How National Minimum Wage Increases Can Reduce Take-Home Pay for Some Umbrella Workers
Rising National Minimum Wage (NMW) rates are often seen as a positive move for low-paid workers. But for some contractors working through umbrella companies — particularly those using specific pay models that include tax-efficient components — an increase in NMW can actually lead to reduced take-home pay. This is not due to any wrongdoing, but rather a structural consequence of how certain umbrella arrangements are designed.
The Structure Behind Some Umbrella Pay Models
Umbrella companies act as employers for contractors, handling payroll, tax deductions, and compliance. The majority of umbrella companies use a standard PAYE model, where all earnings are taxed in full at source.
However, some umbrella companies offer alternative models that include a mix of a base salary and a secondary payment component. This second portion may be made up of tax-advantaged mechanisms, depending on the contractor’s circumstances and the umbrella’s structure. These arrangements are designed to optimise net pay while remaining within legal frameworks.
In such models, a contractor’s total income is generally divided into:
- A salary component, which must meet at least the National Minimum Wage and is fully taxed under PAYE rules.
- A secondary portion, made up of legal tax efficient arrangements based on the contractor’s situation.
The Impact of NMW Increases
When the government raises the National Minimum Wage, umbrella companies must increase the PAYE salary to stay compliant. Since this part of the income is taxed at source, a larger share of the contractor’s total income is now subject to full PAYE tax and National Insurance.
This leaves less available to be allocated through the secondary, tax-advantaged component. Although the gross salary increases (because it’s based on hours worked at the new NMW rate), a larger portion of the worker’s total contract income is now subject to full PAYE tax and National Insurance. This shift reduces the scope for any remaining tax-efficient arrangements, which can ultimately lead to a decrease in take-home pay.
To put it simply:
Higher NMW → higher gross salary → more tax/NICs → smaller tax-efficient portion → lower take-home.
Not All Umbrellas Are the Same
It’s important to stress that not all umbrella companies use this kind of pay model. Many operate on a simple PAYE-only basis, where all income is taxed in full, and NMW increases have no bearing on how earnings are structured. The scenario above applies specifically to arrangements where income is split between salary and compliant tax-advantaged elements.
Final Thoughts
Contractors using umbrella companies should ensure they fully understand how their income is structured — especially when working with models that include non-salary elements. While NMW increases are aimed at improving income levels, in certain umbrella setups they can unintentionally reduce take-home pay due to a shift in how the income is allocated and taxed.

If you're unsure how changes to NMW might affect your earnings, it’s worth asking your umbrella provider for a breakdown to understand your full pay structure.
