Yes, there’s still time to make 2016 contributions to your IRA. The deadline for such contributions is April 18, 2017. If the contribution is deductible, it will lower your 2016 tax bill. But even if it isn’t, making a 2016 contribution is likely a good idea.
Tax-advantaged retirement plans allow your money to grow tax-deferred — or, in the case of Roth accounts, tax-free. But annual contributions are limited by tax law, and any unused limit can’t be carried forward to make larger contributions in future years. So it’s a good idea to use up as much of your annual limits as possible. Have you maxed out your 2015 limits?
