Updated October 16, 2026. Quick answer: Tied to federal. Iowa withholds from a resident’s pension or annuity when federal income tax is being withheld, and the 2026 IA W-4P says “Payers have the option of withholding at a rate of 3.8%”.
Iowa pension withholding at a glance
| Item | What the documents say |
|---|---|
| Is state withholding required on regular pension payments? | Tied to federal withholding: when federal tax is withheld, Iowa is withheld too, except on income not subject to Iowa tax and on a distribution of $500 per month or less (or a taxable amount of $500 or less) to a recipient eligible for the partial retirement exemption |
| Default rate if you give the payer no form | Payers may withhold at 3.8%, use the withholding formula, or use the withholding tables |
| Lump sum or one-time payment | For a lump-sum distribution from a qualified plan, Iowa tax is withheld to the extent federal tax is withheld, at 5 percent of the total distribution (or of the taxable amount, if known). The rule applies to distributions that are not transferred directly to an IRA, a section 403(a) annuity or another qualified plan, and it requires no withholding on a lump sum of $6,000 or less when the recipient is eligible for the partial retirement exemption and the lump sum is the only distribution from the plan that year |
| Form to start, change or stop it | IA W-4P (44-020), given to the person who handles your pension check |
| Changed for 2026? | No change stated |
What the Iowa documents say
Iowa’s administrative rule, 701 IAC 307.1(2), ties state withholding to federal: tax is withheld “when federal income tax is being withheld from the pensions or annuities”. The 2026 IA W-4P also says Iowa tax is not required to be withheld from qualifying recipients (age 55 or older, disabled, or certain survivors).
For the rate, the 2026 IA W-4P says “Payers have the option of withholding at a rate of 3.8%”. For a lump-sum distribution from a qualified plan, the administrative rule’s wording is “lump-sum distribution is 5 percent from the total distribution”.
To start or change withholding you give the IA W-4P to the person who handles your pension check; the form says to “Return the completed form to the person who handles your pension/retirement check”. You check the box saying you have no pension or annuity income subject to Iowa tax, or enter an additional whole-dollar amount to withhold from each payment.
What the printed rate means in dollars
For a pension of $2,000 a month if the payer uses the optional 3.8% rate: 3.8% of $2,000 is $76 (computed as $2,000 times 3.8%).
For a $50,000 lump sum withheld at the 5 percent the administrative rule prints: 5 percent of $50,000 is $2,500 (computed as $50,000 times 5 percent).
These are illustrations of the rate the state document prints, not a prediction of how your payer will calculate or what you will owe at filing.
What a mover should know
This page is about Iowa as a state of residence. An instruction line written for a nonresident or part-year filer is not the rule for a resident, and none of the documents read settles a part-year or two-state case, so check each state’s own rule. The federal side is the same everywhere; CMG’s federal 20% withholding on a pension lump sum page covers it, state tax withholding on IRA and 401(k) withdrawals in Iowa covers the account side, and state withholding on retirement withdrawals lists the other states checked.
What the documents do not say
- The two Iowa documents differ on the rate: the 2026 IA W-4P says payers may withhold at 3.8%, while the 2023 administrative rule text says 5 percent. The form is the later document.
Common mistakes
- Choosing no federal withholding and expecting state tax to be withheld anyway; in a state tied to federal withholding the two usually move together.
- Assuming the answer for one state applies to another, or that state withholding settles the state tax owed at filing.
