Payroll Deductions
Amounts withheld from an employee's or contractor's earnings to cover taxes, benefits, or other obligations.
What is Payroll Deductions?
Payroll deductions are amounts withheld from an employee's or contractor's earnings to cover taxes, benefits, or other obligations. These can be mandatory (like income tax or social contributions) or voluntary (like retirement savings or health insurance).
How it works
- Deductions are calculated during each payroll cycle and subtracted before issuing net pay. Common categories include:
- Mandatory Deductions: Income tax (e.g. PAYE in Nigeria, ISR in Mexico), Social security contributions (e.g. INSS in Brazil, NSSF in Kenya), Health or labor insurance (e.g. PhilHealth in the Philippines)
- Voluntary Deductions: Retirement plans, Stock purchases, Loan repayments, Union dues
- For global teams, deduction rules vary dramatically by country and employment status (employee vs contractor). Misapplying these can result in fines or lawsuits.
- Sigma automates deduction rules by country and handles documentation across 180+ jurisdictions.
Why it matters
- Payroll deductions are essential for:
- Legal compliance - Errors can trigger audits or penalties
- Accurate reporting - Essential for tax authorities and employees
- Transparency - Workers trust employers who clearly show gross vs net pay
- Cross-border scaling - Understanding local deduction norms avoids misclassification
Example
A U.S. company hires contractors in Colombia and Kenya. One contractor needs tax withholding; the other operates under a no-deduction agreement. Sigma applies the correct deduction policy per country, adds it to the contract, and reflects it in each pay stub.
