How to Register for Single Touch Payroll (STP) in Australia

If you're running a small business in Australia, getting Single Touch Payroll (STP) sorted might feel like just another box to tick—but it's a game-changer for simplifying your payroll reporting to the ATO. Whether you've got a handful of staff or a growing team, knowing how to register for Single Touch Payroll (STP) in Australia keeps you compliant, cuts down on paperwork, and avoids nasty penalties in 2026.

STP has been mandatory since 2019 for all employers, big and small, requiring you to report payroll info like salaries, PAYG withholding, and super contributions directly to the ATO each pay cycle. By 2026, with STP Phase 2 fully rolled out, it's easier than ever through compatible software, but you still need to set it up right. We'll walk you through the lot—step by step—so you can get registered quickly and focus on what matters: growing your business.

What is Single Touch Payroll (STP)?

Single Touch Payroll is the ATO's system for real-time payroll reporting. Instead of annual payment summaries, your payroll software sends employee payment details—including wages, tax withheld, and super—to the ATO on or before payday. It's been law since 1 July 2019, first for businesses with 20+ employees, then expanded to all employers.

In 2026, STP Phase 2 builds on this with closer ties to myGov, letting employees see their income statements instantly, and stricter rules on data accuracy to match super and tax records. No more end-of-year hassles—finalisation happens through STP too. For Aussies, this means less admin, but it demands accurate records from the get-go.

Why STP Matters for Your Business in 2026

• Compliance made simple: Report once per pay run, not yearly.
• Employee benefits: They access statements via myGov linked to ATO.
• ATO oversight: Real-time data helps spot issues early, like underpaid super.
• Penalties avoided: Fines start at $330 per employee per month for non-compliance, scaling up for repeats.

If you're a sole trader paying yourself wages or directors' fees, STP covers that too.

Who Needs to Register for STP?

Every Australian business paying wages, salaries, or incentives must use STP—regardless of size. That includes:

• Employers with even one employee (full-time, part-time, or casual).
• Businesses paying directors or owners via salary.
• Labour hire firms and those with closely held payees.

Even micro-businesses (under 5 employees) got a transition period back in 2019, but by 2026, everyone's on board with no exceptions. If you're not reporting yet, the ATO expects immediate action—deferrals are rare now.

Pre-Registration Checklist: Get Your Ducks in a Row

Before diving in, tick these off to avoid hiccups. STP setup relies on solid foundations.

1. Australian Business Number (ABN): Your business's unique ID—grab it from the ATO portal or BAS if you don't have it.
2. Authorised contact details: Name, phone, email of the person handling this (you, a director, or nominated employee).
3. myGovID for business: Link it via Relationship Authorisation Manager (RAM) on the ATO site for secure access.
4. Employee records: Up-to-date TFNs, DOBs, addresses, super funds, employment status (full-time, casual, etc.). Double-check foreign workers' visas too.
5. STP-ready payroll software: Popular ones like Xero, MYOB, QuickBooks are compliant—confirm with your provider.

Pro tip: Run a payroll audit now. Inaccurate TFNs can trigger ATO flags and audits.

Step-by-Step Guide: How to Register for Single Touch Payroll (STP) in Australia

Registration happens through your software and the ATO's online portals. It's straightforward if you're prepared—most do it in under an hour.

Step 1: Choose and Set Up STP-Enabled Software

Pick software that's ATO-registered for STP Phase 2 (all major Aussie providers are by 2026). Log in, find "STP Enable" or "ATO Connect" in settings, and activate it. Your software will generate a unique Software ID (SSID).

Step 2: Register Your Software with the ATO

Head to the ATO's Access Manager (log in with your ATO Business Portal credentials).

1. Go to "My hosted SBR software services."
2. Click "Notify the ATO of your hosted service."
3. Search for your software provider (e.g., Xero, MYOB) by name or ABN.
4. Enter your SSID from the software.
5. Hit "Next" and submit—ATO confirms instantly.

Can't access online? Call the STP helpline at 1300 852 232. Agents can do this for you if authorised.

Step 3: Connect and Test Your Setup

Back in your software, link to the ATO using the registered SSID. Run a test pay run (many tools offer this) to ensure data flows correctly—no employee payments needed yet.

Step 4: Start Reporting and Finalise End-of-Year

Your first real pay run sends data automatically. For June 30 finalisation (due by 14 July 2026):

• Review year-to-date totals.
• Mark employees as "finalised" in software.
• Submit declaration to ATO.
• Notify staff their myGov statements are ready.

In Xero, it's Payroll > End-of-Year > Finalise STP.

Common STP Reporting Requirements in 2026

Each pay run, report:

• Salaries, wages, allowances, leave.
• PAYG withholding.
• Super contributions (including guarantees).
• Deductions and lump sums.
• New hires' details pre-first pay.

Phase 2 adds worker classification checks (employee vs contractor) to curb dodgy gigs.

Troubleshooting Common STP Issues

Hit a snag? Here's how to fix it:

• SSID errors: Re-generate in software and re-register.
• Data mismatches: Update employee TFNs/DOBs immediately.
• Software not connecting: Check myGovID/RAM linkage; restart setup.
• Transition help: Small biz? ATO offers free webinars—check ato.gov.au.

Directors now face personal liability for repeated non-compliance under Phase 3 rules.
