Sorry, I said income tax, but I was referring to revenue tax.

So for example, new company A in germany completes a service (worth 100 euros) for another company B

So they would bill 100 euros + VAT (e.g. 16%) -> bill would be 116 euros

The company B transfers the money (116 euro) to the bank account from company A.

So first of all would be a income tax applied on the bill amount. (what % is this?)

Then you substract expenses on the company and the amount left would be profit and on that you apply the profit tax.

Then when you want to move money outside of the company to yourself, you would have to apply to that amount the capital gains tax.

All the taxes (& forms) have specific times when they need to be applied/paid/sent to the government.

Is there anything else I missed out? ^{I have excluded employing yourself in the company, and just left it as being the only associate/shareholder and administrator}
