Turkey Cancels 6,134 Citizenship Decisions: What Investors Must Know

In August 2026, Turkey announced one of the largest reviews of citizenship decisions in the history of its citizenship-by-investment (CBI) programme. A total of 6,134 citizenship decisions were cancelled or withdrawn, while authorities also launched a major criminal operation against a network accused of using fake property valuation reports and sham transactions to obtain Turkish citizenship.

The scale of the announcement attracted significant attention, but there is an important point that every current investor should understand: the valuation system used for Turkish citizenship today is not the same system under which the historic valuation abuses occurred.

Since 2024, citizenship-related property valuations have been centralized under GEDAŞ Gayrimenkul Değerleme A.Ş., a company affiliated with the Ministry of Environment, Urbanization and Climate Change and TOKİ. Since 9 December 2024, the system has been strengthened further through the introduction of the TTB — Taşınmaz Edinim Sureti ile Vatandaşlık Kazanımına Esas Tutar Tespit Belgesi.

That distinction is central to understanding what happened, who may actually be at risk, and why a new investor applying under the current GEDAŞ system is in a very different position from an investor whose application relied on the previous private-appraiser framework.

What Actually Happened in August 2026?

On 4 August 2026, the Turkish Ministry of Interior announced an operation across 16 provinces against a network accused of arranging fraudulent real estate valuations and improper citizenship applications. According to the Ministry, 72 suspects were apprehended as part of the operation.

Authorities said the scheme involved attempts to use false or improper property appraisal documentation in citizenship applications. The wider review of Turkish citizenship files, however, covered more than this single criminal investigation.

The Ministry's official figures are important:

• 1,150 investors were found to have been involved in sham or improper investment transactions.
• The investment eligibility certificates of those investors were cancelled.
• Including family members, 5,391 citizenship decisions were cancelled in connection with these improper investment cases.
• A further 743 people, including investors and family members, had citizenship decisions withdrawn on national-security or public-order grounds.
• The combined total was therefore 6,134 people.

It is therefore not accurate to say that all 6,134 citizenship cancellations resulted from fake property valuations. The fake-appraisal investigation is a major part of the enforcement action, but the total figure also includes separate national-security and public-order cases.

The Most Important Point: Turkey Changed the Valuation System in 2024

Many reports discussing the August 2026 operation fail to make a very important distinction between the old valuation system and the system that applies today.

Historically, citizenship-related property valuation reports were prepared through SPK-licensed private valuation companies. Although the companies and valuers were licensed, the structure relied on a much larger private appraisal market.

That system has since changed.

According to the Turkish Ministry of Interior, from 2024 onward citizenship-related real estate valuations have been prepared under the coordination of the Land Registry and Cadastre Directorate (TKGM) through GEDAŞ.

GEDAŞ is not an ordinary real estate agency, developer-selected appraisal company or broker. It is a real estate valuation company affiliated with TOKİ and the Ministry of Environment, Urbanization and Climate Change.

For a current Turkish citizenship application, an investor does not simply choose a private SPK valuation company and ask it to prepare the citizenship valuation. TKGM states that the citizenship valuation request is made through the official WebTapu system and obtained from GEDAŞ.

December 2024: The TTB System Made the Process Even More Controlled

The system changed again on 9 December 2024 with the introduction of the Taşınmaz Edinim Sureti ile Vatandaşlık Kazanımına Esas Tutar Tespit Belgesi (TTB).

The TTB is now the key document used to establish the amount of real estate investment that can be accepted for citizenship purposes.

The process works through the government's digital infrastructure:

1. A citizenship-purpose valuation request is made through WebTapu/TADEBİS.
2. GEDAŞ prepares the underlying property valuation.
3. The investment amount that can be accepted for citizenship purposes is determined through the TTB.
4. The TTB is transmitted electronically through TADEBİS to TAKBİS/WebTapu.
5. A physically submitted TTB is not accepted in place of the electronically transmitted document.

There is also another important safeguard. TKGM states that TTBs issued by GEDAŞ after 9 December 2024 are produced following software-based evaluation and comparison. Because those checks are already built into the process, TKGM accepts the amount stated on the TTB directly without requiring another separate valuation review.

In practical terms, the investor is no longer relying on a valuation arranged privately between a seller, intermediary and appraisal firm. The citizenship valuation passes through a centralized system controlled by the relevant public authorities.

Why the Old Fake-Appraisal Model Is Much Harder Under the Current System

The alleged historic fraud model depended heavily on the ability to manipulate the value presented in a citizenship file.

A property worth significantly less than the citizenship threshold could theoretically be supported by an inflated appraisal and combined with other false documentation to make the transaction appear eligible.

The current structure removes one of the main points where that manipulation could previously occur.

Today:

• The investor does not freely select a private appraisal company for the citizenship valuation.
• The citizenship valuation is obtained through GEDAŞ via WebTapu.
• The citizenship investment amount is established through the official TTB system.
• The TTB is electronically integrated with the government systems used for the transaction.
• Post-9 December 2024 TTBs go through software-based evaluation and comparison before issuance.
• TKGM then processes the amount shown by that system directly for citizenship purposes.

This makes the current process fundamentally different from the older framework involved in many of the historic valuation concerns.

No legal or administrative process should literally be described as having zero risk. However, the specific risk of an investor unknowingly relying on a privately arranged, artificially inflated citizenship valuation has been greatly reduced under the GEDAŞ and TTB system.

For a new investor, the GEDAŞ/TTB amount is the official valuation amount used by TKGM for the citizenship transaction. An applicant who follows the official process is therefore not expected to independently determine whether a private appraiser has artificially increased the citizenship value — the current system was specifically structured to remove that private-appraiser dependency.

This Is Why Old and New Citizenship Files Should Not Be Treated the Same

A citizenship application prepared several years ago and an application prepared today should not be placed in the same risk category.

An older application may have relied on a private SPK-licensed valuation company, a valuation method used before GEDAŞ became responsible for citizenship valuations, and documentation prepared before the current TTB controls existed.

A new application operates under a different structure.

The Ministry of Interior itself makes this distinction when explaining the current system, specifically noting that GEDAŞ has been used for these valuations since 2024.

Therefore, news about historic fraudulent appraisal files should not automatically be interpreted as evidence that a person purchasing property today through the GEDAŞ/TTB system faces the same valuation risk.

GEDAŞ Does Not Replace the Other Citizenship Requirements

GEDAŞ significantly reduces valuation-related risk, but valuation is only one part of a citizenship-by-investment transaction.

Under the current rules, reaching $400,000 on the valuation alone is not sufficient.

TKGM states that the relevant values must separately satisfy the required investment threshold, including:

• the amount supported through the citizenship valuation/TTB;
• the sale value declared in the official title deed or the value stated in the qualifying preliminary sale agreement;
• the required foreign-exchange documentation; and
• the actual payments and bank-transfer records.

This is extremely important because GEDAŞ prevents one type of problem — manipulation of the official citizenship valuation — but it cannot make a fictitious payment real.

If an investor claims to have purchased a $400,000 property but the required money was never genuinely paid, GEDAŞ does not protect that transaction from investigation.

Who Is Actually at Risk?

What Should Existing Investors Do?

If you obtained Turkish citizenship through a property purchase under the older system, there is no reason to assume your citizenship is automatically at risk.

The key question is whether the underlying investment was genuine.

You should retain:

• your original property valuation report;
• the title deed;
• bank transfer receipts;
• foreign-exchange documentation;
• seller payment records;
• the investment eligibility certificate;
• the three-year non-sale undertaking; and
• any contracts and invoices connected with the purchase.

If the property was genuinely purchased, the required amount was genuinely paid and there was no artificial valuation arrangement, the fact that the transaction took place before GEDAŞ does not itself make the citizenship improper.

What Should a New Investor Do?

For a person investing today, the process is much simpler from a valuation-risk perspective.

1. Use the official GEDAŞ valuation process. Citizenship valuation requests are made through WebTapu and processed through GEDAŞ.
2. Check the TTB amount before completing the citizenship structure. The qualifying investment amount must satisfy the citizenship requirement.
3. Make the real payment. Never participate in arrangements where part of the purchase price is returned, temporarily circulated or only shown on paper.
4. Make sure the title deed value, payment records and other required financial documents satisfy the citizenship rules.
5. Keep the three-year restriction intact. Do not transfer the property or remove the undertaking early without first understanding the citizenship consequences.
6. Keep the complete transaction file. The strongest protection against any future review is a genuine transaction supported by complete records.

Is a GEDAŞ Valuation Safe to Rely On?

For citizenship purposes, GEDAŞ is the official valuation channel identified by TKGM. The applicant is not required to obtain a separate private appraisal and decide which value the government may accept.

Under the post-9 December 2024 system, the TTB is prepared from the GEDAŞ valuation and subject to software-based evaluation and comparison. TKGM states that these TTBs are then accepted directly on the amount stated in the document without a further separate valuation examination.

This is a major difference from the older system.

It also means that an investor should not be frightened by a later claim that an independent private appraiser might have valued the property differently. For citizenship purposes, what matters is the official investment amount accepted through the applicable GEDAŞ/TTB procedure, together with compliance with the other legal requirements.

Does This Mean Turkish Citizenship by Investment Is Unsafe?

No.

The 2026 enforcement actions show that Turkey is reviewing and cancelling citizenship obtained through improper transactions. That is very different from saying legitimate citizenship-by-investment applications are unsafe.

In fact, the changes made since 2024 have made the valuation side of the programme far more controlled.

The old private-appraiser structure has been replaced for citizenship purposes by a centralized GEDAŞ process. The TTB system introduced in December 2024 adds electronic transfer, software-based checks and comparison controls.

For a genuine investor, this is positive. It means that one of the most sensitive parts of the old citizenship process — the possibility of an artificially inflated private appraisal — is now substantially harder to manipulate.

Frequently Asked Questions

Were all 6,134 citizenship cancellations caused by fake appraisals?

No. According to the Ministry of Interior, 5,391 people, including family members, were affected by cancellations connected with improper investment transactions. Another 743 people were affected on national-security or public-order grounds. Together these groups produced the widely reported figure of 6,134.

Do citizenship applicants still choose an SPK-licensed appraisal company?

Not in the old sense. TKGM's current guidance states that the valuation for citizenship purposes is obtained from GEDAŞ through WebTapu. The Ministry of Interior also confirms that the GEDAŞ system has applied since 2024.

What is GEDAŞ?

GEDAŞ Gayrimenkul Değerleme A.Ş. is a real estate valuation company affiliated with TOKİ and the Ministry of Environment, Urbanization and Climate Change. It operates throughout Turkey and is the institution used for citizenship-purpose real estate valuations under the current system.

What is the TTB?

The TTB is the Taşınmaz Edinim Sureti ile Vatandaşlık Kazanımına Esas Tutar Tespit Belgesi. It establishes the amount of a real estate investment that may be accepted for Turkish citizenship purposes.

When did the TTB system start?

The current TTB rules entered into force on 9 December 2024.

How long is a TTB valid?

TTBs issued under the current system are valid for six months. If the relevant citizenship transaction is not filed within that period, the underlying valuation must be renewed according to the applicable TKGM procedure.

Can a developer choose an appraiser who will give the property a higher citizenship value?

The current system is specifically structured to prevent the citizenship valuation from operating that way. The citizenship-purpose request is made through the official system and handled through GEDAŞ rather than simply allowing the parties to select a private appraisal firm whose valuation will then be used for the application.

Can my citizenship be cancelled because my property falls in value later?

A later movement in the real estate market is not the same as fraud at the time of investment. The relevant question is whether the citizenship requirements were legally satisfied when the qualifying transaction was carried out and whether the required investment and payment were genuine.

If GEDAŞ says my property qualifies, is that enough?

It resolves the official valuation side of the transaction, but all other requirements still have to be satisfied. The title deed or qualifying sale agreement, payment amounts, banking records, foreign-exchange documentation and the three-year undertaking must also comply with the citizenship rules.

Should I avoid Turkish citizenship by investment because of the 2026 operation?

For a genuine investor using the current system, the operation should be understood primarily as enforcement against improper historic transactions rather than as a warning that legitimate new applications are unsafe.

Today's investor applies under a materially different valuation framework: GEDAŞ, WebTapu, TTB, electronic government records and software-based valuation checks.

Conclusion

The August 2026 citizenship cancellations are serious, but they need to be understood in the correct context.

Turkey is investigating and reversing citizenship decisions where the underlying investment was improper or where other legal grounds for withdrawal exist. At the same time, Turkey has already changed one of the main systems that made historic real estate valuation abuse possible.

Since 2024, citizenship-related property valuations have been handled through GEDAŞ under TKGM coordination. Since 9 December 2024, the TTB system has added further centralized and software-based controls.

This means a person investing today is not operating under the same valuation framework involved in older fraudulent files.

A legitimate investor who purchases a qualifying property, receives the official GEDAŞ/TTB valuation, genuinely pays the required purchase price through the documented financial system and maintains the required three-year undertaking is in a fundamentally different position from someone who obtained citizenship through an inflated appraisal or a fictitious transaction.

The lesson from the 2026 operation is therefore not that Turkish citizenship by investment has become unsafe. The lesson is that old shortcuts are being investigated while the current system has been redesigned to make those same valuation abuses far more difficult.
