A required minimum distribution (RMD) is a mandatory withdrawal from certain tax-deferred retirement accounts. The distribution is generally included in taxable income, so its tax cost depends on other income, filing status, federal tax rates, state taxes, and whether it makes more Social Security benefits taxable. This calculator estimates federal and state tax associated with an RMD and shows the estimated amount left after those taxes.
With the default inputs, the RMD is $25,000, other taxable income is $30,000, the federal tax rate is 22%, and the state tax rate is 5%. The calculator estimates $5,500 of federal tax and $1,250 of state tax, for total tax of $6,750. The effective tax rate on the RMD is 27%, and the estimated amount remaining is $18,250.
This is a simplified estimate, not a tax return calculation. It applies the selected federal bracket and state rate to the RMD rather than modeling every progressive tax bracket, deduction, credit, or state rule. For RMD deadlines and eligibility, use the RMD age calculator or review RMD rules explained.
Enter Income and Tax Assumptions
Enter the RMD amount, age, filing status, other taxable income, federal tax bracket, state tax rate, and annual Social Security income. If you enter an account balance and age 73 or older, the calculator may estimate the RMD from the account balance using an age-based divisor instead of using the entered RMD amount. With the default account balance of $0, it uses the entered $25,000 RMD.
Other taxable income matters because it can affect whether some Social Security benefits are taxable. The calculator estimates that additional effect by comparing taxable Social Security with and without the RMD. The defaults include $0 of Social Security, so there is no extra Social Security tax effect in the example.
Use a current estimate of your marginal federal rate and state tax rate. A marginal rate is the rate applied to the next dollar of taxable income; it is not necessarily the effective rate on all income. For an RMD amount calculation, use the RMD calculator. For withholding choices, compare with the RMD tax withholding calculator.
Default Example: $25,000 RMD
The federal estimate is $25,000 × 22% = $5,500. The state estimate is $25,000 × 5% = $1,250. Combined tax is $5,500 + $1,250 = $6,750. Net after tax is $25,000 − $6,750 = $18,250. Effective tax rate is $6,750 ÷ $25,000 = 27%.
The result is not a prediction of the exact tax bill generated by taking an RMD. The calculator’s federal estimate applies the chosen bracket directly to the distribution. Actual federal income tax is calculated using progressive brackets and taxable income after deductions and other adjustments. Your RMD can also interact with capital gains, tax credits, Medicare premiums, and other income-based thresholds.
| RMD amount | Federal rate | State rate | Estimated federal tax | Estimated state tax | Combined estimate |
|---|---|---|---|---|---|
| $12,500 | 22% | 5% | $2,750 | $625 | $3,375 |
| $25,000 | 22% | 5% | $5,500 | $1,250 | $6,750 |
| $37,500 | 22% | 5% | $8,250 | $1,875 | $10,125 |
These rows use the calculator’s flat-rate method and vary only the RMD amount. They do not model extra Social Security taxation; that component is $0 in the default result because Social Security income is set to $0.
Formula: Estimate the Tax and Net Amount
federal tax on RMD = RMD amount × selected federal tax rate
state tax on RMD = RMD amount × selected state tax rate
total tax estimate = federal tax + state tax + estimated federal tax on additional taxable Social Security
net after tax = RMD amount − total tax estimate
effective tax rate = total tax estimate ÷ RMD amount × 100
For the supplied defaults:
- Federal tax = $25,000 × 0.22 = $5,500.
- State tax = $25,000 × 0.05 = $1,250.
- Additional Social Security tax = $0, because the entered Social Security income is $0.
- Total tax = $5,500 + $1,250 + $0 = $6,750.
- Net after tax = $25,000 − $6,750 = $18,250.
- Effective rate = $6,750 ÷ $25,000 × 100 = 27%.
The result’s effective rate can exceed the selected federal bracket because it combines the federal and state estimates. A 22% federal rate plus a 5% state rate yields 27% under the calculator’s assumptions; actual deductible state taxes and federal tax rules may change the result.
Tax Rules and Planning Choices
Most pre-tax Traditional IRA and workplace-plan RMDs are taxable as ordinary income. The taxable amount may be smaller if an account includes nondeductible contributions or after-tax basis, but basis tracking rules apply. Qualified Roth IRA distributions are generally tax-free, and the original Roth IRA owner does not have lifetime RMDs.
RMD timing matters because deferring the first RMD until April 1 can place two RMDs in one tax year. That may raise taxable income and affect Medicare’s income-related monthly adjustment amount (IRMAA), which generally uses tax-return income from two years earlier. The standard Medicare Part B premium is about $185 per month in 2026, but IRMAA can increase premiums for higher-income beneficiaries. Check current thresholds at Medicare.gov.
A missed RMD can trigger an excise tax generally equal to 25% of the shortfall. If corrected within the applicable correction window, the rate may be reduced to 10%. A waiver may be requested for reasonable error and corrective action. Learn how to reduce taxes on RMDs and review tax-efficient withdrawal options.
| Choice | Potential advantage | Tradeoff to test |
|---|---|---|
| Withhold taxes from the RMD | Pays part of the tax as the distribution occurs | Reduces cash received |
| Take additional tax withholding from another payment | May help meet withholding needs | Can affect cash flow elsewhere |
| Take the first RMD in the age year | May spread income across two calendar years | Requires a distribution earlier |
| Delay the first RMD to April 1 | Keeps more money invested temporarily | Can create two RMDs in one year |
A qualified charitable distribution may count toward an eligible IRA RMD when made directly to a qualifying charity, subject to age and tax rules. It is not a general tax-free option for every retirement account or recipient. Confirm eligibility with the custodian and tax professional before arranging a transfer.
Next Steps: Move from Estimate to Tax Plan
Enter your current filing status, state rate, Social Security, and other income rather than relying on defaults. Confirm the required distribution amount and first-year deadline with the custodian. Compare a withholding plan with the RMD tax withholding calculator and include pension, investment, and Medicare costs in a full-year projection. The calculator is a useful tax-planning screen, but it does not replace a complete tax return estimate.
Frequently Asked Questions
Quick answers to the questions people usually have after running the retirement calculator.
1Is the entire RMD taxed at my federal bracket?
Often, a pre-tax RMD is included in ordinary taxable income, but the final tax is based on your full tax return. The calculator applies one selected bracket to the RMD for an estimate; it does not reproduce progressive tax calculations or all deductions and credits.
2Why is the effective rate 27% when my federal bracket is 22%?
The calculator adds a 5% state tax estimate to the 22% federal estimate. In the default example, $5,500 plus $1,250 is $6,750, and $6,750 divided by $25,000 is 27%. Your actual combined burden may differ.
3Can an RMD make my Social Security taxable?
Yes, an RMD can raise provisional income and cause a larger portion of Social Security benefits to be taxable. The calculator estimates this effect when Social Security income is entered, but the estimate is not a full tax projection.
4Should I take my first RMD early or delay until April 1?
Taking it in the year you reach the starting age may spread income across two tax years. Delaying can put two RMDs in the following year and increase that year’s taxable income. Compare both calendar years, including potential Medicare premium effects, before deciding.
5Does a Roth IRA have a taxable RMD?
The original owner of a Roth IRA has no lifetime RMD. A designated Roth workplace account also has no lifetime RMD for the original owner beginning in 2024. Inherited Roth accounts can have distribution requirements, and their tax treatment depends on the beneficiary rules.
6What if the calculator says my RMD is too high?
If you entered an account balance, verify the prior December 31 balance, age, account type, and divisor. A dollar estimate can be wrong if an input is wrong or an exception applies. Confirm the custodian’s calculation and use the RMD calculator for a separate check.
Social Security and the RMD Tax Interaction
Social Security benefits can become partly taxable when provisional income exceeds thresholds set by federal law. Provisional income generally includes adjusted gross income, tax-exempt interest, and half of Social Security benefits. An RMD can raise this amount, potentially making a larger share of benefits taxable.
The calculator estimates taxable Social Security with and without the RMD, then adds the federal tax effect of the change. In the default example, annual Social Security income is $0, so the reported taxable Social Security amount is $0. If Social Security is entered, the estimate still remains simplified: the tax effect is calculated using the selected federal bracket, not a full tax return.
Use an earnings-based benefit estimate from SSA.gov, then consider the tax interaction with a Social Security claiming-age guide. A tax projection should also include pension income, investment income, deductions, and filing status. For broader income planning, compare with a monthly retirement income calculator.
