Is TRS Retirement Taxable in Texas? Federal Tax, State Tax, and PLSO Rules

The Short Answer

Your TRS monthly pension is exempt from Texas state income tax — Texas has no personal income tax. But it's fully subject to federal income tax. Every monthly annuity payment TRS sends you is federally taxable, and you control how much gets withheld through your Form W-4P election.

Setting Up Federal Withholding

When you file Form TRS 31 (Application for Service Retirement), you also complete a federal tax withholding form — either Form W-4P or the TRS equivalent through the MyTRS portal. This tells TRS how much federal tax to withhold from each monthly payment before it hits your bank account.

You can adjust your withholding at any time after retirement through MyTRS. Many retirees start with a conservative withholding rate and adjust after their first full tax year, once they see how their total retirement income — TRS pension, Social Security, investment withdrawals, part-time work — stacks up.

If you under-withhold and owe a large balance at tax time, the IRS may assess an underpayment penalty. If you over-withhold, you get a refund but lose the use of that money throughout the year. A CPA can help you dial in the right number based on your complete income picture.

PLSO Lump Sum: Where the Tax Trap Lives

The Partial Lump-Sum Option adds a separate tax event on top of your monthly pension. If TRS pays the PLSO directly to you as a cash distribution, federal law requires TRS to withhold 20% for taxes immediately — before the money reaches you.

If you're under age 59½ at the time of distribution, the IRS may also apply a 10% early withdrawal penalty on the taxable amount. That penalty is separate from the 20% withholding and is not automatically withheld as another 10%.

The solution: direct the PLSO into an eligible retirement account through a trustee-to-trustee rollover. Traditional IRA, 403(b), or 457(b) plans all qualify. The money moves directly from TRS to the receiving institution, deferring tax and avoiding the immediate 20% withholding and early-withdrawal penalty on the rolled amount. You pay taxes later when you withdraw from the rollover account, on your own schedule.

You can split the PLSO — roll part over and take part in cash. The cash portion still triggers 20% withholding.

What About a 403(b) Rollover?

If you've been contributing to a 403(b) or 457(b) through your school district, those accounts have their own tax rules at retirement. You can roll a TRS PLSO into one of these accounts, and you can roll the 403(b)/457(b) balance into an IRA or other qualified plan.

For a TRS PLSO, use an eligible direct trustee-to-trustee rollover to defer tax and avoid the mandatory 20% withholding. For a 403(b) or 457(b) balance, confirm the rollover process with that plan's administrator.

Planning Ahead

Texas's lack of state income tax is a genuine advantage in retirement — your TRS pension stretches further here than an identical pension in California or New York. But federal taxes still take a meaningful bite, especially in the first year when a PLSO distribution can push you into a higher bracket.

Get your withholding right from the start. The Texas TRS Retirement Guide covers the tax withholding setup process and PLSO rollover coordination, including the specific lines on Form TRS 31 where you designate your rollover institution.
