US LLC tax filing, handled
We prepare the federal filing a foreign-owned single-member LLC needs, including Form 5472 and the pro-forma Form 1120, from the records you share.
$399 per filing for a single-member LLC. A C-Corp is $899; a multi-member LLC is $899 ($1,500 late).
Form 5472 and the pro-forma Form 1120 are filled in from your records, you sign the marked page by hand and upload it, and the return is faxed to the IRS with a confirmation received.
Which filing your company needs
Ownership and tax classification decide the forms. We confirm yours before any work starts.
Single-member LLC, one non-US owner
Usually files Form 5472 with a pro-forma Form 1120 when it had reportable transactions with its owner.
A single-member LLC owned by one person is a disregarded entity for US tax. When it is foreign-owned, the IRS treats it as a corporation only for Form 5472 reporting, and the form is attached to a pro-forma Form 1120.
Multi-member LLC, all members foreign individuals
Files a partnership return (Form 1065) with a Schedule K-1 for each member. We file it when every member is a foreign individual and the LLC has no US business income.
We add Schedule B-1 and Schedules K-2 and K-3 where they are required, name our partnership representative on the return (you accept that before you pay), and print and mail the return to the IRS. We offer tax years 2023, 2024 and 2025. We do not file it for an LLC with US business income, a member that is a company, trust or US person, or an amended partnership return.
C-Corporation
Files Form 1120, and Form 5472 for each foreign related party it transacted with.
The owner's own return: Form 1040-NR
Form 1040-NR is your personal US return as a nonresident, filed only when you personally have US-source income or income effectively connected with a US trade or business.
It is separate from the company's filing. When your single-member LLC has US business income (effectively connected income), we prepare your Form 1040-NR with its schedules together with the company filing, included in the single-member LLC price. With an ITIN we send it after you sign; without one we also prepare Form W-7 to apply for it, and you mail that package to the IRS yourself. For other personal US income we do not prepare a return; we tell you if your situation points to one, so you can ask a tax adviser.

Deadlines you should know
The return is due on the fifteenth day of the fourth month after the tax year ends: April 15 for a calendar year. A Form 7004 extension moves the filing deadline, not any payment. We file Form 7004 for you for $99 per company per tax year, included in Full Compliance, if you order it before the original due date.

Filing, explained
Does my LLC have to file if it earned nothing?
Possibly. A foreign-owned single-member LLC files Form 5472 for any year with reportable transactions, including money you put in or took out. No revenue does not by itself remove the requirement.
How is the filing submitted, and what do I receive?
We prepare the forms and submit them to the IRS. You receive copies of everything filed and a record of the submission. The IRS processes returns on its own schedule and does not issue an acceptance letter for Form 5472.
Is the price per year or per filing?
Per filing. A single-member LLC return is $399; a C-Corp return is $899. A multi-member LLC return is $899, or $1,500 once it is late. Full Compliance subscribers have federal filing included in their plan.
What if I already missed the deadline?
Tell us before you do anything else. We can still prepare the filing. Without a Form 7004 on file by the original due date it is priced as a late filing, $750 for a single-member LLC and $1,500 for a C-Corp or a multi-member LLC, and where relevant we help you request penalty relief. Contact us with the tax year and your situation.
Do you file the Form 7004 extension for me?
Yes. We prepare Form 7004 and send it to the IRS for $99 per company per tax year, included in Full Compliance. Order it on the Federal tax page before the original due date (April 15 for a single-member LLC or C-Corp, March 15 for a multi-member LLC); the IRS does not accept it after that, so file the return as soon as you can, or upload the confirmation if you or your preparer already filed it. No signature is needed: we fax or mail it and keep the fax confirmation or mailing receipt as your proof. It adds six months to file, not to pay any tax owed. With it on file the filing keeps its normal price; without it, a filing after the original due date is a late filing, $750 for a single-member LLC and $1,500 for a C-Corp or a multi-member LLC.
Do you file state returns too?
One Wyoming or Delaware state return is included with the C-Corp filing when the state requires one. Other state work is quoted separately.
Do I need bookkeeping first?
You need a clear record of the year’s transactions. Bank statements are often enough for a low-activity LLC. Our accounting service can prepare reconciled books if you would rather not do it yourself.
What counts as a reportable transaction with the owner?
Money or property moving between you and the company: capital you put in, expenses you paid for it, amounts it paid you, loans in either direction and their repayment. Form 5472 reports these by category, which is why we ask for them separately from revenue.
Can you prepare returns for earlier years I never filed?
For a single-member LLC with no U.S. business activity we prepare tax years 2023, 2024 and 2025. A year past its due date is filed at the late price ($750); we note the late filing where the form requires it and, where it applies, prepare a penalty-relief request with the filing. For a C-Corp we prepare tax year 2025 ($1,500 once it is late). For a multi-member LLC whose members are all foreign individuals with no US business income we prepare tax years 2023, 2024 and 2025, each at the late price ($1,500). An earlier year needs a tax professional who prepares it by hand.
