SIPP and SSAS Differences

This site is principally aimed at those associated with SIPP and SSAS. Whilst in the main the two are similar there are some subtle differences between the two. Some of the main ones are summarised below:

Aspect Self Invested Personal Pension Small Self Administered Scheme
Structure An individual based arrangement, often (but not always) created by a 'master-trust' that creates the SIPP - individual scheme members' 'arrangements' being Sub-trusts of the mastertrust. As such this is a personal pension arrangement. A scheme that can accommodate up to eleven members. This too is a trust-based scheme, in most cases, created at the request of an employer for directors and/or key personnel (although it does not have to be an employer). As such this is an occupational pension arrangement.
Trustees In all cases there will be a 'professional' trustee, unless set up under Deed Poll, being either the scheme operator or a separate trustee company. Depending on how the scheme is set up, the individual SIPP member may also be a trustee of their SIPP.  It is usual for all members to also be scheme trustees. Whilst not a requirement, in most cases 'professional' administrators and/or trustees can be appointed to assist the member trustees in the running of the scheme.
Investment - Loans A SIPP cannot make a loan to a 'connected party' without incurring a tax charge. A SSAS can make a loan to a 'sponsoring employer' subject to stringent conditions regarding the loan term, amount, repayments, interest rates and security.
Investment - Shares A SIPP may invest in shares of a company even if it is connected to the scheme member (although there may be tax implications if 20% or more of the share capital is held by the member and member's connected persons, including SIPP interests). A SSAS is restricted to investing no more than 5% of the scheme assets in the shares of any one sponsoring employer (although there may be tax implications if 20% or more of the share capital is held by the member and member's connected persons, including SSAS interests).
Regulation The marketing and running of a SIPP is covered by the Financial Conduct Authority. A SIPP is also subject to an element of regulation by The Pensions Regulator. A SSAS is subject to regulation by The Pensions Regulator.
Complaints Can be made to the Financial Ombudsman Service in relation to the sale of a SIPP, fees, pension administration or any other matter relating to the SIPP or the Pension Ombudsman where it relates to pension administration. Can be made to the Pension Ombudsman in relation to pension administration.
Compensation Failure of the SIPP operator is covered by the Financial Services Compensation Scheme.  None on failure of SSAS operator or trustee.
Investments Specific investments or shares thereof held for each member  Investments held for all members with each member having a notional interest in the investments.
