Tax planning tips for London

The most impactful planning tool for UK employees is pension contributions. Contributions to a workplace or personal pension reduce your taxable income — a higher-rate taxpayer effectively pays only £60 to put £100 into their pension. If your salary is between £100,000 and £125,140, pension contributions are especially valuable because each £1 contributed reduces your 'adjusted net income', preventing the Personal Allowance from being withdrawn and avoiding the effective 60% marginal rate in this band. The ISA allowance (£20,000/year) provides a tax-free wrapper for investments and savings.

Common mistakes to avoid

The most common mistake UK employees make is not claiming higher-rate pension tax relief through self-assessment. If you are a 40% taxpayer making pension contributions, your employer's payroll captures only 20% basic rate relief automatically — you must claim the additional 20% via a tax return. Another common error is failing to account for the National Insurance cliff at £50,270, where the combined marginal rate drops from 28% (20% IT + 8% NICs) to 42% (40% IT + 2% NICs) as you cross the higher rate threshold.
