About Cross State Payroll

Cross State Payroll is an independent calculator built to answer one question state revenue office calculators can’t: what happens to your payroll tax threshold when your wages span more than one Australian state, or when your business is grouped with related entities.

What this site is not

This is not a government website, and it is not affiliated with, endorsed by, or connected to Revenue NSW, the State Revenue Office Victoria, the Queensland Revenue Office, or any other Australian revenue authority. It is not a registered tax agent service, and using it does not constitute tax advice. It is not registered as an Australian company and holds no ABN — treat every figure it produces as an estimate to confirm elsewhere, not a final answer.

How the calculations work

Every calculation runs entirely in your browser. Nothing you enter — wages, grouping status, contractor flags — is sent to a server or logged anywhere. The underlying formulas are pure functions, unit tested against worked examples published directly by Revenue NSW, the State Revenue Office Victoria and the Queensland Revenue Office.

How rates are kept current

Rates and thresholds live in a single configuration file, each entry carrying the official source URL it was checked against and the date it was last verified:

• NSW: 5.45% above $1,200,000 — last verified 2026-08-12, via Revenue NSW.
• VIC: 4.8500000000000005% above $1,000,000 (phasing out for larger employers) — last verified 2026-08-12, via State Revenue Office Victoria.
• QLD: 4.75% above a deduction phasing out from $1,300,000 — last verified 2026-08-12, via Queensland Revenue Office.

Rates change on 1 July each year. When they do, the configuration file is the only thing that needs to change — nothing is hardcoded elsewhere in the calculators.

What’s not modelled yet

WA, SA, TAS, ACT and NT don’t have dedicated calculators yet — their wages count toward your total Australian wages (which affects your NSW, VIC and QLD thresholds) but this tool doesn’t calculate a liability for those states themselves. Deemed contractor wages aren’t calculated at all — the exemption conditions are too fact-dependent for a calculator to assess responsibly, so contractor payments are flagged as a risk, not priced. A small number of edge cases (Victoria’s regional rate and large-employer surcharges, exact QLD part-year proration) are noted directly next to the relevant result rather than silently estimated.
