Taxes are a valid concern if you want to withdraw more than $720,000 from your retirement fund to a Roth IRA. While you won’t pay any taxes if the assets you roll over are held in another Roth account, there’s generally no way to completely avoid paying taxes when you contribute pre-tax money to a Roth IRA. However, with a few strategic steps, you can limit today’s tax pains while still reaping future tax-free benefits. To determine whether a Roth rollover fits your overall tax-saving strategy, consider running the numbers with a financial advisor that matches your financial situation and retirement vision.

A Roth IRA is a retirement account that allows people to contribute after-tax dollars. Unlike a traditional IRA, you don’t get a tax break on Roth funds. However, qualified Roth withdrawals in retirement can be made tax-free. This differs from traditional IRAs, whose contributions are often tax-deductible but withdrawals are taxed as ordinary income.

In general, you can withdraw funds from another retirement account such as a traditional IRA or 401(k) to a Roth IRA. This is called a Roth conversion or a Roth rollover. If you convert funds, you owe income tax on the amount rolled over that year. So if you roll over $50,000 from a traditional IRA to a Roth IRA, $50,000 is added to your taxable income for the year.

It is important to understand that Roth rollovers are not the same as Roth contributions. High-income taxpayers may not be eligible to make direct Roth contributions. However, there are no income limits for making Roth conversions from other accounts.

You can withdraw funds from 401(k)s, 403(b)s, 457 plans, traditional IRAs, SEP IRAs and simple IRAs. To start the process, contact the institution that manages the account you want to open and convert. They can help transfer. You generally have 60 days to complete the conversion, otherwise, the IRS will treat the transfer as a distribution and you may incur a 10% early withdrawal penalty. But if you need more help deciding how much to convert and convert, consider talking to a financial advisor.

Rolling assets into a Roth IRA will generate tax but will also allow for tax-free growth and withdrawals.

There are several important reasons why one might choose to do a Roth conversion:

Tax-free growth: Money converted to a Roth IRA grows tax-free. This differs from traditional IRAs whose investment earnings are tax-deferred but are ultimately taxable upon withdrawal. Roth withdrawals are 100% tax-free, as long as you meet the five-year rule and are 59.5 years old.
Avoid RMDs: Traditional IRAs are subject to required minimum distributions (RMDs) – mandatory withdrawals that begin at age 73. For those who do not need these distributions, RMDs can create excess taxable income. However, a Roth conversion eliminates future RMDs since Roth accounts are not subject to these rules.
Tax savings: Paying conversion taxes now can make sense if you expect to be in a higher tax bracket when you retire. Roth conversions lock in today’s rates. They also lower future RMD amounts that can push you into a higher bracket.
Estate planning: Heirs who receive Roth IRAs may be able to extend tax-free distributions during their lifetime, depending on their relationship to the deceased. However, some beneficiaries will have to withdraw the account within 10 years.

As you can see, there are good reasons to convert an IRA or 401(k) to a Roth IRA, but a financial advisor can help you evaluate how such a transaction could affect your finances and your tax liability.

When you do a Roth conversion, the main drawback is the tax liability. There are strategic steps to reduce taxes, though:

Partial conversion: One way is to do a partial Roth conversion over several years instead of converting your entire balance at once. The idea is to convert enough each year to “fill” your current income bracket while avoiding a higher bracket.
Low tax years: In the low-income age it may make sense to convert larger sums. This may be early retirement before RMDs or Social Security begin. Also, the goal is to add enough extra income to fill your current tax bracket without pushing you into the next tax bracket.
Use non-retirement assets: Many experts suggest paying conversion taxes with non-retirement funds instead of IRA assets. This allows your entire IRA balance to transfer to a Roth account and continue to grow tax-free.

One calculates how much they could end up paying in taxes on a Roth IRA rollover.

As an example, let’s consider a single taxpayer who wants to roll over $720,000 from an old 401(k) to a Roth IRA. Here are a few scenarios to consider:

Converting the entire $720,000 would generate nearly $220,000 in taxable income at today’s top marginal rate of 37% (assuming you take the standard deduction of $14,600). That amount must be paid in the year in which the conversion is completed.

Completing a series of conversions each year for 10 years controls overstepping the tax bracket and spreads the tax involved over ten years. A $72,000 annual conversion would put you in the 22% bracket if you have little or no extra cash. That means a tax bill of about $7,700 a year or $77,000 over 10 years — less than half of what you’d pay in a lump sum conversion. Keep in mind that your balance may continue to grow during these 10 years, requiring more changes and more taxes to pay.

By increasing the conversion over the years in which your income comes in, you can take advantage of being in a lower tax bracket. For example, let’s say you earn $60,000 in taxable income in a typical year, which puts you in the 22% bracket and results in a tax liability of about $5,200 after taking the standard deduction. If you also convert $72,000, you’ll move up to the 24% bracket for $132,000 of gross taxable income. You’ll see your tax bill rise to about $21,000. Do this for two years in a row and your combined tax bill will be around $42,000.

But he says he’ll only get $30,000 in one year because he’s taking a six-month sabbatical. You can skip the conversion in the previous year and convert two years’ worth, or $144,000, into the sabbatical year. That year, you will have $174,000 in income, including $144,000 in turnover and $30,000 in salary. This will put you in the 24% bracket and generate an estimated $31,000 in income tax. Add the $5,200 tax bill from last year and your two-year tax bill would total $36,200. A financial advisor can help you assess whether this strategy may be an option for you.

Using non-IRA funds to pay your taxes on the rollover allows the full amount of the rollover to go into the Roth account. If you use taxable funds rather than IRA funds to pay all taxes due on the $720,000 total, that’s $227,000 more tax-free growth in your Roth.

Roth rollovers can reduce future taxes and eliminate RMDs in retirement, at the cost of paying more taxes today. Strategic partial conversions completed within a few years, timed conversions for low income years can limit tax pain, and using non-retirement assets to pay conversion taxes. Consult with financial and tax professionals for guidance on tax understanding.

With a big retirement move like a Roth conversion, it helps to stay with a financial advisor who can analyze your full financial picture. Finding a financial advisor doesn’t have to be difficult.

Keep an emergency fund on hand in case you run into an unexpected expense. An emergency fund should be liquid — in an account that isn’t exposed to significant fluctuations like the stock market. The tradeoff is that the value of cash can erode due to inflation. But a high interest account allows you to earn compound interest. Compare savings accounts from these banks.
