Payroll taxes

Payroll taxes affect many employment-related decisions

The range of tax rules and options available to employers continues to expand and become more complex. Examples include the work-related costs scheme, mobility budgets, flexible benefits schemes, expense allowances, the engagement of self-employed professionals and social security.

These rules are often interconnected. For example, the tax treatment of an allowance may affect payroll taxes. The way in which someone works for your organisation also determines whether that person is treated as an employee or as self-employed for tax purposes. An incorrect assessment can lead to corrections, additional tax assessments or penalties at a later stage.

A well-structured tax approach can help you control costs while offering employees suitable benefits. That is why we look not only at the tax rules themselves, but also at how arrangements are implemented in payroll and across your organisation.

Reviewing payroll taxes and payroll processing

OneLane assesses how payroll taxes are structured and applied within your organisation. We review areas such as employee benefits, pay components, allowances, mobility arrangements and specific forms of remuneration. We also check whether these arrangements are processed correctly through payroll.

Our specialists can carry out a payroll tax and salary review. This identifies potential tax risks and areas for improvement. We examine, for example, the work-related costs scheme, expense allowances, social security, specific employer levies and the tax treatment of particular employee situations.

This gives you an independent review of your current set-up, together with practical recommendations on what could or should be changed.

Advice on audits and complex tax matters

OneLane can also assist you during payroll tax audits, discussions with the Dutch Tax and Customs Administration (Belastingdienst) or complex tax matters. We explain what the rules mean for your situation and help you adjust agreements and processes where necessary.

This may include questions about engaging self-employed professionals, false self-employment, mobility arrangements or specific forms of remuneration. We look not only at what has been agreed on paper, but also at how the working relationship operates in practice.

This gives you a clear picture of where tax risks may arise, which changes may be needed and where there is scope to structure employee benefits and allowances differently.
