Roth retirement accounts are often described in simple terms: pay tax now, allow the assets to grow, and take qualified withdrawals without federal income tax later. That basic framework still applies, but recent changes have added new choices and new tax consequences to workplace retirement accounts, such as 401(k), 403(b), and 457(b). In 2026, higher contribution limits, mandatory Roth treatment for some catch-up contributions, and optional Roth employer matches can affect both retirement savings and the current-year tax return.
Employees and business owners should review these rules before changing payroll elections or assuming that every amount deposited into a Roth account has already been covered through paycheck withholding.
Roth employer contributions may create taxable income
Under SECURE 2.0, an employer-sponsored plan may allow employees to designate certain matching or nonelective contributions as Roth contributions. Previously, employer contributions generally went into a pre-tax account, even when the employee made personal deferrals to a Roth 401(k). The employee did not include the employer contribution in current taxable income. Tax was deferred until the money was withdrawn.
When an employee elects Roth treatment for an eligible employer contribution, the contribution is included in the employee’s gross income for the year it is allocated. The amount is generally reported on Form 1099-R, rather than as regular wages on Form W-2. This income will be treated as ordinary taxable income but is not subject to payroll taxes according to IRS Notice 2024-2.
The tax can surprise employees because the contribution does not create additional cash in their paycheck and is generally not subject to federal income tax withholding. An employee may therefore receive a retirement plan contribution and a corresponding tax bill without having set aside cash to pay it.
Before electing a Roth employer match, participants should estimate the added federal and state income tax and consider whether they need to adjust payroll withholding or make estimated tax payments.
The plan must also permit Roth employer contributions, and the contribution must be fully vested when allocated. Employees should review the plan document and election materials rather than assuming the feature is available.
Higher-paid employees face a new Roth catch-up rule
Beginning in 2026, certain employees who make age-based catch-up contributions must make those contributions on a Roth basis.
The rule generally applies when an employee:
- Is eligible to make catch-up contributions (at age 50)
- Participates in a plan that offers a Roth feature
- Received more than $150,000 of prior-year FICA wages from the employer sponsoring the plan
For 2026 contributions, the wage test generally looks to 2025 wages from that employer. The threshold applies to wages, not total adjusted gross income, household income, or income from every source. Additionally, since it applies to wages from the specific employer, if they changed jobs, the requirement may or may not apply.
An owner receiving pass-through income from an S corporation may have substantial total income but remain below the threshold if the owner’s FICA wages do not exceed the applicable amount. Conversely, an executive with wages above the threshold may be required to use Roth treatment even when a current-year deduction would better fit the individual’s tax plan.
Plans, payroll providers, and employers should confirm that their systems can identify affected participants and process the contributions correctly.
Contribution limits increased for 2026
The basic employee contribution limit for most 401(k), 403(b), and governmental 457 plans increased to $24,500 for 2026.
The general catch-up contribution limit for participants age 50 or older increased to $8,000. Participants who are ages 60 through 63 at the end of 2026 may qualify for the higher $11,250 catch-up limit.
The combined limit for traditional and Roth IRA contributions increased to $7,500. Taxpayers age 50 or older may contribute an additional $1,100, bringing the total to $8,600.
Direct Roth IRA contributions remain subject to income limitations. For 2026, the phaseout range is $153,000 to $168,000 for single filers and heads of household and $242,000 to $252,000 for married couples filing jointly.
Higher-income taxpayers who cannot contribute directly may consider a backdoor or Mega Backdoor Roth strategy, but those strategies require careful review of existing IRA balances, plan terms, conversion timing, and tax reporting.
A Roth election should fit the broader tax plan
Roth treatment is not automatically better than pre-tax treatment. The choice depends on the taxpayer’s current marginal rate, expected retirement income, available cash, state residency, investment horizon, and estate plan.
A Roth contribution may be attractive when the taxpayer expects higher future tax rates or values tax-free retirement distributions. A traditional contribution may be more useful when the current deduction reduces income taxed at a comparatively high rate.
Taxpayers should also account for Roth conversions, business income, capital gains, equity compensation, charitable giving, Medicare premium thresholds, and other transactions planned for the same year.
Roth IRAs and designated Roth 401(k) accounts are not subject to required minimum distributions during the original owner’s lifetime. Beneficiaries, however, remain subject to inherited-account distribution rules.
How Aura Advisors can help with Roth retirement planning
The expanded Roth rules give taxpayers more control over when retirement savings are taxed, but each election affects current cash flow and future flexibility.
Before choosing Roth treatment for employer contributions, employees should calculate the resulting taxable income and confirm how the tax will be paid. Business owners should coordinate plan design, payroll administration, participant communications, and tax reporting. Higher-paid employees approaching age 50 should determine whether the mandatory Roth catch-up rule applies before year-end contribution elections are finalized.
Aura Advisors can model Roth and traditional contribution options, evaluate withholding and estimated tax needs, review conversion opportunities, and coordinate retirement decisions with the taxpayer’s business, investment, and estate planning facts.
