Any distribution from a retirement account, pension or annuity is reported on this form, and the form alone does not tell you what is taxable.
One box carries most of the meaning: a code describing what kind of distribution it was. That code determines the treatment, and it is the part people skim past on the way to the amount.
This covers who issues the form, what each box reports, why the distribution code matters more than the rest of it, how the figures reach your return, and what to do when a rollover or a code has been reported incorrectly.
Form 1099-R is issued by financial institutions, employers, and insurance companies to report distributions from pensions, annuities, individual retirement accounts (IRAs), 401(k) plans, profit-sharing plans, and insurance contracts. If you received $10 or more from a retirement or insurance account during the year, you will receive a Form 1099-R. Understanding how to read and report this form correctly can prevent costly tax errors.
Who Issues Form 1099-R
- IRA custodians (banks, brokerages, mutual fund companies)
- Employer plan administrators (401(k), 403(b), 457(b) plans)
- Pension and profit-sharing plan administrators
- Insurance companies for annuity and insurance contract payments
- State and local government for pension distributions
One box decides most of the treatment on this form, and it is the one people skim past. If the code does not match what actually happened, take it up with the payer rather than reporting around it, because the figure they reported is the one that will be compared against your return.

How to Report Form 1099-R on Your Tax Return
The taxable amount from Box 2a flows to Form 1040, Line 5b (pension and annuity income) for pensions/annuities, or Line 4b for IRA distributions. The withholding in Box 4 is an additional tax payment credited against your total tax.
If Box 2b is checked (taxable amount not determined), you must calculate the taxable amount yourself:
- For traditional IRAs with nondeductible contributions: use Form 8606 to calculate the taxable portion using the pro-rata rule
- For Roth IRA distributions: use Form 8606 to determine whether the distribution is qualified (tax-free) or non-qualified (partially taxable)
Rollovers, The 60-Day Rule
If you receive a distribution and want to avoid taxation, you can roll it over into another qualified plan or IRA within 60 days. Key rules:
- One rollover per year per IRA (not per account, it is a per-taxpayer limit for IRA-to-IRA rollovers)
- Trustee-to-trustee transfers (direct rollovers, Code G) have no 60-day deadline and no one-per-year limit
- 20% mandatory withholding applies to eligible rollover distributions from employer plans, you must replace the withheld amount out of pocket to complete a full rollover
- If you miss the 60-day deadline without IRS-approved waiver reasons, the distribution becomes taxable (and potentially subject to 10% penalty)
Pro Tip: Always request a direct rollover (trustee-to-trustee) rather than taking a check. You avoid the 20% withholding, eliminate the 60-day risk, and get Code G on your 1099-R, which is clearly non-taxable.
Net Unrealized Appreciation (NUA)
If you received a lump-sum distribution from an employer plan that included your employer's stock, the NUA (the appreciation of the stock while in the plan) may qualify for preferential capital gains rates rather than ordinary income. Report NUA on Schedule D.

Frequently Asked Questions
I rolled over my 401(k) to an IRA. Why did I get a 1099-R?
All distributions, including rollovers, require a 1099-R. If the rollover was direct (Code G), the taxable amount in Box 2a should be $0. Report it on your 1040 with the rollover notation.
What if Box 2a is blank?
You must determine the taxable amount yourself, typically using Form 8606 for IRA distributions. Do not leave Line 4b/5b blank on your 1040.
I received Code 2, what exception applies?
The payer indicates Code 2 when it knows an exception applies (e.g., SEPP/72(t) distributions). If you believe Code 1 was wrong and an exception applies, use Form 5329 to claim the exception.
Are Roth IRA distributions ever taxable?
Yes, non-qualified Roth IRA distributions are partially taxable. A distribution is 'qualified' only if you are at least 59 1/2 AND the account has been open for at least 5 years. Otherwise, use Form 8606.
What is the 10-year forward averaging option?
Certain lump-sum distributions from qualified plans to participants born before January 1, 1936 may qualify for 10-year averaging, which can reduce the tax significantly. This is reported on Form 4972.
