30% of what I make each week goes straight into an account. Should get a savings account really, but at the moment I just have a Basic account for that. Oh well....
It's Simple :
If you have set money aside : no problem. You will probably even have money left after deductions.
If you have Not set money aside : Big problem. You will have a very hard time getting the money. Where are you getting that money from all of the sudden?
So don't be stupid, set money aside each week. If you don't, well, you get the idea. I didn't do it in the beginning, and had to put almost everything I earned for a couple of weeks in that account. Horrible.
It's very easy with George, in the right pane of the main menu, see what you made each week, divide by 100, multiply by 30% (22% Income Tax, and 7% NI just to be on the safe side : ~30%) Yes it will probably be less then that total amount every year, but at least you don't have to worry ey?!!
Get Internet Banking, and just transfer the funds from your business/current account into your Tax/NI account. Easy.
