It's 10pm. You've just remembered a payroll change that might not have happened. Tomorrow, payroll runs. The regulator is watching more closely than ever. Do you sleep – or open your laptop?
Most payroll and HR professionals will recognise that scenario. The stakes have always been high – payroll errors don't just cost money. They cost you sleepless nights, employee complaints, and uncomfortable conversations with the board about why the data doesn't add up.
But here's what's changed: the compliance landscape is shifting, and it's shifting fast. Structural changes to how government enforces employment law mean that HR and payroll teams are being asked to move faster, be more accurate, and prove it – with clean data. This isn't a failure of effort. HR/payroll compliance is just harder now.
The Fair Work Agency: a new HR payroll compliance reality
The Fair Work Agency (FWA) launched on 7 April 2026. Introduced under the Employment Rights Act 2025, it consolidates enforcement functions that were previously spread across multiple bodies into a single, powerful agency with a clear mandate: to improve compliance.
Its remit covers the minimum wage, statutory sick pay, average holiday pay, and agency worker legislation – but its powers go significantly further than previous enforcement frameworks. The FWA can:
- Conduct unannounced workplace visits
- Demand payroll and HR documentation
- Issue notices of underpayment
- Impose mandatory financial penalties
- Name and shame non-compliant businesses
- In serious cases, pursue criminal sanctions, including unlimited fines and imprisonment
Personal criminal liability has also been extended to company directors, managers, and shareholders where breaches occur through their direct consent, connivance, or neglect.
One of the most significant shifts is the move to strict liability enforcement. Previous regulatory interventions often allowed leeway for administrative mistakes. Under the FWA, that leeway is gone. Organisations are penalised for errors regardless of whether they were intentional. Ignorance was never an excuse – but now it won't even be excusable.
The agency also has unprecedented access to data. It has a statutory gateway to share and receive information from HMRC (RTI and Making Tax Digital), the Home Office, law enforcement, local government, workplace authorities, health and social care bodies, and even media sources. It will use machine learning and AI to monitor that data continuously – which means non-compliance is unlikely to stay hidden for long. Your data is already in their hands. They will know.
The FWA isn't just a new name for an existing function. It has targets, it has tools, and it has a mandate to ensure that the changes coming through the Employment Rights Act over the next 18 months are implemented correctly. Better guidance will be provided – but better compliance will be expected in return.
The real problem: it's not bad people, it's bad data joins
Most HR payroll compliance failures aren't caused by bad decisions. They're caused by bad joins – the gaps between systems where data gets lost, delayed, or entered twice by someone who knows the workaround.
Think about what happens in a typical week. Someone joins on Monday. HR knows. Payroll finds out on Friday – after the pay cycle has already run. Now you're chasing a manual adjustment and hoping the numbers reconcile. HR updates the holiday policy in their system. Payroll is still calculating based on the old rules. Nobody notices until an employee complains. An employee moves from part-time to full-time. The change effects pay, holiday accrual, and pension contributions – all compliance-sensitive. But does every system reflect it? And can you prove it?
There's often one person in the team who 'just knows' how to make the spreadsheet work. What happens when they're on holiday? Or when they leave? Single points of failure are a compliance risk – and so is the absence of an audit trail. If your data lives in spreadsheets, proving what happened, when, and who authorised it is close to impossible.
And the problem compounds in ways that aren't always visible. Disconnected systems don't just slow you down – they create silent compliance risks that only surface when it's too late. Without real-time integration, there's a lag between when something goes wrong and when you find out. By then, you're not managing a process. You're managing an incident.
It's worth making the human impact concrete. In a world of remote working, data gaps have real consequences that extend beyond payroll errors. Someone might know an employee is pregnant from a Teams call – but that data is critical for HR and payroll to ensure the right processes, safety checks, and payments are in place. Has the manager been informed? Has an interim been recruited? Have health and safety checks been completed? Has the leave date been agreed? Each of these questions represents a point where data needs to flow – and where, in disconnected systems, it often doesn't.
Integrated HR and payroll isn't just about software. It's about data communication – data that is shared cleanly and accurately across the people, processes, and systems that need it. It's about the culture that ensures that flow happens reliably, and the visibility that makes it auditable.
Practical HR payroll compliance steps: progress, not perfection
You don't need to rip everything up and start again. That's not realistic, and it's not necessary. What's needed is a deliberate approach to strengthening the joins between HR and payroll – starting with the areas of highest risk.
1. Map your highest-risk data touchpoints
Don't try to fix everything at once. Start with the three or four moments where data has to flow between HR and payroll, and where getting it wrong hurts most: starters, leavers, pay changes, and statutory pay calculations. These are the areas where the FWA is most likely to look first, and where errors are most likely to compound.
2. Identify where data is re-keyed or duplicated
Every time data is touched, it creates risk. Identify where the same data is being entered multiple times across systems – that's your first target for improvement. Every manual re-key is a compliance risk.
3. Prioritise auditability
The Fair Work Agency is coming, with the tools to interrogate your data in ways previous enforcement bodies couldn't. Can you prove what happened? Can you show what changed, when, and who authorised it? Start building that audit trail now – before you're asked for it.
4. Give both HR and payroll shared visibility
Integration isn't just about systems – it's about giving both teams sight of the same data. Who owns the data versus who reports on it can be a source of significant confusion. Connected analytics that draw from both HR and payroll create a joined-up picture that both teams can act on.
Why now: two things that have changed
The argument for better HR payroll compliance and data integration isn't new. What's new is the urgency – driven by two forces converging at the same time.
The FWA
With access to RTI data, Making Tax Digital data, and information from multiple government and regulatory bodies, the agency doesn't need to rely on employee complaints to find problems. It can – and will – use machine learning to monitor data continuously and act proactively. New requirements are also expanding what needs to be recorded: as of April 2026, employers must maintain holiday pay records for six years, including entitlements, balances, calculations, precise dates of holiday taken, and any carry-overs. Manual processes make this harder. Connected systems make it achievable.
AI
The HR and payroll teams who will get the most from AI are the ones whose data is already clean and connected. AI sentinels – agents running continuously to monitor and flag potential compliance issues – are only as useful as the data they can see. If half of your processes that move HR data into payroll are manual or rely on workarounds, AI can't help you. You'll make more errors, not fewer. But when your data is integrated and your systems talk to each other reliably, AI becomes genuinely powerful: the office assistant you always wanted, giving you more capacity and better compliance simultaneously.
From firefighting to resilience
The goal isn't to be compliant just enough to avoid a penalty. It's to build the kind of connected, visible, auditable data infrastructure that makes compliance a natural outcome of how your organisation works – not a panic that happens the night before payroll runs.
Connected data means one source of truth flowing between HR software, payroll software, and benefits systems. It means changes that happen in one place are reflected everywhere they need to be – without anyone re-keying them. Looking ahead to the mandation of Benefits in Kind payrolling, a single value moving cleanly around integrated systems will make reconciliation significantly easier.
Shared visibility means both HR and payroll teams seeing the same picture and owning the same outcomes. It means the data isn't siloed by team or system – it's a shared resource that both functions can act on and be accountable for.
And systems that work with you – not against you – means processes and tools that support the people doing the work, rather than the other way around. Fighting the system doesn't work. The system should be doing the heavy lifting.
HR payroll compliance: the bottom line
You don't need to rip everything up and start again. But you do need to stop accepting the gaps between your systems as normal. Because the Fair Work Agency won't.
From firefighting to resilience: that's the journey. And it starts with the next payroll run.
