How business owners can use SIPPs to build wealth

Every few years, usually after a particularly punchy tax bill, a business owner has the same thought: I appear to be doing quite well, so why do I feel faintly mugged?

You build the thing, nurse it through lean years, finally turn a proper profit – and then discover that moving money from "company" to "me" is less a transfer and more a ritual sacrifice.

There is, thankfully, a slightly more civilised route.

It does involve paperwork, patience and a willingness to think in decades rather than quarters, but if executed correctly it can stop the bleed.

What a SIPP actually is

The "civilised route" in question is a Self-Invested Personal Pension. Yes, a pension. Stay with me.

At its core, a SIPP is simply a pension with a longer investment menu. It is still a defined contribution arrangement. You put money in, it gets invested, and what you eventually take out depends on how much went in, how it performed and what it cost you in charges. There are no guarantees hiding in the paperwork.

What makes it interesting to business owners is the control and the tax treatment. Compared with many standard personal pensions, a SIPP usually offers a wider range of investments. You can run it yourself, leave it on a default setting, or even pay an adviser to manage it for you.

The real engine, though, is the tax wrapper. Contributions attract tax relief within the annual limits, and investments inside the pension grow broadly sheltered from UK income tax and capital gains tax. That combination is where the wealth-building potential sits.

Why directors and the self-employed tend to like them

So far, so orthodox. Nothing here to frighten your accountant.

Where SIPPs become genuinely useful is when you're both the shareholder and the person deciding what to do with the profits.

In practice, two features do most of the work:

Lever one: the company pays

Your company can usually pay into your pension directly as an employer contribution. Instead of paying yourself extra salary or dividends and then losing a slice to personal tax, the company sends the money straight into the SIPP.

Provided the contribution is genuinely for business purposes – reasonable pay for the work you do and not some disguised attempt to move money around – it's normally treated as a business expense.

That reduces the company's taxable profit before corporation tax is calculated. Less profit on paper, less corporation tax due.

You also avoid triggering income tax and National Insurance on yourself at the point the contribution is made, because the money never passes through your personal bank account.

That is the first lever.

Lever two: let the compounding commence

Once the money's inside the pension, the taxman largely steps back.

You get tax relief on what you put in, up to the annual allowance, which for 2025/26 is £60,000 for most people. Higher earners can see that allowance reduced, and anyone who has already started drawing flexibly from a pension may be limited to £10,000 a year. The detail matters, but the headline is simple: there is a ceiling.

Within the confines of that ceiling, investments can grow, produce income, and be sold without you paying income or capital gains tax year after year. That lack of annual tax drag is where much of the long-term advantage sits.

The catch is access.

You cannot decide next spring that you'd rather use it for a new warehouse, a morale-boosting piano no one can play, or buying your love rival's business out of spite.

For most people the money is locked away until at least age 55, rising to age 57 from April 2028.

Which is why SIPPs tend to suit owners who have profits they can genuinely spare. If every pound is earmarked for expansion, stock or averting sleepless nights, tying it up will feel restrictive.

Getting money in: company versus personal

For employees, pension funding is usually a payroll exercise. For owners, it's a decision.

There are two routes.

The company pays

The company can contribute directly to your SIPP as an employer contribution.

As we've already mentioned, the payment reduces the company's taxable profit, which lowers its corporation tax bill, and it does not trigger income tax or national insurance on you at the time. The deduction is generally given when the money is actually paid, not merely accrued, and unusually large contributions can have their relief spread.

For many directors, this is the most efficient way to move profit into long-term capital.

You pay personally

If you fund the SIPP yourself, the provider usually adds basic-rate relief automatically. Higher-rate relief has to be claimed through your tax return.

But, there is a ceiling tied to your salary.

You can normally only receive tax relief on personal contributions up to 100% of your "relevant UK earnings" for the year. In practice, that means salary or trading profits. Dividends don't count.

So if you pay yourself a modest salary of, say, £12,000 and take the rest of your income as dividends, you cannot personally pay £40,000 into your pension and expect tax relief on the whole amount. The relief is limited by that £12,000 salary figure.

That is the dividend trap.

Employer contributions avoid it, because the earnings cap applies to personal contributions, not to what the company can pay into your pension. The overall annual allowance still applies, but the salary restriction falls away.

The allowances

This is the part people skim, right up until the year they sell something, land a chunky contract, or accidentally have a very good twelve months.

For 2025/26 the standard annual allowance sits at £60,000 which is the broad headline limit on how much can go into your pensions in a single tax year without inviting an annual allowance tax charge.

Exceed it and the excess is, in effect, clawed back through your tax return; nothing theatrical, just a slightly sour line item.

If your income rises far enough, the room shrinks. Once your total taxable income for the year, meaning salary, dividends or trading profits, moves beyond £200,000, and your income including pension contributions exceeds £260,000, the £60,000 allowance begins to taper down.

For every £2 of adjusted income above £260,000, your allowance falls by £1. It continues shrinking until it reaches a minimum of £10,000.

A year of exceptional profit can therefore leave you with far less space than you expected, precisely when you are most inclined to make use of it.

So if your adjusted income is £300,000, that's £40,000 above the £260,000 level. Half of that, £20,000, is stripped from your £60,000 allowance. You're left with £40,000 of pension headroom instead.

Carry forward softens the blow. Unused allowance from the previous three tax years can be brought into the current year, provided you were a member of a pension scheme at the time. You use this year first, then work backwards. 

There's also the Money Purchase Annual Allowance. If you've already started drawing flexibly from a defined contribution pension, your allowance for new contributions is generally £10,000.

Using a SIPP to buy commercial property

Now we come to the part that causes directors to sit up slightly straighter.

Yes, a SIPP can buy commercial property. Offices, warehouses, workshops, bits of land. The sort of premises from which actual businesses operate. For certain owners, particularly those tired of paying rent to someone else, this is where the idea becomes rather attractive.

What it cannot buy, at least not without inviting swift and expensive displeasure from the authorities, is residential property. Flats, houses, holiday cottages, anything that smells faintly of personal enjoyment. There are a few narrow technical exceptions buried in the rulebook, but for practical purposes putting residential property inside a pension is likely to trigger punitive tax charges.

Commercial property, however, is fair game.

The pension can purchase the building, and your company can rent it from the pension. The rent your company pays is normally a deductible business expense. The rent the pension receives is generally free of income tax inside the scheme. When the property is eventually sold, any gain usually escapes capital gains tax within the pension wrapper. 

There is one condition, and it is not negotiable.

Everything must be done at market value with proper paperwork. In other words, if you decide to charge yourself a token rent because it feels convenient, or shuffle the price around to be helpful to one side or the other, the tax authority will take a dim view and may reclassify the difference as an unauthorised payment.

Borrowing is permitted, though not without limits. A registered pension scheme can generally borrow up to 50% of the net value of the fund at the time of borrowing. In practice, that means the SIPP can use a mortgage to help acquire the property, provided the numbers stack up and the lender is willing.

And then there are the costs: Stamp Duty Land Tax applies in the usual way; VAT may apply depending on the property and whether it has been opted to tax; legal fees, valuation fees, surveys, ongoing management.

A pension owning property is still, at heart, a landlord.

Done properly, holding commercial property inside a SIPP can align the business and the retirement plan rather elegantly. Done recklessly, it becomes an expensive education in why the rules were written so carefully in the first place.

Bottom line 

A properly structured pension contribution can feel a little like the scene in Genesis when Abraham prepares to sacrifice Isaac. The knife is raised and the loss appears grimly unavoidable. Then, at the last moment, a ram appears in the thicket and takes Isaac’s place on the altar.

The sacrifice still happens. Something is still given up. But the outcome turns out rather better than it first appeared.

A SIPP, used properly, is often how that ram shows up in the tax system.

Over the course of this article we have walked through why: company contributions that soften corporation tax, dividend rules that make employer funding attractive, annual allowances that matter in good years, taper rules that narrow the space at higher incomes, and even the possibility of holding commercial property inside the pension if everything is done at market value.
