PSA Automation Software

The ARKK Automation Platform automates PSA (PAYE Settlement Agreement) compliance for employers, pulling employee benefit and expense data from any source and calculating the tax and Class 1B National Insurance owed. Built-in machine learning checks every calculation for consistency, producing a submission-ready HMRC return with a full audit trail.

Employers still relying on manual spreadsheets for PSA face avoidable risk. Manual processes are prone to error, slow to scale across large employee populations, and leave businesses exposed to missed deadlines, since PSA returns are usually due by 5th July, with payment due by 22nd October.

+ What is PSA?

A PSA (PAYE Settlement Agreement) is a voluntary agreement with HMRC that allows employers to make one annual payment covering the tax and Class 1B National Insurance owed on minor, irregular, or impracticable employee benefits and expenses. Items included in a PSA do not need to be reported through payroll or on individual employee P11D forms. A PSA automation platform supports this process by bringing benefit data, calculations, and governance together in one environment.

+ How does ARKK automate PSA compliance?

ARKK automates PSA calculations by importing employee benefit and expense data from multiple source systems, applying configurable calculation rules, and producing a consistent, submission-ready return. Automated workflows reduce manual data handling, improve calculation consistency, and create an auditable record of results and adjustments.

+ How long does it take to implement a PSA solution?

Implementation time depends on factors such as the number of entities, source systems, data quality, and the range of benefit categories in scope. Most projects begin with data integration and process configuration before user testing and deployment. The ARKK Automation Platform is designed to be modular, meaning you can implement what you need and be operational in weeks.

+ Does ARKK integrate with existing ERP and data systems?

Yes. The ARKK Automation Platform is source-agnostic, meaning it connects to data from any system, whether that is an ERP, expense management tool, or spreadsheet-based process. Data is ingested once and reused across multiple reporting processes without limits on volume or complexity, removing the need to re-extract or reformat data for different compliance obligations.

+ How is data secured on the ARKK platform?

ARKK software is ISO 27001 certified, the internationally recognised standard for information security management. The Platform includes customisable workflows, defined team roles, and built-in validations, ensuring that access controls and data integrity are maintained throughout the PSA lifecycle.

+ What are risks of managing PSA manually?

Manual PSA processes increase the risk of miscategorised benefits, inconsistent tax and National Insurance calculations, limited auditability, and missed deadlines. As employee numbers and benefit categories grow, spreadsheet-based processes become harder to govern and maintain. Automating data collection and calculations helps reduce these risks while improving consistency ahead of the 5 July and 22 October deadlines.
