Incorporating a company is a one-time step; the bookkeeping, VAT and withholding filings, e-invoice/e-ledger duties, and annual corporate tax return that follow require ongoing attention. This is handled through our partner accountants.

Setting up a company in Turkey can look like it ends with registration at the trade registry, but that is actually where the real financial responsibility begins. Within the first month, the company needs to have its statutory books notarised and start its accounting records, and it will generally need to file a VAT return on a monthly or quarterly basis. If the company has staff, a withholding and social security declaration is added to that; companies above a certain turnover threshold are also required to use e-invoicing and e-ledgers. All of this calls for a relationship that lasts far longer than the signing of the incorporation documents.
In practice, the most common problem is that this calendar of duties gets lost in the excitement of setting up. Delays are even easier when a company partner lives abroad: an invoice isn't issued on time, a return is forgotten, bank transactions get mixed up with the partner's current account. Our partner accountant steps in right after incorporation, sets up the bookkeeping and e-invoicing infrastructure, makes sure each period's returns are prepared on time, and closes out the year with the corporate tax return — so you always know where things stand.

Common Mistakes
Delaying the notarisation of statutory books after incorporation
A late notarisation can leave gaps in the first-period records.
Noticing the e-invoicing transition date too late
Issuing paper invoices after the requirement takes effect can be treated as invalid.
Missing the VAT return deadline

Mixing the partner's current account with company expenses
This mix-up affects the accuracy of the year-end financial statements.
