Opting Out of the Teachers' Pension and Rejoining

The short version of a longer problem

Teachers opt out of the Teachers' Pension Scheme for understandable reasons. Contributions of between 7.4% and 12% of salary are a visible, recurring deduction on a payslip at a time when almost every other cost has risen, and the benefit they buy is decades away and impossible to see. When money is tight, the pension line is one of the very few large outgoings a teacher can switch off unilaterally and immediately.

The problem is that the decision is presented as a simple trade — this much money now, that much pension later — when it is actually four separate decisions bundled together. You are giving up the pension you would have built. You are giving up an employer contribution worth several times your own. You are giving up death and survivor cover with immediate effect. And, if the break runs long enough, you may be permanently changing how the pension you have already built is calculated, which is the part almost nobody sees coming.

This page sets out all four, along with the mechanics of getting out and getting back in. It is not an argument that nobody should ever opt out — there are real situations where it is defensible — but it is an argument that almost everyone who does it is working from an incomplete picture of what it costs.

How opting out actually works

The process itself is short, which is part of the trouble. You complete an opt-out form and give it to your employer, who acts on it through payroll and notifies Teachers' Pensions. There is no cooling-off conversation, no requirement to take advice, and no stage at which anyone is obliged to explain the consequences set out on this page.

The one piece of timing that catches people is when contributions actually stop. They stop from the month after the form is received — not the month you signed it, and not the month you posted it. In practice this means at least one further full contribution will be taken after you have made the decision, and possibly several if the form takes time to reach the right person. If you are opting out for cash-flow reasons and expecting the saving to appear in a particular month, build that lag into your planning.

Refunds: the three-month window and what follows it

Whether you get your money back depends almost entirely on how quickly you act, and the window is much shorter than most people assume.

Rejoining is not automatic

This is the single most important operational fact on this page, and it is responsible for more accidental pension loss than any deliberate decision.

Opting out is a standing instruction. It does not lapse when you change school, change employer, change contract, return from a career break or decide in your own mind that you would like to be back in. To rejoin the Teachers' Pension Scheme you must complete an Election to join the Teachers' Pension Scheme form and give it to your employer. Until that form is processed, you are not a member, however long you have been teaching and however much you intended to rejoin.

The good news, and it is genuinely good news, is that the route back is otherwise unrestricted. Teachers' Pensions answers the question directly in its opting-out FAQs: "Yes, you can Opt out and re-join whenever you'd like and as many times as you'd like." There is no waiting period, no minimum time out, no medical underwriting, no penalty rate and no probationary period. A teacher who left the scheme in 2009 can rejoin tomorrow on exactly the same terms as one who left last term, and Teachers' Pensions actively encouraged opted-out members to consider rejoining in a news item published in November 2025.

What there is, is a form. And the practical failure mode is almost always the same: a teacher opts out during a difficult year, intends to rejoin "once things settle down", and then discovers at retirement that four or seven or eleven years went by without the election ever being made. Nothing in the payroll process prompts it. The only reliable safeguards are your employer's automatic re-enrolment cycle, discussed below, and your own diary.

The real cost: the disqualifying break

Everything above is administration. This section is the reason the page exists, because it describes a cost that is invisible at the point of decision, falls on pension you have already earned, and can run to tens of thousands of pounds.

An opt-out creates a break in pensionable service. The Teachers' Pension Scheme treats breaks in service differently depending on length, and the dividing line is five years. Teachers' Pensions' own Breaks in Service factsheet is unusually precise about it, and unusually precise in both directions: a disqualifying break for the final salary link occurs when you are out of pensionable service for more than five years and return on or after 1 April 2015, and — the reassuring half — "If you've a break in pensionable service of five years or less you'll not lose your final salary link."

There is a second, slightly different five-year test that applies to McCloud-era transitional protections, where the qualifying return date is on or after 1 April 2012 rather than 2015. Both use the same "more than five years" threshold, so for practical purposes there is one line to watch — but if your circumstances turn on it, the two tests are separate and worth checking individually.

A disqualifying break changes two things permanently.

One: it breaks the final salary link

If you have service in the final salary schemes — the 1/80th scheme for pre-2007 entrants, or the 1/60th scheme for those who joined between 2007 and 2015 — the value of those benefits depends on your final average salary, which is normally calculated at the point you eventually retire. That is why a teacher who was on the main pay range in 2014 but retires as a deputy head in 2035 gets their pre-2015 service valued at deputy head money. The link between old service and eventual salary is the most valuable single feature of final salary pension.

A disqualifying break severs it. Return to pensionable service after a break of more than five years and your final salary benefits are calculated using your salary at the date the break began, not the salary you go on to reach. The service is not lost — it is still there, and it is revalued for inflation in deferment — but it stops tracking your career.

Two: it changes how your career average pension grows

The second effect applies to everyone, including teachers with no pre-2015 service at all, and it starts immediately rather than after five years.

Career average pension already accrued does not sit still. It is revalued each year, and the rate depends on your membership status. An active member — someone in pensionable service — has their accrued career average pension revalued at the Treasury Order rate plus 1.6 percentage points. A member who is not in pensionable service has it revalued at the Treasury Order rate alone.

That 1.6% is not a rounding error. It is one of the most valuable features of the career average scheme, and it is the mechanism that stops a career average pension being worth dramatically less than a final salary one. Opting out switches it off for every year you are out, and the effect compounds across the whole of your accrued pension, not just the part you would have added.

A worked illustration of the cliff edge

Consider a teacher with £12,000 a year of career average pension already accrued, twenty-six years from retirement, who is thinking about opting out. The figures below are illustrative and assume a Treasury Order rate of 2.5% throughout, purely to isolate the effect of the 1.6 percentage point difference. They look only at what happens to the pension already earned — they ignore entirely the pension not accrued during the break, which is an additional and separate loss.

Read the last two rows together, because that comparison is the entire argument of this page. Five years out costs this teacher around £2,540 a year of pension. Six years out costs them around £11,300 a year. The sixth year of the break is, in this illustration, more than four times as expensive as the first five combined — not because of anything that happens during that year, but because crossing the five-year line switches the pension earned before the break onto the lower revaluation rate permanently, for the remaining twenty years of the teacher's career and beyond.

Now add the other two layers on top. Six years of accrual at 1/57th of, say, £45,000 would have added roughly £790 a year of pension for each year missed, revalued thereafter. And because six years is more than five, the break is disqualifying for the final salary link too: if the same teacher also held pre-2015 service, that service is now pinned to the salary they were on when the break began rather than the salary they eventually reach.

The practical takeaway is precise rather than general. If you have any pre-2015 service and you are going to opt out, treat five years as a hard deadline. A break of four years and eleven months and a break of five years and one day are not roughly the same decision. They are different decisions with permanently different outcomes, and the only thing separating them is a date you control.

What you lose the moment you opt out

The revaluation and final salary effects are slow. The death and survivor cover effect is instant, and it is the one that most deserves a conversation at home before the form is signed.

An active member of the Teachers' Pension Scheme who dies in service leaves their family a death grant of three times salary, with no minimum qualifying period, plus short-term and long-term survivor pensions calculated on an enhanced in-service basis. A teacher on £45,000 is carrying roughly £135,000 of life cover that costs them nothing extra and that they will never see on a payslip.

Opt out, and that is gone from the month your contributions stop. Depending on your service history you may hold deferred member death benefits instead, but those are calculated on a completely different and far less generous basis — for a career average member, a death grant of 2.25 times the accrued pension rather than three times salary, and a survivor pension without the in-service enhancement. The full comparison is set out in our guide to Teachers' Pension death benefits, which covers the in-service, deferred and post-retirement positions side by side.

Teachers' Pensions itself puts this at the top of its opt-out page, though it frames it as a list of benefits to consider rather than a warning about what disappears. Among the benefits of membership it asks you to weigh before opting out are "a death grant for a nominated person, or your partner or your estate if you die before retirement" and "a pension for your partner and any dependant children if you die before or after retirement". Those two lines are the ones worth reading twice.

• The in-service death grant of three times salary stops. There is no partial or reduced version for opted-out members, and no option to pay to keep it.
• Enhanced in-service survivor pensions stop. A surviving spouse, civil partner or qualifying partner falls back onto the deferred basis, which produces a materially smaller pension.
• Ill-health retirement cover stops. Ill-health benefits are a benefit of active membership; a deferred member's position if they become too ill to work is significantly weaker.
• You cannot elect any of the scheme flexibilities. Faster Accrual, Additional Pension and Buy Out all require you to be in pensionable service to apply, so opting out closes those doors for the duration.

Automatic re-enrolment every three years

One safety net exists, and it is worth understanding both because it may rescue you and because it may surprise you.

Under automatic enrolment law, employers must re-enrol eligible jobholders who have opted out back into a qualifying pension scheme approximately every three years. The employer chooses a re-enrolment date within a window around the third anniversary of their previous staging or re-enrolment date, and on that date staff who meet the eligibility criteria — broadly, aged between 22 and State Pension age and earning above the earnings trigger — go back in automatically.

Two consequences follow. The first is reassuring: an opt-out is never permanent by default. If you do nothing, you will be put back into the scheme within about three years, and the drift that costs teachers so much is at least bounded. The second is that if you genuinely intend to stay out, you must actively opt out again at each cycle, and you may find contributions restarting without warning if you have forgotten the date.

The employer contribution you are declining

Any honest assessment of the cost of opting out has to include the part of the package you are handing back.

The employer contribution rate to the Teachers' Pension Scheme in England and Wales is currently 28.68% of pensionable pay, confirmed to fall to 17.68% from 1 April 2027 following the 2024 scheme valuation. Against a member contribution of between 7.4% and 12%, that means for every £1 you put in, your employer is putting in roughly £2.40 today — and even after the 2027 reduction, still considerably more than you contribute yourself.

That money does not follow you if you opt out. It is not paid to you as salary, it is not held for you, and there is no equivalent arrangement offered instead. The comparison people instinctively make — "I could invest this myself" — understates the gap by a factor of three, because the amount they would be investing is their own contribution alone.

There is also the tax point, which is frequently overlooked. Teachers' Pension contributions are deducted under a net pay arrangement, so relief is given at your marginal rate automatically through payroll. A basic-rate taxpayer contributing 9.9% of salary sees a net cost of about 7.9%; a higher-rate taxpayer contributing 11.8% sees a net cost of about 7.1%. The figure on the payslip is not the figure leaving your pocket, and for higher-rate taxpayers in particular the real cost of membership is meaningfully lower than the headline rate suggests.

Two opt-out traps that are not this one

"Opting out" describes at least three different situations in teaching, and confusing them leads people to the wrong advice. It is worth being precise about which one you are in.

• The voluntary opt-out described on this page. You are employed by a school or trust that participates in the Teachers' Pension Scheme, you are eligible, and you choose to leave. This is the scenario where the five-year disqualifying break rule, the three-month refund window and the Election to join form all apply as described.
• The independent school phased withdrawal trap. Independent schools leaving the scheme can use a phased withdrawal, under which existing staff stay in and new staff do not. The trap there is quite different: a teacher at such a school who opts out, even briefly, can find they cannot get back in, because rejoining would count as a new entry to a scheme the school has closed to new entrants. Our guide to independent schools and the TPS covers that mechanism in full — if you work in an independent school, read it before doing anything.
• Academy conversion. This is not an opt-out at all. Academies remain participating employers in the Teachers' Pension Scheme, your membership continues uninterrupted, and no break in service arises. Our guide to academy conversion and the TPS explains why the five-year break rule does not bite on conversion, which is a common and unnecessary worry.

Alternatives worth considering first

If the reason for opting out is affordability rather than principle, there are options that cost less than leaving the scheme entirely. None of them is a complete answer, but each is worth checking before signing a form.

• Check your contribution tier is right. The tiers are based on actual pensionable pay, and errors happen — particularly for part-time staff, teachers whose hours have changed mid-year, and anyone whose TLR or allowance has ended. Being in the wrong tier is not rare and correcting it is free.
• Consider reducing hours rather than leaving the scheme. Contributions are a percentage of pensionable pay, so working fewer hours reduces them proportionately while keeping you in pensionable service — which preserves the death cover, the revaluation rate and the final salary link. It is the only way to cut the contribution without any of the consequences on this page.
• Look at the whole payslip before the pension line. Where a school offers salary sacrifice arrangements for cars, cycles or technology, those change take-home pay without touching pension membership. Our guide to salary sacrifice schemes in schools explains the trade-offs, including the effect some arrangements have on pensionable pay.
• Check your tax code. An incorrect tax code is a surprisingly common cause of a payslip that looks unaffordable, and fixing it is faster than any pension decision. Our guide to teacher tax codes covers how to check.
• If the issue is an Annual Allowance charge rather than cash flow, look at Scheme Pays first. Opting out to avoid a tax charge is a drastic response to a problem the scheme has a designed solution for. Our Annual Allowance guide explains the options.
• Talk to your union before deciding. All the main teaching unions employ pension specialists, membership includes access to them, and they see the full range of situations. This is precisely the kind of decision that benefits from someone who has seen it go wrong.

If you are going ahead anyway

Sometimes the decision is the right one, or simply unavoidable. If so, these are the steps that limit the damage.

• Fix a rejoining date before you submit the form, put it in a calendar with a reminder, and tell someone else about it. The drift is the danger, not the decision.
• If you have any pre-2015 service, treat five years as an absolute limit. Crossing it converts a recoverable pause into a permanent change to benefits you already own.
• Get written confirmation of the date your employer received the form, since that is what determines when contributions stop and whether any refund window applies.
• Do not take a repayment of contributions without thinking about qualifying service, particularly if you are anywhere near the two-year threshold or expect to return to teaching.
• Review your life cover. You are removing three times salary of death-in-service cover. If you have dependants, price the replacement before you lose it, not after.
• Diarise your employer's re-enrolment date so that restarting contributions is a choice rather than a surprise — and so that, if you have changed your mind by then, you simply let it happen.
• Check your record when you rejoin. Breaks are exactly the kind of event that produces gaps in a service record, and only your employer can correct one. Our Benefit Statement guide explains how to check and what evidence to keep.

The underlying point is that opting out is reversible in principle and frequently irreversible in practice. The scheme imposes no waiting period and no penalty on returning; the damage is done by time passing while nobody fills in a form, and by breaks that quietly cross a five-year line nobody mentioned. Both of those are within your control, but only if you know they exist before you start.
