Quick answer: To change a company address in Türkiye, first identify whether the move stays within the same Trade Registry jurisdiction, transfers the registered office to another registry jurisdiction, merely corrects an address changed by the municipality, or creates an additional workplace instead of moving the head office. That classification determines the corporate decision, MERSİS application and supporting documents. Trade Registry registration is only one layer: tax, SGK, banking, licences, contracts and communication records may also need separate updates.
This guide covers registered-office change. For choosing a compliant address before the move, use Registered Business Address in Turkey. For keeping MERSİS, tax and operational records aligned, use Company Address in Turkey: Record Consistency Guide. If the existing head office will remain and another location is opening, use the separate second office or additional workplace guide.
Start by Classifying the Address Change
| Scenario |
What changes |
Why the route matters |
| Address change within the same Trade Registry jurisdiction |
The registered head-office address changes, but the competent registry remains the same |
The current registry’s LLC or JSC address-change checklist applies |
| Registered-office transfer to another registry jurisdiction |
The company’s registered centre moves to a different registry area |
This is a merkez nakli; it generally requires an articles-of-association amendment and transfer documents |
| Municipal renumbering or administrative correction |
The company has not chosen to move, but the official address record changes |
The registry may use a separate correction route supported by a municipality, organised industrial zone or free-zone authority letter |
| Additional workplace or branch |
The existing head office remains and another operating location is added |
This is not a head-office address change and may require workplace or branch analysis |
Route rule: Do not prepare the resolution until the competent Trade Registry confirms which of these transactions the move represents.
The correct route depends on whether the company is moving within one registry area, transferring its centre or adding another workplace.
Pre-Filing Check: Is the New Address Usable?
Before approving the move, confirm that the company can prove its right to use the new address and that the premises fit the intended activity. A low-cost address is not useful if the provider cannot supply the required documents, official mail cannot be managed, or the activity needs physical premises, municipal approval or a sector licence that the location cannot support.
- Verify the exact address through the official address system and the building/unit information.
- Review the lease, sublease, title record or service agreement supporting the right to use the address.
- Check whether the activity is compatible with the building, zoning, licence and provider rules.
- Confirm how tax-office verification and official correspondence will be handled.
- Map employee, SGK, municipality and sector-regulator consequences before the effective move date.
- Keep a continuity plan for mail, KEP, bank notices and customer/supplier communications.

LLC and JSC Decisions Are Not Interchangeable
The old shortcut “every company needs a notarised board resolution” is inaccurate. The decision document depends on the legal form and transaction.
| Company / route |
Current Istanbul Trade Registry checklist |
Control point |
| LLC (Ltd. Şti.), address change within the registry area |
Application petition and a notarised copy from the general assembly decision and negotiation book; attendance documentation where applicable |
The MERSİS preview address must match the resolution |
| JSC (A.Ş.), address change within the registry area |
Application petition and a notarised copy of the board resolution from the board decision book |
The MERSİS preview address must match the resolution |
| LLC or JSC moving its registered centre to another registry area |
A broader merkez nakli file, including the competent corporate decision and changed centre clause; old-registry and new-registry documents may be required |
This is not the same filing as an ordinary local address change |
| Municipality-led renumbering |
Petition plus an official letter showing the former and updated addresses, subject to the registry checklist |
Use the special correction route rather than inventing a corporate move |
These are Istanbul checklist examples current at the review date. Another Trade Registry Directorate may request a different local form, appointment process or supporting item. The company’s articles, representation rules, meeting/decision validity and any Ministry-permission status must also be checked.
An LLC and a JSC do not use the same decision document for every address-change route.
Foreign Shareholders: When Overseas Documents Matter
A Turkish company’s address change does not automatically mean that every foreign shareholder must obtain a new apostilled document. Foreign-issued records become relevant when the transaction relies on a foreign corporate shareholder’s authority evidence, a foreign-signed power of attorney, a representative decision or another overseas document required for the corporate decision or filing.
When an overseas record is required, determine the correct apostille, Turkish consular legalisation or applicable exemption route for that document and issuing country. Translation and Turkish notarial handling are separate acceptance questions. Use Apostille for Turkey Documents, Sworn Translation in Turkey and Power of Attorney in Turkey for those separate decisions.
Step-by-Step Company Address Change Process
- Classify the transaction. Confirm local address change, registered-centre transfer, administrative correction or additional workplace.
- Secure and verify the new address. Check the address string, right-to-use evidence, activity suitability and official-mail plan.
- Prepare the correct corporate decision. Use the LLC/JSC and transaction-specific authority, meeting, wording and book requirements.
- Create the MERSİS application. Enter the change, obtain the request number and follow the competent registry’s appointment/submission process.
- Match every address field. Istanbul Trade Registry specifically instructs applicants to use the MERSİS “Change Preview” and ensure the displayed address is identical to the decision.
- Submit the registry package. File the petition, corporate decision and route-specific supporting documents.
- Verify registration and publication. Check the updated Trade Registry record and the corresponding Trade Registry Gazette publication where applicable.
- Complete the post-registration update matrix. Do not assume that one registry entry has updated every institution, contract or operational system correctly.
The MERSİS address, corporate decision and registry submission should use one verified address string.
Same Registry Area vs Registered-Centre Transfer
This distinction deserves special attention because the document burden can change materially.
Move within the same registry area
The registry remains responsible for the company. The filing normally centres on the entity-specific decision, petition and current registry checklist.
Move to another registry jurisdiction
The company transfers its registered centre. Current Istanbul checklists refer to the relevant old-registry certificate under the Trade Registry Regulation, a chamber registration declaration and a general assembly decision containing the amended centre clause, with additional items depending on the company and file. A JSC subject to Ministry permission may also need the applicable permission documents.
Do not describe a registered-centre transfer as a simple address correction. Confirm the departure and arrival registry procedures before scheduling the corporate decision.
Tax Office: Verify the Change Instead of Assuming Data Flow
Gelir İdaresi Başkanlığı (GİB) treats a workplace move as an address change and the general tax-notification framework uses a one-month change-notification period. However, current GİB guidance also reflects VUK General Communiqué No. 546: where a change that is otherwise reportable to the tax office is registered with the Trade Registry within the statutory tax-notification period, the tax notification is treated as timely completed and the taxpayer does not need to submit the same change separately to the tax office.
That does not mean “nothing needs checking after the registry filing.” Verify the company’s current tax-office assignment, tax plate/address record, e-notification profile and whether an address-verification visit or other evidence request applies. Also distinguish a registered Trade Registry change from a separate tax-only operating-location event: current GİB guidance states that increases or decreases in the number of workplaces other than branches continue to be reportable to the tax administration. The company’s licensed SMMM/CPA should therefore confirm which route the actual move creates.
SGK: The Employer and Workplace Facts Control the Route
SGK action is relevant when the company has an active registered workplace and insured employees. SGK’s official employer guidance states that where a workplace moves to an address in another province, the workplace declaration is submitted to the unit responsible for the new address no later than ten days after the move. A move within the same province and transfer of employees between workplace numbers can follow different mechanics and exceptions.
Before moving staff, confirm whether the existing workplace number continues, a new workplace registration is needed, and how employee transfer, payroll and workplace records will be handled. Do not add SGK steps to a company with no applicable employer/workplace trigger merely because its Trade Registry address changed.
Tax and SGK consequences are separate from the Trade Registry filing and depend on the company’s actual records and workforce.

How Long Does a Company Address Change Take?
There is no responsible universal number. A complete same-registry filing can be materially simpler than a registered-centre transfer, while a regulated business, foreign authority document, meeting-notice issue or address mismatch can add dependencies.
Build the project schedule around milestones:
- new-address verification and right-to-use evidence;
- valid corporate decision;
- MERSİS request and registry appointment/submission;
- registration/publication verification;
- tax and SGK actions where triggered;
- bank, licence, contract and system updates;
- mail and operating continuity at the new location.
The competent registry, tax office, SGK unit, bank and sector authority each follow their current procedure and timing, so the project schedule should be built around those milestones.
What Does a Company Address Change Cost?
The cost depends on the route and file. Possible categories include registry/chamber/Gazette payments, certified decision copies, foreign-document handling where genuinely required, registered-address or workspace cost, licensed professional fees, licence updates, courier/signage and system changes.
Ask for a scope-based budget that separates:
- Workon coordination;
- official and pass-through payments;
- licensed professional work;
- variable document costs;
- the new address/workspace service;
- post-registration operational updates.
Do not rely on an old fixed TRY figure or assume that a local address change and an inter-registry centre transfer have the same cost.
Official 2026 SMMM professional-fee reference
The 2026 SMMM professional-fee tariff lists TRY 4,540 for address-change professional work. This is a minimum/professional SMMM tariff reference; it is not the total address-change cost and does not include Trade Registry/chamber/Gazette payments, new-address or workspace fees, notary/translation/legalisation, legal advice or Workon coordination.
If the transaction is not a simple address change—for example, a registered-centre transfer that also requires an articles-of-association amendment—another professional-service row may become relevant. Do not automatically add an amendment fee unless the actual route and professional scope require it.
For future annual updates, verify the current year through the İSMMMO Professional Fee Tariffs archive and the corresponding TÜRMOB / Official Gazette tariff.
Common Address-Change Errors
- Preparing a JSC board decision for an LLC—or the reverse.
- Treating a registered-centre transfer as an ordinary local address change.
- Using an address string in the decision that differs from the MERSİS preview.
- Signing the new address agreement before checking activity and licence suitability.
- Assuming every foreign document needs an apostille, translation and notarisation.
- Assuming Trade Registry registration has completed tax, SGK, bank and regulator updates.
- Moving employees without mapping the SGK workplace and employee-transfer route.
- Ending mail at the former address before official channels and counterparties are updated.

Frequently Asked Questions
First classify whether the move is within the same Trade Registry jurisdiction, a registered-centre transfer to another registry, a municipality-led address correction or merely an additional workplace. Then prepare the company-type and route-specific corporate decision, create the MERSİS application and file the required documents with the competent Trade Registry.
No. The required decision document depends on the company type and transaction. Current Istanbul practice uses the LLC general-assembly decision route for an ordinary LLC address change and a board resolution for an ordinary JSC address change, while an inter-registry centre transfer can require a broader articles-of-association amendment process.
No. The file can differ for a local address change, centre transfer, municipal renumbering or another scenario. The new address and right-to-use evidence should be validated first, then the current registry checklist should be followed for the exact company type and route.
For tax notifications, current GİB guidance reflects VUK General Communiqué No. 546: a tax-reportable change that is registered with the Trade Registry within the statutory notification period is treated as timely reported and does not require the same separate tax-office notification. Still verify the resulting tax records, because other operating-location events can follow a separate tax route. SGK is a different system and its action depends on whether an employer\/workplace move or new workplace trigger exists.
Foreign ownership does not create a separate address-change regime by itself. Foreign documents become relevant only where the filing relies on overseas corporate authority, a foreign-signed power of attorney or another foreign-issued record. The correct legalisation and translation route depends on the specific document and issuing country.
There is no safe universal two-to-four-week promise. A same-registry move can be simpler than a centre transfer, while foreign documents, corporate approvals, registry corrections, tax or SGK actions and sector or banking updates can add dependencies. Plan around milestones rather than a fixed duration.
