Retirement Account Options and Tax Rules to Know for 2026

Choosing the Right Retirement Account for Your Situation

Key Takeaways

• Compare tax rates now and later. Pretax accounts may be appealing when current tax rates are high; Roth accounts may be attractive when future tax rates are expected to be higher.
• Coordinate IRA and employer plan limits. IRA contribution limits are separate from employer plan deferral limits, but deductibility and Roth IRA eligibility may depend on income and employer plan participation.
• Do not overlook catch-up contributions. Clients age 50 and older, and especially those age 60 to 63, may have additional savings opportunities in employer plans.
• Match the plan to the business. A SEP IRA may offer simplicity and flexibility, while a SIMPLE IRA may work well for smaller employers that want employee salary deferrals with required employer contributions.

Retirement Account Options and Federal Tax Considerations for 2026

Retirement accounts can be powerful tax-planning tools, but the “best” account often depends on a client’s income, access to an employer plan, age, cash flow, business structure, and retirement goals. Below is a practical overview of several common IRA and employer-sponsored retirement arrangements and the federal tax rules clients should keep in mind.

General information only: This article is intended as a high-level summary. Contribution eligibility, deductibility, distribution planning, and rollover decisions are fact-specific. Please consult your CPA or tax advisor before making retirement account decisions.

1. Traditional IRAs

A traditional IRA allows eligible individuals to save for retirement on a tax-deferred basis. Contributions may be deductible, earnings generally grow tax-deferred, and distributions are generally taxable when withdrawn.

2026 contribution limits

For 2026, total annual contributions to all traditional and Roth IRAs combined are limited to the lesser of compensation or $7,500, plus a $1,100 catch-up contribution for individuals age 50 or older, for a total of $8,600. For IRA purposes, compensation generally includes earned income such as wages, salaries, professional fees, and other amounts received for performing services under IRC § 219(f)(1).

Deductibility and income phaseouts

Whether a traditional IRA contribution is deductible under IRC § 219 depends in part on whether the taxpayer or spouse is an active participant in an employer-sponsored retirement plan. For 2026, the deduction phaseout ranges for active participants are:

If only one spouse is an active participant in an employer plan, the nonparticipant spouse’s deduction phases out at $242,000–$252,000 of combined AGI for 2026; if neither spouse is a participant, the deduction is not phased out. Modified AGI for this purpose generally adds back items such as the IRA deduction, certain savings bond interest exclusions, foreign earned income and housing exclusions, adoption benefits, and student loan interest deductions under IRC § 219(g)(3).

Tax treatment

Traditional IRA distributions are generally taxable to the extent they represent deductible contributions and earnings. Nondeductible contributions, if properly tracked on Form 8606, create basis that is not taxed again when distributed.

2. Roth IRAs

A Roth IRA is funded with after-tax dollars. Contributions are not deductible, but qualified distributions can be entirely federal income tax-free.

2026 contribution limits and income phaseouts

Roth IRA contributions are governed by IRC § 408A. For 2026, the IRA contribution limit is generally $7,500, or $8,600 for individuals age 50 or older, reduced by any traditional IRA contributions for the year. Roth IRA contributions are not deductible under IRC § 408A(c)(1).

For 2026, Roth IRA eligibility phases out over the following modified AGI ranges:

Participation in an employer-sponsored retirement plan does not, by itself, prevent a Roth IRA contribution; eligibility is based on modified AGI and other Roth IRA rules.

Qualified and nonqualified distributions

A Roth IRA qualified distribution is generally tax-free and penalty-free if it is made after the five-tax-year period beginning with the first tax year for which a Roth IRA contribution was made and is made after age 59½, due to death, due to disability, or for qualified first-time homebuyer expenses up to the lifetime limit under IRC § 408A(d)(2).

If a Roth IRA distribution is not qualified, the distribution is taxable only to the extent attributable to earnings. Roth IRA ordering rules generally treat distributions first as a return of regular contributions, then conversions, and finally earnings under IRC § 408A(d)(4).

3. 401(k) Plans

A 401(k) plan is an employer-sponsored retirement plan commonly used by businesses of many sizes. Employees may defer part of their compensation into the plan, and employers may provide matching or nonelective contributions.

2026 limits

For 2026, the elective deferral limit under IRC § 402(g) is $24,500 for 401(k), 403(b), and 457 plans, as well as SARSEPs. The 2026 annual additions limit under IRC § 415(c) increases to $72,000, and the compensation limit under IRC § 401(a)(17) increases to $360,000.

Catch-up contributions under IRC § 414(v) for 401(k), 403(b), 457 plans, and SARSEPs are $8,000 in 2026 for participants age 50 or older who do not attain ages 60–63 during the year. For participants who attain ages 60, 61, 62, or 63 during the year, the catch-up limit remains $11,250.

Tax treatment

Traditional 401(k) elective deferrals generally reduce current taxable income, while distributions are generally taxable when paid out. Employer contributions to qualified retirement plans are generally excluded from the employee’s gross income and are not treated as wages for federal income tax, FICA, or FUTA purposes. Qualified plan distributions are taxable to the extent attributable to employer contributions, pretax employee deferrals, and earnings.

4. SEP IRAs

A SEP IRA can be attractive for self-employed individuals and small business owners because it is relatively simple to administer and is funded by employer contributions.

For 2026, SEP contributions are generally limited to the lesser of 25% of compensation or $72,000. SEP contributions are also considered in applying the IRC § 415 defined contribution plan annual additions limit. Employer deductible contributions to SEPs are generally subject to the same limits as profit-sharing, money purchase, and stock bonus plans, generally the lesser of 25% of compensation or $72,000 for 2026.

Because SEP contributions are employer contributions, they can be useful for business owners with variable income who want flexibility in whether and how much to contribute each year.

However, unlike a 401(k) or other “qualified plan,” a SEP is not an IRC § 401(a) qualified plan. Instead, IRC § 408(k)(1) defines a SEP as an individual retirement account or individual retirement annuity.

This IRA-based structure is one reason SEPs are often simpler to run, but they must still satisfy SEP-specific requirements under IRC § 408(k) to retain their tax benefits. Operational failures can create correction exposure and, in some cases, excise tax issues (for example, excess contributions).

Also, because SEP-IRAs are IRAs (not qualified-plan trusts), creditor/anti-alienation protections may differ from qualified plans and can be more limited in certain garnishment/creditor situations.

5. SIMPLE IRAs

A SIMPLE IRA is designed for smaller employers and allows employees to make salary reduction contributions while requiring the employer to contribute.

Under IRC § 408(p), a SIMPLE IRA plan is a written salary reduction arrangement under which eligible employees may elect to have the employer contribute amounts to a SIMPLE IRA instead of receiving those amounts in cash.

2026 limits and employer contributions

For 2026, employees may generally defer up to $17,000 to most SIMPLE plans and SIMPLE IRAs under IRC § 408(p)(2)(E) 11. SIMPLE IRA catch-up contributions under IRC § 414(v) are generally $4,000 for participants age 50 or older who do not attain ages 60–63 during the year, and $5,250 for participants who attain ages 60, 61, 62, or 63 during the contribution year.

Employers must generally either match employee deferrals up to 3% of compensation or make a 2% nonelective contribution for eligible employees.

Special early distribution rule

Like other IRAs, SIMPLE IRA distributions before age 59½ may be subject to the additional tax under IRC § 72(t). However, if a SIMPLE IRA distribution occurs during the first two years of participation, the early distribution tax increases from 10% to 25% under IRC § 72(t)(6).

Quick Comparison of Common Accounts

Retirement savings decisions are both tax and financial planning decisions. A CPA can help evaluate how each account type fits into your broader income tax, cash flow, and retirement strategy.
