Most retirees who consult don't realize they can still shelter income in a retirement plan.
If you earn self-employment income, even part-time, you're likely eligible. There's one catch: your Schedule C has to show a profit. No profit, no contribution.
Once you're in the black, the options open up. A Solo 401(k) lets you contribute as both the employee and the employer, up to $72,000 in 2026, $80,000 if you're 50-plus, and weirdly, $83,250 between 60-63. That's a real tax deduction on consulting income you may not need day-to-day.
If your consulting practice really takes off, defined benefit plans go even further. It's not uncommon to fund those with a few hundred thousand dollars per year over about five years. That's a big lever for deferring taxes into later, hopefully lower, tax years.
The deduction is nice today. But you want to make sure you're not creating a bigger problem when the money comes out. Are you setting up future RMDs (required minimum distributions) that actually result in a bigger tax hit?
If you're doing any paid work in retirement, what does your Schedule C look like this year?
