Texas TRS is one of the largest teacher pension systems in the country. If you're a Texas public school teacher, administrator, or education support staff member, TRS is almost certainly your primary retirement income. Here's how the math works.
The TRS benefit formula
Your annual benefit is: 2.3% x years of credited service x your highest average salary. Most members use their five highest annual salaries; grandfathered members (Tiers 1, 4 and 6) use their three highest.
A teacher with 30 years of service and a five-year average salary of $65,000 earns: 0.023 x 30 x $65,000 = $44,850 per year, or about $3,738 per month before any survivor benefit election.
Eligibility: age 65 and the Rule of 80
Texas TRS has several retirement eligibility paths depending on your tier and hire date.
Every member needs at least five years of service credit to retire. At 65 with five years, the benefit is unreduced.
Before 65, the Rule of 80 gives an unreduced benefit when your age plus years of service credit equal at least 80, but the minimum age depends on your tier. Tiers 1 and 2 have no minimum age, so a 57-year-old with 23 years qualifies. Tiers 3 and 4 need to be at least 60, and Tiers 5 and 6 at least 62. In Tiers 3 through 6, meeting the Rule of 80 below the minimum age means a reduction of 5% for each year under 60 or 62, though Tier 4 and 6 members who are at least 55 with 20 years aren't reduced. Tier 1 and 2 members with 30 years who retire before 50 lose 2% for each year under 50.
You can also retire early from 55 with five years, with a reduction from TRS's early-age tables. The Rule of 90 isn't a retirement rule: it's how non-grandfathered members (Tiers 2, 3 and 5) qualify for the PLSO.
TRS tiers and how hire date matters
Texas TRS has six tiers based on when you were hired and when you became a member. The main dividing lines are September 1, 2007 and September 1, 2014.
Tiers 1 and 2 (joined before September 1, 2007, with five years by August 31, 2014) have the most generous rules: the Rule of 80 at any age. Tiers 3 and 4 (membership began on or after September 1, 2007, with at least five years of service credit by August 31, 2014) need age 60 for an unreduced Rule of 80 benefit. Tiers 5 and 6 (joined on or after September 1, 2014, or with under five years on August 31, 2014) need age 62. Within each pair, the even or odd tier depends on whether you were grandfathered under the 2005 rules.
Know your tier. It sets when you can retire without penalty, how many salary years go into your average and whether you qualify for the PLSO. Log into your MyTRS account at trs.texas.gov to confirm your tier and service credit.
The Partial Lump Sum Option (PLSO)
Texas TRS doesn't offer a full lump sum the way corporate pension plans do under IRS Section 417(e). What it does offer is a Partial Lump Sum Option, or PLSO.
At retirement, eligible members can take 12, 24 or 36 months of their monthly benefit as a one-time payment, and the ongoing annuity is permanently reduced in exchange. Grandfathered members (Tiers 1, 4 and 6) qualify when they're eligible for an unreduced annuity. Non-grandfathered members (Tiers 2, 3 and 5) also need age plus service of at least 90.
Example: on a $3,000 monthly benefit, the 36-month PLSO pays $108,000 up front. TRS doesn't publish the reduction formula, so get the exact reduced monthly amount from MyTRS before you choose.
The PLSO makes sense in a few situations: you have high-interest debt to pay off, you want to fund a specific purchase at retirement, or you have reason to believe your life expectancy is shorter than average. For most healthy retirees, taking a permanent monthly reduction in exchange for a lump sum that depletes in 36 months is a bad trade.

No Social Security for most Texas teachers
Most Texas school districts do not participate in Social Security. That means teachers in those districts pay no Social Security payroll tax during their teaching years and accumulate no Social Security credits from that work.
TRS is your entire public retirement benefit. There's no SS check coming on top of it.
If you worked in Social Security-covered employment before or after your teaching career, you did earn SS credits. Those benefits were previously subject to the Windfall Elimination Provision (WEP), which could cut your earned SS benefit by as much as $557.50/month for someone who turned 62 in 2023. The Social Security Fairness Act, signed January 5, 2025, repealed WEP for benefits payable after December 2023. If WEP previously reduced your Social Security, you should now receive your full earned benefit plus retroactive payments back to January 2024. Use the WEP calculator to estimate the impact.
Survivor benefit options
At retirement, you choose your annuity option. The standard annuity pays the highest monthly amount but provides nothing to a beneficiary after you die. Option One continues 100% of your reduced benefit to your beneficiary, Option Five continues 75% and Option Two continues 50%.
The reduction for survivor protection depends on your age and your beneficiary's age. Younger beneficiaries produce larger reductions. In TRS's published factors, a 63-year-old naming a 59-year-old beneficiary under Option One (100% survivor) gets 88.64% of the standard annuity.
This is an irrevocable election made at retirement. Think carefully. The survivor benefit is life insurance built into your pension, and for couples where one spouse has significantly less retirement income, it's often worth the reduction.

Social Security Fairness Act: what Texas teachers get back in 2025 and 2026
The Social Security Fairness Act (Public Law 118-273) was signed into law on January 5, 2025, repealing both the Windfall Elimination Provision (WEP) and the Government Pension Offset (GPO). For Texas TRS members who also earned Social Security credits from private-sector or Social Security-covered public employment, this repeal is a meaningful financial improvement.
Under WEP, if you received a pension from non-covered employment (such as Texas TRS) and also had Social Security earned benefits, WEP reduced your Social Security check by up to $557.50/month if you turned 62 in 2023, and never by more than half your TRS pension. The repeal applies to benefits payable after December 2023. SSA sent the back payments, covering months from January 2024, as one-time payments starting in February 2025, and on July 7, 2025 said it had completed over 3.1 million of them.
Under GPO, surviving spouses and divorced spouses who received a government pension were subject to an offset that reduced or eliminated their Social Security spousal or survivor benefit. GPO affected many Texas teachers whose spouses had Social Security earnings -- it could reduce the spousal benefit by two-thirds of the TRS pension amount. That offset is also now eliminated. Surviving spouses of Texas teachers should contact the SSA to determine whether they are now eligible for restored or reinstated survivor benefits.
The practical implication for Texas teachers: if you have any Social Security credits from private employment, military service, or other Social Security-covered work, you should contact the SSA to understand how the repeal affects your benefit. The value adds up: $557.50/month restored for 20 years is $133,800 in additional lifetime Social Security income. If you were already collecting a reduced benefit, SSA adjusted it without an application. If you never applied because WEP or GPO would have erased the benefit, you need to apply now.
The cost of retiring early
The Rule of 80 lets some members retire unreduced well before 65, but every year you leave early is a year of service you don't earn. A Tier 1 or 2 teacher who retires at 55 with 25 years gets a smaller check than the same teacher retiring at 60 with 30 years. At a $70,000 average salary, those five extra years add 5 x 2.3% x $70,000 = $8,050 a year, about $671 a month, for life. That's before any raise in the salary average.
The 403(b) supplement
Texas public school employees can also save in a 403(b) through their district. The 2026 deferral limit is $24,500, or $32,500 with the age-50 catch-up (IRS Notice 2025-67). People aged 60 through 63 get a larger catch-up of $11,250, for $35,750 total.
The 403(b) gives you something TRS can't: money you can reach. Saving $500 a month for 25 years at a 5% return grows to about $298,000. Someone who puts in $32,500 a year for 10 years at 5% ends up with about $409,000.
Health coverage before Medicare
TRS-Care is the TRS health plan for eligible retirees, and TRS-ActiveCare covers working school employees. If you retire before 65, you'll pay for coverage until Medicare starts, and the premiums for retirees not yet on Medicare are higher than for those who are. Pull the current TRS-Care eligibility rules and premium sheet from trs.texas.gov before you pick a date. Seven or eight years of pre-Medicare premiums can eat a good part of what early retirement seems to gain.
Buying service credit
TRS lets members buy certain kinds of service credit, including some military service, out-of-state public school service and some leaves of absence, and members who took a refund can sometimes reinstate the service they gave up. Each type has its own cost rules. Every purchased year adds 2.3% of your average salary to the annual benefit: at a $72,000 average, that's $1,656 a year, or $138 a month. Ask TRS for a cost estimate through MyTRS and compare the price with the extra income before your retirement date.
Putting it together
A teacher who retires at 60 with 30 years and a $70,000 average salary earns $48,300 a year ($4,025 a month) from TRS. Add $1,200 a month of Social Security from summer and early-career jobs, claimed at 70, and the guaranteed income at 70 is $5,225 a month before any 403(b) withdrawals.
TRS has no automatic cost-of-living increase. The Legislature has to pass one, and it doesn't happen often. Social Security does adjust every year. If your pension stays at $4,025 for 20 years, the 403(b) is what absorbs inflation. Use the present value calculator to see what your TRS benefit is worth.
Leaving before retirement
Teachers who leave before retirement can usually leave their money in TRS as a deferred benefit or take a refund of their own contributions. The refund ends your TRS membership and every benefit tied to that service. The state and district money that funded part of your pension stays with TRS.
Run the numbers both ways. A teacher with 12 years and a $55,000 average who leaves at 40 has earned 12 x 2.3% x $55,000 = $15,180 a year, about $1,265 a month, payable unreduced at 65. A refund pays back only what you put in. Get both figures from MyTRS and remember the deferred benefit is a lifetime payment while the refund is a one-time check that's taxable unless you roll it over.
Disability and death benefits
TRS also pays disability retirement benefits and benefits to survivors of active members. The amounts depend on your service credit and the option chosen, so check the current TRS Benefits Handbook or MyTRS for your own figures.
Before you file
Log into MyTRS and check your service credit, your tier and your benefit estimate. Fix any missing service before your retirement date. If you have service you can buy, get the cost estimate. If the PLSO tempts you, get the reduced monthly figure in writing and compare. Request your Social Security earnings record if you have any covered work. Then pick the survivor option with your spouse in the room, because you can't change it later.
