(Wall Street Journal) — JANUARY: Max those savings! Financial planners argue you should be saving 15% or more of your income each year. Set your 401(k) contributions to the highest level you can handle. At least contribute up to any company match, and ideally push the limits — $16,500 if you’re under 50, $22,000 if you’re over. If you are self-employed, or have self-employment income, talk to a broker about special tax-savings vehicles open to you, including Solo 401(k) plans, SEP-IRAs and Keoghs.
