SA Payroll Tax for Accountants

SA payroll tax depends on your client’s Australia-wide taxable wages, group position and South Australian wages. Registration starts above $1.5 million annually. Calculate the applicable rate and deduction separately, then reconcile the employer’s returns with its actual full-year wages.

Check the SA Employer’s Registration

Assess registration using the employer’s Australia-wide taxable wages, including the relevant payroll tax group. A group member paying South Australian taxable wages can need registration even when its own wages fall below the threshold. RevenueSA’s registration guidance explains that group test.

Collect the employing entity’s ABN and South Australian taxpayer number. Match them to previous returns and the payroll records. Confirm when employment starts, which states receive wages and whether group membership changes. Ask for the designated group employer’s details when the client belongs to a group.

For a new registration, gather actual and estimated Australian wages and the historical wages RevenueSA requests. For an existing employer, compare its registered details and wage estimates with the current position. A change of employing entity or group membership needs attention before you reuse the previous deduction.

The national payroll tax guide explains the interstate context. Keep the South Australian calculation separate from the other jurisdictions’ returns.

Calculate the SA Taxable-Wages Position

Use Australia-wide annual taxable wages to determine the rate, then apply it to South Australian taxable wages after the permitted deduction. RevenueSA’s rates and thresholds lists the following figures.

The rate is nil up to $1.5 million of Australia-wide annual taxable wages. Above $1.5 million and up to $1.7 million, it varies from 0% to 4.95%. Above $1.7 million, the rate is 4.95%.

The maximum deduction is $600,000 annually or $50,000 monthly. The $1.5 million registration threshold is not the amount you subtract from wages. Interstate wages and part-year employment reduce the available deduction. Only the designated group employer claims the group deduction during the year, subject to annual allocation of unused entitlement.

For reporting years ending in 2026 or 2027, select the employer’s financial year and apply RevenueSA’s operative rates for that period. Check any changed allowance rates separately. For a later reporting year, use the rules that apply to that year instead of assuming a forecast rate is law.

A Fictional Interstate Workpaper

Assume an ungrouped employer employs throughout the financial year. All amounts below are invented. Its reconciled taxable wages total $2 million across Australia, with $1.2 million allocated to South Australia.

Workpaper line	Amount	Supporting record
SA wages and salaries	$1,060,000	Payroll totals reconciled to accounts
SA employer superannuation	$130,000	Contribution reports
SA taxable fringe benefits	$10,000	Payroll tax fringe-benefit calculation
Total SA taxable wages	$1,200,000	Sum of the preceding components
Interstate taxable wages	$800,000	Interstate payroll workpaper
Australia-wide taxable wages	$2,000,000	SA plus interstate totals
SA deduction	$360,000	$600,000 multiplied by $1,200,000 divided by $2,000,000
Net SA taxable wages	$840,000	$1,200,000 less $360,000
Annual SA payroll tax	$41,580	$840,000 multiplied by 4.95%

This follows RevenueSA’s interstate deduction calculation. Apply the group and part-year rules before using that formula for another client.

Retain the operative Payroll Tax Act 2009 version for the reporting period. Sections 10 and 11 govern taxable wages and South Australian allocation. Section 13 defines wages. Record the relevant provision beside each wage adjustment, with the underlying payroll or payment evidence.

Arrange RevenueSA Online Access

Use your own authorised account at the official RevenueSA Online login. Keep the employer’s authority to prepare and lodge returns in your engagement records. Confirm who can approve payment and lodge the annual reconciliation before assigning those tasks.

RevenueSA distinguishes registering a user from registering an employer for the payroll tax component. An existing user can arrange another employer registration without creating another personal account. For an already registered employer, confirm the correct business association and access through RevenueSA’s payroll tax access guidance.

If the employer’s account is missing, compare the selected business with the taxpayer number and ABN in your file. Ask the employer’s administrator to confirm your access. The official guidance links the user-access form and Change Business help. Do not use another person’s credentials or create a duplicate employer registration to bypass missing access.

If access still fails, check RevenueSA’s maintenance notice and contact its support through the access page. Supply the employer’s taxpayer number and organisation details, with the problem you encounter. Resolve the association before lodging against any account.

Support the SA Wage Exemptions

Support each excluded payment with the exemption condition and employee records. RevenueSA’s exemptions guidance distinguishes exempt wages from payments outside taxable wages. A payroll label such as parental leave does not establish the tax treatment.

For employer-funded maternity or adoption leave, apply the statutory eligibility and maximum equivalent of 14 weeks’ normal pay. Fringe benefits remain outside that exemption. Ordinary annual or sick leave taken during the absence does not become maternity or adoption leave.

Revenue Ruling PTA012 explains the evidence required under sections 53 and 54. Obtain the medical certificate or statutory declaration for maternity leave. Adoption leave requires the statutory declaration about custody or the adoption order. Match the approved leave, pay rate and exempt amount to the payroll entries.

Commonwealth Paid Parental Leave passed through by the employer has a different treatment from employer-funded leave. Identify that funding in the payment records. Keep an exclusion schedule showing each amount, legal basis and evidence location, so the reviewer can reproduce the treatment.

Prepare SA Monthly Returns

Prepare the monthly return from a reviewed wage workpaper and an agreed payment responsibility. Complete the steps in this order.

1. Collect the period’s wage components and reconcile them to payroll and accounting records. Include taxable amounts outside the ordinary salary total.
2. Review South Australian allocation, exemptions and the estimated deduction. Compare the annual wage estimate with actual wages to date.
3. Obtain the client’s approval of the return and confirm who authorises or makes payment.
4. Lodge through RevenueSA Online using the applicable return period. Compare the portal calculation with the reviewed workpaper before submitting.
5. Save the return declaration or payment advice. Confirm the payment reference, amount and scheduled or completed payment separately.

RevenueSA’s monthly return guidance requires a nil return when wages are below the estimated deduction for a period. Monthly returns and payment are generally due seven days after month-end. Weekend, public-holiday and approved extension conditions affect the actual deadline.

Use the official schedule for the employer’s reporting year. The financial year’s final wage month belongs in the annual reconciliation, without a separate monthly return. Lodging a return does not by itself complete an EFT or BPAY payment. Use the payment reference issued for that return and retain evidence that the employer pays it.

Reconcile the SA Year-End Account

Recalculate the annual liability from actual wages and compare it with returns and payments already recorded. Recheck interstate wages and group membership. Explain changes to the deduction or final rate before you seek approval.

In the fictional workpaper, annual liability is $41,580. If the account records $40,000 of payments and no other adjustments, the remaining tax is $1,580. If payments total $43,000 instead, the overpayment is $1,420. Identify any separate interest or penalty entries before treating the account balance as tax alone.

RevenueSA’s annual reconciliation guidance sets the return deadline at 28 days after financial year-end, with its next-business-day condition. Confirm the applicable payment obligation from the reconciliation and official return schedule. Assign payment to a named role in the client file even when your practice lodges the return.

Retain the calculation, approval and submitted reconciliation report. Match its assessed liability to the account and record the resulting payment or refund. RevenueSA reviews an annual overpayment before paying a refund to the nominated bank account.

If a discrepancy remains, modify the submitted annual reconciliation in RevenueSA Online and resubmit the corrected data. Use the official amendment help on the annual reconciliation page. Save both versions and the reason for the change, then confirm the corrected account balance and payment position.
