The confusion starts with the form itself. Box 1 shows the gross distribution, Box 2a may show a taxable amount, and a distribution can be reportable even when it is partly or fully tax-free. A rollover is the classic case.
This guide walks through the workflow: identify the distribution type, move the gross and taxable amounts to the right lines, enter withholding, then check whether Form 8606 or Form 5329 applies.
Key Takeaways
- Report Form 1099-R amounts even when nontaxable, such as a properly completed rollover.
- Box 1 is not automatically taxable; compare Boxes 2a, 2b and 7.
- IRAs use lines 4a/4b; pensions and annuities use 5a/5b.
- Roth conversions, inherited accounts, basis and early withdrawals may need extra forms.
What Is Form 1099-R and Which Boxes Matter?
What Form 1099-R reports
Form 1099-R reports distributions from:
- IRAs, pensions and annuities
- Qualified employer plans, section 403(b) and governmental 457(b) plans
- Profit-sharing plans and insurance contracts
Separate forms cover some federal retirement systems, such as the CSA-1099-R and RRB-1099-R. Those are outside this guide.
Receiving the form does not tell you how much is taxable. Keep it with your other income records.
Reading the key boxes
The 2026 recipient form works like this:
- Box 1: total amount distributed during the year.
- Box 2a: the amount generally taxable, as determined by the payer.
- Box 2b: a checkbox for "taxable amount not determined" and another for "total distribution" (the account was closed out).
- Box 4: federal income tax withheld.
- Box 7a: distribution code(s).
- Box 7b: the IRA/SEP/SIMPLE checkbox.
Common Box 7 codes:
- 1: early distribution, no known exception.
- 2: early distribution, exception applies.
- 4: death.
- 7: normal distribution.
- G: direct rollover to a plan or IRA.
- H: direct rollover from a designated Roth account to a Roth IRA.
- Q: qualified Roth IRA distribution.
- Y: qualified charitable distribution (optional for payers).
The full list is in the IRS recipient instructions, and it changes, so check the current year's version.
If you received several 1099-Rs, match each one to its account statement. Confirm the IRA/SEP/SIMPLE box is checked correctly, because that box decides which lines you use.
Where Do You Report Form 1099-R on Form 1040?
Reporting an IRA distribution on lines 4a and 4b
Line 4a takes the gross IRA distribution and line 4b the taxable portion. Don't treat Boxes 1 and 2a as interchangeable. Per the Form 1040 instructions, a fully taxable IRA distribution goes on line 4b only, with 4a left blank.
The taxable amount can be lower than the gross amount in these cases:
- After-tax basis: nondeductible contributions need Form 8606.
- Qualified Roth IRA distributions: not subject to tax or penalty.
- IRA rollovers: check the box on line 4c (box 1); a full rollover generally means zero on 4b.
- Qualified charitable distributions (QCDs): enter the total on 4a, enter zero on 4b if the whole amount was a QCD, and check line 4c (box 2).
You need records to back up any nontaxable portion.
Reporting a pension or annuity distribution on lines 5a and 5b
Employer pensions, annuities and employer-plan distributions go on line 5a (gross) and line 5b (taxable). A fully taxable amount goes on 5b only. For an employer-plan rollover, enter Box 1 on 5a, subtract the rollover to get 5b, and check line 5c (box 1).
The taxable part depends on how your after-tax cost is recovered:
- Simplified Method: mandatory for most qualified-plan pensions that started after November 18, 1996, if you were under 75 or had fewer than 5 years of guaranteed payments.
- General Rule: required for nonqualified plans such as purchased commercial annuities.
Publication 575 covers both.
Reporting federal withholding
Box 4 goes on line 25b, "Federal income tax withheld from Form(s) 1099." Attach the Form 1099-R if tax was withheld. Add up your Box 4 amounts across all forms and compare them with the payer's year-end statement.
Claiming withholding does not replace reporting the distribution itself. You do both.
A simple reporting example
This is a hypothetical with illustrative figures only, not advice for every taxpayer.
Maria receives a pension payout with Box 1 of US$24,000, Box 2a of US$18,000 and Box 4 of US$2,400. The US$6,000 difference is her recovered after-tax cost.
| Form 1099-R | Form 1040 |
|---|---|
| Box 1: US$24,000 | Line 5a: US$24,000 |
| Box 2a: US$18,000 | Line 5b: US$18,000 |
| Box 4: US$2,400 | Line 25b: US$2,400 |
How Common Form 1099-R Distributions Affect Reporting
Direct rollovers
A direct rollover usually carries code G (or H for Roth). The administrator pays the receiving plan or IRA directly, with no withholding. You still report the gross amount, and the taxable amount is generally zero.
Confirm the money went to an eligible account. Also check that nothing was paid to you or withheld.
Indirect rollovers
In an indirect rollover, you receive the money and must deposit it within 60 days. The IRS rollover rules add two traps:
- Withholding shortfall: employer-plan payments to you carry mandatory 20% withholding. To roll over the whole amount, you must replace the withheld sum from other funds.
- The one-rollover rule: generally one IRA-to-IRA rollover per 12 months across all your IRAs. It doesn't cover trustee-to-trustee transfers or Roth conversions.
The IRS example: on a US$10,000 distribution with US$2,000 withheld, rolling over only US$8,000 leaves US$2,000 taxable, and possibly subject to the early-distribution tax.
Roth IRA distributions and Roth conversions
A qualified Roth distribution may be tax-free. A Roth conversion is different: the amount converted from a traditional IRA is reported on line 4a, and the taxable portion is worked out on Form 8606 and carried to 4b.
Use Form 8606 for nondeductible contributions, basis, conversions and distributions from IRAs with basis.
Qualified charitable distributions
A QCD appears on Form 1099-R as an ordinary distribution, but it can be excluded from income. Requirements:
- You are at least 70½ when the distribution is made.
- The IRA trustee sends the money directly to an eligible charity.
- The 2026 annual exclusion limit is US$111,000 (US$108,000 for 2025).
You get no charitable deduction for the excluded amount. Keep the charity's acknowledgement.
Early distributions, inherited accounts and plan loans
- Early-distribution codes: code 1 signals possible additional tax. Code 2 signals an exception, but you should still confirm it.
- Inherited accounts: death is an exception to the 10% tax (code 4), but that doesn't make the distribution tax-free.
- Plan loans: code L is a loan treated as a distribution. Code M is a plan-loan offset, which can often be rolled over by the return due date, including extensions.
Form 5329 is the usual place to claim an exception or calculate the additional tax.
How Taxability, Withholding, and Penalties Work
Gross versus taxable distribution
The taxable amount depends on account type, contribution source, basis, age, beneficiary status and transaction details. Treat Boxes 2a and 2b as starting points. You remain responsible for checking whether the payer got it right.
When Box 2a is blank or marked undetermined
If "taxable amount not determined" is checked, the payer lacked the information. You work out the taxable amount using:
- Form 8606 and your basis records
- Annuity rules in Publication 575
- Other IRS worksheets
Don't enter zero because the box is blank. Ask the payer for clarification, or get professional help.
Federal withholding and estimated tax
Box 4 is a prepayment, not the final tax on the distribution. The default for IRA payments on demand is 10% withholding, and you can change it with Form W-4R. Eligible rollover distributions paid to you carry 20% mandatory withholding, which you can raise but not lower.
If withholding falls short, you may owe tax and a penalty unless you make timely estimated payments.
Early-distribution additional tax
Distributions before age 59½ generally face an extra 10% tax, or 25% for a SIMPLE IRA within its first two years. Exceptions include:
- disability or death,
- substantially equal periodic payments,
- first-home purchase (up to US$10,000 lifetime),
- birth or adoption,
- terminal illness,
- domestic abuse victims,
- emergency personal expenses.
Claim these exceptions on Form 5329. A Box 7 code alone does not prove or disprove that the additional tax applies. A TIGTA audit of tax year 2021 found about 2.8 million taxpayers with roughly US$12.9 billion in early distributions who didn't pay the additional tax or file Form 5329.
State reporting and recordkeeping
State rules differ from federal ones. New York, for example, lets qualifying taxpayers aged 59½ or older exclude up to US$20,000 of pension and annuity income on the state return. That is not a federal rule.
Keep these records:
- Form 1099-R, including any corrected versions,
- account statements and rollover confirmations,
- basis records and Forms 8606 until all IRA distributions are made,
- withholding details,
- charitable receipts.
The usual retention period is three years from filing.
Common Form 1099-R Mistakes and When to Get Help
Frequent errors include:
- Treating Box 1 as taxable without review
- Putting an IRA distribution on the pension lines
- Leaving out a nontaxable rollover
- Forgetting Box 4 withholding
- Missing Form 8606 or Form 5329
- Ignoring a corrected 1099-R
If a correction changes a filed return, file Form 1040-X.
Before filing, run this checklist:
- Match every 1099-R to a line on the return.
- Check the gross and taxable columns separately.
- Confirm the Box 7 codes and the IRA/SEP/SIMPLE box.
- Reconcile withholding to line 25b.
- Keep support for every nontaxable amount.
Inherited accounts, multiple rollovers, cross-border situations and unclear basis are where returns get complicated. That risk is higher for Australians holding US retirement accounts.
