PAYG withholding: a practical guide for Australian employers

PAYG withholding is the system employers use to deduct tax from payments to employees, some contractors, and office holders, then remit that tax to the Australian Taxation Office. If you pay wages, directors’ fees, or certain contractor invoices, you are almost certainly required to register for PAYG withholding, calculate the correct amount each pay cycle, report through Single Touch Payroll, and pay the ATO by your due date. Getting this right protects your cash flow, your staff, and your business from avoidable penalties.

Key takeaways

• Register for PAYG withholding with the ATO before making any payment that requires tax to be withheld.
• Use current ATO tax tables or STP Phase 2-enabled payroll software to calculate the correct amount.
• Withheld amounts are held on behalf of the ATO, not business income. Keep them separate from operating cash.
• Your payment cycle depends on your annual withholding: small (≤ $25,000) pays quarterly, medium ($25,001 to $1 million) pays monthly, large (> $1 million) pays within six to eight days of each withholding event.
• PAYG withholding is separate from Queensland payroll tax, which applies only once annual Australian taxable wages exceed $1.3 million.
• Worker classification matters. Labelling someone a contractor does not remove a withholding obligation if the arrangement is really employment.

What PAYG withholding is, and how it works

PAYG withholding is a federal tax collection system administered by the ATO. Each pay run, you work out gross pay, calculate the tax to withhold using ATO tax tables or approved payroll software, deduct that amount, and pay the net figure to the employee. You then report the withholding through STP and remit the tax to the ATO on your scheduled cycle.

The amount withheld depends on the worker’s earnings, whether they have claimed the tax-free threshold, whether they have a study or training support loan (HELP, VSL, SFSS, SSL, or the Australian Apprenticeship Support Loan, formerly the Trade Support Loan), their residency status for tax purposes, and the pay cycle. If an employee does not provide a tax file number, stricter withholding rules apply.

A practical point worth stressing: PAYG withholding is not business income. It is money held on behalf of the ATO until remittance. Businesses that treat it as working capital usually run into trouble when a BAS due date arrives.

Who needs to register for PAYG withholding

You must register with the ATO before the first payment that requires tax to be withheld. Registration is usually triggered when you hire your first employee, but it can also apply if you:

• pay salary, wages, bonuses, commissions, or allowances to employees
• pay directors’ fees or remuneration to office holders such as company secretaries
• have a voluntary withholding agreement with a contractor
• make a payment where a supplier has not quoted an ABN (no-ABN withholding rules)
• operate a labour hire arrangement or make payments under certain other specified withholding categories

Business size is not the deciding factor. A sole trader who hires one part-time admin assistant has the same registration obligation as a larger employer. If you operate more than one entity, remember that the registration belongs to the legal entity actually making the payment, not the trading name. A common example is a local tradesperson moving from sole trader to company structure who hires an apprentice: the withholding registration must sit under the correct ABN, with payroll settings to match.

When you must withhold tax from a payment

The obligation to withhold depends on the type of payment and the working arrangement, not the label on an invoice. Review every new payment arrangement against three questions: Is the recipient an employee, director, office holder, or genuine contractor? Have they quoted a valid ABN? Do any specific withholding rules apply?

Employees, company directors, and office holders

PAYG withholding applies to payments to employees (salary, wages, bonuses, commissions, allowances, paid leave) and, importantly, to directors’ fees and payments to office holders. Directors of family companies often assume that because they are also owners, their drawings are not subject to withholding. They usually are, if those drawings are properly characterised as directors’ fees or salary. Processing them correctly through payroll from the start avoids retrospective corrections and a larger-than-expected ATO liability at year-end.

PAYG withholding and superannuation guarantee are separate obligations. Withholding tax from a payment does not remove the need to assess whether super applies, and paying super does not remove the withholding obligation. Both usually apply to employee and director remuneration.

Contractors, including no-ABN and voluntary agreements

Most contractor payments do not require withholding, but some do. Withholding applies in three main cases:

• No ABN quoted: if a supplier does not provide a valid ABN on their invoice or other business document, you must generally withhold at the top marginal rate plus Medicare levy, unless an exception applies.
• Voluntary agreement: a business and an individual contractor can agree in writing for PAYG withholding to apply. This suits regular service providers who prefer progressive tax management.
• Labour hire and other specified payments: labour hire arrangements and payments wholly or principally for a person’s labour can trigger withholding, and often super, even where the worker has an ABN.

Do I need to withhold tax from a contractor?

Sometimes. The answer depends on the facts of the arrangement, not the label. The ATO and courts look at the whole relationship: who controls the work, who provides tools and equipment, whether the worker can delegate, how they are paid, and whether they genuinely run their own business. A worker can hold an ABN and still be treated as an employee for tax, super, and workplace law purposes.

Misclassification affects more than withholding. It can create liabilities for super guarantee, leave entitlements, workers compensation, and payroll tax. A common local scenario: a trade business engages a worker four days a week for eight months, provides the vehicle and uniform, directs daily work, and has an exclusive relationship. Even with an ABN and invoices, the arrangement may be employment in substance. The safest approach is to assess each arrangement before the first payment, document the decision, and review it if circumstances change.

How to register for PAYG withholding with the ATO

Register before the first relevant payment, not after. You can register through the Australian Business Register when applying for an ABN, through Online services for business, or through a registered tax or BAS agent. If your business structure changes, for example from sole trader to company, make sure the withholding registration sits under the new entity’s ABN.

Before you register, pull together:

• the exact legal entity that will employ staff (sole trader, company, trust, or partnership) and its ABN
• the expected date of the first payment
• the types of payees involved (employees, directors, contractors under voluntary agreements)
• your payroll software, set up to STP Phase 2 standards
• employee onboarding paperwork: tax file number details, super fund choice, employment contracts, pay rates, and award classifications

PAYG withholding registration is only one piece of payroll compliance. Superannuation, Fair Work obligations, leave accruals, payslip requirements, and workers compensation all sit alongside it. A business that registers for withholding but has not confirmed award rates or super arrangements is still exposed.

How to calculate the correct withholding amount

Correct withholding depends on accurate employee information and current ATO tax tables. Guess-and-round is not a method. Confirm each employee’s tax position at onboarding, configure payroll software correctly, and review settings each 1 July (or whenever the ATO updates its schedules during the year).

Using ATO tax tables and withholding schedules

The relevant ATO tax table or withholding schedule depends on the pay cycle (weekly, fortnightly, monthly) and the payment type. Ordinary salary and wages use the standard tables. Bonuses, commissions, back payments, termination payments, leave payouts, working holiday maker wages, and directors’ fees may require different schedules. Using the wrong schedule is a common source of under- or over-withholding, even where gross pay is right.

Most employers rely on STP-enabled payroll software to automate these calculations, which is sensible, but the software is only as accurate as its setup. If you run payroll manually or keep spreadsheets alongside software, the risk of a formula error repeating every pay run is real. For payments outside the routine (quarterly bonus, ETP, back pay), pause and confirm the correct treatment before lodging the pay event.

Factors that affect how much tax to withhold

Two employees on the same gross wage can have different withholding outcomes. Factors that change the calculation include:

• whether the employee has claimed the tax-free threshold
• residency status for tax purposes (not the same as visa status)
• whether the employee has a HELP, VSL, SFSS, SSL, or Australian Apprenticeship Support Loan debt
• the pay cycle (weekly, fortnightly, monthly)
• payment type (ordinary wages, overtime, allowances, bonuses, termination pay, leave loading)
• valid salary sacrifice arrangements, which can reduce taxable earnings used for withholding
• multiple jobs, where the tax-free threshold should generally only be claimed from one payer

Tax file numbers, residency, and study loan debts

Three inputs drive most of the calculation: the employee’s TFN details, their tax residency, and any study or training support loan. Errors here flow through every pay run until someone catches them.

Employees still complete a TFN declaration at commencement, either on paper (NAT 3092) or through their employee tax details summary from ATO online services. Under STP Phase 2, employers no longer send the declaration to the ATO (the tax treatment code reported through STP covers that), but you must keep it on file. If an employee has applied for a TFN but not yet received one, you withhold at standard rates for 28 days. If no TFN is provided after that, you must withhold at the top marginal rate plus Medicare levy.

Residency is a tax concept, not a visa concept. Australian residents for tax purposes can access the tax-free threshold; foreign residents are generally taxed from the first dollar at non-resident rates. Where the position is unclear, confirm before finalising payroll settings.

What to collect from new employees

A complete onboarding file supports correct withholding, super, and STP reporting from day one. For each new employee, collect and securely store:

• full legal name, address, date of birth, and contact details
• TFN declaration (paper or electronic via ATO online services)
• commencement date and employment basis (full-time, part-time, casual, or fixed-term)
• pay rate, award or agreement classification, and any loadings or allowances
• superannuation fund details, including stapled fund information where the employee has not chosen a fund
• bank account details for wages
• letter of offer or employment agreement
• Fair Work Information Statement, and Casual Employment Information Statement where relevant
• evidence of work rights where applicable
• any salary sacrifice agreement or authorised deductions

Withholding declarations (separate from the TFN declaration) should be collected when an existing employee’s circumstances change, such as starting or repaying a study loan or switching between resident and foreign-resident status.

What happens if an employee does not provide a TFN

If an employee has not provided a TFN, you must generally withhold at the top marginal rate plus Medicare levy. That can significantly reduce their take-home pay, so it is worth explaining the consequence at onboarding to encourage them to act. Where the employee has applied for a TFN, you can withhold at standard rates for 28 days while they wait for it to be issued. After 28 days without a TFN, the top rate applies until they provide one.

Document everything: what the employee told you, when they applied, and when the TFN is eventually provided. Update payroll promptly once the TFN is received, so the correct tax treatment applies from the next pay run.

How and when to pay PAYG withholding to the ATO

Your payment cycle depends on your total annual withholding across all branches of the business. The ATO reviews this each year and writes to employers in April if their cycle changes from 1 July.

Small, medium, and large withholder cycles

• Small withholders (annual withholding $25,000 or less) report and pay quarterly through their BAS.
• Medium withholders (annual withholding between $25,001 and $1 million) notify and pay monthly.
• Large withholders (annual withholding more than $1 million) pay electronically within six to eight days of each withholding event (for example, each pay run), using a unique Payment Reference Number issued by the ATO.

If your business grows, your cycle can change. A labour hire business that wins a major contract, or a hospitality venue that expands into a second site, can move from small to medium withholder quickly. Review your total withholding regularly rather than relying on the ATO’s annual letter to catch up.

How employers actually pay the ATO

For most small and medium businesses, the process is: reconcile payroll at the end of the period, lodge the BAS or IAS showing the withholding amount at label W2 (with gross wages at W1), then pay by the due date using BPAY, EFT, or another ATO-approved channel with the correct payment reference number.

STP reports tell the ATO what has been withheld, but they do not pay the ATO. Some business owners assume the two are connected. They are not. Reporting and payment are separate steps, and missing the payment step is where most PAYG withholding debt builds up.

A practical habit that works: transfer the withholding amount (and ideally the super liability) to a separate holding account after each pay run. Treat that balance as untouchable. It removes the temptation to dip into it when a supplier invoice or quiet trading week creates cash flow pressure.

Single Touch Payroll and PAYG withholding reporting

STP is how employers report payroll information to the ATO. Every pay run, STP-enabled software sends salary and wage details, PAYG withholding, and super liability information to the ATO. STP Phase 2, mandatory since 1 January 2022 for most employers, expanded the data reported to include disaggregated income types, employment basis, cessation reasons, and tax treatment codes. That removes the need to send TFN declarations or employment separation certificates separately, but it puts more weight on correct payroll setup.

How STP changes year-round reporting

Before STP, payroll reporting was largely an end-of-year task (payment summaries, annual reports). Under STP, reporting happens every pay cycle. That gives the ATO and employees near real-time visibility through myGov, but it also means errors hit the ATO record immediately. Misclassified allowances, missed HELP debts, or wrong pay categories can compound across multiple pay runs before anyone notices.

Strong payroll governance now includes:

• confirming employee setup, TFN details, and tax treatment when staff start
• reviewing award rates, allowance categories, and salary sacrifice arrangements
• reconciling payroll reports to the general ledger after each pay run
• correcting errors promptly, not saving them for year-end
• checking W1 and W2 figures on the BAS match STP totals before lodging

End-of-financial-year finalisation

STP did not remove the year-end finalisation step. By 14 July (for most employers) or by the relevant concessional date for closely held payees, you must make a finalisation declaration confirming your STP data is complete. Until you finalise, employees see their income statements in myGov marked as “tax ready pending employer finalisation”, which can delay their own tax returns.

Before finalising, reconcile gross wages, PAYG withholding, allowances, reportable fringe benefits, reportable super, termination payments, and any adjustments made during the year. Finalising early, before the reconciliation is complete, is one of the most common ways employers end up amending STP reports after staff have already lodged their returns.

Common PAYG withholding mistakes to avoid

Misclassifying workers and using the wrong tax table

Treating an employee as a contractor is the classic error. If the arrangement is really employment, you have missed PAYG withholding and, almost always, super guarantee. The label in the contract is not decisive. Factors such as control, delegation, provision of tools, commercial risk, and how the person is paid all count. High-risk sectors include construction, hospitality, cleaning, transport, and personal services.

Tax table errors are the next most common problem. Common traps include applying the tax-free threshold by default, missing a study loan notation, using resident rates for a foreign resident, and treating a bonus as ordinary wages. Review payroll setup whenever a worker starts, changes role, or receives an unusual payment type.

Missing deadlines, poor records, and underpayments

Most withholding problems come from routine failures: delayed bookkeeping, skipped reconciliations, BAS lodged late, withholding funds absorbed into operating cash during a tight trading month. These are preventable with simple controls.

Payroll records must show gross wages, tax withheld, superannuation, allowances, leave, and payment dates clearly. Incomplete records make BAS preparation harder, complicate STP finalisation, and weaken the business’s position if the ATO reviews payroll. Underpayments of either tax or wages usually require back-calculations, amended STP reports, communication with affected employees, and in some cases top-up payments plus interest.

Reconcile payroll to activity statements, STP data, bank payments, and general ledger balances at least quarterly. Set calendar reminders well ahead of BAS, IAS, and super due dates. If an error is identified, fix it now rather than waiting until year-end.

PAYG withholding for small businesses in Ipswich and South East Queensland

Small businesses around Ipswich, from Springfield through to the CBD and the wider South East Queensland corridor, often run lean on admin. Payroll gets squeezed between operational priorities, and that is where small compliance slips turn into expensive problems. A few habits keep things on track:

• quarantine withheld tax and super in a separate account after each pay run
• use STP Phase 2-enabled payroll software with correctly configured awards, allowances, and tax treatment codes
• confirm worker classification before the first payment, not after six months of invoices
• match your payroll cycle to your cash flow reality where the award allows
• build PAYG withholding and super into weekly cash flow forecasts, not just monthly P&L
• reconcile payroll after every pay run; check W1 and W2 on the BAS against STP before lodging
• act on ATO correspondence immediately, before interest and penalties escalate

Queensland employers should also watch the payroll tax threshold separately. Queensland payroll tax applies once annual Australian taxable wages exceed $1.3 million, or your proportional share if you employ across states. It is administered by the Queensland Revenue Office, not the ATO, and is separate from PAYG withholding. A regional employer discount of 1% applies in certain parts of Queensland until 30 June 2030, though Ipswich sits within the Greater Brisbane area and is generally not eligible for the regional rate. Grouping rules can pull related entities together for threshold purposes, so multi-entity structures warrant a careful look.

Frequently asked questions

What is the difference between PAYG withholding and payroll tax?

PAYG withholding is a federal obligation administered by the ATO. It is tax withheld from payments to employees (and certain contractors) and remitted to the ATO on the employer’s withholding cycle. Payroll tax is a state tax paid by the employer on its own wage bill once the state threshold is crossed. In Queensland, the threshold is $1.3 million in annual Australian taxable wages, with rates of 4.75% (up to $6.5 million in Australian taxable wages) and 4.95% above that, administered by the Queensland Revenue Office. A business can have PAYG withholding obligations from its first employee but no payroll tax liability for years.

Can an employer claim PAYG withholding back?

Not in the way the question is usually meant. PAYG withholding is not an employer tax; it is tax deducted from the employee’s entitlement and paid to the ATO on their behalf. The employer claims a deduction for the gross wage (subject to the normal deductibility rules), not for the withheld amount separately. Where an employer over-reports withholding on a BAS, duplicates a remittance, or misclassifies a payment, they can correct the reporting and recover the excess. That is a correction, not a claim.

When does PAYG withholding need to be paid?

Small withholders pay quarterly with their BAS. Medium withholders pay monthly. Large withholders pay within six to eight days of each withholding event. Your BAS or activity statement will show the due date for your cycle.

Do I still need TFN declaration forms under STP Phase 2?

Yes, you still need to collect TFN details from new employees (paper NAT 3092 or the electronic equivalent via ATO online services), and you must keep them on file. Under STP Phase 2 you do not need to send them to the ATO separately; the tax treatment code reported through STP carries the relevant information.

Getting advice for your business

PAYG withholding sits at the intersection of payroll, tax, super, and cash flow. If your business is hiring, growing, restructuring, or unsure whether a payment should have tax withheld, the cheapest advice is the advice you get before the first payment, not after the ATO writes to you.
