Employer Lump Sum Payments in Australia: What To Pay and When

Lump sum payments can pop up at key moments in the employment lifecycle - when someone leaves, when you settle a dispute, or when you correct historical underpayments.

If you’re running a small business in Australia, it’s important to know which lump sums you must pay, which ones are discretionary, and how to handle tax, superannuation and payslip reporting correctly.

In this guide, we’ll walk through the main types of employer lump sum payments, when they apply, how they’re taxed and reported, and the documents you’ll want in place to manage risk and stay compliant.

What Is An Employer Lump Sum Payment?

In simple terms, a lump sum payment is a one-off amount you pay to an employee (or former employee) outside of their usual pay cycle. It’s different to wages or salary because it’s not tied to ordinary hours in a particular period.

Common scenarios include finalising employment (redundancy, termination, resignation), settling a claim, cashing out leave, or paying a backpay adjustment.

While “lump sum” describes the way the money is paid, the rules that apply will depend on what the payment is for - for example, a redundancy payment is treated very differently to a bonus or a payment for unused annual leave.

When Do Employers Typically Make Lump Sum Payments?

1) Ending Employment (Final Pay)

Most final pays include some lump sum elements. Depending on the reason for ending employment and the applicable award or agreement, this could include:

• Accrued but unused annual leave (and annual leave loading, where it applies)
• Accrued long service leave (if the employee is eligible under state or territory laws)
• Payment in lieu of notice (if you ask the employee to finish immediately rather than work out their notice period)
• Redundancy pay (if the termination is a genuine redundancy and the business isn’t exempt)

If you decide not to require an outgoing employee to work their notice period, the amount you pay instead is a Payment In Lieu Of Notice. This is typically treated differently to wages for tax and super purposes, so it’s important to categorise it correctly in your payroll system.

2) Cashing Out Leave

Some awards and agreements allow employees to cash out a portion of annual leave instead of taking time off. This creates a one-off lump sum in the pay period it’s paid. Make sure you follow the rules in the relevant award or enterprise agreement, and keep written records of the employee’s request and your approval.

For a refresher on the rules and risks, see the overview on cashing out annual leave.

3) Backpay Or Underpayment Corrections

If you identify that an employee has been underpaid (for example, because an award rate changed or a classification was incorrect), you’ll generally make a lump sum backpay to fix the error. Treat the payment carefully - it needs to be taxed and reported in line with the earnings it relates to, not simply as “extra wages” today.

4) Bonuses And Incentives

Bonuses are also commonly paid as lump sums, whether discretionary or based on KPIs. The way they’re treated for superannuation and tax can depend on whether they’re considered ordinary time earnings.

5) Ex Gratia Or Settlement Payments

Sometimes, employers make a one-off payment as part of a negotiated exit or to resolve a dispute. These are often called “ex gratia” payments (a goodwill payment). Even though they’re discretionary, you’ll still need to consider tax treatment, super, documentation and release terms. For context, here’s a practical guide to ex gratia payments from an employer perspective.

How Are Employer Lump Sum Payments Taxed And Reported?

Not all lump sums are taxed the same way. Accurate categorisation in your payroll software and Single Touch Payroll (STP) reporting is critical.

Employment Termination Payments (ETPs)

Some lump sums paid on termination fall under the “employment termination payment” (ETP) category (for example, certain ex gratia amounts or payments in lieu of notice in some circumstances). ETPs have specific tax treatment and need to be reported in the correct ETP category through STP.

Unused Annual Leave And Long Service Leave

Unused annual leave and long service leave that’s paid out on termination is taxed differently to ordinary earnings. It’s usually reported under specific “lump sum” labels in STP. The tax rate can depend on the employee’s circumstances and the portion of leave being paid.

Redundancy Payments

Genuine redundancy payments are subject to special tax concessions up to a capped amount, with any excess potentially taxed as an ETP. Make sure you’ve confirmed the termination meets the definition of a genuine redundancy, and keep records of how you calculated the amounts.

Bonuses And Backpay

Bonuses and backpay adjustments paid as lump sums are generally taxable as salary and wages in the period they are paid (though backpay may also need to be reported against the correct historical categories). Check your award or agreement for any special provisions that apply to backpay.

Do Lump Sums Attract Superannuation?

Whether superannuation is payable depends on whether the payment counts as Ordinary Time Earnings (OTE). As a rule of thumb:

• Most regular bonuses connected to ordinary hours are OTE (and attract super).
• Unused annual leave and long service leave paid on termination are generally not OTE (so super is not usually payable on those components).
• Redundancy payments are not OTE.
• Payment in lieu of notice can be tricky - check your obligations carefully.

If you’re unsure, it’s a good idea to compare the payment against how OTE works in practice. This explainer on Ordinary Time Earnings is a useful starting point, and this guide on super on termination payments clarifies common edge cases.

What Should Final Pay Include When Someone Leaves?

Final pay needs to be correct, timely and clearly itemised. The contents will vary depending on the reason for exit, the applicable award or enterprise agreement, and any contract terms, but typically includes:

• Outstanding wages up to the last day worked
• Accrued but unused annual leave (and leave loading, if applicable)
• Accrued long service leave, subject to eligibility under state or territory law
• Any authorised expense reimbursements
• Payment in lieu of notice (if applicable)
• Redundancy pay (if applicable)

For a step-by-step checklist, many small businesses find this overview on calculating final pay helpful. If the employee has resigned, different entitlements can apply - here’s a quick refresher on annual leave on resignation from an employer point of view.

If you choose to end the employment immediately, ensure your Payment In Lieu Of Notice is calculated correctly and reported in the right category for STP and tax purposes.

How To Manage Employer Lump Sum Payments Safely

1) Identify The Payment Type First

Start by asking: what is the lump sum for? Is it an entitlement (e.g. redundancy pay), a contractual amount (e.g. a sign-on bonus), a corrective payment (backpay), or discretionary (ex gratia)? The classification drives everything else - from tax and super to how you describe it on the payslip.

2) Check The Legal Basis (Contract, Award, Law)

Review the employee’s contract, your workplace policies, any applicable modern award or enterprise agreement, and the Fair Work Act requirements. This helps confirm what must be paid, how it’s calculated, and any notice or consultation steps (for example, in a redundancy process).

3) Calculate Carefully (And Keep Your Records)

Use reliable payroll calculations for leave accruals, redundancy, and notice periods. Keep a working paper that shows your calculations, the inputs, and the sources (contract terms, award clauses). Good records are essential if the figures are questioned later.

4) Confirm Tax, Super And STP Reporting

Make sure the payroll category is correct so withholding, super and STP lodgements are right the first time. Misclassifying payments can lead to additional tax liabilities or super penalties.

5) Use Clear Documentation

For negotiated exits, settlements and ex gratia payments, put the terms in writing and consider a Deed of Release. This is a common way to document a clean break, including mutual releases, confidentiality and return-of-property obligations.

6) Pay On Time And Provide Itemised Payslips

Final pays must be provided within the relevant timeframe (check your award or agreement). Itemise each component clearly on the payslip, including any lump sum codes where required.

7) Communicate Respectfully

Explain how the payment was calculated and what each line represents. This can prevent confusion or disputes, especially in sensitive scenarios like redundancies.

Common Employer Lump Sum Payments: Quick Reference

Payment In Lieu Of Notice

When you decide not to have an employee work out their notice period, you’ll typically pay an equivalent amount instead. This is distinct from wages and needs careful treatment for tax and super. You can check practical points in this guide to Payment In Lieu Of Notice.

Redundancy Pay

Genuine redundancies can trigger statutory redundancy pay (unless an exemption applies, such as a small business exemption). The amount generally scales with the employee’s length of service. Ensure you follow any consultation requirements in the applicable award or agreement, and consider whether redeployment options are available before finalising the decision.

Unused Annual Leave And Leave Loading

Unused annual leave is usually payable on termination. Some awards provide for leave loading to be paid on leave taken and/or on leave paid out - check your instrument. If the employee is resigning rather than being terminated, the entitlements can differ; here’s a refresher on annual leave on resignation.

Long Service Leave

Long service leave is governed by state and territory laws. Employees may be entitled to a payout of unused long service leave on termination based on their service and the local legislation. Calculate using the correct jurisdiction’s rules and keep evidence of service dates and prior service recognition (if any).

Bonuses And Commissions

Bonuses, commissions and incentives are commonly paid as lump sums. Whether these attract super will depend on if they’re OTE. Ensure your employment contracts and commission plans spell out how and when these amounts are earned and payable, and the impact of termination on eligibility.

Backpay Adjustments

When correcting underpayments, you’ll usually process a single lump sum that covers the period of underpayment. You should also consider whether interest is payable under the applicable instrument or as part of a remedial agreement.

Ex Gratia And Settlement Payments

These discretionary payments need careful documentation. In addition to tax and super considerations, settlement terms should address confidentiality, non-disparagement, return of property, and mutual releases. As noted, see the employer-focused guide to ex gratia payments for context.

Essential Documents To Manage Lump Sum Payments

You can reduce risk and confusion by having the right documents in place before and during a lump sum scenario:

• Employment Contract: Sets out notice periods, bonus or commission rules, and any leave loading. Clear terms help avoid disputes at exit.
• Workplace Policies: A staff handbook or policies can cover leave management, cashing out leave, resignations and performance processes.
• Redundancy/Termination Letters: Written notice of termination, reasons (where appropriate), and a breakdown of final entitlements.
• Separation Agreement or Deed of Release: For negotiated exits or settlements, a Deed of Release documents the lump sum, mutual releases and post-employment obligations.
• Calculation Worksheets: Internal records showing how you arrived at each component (leave balances, redundancy, notice).
• Payroll/Pay Advice: Itemised payslips with the right STP labels and categories.

If you’re ever unsure whether a lump sum attracts super or how to classify it in payroll, comparing it to Ordinary Time Earnings and checking your position on super on termination payments are practical first steps.

Practical Tips To Stay Compliant (And Avoid Disputes)

• Plan the exit process: For terminations and redundancies, map your steps before you act. Build in time for consultation where required.
• Check the correct instrument: Confirm whether an award or enterprise agreement applies and follow it precisely.
• Be consistent: Apply your policies consistently to reduce claims of unfair treatment.
• Document everything: Keep a paper trail of calculations, communications and approvals - especially for cashing out leave and ex gratia arrangements.
• Use clear, neutral language: Letters and emails should be factual and respectful. Avoid commentary that could be misread in a later dispute.
• Close out access and obligations: In settlement scenarios, address return of property, confidentiality and non-disparagement as part of the agreement.
• Double-check your final pay: Before processing, compare your checklist against a trusted resource on calculating final pay to catch common omissions.

Key Takeaways

• “Employer lump sum payments” covers several different items - from notice in lieu and leave payouts to redundancy, bonuses, backpay and ex gratia - and each has different tax, super and reporting rules.
• Classify the payment first, then confirm the legal basis (contract, award, law) before you calculate. This drives how you treat it for super and STP.
• Final pay usually includes outstanding wages, unused annual leave, and sometimes long service leave, payment in lieu, and redundancy where applicable.
• Whether a lump sum attracts super depends on whether it’s Ordinary Time Earnings - check your position carefully on items like notice in lieu and bonuses.
• For negotiated exits or settlements, use a clear written agreement such as a Deed of Release and keep thorough records of calculations and approvals.
• Accurate categorisation and itemised payslips reduce the risk of disputes or compliance issues and make STP reporting straightforward.
