Learn how UK tax really works
Understanding how your own tax works is worth real money, and almost nobody explains it plainly.
The rules are not simple. There are hidden high-tax bands, cliffs that cost thousands of pounds at a single pound of extra income, and reliefs most people never claim. I have taken the time to pick the system apart, check every figure against HMRC, and write it down clearly. These guides are the result, and each one earns its place. If a page would not genuinely help you understand or act, it is not here.
Is there a part of your own tax you want explained that is not here yet? Ask me to write a guide.
- The £100,000 tax trap
Why your marginal rate hits about 62% between £100,000 and £125,140, the childcare cliff that makes it worse, and how to climb out.
- The Child Benefit tax charge
Child Benefit itself is not taxed, but a separate charge claws it back between £60,000 and £80,000. Here is how it works, and how a pension keeps it.
- How Scottish Income Tax differs
Six rates instead of three, a 42% band that starts at £43,662, and where the difference actually costs you money.
- How a pension contribution cuts your tax
How much tax a contribution saves, the three ways to make one, and why salary sacrifice beats the rest by cutting your National Insurance too.
- The pension Annual Allowance
What the £60,000 limit really means, why going over does not always cost you, and the taper that shrinks it for high earners.
- Tax codes explained
What the numbers and letters mean, what changes your code, and why paying off a student loan does not.
- How Gift Aid cuts your tax
How the basic-rate top-up works, the higher-rate relief you claim yourself, and how a donation can rescue your £100,000 Personal Allowance.
- How salary sacrifice cuts your tax
How giving up gross pay before tax and National Insurance makes a pension, a car or a bike cost you less, and the wage floor that limits it.
