Your PSA.
Intelligent.
An AI-assisted categorisation and reporting platform built to speed up the PAYE Settlement Agreement reporting process.
PSA.I ingests expenses data, classifies it against a controlled PSA framework, and produces a reviewable, defensible PSA calculation. For one PSA or an entire portfolio.
Reduce manual review
Focus attention on the rows that actually need judgement.
Keep reviewer control
AI suggests. Reviewers confirm, override or reassign.
A defensible outcome
Every step from upload to result is visible and auditable.
Purpose-built PSA categorisation and reporting
PSA preparation is often slow, manual and time-sensitive. Expense files arrive in different formats, descriptions are inconsistent, and the tax treatment still requires judgement. PSA.I standardises the workflow — from raw data to a defensible PSA result.
Flexible data ingestion
Upload spreadsheet-based data from finance, payroll, expense or general ledger sources. Column mapping supports client-specific file layouts.
AI classification with confidence
Each row receives a suggested PSA category and a confidence score, helping reviewers prioritise exceptions and edge cases first.
Reviewer-in-the-loop workflow
Categories can be confirmed, overridden or reassigned. The platform supports professional judgement rather than replacing it.
Data quality checks before review
Normalisation, duplicate detection and error handling clean the data up front, so reviewer time isn't wasted on avoidable noise.
HMRC-aligned reporting output
Once review is complete, PSA.I produces a grossed-up PSA calculation, including Class 1B NIC, ready for review and reporting.
| Benefit type | Cost of benefit | Grossed-up tax | Class 1B NIC | Total due |
|---|---|---|---|---|
| Business travel | 382.97 | 95.74 | 66.06 | 161.80 |
| Client entertaining | 201.35 | 50.34 | 34.73 | 85.07 |
| Staff entertaining | 1,248.50 | 312.13 | 215.37 | 527.50 |
| Staff welfare | 456.20 | 114.05 | 78.69 | 192.74 |
| Total | 2,289.02 | 572.26 | 394.85 | 967.11 |
For one PSA or a whole portfolio
PSA.I supports both in-house PSA preparation and multi-client delivery. A single employer can use it to manage one annual PSA end to end. A professional services team can use it to run multiple PSAs in parallel, each with its own data, category mappings, reviewer history and results.
Own one PSA, end-to-end
Replace the spreadsheet cycle. Bring expenses data in from finance, HR and expense systems in whatever shape it arrives. Let AI handle the first-pass classification, then review the rows that actually need judgement.
- Standardised workflow across cycles
- Reviewer time goes to the rows that need it
- Confirmed decisions retained for next year
- Audit-ready trail for internal governance and HMRC enquiry readiness
Run a portfolio in parallel
Each engagement runs in isolation, with its own data, category library and learning history. Confirmed patterns for one client do not bleed into another. Dashboarding monitors progress across the book.
- Per-engagement isolation by design
- Portfolio dashboards for progress and risk
- Client-specific category mappings preserved
- Consistent reviewer workflow across engagements
Designed for the work, not around it
PSA.I is built specifically for PSA categorisation and reporting — not adapted from a general classifier or a general document tool.
Purpose-built for PSA
Designed around PSA workflow, categorisation and reporting, with dashboarding features to monitor progress.
Per-engagement isolation
Each PSA has its own data, category library and learning history. Confirmed patterns for one engagement do not bleed into another.
Defensible audit trail
Every upload, suggestion, override and final categorisation is recorded, supporting internal governance and HMRC enquiry readiness.
Human judgement built in
The platform is designed to accelerate review, not bypass it. Reviewers remain in control of every final categorisation.
Learns over time
Confirmed reviewer decisions improve future suggestions within each engagement, making the process more efficient as work progresses.
HMRC-aligned output
Produces a grossed-up PSA calculation by benefit type, including Class 1B NIC, ready for reporting.

PAYE Settlement Agreements: getting the data right for 2025/26
Why the rules look simple but rarely are — and why the data side, not the rules, is where most in-house PSA cycles actually go wrong. A look at the £150 annual function exemption trap, supplier-coding drift across the year, and what it takes to keep the classification step defensible.
