How Bonuses Can Push Income Above £100k
Bonuses form an important part of compensation for many professionals in the UK, particularly in sectors such as finance, consulting and technology.
While bonuses can increase overall income, they may also push total earnings above key tax thresholds.
One important threshold is £100,000 of adjusted net income, where the personal allowance begins to reduce.
Understanding how bonuses affect taxable income can help individuals anticipate potential tax changes.

How Bonuses Are Taxed
Bonuses are generally treated as employment income.
This means they are taxed through the PAYE system in the same way as salary.
Bonuses are typically subject to:
- Income tax
- National Insurance contributions
This means that a bonus can increase a person's total taxable income for the year.
Why the £100k Threshold Matters
Once income exceeds £100,000 of adjusted net income, the personal allowance begins to reduce.
The allowance reduces by £1 for every £2 of income above £100,000.
This means individuals with income in the £100k to £125k range can experience a significantly higher effective tax rate.
Our article on the £100k tax trap explained explores how the personal allowance withdrawal affects effective tax rates.
Understanding how adjusted net income is calculated is also important in this context. Our article on adjusted net income explained covers how this figure is determined.
Example: Bonus Impact
Consider someone earning a salary of £95,000.
If they receive a bonus of £10,000, their total income becomes £105,000.
This means:
- The personal allowance begins to reduce
- More income may be taxed at higher rates
In practice this can mean the tax impact of bonuses is greater than expected.
Note: This is a simplified illustration only. Individual tax calculations depend on personal circumstances and the full adjusted net income calculation.
Planning Around Bonus Income
While bonuses are often determined by employers, individuals may consider certain planning strategies.
These may include:
- Increasing pension contributions
- Using salary sacrifice arrangements
- Understanding how adjusted net income is calculated
Pension contributions may reduce adjusted net income, which can affect how tax thresholds apply. Our article on pension tax planning explained explains how pension contributions interact with tax relief and allowances.
Salary sacrifice arrangements can also help redirect pre-tax income into pension contributions. Our article on salary sacrifice explained covers how this type of arrangement works.
