The tax-free Lump Sum Allowance conundrum

In his debut article for Monevator, new contributor The Engineer ponders the imponderable: should he take his tax-free lump sum from his pension before the chancellor potentially takes the perk off him?

Hold onto your hats: it’s Budget season once more! Where will the tax axe will fall this time: rental income, pension tax relief, property, capital gains, or inheritance?

Pick your poison punters.

The contender that has generated the most column inches is the potential curbing or demise of the 25% tax-free pension lump sum – the beloved pot at the end of the long slog of a working life rainbow that is all yours to keep, unmolested by HMRC.

Generally, the advice from the experts is it’s foolish to second guess the chancellor and take drastic steps with your personal finances based on rumours. More specifically, it’s that you shouldn’t take your tax-free cash unless you already have a plan to spend it on something sensible like paying off the mortgage [1] or giving it to your kids.

But ever more people are ignoring that advice. They are grabbing the tax-free cash while they can.

As This Is Money reports [2]:

Mounting fears of further changes to pension rules in the upcoming Autumn Budget are pushing more savers to withdraw from their retirement pots, figures show.

The investment platform Bestinvest said it saw a 33% rise in withdrawal requests from customers with self-invested personal pensions or SIPPs in September […]

Bestinvest said the recent withdrawals were largely made up of those aged over 55 accessing their 25% tax-free cash lump sum, amid concerns that Chancellor Rachel Reeves may slash the tax-free withdrawal allowance.

I too am weighing up the pros and cons.

The media debate is mostly an emotional one. “The government’s going to rob me!” versus “Pensions are great! They’re tax-free!”

However I’m not sure either of those claims is true.

Monevator readers will demand a more sober analysis. Here is my attempt.

Wealth warning and disclaimer Everyone’s tax situation is famously individual, and your pension is a super-valuable and usually irreplaceable asset. This article is not personal financial advice – it’s just one man’s musings about his own situation. Seek professional advice as needed.

A sober analysis of the Lump Sum Allowance

The question under the microscope: in what circumstances would it make sense to take your tax-free lump sum out of your defined contribution (DC) pension and then invest it outside of the pension?

The crux? That future growth on my lump sum could be taxed outside of the pension – ISAs notwithstanding – but would compound tax-free while it’s still inside.

Then again, any growth inside a pension might still get taxed on withdrawal [3].

Hence we need to compare:

against…

The sheer number of factors at play is mind-boggling. Any attempt at a general analysis is doomed to die in a morass of imponderables.

But maybe we can look at it one factor at a time? Then we can at least establish some guidelines that might help us reach a decision.

For a start, we’ll assume that all pension and tax rules remain unchanged for the duration. (Although we will come back to this.)

Effective tax rate INSIDE the pension

Let’s assume your pension has already reached the old Lifetime Allowance (£1,073,100) and therefore the maximum possible tax-free lump sum (£268,275), now known as the Lump Sum Allowance (LSA [4]).

In this case all future growth inside the pension will be taxed on the way out. If you expect to be a basic-rate taxpayer at the point of withdrawal, say, then this will mean tax at 20%.

Remember this is the effective tax rate on the future growth in the pension. Not necessarily on the whole pension.

I’m assuming here that you don’t have any protected allowances.

Your going rate

It’s unlikely that your marginal tax rate will be lower than 20% later in retirement. The state pension is already using up pretty much all of the personal allowance, pushing most people into the basic-rate band on any additional income.

But it’s possible you expect to be a higher-rate or even additional-rate taxpayer in retirement.

Maybe you have a huge DC pension with protected allowances? Or a defined benefit pension (DB) as well as the DC pension. Or you’ll inherit a trust fund from great uncle Bertie.

In those cases the effective tax rate on growth inside your pension is going to be a lot higher.

Below the LSA

If you have yet to reach the LSA, then 25% of future growth will be tax-free (until you do hit the maximum).

For our analysis, we can think of this as two separate pots:

This approach reflects the fact that if you were to take out the tax-free lump sum, then the remaining 75% would be taken into drawdown and all subsequent withdrawals taxed at your nominal rate.

So, whilst the rate of tax on the growth of the pension as a whole would be 15% for a basic rate taxpayer (that is, 75% of 20%), the tax on the growth of the 25% lump sum can be considered as 0%.

And an effective tax rate of 0% is hard to beat!

Effective tax rate OUTSIDE the pension

The effective tax rate on growth of a lump sum held outside of a pension is even harder to tie down.

If you have spare ISA allowance [5], then the effective tax rate on the growth of whatever you manage to squirrel away into it would be zero.

Similarly, it would be zero if you have enough spare tax allowance to accommodate all the future growth, in whatever form.

As for tax rates:

Most probably your effective tax rate outside of a pension will be a combination of more than one of these, depending on your asset mix. In this case the rate will land somewhere in the middle.

Or perhaps it’ll be something very different if you’re prepared to take on truly esoteric tax planning.

What could be – ahem – simpler?

Comparing the tax rates

Obviously, if withdrawing the tax-free lump sum is going to work then I need to keep the effective tax rate on growth outside of the pension below the effective rate inside.

If you’re below the LSA, then you can’t beat the 0% effective tax inside a pension. The best you could do is match it with spare ISA and tax allowances.

If you’re above the LSA then some further thinking is needed.

The graph below shows the value of £1,000 lump sum invested outside a pension for 20 years (Y-axis), with a 7% growth rate, assuming varying effective tax rates on that growth (X-axis):

[9]

Here we’re comparing that lump sum growth (cyan line) against the same £1,000 tax-free lump sum held inside the pension and subject to a 20% tax on the growth when its withdrawn (pink line).

Again, note this is the tax rate on the growth only. The original sum is still tax-free whenever you decide to take it out. And we’re only thinking about the tax-free part of the current pension here.

So… eureka! With a lower tax rate the lump sum withdrawn will be worth more later!

“No shit, Sherlock“, I hear you cry.

Ah but it’s not quite that simple. You’ll see the lines in our graph don’t cross at 20%. Even if we have the same effective tax rate both inside and outside the pension, the lump sum outside the pension still loses.

Taxing matters

This is because there is a cost [10] to paying tax as you go along, versus paying just once at the end. (It’s for the same reason that annual fees are so insidious.)

More graphs required, clearly.

Below the difference for the same £1,000 tax-free lump sum is illustrated for varying investment durations – that is, how long the money is invested for before being needed – and again assuming 7% growth and an effective tax rate of 20% both inside and outside the pension:

[11]

And now for a varying growth rate assuming a 20-year investment duration:

[12]

This shows that the damage done to your lump sum outside the pension grows with time and growth rate. It arguably suggests that high-growth long-duration investments are best left inside the pension.

But wait! That high growth and long duration might mean you end up paying a higher tax rate on withdrawal from the pension.

So perhaps it’s better to get it out early?

Also, I’ve assumed capital gains tax is paid each year. Whereas in fact it could be left to accumulate and be paid at the end of the period. Although that too might not be a good idea.

Enough! I have fallen into that morass of imponderables. Let’s just say that you’re going to need to see some clear daylight between the effective tax rates to make withdrawing fly.

Asset allocation

Some of this discussion on tax rates has implications for asset allocation.

If you have spare ISA or tax allowances, then the world is your oyster. Fill your boots with any asset class you fancy.

If, however, you’re trying to minimise your tax rate by allocating to higher dividend-paying assets or direct holdings in low coupon gilts, then you’re making decisions on asset allocation.

And it’s almost certainly not wise to change your asset allocation solely to get that clear daylight between effective tax rates.

If you were already planning to include higher dividend assets or gilts in your portfolio then great. Move that part outside of the pension.

Otherwise, best to knock the whole thing on the head. 

Inheritance

The tax-free inheritance of pensions will be gone [13] by 2027.

This swings the pendulum a long way towards taking the lump sum sooner. Indeed it’s what has driven much of the increase in debate on this subject.

If you die before 75 then your heirs [14] would currently inherit your pension tax-free. Any tax you’ve paid on a lump sum outside of the pension would have been wasted.

But I wouldn’t be surprised if this perk too is axed at some point. And in any case, you’ll be dead!

If you die after 75 then your heirs would pay tax on their inherited pension. In this case, if it made sense to take the lump sum when you were alive, then it will still make sense when you’re dead.

So not much to sway us either way here.

Known unknowns

Some things could change in future that would make me regret taking my lump sum early.

Such as:

Conversely, some things could change that would make me feel extra warm inside because I already have my lump sum tucked away in a GIA:

Our soaring national debt makes it hard to imagine that pension rules will get more generous. So on balance, the second set of risks seem more likely to materialise than the first.

That’s not to say that any of these will happen this November. It’s unlikely that the government would suddenly introduce a cliff edge cut to the tax-free allowance, say.

But neither do I think the issue will go away. Somehow, sometime, by a government of one colour or another, I believe it’s probable that pension tax relief will become less generous.

A tax increase on unwrapped assets would be a blow but it’s just as likely that the tax on pension income will be increased. Still, it’s another risk to keep in mind when looking at your relative effective tax rates.

The conclusion

If you think the government is out to get you then you should probably take the lump sum early.

Use it to buy gold bars and guns. To keep in your cabin in the woods.

Otherwise, if you’re still below the Lump Sum Allowance, then you should probably leave the lump sum in the pension, although you shouldn’t lose out if you take the cash and have enough spare ISA and/or tax allowances to accommodate it.

Even if you’re already over the LSA, in my opinion it would probably only make sense to take the lump sum early if:  

This list is not definitive.

You don’t necessarily need all these to be true to make it worthwhile. Conversely, even if they are all true you might sensibly still not want to take the tax-free lump sum now.

You could wait a while and think about it later. The situation probably won’t change drastically in November.

(Probably.)

Decision time for yours truly

Of course it depends on your situation, but the arguments for withdrawal seem to stack up for me. That’s because I’m already at the maximum tax-free lump sum allowance and it makes sense for me to keep this part of my portfolio in gilts.

Even in the absence of any adverse tax changes, if I manage my tax carefully, I should still be up on the deal. And if – or more likely when – the pension tax axe falls then I’m supremely indifferent.

But before I push the Button of No Return, I’ll wait for any comments from you guys.

It’s quite possible the Monevator regulars will point out the flaws in my logic, and I will appear foolish.

Just as the experts in the media forewarned.

We’re certain to get new – even contrary – points raised by sharp Monevator readers in the comments. So even if you’re not a regular commenter, be sure to come back and check them out in a few days.
