- Check your tax code after any job or benefit change — millions are wrong each year
- Pension contributions near £60k/£100k thresholds carry outsized value
- Claim the small reliefs — Marriage Allowance, mileage, uniform, professional fees
- File by 31 January even if you can't pay — penalties punish silence, not poverty
The Details That Decide Outcomes
A few pounds of income can cost hundreds in reliefs: crossing £60,000 tapers Child Benefit; £100,000 withdraws the personal allowance at an effective 60% rate. A pension contribution that drops you below a threshold can have an effective return of 60%+.
Most tax savings are claims, not schemes: Marriage Allowance (up to £252/year, backdatable four years), uniform and mileage relief, professional-fee deductions — small individually, meaningful stacked.
Engagement beats avoidance with HMRC: Time to Pay arrangements spread bills over months with modest interest, while silence triggers automatic escalating penalties.
