Read This Before You Apply

Most tax savings are claims, not schemes: Marriage Allowance (up to £252/year, backdatable four years), uniform and mileage relief, working-from-home relief where eligible — small individually, meaningful stacked.

A few pounds of income can cost hundreds in reliefs: the £60k and £100k thresholds carry hidden marginal rates. A pension contribution that drops you below a threshold can have an effective return of 60%+.

HMRC is more flexible before the deadline than after: Time to Pay arrangements are routinely granted online for bills under £30,000, whereas ignored deadlines compound at £10/day after three months.
