Individual Retirement Account
Contributing to a traditional Individual Retirement Account (IRA) is a win-win move that lets you boost your retirement savings and trim your tax bill at the same time. The contribution limit is $5,500 ($6,500 if you’re 50 or older) for 2018, and if you don’t have a retirement plan at work (or your spouse does), every dollar of that can be knocked off your income.
If you’re covered by a retirement plan at the office (or your spouse is) then that deduction might be limited by your income. You may make 2018 IRA contributions up until April 15, 2019.
