USA · CORPORATE SERVICES
Monthly maintenance for US LLC and C-Corp. Annual report filing, registered agent renewal, compliance monitoring, and corporate documents. From $350/month. Fully remote.
What we handle
US states impose ongoing compliance obligations. Missed filings result in loss of good standing, which can block bank account applications, payment processor approvals, and contract enforceability.
Annual report filing
All states
LLC and C-Corp annual reports filed across all 50 states. Deadlines tracked and filed by MOSTAR without reminders needed from you.
Registered agent
$150/yr
Required in the state of incorporation. Receives legal and government correspondence on behalf of the company. Included in maintenance plan or $150/yr standalone.
Delaware franchise tax
Optimized
MOSTAR calculates both the authorized shares method and assumed par value method, and files using the lower amount. Saves hundreds for typical C-Corps.
Corporate documents
On request
Board resolutions, written consents, operating agreement amendments, officer appointments, and share certificates. Included in the maintenance plan.
Good standing certificate
When needed
Required for bank account opening, investor diligence, and some payment processor approvals. Obtained same-day for most states.
Compliance monitoring
Ongoing
Filing deadlines, fee renewals, and state law changes tracked on an ongoing basis. Advance notice before any action is required.
