PAYG Withholding for Small Business: Your Complete Obligations Guide

Pay As You Go (PAYG) withholding is the system through which Australian employers collect tax from employees' wages and remit it directly to the ATO on their behalf. If you employ staff — even one person — you almost certainly have PAYG withholding obligations. Failing to meet them incurs penalties, interest charges, and can expose directors to personal liability.

What Is PAYG Withholding?

When you pay an employee wages, salary, or other income, you are required to withhold a portion of that payment and send it to the ATO. The withheld amount is credited against the employee's annual income tax liability when they lodge their tax return.

The system exists to ensure tax is collected in real time rather than as a lump sum at year end — and to ensure the ATO receives tax revenue before employees have a chance to spend it.

PAYG withholding applies to:

• Employee wages and salaries
• Director fees
• Certain payments to contractors who do not provide an ABN
• Payments to labour hire workers
• Certain payments to foreign residents

Registering for PAYG Withholding

You must register for PAYG withholding with the ATO before you make any payments subject to withholding. If you employ someone for the first time, registration should happen before their first pay day.

You can register as part of the business registration process through the Australian Business Register (ABR), or separately through the ATO's business portal.

There is no separate registration fee. Once registered, you receive a withholding payer number (which is often your ABN).

How Much Do You Withhold?

The amount you withhold from each payment is determined by:

• The employee's income tax bracket
• Any tax offsets the employee has claimed (e.g., low income tax offset, help debt repayment)
• Information provided by the employee on their Tax File Number (TFN) declaration or the ATO's withholding declaration

Tax File Number Declarations

When a new employee starts, they should complete a Tax File Number (TFN) declaration. The employee provides:

• Their TFN
• Whether they claim the tax-free threshold
• Whether they have a HELP/VSL/SSL debt
• Whether they have a study and training support loan

You use this information to calculate the correct withholding amount using the ATO's weekly tax table or withholding calculators.

If an employee does not provide a TFN declaration within 28 days of starting, you must withhold tax at the top marginal rate (currently 47%) until they do.

The Tax-Free Threshold

Australian residents can earn up to $18,200 per year without paying income tax (the tax-free threshold). If an employee claims the tax-free threshold, you withhold less tax. If they do not claim it (e.g., because they have another job), you withhold at a higher rate.

If an employee has two jobs and claims the tax-free threshold at both, they will receive an unexpected tax bill at year end. This is the employee's problem — but it is worth flagging to new employees who may not be aware.

Reporting PAYG Withholding Through Single Touch Payroll

Since 2019 (for large employers) and 2020 (for small employers), PAYG withholding is reported to the ATO through Single Touch Payroll (STP).

Under STP, each time you run payroll, your STP-enabled payroll software automatically reports each employee's wages, tax withheld, and superannuation to the ATO in real time. You no longer need to lodge separate PAYG withholding reports.

At year end, you "finalise" each employee's STP records — replacing the old payment summary / group certificate process. Employees then access their income statement via myGov to lodge their tax return.

STP Phase 2 expanded the reporting requirements from 2022, requiring additional information including:

• Detailed income type breakdown (salary, bonuses, commissions, etc.)
• Disaggregated gross wages
• Country codes for certain foreign income
• Additional tax withheld information

If your payroll software is not STP Phase 2 compliant, you are in breach of your reporting obligations.

When and How Do You Remit the Tax?

The frequency of PAYG withholding payments to the ATO depends on your withholding amount:

| Annual Withholding | Reporting and Payment Frequency | | ------------------- | ---------------------------------- | | $1 million or more | Weekly or fortnightly (to the ATO) | | $25,000 to $999,999 | Monthly | | Less than $25,000 | Quarterly (via BAS) |

For most small businesses, PAYG withholding is reported and paid as part of your quarterly Business Activity Statement (BAS).

Important: You remit the withheld amounts quarterly via BAS, even though STP reporting occurs with each payroll run. The STP reports are how the ATO tracks what has been withheld; the BAS is how you actually pay it.

Director Penalty Notices

One of the most serious consequences of PAYG withholding non-compliance is the Director Penalty Notice (DPN) regime. Company directors can be held personally liable for a company's unpaid PAYG withholding obligations if:

• The company fails to report withheld amounts (through STP or other means) within 3 months of the due date
• The company fails to pay withheld amounts when due

When the ATO issues a DPN, the director has 21 days to cause the company to pay the debt, enter into a payment plan, or appoint an administrator. If these steps are not taken, the ATO can recover the debt from the director personally.

This personal liability cannot be avoided by resigning after the DPN is issued. And in some circumstances, the personal liability crystallises before the DPN is issued (the "lock-down" DPN).

Payments to Contractors Without ABN

If you make payments to contractors who do not provide an Australian Business Number, you must withhold 47% of the gross payment and remit it to the ATO. The contractor then claims this as a credit against their income tax when they lodge their return.

Many small businesses miss this obligation because contractors who fail to provide an ABN often also fail to follow up — they claim the credit at tax time regardless.

You should always collect ABNs from contractors before making payments. No ABN = 47% withholding.

Common PAYG Withholding Mistakes

1. Not Registering Before First Payroll

Starting to pay employees without being registered for PAYG withholding is a breach from day one. The ATO can back-date obligations and apply penalties.

2. Incorrect Withholding Calculations

Using out-of-date tax tables, failing to account for HELP debts, or not applying the correct basis for part-year employees can result in systematic under or over-withholding.

3. Not Finalising STP Records at Year End

If you do not finalise each employee's STP income statement by the due date (typically 14 July for payroll software users, or later if on a deferral), employees cannot lodge their tax returns correctly.

4. Miscalculating Withholding for Allowances

Travel allowances and other allowances can be tricky. Some allowances are subject to withholding; others are not. Applying the wrong treatment can result in over or under-withholding.

5. Using the Wrong Treatment for Lump Sum Payments

Redundancy payments, unused annual leave, and other lump sum payments on termination have specific withholding rules that differ from ordinary wages.
