The 2027 retirement contribution limits have not been published yet, but savers are already asking what they will be. The IRS has not released next year’s figures for 401(k) plans or IRAs, and the final numbers hinge on an inflation reading due in mid-October. Until then, everything about 2027 is a forecast.
That still leaves plenty to plan around. This year’s limits are official, several firms have published projections, and the rules for catch-up contributions have changed in ways that matter for anyone over 50. Canada and the UK also have their own allowances, with some dates coming up soon.
This guide separates what is confirmed from what is only expected. It covers the US first, then Canada and the UK. It is general information, not tax or investment advice.

What the 2027 Retirement Contribution Limits May Look Like
No official 2027 number exists yet, so treat every figure in this section as an estimate. Milliman, a benefits consulting firm, projected in its August update that the 401(k), 403(b) and 457 deferral limit could rise by $1,000, from $24,500 this year to $25,500 in 2027. Its earlier March forecast was lower, at $25,000, which shows how much the projection depends on inflation data.
The regular catch-up for people aged 50 and over could move from $8,000 to $8,500 in the higher scenario, or stay at $8,000 in the lower one. Milliman’s March forecast also put the age 60 to 63 super catch-up near $11,750. For IRAs, one planning site estimates the limit could climb from $7,500 to $8,000, but that is a single estimate, not a consensus.
If the inflation reading comes in low, the lower figures apply. If it comes in higher, the larger increases are likelier. Either way, the official announcement is the only number to rely on.
The Confirmed 2026 Limits to Use as a Baseline
For 2026 the IRS confirmed that the 401(k), 403(b), governmental 457(b) and Thrift Savings Plan limit is $24,500, up $1,000 from 2025. The IRA limit is $7,500. The catch-up limit for people aged 50 and over in workplace plans is $8,000, up from $7,500.
A newer rule gives people aged 60 to 63 a higher “super” catch-up of $11,250 instead of the standard $8,000, if their plan offers it. Plans are allowed to choose whether to include it, so check with your plan administrator. For someone in that age band, one source puts the combined workplace-plan maximum at $35,750.
Those numbers are your working baseline for the rest of this year. Anything you contribute before 31 December counts against the 2026 limits, whatever 2027 turns out to be.
Why the 2027 Retirement Contribution Limits Are Not Set Yet
The IRS adjusts most retirement limits for inflation, and the key input is the September consumer price reading, which is scheduled for release on 14 October. Limits are usually announced afterwards, in late October or early November. The 2026 limits were announced on 13 November 2025, so a mid-November date is possible again.
Limits also move in steps, not smoothly. Most 401(k) amounts are rounded to the nearest $500, so a small rise in prices may give no increase, while a slightly larger one gives $500 or $1,000. That rounding is why forecasts for 2027 have bounced between $25,000 and $25,500.
Because of this, there is little value in a decision that depends on guessing the exact figure. Plan around the 2026 limits and adjust when the 2027 limits are published.
Catch-Up Contributions and the Roth Rule
Catch-up contributions let people aged 50 and over save more than the standard limit. The 2026 amount is $8,000, with the higher $11,250 for ages 60 to 63. These amounts sit on top of the regular deferral limit.
There is also a rule for higher earners: those whose prior-year wages from their employer passed a threshold must make catch-up contributions as Roth contributions, not pre-tax. Sources disagree on the exact threshold, with one citing $145,000 and another $150,000, so confirm the current figure in the IRS regulations or with your plan.
The practical point is that catch-up money may be taxed now, not later, depending on your pay. If you are close to the threshold, talk to your plan administrator or a tax professional before you change your contributions.
IRA Limits and Income Phase-Outs
The 2026 IRA limit is $7,500. Whether you can contribute to a Roth IRA depends on your income. For 2026 the Roth phase-out 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.
A traditional IRA deduction can also phase out if you or your spouse are covered by a workplace plan. For 2026 the range is $81,000 to $91,000 for single filers covered at work, and $129,000 to $149,000 for joint filers where the contributing spouse is covered.
These ranges usually move up a little each year, so expect higher 2027 ranges when the IRS publishes them. Contributions to an IRA for a tax year can generally be made until the tax filing deadline of the following year, so you do not have to rush.
How the 2027 Retirement Contribution Limits Compare in Canada and the UK
In Canada, the Canada Revenue Agency’s published table shows an RRSP dollar limit of $35,390 for 2027, up from $33,810 in 2026. The limit is 18% of the prior year’s earned income, up to that cap, so many people will not reach the maximum.
The TFSA is less clear. The 2026 TFSA limit is $7,000. One bank table lists $7,000 for 2027, while another source projects $7,500 from the indexation formula. The CRA normally confirms the figure in the fall, so wait for that announcement.
In the UK, the annual ISA allowance is £20,000, and changes to cash ISAs are planned from April 2027. The Autumn Budget on 28 October could revisit the rules, according to one commentary. Pension annual allowance and ISA rules differ from the US system, so check official UK government pages for current figures.
How to Plan Around the 2027 Retirement Contribution Limits
Start with what you control. Check how much you have contributed this year and how much room is left under the 2026 limits. If your employer matches contributions, make sure you are capturing the full match, since that is part of your compensation.
Next, spread contributions across the year rather than waiting for a single large deposit. Automatic payroll deferrals do this for you. When the IRS announces the new limits, update your percentage or your dollar amount in January, not before.
Finally, think about where the money goes after you contribute. A retirement account is a wrapper, and what sits inside it matters. Our guide to CDs and high-yield savings accounts covers the cash side, while the choice between stocks and crypto is covered in crypto or stocks for beginners. None of this is a recommendation for your situation.

Final Thoughts
The 2027 retirement contribution limits will probably be a little higher than this year’s, but nobody knows by how much until the IRS publishes them. The sensible move is to use the 2026 limits now and avoid guesswork.
Rules and numbers change, and personal tax situations differ, so check the official figures from the IRS, the CRA or your own government and speak to a qualified adviser before you act.
