Tax and banking
The tax number, the books and the corporate bank account are three separate results. Opening the company does not open the account.
The tax number is its own step
The trade registry extract shows that the company was recorded. The tax number is issued by the tax office after that. Banks, invoices and withholding all ask for it. Treating the registry receipt as a tax number delays the first invoice.
Books and the monthly calendar
A Turkish company keeps statutory books. A bookkeeper files the returns the activity triggers. Value-added tax, withholding and advance corporate tax do not apply in one identical pattern to every company. The proposal says which filings your activity creates. It does not quote a tax rate as if it were permanent.
What the bank asks for
A corporate account is a decision by the bank. The usual file includes the registry extract, the tax number, the signature circular, the owners, and the source of funds. Foreign owners add identity documents and, where the bank asks, proof of address. Some banks decline a given sector or a given ownership pattern. We assemble what they ask for. The refusal, if it comes, is the bank’s.
Founders who are not in Turkey
Shareholders can complete much of the tax and bank file through documents and a local representative. Someone still has to be able to sign as the bank requires. Who that is depends on the signature circular, not on a general rule printed here. Foreign founders covers ownership and presence. The formation steps show where the tax number sits in the chain.
