Eight Ways to Get Money Into a Roth IRA (And the Traps in Each One)

If you earn too much to contribute directly to a Roth IRA, you may assume the door is closed. It is not. In practice, there are several ways to move money into Roth accounts, and each route has different eligibility rules, limits, tax consequences, and timing requirements.

Why does this matter? Roth money can grow tax-free, and qualified withdrawals are generally tax-free. The original owner of a Roth IRA also does not have to take lifetime required minimum distributions. For business owners and high-net-worth families, that flexibility can become an important part of retirement, succession, and tax planning.

The key is choosing the right door rather than treating every Roth strategy as interchangeable.

1. Can You Make a Direct Annual Roth IRA Contribution?

If you have taxable compensation and your income falls within the applicable limits, a direct contribution is the simplest route.

For 2026, you can contribute up to $7,500 to all of your traditional and Roth IRAs combined, or $8,600 if you are age 50 or older. Your contribution cannot exceed your taxable compensation for the year. The IRS adjusts these limits periodically for inflation. See the IRS’s 2026 IRA limits.

Your modified adjusted gross income, or MAGI, also matters. For 2026, direct Roth IRA contributions phase out between:

• $153,000 and $168,000 for single or head-of-household filers
• $242,000 and $252,000 for married couples filing jointly
• $0 and $10,000 for married filing separately if you lived with your spouse during the year

The trap is assuming your salary tells the entire story. A large bonus, business distribution, investment gain, or sale of company interests can push your MAGI into the phase-out range, or above it.

2. Is a Backdoor Roth IRA Appropriate?

A backdoor Roth is a two-step strategy:

1. Make a nondeductible contribution to a traditional IRA.
2. Convert that contribution to a Roth IRA.

A conversion is simply a movement of money from a traditional retirement account into a Roth account. The conversion may create taxable income, although a properly executed contribution-and-conversion sequence can often limit the taxable amount.

The major trap is the pro-rata rule. The IRS looks at all of your traditional, SEP, and SIMPLE IRAs together when determining how much of a conversion is taxable. It does not allow you to isolate only the account containing your new nondeductible contribution.

For example, suppose you contribute $7,500 after tax and have $92,500 in other pre-tax IRA assets. If you convert $7,500, only a portion may be treated as tax-free basis. The rest can be taxable.

One potential fix is rolling eligible pre-tax IRA funds into a current employer’s 401(k), assuming the plan accepts rollovers. That may remove those assets from the pro-rata calculation because the rule generally focuses on traditional, SEP, and SIMPLE IRA balances, not qualified employer plans. Coordinate the timing carefully, particularly around December 31.

You will also generally need to report the nondeductible contribution and conversion on Form 8606. The IRS explains the basis and reporting rules in Publication 590-A.

3. Could Your Business Open the Mega Backdoor Roth Door?

For many business owners and highly compensated employees, the mega backdoor Roth is the largest potential funding route.

It generally involves:

• Making after-tax employee contributions to a 401(k) beyond the normal elective deferral limit
• Moving those contributions into Roth status through either an in-plan Roth conversion or an in-service rollover to a Roth IRA

After-tax contributions are money contributed after income tax has already been paid. They are different from designated Roth 401(k) contributions, which count toward the regular employee deferral limit.

The strategy depends entirely on plan design. Your 401(k) must permit after-tax contributions and also allow an in-plan conversion or in-service distribution. The plan may need careful testing and administration as well.

For 2026, the regular 401(k) elective deferral limit is $24,500, separate from the plan’s broader annual additions limit. The total amount that can enter a plan may include employee deferrals, employer contributions, and after-tax contributions.

That is why this strategy is particularly relevant to business owners: the business owner may literally control whether this door is open. A plan designed only around basic salary deferrals may leave substantial Roth capacity unused.

4. Should You Use a Roth 401(k) at Work?

A Roth 401(k) is an employer plan account funded with designated Roth contributions. You pay income tax on the contribution today, but qualified future distributions can be tax-free.

Your traditional and Roth 401(k) deferrals share the same annual employee limit. You cannot contribute $24,500 to a traditional 401(k) and another $24,500 to a Roth 401(k) in 2026.

Under current rules, some employer contributions, including matching or nonelective contributions, may be designated as Roth if the plan allows it. Choosing that option generally makes the contribution taxable income to you in the year it is made. That can be attractive in a lower-income year, but expensive when income is already high.

Designated Roth accounts no longer have the old lifetime RMD requirement beginning in 2024. Still, at separation from service, rolling the Roth 401(k) into a Roth IRA may provide more flexibility, broader investment choices, and simpler long-term administration.

The plan document controls what is actually available. Section 402A of the Internal Revenue Code outlines the statutory framework for designated Roth accounts.

5. Is a Roth Conversion Better Than Waiting?

A Roth conversion moves pre-tax money from a traditional IRA or eligible pre-tax 401(k) balance into a Roth IRA. The converted amount is generally included in taxable income for the year of conversion.

Why voluntarily pay tax now? You may be buying decades of future tax-free growth and reducing the amount of money subject to future income tax and RMDs.

The most effective approach is usually not a single dramatic conversion. It is a multi-year tax-bracket filling strategy. You convert enough each year to use a targeted tax bracket without unnecessarily pushing income into a higher bracket.

Business owners should pay close attention to the years before and after a sale:

• Before a sale, income may be elevated by business profits, bonuses, or a transaction.
• During a transition year, income may temporarily fall.
• After a sale, employment income may decline even as investment income changes.

A conversion that makes sense during a lower-income transition year may be unnecessarily costly during the sale year. Remember that the conversion itself is a taxable event, so estimate federal and state taxes before executing it.

6. Can a Non-Working Spouse Fund a Roth IRA?

A spouse does not necessarily need their own paycheck to make a Roth IRA contribution.

If you are married filing jointly, the working spouse’s taxable compensation may support contributions for both spouses, subject to the combined compensation and IRA limits. Each spouse has a separate IRA and a separate annual contribution limit.

For example, if one spouse earns $30,000 and the couple has no other compensation, the household generally cannot contribute more than $30,000 across both IRAs. But if the couple has $100,000 of eligible compensation, each spouse may potentially contribute up to their individual limit, assuming the income rules are satisfied.

This can be especially useful when one spouse is focused on raising children, managing the household, or assisting with a family business without receiving formal compensation.

7. What Roth Options Are Available to the Self-Employed?

If you own a business, your retirement plan may offer more flexibility than a standard workplace plan.

A solo 401(k) can allow Roth employee deferrals, provided the plan document includes that feature. You may contribute as both employee and employer, subject to the applicable limits and business income calculations.

A SIMPLE IRA can also offer a Roth option under current rules, although implementation depends on the plan and provider. Roth SIMPLE contributions are made with after-tax dollars and follow SIMPLE plan limits rather than the regular Roth IRA limit.

The important asymmetry is that SEP-IRAs cannot be Roth accounts. A SEP can be attractive for making employer contributions, but it does not provide a Roth employee-deferral feature. If Roth contributions are a priority, a solo 401(k) may offer more flexibility.

Business owners should evaluate the entire plan design, not just the contribution limit. Employee coverage, nondiscrimination testing, administrative costs, and the ability to add after-tax contributions can materially change the outcome.

8. Can Unused 529 Money Move Into a Roth IRA?

SECURE 2.0 created a limited way to move unused 529 funds into a Roth IRA for the 529 beneficiary.

The main requirements include:

• The 529 account must generally have been open for at least 15 years
• The beneficiary must have earned income
• Contributions and related earnings made within the previous five years generally cannot be rolled over
• The lifetime rollover limit is $35,000 per beneficiary
• The annual amount is limited by the Roth IRA contribution cap, reduced by other IRA contributions made that year

For example, if a beneficiary under age 50 makes a $3,000 Roth IRA contribution in 2026, the maximum possible 529-to-Roth rollover for that year would generally be $4,500, assuming all other requirements are met.

This can be useful for a business owner who overfunded a child’s 529 account and does not want the money trapped in an education-only structure. The rollover must go to the beneficiary’s Roth IRA, not the parent’s Roth IRA.

The IRS’s retirement guidance and Fidelity’s SECURE 2.0 overview provide additional background.

What Mistakes Can Disrupt the Strategy?

Could a well-intended Roth plan create taxes or penalties? Yes. Watch for these recurring mistakes:

• Exceeding the annual contribution cap: The $7,500 or $8,600 limit applies across all of your traditional and Roth IRAs, not separately to each account. Excess contributions can trigger a 6% excise tax while they remain uncorrected.
• Ignoring the pro-rata rule: A backdoor Roth conversion considers all traditional, SEP, and SIMPLE IRA balances.
• Failing to track the five-year clocks: The conversion five-year rule can affect whether a converted amount is subject to the 10% early-distribution tax. Separately, the Roth IRA account five-year rule affects when earnings can be withdrawn tax-free.
• Assuming a backdoor conversion is always tax-free: Pre-tax dollars and investment earnings converted to Roth status can create taxable income.
• Converting during an inflated-income year: A business sale, large bonus, or unusually profitable year can make a conversion far more expensive than expected.

Which Roth Route Fits Your Situation?

• You have moderate income and earned compensation: Start with a direct Roth IRA contribution.
• You exceed the direct Roth income limits but have no significant pre-tax IRA balances: Consider a backdoor Roth.
• You own a business or have a highly flexible 401(k): Review mega backdoor Roth provisions and after-tax contribution capacity.
• Your employer offers a Roth 401(k): Compare current tax rates with your expected future tax environment.
• You have substantial pre-tax retirement assets: Model a multi-year Roth conversion strategy.
• Your spouse does not work outside the home: Review spousal Roth IRA eligibility.
• You are self-employed: Compare a solo 401(k), SIMPLE IRA, and SEP structure before choosing a plan.
• You have overfunded a long-standing 529: Check whether a beneficiary Roth rollover is available.

The number of available doors is itself a reason not to treat these as isolated tax tricks. The right answer depends on your income, business structure, existing retirement accounts, plan documents, tax bracket, liquidity, and long-term estate goals.
