When you are thinking about how to put your hard-earned dollars to work, it’s important to consider every avenue for tax-advantaged savings. Backdoor Roth IRA contributions are great tools for high earners to take advantage of Roth IRAs even after passing the income limits for standard contributions, and the steps for making backdoor Roth IRA contributions are pretty simple. However, the documentation and tax forms for the process can be confusing, and you may run into trouble when it comes time to report everything to Uncle Sam. Whether you work with a professional tax preparer, use tax software such as TurboTax or complete your taxes by hand, understanding the mechanics of the money movements can help ensure you file your taxes correctly.
Let’s walk through each step in the backdoor Roth IRA process to illustrate the moving parts. You got here by making too much money to deduct Traditional IRA contributions or to contribute to a Roth IRA normally. However, there is no income limit on converting a Traditional IRA to a Roth IRA, which is the crux of the backdoor Roth IRA.
Step one of the Backdoor Roth IRA is making a non-deductible contribution to your Traditional IRA. It’s your responsibility to report the non-deductible contribution to your Traditional IRA at tax time on IRS form 8606, Nondeductible IRAs. Form 8606 helps track your basis and avoid paying additional tax on your non-deductible contribution as you convert the balance to a Roth IRA.
The second step after making your non-deductible Traditional IRA contribution is converting your Traditional IRA balance to a Roth IRA. You will owe tax on any earnings in the Traditional IRA before converting, but from that point on, those dollars are now Roth IRA assets and aren’t subject to future tax. Use Form 8606 for calculating the taxable amount from the conversion if you had any earnings in the Traditional IRA.
Around tax-time, you’ll receive a 1099-R from your custodian showing the distribution from your Traditional IRA that was converted to your Roth IRA the previous year. Later in the year you’ll also receive an information reporting Form 5498 that shows the contribution you made to the Traditional IRA and the amount that was converted to Roth. We recommend keeping Form 5498 for your records, but you don’t need to report Form 5498 in your tax filing.
Now that we have walked through the steps, let’s look at an example of how to report a backdoor Roth IRA contribution. Tom, a 35-year-old physician in the Pacific Northwest and diehard Seahawks fan, is working on his Married Filing Jointly tax return after making a $6,000 non-deductible Traditional IRA contribution last year that he converted to his Roth IRA. Tom didn’t have any other Traditional IRA assets aside from his non-deductible contribution in 2018, and he didn’t have any earnings in his Roth IRA conversion. Part 1 of Tom’s Form 8606 is filled out below.
Next let’s look at Part 2 of Tom’s Form 8606, where the conversion portion is reported. If line 18 is 0, as it is in this example, none of the conversion ends up being taxable.
Note: Our example uses the increased 2019 IRA contribution limit ($6,000 for individuals under age 50) on the 2018 tax year forms. The 2019 tax year forms won’t become available until January 2020.
Tom won’t end up owing any taxes on his Backdoor Roth IRA, and his correct reporting of the contribution and conversion will avoid running afoul of the IRS. However, tax forms and reporting can be a daunting challenge. If stressors like tax law changes, new forms and confusion around the whole process keep you from sleeping soundly, reach out to a Merriman advisor to discuss whether a backdoor Roth IRA makes sense for you. You might even have other options available for tax-advantaged savings that you haven’t considered.
