Form 5472 + 1120 filing service
Used Northwest Registered Agent? Form 5472 is a separate federal filing.
A registered agent receives legal papers and official state notices for your LLC; it does not by itself file federal information returns. If Northwest Registered Agent formed or serves your foreign-owned single-member LLC, Form 5472 + pro forma Form 1120 is a separate annual IRS package, so confirm in writing whether any service you bought covers it.

What does Northwest Registered Agent do for you?
#As its name says, Northwest Registered Agent is a registered agent company. A registered agent accepts service of process and official state notices for your LLC. Northwest's plans and prices are not summarized here; check Northwest's own site or your invoice for what your order includes, including any tax filing service.
What does Northwest Registered Agent leave with you?
#A foreign-owned single-member US LLC must file Form 5472 with a pro forma Form 1120 annually when it has reportable transactions. This is true even when a registered agent or formation company handled the state filing, EIN service, business address, or annual report.
Form 5472 is federal tax information reporting. Registered-agent service and state compliance filings do not by themselves complete the federal IRS package.

How do you confirm whether Northwest covers Form 5472?
#Ask Northwest in writing whether any service on your account prepares and files Form 5472 with a pro forma Form 1120 for a specific tax year. Registered agent and state compliance work does not by itself complete the federal package, so a written answer tied to your invoice settles the question.
If the answer is no, or you cannot confirm coverage for past years, you can prepare and fax the package yourself or use a Form 5472-specific filing service.
What is your first-year filing timeline?
#The first filing year is the year the LLC was formed, even if formation happened late in the year. If the LLC had any reportable transaction during that partial year, Form 5472 + pro forma Form 1120 is due the next filing season.
For most foreign-owned LLCs, the owner-funded startup deposit into the LLC bank account is reportable. Revenue is not required for a first-year filing obligation to exist.
How do we file it?
#Our 12-question wizard collects the LLC facts, foreign-owner facts, year-end totals, and transactions between the LLC and related parties. We generate the complete federal package: pro forma Form 1120, Form 5472, supporting statement, cover letter, and reasonable cause statement if late.
A tax accountant who holds an IRS Preparer Tax Identification Number (PTIN) reviews each package before submission. We fax the signed return to the IRS Ogden PIN Unit at +1-855-887-7737 and provide the timestamped fax receipt. 100% money-back guarantee if we fail to submit.
How do you catch up on multiple missed years?
#If your LLC has been around for multiple years and the 5472 package was never filed, DIIRSP is the usual voluntary catch-up route when the IRS has not already contacted you. That means filing the missed-year packages together with a reasonable cause statement requesting penalty relief.

Frequently asked questions
- Does Northwest Registered Agent prepare Form 5472?
Check with Northwest directly. Registered agent and state filing services do not by themselves complete the federal Form 5472 + pro forma Form 1120 package. Ask Northwest in writing whether anything on your account covers it, for which tax years and at what price.
- Is a registered agent responsible for my federal Form 5472?
No. Registered agent service receives legal and state correspondence; it does not automatically prepare federal information returns. The foreign-owned LLC owner remains responsible for Form 5472 when required.
- My registered agent got my EIN. Is that different from Form 5472?
Yes. EIN service obtains the LLC's IRS identification number. Form 5472 + pro forma Form 1120 is the annual federal package that reports related-party transactions.
- Where does the Form 5472 package go if I file it myself?
The IRS Form 5472 instructions direct a foreign-owned disregarded entity to send Form 5472 with a pro forma Form 1120 by fax to the Ogden PIN Unit at +1-855-887-7737 or by mail. Keep the fax receipt or mailing record as evidence of transmission.
