How to Use the Pension Tax Comparison Calculator
When you retire, one of the most important decisions you'll face is how to receive your pension or 401(k) savings — as a single lump sum or as regular annuity payments. The tax implications are significant. Taking a large lump sum can push you into a much higher bracket for that year, while annuity payments spread out the income and potentially keep you in a lower bracket throughout retirement.
Lump-Sum Tax Considerations
A traditional 401(k) or pension lump-sum distribution is taxed as ordinary income in the year you receive it. If your balance is large, this could temporarily push you into the 32%, 35%, or even 37% federal bracket. A 10% early withdrawal penalty also applies if you're under 59½, unless exceptions apply.
Annuity Tax Considerations
Annuity payments are taxed as ordinary income each year, but spread out over many years. This typically keeps you in a lower tax bracket, especially if your other retirement income (Social Security, part-time work) is modest. The total tax paid over the annuity's life is usually less than a lump-sum's tax.
The IRA Rollover Option
A third option: roll the lump sum directly into a traditional IRA. This is not a taxable event. You keep tax-deferred growth and control when you take distributions — ideally in years when your tax rate is lowest. Many retirees prefer this flexibility over a fixed annuity schedule.
Frequently Asked Questions
Yes, in most states. Some states exempt pension income partially or fully, particularly for public employees. This calculator covers only federal tax. Check your state's rules before making the lump-sum vs annuity decision.
Traditional IRA and 401(k) accounts require minimum distributions starting at age 73 (as of 2023 law). RMDs are taxable income. Rolling into a Roth IRA avoids RMDs since Roth accounts have no RMD requirement.
