Getting Started with a SSAS

Decide who will be a part of the scheme.
You can have up to 11 members. All members must be 18 or older.
You can invite directors of the company, other employees, family members, and employees' family members.

7 steps to establish your SSAS

Step 1: Information about Your Company and the Members of the SSAS

To set up a SSAS, you will need to gather information about your company and each member of the SSAS. Each member will need to provide you with their personal details (contact information, etc.) and a signature. You will also need to decide on a name for your scheme.

In addition to collecting basic details, you will need to know if any members of the pension hold a certificate of protection or a HMRC protection reference number, as well as check if the Money Purchase Annual Allowance applies to any members of your scheme.

Book an enquiry with one of our pension advisers for a full list of the documentation you will need to open a SSAS.

Step 2: Anti-Money Laundering

Complying with anti-money laundering legislation is a legal requirement. It is important that each member of the SSAS has their identity verified.

Step 3: Transfer Existing Pensions

Every member of the SSAS must decide whether they would like to transfer any existing pensions to the new scheme. This is optional and each member may transfer as many or as few pensions as they like. We recommend that each member of a new SSAS talks to an independent financial advisor before making a decision.

Step 4: Trust Documentation

A SSAS is a trust, which means that it is run by designated trustees. All members of the SSAS are trustees, although a member can opt out in very specific circumstances. The SSAS needs at least 1 trustee to continue.

The pension must also include a pension administrator. The SSAS scheme administrator can be a member or trustee or an appointed professional. Being a trustee comes with legal responsibilities, so all trustees should know their obligations and the potential consequences of failing to meet those obligations.

We also recommend that any SSAS service you employ includes legal compliance of the package. This can help protect the scheme from breaching HMRC rules and The Pension Regulator's regulations.

Step 5: Registering with HMRC

The trust needs to be registered with HMRC before any contributions are received. The trust will also need to open a bank account to receive contributions.

Step 6: Obtain a Pension Scheme Tax Reference Number

A Pension Scheme Tax Reference (PSTR) number is a unique code made up of eight numbers, followed by two letters (XXXX XXXX OO). Every new SSAS will need a PSTR from HMRC, as it shows that the scheme has been registered for tax relief and exemptions.

Step 7: Register the SSAS with the Pensions Regulator

The Pensions Regulator is the UK Regulator for work-based pensions, which includes SSAS. It is important to register your SSAS with the Pensions Regulator. The Pensions Regulator is sponsored by the Department of Work and Pensions (DWP).

Setting up a SSAS — common questions

How long does it take to set up a SSAS?

HMRC registration typically takes eight to sixteen weeks, depending on HMRC's current workload. The application itself is straightforward — TLPI prepare the HMRC registration pack and submit it on your behalf. You can expect to receive your SSAS reference number and be able to begin investing within two to four months of starting the process.

Do I need a professional administrator for my SSAS?

You are not legally required to appoint a professional administrator, but TLPI strongly recommend it. The Pensions Regulator and HMRC hold all scheme trustees personally responsible for compliance. A professional administrator manages scheme accounts, annual returns, HMRC correspondence, and investment documentation — removing the compliance burden from the director-trustees.

Can I transfer existing pensions into my new SSAS?

Yes. Existing personal pensions, workplace pensions, and frozen pension pots can all be transferred into a SSAS. TLPI manage the transfer process, including requesting valuations from existing providers and liaising with HMRC. Consolidating into one SSAS increases the total fund available for investment and can reduce the overall charge burden.

Can my SSAS have more than one member?

A SSAS can have up to 11 members, all of whom must be connected to the sponsoring employer (typically as directors or senior employees). Each member becomes a trustee of the scheme. Adding family members — including a spouse — is common, provided they meet the sponsoring employer connection requirement.
