Roth & Traditional IRA Limit Calculator (2026)

You can contribute the full $7,500 ($8,600 at 50 or older) if your modified AGI is below $153,000 (single or head of household) or $242,000 (married filing jointly). The amount shrinks across the next $15,000 (single) or $10,000 (joint) and is zero from $168,000 or $252,000. Married filing separately and living with your spouse at any time in the year, the range is $0 to $10,000.

Halfway through the single range (modified AGI $160,500) the limit is half: $3,750 for someone under 50 (Publication 590-A, Worksheet 2-2). Anything you contribute to a traditional IRA for the same year also comes off the Roth limit, because one limit covers both.

The limit is reduced by the share of the range your income has used: the limit × (modified AGI over the start ÷ width of the range). The reduction is rounded down to a multiple of $10, so the limit rounds up to one, and a limit that would fall under $200 stays at $200 until your income is past the range (26 U.S.C. 219(g)(2); Publication 590-A). Example: single, covered by a 401(k), modified AGI $85,000 → $7,500 × ($4,000 ÷ $10,000) = $3,000 off, so you can deduct up to $4,500.

The IRS worksheets are written with the 2025 amounts ($7,000 and a 70% or 35% multiplier). In 2026 the limit is $7,500, so the same method gives different percentages (75% for most filers, 37.5% for a covered joint filer); this calculator uses the statute's own ratio rather than those printed multipliers.

Yes, if your income is low enough. Being covered by a plan at work only limits the deduction when your modified AGI is above $81,000 (single or head of household) or $129,000 (joint). If you are not covered but your spouse is, the deduction is not reduced until a joint income of $242,000. If neither of you is covered, there is no income limit on the deduction. A contribution you can't deduct is still allowed, up to the same limit, as a nondeductible contribution reported on Form 8606.

Your Form W-2 has a “Retirement plan” box, which is checked if you were covered. In a defined contribution plan (a 401(k), profit-sharing plan, SEP or SIMPLE) you are covered for a tax year if money was contributed or allocated to your account for the plan year that ends in it, even if you have no vested interest; in a pension (defined benefit) plan, you are covered if you were eligible to take part. Social Security and railroad retirement are not coverage, and neither is drawing benefits from a former employer's plan (Publication 590-A, “Are You Covered by an Employer Plan?”).

For the traditional IRA deduction, it is your adjusted gross income (Form 1040, line 11a) worked out without the IRA deduction itself, plus the student loan interest deduction, the foreign earned income exclusion and housing exclusion or deduction, the savings bond interest exclusion and the employer adoption benefits exclusion (Worksheet 1-1). For the Roth IRA it is the same, except that income from converting a traditional IRA or rolling a workplace plan into a Roth IRA is left out (Worksheet 2-1). Because the IRA deduction itself is left out, the figure does not change with what you contribute.

Yes, on a joint return. The spouse with less pay can contribute up to the IRA limit if the couple's combined pay, less the other spouse's IRA contributions (traditional and Roth), covers it (the “Kay Bailey Hutchison Spousal IRA” limit in Publication 590-A). Example: one spouse earns $30,000 and puts $7,500 in an IRA; the other has no pay, and $30,000 − $7,500 still leaves room for their own $7,500. Whether each one's contribution is deductible is worked out separately, as above.

A direct Roth contribution is not allowed from the top of the range. A traditional IRA contribution still is, up to the limit, deductible or not depending on your coverage and income. Converting a traditional IRA to a Roth IRA is a separate move: a conversion does not count against the yearly limit (26 U.S.C. 408A(c)(5)), but the amount converted is taxable, to the extent it would have been taxed as a distribution (Publication 590-A). How much of a conversion is taxable depends on all your traditional IRA balances (Form 8606); this calculator doesn't work that out.

You can contribute for 2026 at any time in 2026 or by the due date of your 2026 return, not counting extensions (April 15, 2027 for most people). A contribution above your limit is an excess contribution: the IRS charges a 6% excise tax on it for each year it stays in the account. Withdrawing the excess and its earnings by the due date of the return (with extensions) avoids the tax, and an excess can be applied to a later year in which you have room (Publication 590-A).
