US Tax & Compliance

US tax and compliance. For startups operating in the US

US startups face a growing list of federal, state, payroll, and corporate filing requirements. We keep every obligation on one calendar, assign clear ownership, and make sure filings are handled accurately and on time.

What a missed filing can cost

Form 5472

$25,000

Initial penalty per required form, per tax year, for late, missing, or substantially incomplete reporting of qualifying related-party transactions.

Form 5471

$10,000

Initial penalty for failure to meet applicable foreign corporation reporting requirements. Additional penalties may apply.

Delaware Franchise Tax

$200 + 1.5%/mo

Late filing or payment penalty, plus monthly interest on unpaid taxes and penalties. Delinquency can affect the company's good standing.

Missing a filing can be expensive even when the underlying tax liability is zero.

The return is only as good as the books it comes from.

A tax firm sees

  • Your books once a year, at filing time
  • Whatever made it into the ledger
  • Whatever the bookkeeper happened to know

The team that keeps your books sees

  • The hire in a new state, the month it happens
  • The customer that crossed a sales threshold
  • The loan from the parent
  • The payroll that triggers a state registration

The miss isn't on the preparer's desk. It lives in the gap between the preparer and whoever kept the books.

Here, the same team does both.

One calendar with every deadline and its owner.

One named person who replies within a business day.

CFO supervision and review from day 1 of your compliance posture.

Federal, state, entity, cross-border. All of it, on one calendar.

Your list is set in writing in week one. Everything below is inside the Starter, Scale, or Soar scope on the pricing page.

Asked about US tax on most first calls.

The US company has its own returns: federal, state, Delaware, and the 5472 that reports the link to the parent. Most home preparers don't file them, and most US preparers never see the intercompany side.
