  • Consider taking a tax deduction against your IRA contributions 

  • Withdraw Roth IRA contributions and their gains as non-taxable income during retirement

Stashing money away for your retirement is a wise, even necessary, thing to do. So as you consider saving for your future, you might want to take a look at retirement vehicles that offer tax advantages. Some accounts offer tax advantages for the year that you make your contributions; others offer tax breaks much later, when it’s time to withdraw the funds.

One of the simplest ways to benefit from tax advantages is to contribute to an Individual Retirement Account (IRA), which can provide an IRA tax deduction or tax-exempt retirement income. However, there are different kinds of IRAs to choose from, each with different benefits, rules, and limitations.

What differentiates these account types, and which one might be right for you? Let’s dive in and take a closer look.

Traditional IRA

A traditional IRA allows you to make annual contributions that you can claim as an IRA tax deduction. Instead of paying taxes on the money you contribute now, you defer those tax payments until retirement, at which you point you pay taxes on your withdrawals.

As long as your contributions don’t exceed your annual earned income, the amount you can contribute to your traditional IRA is as follows:

  • If you’re under the age of 50, you can contribute as much as $5,500 for 2018 and $6,000 in 2019
  • If you’re 50 or older, you can benefit from the $1,000 IRA “catch-up” rule, which allows you to contribute as much as $6,500 for 2018 and $7,000 for 2019

You can contribute to a traditional account for an IRA tax deduction up until the filing deadline, which this year is April 15, 2019, for the 2018 tax year. Traditional IRA tax deductions can lower your tax bill for your filing year, with your total contribution being fully deductible if neither you nor your spouse is covered by a workplace retirement plan.

If you are covered by a workplace retirement plan, then your contribution may be fully or partially deductible depending on your modified adjusted gross income, which is your gross income minus any deductions. Once your modified adjusted gross income exceeds a certain amount, the amount of deductions you can take for IRA contributions begins to reduce. Here’s how the phase-out works:

  • If you’re a single filer, your phase-out range for tax year 2018 was $63,000 to $73,000; for 2019, it’s $64,000 to $74,000.
  • If you’re a joint filer, your phase-out range for 2018 was $101,000 to $121,000; for 2019, it’s $103,000 to $123,000.

Each type of IRA has different benefits, rules, and limitations. Which one might be right for you?

It’s important to be aware of required minimum distributions, or RMDs, from traditional IRAs. There are steep penalties that you will incur if you fail to make the required withdrawals from your traditional IRA—as high as 50% of the amount you should have withdrawn. These RMDs do not have to begin until you turn 70 1/2. In addition, if you withdraw funds from a traditional IRA before the age of 59 1/2, you’ll be subject to a 10% early withdrawal penalty. Plus, your funds will be taxed as regular income.

If you happen to be a small business owner or self-employed, you can use a SIMPLE IRA plan or Simplified Employee Pension (SEP) to save up for retirement. There are also plenty of other retirement plans available for self-employed entrepreneurs.

Roth IRA

A Roth IRA account has many features that are similar to a traditional IRA account, but its tax advantages are different. Essentially, contributions to a Roth IRA account are not tax deductible when you file taxes for the year. Instead, the contributions provide tax-free income on all your withdrawals and earnings once you’re in retirement.

So, when choosing between a traditional or a Roth IRA, it’s a matter of deciding whether you think it’s best to pay taxes now, at your current tax rate, or later when you’re retired. Keep in mind that under the current law, your taxable income during retirement can affect a number of expenses, such as your Medicare premium. So a Roth IRA, by providing non-taxable income, has the advantage of not increasing expenses like your Medicare premium, whereas distributions from your traditional IRA might.

Also, a Roth IRA does not carry a required minimum distribution for withdrawal, as a traditional IRA does. However, like a traditional IRA, you will incur a 10% penalty for early withdrawal, or before age 59 1/2.

Your contribution limits for a Roth IRA tax deduction are the same as those for a traditional IRA. But the amount you can contribute will begin to phase out once you reach a certain income. Here are the phase-out limits:

  • For single filers, contributions for tax year 2018 begin phasing out at $120,000, and are ineligible at $135,00; for tax year 2019, phase-out begins at $122,000, ineligible at $137,000.
  • For joint filers, contributions for 2018 begin phasing out at $189,000, ineligible at $199,000; for tax year 2019, phase-out begins at $193,000, ineligible at $203,000.

If you’ve made the transition from being employed to self-employed, or if you’ve experienced a significant drop in income, and hence a drop in tax rate, you might want to consider how converting to a Roth IRA would benefit you, because you would likely pay lower taxes up front.

Keep in mind that under the new tax laws, you may no longer reverse a rollover into a Roth IRA. So if you made a conversion or rollover into a Roth IRA after January 1, 2018, you’re stuck with it. 

Note that there are a few more rules that apply to the phasing out of both your contribution and deductibility. To learn more, you can visit the page on 2018 deduction limits, the page for 2019, the TD Ameritrade page on IRA and Roth IRA rules, or contact a tax consultant.
