No we don't pay corporation tax.
Our companies do - we pay taxes only based on our personal income.
This is what always surprises me with people who own companies, and who then moan when they have literally not got a pot to p*ss in.
The way I look at it, and always have, is that I have always (and I have owned 7 companies in the last 20+ years) tried to save as much tax, or 'government take' as humanly possible. It has served me well.
Anything saved, is money that would have been going to director funds. Compared to just being 'self-employed' the old feeling was that we get away with lower salary and bumped up with dividends because we pay corporation tax on the same money we bring in, where a SE would not pay that.
I have had companies with almost a million in VAT/Corp-tax-paid shareholder funds, and never once did I take more than allowed under the 20% tax bracket (I have never paid more than 20% tax). I simply exhausted them over the years with minimum tax.
I remember with the financial crash in 2007/2008, my accountant said: "well, you did the right thing, as most lived a champagne lifestyle, whilst you built up the pot".... I paid my mortgage off after three years the same year as the financial crash.
I became financially independent, and mortgage free by 36 years old using the same principles that have been called 'odd' and 'wrong' on this same thread.
The conclusion? You can be as self-righteous as you like when discussing business, but at the end of the day, it does not mean a great deal if you have not gained the benefit.
