Who is affected, by how much, and what should we communicate?
Employee: compare the same pension sacrifice under current NI treatment and the announced 2029 treatment.
Reward and finance: estimate employee NI, employer NI and cost by representative salary band. Averages cannot establish actual affected headcount.
Communications: give employees a private self-service answer, then measure completion and self-reported understanding without collecting their figures.
Salary and contribution first. Payroll detail stays optional.
Bonus exchange is available when relevant. Tax region, code, NI category, loans, payroll frequency and minimum-wage assumptions remain inside advanced settings.
Model the change without employee data.
Use salary-band averages and headcounts. No names or payroll IDs. Use representative groups, not identifiable employee records.
Tax region for these configured examples: Scotland. Split mixed-region work into separately configured comparisons.
Download before leaving to retain your work. Files stay on your device; no account or upload is required. Keep labels non-identifying. Reopening requires the same model and policy version.

What is and is not included
Announced 2029 treatment: the first £2,000 of annual pension salary sacrifice is modelled as NI-exempt and the excess as employee and employer NI-able. The annual exemption is allocated proportionally for planning.
Included: contractual salary, configured employer pension funding, shared employer NI saving and estimated employer Class 1 NI using 2026/27 rates.
Excluded: Employment Allowance, Apprenticeship Levy, directors’ annual methods, irregular payroll, benefit changes, opt-out behaviour, implementation fees and employee-level payroll validation.
A report you can review and reuse.
The editable model exports a CSV, an editable report and a printable planning report. A separately scoped employee campaign adds approved configuration, branded employee delivery, acceptance testing and a close-out report using aggregate, value-free engagement evidence.
- Decision evidence
- Representative-band estimates of employee NI, employer NI and annual cost
- Communication evidence
- Started, completed, self-reported confidence and next-step counts
- Governance evidence
- Calculation contract, official sources, assumptions and exclusions
Useful now, honest about what is not final.
This is an annual planning model of announced policy using 2026/27 rates. Final 2029 rates, payroll reporting and pay-period allocation remain subject to legislation and HMRC guidance. It is not payroll advice or an employee-level payroll acceptance test.
Launch one governed 2029 planning campaign.
One employer, one approved configuration and one 30-45 day campaign, including the employee journey, anonymous workforce model, implementation support and evidence report.
