Reducing Your Tax at $75K: Key Strategies
A Solo 401k is particularly powerful at $75,000. As both employee and employer, you can contribute up to $23,500 (employee contribution) plus 25% of net SE income (employer contribution) = approximately $16,000, total up to $39,500 — far exceeding what an IRA allows. This contribution reduces your net SE income, which reduces both SE tax and income tax.
