How to calculate the area of property deed tax?
Recently, the calculation method of property deed tax has become a hot topic, especially the issue of how the area of the house affects the deed tax rate. Many home buyers have doubts about the calculation standards of deed tax when applying for real estate certificates. This article will combine the hot content on the Internet in the past 10 days to analyze the area calculation method of real estate deed tax in detail, and provide structured data for reference.
1. Basic concepts of real estate deed tax

Real estate deed tax refers to a tax that home buyers need to pay when buying, selling, gifting or exchanging a house. The deed tax rate is usually related to the area of the house, the nature of the house (such as first home, second home) and local policies. The following are the main basis for deed tax calculation:
| House type | Area range (square meters) | Deed tax rate (%) | 
|---|---|---|
| first suite | ≤90 | 1 | 
| first suite | >90 | 1.5 | 
| Second suite | ≤90 | 1 | 
| Second suite | >90 | 2 | 
| Three sets or more | No area limit | 3-5 (different from place to place) | 
2. Calculation method of property area
The area calculation for property deed tax is usually based on the "building area" registered on the property certificate, but there may be differences in different regions. The following are common area calculation rules:
| area type | definition | Is it included in the deed tax area? | 
|---|---|---|
| Building area | The area measured by the perimeter line of the exterior wall of the house | Yes | 
| Inner area | Actual usable area inside the house | No | 
| Pool area | Shared area of public areas (such as elevators and corridors) | Yes | 
3. Answers to hot questions
Based on recent questions from netizens, here are the answers to several popular questions:
1. Is the basement or garage included in the deeded area?
Generally speaking, the basement or garage is not included in the residential area if it is priced separately; however, if it is sold in conjunction with the house, it may be included in the total area.
2. Do I need to pay deed tax for the donated area?
If the area (such as balcony, terrace) donated by the developer is not reflected on the property certificate, the deed tax is usually not calculated; if it has been registered, the tax needs to be paid based on the actual area.
3. Are there differences in deed tax policies in different regions?
Yes, some areas may have preferential policies for first-time home buyers or for talents. For example, some cities have lower tax rates for first-time apartments with an area of ≤144 square meters.
4. Summary
The calculation of area for property deed tax involves many factors, and home buyers need to focus on the building area and local policies. It is recommended to consult the tax department or professional organization before purchasing a house to avoid tax deviations due to errors in area calculation. The following is a simplified calculation example:
| Total house price (10,000 yuan) | Area (square meters) | House type | Deed tax amount (yuan) | 
|---|---|---|---|
| 300 | 85 | first suite | 30000 | 
| 500 | 110 | Second suite | 100000 |
