Capital Gains Tax Calculator
Subtract expenses, the long-term holding deduction, and the basic deduction from a property gain, then apply progressive rates.
A simple estimate using general rates and deduction. Confirm actual tax with a professional or the tax service.
How is it calculated?
Gain = sale price − purchase price − expenses. If held 3+ years, the general long-term holding deduction (2%/year, up to 30%) is subtracted to get taxable income; after the 2.5M won basic deduction, progressive rates of 6–45% apply. Local income tax adds 10% of the computed tax.
When to use it
- Pre-sale simulation: estimate the tax burden at a target sale price to gauge net proceeds.
- Holding-period comparison: see how the long-term deduction grows at 3, 5, and 10 years.
- Expense input: enter acquisition tax, brokerage, and legal fees to lower the tax base.
Things to note
- This is a simple estimate using general rates and the general long-term deduction (table 1). It doesn't reflect single-home exemptions, multi-home surcharges, short-term (under 1–2 years) surcharges, or regulated-area rules.
- Actual tax varies greatly by timing, number of homes, and exemption eligibility.
- Always confirm with a tax accountant or the National Tax Service simulator.

How is the long-term holding deduction applied?
This calculator uses the general property basis (table 1): 2%/year from year 3, up to 30% at 15 years. A single high-value home may qualify for up to 80% (table 2) based on residence and holding requirements, so real results can differ.
Does it handle the single-home exemption?
No. This is a simple estimate that ignores exemptions and reductions. Single-home exemption and temporary two-home rules are complex and need a tax accountant or the official simulator.
What counts as expenses?
Acquisition tax, brokerage fees, legal costs, and capital expenditures (e.g., balcony expansion). Routine repairs are generally not recognized, so check the tax authority's criteria.
Are the amounts stored?
No. All calculation happens only in your browser and the amounts are never sent to or stored on a server.
