On a tax return, PSO stands for Public Safety Officer. It’s a notation you add to Form 1040 to claim a federal tax break that lets certain retired public safety officers exclude up to $3,000 a year of their retirement plan distributions from taxable income, provided that money goes toward health or long-term care insurance premiums.1Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust The letters don’t appear pre-printed anywhere. If you see PSO on a completed return, someone typed it in to claim the exclusion.
What the Exclusion Is Worth
Retirement plan distributions are normally taxable. The PSO rule carves out an exception: a retired public safety officer can leave up to $3,000 of those distributions out of gross income each year, as long as the money pays qualified health insurance or long-term care insurance premiums. The cap is $3,000 or your actual premiums, whichever is smaller.1Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust
The premiums can cover you, your spouse, or your dependents. One catch: any amount you exclude here can’t also be claimed as a medical expense deduction on Schedule A.2Internal Revenue Service. Instructions for Form 1040 And only the portion of the distribution that would otherwise be taxable counts. If part of your payout is a return of your own after-tax contributions, that piece doesn’t qualify.1Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust
Who Counts as a Retired Public Safety Officer
Two things have to be true. You worked as a public safety officer, and you left that job either at normal retirement age or because of disability.1Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust Voluntary resignations before retirement age, for reasons other than disability, don’t qualify.
The IRS treats law enforcement officers, firefighters, chaplains, and members of rescue squads or ambulance crews as eligible public safety officers.3Internal Revenue Service. Publication 575 – Pension and Annuity Income
The plan matters too. Only governmental plans qualify, and they have to fall into one of these categories:
- A qualified trust under section 401(a)
- A section 403(a) annuity plan
- A section 403(b) tax-sheltered annuity
- A section 457(b) deferred compensation plan
Private-sector retirement plans are out, even if the work was public-safety in nature. The plan must be a governmental plan run by the employer you retired from.1Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust
Where PSO Goes on Form 1040
PSO lands in one of two spots, depending on how your retirement income is classified.
Pension or Annuity Income
Most retirees report distributions on line 5. Line 5a holds the gross amount, line 5b the taxable amount. To claim the exclusion, reduce the figure on line 5b by the excluded amount (up to $3,000) and check box 2 on line 5c. That box is specifically for the PSO exclusion.2Internal Revenue Service. Instructions for Form 1040
Disability Pension Before Minimum Retirement Age
If you retired on disability and haven’t yet reached the minimum retirement age set by your employer, the payments go on line 1h instead. Put only the taxable amount on line 1h, then write “PSO” and the excluded amount on the dotted line next to it.2Internal Revenue Service. Instructions for Form 1040
How to Claim It
Your Form 1099-R won’t do the math. The plan administrator reports the full distribution in box 1 and the taxable amount in box 2a without subtracting anything for insurance premiums. There’s no box on the 1099-R that separates out the premium portion.4Internal Revenue Service. Instructions for Forms 1099-R and 5498 You do the calculation yourself when you file.
The steps:
- Confirm you’re eligible: retired public safety officer, left because of disability or at normal retirement age, distribution from a qualifying governmental plan.
- Total the health and long-term care insurance premiums you paid during the year.
- Take the smaller of that total or $3,000. That’s your exclusion.
- Subtract the exclusion from the taxable amount in box 2a of your 1099-R, and report the reduced number on line 5b (or on line 1h for a pre-retirement-age disability pension).
- Check box 2 on line 5c, or write “PSO” next to line 1h.
The premiums can be paid two ways. The plan can send the money directly to your insurance provider, or the plan can pay you and you pay the provider. Either arrangement works.3Internal Revenue Service. Publication 575 – Pension and Annuity Income
If You See PSO on a W-2
PSO on a W-2 is a different situation and has nothing to do with the retirement exclusion. The IRS Box 12 codes are one or two letters (A through Z, then AA through HH), covering items like 401(k) deferrals or employer HSA contributions.5Internal Revenue Service. 2026 General Instructions for Forms W-2 and W-3 A three-letter code like PSO isn’t in that list.
If PSO appears on your W-2, it’s most likely in Box 14a, which employers use for miscellaneous items with whatever labels they choose. Typical Box 14a entries include state disability withholdings, union dues, uniform payments, and health insurance premiums.5Internal Revenue Service. 2026 General Instructions for Forms W-2 and W-3 PSO there is just an employer’s shorthand.
To find out what it means, check the back of the W-2 for a legend of custom codes, or ask payroll or HR. Whether the amount was already excluded from your Box 1 wages (as a pre-tax deduction) or is only informational determines whether it affects your return, so it’s worth clearing up before you file.
