Get your taxes done using TurboTax

The self employment taxes do show up on a separate line on your tax return.  But it is included in your refund or Tax due.  Self employment and schedule C is a disregarded entity and goes on your personal tax return.  If you have  a Net Profit on schedule C you get social security credit for it and can use it as income to contribute to a IRA.

Why do you think you want to file it separately?
