How to Do Payroll for Small Business Australia — Step-by-Step Guide for Employers

You've hired your first employee. Good. Now the ATO wants its cut, your employee expects a payslip, and someone keeps muttering "STP Phase 2." Small business payroll Australia-style isn't complicated — but it has five hard obligations, each with real penalties attached. Get them right every single pay run, or wear the consequences.

What Small Business Payroll in Australia Actually Involves

Three regulators touch your payroll. The ATO handles tax and super. Fair Work Australia governs wages and payslips. Your state or territory covers long service leave and workers' comp. The checklist is short — but ignoring any item on it triggers penalties, not warnings.

Every Australian employer — regardless of size — must meet five obligations on every pay run: pay at least the applicable minimum wage or award rate, withhold the correct PAYG tax, pay the super guarantee on time, report via Single Touch Payroll, and issue a compliant payslip. Miss one and you're exposed.

Step-by-Step: Running Payroll for Your First Employee

Take James — a Brisbane café owner who hired his first kitchen hand and figured a spreadsheet would handle it. Three pay runs later, he'd underpaid super twice and had no TFN Declaration on file. Here's the sequence that fixes that from day one.

1. 1

   Collect a Tax File Number Declaration
   Before the first payment, your employee must complete a Tax File Number Declaration. Without it, you're legally required to withhold at the top marginal rate: 47%. Lodge it with the ATO within 14 days of receipt.
2. 2
   Calculate gross pay
   Hourly staff: hours worked × hourly rate. Salaried staff: annual salary ÷ pay periods per year. Check your Modern Award or Enterprise Agreement — base rates, penalty rates, and allowances all count toward gross.
3. 3
   Withhold PAYG tax
   Use the ATO's 2025–26 PAYG withholding tax tables. The correct figure depends on pay frequency, whether the employee claims the tax-free threshold, and whether HECS/HELP applies. Don't estimate — the tables exist precisely so you don't have to.
4. 4
   Calculate superannuation
   Super sits on top of gross pay — not inside it — unless the employee has a salary sacrifice arrangement. The rate is 11.5% of ordinary time earnings (OTE) for 2025–26. Overtime is generally excluded from OTE; commissions and allowances depend on the Award.
5. 5
   Issue a compliant payslip
   The Fair Work Act gives you one business day after payday to issue a payslip. Required fields: employer name and ABN, employee name, pay period dates, gross and net pay, PAYG withheld, super accrued, and any allowances or deductions.

Payslip Requirements and STP Reporting for Small Business

Single Touch Payroll Phase 2 is mandatory for every Australian employer. No size exemptions. Every pay event must reach the ATO digitally on or before the payment date — including sole traders with a single casual on the books.

Small employers with 19 or fewer staff were given extra STP Phase 2 transition time. That window has closed. Manual payroll is now non-compliant. Most small businesses use payroll software or a compliant payslip generator that handles STP automatically, cutting the reporting burden entirely.

💡 Did You Know?

ATO data-matching flags discrepancies between your STP reports and your employees' tax returns automatically. If your STP figures don't match what you actually paid, expect a call. The system was built specifically to catch gaps.

On records: payslips and payroll data must be stored for 7 years under both the Fair Work Act and ATO rules — gross pay, deductions, super contributions, leave balances. Digital records qualify. See the full guide to payslip record keeping in Australia for exactly what to keep and how long.

The most common errors aren't malicious. Employers forget to update the payslip template when the super rate changes, or omit YTD totals. Both are fixable — but they leave you in breach of the Fair Work Act until corrected. Don't wait for an audit to find them.

PayslipMate generates Fair Work-compliant payslips with PAYG, super, and YTD totals pre-calculated — ready in under 2 minutes. Built specifically for Australian employers.

The Bottom Line

Five obligations. No exceptions. Wages, PAYG, super, STP, payslips — get them right on every pay run and you stay on the right side of both Fair Work and the ATO. Use a tool built for Australian compliance and remove the guesswork entirely.

Frequently Asked Questions

How often do small businesses in Australia have to run payroll?

No fixed legal frequency — but the pay period must be agreed in writing and applied consistently. Weekly, fortnightly, and monthly are all standard. Each pay event triggers an STP submission to the ATO on or before payment date, so more frequent payroll means more frequent reporting.

Do I need payroll software to run payroll as a small business in Australia?

Not legally required. But STP Phase 2 demands digital ATO reporting, which makes paper-based payroll effectively obsolete for any employer with staff on the books. Most small businesses use payroll software or a compliant payslip generator. The cost is trivial next to an SGC charge or a Fair Work penalty.

What happens if I pay super late as a small business employer?

Late super triggers the Superannuation Guarantee Charge — and it's not tax-deductible. On top of the missed amount, you'll owe 10% annual interest plus a $20 per-employee, per-quarter administration fee. The ATO actively pursues SGC debts from small employers. It's an enforcement priority, not an afterthought.

Can I use a payslip generator instead of full payroll software?

Yes — for many small businesses, a compliant payslip generator covers the core obligation. You still need to calculate PAYG withholding correctly, submit via STP, and pay super on time. But if you're not running complex leave accruals or multi-award scenarios, a purpose-built generator like PayslipMate handles the payslip and STP reporting without the overhead of full payroll software.

Bottom Line

Australian payroll compliance isn't optional — and ignorance of the rules isn't a defence Fair Work or the ATO will accept. Small business employers are held to the same standard as large ones on wages, PAYG, super, STP, and payslip requirements.

• Pay at least the Award or NMW — never below it
• Withhold the correct PAYG and remit it to the ATO on schedule
• Pay super by the quarterly deadline — late means SGC
• Issue a payslip within one business day of every pay run
• Report every pay event via STP Phase 2 before funds hit employee accounts
