Key takeaways on Single Touch Payroll (STP)

  • Global alignment: STP is Australia's version of the UK's RTI system, requiring real-time digital reporting to the tax office every time you pay employees.
  • Expansion readiness: UK firms hiring in Australia must comply with STP Phase 2, reporting income and superannuation liabilities to the ATO on or before payday.
  • UK 2025 reforms: UK employers face rising costs, with National Insurance up to 15% and the Secondary Threshold dropped to £5,000.
  • Digital compliance: Both STP and RTI demand cloud-based software to automate data transmission and ensure accurate tax withholding.
  • Future outlook: 2026 digitalisation and employment reforms make manual payroll processing increasingly high-risk for growing businesses.

Single Touch Payroll (STP) is the Australian standard for real-time tax and superannuation reporting, almost identical to the Real Time Information (RTI) system familiar to HR and finance teams across the United Kingdom.

What is the meaning of Single Touch Payroll?

Single Touch Payroll (STP) is an Australian government initiative to streamline business reporting obligations.

It requires employers to report payments such as salaries, wages, tax withheld and superannuation (covering pensions savings) to the Australian Taxation Office (ATO) at the same time they pay their employees.

How is STP similar to the UK system?

STP is reassuringly familiar to UK finance managers because it mirrors the Real Time Information (RTI) system used by HMRC.

Just as you send a Full Payment Submission (FPS) every pay run, STP-enabled software sends similar data to the ATO in one unified submission.

This ‘single touch’ ensures that the tax office has up-to-date information on a business’s tax and superannuation obligations, and each employee’s year-to-date income throughout the financial year.

How does STP work for international operators?

International operators expanding to Australia must use software that is specifically ready for STP Phase 2 reporting, as standard UK setups will not work.

When you process your payroll, the solution will automatically send the required data to the ATO. This eliminates the need to provide payment summaries to employees at the end of the financial year, as the information is available to them online via their myGov account.

How does STP compare to UK Real Time Information?

While the acronyms differ, the mechanism is largely the same. Both systems were introduced to modernise the tax system, and ensure that data regarding income tax and social security (National Insurance or superannuation) is captured in real time.

Feature Single Touch Payroll (Australia) Real Time Information (UK)
Regulator Australian Taxation Office (ATO) HM Revenue & Customs (HMRC)
Submission timing On or before payment date On or before payment date
Key contributions PAYG Withholding & Superannuation PAYE & National Insurance
Employee portal myGov Personal tax account
Year-end process Finalisation declaration by 14th July Final FPS by 19th April

UK businesses accustomed to the rigour of RTI will find the transition to STP relatively smooth, provided they have the right digital infrastructure. However, specific rules around superannuation (‘super’) liability and payment deadlines differ significantly from UK pension regulations.

What is the current UK payroll landscape in 2026?

The key reforms introduced, in April 2025, for the 2025/26 tax year involve significant shifts in National Insurance rates and thresholds that impact your budget. While understanding STP is vital for global operations, domestic compliance remains the priority for UK-based HR and finance teams.

How have National Insurance and wages changed?

In April 2025, the cost of employing staff in the UK rose significantly due to an increase in the Employer National Insurance rate (NICs) to 15%.

Simultaneously, the Secondary Threshold, at which employers start paying NICs on an employee’s salary, was reduced from £9,100 to £5,000 per year, and is expected to be frozen at this level until April 2031.

These changes, alongside that concerning the National Living Wage, which is projected to rise to £12.71 per hour in April 2026, mean that accurate data and forecasting enabled by automated payroll software are more essential than ever.

What new statutory rights have been introduced?

The Employment Rights Act 2025 (formerly ‘Bill’) has now received Royal Assent, legally confirming the introduction of day-one rights for paternity, unpaid parental, and bereavement leave in the upcoming 2026/27 tax year.

Furthermore, the Neonatal Care (Leave and Pay) Act, introduced in April 2025, has strengthened leave entitlements by providing up to 12 weeks of additional paid leave for parents whose babies require neonatal care. HR and finance managers must ensure their systems are tracking these new leave types accurately to ensure full compliance.

What changes are expected in April 2026?

As we look ahead to the new tax year in April 2026, reforms focus heavily on expanding worker rights, adjusting the National Living Wage, and further digitising tax reporting. Finance and HR directors should be finalising their systems now to handle these upcoming shifts.

How will the National Living Wage rise?

Following the Low Pay Commission’s recommendations, the National Living Wage is projected to rise to £12.71 per hour in April 2026. This increase aims to keep wages aligned with the cost of living, but will add further pressure to payroll budgets already strained by the NI reforms.

How will employment rights expand?

The Employment Rights Act is set to implement major changes by April 2026, including making Statutory Sick Pay (SSP) available from the first day of illness, by removing ‘waiting days’.

Additionally, rights to paternity and unpaid parental leave are expected to become ‘day one’ rights, meaning your software must be ready to track eligibility from an employee’s very first day of employment.

What is the future of digital tax reporting?

Making Tax Digital (MTD) for Income Tax Self Assessment (ITSA) becomes mandatory in April 2026 for landlords and self-employed individuals earning over £50,000.

While this primarily affects sole traders, it signals a broader move by HMRC towards total digitalisation, reinforcing the need for a flexible, integrated HR, payroll and finance platform.

Why is cloud software essential for compliance and efficiency?

Cloud software is essential because the ATO and HMRC both rely on digital data streams that manual spreadsheets cannot reliably provide.

Whether you are dealing with STP in Australia or RTI in the UK, modern platforms are required to handle the real-time data transmission.

How can software reduce administrative burden?

Using compliant solutions reduces administrative burden by allowing you to run your monthly process in minutes rather than days.

For example, good payroll software will automate the calculation of tax, National Insurance, and pension contributions, ensuring you send the correct information to HMRC without any manual intervention at all. This level of automation is crucial when dealing with complex reforms like the 2025 NI changes.

How does integration improve financial visibility?

Modern payroll solutions do not exist in a silo, but will connect directly with your accounting software. This integration works by automatically mapping payroll components, such as net pay, tax, and pension liabilities, to your general ledger codes, ensuring that every penny is accurately recorded without manual data entry errors.

Workflow step Traditional manual process Integrated cloud solution
Data entry Manual input into spreadsheets Automated sync from HR data
Calculations Formula-based, prone to error Real-time, legislatively updated
Reporting Manual upload to a portal Auto-submission via API
General ledger Manual journal creation Instant sync to accounting

How does technology enhance the employee experience?

Technology enhances the employee experience by providing the transparency that modern workforces expect. Under STP, Australian employees can check their super and tax info online.

Similarly, UK staff can benefit from electronic payslips and online portals, where they can view all of their documents and manage their leave. This self-service approach reduces the admin load on your office resources, and builds trust with your workforce.

Frequently Asked Questions (FAQ) about Single Touch Payroll

Under STP, you must report to the ATO on or before the day you pay your employees. In the UK, the RTI rule is identical: you must submit your Full Payment Submission (FPS) to HMRC on or before the payment date. Ensuring your finance team has read into the specific submission cut-off times for BACS payments is also vital, in order to ensure you do not miss the window.

Yes, STP reporting is mandatory for all Australian employers, regardless of the number of employees. Similarly, UK RTI applies to almost every employer, from small startups to large enterprises, with rare exemptions only for care support employers, religious objectors, or the digitally excluded. Small businesses in the UK must ensure they are compliant to avoid penalties, as exemptions are now virtually non-existent for active trading companies.

If you report incorrect data, both the ATO and HMRC allow for corrections. In STP, you can fix mistakes in your next report (an update event). In the UK, you can correct errors in your next FPS, or via an Employer Payment Summary (EPS).Often, mistakes happen when teams haven’t read up on specific data formatting requirements, so having expert support available can help you resolve these issues quickly.

No, but they serve a similar purpose. Superannuation (‘super’) is a mandatory contribution employers must make to an Australian employee’s fund, currently 12% (with ‘Payday Super’ payment reforms expected in July 2026). This is distinct from UK auto-enrolment pensions. If you help manage a global team, you will need to ensure your services provider understands these jurisdictional differences in order to avoid unexpected liabilities.

Yes, you cannot submit STP or RTI reports manually via email or paper. You need enabled and compliant software that connects directly to the respective government services. For UK operations, choosing a solution that is HMRC recognised is the first step to ensuring you are ready for the future. Once you have read the technical specifications, you will see that cloud-based automation is the only viable path forward.
