If I got it, the main tax an UK Ltd has to pay is the corporate tax, which is about 20% of the total income of the company. This income include income derived from bonds, stocks, mutual funds distributions of coupons and real estate rents.
So, let's suppose my Ltd company owns $1M of Coca-cola stocks, which produces a yield of 3%, my Ltd will earn 30.000$ per year, and will pay $6000 as corporate tax, having a net income of $24.000. This will be the same also for bonds, ETF funds and so on, right?
What about operating expenses of the company, for example paying rent for its HQ, or buying equipment such as a laptop? Shouldn't that be subtracted before calculating the corporate tax?
For example: if those Coca-cola shares make my company to income a gross of $30.000, and I pay the rent of company's HQ which is $10.000 and a laptop which costs $1000, I will have a net income of 30.000 - (10.000 + 1.000) = $19.000. And then, I'll pay corporate tax on that net income of $19.000 which will be $3800. Resulting in a total net income of $15.200.
Or, these operating expense are taxed just after calculation of corporate tax?
What about if the Ltd company rents a real estate it owns? I guess that repairs and maintenance of those real estates could be paid before corporate tax, because are mostly operating expenses.
And, what about VAT? Does a Ltd company have to pay VAT on the rent income it receives?
For example, if the Ltd lets a building which produces £50.000 of gross income, if it should pay both VAT and corporate tax on that, would net only £32.000 instead of £40.000 of corporate tax only, without VAT.
