How long do tax filings take?
Tax filing timelines depend on when you complete the intake and how complex your return is.
Standard annual filing
After you pay and complete the Fill Forms intake in the Tax Center:
- Intake review — the preparer reviews your submitted details
- Draft preparation — typically within a few business days for straightforward foreign-owned LLC returns
- IRS submission — filed on your behalf once the preparer confirms accuracy
- Confirmation — you receive notice when filing is complete
OtoCo does not publish a fixed SLA, but most single-member Form 5472 / 1120 filings move quickly once intake is complete.
Catch-up filings
The 2024 Catch-Up Filing ($499 one-time) follows the same flow. Prior-year returns may take slightly longer if the preparer needs additional clarification.
What slows things down
- Incomplete intake forms — fill out every required field
- Missing entity details (EIN, legal name, ownership percentages)
- Complex multi-member cap tables without clear ownership records
Order early
U.S. federal returns for LLCs are generally due by March 15 (multi-member) or April 15 (single-member, with extensions available). Order from the Tax Center well before the deadline.
