Your US LLC's tax return, filed every year
One member or several — we prepare the return the IRS expects from your LLC, an Enrolled Agent reviews and signs it, and we file it with proof of filing. You answer a plain-English questionnaire; you never touch an IRS form.
Reviewed & signed by an Enrolled AgentWhich return does your LLC file?
It depends on how many members (owners) the LLC had during the year.
Single-member LLC
- What is filed
- Pro forma Form 1120 + Form 5472 (reportable transactions with you, the foreign owner)
- Due date (calendar year)
- April 15 · extension to October 15 with Form 7004 (included)
- How it reaches the IRS
- By fax to the IRS line for foreign-owned single-member LLCs, with a transmission report
- If it's late or wrong
- $25,000 penalty per Form 5472
Multi-member LLC (partnership)
- What is filed
- Form 1065 + a Schedule K-1 for every member, plus Schedule B-1 and the foreign-partner forms when they apply (K-2/K-3 notice, 8804/8805)
- Due date (calendar year)
- March 15 · extension to September 15 with Form 7004 (included)
- How it reaches the IRS
- By USPS Certified Mail — the IRS doesn't take Form 1065 by fax; the postmark is your filing date
- If it's late or incomplete
- $255 per member, per month (up to 12 months)
Penalties: IRC §6038A(d) for Form 5472; Instructions for Form 1065 (2025), “Late Filing of Return”, for Form 1065. LLC elected to be taxed as a corporation (Form 8832 or 2553)? That's a different return — tell us in the form below.
1. Questionnaire
Members and their shares, money in and out of the LLC, bank statements. About 10 minutes for a single-member LLC, a bit more with several members.
2. We prepare, you sign
The complete return — and each member's K-1 for a multi-member LLC — reviewed by an Enrolled Agent, sent to you for review and signature.
3. Filed with proof
Faxed (Form 5472) or mailed USPS Certified (Form 1065) to the right IRS office, with the transmission report or tracking kept for you.

Questions
Does my LLC have to file if it had no income?
Single-member LLC owned by a non-US person: yes, whenever there was any reportable transaction with you — even paying the formation fees or opening the bank account with your money counts. Multi-member LLC: Form 1065 is required unless the LLC had no income and no deductible expenses at all for the year.
Why is Form 1065 mailed and not faxed?
The IRS lists only mailing addresses (or e-file) for a paper Form 1065 — there is no fax line for it. We send it USPS Certified Mail; under IRC §7502 the postmark date is your filing date.
Do foreign members need an ITIN?
Each member's Schedule K-1 must show that member's taxpayer identification number — for a non-US individual that is usually an ITIN. Zeros or a blank field are not accepted. If a member has none, we tell you how to apply before the due date.
What does the price include?
The questionnaire, preparation of the return (and every K-1), review and signature by an Enrolled Agent, the Form 7004 extension if you need more time, and filing with proof. The price grows only with the number of members or unusual transactions — you get a fixed quote before we start.
Our LLC went from one member to two during the year.
Then the year is split: a single-member period and a partnership period, each with its own reporting. Tell us the date the new member joined — we'll quote both parts.
