You can put all your net earnings from self-employment in the plan: up to $12,500 (in 2015 - 2018), plus an additional $3,000 if you're 50 or older (in 2015 - 2018), plus either a 2% fixed contribution or a 3% matching contribution.
Additional note on Estimated Payments:
You may also calculate your estimated taxes from within the TurboTax software as well as prepare 1040-ES payment vouchers by following these TurboTax FAQ steps:
- "With your tax return open, search for 1040-es (be sure to include the dash) and select the “Jump to” link.
- Answer No to the question, Do you want to change your W-4 withholdings for 2018?
- On the next screen, Review Your Estimates, select Review Now.
- Proceed through the interview, answering questions about your 2018 filing status, income, deductions, etc.
- Eventually, you'll come to the Print Vouchers screen; answer Yes and we'll include your 2018 1040-ES payment vouchers when you print a copy of your return later.
Rest assured that TurboTax 2017 uses the 2018 tax rates recently passed by Congress and signed into law when calculating your 2018 estimated taxes."
