What is Individual Retirement Account (IRA)?
An IRA is a personal retirement account you open yourself, independent of any employer.
How it works
A traditional IRA may give you a deduction now, with tax due at withdrawal. A Roth IRA is funded with after-tax dollars but grows and pays out tax-free. Contribution limits are lower than a 401(k)'s, and deductibility can phase out if you're also covered by a workplace plan.
A quick example
What people get wrong
You can contribute to last year's IRA right up to the April tax deadline. That gives you a rare chance to lower your tax bill after the year has already ended.
