Real problems. Documented results.

Anonymized, representative engagements from our CPA & EA team — the problem, the work, and the numbers at the end.

Every situation below is a pattern we see weekly. Details are anonymized; the outcomes are the kind our clients hire us for.

US Tax FilingCASE 01

Three missed Form 5472s — $75,000 in exposure, fully waived

The problem. A non-resident e-commerce founder discovered Form 5472 existed when an IRS notice arrived. Three back years unfiled, $25,000 penalty exposure per year.

What we did. We prepared all three delinquent pro-forma 1120/5472 filings, built the transaction schedules from bank records, and filed reasonable-cause statements with each year.

Resale CertificateCASE 02

Amazon seller with nexus in 11 states, untangled in one engagement

The problem. A growing FBA seller had crossed economic and inventory nexus thresholds in nearly a dozen states without registering anywhere — liability accruing silently.

What we did. We ran a full nexus study, registered in the states that mattered, secured resale certificates, and set the ongoing filing calendar alongside monthly bookkeeping.

US Tax FilingCASE 03

Two years of wrong S-corp returns, amended — and the fee paid for itself

The problem. A service business owner came from a big-box chain that had mishandled his S-corp salary and distributions two years running.

What we did. We amended both years, restructured a defensible reasonable salary, and set up clean payroll going forward.

US GAAP AdvisoryCASE 04

Cash-basis startup books rebuilt to GAAP in time for a seed round

The problem. A SaaS founder's data room was blocked on financials: cash-basis books, no revenue recognition, investor diligence waiting.

What we did. We converted the books to accrual, implemented ASC 606 revenue recognition, and produced investor-ready statements with monthly close thereafter.
