Payetools

Cross-platform Open-Source Library for UK payroll

Payetools is the first library of its kind to bring open-source capabilities to UK payroll processing via a robust, cross-platform framework written in C#.

Payetools contains support for calculating the following:

• UK Income Tax (all jurisdictions)
• National Insurance
• Student Loans
• Pensions using Qualifying Earnings and Pensionable Pay earnings bases (under both Relief at Source and Net Pay Arrangement tax treatments)
• Compliance with National Minimum/Living Wage regulations

See the Program.cs of the example project for step-by-step instructions on getting your first pay run output.

The code passes HMRC tests for income tax, National Insurance, student loans and National Minimum Wage.

Tests are included for 2022-2023 and 2023-2024 tax year rates and thresholds. 2024-2025 testing is due shortly.

Separately, Payetools is currently working on libraries for HMRC RTI and DPS services that sit on top of the core Payetools open-source libraries published here. The Payetools.Hmrc libraries enable the publishing of FPS and EPS submissions to HMRC and the retrieval of notifications (e.g., tax code changes, student loan starts/stops, etc.) from HMRC's Data Provisioning Service (DPS). Payetools.Hmrc will be available as a commercial offering - please contact info [at] payetools.com for further information.

Releases

Releases are made via nuget - search for payetools to see all libraries for this repo or follow this link. Packages are built with compatibility with .NET 6.0, 7.0 and 8.0.

Reference Data

Payetools relies on static reference data to drive tax, NI, etc., calculations (the machine-readable equivalent of HMRC's Rates and thresholds for employers page. There is currently no high availability source of this data, but a version for testing can be found at https://uk-rates-and-thresholds-data.netlify.app/index.json. (2022-2023, 2023-2024 and 2024-2025 reference data sets are currently published.)

Documentation

Limited API documentation is available at https://payetools.dev/api/Payetools.html. This is very much a work in progress.

Roadmap

To follow.
