Country Regulations.
Payroll compliance for 11 countries.

A country regulation is a self-contained compliance package that runs on the Payroll Engine platform. It encodes the statutory rules for a country — income tax calculation, social security contributions, local levies, employer costs, and statutory reporting — as structured, testable logic. You deploy a regulation alongside the open-source runtime and get a fully compliant payroll engine for that country, without building the rules yourself.

Each regulation covers the full statutory scope and is updated annually to reflect changes in tax law, contribution rates, and reporting requirements.

Annual compliance updates

Tax tables, rate changes, ceiling adjustments, and new statutory rules are published each calendar year — versioned and independently deployable.

Integration test suite

Every regulation ships with a full set of integration tests. Tax and social security results are verified against official examples and edge cases.

No-Code / Low-Code authoring

WageType logic uses the Payroll Engine action system — no C# code required for standard cases. Company-specific overrides layer on top cleanly.

Retro correction support

All regulations are built retro-capable. Period re-runs, delta calculations, and cascading corrections are handled by the Payroll Engine runtime.

Exchange JSON deployment

Regulations are deployed as Exchange JSON packages via the pecmd CLI or REST API. No build step, no server restart.

Open-source runtime

Regulations run on the MIT-licensed Payroll Engine platform. The calculation engine, API, and toolchain are fully auditable.

What Payroll Engine provides

Full country regulations incl. data regulations

Each country ships as a complete regulation set: the core calculation regulation plus versioned data regulations (tax tables, SV ceilings, contribution rates). All statutory rules — income tax, social security, and local contributions — are implemented as executable, test-driven logic verifiable against official examples.

Updates — annual & intra-year

Regulations are updated on two cycles. Annual updates align with each new tax year: new PAP, rate changes, ceiling adjustments. Intra-year updates cover statutory changes during the year — quarterly adjustments, revised thresholds, emergency legislation, or corrected official parameters — released as patch data regulations independently of the core.

Customer responsibility

Software certification

Some countries require the payroll software itself to be certified by a statutory body before it can be used for official submissions. Obtaining or operating under a certified integration is the deploying entity's responsibility. Country-specific certification requirements are listed on each country regulation page.

Filing & data registrations

All countries require employer registrations with tax and social security authorities and access to the relevant electronic filing systems. The specific systems, certifications, and registrations vary by country and are the sole responsibility of the deploying entity. Details are listed on each country regulation page.

Note: Payroll Engine regulations produce payroll results and statutory reports (XML/JSON). The transmission of these reports to tax authorities, social security institutions, or other statutory bodies requires separate certifications that are the sole responsibility of the deploying party.
