PayslipIQ uses each country's authoritative tax-and-payroll rules to explain a payslip in plain English. We never invent a rule. If a rule is uncertain — for a specific state, province, award, or employer setup — we say so and point you to the authority.
Each country experience is bounded to that country's rules. We do not mix.
Federal: IRS Pub. 15-T withholding tables and IRS Pub. 15. FICA: 6.2% Social Security up to the wage base, 1.45% Medicare, 0.9% Additional Medicare on wages over $200,000 YTD. State: each state’s revenue agency. Pre-tax stack handled in IRS-aligned order.
PAYE income tax bands and personal allowance per HMRC. National Insurance Class 1 thresholds and rates. Tax codes including K codes, BR, NT, and emergency codes. Student loan plans. PayslipIQ UK runs on payslipiq.co.uk.
Revenue.ie PAYE bands and standard rate cut-off (SRCOP). USC bands and surcharges. PRSI classes A, S, J. Tax credits and how they reduce tax due. Calculator not yet live.
CRA federal brackets with provincial overlays. CPP and CPP2 employee contributions. EI premiums. RRSP pre-tax handling. Province-specific rules will not be applied until the calculator is live.
ATO PAYG withholding tables. Tax-free threshold and HELP/HECS thresholds. Superannuation guarantee. Medicare levy and surcharge. Awards and enterprise agreements outside the tool’s scope until launch.
Tax tables, contribution thresholds, and band rules change every tax year. PayslipIQ stamps the tax year and the last-verified date on every numeric output inside the country experience.
We only reference government and authority sites for tax rules. Educational publishers are not the authority on a tax rule.
