Once you understand that an employer pension contribution is the most tax-efficient way to extract profit from a PSC, a practical question follows immediately: which pension scheme should the money go into? The tax treatment is the same for any registered scheme, but the vehicle you choose affects investment control, charges over decades of accumulation, and the protections that apply if something goes wrong. This page sets out the main options at a level a contractor can use when preparing to take regulated financial advice.

One boundary must be stated plainly at the outset. We are accountants, not regulated financial advisers. Confirming the tax structure of a contribution is accounting work. Choosing a pension scheme, selecting investments, recommending a provider, or advising on transferring existing pensions are regulated financial advice activities that require authorisation from the Financial Conduct Authority. A contractor who wants a scheme recommendation needs to speak to an FCA-authorised independent financial adviser. This page gives the context to make that conversation more productive, not a substitute for it.

The three main pension types open to contractors

Most contractors operating through a PSC will encounter three main categories of pension vehicle. They differ in structure, investment flexibility and administration, but not in the fundamental tax treatment of contributions.

Personal pensions

A personal pension is a contract between an individual and a pension provider. The individual (or their employer) pays contributions in, the provider invests them according to the options available within the scheme, and the pot grows until retirement. Modern personal pensions from major providers are straightforward to open, accept employer contributions, and typically offer a range of managed or passive funds. They suit contractors who prefer a guided, lower-involvement approach to investment selection.

The investment menu is usually more limited than a SIPP, which suits many contractors perfectly well. If the fund range meets your needs, a well-structured personal pension with competitive charges can be entirely suitable. The employer contribution mechanics are the same: the company pays directly to the provider, the deduction is taken against corporation tax, and the money is not taxable on the director as income on the way in.

SIPPs (Self-Invested Personal Pensions)

A SIPP is a type of personal pension with a wider investment mandate. The same tax rules apply, but the holder can invest across a broader range of assets: individual stocks and shares, exchange-traded funds, investment trusts, bonds, commercial property (in a full SIPP) and many other instruments, depending on the provider's platform.

In practice, SIPPs sit on a spectrum. A platform-based or "lite" SIPP from a major investment platform typically offers access to a wide fund range and listed equities with a straightforward charging structure, usually an annual platform fee plus fund charges. These are the most common choice for contractors who want investment flexibility without the complexity of a full SIPP. A full SIPP offers a still-broader asset range, including direct commercial property ownership, but carries higher administration costs and is generally suited to larger pots where the wider investment options justify the overhead.

SIPPs became the standard contractor choice for several reasons. They accept employer contributions directly, they give the director control over investment allocation, and the platform technology makes them easy to manage alongside a PSC director's other financial accounts. They are also portable: if you move between providers or wind down the company, the SIPP stays with you personally and contributions can be paused without closing the scheme.

Workplace pension schemes

A workplace pension is an occupational arrangement set up through a provider for a company's workforce. For a sole-director PSC, a workplace scheme is essentially the director acting simultaneously as employer and employee, setting up a group scheme through a specialist provider. Some providers offer workplace schemes specifically designed for small companies and sole directors, which can accept employer contributions in the same way as a SIPP.

The practical difference from a SIPP is usually investment choice and the default structure: workplace schemes often have a default fund and simpler contribution-setting mechanics, while SIPPs give the holder more direct control over allocation. There is no tax difference. Some contractors prefer the simplicity of a workplace-style structure; others prefer the investment flexibility of a SIPP. Both are valid, and the right choice depends on your investment preferences and the cost comparison between specific providers.

Why PSC directors often use SIPPs

The pattern of a contractor using a SIPP as the primary pension vehicle is common enough to be worth explaining, because the reasons are practical rather than inherent to the SIPP structure.

First, investment control. A sole-director PSC is in many ways a professional investor in their own labour and business skills. Many contractors want the same level of autonomy in their pension investments as they apply to other financial decisions. A SIPP, particularly a platform-based one, lets the holder build a portfolio across asset classes without being restricted to a provider's default fund.

Second, compatibility with the employer contribution structure. Most modern SIPPs are explicitly set up to accept employer contributions and the process is well-documented by providers. A contractor accountant and a pension provider can confirm the correct payment method, and the contribution flows directly from the company's bank account to the scheme.

Third, portability and continuity. A SIPP is a personal arrangement that stays with the individual regardless of what happens to the company. When the PSC is wound down, when the contractor moves between companies, or when contracting activity changes, the SIPP continues. Contributions can be scaled up, scaled down or paused without touching the scheme structure.

Fourth, consolidation capability. Many contractors accumulate pension pots from previous employment before they began contracting. A SIPP can, subject to advice on whether transfer is appropriate in each case, act as a consolidation vehicle for those older pots, simplifying the overall picture. Whether any specific transfer makes sense is a regulated advice question (see the consolidation note below).

None of this means a SIPP is the right choice for every contractor. It means the SIPP structure tends to fit the way PSC directors work. A contractor who has no strong preference for investment selection and wants a simpler structure may find a modern personal pension or workplace scheme equally effective at lower or comparable cost.

What the employer contribution route looks like in practice

Understanding the mechanics helps when dealing with both a pension provider and an accountant. The employer pension contribution process for a PSC director works as follows.

The company, acting as employer, makes a payment from its bank account to the pension provider. The payment is labelled as an employer contribution on the provider's records. The amount must sit within the director's available annual allowance for the tax year (currently £60,000 for 2026/27, with carry-forward available from the previous three tax years if not fully used). The contribution is deducted from the company's profits before corporation tax is calculated, on a paid basis under Finance Act 2004 s.196, subject to the wholly-and-exclusively test. No employer or employee National Insurance applies. The director does not pay income tax on the contribution in the year it is paid in.

This is the same regardless of whether the scheme is a SIPP, a personal pension or a workplace scheme. The tax outcome is set by Finance Act 2004, not by the scheme type. What the scheme type affects is what happens inside the scheme: which assets can be held, what the charges are, and who controls the investment decisions.

The annual allowance and carry-forward mechanics are covered in detail in the dedicated guides to employer pension contributions for PSC directors and pension carry-forward for contractors. This page does not repeat that ground; the point here is that all of it applies regardless of scheme type.

What to weigh when comparing schemes

While scheme selection is a regulated advice question, understanding the factors at play helps a contractor prepare for that advice conversation. The following are the main dimensions to consider.

Charging structure and total cost

Charges compound over an accumulation period in the same way investment returns do, but in the opposite direction. A scheme costing 0.5% per year more than an equivalent alternative will produce a materially smaller pot over a twenty-year career, all else being equal. The total cost of ownership is what matters: the platform or administration fee, the charges on the underlying funds, any dealing costs, and any one-off fees for specific transactions.

On platform-based SIPPs and personal pensions, a common structure is an annual platform fee (sometimes a flat amount, sometimes a percentage of the fund value) plus the ongoing charges figure of the funds held. Comparing providers on total cost at your expected pot size and fund mix gives a more useful picture than comparing headline platform fees alone.

Different charging structures suit different pot sizes. A percentage-based platform fee favours smaller pots; a flat annual fee favours larger ones. At a higher pot value, even a small reduction in the ongoing percentage fee translates to a significant cash difference each year. This is part of the regulated advice consideration, but it is worth understanding the mechanics before entering that conversation.

Investment flexibility

If you want to hold a wide range of assets, including individual equities, specialist funds or commercial property, a SIPP is the natural vehicle. If a diversified passive or multi-asset fund within a personal pension or workplace scheme meets your needs, the wider flexibility of a SIPP may not justify any additional cost or complexity it carries.

Investment selection is a regulated activity. The choice of which assets to hold within a scheme, and how to allocate across them, is advice that must come from an FCA-authorised adviser or be a genuinely informed, unadvised decision by the individual. What the accountant can confirm is that the scheme structure is compatible with employer contributions and that the tax mechanics are correct.

FSCS protection

The Financial Services Compensation Scheme provides protection if an FCA-authorised firm fails and you suffer a loss as a result. For pension assets, the applicable protection depends on the type of scheme, the nature of the failure and the FSCS rules in force at the time. Pensions are not protected in the same way as cash deposits; the cover is conditional and technical.

For a platform-based SIPP or personal pension, the assets within the scheme are typically held in a nominee or trust structure separate from the provider's own balance sheet, which means a provider insolvency does not automatically mean the assets are lost. The protection picture for any remaining exposure (for example, uninvested cash held by the provider, or assets that cannot be transferred quickly) sits within the FSCS framework but with rules specific to investment and pension providers rather than deposit-takers.

Understanding the protection that applies to a specific scheme is a reasonable part of due diligence, and the provider should be able to explain it. An FCA-authorised adviser can also set out the protection framework in the context of a specific recommendation. This page states the topic exists and matters; it does not specify limits that depend on the specific scheme structure and rules that can change.

Provider stability and operational quality

The pension will likely run for several decades. The operational quality of the provider, its track record, its platform reliability and its process for handling contributions, transfers and retirement access are all relevant, even though they do not carry a single numerical measure in the way charges do. A provider with a simpler charging structure but a poor record of administration errors or slow transfer handling may cost more in practice than one with a slightly higher fee and a better operational reputation.

This is again part of the regulated advice conversation, but it is worth raising as a question when speaking with a financial adviser: what is their experience of the provider's actual service, not just its fee schedule.

A note on SIPPs that accept commercial property

Full SIPPs can hold commercial property, including a contractor's own business premises if the company occupies them. This is a specialist area with its own rules, HMRC requirements and risks, and it is mentioned here only to flag that it exists and is distinct from the investment flexibility of a standard platform-based SIPP.

Purchasing commercial property within a pension involves the scheme acquiring a real asset, the company potentially paying a market-rate rent to the scheme, and the property being subject to pension rules on use and disposal. It requires specialist legal, SIPP administration and financial advice. A contractor who is interested in this structure should speak to a regulated financial adviser and a specialist SIPP administrator before taking any steps.

The consolidation question

Many contractors arrive at PSC contracting with pension pots from previous employed positions. The question of whether to consolidate those pots into a SIPP is a regulated advice question, not an accounting one, but the context is worth understanding.

Consolidating defined-contribution pots from previous employment into a SIPP can simplify administration, potentially reduce overall charges and make it easier to see the whole pension picture in one place. Whether it makes sense depends on the charges and features of the existing pots, any exit fees, and whether the receiving SIPP offers genuinely better value or functionality.

Defined-benefit (final salary) pension rights are different. Transferring out of a defined-benefit scheme means exchanging a guaranteed income in retirement for a pot of money, which is a significant and usually irreversible decision. For pots worth more than £30,000, a transfer away from a defined-benefit scheme legally requires advice from an FCA-authorised pension transfer specialist before it can proceed. In many cases the advice will be not to transfer, because the guaranteed income is valuable.

Some older defined-contribution schemes carry valuable features such as guaranteed annuity rates that can be worth more than the flexibility gained by transferring. Again, the assessment of whether to stay or move is advice for a regulated adviser.

The SSAS: when it comes up and what it is

A SSAS (Small Self-Administered Scheme) is an occupational pension scheme, trust-based and connected to the sponsoring employer, typically used by small companies with a handful of members including directors and family. It differs from a SIPP primarily in that it is a company scheme rather than a personal arrangement, and it can carry out certain transactions (lending to the sponsoring company, for example, subject to strict rules) that a SIPP cannot.

SSASs come up occasionally in contractor circles, usually in the context of family-member directors, multiple shareholder-directors, or the ability to lend back to the company. They are more complex to administer than a SIPP and involve their own regulatory requirements. For a sole director they are rarely the simpler or more cost-effective option. If a SSAS is relevant to your situation, a specialist financial adviser and pension administrator should be involved from the outset.

Where accounting ends and financial advice begins

This boundary is worth stating with precision, not just as a disclaimer but because contractors sometimes assume their accountant can cover both.

What a contractor accountant handles:

  • Confirming the contribution is structured as an employer contribution (paid by the company, to the provider, not via the director's personal account).
  • Confirming the scheme is a registered pension scheme for the purposes of Finance Act 2004.
  • Calculating whether the contribution is within the annual allowance, including carry-forward and any taper interaction, based on the figures available.
  • Ensuring the corporation tax deduction is taken in the right accounting period (paid basis).
  • Making sure the wholly-and-exclusively test is satisfied in the company's circumstances.
  • Confirming the Self Assessment or payroll reporting is correct.

What requires an FCA-authorised independent financial adviser:

  • Recommending a specific pension scheme or provider.
  • Advising on the investment allocation within a scheme.
  • Advising on whether to transfer existing pension pots.
  • Advising on pension access strategy at retirement (drawdown versus annuity and so on).
  • Assessing whether the overall pension structure suits your financial position and retirement goals.

The two roles are complementary and both are genuinely useful. A contractor who has their employer contribution structured correctly for tax but is in a scheme with high charges and unsuitable investments is losing value. One who has chosen a well-structured scheme but has not set up the employer contribution correctly is losing the tax benefit. Getting both right, from the relevant professional in each case, is the complete picture.

If you are not currently working with an independent financial adviser on your pension, it is worth putting that in place alongside your accountant. The combination of employer contribution structuring (accounting) and scheme and investment selection (regulated advice) is where the full benefit of the pension lever is realised.

Practical steps before talking to an adviser

Having the right information to hand when you approach a financial adviser makes the conversation more efficient and the advice more accurate. The following are worth preparing before that meeting.

First, your current pension position. Gather annual statements from every scheme you hold, including old workplace pensions from previous employment. Know roughly how much is in each pot, whether any are defined benefit, and whether any have guarantees such as guaranteed annuity rates. A financial adviser will need this picture before recommending a consolidation strategy.

Second, your annual allowance position. Your accountant can confirm how much of the £60,000 annual allowance (2026/27) you have used, whether any carry-forward is available from the previous three years, and whether the taper or the money purchase annual allowance applies to your situation. Bringing a clear allowance figure to the adviser meeting removes one area of uncertainty.

Third, a sense of your objectives. Are you primarily building a retirement pot, planning for a company exit in a defined timeframe, or wanting to reduce a high-profit year's tax bill? The objective shapes the advice, and a clear brief leads to more targeted recommendations.

Fourth, your company's financial position. The contribution needs to be genuinely affordable and commercially justifiable. Your accountant will have this picture; sharing it with the financial adviser ensures the recommendation is grounded in what the company can actually fund without affecting working capital.

Getting the structure right

The scheme selection question is often the last piece of the employer pension contribution puzzle. Once you know the contribution makes tax sense (covered in our guide to contractor employer pension contributions), have confirmed the carry-forward position (covered in our pension carry-forward guide), and have structured the overall salary and dividend split (see our guide to PSC limited company contractor tax), the question of which scheme to use becomes a regulated advice conversation grounded in good accounting preparation.

We work with limited company contractors across sectors, from IT contractors to engineering and finance roles, to ensure the pension contribution is correctly structured for tax. If you would like to confirm your allowance position, the accounting treatment of a planned contribution, or simply understand what information to bring to a financial adviser, our contractor accountancy service can help. This article is general information for the 2026/27 tax year; it is not personal tax or financial advice, and the right scheme and investment choices for your circumstances require input from a regulated financial adviser authorised by the FCA.
