401(k), IRA and HSA contribution limits for FIRE savers: 2026 and 2027
Tax-advantaged accounts are the engine of most FIRE plans. Knowing the annual limits tells you how much of your savings rate can go into them before you need a taxable account. This guide lists the official 2026 limits published by the IRS, explains catch-up contributions, and notes the status of 2027 limits as of 11 November 2026. Always check the IRS pages linked below for the current figures.

What about 2027?
When we checked on 11 November 2026, the IRS had not yet published its notice setting 2027 limits for 401(k)s and IRAs. Last year the IRS announced 2026 limits in mid-November. Several actuarial firms and publishers have released projections, but projections are not official figures and we do not list them here. We will update this guide when the IRS publishes the 2027 numbers.
How the limits fit into a FIRE plan
Consider a single saver with a high savings rate. Maxing a 401(k) at $24,500, an IRA at $7,500 and an HSA at $4,400 shelters $36,400 a year in 2026 before any employer contributions. If that person saves $50,000 a year, the remaining $13,600 goes into a taxable account — which also happens to be useful for early retirement, because taxable accounts have no age restrictions on withdrawals.
For a married couple both working with access to workplace plans, the sheltered space roughly doubles. Employer matches add on top and count toward the $72,000 total-additions limit, not toward the $24,500 employee limit.
Traditional or Roth?
Many 401(k) plans offer both. Traditional contributions reduce taxable income now and are taxed on withdrawal; Roth contributions are taxed now and qualified withdrawals are tax-free. For FIRE planners, a mix can be useful: traditional contributions lower taxes during high-earning years, and later Roth conversions in low-income early-retirement years can move money into Roth accounts at lower tax rates. See accessing money before 59½ for how conversions interact with early access.
Roth IRA contributions are limited by income, and the IRS publishes the phase-out ranges each year. High earners sometimes use other routes, which have their own rules worth checking with the IRS or a professional.
Catch-up contributions for late starters
Catch-up contributions give people aged 50 and over extra room, and ages 60 to 63 get a higher catch-up in 2026 where the plan allows. For someone starting late, these can meaningfully shorten the path to Coast FIRE. A 55-year-old aiming at a $1,000,000 FIRE number at 65 needs about $613,913 invested to coast at a 5% real return, according to our Coast FIRE by age table. Adding $32,500 a year ($24,500 plus $8,000) to a 401(k) can close a gap quickly.
Separate rules apply to Roth IRA eligibility. The IRS 2026 news release sets the Roth IRA income phase-out range at $153,000 to $168,000 for single filers and heads of household, and $242,000 to $252,000 for married couples filing jointly. Within those ranges the amount you can contribute directly to a Roth IRA shrinks; above them it is zero.
HSAs as a stealth retirement account
HSAs are the only account that can be tax-deductible going in and tax-free coming out, when used for qualified medical expenses (IRS Publication 969). Some FIRE savers invest their HSA rather than spending from it, pay current medical costs from cash, and keep receipts to reimburse themselves later. After 65, non-medical withdrawals are taxed like a traditional IRA rather than penalised. Eligibility requires an HSA-eligible high-deductible health plan; check the rules before relying on this.
Priorities many savers use
There is no universal order, but a common sequence is:
- Contribute enough to the 401(k) to receive any full employer match.
- Fund an HSA if eligible.
- Fund an IRA (traditional or Roth depending on income and tax situation).
- Return to the 401(k) up to the limit.
- Invest the rest in a taxable brokerage account.
Early retirees often weight step 5 more heavily than traditional retirees, to build a bridge to 59½.
How limits affect your savings rate
When calculating your savings rate for the years to FI calculator, include pre-tax contributions and employer match in both income and savings. Otherwise a household maxing a 401(k) will appear to save less than it really does.
A worked example: what maxing accounts does to the timeline
Take a single saver with $100,000 of take-home pay plus $24,500 of pre-tax 401(k) deferrals, so $124,500 of income on our consistent definition. Suppose they defer the full $24,500, fund a $7,500 IRA and a $4,400 HSA, and invest $13,600 more in a taxable account: $50,000 saved, a savings rate of about 40%. On our years to FI calculator, a 40% savings rate from zero at a 5% real return and a 4% withdrawal rate gives about 22 years. If the same person saved only enough to capture an employer match and nothing else, the savings rate might be closer to 10%, and the same assumptions give about 52 years. The limits do not set your timeline, but they make a high savings rate more tax-efficient.
Watch the calendar
401(k) deferrals generally must come out of pay by year end, so if you want to raise contributions for 2026, payroll changes need to happen soon. IRA and HSA contributions for a tax year can generally be made up to the tax-filing deadline the following spring; check the IRS pages for the exact rules that apply to you.
Summary
For 2026, the IRS limits are $24,500 for 401(k)-type deferrals (plus $8,000 catch-up at 50+, or $11,250 at 60–63), $7,500 for IRAs (plus $1,100 at 50+), and $4,400/$8,750 for HSAs. 2027 limits were not yet published on 11 November 2026. Use the limits to plan which accounts receive your savings, and keep a taxable bridge if you plan to retire early. This guide is educational, not tax advice.
