Frequently asked questions

A licensed US CPA on our in-house team prepares, reviews, and signs your return. You'll have a named CPA in your dashboard for the entire tax year.

Yes. Foreign-owned single-member LLCs must file Form 5472 with a pro forma 1120 even with zero activity. Missing it triggers a $25,000 penalty. Starter covers exactly this case.

Form 5472 is required for US entities with 25%+ foreign ownership that had any reportable transaction — including capital contributions. If you're a non-US founder with a US LLC or C-Corp, you almost certainly need it.

Yes. We handle catch-up filings for prior tax years and, where applicable, request penalty abatement from the IRS. Priced per year based on complexity.

You can bring your own books or add North Filings bookkeeping. Either way, we review the books before filing to catch issues that would slow the return.
