9. Try a Solo 401k
You can still participate in a retirement plan if you're self-employed. Legally, as long as you have self-employment income, you're entitled to establish and contribute to a solo 401k plan, which the IRS calls a one-participant 401k plan.
The good news about a solo 401k plan is that as both an employer and an employee, you're allowed to make both types of contributions. For the 2018 tax year, this means that you can contribute $18,500 as an employee — assuming you earn at least $18,500 — and up to 25 percent of your compensation as an employer. So, if you earned $40,000, you could contribute $18,500 as an employee and $10,000 as an employee for a total contribution of $28,500.
