Japan vs Thailand Property Tax: What Thai Buyers Actually Pay

What you own

In Japan there is no nationality restriction on owning land or buildings. Ownership is registered in your own name in the property registry (登記簿), and freehold land, a house, and a condominium unit are all available to a foreign buyer on the same terms as a Japanese buyer. Residency status does not change this.

In Thailand, foreign buyers are restricted to condominium units within the 49% foreign quota under Section 19 bis of the Condominium Act, or to leasehold arrangements. Land ownership is closed under the Land Code.

What you pay every year

Japan levies two recurring taxes, both on the assessed value (固定資産税評価額), which for land typically runs at 60% to 70% of market price:

• Fixed asset tax (固定資産税): 1.4% of assessed value, annually, on every property regardless of use or owner
• City planning tax (都市計画税): up to a further 0.3% of assessed value, in urbanization-promotion areas
• Relief: residential land is reduced to 1/6 of assessed value for the first 200 sqm per dwelling and 1/3 above that. There is no exemption for a property simply being your first home.

Thailand levies a single land and building tax on the appraised value set by the Treasury Department, with the rate driven by use:

• Owner-occupied first home: exempt to 50 million baht where you own both land and building, or to 10 million baht where you own the building only. Above the threshold, 0.03% rising to 0.1%.
• Second home onward: 0.02% from the first baht, rising to 0.1% above 100 million baht, with no exemption.
• Commercial or other use: 0.3% to 0.7% by value band.
• Vacant or unused land: 0.3% to 0.7%, escalating a further 0.3% every 3 years of disuse, capped at 3%.

The headline gap on a second property is the number to internalise: roughly 1.4% in Japan against 0.02% in Thailand, both on an assessed rather than market basis. Japanese residential land reductions soften this considerably on a modest owner-occupied plot, but they do not close it.

What you pay to buy

In Japan: real estate acquisition tax (不動産取得税) at 3% of assessed value for residential land and buildings (the statutory rate is 4%, currently reduced), plus registration and license tax (登録免許税) and stamp duty (印紙税). The acquisition tax is billed by the prefecture some months after registration, not at closing.

In Thailand: a 2% transfer fee on the Land Department appraised value, conventionally split between buyer and seller but negotiable, plus either specific business tax at 3.3% or stamp duty at 0.5%, plus withholding tax on the seller.

What you pay to sell

Japan taxes the gain, and the holding period matters more than most buyers expect:

• Held 5 years or less: 39.63% (30% income tax, 9% resident tax, 0.63% reconstruction surtax)
• Held more than 5 years: 20.315% (15% income tax, 5% resident tax, 0.315% reconstruction surtax)

Thailand instead taxes the transaction: specific business tax of 3.3% if the property is sold within 5 years of acquisition, otherwise stamp duty of 0.5%, plus a withholding tax computed on a progressive scale against the appraised value and the number of years held.

1. Do not carry the "no annual tax" assumption into Japan. Budget the recurring bill from the first year. On a property you intend to hold for a decade, the accumulated fixed asset and city planning tax is a material share of total cost, and it is charged whether or not the property earns anything.
2. The 1.4% applies to assessed value, not to what you paid. The fixed asset tax assessed value (固定資産税評価額) is set by the municipality and reviewed every three years. For land it commonly runs at 60% to 70% of market. Applying 1.4% to the purchase price will overstate your bill.
3. Japan's 5-year line is measured from January 1 of the year you sell, not from the purchase anniversary. A property bought in March 2021 and sold in June 2026 has been held more than five calendar years in ordinary terms, but as of January 1 2026 the holding period was four years and roughly ten months, so the sale is taxed at the short-term 39.63% rate rather than 20.315%. Selling a few months later can be worth close to twenty points of tax.
4. Appoint a tax agent (納税管理人) before you leave Japan. Municipal and prefectural bills are sent to a Japanese address. Without a Japan-based representative to receive and settle them, notices bounce and arrears accrue against a property you believe is fully paid.
5. Expect the acquisition tax bill late. It arrives from the prefecture months after registration, by which point many buyers have closed their budget. Reductions for owner-occupied homes require filing within a set window.
6. Verify the parcel before requesting any assessment record. Japanese tax records are tied to the lot number (地番), which is not the postal address. Requesting an assessment against the wrong parcel returns the wrong value.

Sources and tools for working through the comparison:

• The prior-year fixed asset tax notice (固定資産税納税通知書) is the single most useful diligence document on the Japanese side. Ask the seller for it. It shows both the assessed value and the tax actually billed, which removes the guesswork from the recurring-cost estimate.
• Japan Property Research for identifying the lot number behind an address, so the correct assessment record can be requested, and for the city price map, which gives median sold prices, price per square metre, and three-year change by municipality from official transaction data.
• The National Tax Agency (国税庁) for capital gains treatment and the holding-period rules, and the municipal tax office (固定資産税課) for assessment records and valuation questions.
• The Land and Building Tax Act B.E. 2562 and the Thai Revenue Department and Land Department for the Thailand side, including current rate schedules and transfer costs.
• A licensed Japanese tax accountant (税理士) once rental income or any commercial use is involved, and particularly for non-resident owners, where withholding on rent and the annual filing obligation both apply.

Before committing, you want: the assessed value, the prior-year tax notice, an acquisition-tax estimate, a view on your intended holding period against the 5-year line, and a designated tax agent if you will not be resident in Japan.

FAQ

Can a Thai citizen own land in Japan? Yes, outright and in their own name. Japan places no nationality restriction on land or building ownership, and no quota applies. This is the substantive difference from Thailand, where the Land Code bars foreign land ownership entirely and condominium purchases are limited to a 49% share of a building's saleable floor area.

Is Japanese property tax higher than Thai property tax? For recurring annual tax, materially higher in most cases. Thailand exempts an owner-occupied first home on its first 50 million baht, so many Thai owners pay nothing annually. Japan charges 1.4% plus up to 0.3% on assessed value with no equivalent exemption, though residential land reductions cut the land portion substantially. For transaction costs at purchase the two are closer.

Do I pay tax in both countries? Japanese property tax and Japanese capital gains tax are owed in Japan regardless of your residence. Whether the same income is also assessable in Thailand depends on your Thai tax residency and on what you remit into Thailand. The Japan and Thailand double taxation agreement governs relief. This is a question for a qualified adviser in both jurisdictions, not one to settle from a guide.

What is the tax if I sell a Japanese property within 5 years? 39.63% on the gain, against 20.315% if held longer. The five years are counted as of January 1 of the year of sale, which frequently catches sellers who count from their purchase date.

Do I need to be in Japan to own property there? No, but you need a tax agent (納税管理人) resident in Japan to receive and pay municipal and prefectural tax bills on your behalf. Appoint one before you leave.
