Why run a salary sacrifice audit?
Most EV salary sacrifice schemes launch well. The issues appear later, in the seams: joiners and leavers, payroll setup, documentation drift, insurance responsibilities, and employee communications that are accurate but incomplete.
An audit is a structured review of how your scheme works end-to-end. It is not a provider selection exercise; it is a practical health check you can run at any point to reduce employer risk and improve employee experience.
If you are still shaping your approach, start with salary sacrifice advisory. If you already operate a scheme, the checklist below is the fastest way to find high-impact fixes.
The audit checklist (10 areas)
Designed to be scannable; each point should translate into a clear action or an evidence request.
1) Governance and ownership
Named scheme owner (role, not person); clear responsibilities across HR, payroll, finance, fleet, and sustainability.
2) Eligibility and policy
Eligibility matches payroll reality; policy covers probation, leave, sickness, and exceptions.
3) Joiner and leaver journeys
Operationally workable leaver process, including early termination scenarios and cost recovery rules.
4) Employee communications
Plain-English comms that explain commitment, risk, and what happens when circumstances change.
5) Payroll setup
Deductions configured correctly; reconciled monthly; clear ownership for fixes when things break.
6) Tax and reporting
Treatment understood and evidenced; reporting responsibilities agreed and documented.
7) Insurance and risk allocation
Clear responsibilities across employer, employee, and suppliers; claims process is tested, not assumed.
8) Supplier controls
Commercial terms, service levels, escalation paths, and a practical continuous improvement rhythm.
9) Data and management information
MI covers uptake, drop-off, exceptions, leavers, and employee feedback; not just ‘cars on scheme’.
10) Economics and outcomes
Employer and employee value is evidenced; assumptions are kept current as pay and vehicle availability change.
The terms you should define clearly
If your scheme pack discusses taxable benefits, spell out key terms on first use, then use the acronym. For example:
- Benefit in kind (BIK)
- Optional Remuneration Arrangements (OpRA)
- P11D reporting (P11D)
- HMRC expectations and evidence
Useful next steps: employer savings tool, BIK calculator, and the glossary.
