IRA Withdrawal Tax Calculator 2026

Enter your annual withdrawal amount, income, state, and age — the calculator shows your exact after-tax IRA income, the federal and state tax breakdown, early withdrawal penalty if you're under 59½, a Medicare IRMAA warning, the Social Security taxation interaction, and a 10-year balance projection.

How IRA withdrawals are taxed

Every dollar withdrawn from a traditional IRA or rollover IRA is treated as ordinary income in the year you take it — the same as wages or pension income. There is no long-term capital gains rate, no qualified dividends rate, nothing special. The taxes you deferred for decades come due at your ordinary marginal rate.

The federal calculation works in three steps:

1. Add the withdrawal to all other income. Your IRA withdrawal stacks on top of wages, pension, and — importantly — the taxable portion of Social Security benefits.
2. Subtract the standard deduction. For 2026: $32,200 for married filing jointly, $16,100 for single filers (IRS Rev. Proc. 2025-32¹).
3. Apply the 2026 brackets. Only the portion of income in each bracket gets taxed at that bracket's rate. A $60,000 IRA withdrawal doesn't mean everything is taxed at the rate of the top dollar — it's a staircase.

The calculator shows the federal tax attributable specifically to your withdrawal — the difference between your total tax with and without the withdrawal — which is the real cost of taking money out.

Early withdrawal penalty (under age 59½)

If you withdraw from a traditional or rollover IRA before age 59½, the 10% additional tax under IRC § 72(t)(1) applies on top of ordinary income tax. On a $40,000 withdrawal, that's $4,000 extra — before state taxes. There are 12 exceptions; the most commonly used are death, disability, SEPP/72(t) distributions, unreimbursed medical expenses exceeding 7.5% of AGI, and first-time homebuyer ($10,000 lifetime limit). See our IRA early withdrawal exceptions guide for the full list.²

Important: Rule of 55 does not apply to IRAs. The penalty-free access for employees who separate from service at age 55+ applies only to employer plans (401k, 403b, 457). Once you roll over to an IRA, that exception is gone. SEPP/72(t) is the IRA equivalent for pre-59½ access — see our 72(t) SEPP Calculator.

State income tax on IRA withdrawals

Nine states have no income tax at all: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Four more fully exempt IRA and retirement plan distributions: Illinois (despite a 4.95% income tax rate), Iowa (age 55+), Mississippi, and Pennsylvania.

In most other states, IRA withdrawals are taxable as ordinary income at the state's standard rates. California at 13.3% is the highest — a $100,000 annual IRA withdrawal costs an extra $13,300 per year just in state taxes, compounding over a 30-year retirement into hundreds of thousands of dollars. This asymmetry is why Roth conversion sequencing around a relocation to a low-tax state is a common advisor strategy. See the full state tax on IRA withdrawals guide for every state's exact rules.

The Social Security taxation interaction ("tax torpedo")

IRA withdrawals interact with Social Security benefits in a way that dramatically amplifies the real marginal tax rate. Here's how it works:

The IRS uses "provisional income" — your adjusted gross income plus 50% of Social Security benefits — to determine how much of your Social Security benefit is taxable. The thresholds (unchanged since 1984):³

• Single: PI below $25,000 = $0 taxable SS; $25K–$34K = up to 50% taxable; above $34K = up to 85% taxable
• MFJ: PI below $32,000 = $0 taxable SS; $32K–$44K = up to 50% taxable; above $44K = up to 85% taxable

The problem: a $1,000 IRA withdrawal pushes provisional income up by $1,000. If you're in the 50%-inclusion zone, that makes an additional $500 of SS taxable. At a 12% bracket, your actual marginal rate on that $1,000 becomes 12% × ($1,000 + $500) = $180, or an 18% effective rate. In the 85%-inclusion zone, the same $1,000 withdrawal triggers an additional $850 of taxable SS, creating an effective marginal rate of 22% × $1,850 = $407 on $1,000 — a 40.7% rate in a nominal 22% bracket.

This is the "tax torpedo" — and it's one of the strongest arguments for Roth conversions during the gap years between retirement and when Social Security begins.

Medicare IRMAA and IRA withdrawals

For Medicare beneficiaries, IRA withdrawals can trigger the Income-Related Monthly Adjustment Amount (IRMAA) — a surcharge on Medicare Part B and Part D premiums. IRMAA is based on your MAGI from two years prior (so 2026 Part B premiums are based on 2024 income).

The 2026 Tier 1 IRMAA threshold is $109,000 for single filers and $218,000 for MFJ (CMS.gov⁴). Crossing this threshold adds $81.20/month per beneficiary to Part B premiums — $974.40/year per person. For a married couple, crossing Tier 1 costs $1,948.80/year. The cliff is sharp: one dollar over the threshold triggers the full surcharge.

A large IRA withdrawal in a single year — from a Roth conversion, an RMD, or an emergency — can push income over an IRMAA tier. Advisors typically manage this by staging conversions across multiple years, using QCDs to satisfy RMDs without adding to MAGI, or timing large withdrawals to off years. See our Roth Conversion Calculator for bracket-by-bracket conversion planning.

RMDs are always included in this calculation

If you're 73 or older (born 1951–1959) or 75 or older (born 1960+), you have a required minimum distribution you must take before December 31. RMDs are ordinary income subject to all the same taxes above. Enter your total planned withdrawal — including the RMD amount — in the calculator above.

You cannot roll over an RMD amount. The RMD must be taken first; only the excess above the RMD can be rolled over or converted to Roth. See our IRA rollover and RMD rules guide for the sequencing rules, and our IRA RMD Calculator to calculate your required amount.

QCD: zero-tax withdrawals for charitable giving

If you're age 70½ or older, a Qualified Charitable Distribution (QCD) lets you transfer up to $111,000/year from your IRA directly to a qualifying charity — and exclude that amount from gross income entirely. A $30,000 QCD costs $0 in federal or state income tax and doesn't affect provisional income, meaning it won't increase taxable Social Security. QCDs can satisfy your RMD. See the QCD guide for mechanics.
