Many employers require you to use up the money in your FSA by December 31 or lose it (although more companies now offer a grace period to March 15, so ask your employer for its deadline).

If you have any self-employment income -- for example, you own your own business or earn freelance income on the side -- you can make tax-deductible contributions to a small-business retirement plan. You have several options, but depending on your income, a solo 401(k) may provide the highest contribution limits. You can contribute up to $17,000 plus up to 20% of your net self-employment income, up to a maximum of $50,000 in 2012. And you can add an extra $5,500 if you’re 50 or older. Your total contributions cannot exceed your self-employment income for the year. You must open a solo 401(k) by December 31, but you have until April 15, 2013, to make your 2012 contributions. See How the Self-Employed Can Save for Retirement for more information. Advertisement Contribute to a 529 college-savings account.

See Rules for Deducting 529-Plan Contributions for more information about qualifying for the deduction, whether you’re a parent, grandparent, other relative or even a friend.

After you turn age 70½, you must take required minimum distributions from your traditional IRAs and your 401(k) accounts (although there are some exceptions if you’re still working for the employer who sponsors your 401(k) plan). You have until April 1 to take your first RMD, but you must make your required withdrawals by December 31 every year after that.
