FOR WHOM IS THIS E-BOOK?
Anyone running an online business who has been told a limited company will save them tax, and would like to see the arithmetic before deciding.

Sole traders wondering whether to incorporate
The old rule said to go limited once you passed about thirty thousand. This book runs that exact number and finds the sole trader ahead by over a thousand pounds.

Company owners who have not looked since
If you incorporated on advice that was correct at the time, six rate changes have happened since, every one of them against you. It is worth checking whether the reason still holds.

Sellers reinvesting in stock
This is where a company still wins decisively. Chapter seven shows a deferral of over eighteen thousand pounds at the highest profit level, and explains exactly what it is worth.
FACTS
What each actually costs
Full comparisons at three profit levels, showing every line: corporation tax, employer National Insurance, dividend tax and the personal allowance taper. Nothing rounded, nothing assumed.
