An Australian payroll engagement letter that says who moves the money

Payroll is the engagement where a mistake reaches someone other than the client: an employee paid wrongly, a payment to the tax authority made late. The letter decides whose mistake it was.

A payroll engagement letter sets the terms on which a firm runs a client's payroll: the cut-off for changes, approval before every pay run, who moves the money, and the fact that the liability stays with the employer. Firms send it before the first run. The template below covers each of those clauses, free in Word and PDF.

Get started

Most payroll disputes are about timing. A pay change arrives the morning of the run, a new starter is mentioned after the fact, a leaver's final payment is agreed on the phone. None of it is anyone's bad faith; all of it is avoidable with a cut-off written down in advance.

The other thing the letter must be honest about is liability. Running the payroll does not make you the employer. PAYG withholding and the superannuation guarantee remain the employer's obligations, whoever runs the payroll. The letter should say so, and make the client responsible for funding the payroll by a stated time.

What a payroll letter has to pin down

Five clauses. Each one is the answer to a phone call you would otherwise take on payday.

  1. 1

    The cut-off, and what misses it

    Hours, starters, leavers and pay changes by a stated time before each payday. Anything later goes into the next run, or is processed as an extra run at an extra fee.

  2. 2

    Approval before every run

    Send a summary before each pay run and finalise nothing until the client approves it. The approval is the client confirming the figures, and it is the record you will want if one is wrong.

  3. 3

    Who moves the money

    Say who pays net wages and who makes PAYG withholding payments to the ATO on your withholder cycle, and by when the funds must be available. PAYG withholding and the superannuation guarantee remain the employer's obligations, whoever runs the payroll.

  4. 4

    Pensions and the year end

    Name what you calculate and what you file: superannuation guarantee contributions, which since 1 July 2026 must reach the employee's fund within seven business days of each payday, and the Single Touch Payroll finalisation, due by 14 July for arm's length employees, with later dates for closely held payees. Deadlines the client has never heard of are the ones that get missed.

  5. 5

    Worker status is the client's decision

    Whether someone is an employee or a contractor, and what they are entitled to under employment law, is a question for the client and their advisers. The letter should say you process the payroll on the basis they give you.

The payroll engagement letter

Written for Australia. The downloads are the same text, as a Word document to edit and a PDF to put on your letterhead.

[Firm letterhead]

[Date]

[Client name]
[Client address]

Dear [Client contact],

The engagement

We will process the payroll of [Client name] on a [weekly / fortnightly / monthly] basis for approximately [number] employees, beginning [date]. For each pay run we will calculate gross pay, deductions and net pay, provide payslips, and prepare Single Touch Payroll pay events on or before each payday. At the year end we will prepare the Single Touch Payroll finalisation, due by 14 July for arm's length employees, with later dates for closely held payees.

Changes and approval

You will send us hours, new employees, leavers and any change to pay or deductions by [time] on [day] before each payday. Changes received after that go into the following pay run, unless you ask for an additional run, which is charged at [rate].

Before each pay run we will send you a summary for approval. We will not finalise the payroll until you have approved it, and your approval confirms that the figures are correct.

Payments

You are responsible for paying net wages to employees and for making PAYG withholding payments to the ATO on your withholder cycle, [unless you instruct us to initiate those payments from your account, in which case you will ensure the funds are available by [time] on [day]]. We will calculate superannuation guarantee contributions, which since 1 July 2026 must reach the employee's fund within seven business days of each payday; paying them on time remains your responsibility.

Your responsibilities

You remain the employer and are legally responsible for withholding and paying the amounts due on time. You are responsible for the accuracy and completeness of the information you give us, including each worker's status as an employee or contractor, their rates of pay and their entitlements under employment law. We will rely on that information without verifying it.

When an employee leaves, you will tell us their last day and any final payments by [date], and we will prepare the termination payment and the final pay event. You will provide your authorisation for us to act as your registered BAS agent.

What is not included

This engagement does not include employment law advice, deciding whether a worker is an employee or a contractor, benefits administration, bookkeeping, or dealing with any inspection, audit or enquiry by the ATO or any other authority. We will agree any of these separately.

Fees

Our fee is [amount] in Australian dollars per pay run, invoiced [monthly], payable within [number] days. Year-end work and additional pay runs are charged at [rate] and agreed with you first.

Ending the engagement

Either of us may end this engagement on [number] days' written notice. We will complete the pay runs due in that period and provide your payroll records in a usable format.

Confidentiality and your employees' data

Payroll records contain your employees' personal information. We hold and process it on your behalf in accordance with the Privacy Act 1988, only for the purpose of running your payroll, and retain it for [number] years.

Agreement

Please sign and return a copy of this letter.

Yours sincerely,
[Name], [Firm name]

Agreed for [Client name]:

Before you use this

Supplied as-is, with no guarantee. These templates are general information, not legal advice, and not a substitute for it. Have your own legal adviser review and adapt one to your practice and your jurisdiction before you put it in front of a client. FirmHello accepts no responsibility or liability for any use made of them.

Running an Australian payroll for a client

Every pay run is reported through Single Touch Payroll, and the year closes with a finalisation declaration due by 14 July. Closely held payees follow other dates: 30 September where the employer also has arm's length employees, and the payee's return due date for small employers with closely held payees only.

The letter's cut-off matters more since Payday Super began on 1 July 2026. Contributions must reach the fund within seven business days of payday, so a late change now affects super as well as wages.

Pay slips within a working day

Fair Work rules require a pay slip within one working day of payday, even when the employee is on leave, with prescribed content including super contributions and the fund they go to. Say whether you issue pay slips or the client does.

Seven years, not five

Time and wages records must be kept for seven years under the Fair Work rules, longer than the ATO's general five. The letter should say who keeps them and how the client gets them back when the engagement ends.

Super records start on payment

For employee super contributions, the ATO's five-year retention period starts from the date of each contribution, and for fund choice from engagement or the employee's choice. File those records with the pay run they belong to.

Private records, controlled access

Fair Work treats employee records as private: open to the employer, payroll staff, the employee and authorised people such as an accountant. Employees may ask to see theirs even after leaving, so say how those requests reach you.

Where payroll engagements go wrong

The change on the morning of the run

A pay rise agreed on the phone, mentioned after the payroll is final. A cut-off turns that from your error into a correction in the next run.

The account that was short

Payments bounce because the client funded the account a day late, and the late-payment penalty arrives addressed to them. The letter should have said so before it happened.

The contractor who was an employee

A worker is paid gross for a year and the authorities disagree with the arrangement. The letter should say status was the client's determination, not yours.

Questions about payroll engagement letters

If we run the payroll, are we liable for late payments?

Generally not for the tax itself, which stays with the employer. You are responsible for doing the work you agreed to, on time and with care, which is why the letter should set out exactly what that work is and when the client has to fund it.

Do I need to be registered to run payroll for clients?

Yes. Payroll services that involve Single Touch Payroll reporting, PAYG withholding or the superannuation guarantee are BAS services, and providing them for a fee requires registration with the Tax Practitioners Board as a BAS agent or tax agent, or working under the supervision of one.

Should each pay run be approved in writing?

Yes, in some recorded form. An approval in your portal against the exact summary the client saw is the strongest version; an email reply is weaker but far better than nothing.

Can one letter cover payroll and bookkeeping?

It can, with a separate schedule for each service. The payroll schedule needs its own cut-off and funding clauses, which do not belong in a bookkeeping letter.
