How much do other firms charge for business tax preparation?
Other firms usually charge $800 to $2,500 for a CPA-prepared S corporation return, and complex multi-state returns can pass $5,000. C corporation returns run in a similar range. CPAs who bill by the hour usually charge $150 to $450 an hour, so disorganized records push the bill up fast.
Korven's returns start from books that are already reconciled, so nobody bills you to rebuild them in April.
Who prepares and files the return?
Korven prepares your books and tax file; our licensed CPA partner prepares, signs and files your return. Korven itself is not a CPA firm. You get one team for the books and one licensed signature on the return. See what our tax preparation and filing service covers.
What changes the price of a business tax return?
Five things change the price of a business tax return:
- The type of entity: sole proprietor, partnership, S corporation or C corporation.
- How many owners need a K-1.
- How many states you file in.
- Assets, rentals or other extra schedules.
- How clean the books are. If they are not tax-ready, catch-up bookkeeping comes first, at $250 per month behind.
How much do 1099s cost?
