A pension check looks like a paycheck, but the IRS treats it differently. Nothing is automatically withheld the way it was from your old job, and how much of it is even taxable depends on how the pension was funded.
This article walks through how pension withholding actually works, what can make part of your pension nontaxable, and the questions worth asking before your first tax season as a retiree.

How Pension Withholding Actually Works
If you don't submit a withholding form to your plan administrator, they still withhold federal tax from each payment, using a default rate the IRS sets. That default doesn't know your actual tax bracket, deductions, or other income, so it can end up withholding too much or too little.
Naming your plan administrator now makes the rest of this easier to act on.

How Much of Your Pension Is Actually Taxable
If your pension was funded entirely with pre-tax contributions from your employer, the full amount you receive is taxable. If you also put in after-tax dollars of your own, part of each payment can be a tax-free return of what you already paid tax on, figured using the method described in IRS Publication 575.
A quick monthly check helps you see whether your withholding is in the right range before it becomes an April surprise.

Total withheld each month: $220

Compare this to what you actually owed last tax season. If you owed noticeably more, ask your plan administrator to increase withholding with a new Form W-4P.
Questions Worth Asking Before You File
State tax rules for pension income vary widely. Some states don't tax pension income at all, others tax it the same as any other income, and a few tax it somewhere in between. Confirm your state's actual rule instead of assuming your pension is treated like your neighbor's.
A short list of questions keeps that first tax season from turning into guesswork.

Common questions
Is pension income automatically taxed like a paycheck?
No. Nothing is automatically withheld from a pension the way it was from a paycheck. If you don't submit a withholding form to your plan administrator, they withhold federal tax using a default rate that may not match your actual tax bracket, so it's worth checking and adjusting it yourself.
Is all of my pension taxable?
It depends on how the pension was funded. If it was funded entirely with pre-tax employer contributions, the full amount is taxable. If you also contributed after-tax dollars, part of each payment can be a tax-free return of what you already paid tax on, figured using the method in IRS Publication 575.
How do I change how much tax is withheld from my pension?
Submit a Form W-4P to your plan administrator. It lets you set or change your federal withholding instead of relying on the default rate. Ask your plan administrator for the current form and confirm how long it takes to take effect.
Does my state tax pension income?
It depends on the state. Some states don't tax pension income at all, others tax it like any other income, and some fall in between. Confirm your state's specific rule instead of assuming it works the way a friend's or a former neighbor's does.
