What does Northwest Registered Agent do for you?#
Northwest Registered Agent offers registered agent service, LLC/corporation/nonprofit formation, annual report filing, EIN service, business address service, legal document templates such as operating agreements and bylaws, and free identity/privacy tools with domain, website, email, and phone add-ons. Its positioning emphasizes privacy and service quality.
The facts file describes Northwest as a nationwide formation and compliance-filing company, not a tax-preparation firm, with a long track record and privacy-and-service-quality positioning.
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.
| Task | Northwest Registered Agent | Form5472 Prep |
|---|---|---|
| LLC formation | Formation filings | Complete federal package |
| Registered agent | Registered agent service | Federal filing only |
| EIN | EIN service | Collects LLC facts |
| Form 5472 package | Points readers to CPA | Generates federal package |
| IRS fax filing | Not offered as a paid service | Ogden fax receipt |
| Catch-up for missed years | DIIRSP if prior years were missed | DIIRSP catch-up route |
Northwest points readers to a CPA instead of filing it#
The facts file says Northwest's own Form 5472 blog post is explanatory: it covers what the form is, who must file, and Form 5471 versus Form 5472. It ends by telling readers that, to determine whether Form 5472 is necessary, it is a good idea to check with a CPA.
The same facts file says no reviewed Northwest page offers to prepare or file Form 5472 or a pro forma Form 1120 as a paid service. That is a neutral scope line: Northwest handles formation and registered-agent work; the Form 5472 filing is separate.
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.
An accountant 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 Northwest-formed 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?
The facts file says no reviewed Northwest page offers Form 5472 or pro forma Form 1120 preparation or filing. Its own Form 5472 article sends readers to check with a CPA.
- 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.
- Northwest 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.
- Why might Northwest source URLs show 403 in command-line checks?
The facts file says Northwest's site-wide WAF returns 403 to curl and non-browser requests, including the homepage, while the listed URLs were separately verified live in a browser on 2026-08-28.
