Embedded payroll infrastructure — Australia

Launch payroll in Australia without building Australian payroll.

Your platform is expanding into the hardest payroll country in APAC. Ledra Pay gives you government-sourced gross-to-net calculation and Single Touch Payroll lodgement behind one API — so you ship Australia in weeks, and your product stays yours.

What's at stake

Australia doesn't forgive payroll mistakes anymore.

Every platform that enters this market carries the same quiet fear: that an award rate, a super calculation, or a missed lodgement turns a launch into a headline. The rules are real, and they changed recently.

Since 1 Jan 2025Wage underpayment is a criminal offence

Intentional underpayment now carries criminal penalties for companies and officers — not just back-pay orders. "We didn't know the award" is not a defence.

Every pay eventSTP Phase 2 reports to the ATO in real time

Disaggregated gross, income types, and tax treatments are lodged with the tax office each payday. There is no quiet way to get it wrong.

121+ modern awardsThe most complex wage rules in the world

Penalty rates, loadings, allowances, and a 12% super guarantee — logic that has tripped up Australia's largest employers, with remediations in the hundreds of millions.

Your guide

We build Australian workforce compliance for a living. Now it's an API.

We know what it feels like to stare down a market entry where the compliance burden is larger than the product work. We've spent years inside Australian awards, superannuation, and statutory reporting — the exact logic that makes platforms hesitate at the border.

Ledra Pay packages that expertise as infrastructure: a government-sourced Australian regulation pack, computed by an accredited third-party payroll engine and wrapped in an auditable evidence chain, with the STP Phase 2 lodgement rail in build. The pack’s rules trace to the statutory register and every pay-run write is evidenced — calculation correctness sits with the accredited engine provider, while Ledra Pay orchestrates, evidences and lodges, and you keep payroll approval and the customer relationship.

Auditable core

Open-source calculation engine — regulation logic is inspectable end to end.

Maintained pack model

Production packs carry a named maintainer for statutory updates; country certification is pursued per pack.

Proven lineage

The same engine and compliance layer maintained across 11 EU countries in production.

Clean boundaries

We own calculation correctness. You own approval, experience, and your customer.

Who owns what

Calculate. Pay. File. Here's who does each stage.

The same three stages, mapped to owners — and to the AU setup checklist and STP & BAS lodgement in our guide. Green is Ledra Pay; grey is you (approval + disbursement); ochre is the ATO submission rail we're building.

Stage 1

Calculate

● Ledra Pay — live via the payroll engine
  • PAYG withholding, Medicare levy, STSL/HELP
  • 12% super guarantee, Modern Award interpretation
  • Payroll tax by state, leave & termination
Live · beta
Stage 2

Produce the artefacts

● Ledra Pay produces · you approve
  • Compliant payslips, generated at finalisation
  • ABA bank files for net pay
  • SuperStream contribution batches
  • The STP Phase 2 pay event — disaggregated gross, income types, tax treatments
Output ready
Stage 3

File to the ATO & pay

Today: your process  ·  Next: our orchestration
  • Net pay — your platform executes the ABA disbursement; we never move the money
  • Super — SuperStream contributions move through recorded pay-run states (Draft → Lodged → Paid); your platform settles them to the funds
  • STP Phase 2 → ATO over SBR — the accredited engine already lodges to the ATO through its SBR gateway; what Ledra Pay is proving is our orchestration of that lodge, verified to the gateway in sandbox (production certification pending)
  • Once certified, submitting through Ledra Pay is one API call — POST /pay-runs/{id}/submit — over the engine's existing rail, no re-integration
Engine rail live · our orchestration in sandbox
Ledra Pay does it You — approval + disbursement ATO lodge — engine's rail, our orchestration in sandbox
Australia is the furthest along: the accredited engine already lodges STP Phase 2 to the ATO over its SBR gateway — so the rail exists and is live. What Ledra Pay is finishing is our orchestration of that lodge: verified to the gateway in sandbox, with production certification the last step. Calculation and the STP pay-event are live today.

Live demonstration

This page is running the Australian pack right now.

Move the slider. Gross-to-net below is computed in your browser with resident PAYG scales, the Medicare levy, the low income tax offset, and the 12% super guarantee — and you can flip between the current pack and the legislated 1 July 2026 rates, exactly as pack versions work in the API.

$85,000

Indicative figures for an Australian tax resident claiming the tax-free threshold. Medicare levy at 2%, LITO applied, super guarantee at 12% of ordinary time earnings. From 1 July 2026 the 16% rate drops to 15% (legislated; 14% follows in 2027) — it ships as pack release AU-2026.1, selectable above. That toggle is how statutory updates work here: versioned packs, never silent changes. The production pack handles awards, allowances, salary sacrifice, HELP debts, and termination payments.

The embeddable component

The calculator above is the engine. This is the UI you ship.

The same payslip as a standard web component — drop it into your product, theme it with CSS variables (this one is wearing this page's palette), localise it. No payslip layout to build — and the same component renders a German Entgeltabrechnung in euros, or a UK / US / NZ payslip, when you switch country. The full set — onboarding, employees, leave, pay runs — runs in the component playground →

The plan

Three steps from here to your first Australian payrun.

01

Connect

Sandbox keys on day one. Onboard a tenant and employees over REST, attach the Australian regulation pack, and run your first calculation the same week.

Days, not quarters
02

Shadow run

Feed us the inputs from a live payrun. We return results; you diff them line-by-line against your incumbent. Zero production risk — the numbers earn your trust before anything goes live.

Proof before commitment
03

Go live

Switch calculation to the maintained pack, with STP lodgement following on the rail as it completes certification. Statutory updates arrive as versioned pack releases — scoped and predictable.

Maintained

Two ways this goes

Build a payroll engine, or build your product.

Going it alone

  • Multi-quarter build before the first compliant payslip
  • Hire and retain scarce AU payroll-compliance engineers
  • Own ATO DSP registration and SBR certification yourself
  • Track every award, threshold, and rate change — forever
  • Carry calculation liability under criminal wage-theft law

On Ledra Pay

  • First calculation in your sandbox this week
  • Maintained pack with a named compliance maintainer
  • STP rail and statutory outputs delivered as infrastructure
  • Annual statutory updates as versioned releases
  • Your team ships product — Australia becomes a config flag
