MASAK (Financial Crimes Investigation Board) is Türkiye’s central financial intelligence authority responsible for preventing the laundering of criminal proceeds, terrorist financing, and the proliferation of weapons of mass destruction. Operating under the Ministry of Treasury and Finance since 1997, MASAK plays a pivotal role in shaping Türkiye’s compliance framework by regulating both financial and certain non-financial institutions.
This article, prepared by Bayraktar Attorneys, explains MASAK’s scope, legal basis, reporting obligations, and the legal risks of non-compliance. If you are a foreign investor, financial institution, real estate developer, or service provider in Türkiye, understanding MASAK regulations is essential to maintaining legal integrity.
MASAK stands for Mali Suçları Araştırma Kurulu – the Financial Crimes Investigation Board. It was established under Law No. 4208 on the Prevention of Laundering Proceeds of Crime and began operations on February 17, 1997. As a specialized department of the Ministry of Treasury and Finance, MASAK functions as Türkiye’s national Financial Intelligence Unit (FIU).
The institution’s primary mission is to control financial values derived from criminal activities and to implement preventative measures against:
Money laundering,
Financing of terrorism,
Financing of weapons of mass destruction (WMDs).
MASAK’s authority stems from:
The Council of Europe Convention on Laundering, Search, Seizure and Confiscation of the Proceeds of Crime, to which Türkiye is a signatory.
Law No. 5549 on the Prevention of Laundering Proceeds of Crime, which provides the domestic legal basis.
The Regulation on Measures Regarding Prevention of Laundering Proceeds of Crime and Terrorist Financing.
These instruments regulate MASAK’s investigative powers and the obligations of private sector actors, especially financial institutions and designated non-financial businesses and professions (DNFBPs).
The Council of Europe Convention outlines Türkiye’s obligations for criminal asset seizure, investigation procedures, and the criminalization of laundering offenses.
Preventing the disposal or transfer of suspicious assets.
Allowing courts and authorities to access commercial records and banking information without invoking bank secrecy.
Using special investigative techniques like communication surveillance and data tracking.
Protecting the legal rights of persons affected by enforcement.
Transferring or converting assets with knowledge of their illicit origin to hide their source.
Concealing the nature or ownership of illegal assets.
Acquiring or using such assets while knowing their origin.
Aiding or conspiring in any of the above activities.
According to Law No. 5549, the following sectors are considered obligated institutions under Turkish AML law:
Banks, insurers, investment firms
Real estate agencies, car and machinery dealers
Jewelers, art dealers, gaming operators
Notaries and sports clubs
Lawyers and mediators (under limited conditions)
NGOs, foundations, company service providers
These sectors must adopt internal controls, file suspicious transaction reports, and appoint compliance officers where applicable.
Before initiating any transaction, institutions must verify the identity of customers and beneficiaries. The rules differ slightly depending on whether the institution is a financial entity or DNFBP.
Failure to comply results in an administrative fine of 30,000 TL.
If there is suspicion that an asset is linked to crime or terrorism, it must be reported to MASAK immediately using the STR form.
Reports must be submitted within 10 business days from the date of suspicion. Paper submissions must be signed and retained for 8 years.
Authorized institutions may submit reports electronically through EMIS.ONLINE.
Failure to submit STRs may result in fines up to 50,000 TL, and breaches of confidentiality can lead to 1–3 years imprisonment and criminal fines.
Transactions above certain thresholds must be regularly reported to the Ministry. Businesses must also:
Retain all relevant records for 8 years
Provide documents when requested by MASAK inspectors
Cooperate during audits and investigations
Failure to comply may result in prison sentences of 1–3 years and monetary fines.
Large institutions must implement a compliance program under the Regulation on Compliance with AML/CFT Measures, published in the Official Gazette (16.09.2008, No. 26999).
This includes:
Appointing a compliance officer,
Training staff,
Setting up internal audit systems,
Risk management protocols.
Penalties for failure to implement a compliance program start with a formal warning. If deficiencies are not corrected, administrative fines can rise up to 500,000 TL, and even lead to license suspension.
