What does BSMV mean, and how is it calculated? In this guide, you can find current rates, calculation methods, applicable transactions, and other important details regarding the Banking and Insurance Transactions Tax (BSMV).

The Banking and Insurance Transactions Tax (BSMV) is one of the cost items encountered in various transactions within the banking and insurance sectors.
This tax, which is frequently encountered by individuals and businesses carrying out financial transactions, is collected on interest, commissions, expenses, and service revenues.
BSMV may apply particularly to loans, foreign currency transactions, insurance services, and various banking services. Since this mandatory tax is collected on behalf of the government from banking transactions, calculating it correctly is important for financial planning.
In this article, we cover what BSMV is, how it is calculated, which rates apply, which transactions are subject to the tax, and in which cases exemptions may apply.
BSMV, short for the Banking and Insurance Transactions Tax, is an indirect tax imposed on certain revenues generated from services provided by banks and insurance companies.
The main purpose of this tax is to transfer a certain portion of the income generated from financial sector transactions to the public budget. However, not every transaction carried out by banks is subject to BSMV. The tax applies to the types of transactions and revenues specified under the relevant legislation.
Therefore, the question “What is a BSMV deduction?” can briefly be answered as a legally required tax deduction made from the income a bank earns in return for providing a service.
The abbreviation BSMV stands for Banking and Insurance Transactions Tax. The main regulations concerning this tax are set out under the Law No. 6802 on Expenditure Taxes.
Some of the main financial transactions subject to BSMV include:
Therefore, BSMV is a type of tax that may arise in many different transactions within the financial sector.
How Is BSMV Calculated?
To calculate BSMV, the amount of income subject to tax must first be determined. The applicable BSMV rate for the relevant transaction is then applied to this amount.
BSMV calculation formula:
BSMV Amount = Taxable Income × BSMV Rate
For example, if a bank charges TRY 100 as a commission for a loan-related expense and the applicable BSMV rate is 5%, the calculation is as follows:
TRY 100 × 5% = TRY 5 BSMV
For credit card interest, KKDF may also apply in addition to BSMV. Therefore, searches such as “What are KKDF and BSMV on credit cards?” refer to these two separate tax obligations that may be added to credit interest.
The BSMV rate may vary depending on the nature of the transaction. While a general rate of 5% applies to income from banking services, the rate may be 0% for certain insurance transactions.
| Transaction Type | BSMV Rate |
|---|---|
| Banking service revenues | 5% |
| Loan interest | 5% |
| Credit card interest | 5% (together with KKDF) |
| Mortgage loan interest | No BSMV charged |
| Insurance policies | May vary depending on the transaction; 0% for certain policies |
| Foreign currency transactions | May vary depending on the period and transaction; for example, 0.1% on foreign currency sales |
Note: Since BSMV rates may be updated due to legislative changes, the applicable current rate should be checked before carrying out a transaction.
BSMV is collected on transactions through which banks and insurance companies generate certain types of income. Some transactions that may fall within this scope include:
In general, transactions through which a bank earns income in return for providing a service may be subject to BSMV under the conditions set out by the relevant legislation.

Certain transactions may be excluded from BSMV under specific provisions of the legislation. These may include:
Therefore, the fact that a bank earns income from a particular transaction does not necessarily mean that BSMV will be collected in every case.
The Banking and Insurance Transactions Tax is a type of tax collected from financial transactions and contributes to public revenues.
The main characteristics of BSMV include:
For businesses in particular, the impact of BSMV on costs, whether it can be treated as an expense, and its role in financial planning are important considerations.
The BSMV charge refers to the tax amount calculated on income generated by a bank from certain services. Money transfer fees, EFT charges, loan-related expenses, and various commissions are examples of items that may fall within this scope.
The tax rate applicable to financial services may vary depending on the type of transaction. For loan-related transactions, the following rates apply in the examples provided:
The frequently searched question “What is BSMV interest?” essentially refers to the tax calculated on a bank's interest income.
A significant portion of the income banks generate from various services provided to their customers may fall within the scope of BSMV. Examples include:
Whether these types of income are subject to BSMV is determined according to the applicable legislative provisions.
BSMV rates may be changed in line with economic conditions and public policies. Rates applicable to certain transactions may be updated through Presidential decisions or relevant legislative regulations.
For example, the BSMV rate applied to foreign currency sales has changed over previous periods. Therefore, businesses and individuals carrying out financial transactions should monitor current rates to ensure accurate cost calculations.
Certain transactions may qualify for a BSMV exemption or may be subject to a different rate. Various exemptions may be introduced through regulations designed to support specific areas of economic activity.
Examples include:
If a transaction falls within an applicable exemption, BSMV may not be collected or the tax rate may be applied at 0%.
Although the calculation process may vary depending on the transaction, the basic procedure can be summarized as follows:
Suppose a bank charges TRY 200 for a loan allocation service and applies a 5% BSMV rate to this transaction.
TRY 200 × 5% = TRY 10 BSMV
In this case, the total amount payable by the customer would be:
TRY 200 + TRY 10 = TRY 210
In conclusion, to calculate BSMV correctly, it is first necessary to determine whether the transaction falls within the scope of the tax and then identify the current rate applicable to that particular transaction.
