Reaching an income of over £100,000 is a significant milestone, but it comes with important tax considerations that can affect how much of your earnings you actually take home. In the UK, higher earners face several unique tax implications, including the loss of certain allowances, the potential for a higher marginal tax rate, and additional complexities in tax planning.
1. Personal Allowance Reduction
One of the most significant tax implications for individuals earning over £100,000 is the gradual loss of the Personal Allowance. For the 2024/25 tax year, the standard Personal Allowance is £12,570. However, this allowance is reduced by £1 for every £2 of income over £100,000.
This means that by the time your income reaches £125,140, you will have lost your entire Personal Allowance, effectively resulting in an extra tax charge on this portion of your income. This creates an effective marginal tax rate of 60% for earnings between £100,000 and £125,140, as you pay 40% on the income itself and an additional 20% due to the loss of the allowance.
2. Higher Rate Tax Bands
The UK has a progressive tax system, meaning that as your income increases, so does the percentage of tax you pay on your income over certain thresholds. For the 2024/25 tax year, the tax bands are as follows:
Basic Rate (20%): Income between £12,571 and £50,270
Higher Rate (40%): Income between £50,271 and £125,140
Additional Rate (45%): Income over £125,140
For those earning over £100,000, the majority of your income will likely fall into the Higher Rate tax band, and any income over £125,140 will be taxed at the Additional Rate of 45%.
3. Child Benefit Tax Charge
If you or your partner earn over £50,000 and receive Child Benefit, you may be subject to the High-Income Child Benefit Charge (HICBC). This charge effectively claws back the Child Benefit through additional tax, at a rate of 1% for every £100 of income over £50,000. Once your income exceeds £60,000, the entire benefit is effectively wiped out.
For those earning over £100,000, this charge can add a substantial amount to your tax bill if you have been claiming Child Benefit.
4. Pension Contributions and Tax Planning
One way to mitigate the loss of your Personal Allowance and reduce your overall tax liability is through pension contributions. Pension contributions are deducted from your income before tax is calculated, which can effectively lower your taxable income. For example, if your income is £110,000 and you contribute £10,000 to a pension, your taxable income reduces to £100,000, potentially preserving your full Personal Allowance.
5. Additional Considerations
Beyond the direct tax implications, earning over £100,000 can have other financial impacts, such as:
National Insurance Contributions (NICs): While these do not increase directly due to crossing the £100,000 threshold, the higher your income, the more NICs you pay.
Student Loan Repayments: If you have a student loan, your repayments are based on a percentage of your income above a certain threshold. Earning over £100,000 will likely increase your monthly repayment amount.
Potential Impact on Financial Planning: With the increased tax burden, high earners should pay close attention to financial planning, including estate planning, tax-efficient investments, and charitable donations, which can help reduce overall tax liabilities.
Conclusion
Earning over £100,000 in the UK is undoubtedly a significant achievement, but it comes with complex tax implications that require careful planning. From the gradual loss of Personal Allowance to higher marginal tax rates and potential additional charges, understanding these implications is crucial for effective financial management. By leveraging strategies such as pension contributions and tax-efficient investments, high earners can mitigate some of the tax burdens and make the most of their income.
