The First Month After Company Formation in Turkey: Mandatory Legal Steps

The publication of your new company in the Turkish Trade Registry Gazette is a moment of triumph. It signifies that your entity has gained legal personality, transitioning from a concept into a recognized commercial actor. However, experienced investors know that this official registration is not the finish line; it is merely the starting gun for a sprint of bureaucratic compliance. The first thirty days following incorporation are arguably the most critical period in the lifecycle of a Turkish company. This is the phase where the legal skeleton of the company is fleshed out with operational authority, fiscal identity, and administrative compliance. Failing to navigate these initial weeks correctly can lead to immediate tax penalties, frozen bank accounts, or a suspension of activity. This guide serves as a comprehensive roadmap for the immediate post-incorporation landscape, detailing the mandatory legal steps that every foreign entrepreneur must execute during the first month.

Step 1: Operationalizing Authority – The Signature Circular

There is a profound semantic and legal distinction in Turkish corporate law between the “Signature Declaration” and the “Signature Circular”. During the formation phase, you provided a declaration to the Trade Registry. However, once the company is registered, you must obtain the Signature Circular from a Notary Public. This document is the “golden key” to your business operations.

The Signature Circular is the official document that proves who has the authority to bind the company and the extent of their powers. It translates the management clauses of your Articles of Association into a practical format accepted by third parties. Without this document, the appointed directors cannot sign contracts, open bank accounts, or authorize transfers. It is the first document any counterparty in Turkey will ask for. Therefore, the very first action after the Trade Registry announcement should be a visit to the notary to have this circular issued. It defines whether a manager can sign alone or requires a joint signature, establishing the governance hierarchy of the firm.

Step 2: The Tax Office “Roll-Call” (Yoklama)

Simultaneously with the Trade Registry filing, your company is automatically notified to the Tax Office. However, the tax authorities operate on a principle of “trust but verify.” They acknowledge your registration but require physical proof of your existence. This verification process is known as the “Yoklama” or tax roll-call.

Within a few days to two weeks of incorporation, a tax officer will physically visit your registered address. This is a critical juncture. The officer’s goal is to verify that the company actually exists at that address and that the activity stated in the Articles of Association is feasible. If you have rented a physical office, the authorized manager must be present to sign the “Yoklama Fişi” (Poll Slip). If you are using a Virtual Office, the process is slightly more streamlined; the Virtual Office provider manages the reception, but the tax officer may still require a digital confirmation or a scheduled visit. Failing this inspection—being absent or having an invalid address—results in the immediate suspension of your tax number. Once the roll-call is successfully signed, the tax office activates your status, allowing you to generate your “Tax Plate” (Vergi Levhası).

Step 3: Obtaining the Tax Plate (Vergi Levhası)

The Tax Plate is the visual proof of your fiscal identity. Historically, this was a physical plate hung on the wall. Today, it is a digital PDF document generated through the Revenue Administration’s (GİB) online system. Despite being digital, it holds immense weight.

By law, this document must be generated and kept available for inspection. It displays your Tax Identity Number, your NACE codes (activity classification), and your registered address. You will need to present your Tax Plate to open a corporate bank account, sign up for utilities, or enter into vendor contracts. It is the primary document used by other businesses to verify your tax status before issuing invoices to you. Obtaining this plate marks the moment your company becomes a fully active taxpayer in the eyes of the state.

Step 4: The Accountant Contract and Power of Attorney

In Turkey, tax compliance is not a DIY (Do-It-Yourself) activity. The law mandates that every company must have a contract with a Certified Public Accountant (CPA – Serbest Muhasebeci Mali Müşavir). You cannot submit your own VAT declarations or corporate tax returns directly to the government; they must be submitted by an authorized intermediary.

Therefore, within the first month, you must formally execute a service contract with your CPA. This contract is registered in the dominance system of the Chamber of Accountants. Alongside this contract, you must issue a specific “Accounting Power of Attorney” at the notary. This PoA authorizes your accountant to represent the company before the Social Security Institution (SGK) and the Tax Office. This step is non-negotiable. Your accountant is your bridge to the state, and establishing this legal link immediately is crucial for filing the first month’s Stamp Duty and VAT declarations, preventing early penalties.

Step 5: Statutory Books and Ledger Certification

Turkish Commercial Code adheres to a strict system of “Statutory Books.” Every company is required to maintain a set of official ledgers—specifically the General Journal , the General Ledger (Defter-i Kebir), and the Inventory Book. Additionally, a Share Ledger and a General Assembly Minute Book must be kept.

These are not just Excel sheets. They are physical or digital books that must be “opened” and certified by a Notary Public. This process is called “Opening Certification” . This certification must be completed immediately upon incorporation. These books are the official memory of the company; in any tax audit or commercial dispute, the judge or auditor will demand to see these notarized ledgers. If they were not certified on time, the company’s financial records are deemed invalid, leading to severe fines and the rejection of VAT deductions.

Step 6: Digital Identity – KEP and E-Signature

Turkey’s bureaucracy has undergone a massive digital transformation, and your company must plug into this ecosystem. Two digital tools are mandatory for corporate operations: the E-Signature (E-İmza) and the KEP Address .

The E-Signature is a USB token that allows the authorized manager to sign documents digitally. It is required to use the MERSIS system, to submit documents to the government, and increasingly, to use online banking. The KEP Address is a Registered Electronic Mail system. It is legally equivalent to a registered letter sent via post. Official notifications from the judiciary or government agencies are often sent to your KEP address. Unlike standard email, KEP provides legal proof of delivery and read receipt. You must obtain a KEP address from an authorized provider and register it. Neglecting this means you might miss a court summons or a tax notification, as the “I didn’t check my spam folder” defense is not valid in Turkish law.

Step 7: Banking and Capital Activation

With the Signature Circular and Tax Plate in hand, you can return to the bank. If you blocked 25% of your capital (for JSCs) prior to incorporation, you can now unblock these funds for company use. If you established an LLC, you can now open your permanent operational accounts.

This is also the stage to activate Internet Banking. Turkish corporate banking is highly advanced but security-focused. The bank will define authorization levels based on the Signature Circular—who can view balances, who can initiate transfers, and who provides the final approval. Setting this up correctly in the first month is vital for operational fluidity, paying suppliers, and, importantly, paying the CPA and tax bills.

Step 8: Social Security (SGK) Registration

If your business plan involves hiring employees—even if it is just one assistant or the manager themselves—you must register the company with the Social Security Institution (SGK). This involves obtaining a “Workplace Registration Number”.

Strict deadlines apply here. You must file an electronic declaration of intent to hire personnel before the employee starts working. If you hire someone and register them a day late, the fines are substantial. For foreign shareholders who are not residing in Turkey, social security registration might not be mandatory for themselves, but if they obtain a work permit and become active employees, they enter the SGK system. Clarifying the social security status of the partners and employees is a priority task for the first thirty days.

Conclusion: Setting the Rhythm of Compliance

The first month after company formation in Turkey is intense. It involves a coordinated effort between the notary, the tax office, the bank, and your accountant. It transitions the company from a legal fiction to an operational reality.

Skipping any of these steps—forgetting the KEP address, missing the tax roll-call, or delaying the ledger certification—creates a “compliance debt” that will inevitably surface during future audits or due diligence.
