Roth IRA for teachers: when $8,600 a year beats the 403(b)

My pension covers me, so a Roth IRA adds nothing

A $4,200-a-month pension is $50,400 a year of income, and it's fully taxable at the federal level (state rules vary, so check yours). Subtract the $16,100 single standard deduction for 2026 and $34,300 is already taxable before a teacher draws one dollar from her 403(b).

A physician knows this problem from the other side. A bonus lands on top of salary, so it's hit by her highest bracket. A retired teacher has the same stacking in slow motion. The pension fills the lowest brackets first, so every 403(b) income draw lands above it, in brackets the pension has already pushed her into.

Required minimum distributions (RMDs) make it worse later. For anyone born in 1960 or later they start at age 75, and they force taxable draws from whatever is left in the 403(b), needed or not. Roth IRA money has no RMDs for the original owner, and qualified draws add nothing to taxable income. A pension can't give you that.

One limit applies. If your retirement income will clearly be lower than your salary (a small pension, years of part-time work, no Social Security yet), the 403(b) deduction at today's rate usually beats the Roth. Then Roth dollars are just tax paid early.

A Roth only makes sense when you're young and in a low bracket

Say it plainly: if your tax rate is 22% now and 22% later (for illustration), a pre-tax dollar and a Roth dollar end up the same. The Roth wins only when your later rate is higher, or when the pre-tax account costs more to hold. Yes, that means paying the tax now.

Keisha, 56, is a single high-school chemistry teacher with 29 years of service (hypothetical, round numbers). She's still paying into a 403(b) annuity with $640,000 in it, and she's deciding between retiring at 58 or 60. Her pension estimate is near $4,200 a month at 60. She has $8,600 a year to save, which over four tax years (56 through 59) is $34,400.

In the annuity, at 1.4% a year in costs, that money loses about $480 a year once it's all in ($34,400 × 1.4%). In a Roth IRA index fund at 0.1%, it loses about $34. On tax, at 22% now and 22% later, it's a tie: the 403(b) deduction saves her $1,892 a year now ($8,600 × 22%). The Roth wins if her rate after 60 is higher, and a fully taxable $50,400 pension plus RMDs can make that likely.

Before Harbourfront Wealth Management suggests sending new dollars anywhere, it puts the annuity's total yearly cost from the contract next to the index fund's expense ratio. Then it estimates her tax rate at 60 with the pension included. Surrender charges on her existing annuity money are a separate decision, covered in the site's 403(b) fee review service.

How big does this get as the balance grows? The cost gap and the tax at stake rise in step with it. Even the four-year $34,400 column matters, so the rule applies well below six figures. Growth is left out so you can check every cell.

Teachers married to a high earner can't use a Roth IRA

For 2026, the IRS phase-out for married couples filing jointly runs from $242,000 to $252,000 of modified adjusted gross income (MAGI). A teacher married to a physician or an executive can cross it without seeing it coming, because vested RSUs (company stock awards) count as wages in the year they vest.

So wait. Your household's MAGI isn't known until the year ends. You have until the tax-filing deadline the following April to make a Roth IRA contribution for the prior year. Waiting avoids an excess contribution, which carries a 6% excise tax every year the excess remains uncorrected.

Above the phase-out there's a backdoor route: a nondeductible traditional IRA contribution, then a conversion to Roth. The pro-rata rule counts the pre-tax money in all of your IRAs, including a rollover IRA, but not money in a 403(b) or 457(b). Rolling an old 403(b) into an IRA the same year can turn a tax-free backdoor into a mostly taxable one.

The spousal IRA helps in the other direction. A working teacher filing jointly can fund a Roth IRA for a spouse with no earned income, up to $8,600 each at 50 or older. Combined contributions can't exceed the couple's earned income, and the phase-out still applies to the joint MAGI.

Whether a high-earning spouse closes the door turns on one number, the household MAGI. For Keisha's married colleague, a $230,000 joint income plus $20,000 of vested RSUs puts the couple inside the $242,000-$252,000 range. That's why Harbourfront Wealth Management looks at the tax return before it looks at any account.

Can I still put money in a Roth IRA the year I retire?

Yes, as long as you had earned income that year. Salary from January to June counts, and you can contribute up to the limit or your earned income, whichever is lower. Pension payments and 403(b) income draws are not earned income, so contributions stop the first full year you're only drawing a pension, unless you work part-time.

A retirement date in June can still leave room for a full $8,600, if the salary you earned that spring is at least that much.

Set up a Roth IRA for teachers in this order

Step 1. Start with last year's MAGI from your tax return, then estimate this year's and compare it with the phase-out ($153,000 single, $242,000 joint). This year's income is what counts for this year's contribution, so add any raise, RSU vesting or spouse's bonus. Step 2. Pull your 403(b) statement or contract and write down the yearly fund and annuity charges. If they're above about 0.5%, new dollars usually belong elsewhere first.

Step 3. Open the Roth IRA with a low-cost custodian and pick one broad index or target-date fund. Check its expense ratio before the first deposit. The account doesn't invest your money until you choose a fund, and cash sitting idle is a frequent surprise.

Step 4. Set an automatic monthly transfer of about $717 ($8,600 ÷ 12) from checking, so the limit fills by December without a lump sum. Step 5. Keep each year's Form 5498 (custodians send it by the end of May) with your other documents. It's your record of contributions, and contributions can come out tax- and penalty-free at any time.

Step 6. Once a year, after the household's tax return is done, check that the contribution was allowed for that year's MAGI. Fix any excess before the filing deadline to avoid the 6% excise tax.

Our working order is this. Fund the Roth IRA first, up to $8,600 a year at 50 or older for 2026, if three conditions hold: your pension will cover half or more of your retirement spending, your 403(b) charges more than about 0.5% a year and your MAGI is under the phase-out. Then add pre-tax 403(b) dollars. Our guide on maxing out a 403(b) and 457(b) in one school year picks up from there.

Roth money is tax-free for good, so put everything there

Congress can change how accounts are taxed. Keeping both pre-tax and Roth money means a future change hurts only part of your savings, so don't stop pre-tax saving entirely to chase Roth.

Markets can bite too. A Roth IRA in stocks can fall, and you can get back less than you put in. Money you plan to draw in the first three years of retirement can sit in a steadier bond or cash fund inside the Roth.

Health is the third one. If illness pushes retirement from 60 to 58, Roth contributions end with the paychecks. Contributions can still come out tax- and penalty-free if cash runs short before the pension starts, but earnings are tax-free only after age 59½ and five tax years since the first Roth IRA contribution.

That clock leads to a quiet error. Putting off a first Roth IRA contribution costs nothing this year, but the five-year clock for tax-free earnings only starts with that first deposit. A teacher who makes her first one at 61 can't take earnings tax-free until about 66. Even $500 deposited now starts the clock.

Handle the Roth IRA deposits yourself, and bring the tax overlap to Harbourfront Wealth Management

Opening the account, setting the monthly transfer and choosing one low-cost fund are things most teachers can do alone in an evening. The part worth a conversation with Harbourfront Wealth Management is the overlap: your pension estimate, your 403(b) costs, a spouse's RSU income and your likely tax rate at 60, worked out together so the Roth dollars go where they save the most. Before any work begins, you'll see exactly what it costs in a written agreement.
