FAQ
- Why is my Scottish result different from an English one?
- Scotland sets its own bands: six of them in 2026/27, from 19% to 48%. Below roughly 30,000 you pay slightly less than in England; above the 43,663 higher-rate threshold you pay noticeably more.
- Does this include payments on account?
- No. This is the true tax on the year. How you pay it (balancing payment plus two payments on account) is cashflow, and our payments on account planner models that part.
- What happened to Class 2 National Insurance?
- Since April 2024 it is no longer charged. Above the small profits threshold you still get your state pension credits; below it, paying voluntarily can protect your record.
