    Question: I received 1099-NEC forms from several clients this year. How do I figure out how much I can contribute to my Solo 401k?

    Answer: The calculation starts with Schedule C, line 31:

    1. Add up every 1099-NEC received during the year.
    2. Report the total on Schedule C and subtract business expenses.
    3. Take the net profit on line 31 and subtract one-half of self-employment tax.
    4. Use the result to calculate employee and employer contributions.

    My Solo 401k Financial offers a contribution calculator and performs these calculations for clients as part of its ongoing support.
