 2026). Because the penalty is per partner, not per return, it scales with headcount rather than with income, which is why a dormant LLC can owe thousands on a return that reports zero.

A second penalty rides along: late K-1s

Separately, section 6722 penalizes a failure to furnish each partner's Schedule K-1 on time, and section 6721 penalizes late filing of the K-1s with the IRS. These are information-return penalties with their own per-form amounts and their own reasonable-cause standard. When a Form 1065 is late, the K-1s are usually late too, so the total exposure is larger than the section 6698 figure alone. Filing the complete package at once, with the K-1s attached and copies furnished to the partners the same day, closes both clocks.

Why Rev. Proc. 84-35 does not rescue foreign-owned LLCs

The small-partnership relief many U.S. advisers cite, Rev. Proc. 84-35, treats a domestic partnership of 10 or fewer partners as having reasonable cause if every partner is a natural person (other than a nonresident alien) or an estate, every partner's share of each item is the same, and each partner timely reported their share. The nonresident-alien exclusion is the problem: a partnership whose partners are foreign individuals living abroad does not qualify, no matter how small it is. Do not send an abatement request that relies on it.

What does work: first-time abatement and reasonable cause

First-time abatement is an administrative waiver the IRS grants to a taxpayer with a clean compliance history: no penalties of the same type in the prior three tax years, all required returns filed, and any tax paid or arranged. It applies to the section 6698 failure-to-file penalty and is requested by phone or letter after the return is filed and the notice arrives. Reasonable cause is the statutory route: a written explanation of facts showing ordinary business care and prudence, for example reliance on documented professional advice, serious illness, or inability to obtain records, supported by dates and evidence. The strongest position is always the same: file the complete return first, then request abatement citing the filed return. An unfiled return has no abatement path.

Stopping the clock before September 15, 2026

For a calendar-year 2025 partnership with a valid Form 7004 extension, the penalty clock has not started yet and does not start until September 16, 2026. Every month saved after that is $255 per partner. The ForeignLLCTax Multi-Member LLC package prepares the complete Form 1065 and K-1s for paper filing, including the foreign-partner no-TIN statement and the K-2/K-3 exception notices, and its instructions have you mail by certified mail so the dated receipt proves a timely filing. If your extension was never filed, the clock has been running since March 16, 2026; file now, then request first-time abatement with the notice in hand.

Frequently Asked Questions

Is the penalty per return or per partner?

Per partner, per month. A two-partner LLC filing three months late owes 2 × 3 × $255 = $1,530 for returns filed in 2026.

Does a zero-income return still get penalized?

Yes. Section 6698 does not depend on income or tax due. The penalty applies to any required Form 1065 filed late.

Can we just not file and rely on the no-filing exception?

Only if the partnership truly neither received gross income nor paid or incurred any deductible or creditable amount for the year. If a member paid state fees or formation costs, that is a fact-specific question; filing the all-zero return is the safer route.

How do we request first-time abatement?

After the return is filed and the CP notice arrives, call the number on the notice or write to the address on it, state that you are requesting first-time abatement under the IRS administrative waiver, and confirm the three-year clean history. Keep proof of the filed return.
