What's included
The full return calendar for a US business, plus the cross-border filings most preparers miss.
- Federal returns: 1120, 1120-S, 1065
- State income and franchise tax filings
- Sales tax registration and filings
- Payroll tax compliance
- Forms 5472 and 5471 for cross-border ownership
- Extensions and estimated tax payments, tracked and filed on time
A foreign-owned single-member LLC must file Form 5472 annually. The automatic penalty for missing it is $25,000. Cross-border ownership always changes the filing picture. We map it before it bites.
