Have you looked into converting your traditional IRA to a Roth IRA? For many people, this is a good tax move. With Roth IRAs there are no required minimum distributions (RMDs) at age 70½, the money grows tax deferred, and qualified distributions are tax free. One drawback is that you must treat the taxable amount of the conversion as ordinary income for the year the conversion occurs.
- When you convert after-tax money to a Roth IRA, the amount is tax free, but you must pay taxes on the earnings of that money.
- You can’t choose to just convert after-tax money; instead, you must pool all of your IRAs and discover the proportions of after-tax and before-tax funds, then apply those percentages to the money you convert.
- Don’t pay any taxes owed from your retirement accounts because that money will be taxed as income and may incur early withdrawal penalties.
Converting to a Roth IRA Can Have Tax Consequences
You may discover that your traditional IRA has both deductible (before-tax) and nondeductible (after-tax) amounts. You might feel that you can come up with a strategy to convert those after-tax contributions first to avoid owing taxes on the amount converted. On the surface this seems like a sound plan, but, unfortunately, it is not possible. In this article we’ll show you why a plan to avoid taxes on after-tax contributions really is too good to be true.
After-Tax Contributions Reduce Conversion Tax
First of all, you might wonder how after-tax amounts even got into your traditional IRA. Well, traditional IRAs have deductibility limits. These come into effect if you and/or your spouse (if you are married) are deemed to be actively participating in an employer-sponsored retirement plan, such as a defined-contribution 401(k) or defined-benefit pension program. If this is the case, your eligibility to deduct your contribution from your income taxes is determined by your modified adjusted gross income (MAGI) and your tax-filing status.
If you are unable to deduct your contributions, the amounts will be nondeductible (after-tax) contributions. Even if you are eligible to deduct your contributions, you can choose to treat them as nondeductible contributions. After-tax money could also end up in your traditional IRA from rollovers from employer plans, such as qualified plans and 403(b) arrangements, as some of these plans allow both pretax and after-tax contributions.
When you convert after-tax money from a traditional IRA to a Roth IRA, the amount is tax-free because you have already paid taxes on those funds. The earnings, however, must be treated as ordinary taxable income.
Keep good records of all your IRA contributions because your IRA custodian is not required to do so.
An Example of Converting to a Roth IRA
For example, suppose that over the years you have contributed $10,000 to your only non–Roth IRA, and the contributions were either nondeductible or you chose not to claim deductions for the amounts. This means that you have already paid taxes on these contributions. Let’s also assume that you picked rotten investments, and the account is worth exactly what you had invested: $10,000. Now you want to convert the balance to a Roth IRA.
Guess what? The conversion will be tax free because you have already paid taxes on those funds. If the account had increased in value, you would owe income tax on only the earnings.
On the other hand, if you had deducted those contributions over the years, you would have to include the $10,000 in your income. Someone in the 22% tax bracket, for example, would have to come up with $2,200 to pay the federal taxes owed on the amount. State income taxes may also apply.
You Can’t Pick and Choose
Staying with the $10,000 example, imagine that you had paid taxes on $2,000 of the $10,000 contributions. You might think that you could covert that $2,000 and exclude the amount from your taxable income. Then the $8,000 of before-tax money could continue to grow tax-deferred in the traditional IRA. However, this can’t be done.
You may also say to yourself: “I have several IRAs. One of them has only after-tax money, while the others have deductible contributions. I’ll just convert the IRA with the after-tax amount, and then I won’t need to include the converted amount in my income.” You can certainly convert whichever account you want, but that tax strategy won’t work either.
The IRS wants its money sooner rather than later. Consequently, you can’t select which dollars—after-tax ones or before-tax ones—to convert to your Roth IRA. Instead, the $2,000 that you convert would include a prorated amount of after-tax and pre-tax amounts, in proportion to the after-tax and pretax balances in all your traditional, SEP, and SIMPLE IRAs.
Calculating the Conversion Tax for Before- and After-Tax Contributions
The IRS considers all of your non–Roth IRA assets as one pool in the calculation formula when you convert all or part of any of those IRAs to a Roth, no matter how many of these accounts you own. This includes traditional IRAs, SEP IRAs, and SIMPLE IRAs. Each dollar converted will be proportionately divided between deductible and nondeductible contributions based on the total value of all of your non–Roth IRAs.
With the above $10,000 example that had $2,000 in after-tax contributions, the $2,000 conversion would play out as follows:
- Total account value = $10,000
- After-tax contributions = $2,000
- Before-tax contributions = $8,000
- $2,000/$10,000 = 20%
- $2,000 converted x 20% = $400 converted tax free
- $1,600 subject to income tax
The same would apply to earnings in the account. Let’s say your account had increased to $15,000, and you want to convert $2,000.
- After-tax contributions = $2,000
- Before-tax contributions = $8,000
- Earnings = $5,000
- $2,000/$15,000 = 13%
- $2,000 x 13% = $260 converted tax free
- $1,740 subject to income tax
What Should You Do?
Although calculating the formula if you have multiple non–Roth accounts with deductible and nondeductible contributions can be a nuisance, the process can save you tax dollars, so keep good records of your IRA contributions. Don’t count on your IRA custodian to do it for you—it is not required to do so.
Instead, you must file IRS Form 8606 for each year you make nondeductible contributions or rollover after-tax amounts to your traditional IRA. Form 8606 must also be filed for any year that you have an after-tax balance in your non–Roth IRAs and you distribute or convert any amount from any of those IRAs. This is the only way you’ll know exactly how much of your IRA balance is after-tax amounts.
The Bottom Line
The same information will also come in handy when you begin taking RMDs or any other distributions from your traditional, SEP, or SIMPLE IRA, as only part of your distributions will be taxable. Before you convert to a Roth, calculate the tax liability. Make sure you have enough funds on hand to pay any taxes owed.
It’s better to pay the taxes from your non-retirement accounts; otherwise, you will need to include in your income for the year the amount that you withdraw to pay the taxes. This would mean that you may not only owe income taxes on the amount but also early distribution penalties if you are under age 59½ when the withdrawal occurs.
