How to Set Up Multi-Country Payroll

Overview

Plenix payroll is multi-country. Each payroll run resolves a country code (defaulting to GB) and applies that country's configured tax bands to calculate income tax and national insurance. You define these once per country and reuse them across every run.

Step 1 — Open Payroll Countries

1. Go to HCM → Payroll → Payroll Countries
2. You will see the countries already configured (the UK / GB ships by default)

Step 2 — Add or edit a country

1. Click + Add Country (or edit an existing one)
2. Set the country code (ISO, e.g. GB, IE, US)
3. Define the tax bands — each band has a threshold and a rate:
   • Income tax bands (e.g. personal allowance, basic, higher)
   • National insurance / social security bands
4. Save

Step 3 — Assign a country to employees or a run

• An employee's country is taken from their profile / branch, or
• A payroll run can specify the country code for the group being paid

When the run executes, Plenix loads the matching country config and applies its bands to each employee's gross pay.

Step 4 — Verify the calculation

1. Run a payroll (see How to Run Payroll with Payslips)
2. Open an employee's payslip
3. Confirm the income tax and NI lines reflect the country's bands

Tips

• The UK is the default so existing tenants keep working with no change
• Keep a separate config per jurisdiction — don't overload one country's bands
• Update bands at the start of a tax year; historical runs keep the bands that were in effect
