As we head into the final months of 2025, HR and payroll leaders are turning their attention to one of the most critical tasks on their horizon: budgeting for 2026. With rising employment costs, increasing regulatory complexity, and ongoing pressure to modernise, building a well-thought-out HR and payroll budget is no longer just about forecasting headcount or estimating merit increases. It’s about creating a flexible, strategic roadmap that aligns with business goals, anticipates change, and enables agility.
The Economic and Regulatory Landscape
Economic growth remains sluggish across the UK and much of Europe, with the British Chambers of Commerce forecasting just 0.9% GDP growth for the UK in 2025. That modest growth is being offset by rising payroll-related costs, including a potential National Insurance increase to 15%, a burden that will hit employers hard in 2026.
This broader context means HR and finance leaders must prepare for increased scrutiny of salary budgets, compliance obligations, and the total cost of employment. A “set it and forget it” mindset won’t cut it. Strategic scenario planning is essential.
Salary growth is stabilising, but costs are not
Data from compensation benchmarking firms suggests salary increases are beginning to level off. Payscale’s most recent Salary Budget Survey shows that organisations are planning average base pay increases of 3.5% in 2026, slightly down from previous years. Similarly, Mercer forecasts merit increases of around 3.3%, while promotions account for roughly 9-10% of workforce costs with an average raise of 9.3%.
But flattening pay increases don’t mean payroll teams can relax. Instead, they must plan for steady, but still significant, growth in salary budgets, while also carving out capacity for off-cycle adjustments, promotions, and cost-of-living updates.
As specialists in payroll transformation and technology consulting, we have seen first-hand how rigid pay strategies limit organisations’ ability to retain top talent. “HR and payroll leaders need to budget not just for what they know, but for what they can’t predict,” says Cintriq founder Bob Rehill. “It’s about building in flexibility, whether that’s to react to market pay shifts or regulatory changes.”
Rethinking workforce assumptions
Recent surveys show that the majority of organisations are not planning significant headcount changes in 2026, with around 76% holding steady and only 14% expecting growth. However, with minimum wage increases, employer tax hikes, and pensions reform on the horizon, the cost per employee is set to rise.
Rather than focusing purely on the number of hires, HR budgets need to reflect the quality of spend. That means distinguishing between essential and discretionary roles, accounting for retention and reskilling strategies, and considering workforce mix (full-time vs. contractor vs. outsourced services).
Technology: From cost centre to strategic enabler
A key trend shaping 2026 budgets is investment in payroll and HR technology. The days of seeing tech upgrades as optional are over. According to recent reports, nearly half of HR leaders are allocating between £100k and £500k per year to systems upgrades, particularly in payroll integration, automation, and analytics tools.
Smart HR teams are earmarking at least 10-15% of their total budget for digital modernisation in 2026. Cintriq’s work with enterprise clients often centres on this transformation. By automating repetitive tasks, improving data integrity, and enabling real-time insights, payroll technology isn’t just a cost, it’s a catalyst for better governance and agility.
Building in flexibility and scenario planning
Ultimately, the most effective HR and payroll budgets for 2026 will be those that are adaptable. That means creating multiple budget models – conservative, moderate, and growth-focused, based on headcount plans, tax scenarios, and inflation forecasts. It also means setting aside contingency funds (typically 5-7% of budget) to account for unforeseen changes in legislation or market dynamics.
Good governance is critical too. Budgets should be created collaboratively between HR, finance, and operational leaders, with KPIs in place to track the return on salary, benefits, and technology spend.
Conclusion: Strategy, not spreadsheets
Budgeting in HR and payroll used to be an annual administrative task. Now, it’s a strategic function, one that can unlock organisational resilience, compliance, and employee satisfaction.
By anchoring your 2026 planning in data, tech investment, and flexible frameworks, you can position HR not just as a cost centre, but as a business enabler in the year ahead.
