FAQ
- How is the long-term holding deduction applied?
- Based on the general real estate schedule (Table 1), it deducts 2% of the capital gain per year from the third year of ownership, up to a maximum of 30%. Special cases such as a single home per household (up to 80%) are not reflected.
- How does the tax rate change with the holding period?
- For general real estate, it applies a flat 50% under 1 year, a flat 40% for 1-2 years, and the progressive base rate of 6-45% for 2 years or more, plus a 10% local income tax.
- Will this match my actual tax bill?
- This is a rough estimate for reference. The actual amount can differ depending on the number of homes, heavy taxation in regulated zones, exemptions and reductions, and special deductions, so confirm the exact figure with the tax office or a tax professional.
