What is the difference with self employed and self assessment when it comes to taxes?
It is not that there is any difference between them. They are complementary to one another. Usually when anybody is employed, their tax is worked out and paid through PAYE. For the self-employed, their tax bill is calculated after they complete a Tax Return, which is send out every April 6th. That is self-assessment. Sometimes, in certain circumstances, employed people have to do it too, but that is rare, and it means either they have extra or specialised income. People get the same personal allowance, however they are taxed, but the self-employed can usually claim more in the way of expenses.
