One of the most important issues to consider when buying and selling a house, plot, workplace, or land is the “5-Year Rule”. If you sell a property before 5 years have passed after purchasing it and you make a profit from this sale, the income you obtain may be taxable under certain conditions.

So what exactly is the 5-year rule, in which cases does tax arise, and which exemptions apply? Here’s what you need to know.

What Is the 5-Year Rule in Real Estate?

According to Article 80 (repeated) of the Income Tax Law; if an acquired immovable property is sold within 5 years from the acquisition date, the gain obtained is considered “Capital Gain” and may be subject to income tax.

• If the property is sold before 5 years have passed, tax is calculated on the net gain obtained.
• If the property is sold after 5 years have passed, no capital gains tax is paid on the gain obtained.

How Is the 5-Year Period Calculated?

The period is calculated based on the acquisition date on the title deed.

For example, if you purchased a property on 15 May 2021, you must wait until 16 May 2026 to be able to sell it tax-free.

The Most Important Exemption: Properties Acquired Through Inheritance and Donation

The most important exception to the 5-year rule is the method of acquisition of the property.

If the property came to you;

• through inheritance,
• through donation (gift),

the 5-year condition does not apply. For such properties, regardless of the sale date, no capital gains tax arises. This is because the property was acquired free of charge (gratuitously).

How Is Capital Gains Tax Calculated?

The tax calculation is not made solely on the difference between the purchase and sale prices. Net gain is determined by taking into account the inflation effect and various expenses.

1. Updating the Purchase Price

The purchase price of the property is updated using the Domestic Producer Price Index (D-PPI) data announced by TURKSTAT.

Thanks to this process, the current cost value of the property is calculated and the effect of inflation is taken into account.

2. Deducting Statutory Expenses

From the sale price;

• Updated purchase cost,
• Title deed fee,
• Statutory expenses such as loan interest

are deducted to calculate the net gain.

3. Applying the Exemption Amount

The capital gains exemption amount, which is re-determined each year, is deducted from the calculated net gain.

4. Calculating Income Tax

The amount remaining after the exemption constitutes the income tax base and is taxed according to the income tax tariff of the relevant year.

Tax Return Filing Period

If you have made a sale that falls under the 5-year rule and exceeds the exemption limit, you must declare this gain.

When Is the Tax Return Filed?

The income tax return must be filed in March of the year following the year in which the sale took place.

For example, if you sold your property in 2025, you must file your return in March 2026.

Where Is the Tax Return Filed?

Declaration procedures can be carried out online via the Revenue Administration’s Ready Declaration System. In this way, you can complete your transactions without going to the tax office.

What Happens If the Tax Return Is Not Filed?

Since title deed transactions are monitored electronically, sales transactions can be easily identified by the Ministry of Finance.

If the declaration obligation is not fulfilled;

• You may not be able to benefit from the capital gains exemption,
• A tax loss penalty may be imposed,
• Late interest may be added to the calculated tax.

For this reason, it is of great importance to fulfill tax obligations on time in property sales.
