The short version
- Employer contributions avoid both National Insurance charges.
- Contributions are normally an allowable business expense.
- A SSAS can lend back to the sponsoring employer, within strict rules.
- Unused allowance from earlier years can sometimes be carried forward.
Directors of small limited companies spend a good deal of time on the salary-and-dividend question and comparatively little on the third route. Yet for many, an employer pension contribution is the most tax-efficient way to move profit out of the company — particularly since dividend taxation became less generous.
Why employer contributions work so well
A contribution paid by the company directly into your pension sits outside the payroll taxes entirely. There is no employee National Insurance and no employer National Insurance on it. Provided it meets the “wholly and exclusively” test for business purposes, it is normally deductible against corporation tax.
Compare that with the alternatives. Salary carries income tax and both classes of National Insurance. Dividends are paid out of post-corporation-tax profit and then taxed again in your hands. The pension route avoids a good deal of that — the trade-off being that the money is locked away until the normal minimum pension age.
The allowances that constrain it
The main limit is the annual allowance, which covers all contributions from all sources in a tax year, including employer contributions and any auto-enrolment. Exceeding it creates a tax charge that removes the benefit.
- The allowance is reduced for very high earners through tapering.
- It is reduced sharply once you have flexibly accessed a defined contribution pension.
- Unused allowance from the three previous tax years can often be carried forward, provided you were a member of a registered pension scheme in those years.
Carry forward is the feature most often missed. A company that has had a strong year can sometimes make a contribution several times the standard annual allowance by using unused capacity from earlier years — subject to the detail, which needs checking properly rather than assumed.
SIPP or SSAS?
Most directors are well served by a self-invested personal pension. It is a personal arrangement, widely available, comparatively cheap, and offers a broad investment range including commercial property. For the large majority, that is the right answer.
A small self-administered scheme is a different animal. It is an occupational scheme, usually set up by the company for a handful of directors, with the members typically acting as trustees. It is more complex and more expensive to run, and it earns that cost only where specific features are needed.
- Loanback. A SSAS can lend money to the sponsoring employer, subject to strict conditions on security, interest, term and the proportion of the fund. A SIPP cannot.
- Pooled assets. Several members can hold an asset such as trading premises jointly within one scheme.
- Shared control. Members as trustees have direct control over investment decisions.
- Family succession. A SSAS can accommodate family members across generations.
Holding your trading premises
One of the more compelling uses is for the pension to buy the commercial property the business trades from. The company pays market rent to the pension, which is an allowable business expense. The rent lands in a tax-privileged environment, and growth in the property value occurs inside the pension rather than on the company balance sheet.
It also separates a valuable asset from trading risk, which matters if the business later encounters difficulty. The arrangement must be done properly — an independent valuation, a formal lease, rent actually paid at a commercial rate — because HMRC treats these as connected-party transactions and looks closely at them.
Timing around the company year end
Corporation tax relief on an employer contribution is normally given in the accounting period in which the contribution is actually paid, not the period in which it is declared or intended. A contribution paid a week after the year end generally relieves against the following year.
For a company with an unusually profitable year, that timing difference can be worth a great deal. It is one of the few genuinely time-sensitive items in the whole area, and it is worth raising with your accountant well before the year end rather than in the week after it.
Where it goes wrong
- Contributions large enough relative to the director’s role that HMRC challenges the “wholly and exclusively” test.
- Exceeding the annual allowance because auto-enrolment contributions elsewhere were forgotten.
- Assuming carry forward is available without checking scheme membership in the earlier years.
- Setting up a SSAS for its own sake, then paying for complexity that is never used.
- Property transactions run informally between connected parties, without a proper lease or valuation.
