Dear Liz: I am a freelancer. I don’t consider myself a small-business owner, just someone who gets the work done on time and gets paid. I max out my IRA every year, but would like to save more in a tax-advantaged account.

I checked out SEP and SIMPLE IRAs, but they don’t have a Roth option. Am I eligible to start an Individual 401(k)? What administrative duties would be involved? I pay self-employment tax and my clients send me 1099s, not W2s.

Answer: You may not consider yourself a small-business owner, but that’s essentially what you are. And small-business owners should have tax pros to help them answer questions like this, since you have so many options.

As a sole proprietor, you should be able to set up a solo or individual 401(k) account. That would allow you to make either pre- or after-tax “employee” contributions of up to $18,000 in 2015 — plus an additional $6,000 if you’re 50 or older.

As your own employer, you can contribute an additional 25% of your net earnings (a contribution that would be deductible as a business expense). Your total contribution, employee plus employer, can’t exceed $53,000 in 2015.

Individual 401(k)s are somewhat more complicated to set up and administer than Simplified Employee Pensions (SEPs) or Savings Incentive Match Plan for Employees (SIMPLEs). But many discount brokerages are eager to help you with the paperwork and have low or no set-up costs.

You have many other ways as a self-employed person to reduce your taxes, but the rules can be complicated. A certified public accountant or an enrolled agent can help advise you of your options.
