Payroll for Small Businesses: STP, Super, and Compliance Made Simple 

Single Touch Payroll Explained

Single Touch Payroll (STP) is the ATO’s system for reporting payroll data. Each time you pay your employees, your payroll software sends the ATO a report. That report covers wages, PAYG withholding and super contributions.

Every employer with staff must report through STP. You no longer prepare end-of-year payment summaries for your team. Instead, your software lodges the data on or before each payday.

At the end of the financial year, you must finalise your STP data by 14 July. Your employees then see their income statements in myGov. If you skip finalisation, your staff cannot lodge their tax returns with confidence.

How to Do Payroll for the First Time

First-time payroll feels complex, but a clear checklist keeps it simple. Follow these steps before your first pay run:

1. Register for PAYG withholding with the ATO.
2. Choose STP-enabled payroll software.
3. Collect each employee’s tax file number declaration and super fund details.
4. Confirm the correct award, pay rate and employment type.
5. Run your first pay, then lodge your STP report.

Many owners choose expert help at this stage, since early errors tend to repeat every pay cycle. If you want a safe start, specialist payroll services in Australia can set up your system correctly from day one.

Super, PAYG Withholding, Awards and Leave

Four obligations sit behind every pay run. Each one carries its own rules and deadlines.

Superannuation Guarantee

You must pay super for eligible employees on top of their wages. The current rate is 12% of qualifying earnings. Under Payday Super, which started on 1 July 2026, super must reach the employee’s fund within 7 business days of each payday. A new employee’s first contribution has a 20 business day window. A late quarterly habit no longer works.

PAYG Withholding

You withhold tax from each pay and send it to the ATO. The amount depends on the employee’s earnings and tax declaration. Your payroll software calculates it, but you must enter accurate details.

Award Rates

Most employees fall under a modern award or enterprise agreement. Awards set minimum pay, penalty rates, overtime and allowances. Fair Work updates these rates each year, usually from 1 July.

Leave Entitlements

Full-time and part-time employees accrue annual leave and personal/carer’s leave. Casual employees receive a loading instead of paid leave. When someone leaves, you must also pay out their accrued leave.

When to Outsource Payroll

You can run payroll yourself with two or three staff. However, the workload grows quickly. Watch for these signs that you should outsource:

• You spend hours each week on pay runs instead of your business.
• Your staff work varied shifts, so penalty rates confuse you.
• You missed a super payment or an STP deadline.
• You plan to hire more people soon.

Outsourcing hands the technical work to a registered professional. Dedicated support for payroll for small businesses keeps your pay runs accurate and your reporting on time. You keep control of your team, while an expert handles the rules.

How Bundled Payroll and Bookkeeping Reduce Errors

Payroll and bookkeeping share the same numbers. Wages, super and withheld tax all appear in your accounts. When two different providers handle them, data often falls out of sync.

A single team removes that gap. Your bookkeeper reconciles payroll liabilities as they arise, so your BAS matches your STP reports. As a result, you catch mistakes before the ATO does, and you avoid penalties and interest.

Integrated payroll and bookkeeping services also give you one point of contact. You save time, you see your true labour costs, and you stay ready for tax time.
