Are Roth Conversions Right for You? Benefits, Costs, and When They Make Sense
Roth conversions can be a powerful retirement and tax planning tool. A Roth conversion involves moving money from a Traditional IRA or 401(k) into a Roth IRA. But it comes with significant trade-offs. You need to evaluate how a Roth conversion will impact your taxes, retirement income, and overall financial situation today and in the future.
Benefits of a Roth Conversion
Tax-Free Growth and Withdrawals
As with other retirement accounts, Roth IRAs grow tax-free. And withdrawals from Roth IRAs are after-tax, including all investment gains.
No Required Minimum Distributions (RMDs)
Original Roth IRA owners do not face Required Minimum Distributions (RMDs) as you do with Traditional IRAs. You can withdraw monies as needed.
Tax Rate Arbitrage
Retirement plan distributions are taxable; they can make more of your Social Security taxable and cause higher Medicare premiums. Roth distributions avoid those issues.
Estate Planning Benefits
Roth IRAs pass tax-free to your beneficiaries. (They are still subject to the 10-year rule.) This is especially beneficial if your heirs are in higher tax brackets. They may avoid a tax bomb.
No Income Limits
Direct Roth IRA contributions are subject to income limits. Roth conversions are not. This makes them accessible even to high earners.
Portfolio Tax Diversification
Having both pre-tax and after-tax retirement accounts provides flexibility to manage taxable income year-to-year in retirement.
Costs of a Roth Conversion
Immediate Tax Bill
The converted amount is taxed as ordinary income in the year of conversion. This can create a large, upfront tax liability. Or you can spread the conversion amounts over several years and spread out the tax liability.
Potential Bracket Creep
Converting too much in one year can push you into a higher federal tax bracket. Careful tax planning is needed to avoid increasing your effective tax rate.
Medicare and Social Security Impacts
Higher adjusted gross income (AGI) from conversions can trigger IRMAA surcharges on Medicare premiums. The additional conversion income can increase the amount of Social Security benefits that are taxable.
Liquidity Requirement
To maximize the benefit, you should pay the conversion tax from non-retirement funds. Using retirement assets (401(k), IRA) to pay the taxes reduces the amount working for you. It may also cause a 10% penalty if you are under 59-1/2.
Five-Year Rule Complications
Each conversion starts its own five-year clock. Withdrawals of converted principal before age 59-1/2 and before five years may incur a 10% early withdrawal penalty.
When Do Roth Conversions Make Sense?
Based on these benefits and costs, when do Roth conversions make sense?
- You are in a temporary low-income window (i.e., early retirement before RMDs and Social Security).
- You expect significantly higher future tax rates.
- You want to reduce future RMDs and legacy taxes for your heirs.
- You have sufficient liquid assets outside retirement accounts to pay the conversion tax.
When Should You Be Cautious About Roth Conversions?
When is it time to be cautious or avoid Roth conversions?
- When you are in your peak earning years and already in a high tax bracket.
- You will need the converted retirement funds soon. You don’t get the full benefit of tax-deferred growth.
- You lack the cash to pay the tax bill.
- The conversion would push you over IRMAA or other income thresholds with significant costs.
- You are charitably inclined. With a Traditional IRA, you can make a Qualified Charitable Distribution (QCD) at 70-1/2 without increasing your income.
Is a Roth Conversion Right for You?
Roth conversion benefits may outweigh the costs or disadvantages. Yet there are many moving parts: you can impact your taxable Social Security benefits, your Medicare premiums, and your overall taxes.
Determining whether a Roth conversion makes sense requires looking at your current tax bracket, future retirement income, Required Minimum Distributions, Medicare premiums, Social Security benefits, and long-term financial goals. This is a place to seek the advice of a tax-aware financial planner.
