If you’re a small business owner, it’s important to plan for tomorrow. SEP Individual Retirement Accounts (IRAs) are popular among business owners with no employees, and the self-employed who want to save more. You may contribute as much as 25 percent of your net earnings (up to $54,000) in 2017. Another option if you're self-employed, or if your spouse is your only employee, is a solo 401(k), which allows you to stash the same percentage of earnings and to defer up to $18,000 of your salary annually. If you don't have employees, you might prefer an SEP, which gives you until April 15 to make contributions for the previous year, and has a percentage contribution formula, which benefits those with higher incomes. An SEP, like a 401(k) and an IRA, can also help lower your tax burden in areas with high rates, like New York and California.
