Books and filing under one roof
One flat price for your annual return — company or individual. Prepared with AI, reviewed and signed by a licensed CPA. The complex cross-border forms most software quietly skips are handled here too.
Upload statements and prior returns; our AI extracts and organizes everything.
The return is drafted by AI and reviewed line by line by a licensed CPA.
You review, we e-file federal and state, and you get the signed copy.
These aren’t just forms — they’re where a complex case gets expensive. We price them explicitly and file them every week. Genuinely complex cases are quoted on a consultation.
Foreign-owned or foreign-holding structures. Miss one and the penalty is $10K–$25K, automatic, and it stacks every year. We file these every week.

Every state you touch is another rulebook — Wayfair, registration, apportionment. We map where you owe across all 50.
Yes — one flat price for the standard annual return either way. Genuinely complex returns (heavy cross-border, many states) carry add-ons, shown below.
Cross-border forms like 5471 / 5472 / FBAR, QSBS §1202 work, and multi-state apportionment. These are priced as add-ons or quoted on a consultation.
A licensed CPA reviews and signs every return. AI does the preparation; a person stands behind the filing.
