Japan Housing Loan Tax Deduction for Foreign Property Owners

Buying a home in Japan is a significant financial commitment — but the Japanese government offers a powerful incentive to help ease the burden: the Housing Loan Tax Deduction (住宅借入金等特別控除, Jutaku Shakkin-tō Tokubetsu Kōjo). Good news for foreign residents: you are eligible for this deduction regardless of your nationality, as long as you meet the standard residency and financial criteria. This guide breaks down everything you need to know about claiming this valuable tax benefit as a foreign property owner in Japan.

If you're still in the early stages of your property journey, check out our Complete Guide to Buying Property in Japan as a Foreigner and our dedicated article on Mortgages and Home Loans for Foreigners in Japan before diving into the tax deduction specifics.

What Is the Japan Housing Loan Tax Deduction?

The Housing Loan Tax Deduction is a tax credit that allows homeowners to deduct 0.7% of their outstanding mortgage balance at the end of each year from their income tax (and partially from the following year's inhabitant tax, if the income tax deduction exceeds the income tax owed). This deduction applies for up to 13 years for newly built homes and up to 10–13 years for second-hand homes, depending on property type and certification.

This is not a deduction from income — it is a direct credit against your tax liability, meaning it reduces the actual tax you owe yen-for-yen. For many homeowners, this can result in a refund of tens of thousands to hundreds of thousands of yen per year.

Are Foreigners Eligible for the Housing Loan Tax Deduction?

Yes — foreigners residing in Japan can claim the housing loan tax deduction, regardless of nationality. The key requirement is that you are a tax resident of Japan (i.e., you have a registered address in Japan and pay Japanese income tax). Your visa status, country of origin, or years of residence do not disqualify you.

The tax credit is available to:

• Foreign nationals with permanent residency
• Foreign nationals on work visas (Engineer/Specialist in Humanities, Highly Skilled Professional, etc.)
• Spouses on dependent visas who are co-borrowers
• Long-term residents on other visa categories

The main practical challenge for foreigners is not the tax side — it is securing the mortgage in the first place. Without permanent residency, banks apply stricter lending criteria. Read more about this in our guide on Mortgages and Home Loans for Foreigners in Japan.

According to Ichinose Tax Accountant Office, which specializes in expat tax matters in Japan, foreigners residing in Japan are fully entitled to housing tax credits provided they fulfill the eligibility conditions — there is no nationality-based restriction.

Eligibility Requirements in Detail

To qualify for the Housing Loan Tax Deduction, you must satisfy ALL of the following conditions:

1. Residency and Occupancy

• You must move into the property within 6 months of purchasing or completing construction
• You must continue living there as your primary residence throughout the year you claim the deduction
• You must be a tax resident of Japan (住民登録 is registered at your address)

2. Property Requirements

• Minimum floor area: 50 square meters (exceptions: 40 sq m minimum if your total income is 10 million yen or less)
• Must be located in Japan (overseas properties do not qualify)
• For second-hand homes: must pass a seismic safety inspection or be newly renovated to meet standards (homes built before 1981 need special certification)

3. Loan Requirements

• The loan must have a minimum repayment period of 10 years
• Must be a formal mortgage from a recognized financial institution (personal loans from family members do not qualify)
• Must be for the purpose of purchasing, building, or significantly renovating the property

4. Income Limit

• Your total annual income must not exceed 20 million yen in the year you claim the deduction

5. No Recent Property Sale with Special Deductions

• If you sold a previous home and claimed a capital gains exclusion within the past 2–3 years, you may be temporarily ineligible

How Much Can You Save? Maximum Loan Amounts and Deduction Calculations

The deduction is calculated as 0.7% of your outstanding loan balance at December 31st each year. The maximum eligible loan balance depends on the property type and certification:

2026 Update: The maximum eligible loan amount for second-hand homes certified under Long-Term Excellent Housing or Low-Carbon standards is being raised from 30 million to 35 million yen (and up to 45 million yen for young couples and households with children). The deduction period for used homes is also being extended to a maximum of 13 years.

Example Calculation

If you purchase a standard energy-efficiency-compliant home and your year-end mortgage balance is 35 million yen:

• Eligible balance: 35 million yen (capped at 40 million yen — full balance qualifies)
• Annual deduction: 35,000,000 × 0.7% = 245,000 yen
• Over 13 years (if balance decreases each year, total savings): roughly 2.5–3 million yen

How to Apply: Step-by-Step for the First Year

The most important thing to understand is that the first year requires a full income tax return (確定申告) filed at your local tax office. Subsequent years (from the second year onward) can be handled automatically through your employer's year-end tax adjustment (年末調整), if you are a salaried employee.

Year 1: File a Tax Return

1. Gather your documents (list below)
2. Visit your local tax office (税務署) between mid-February and mid-March following the year you moved in
3. File your tax return using the Housing Loan Deduction calculation sheet included in the official tax forms
4. Receive your refund by direct bank transfer (typically within 1–2 months)

Documents Required for Year 1

Year 2 Onward: Year-End Tax Adjustment (Salaried Employees)

From the second year, your employer can apply the housing loan deduction automatically through the year-end tax adjustment process. You will receive a notice from the tax office specifying the amount to claim each year. Simply submit this notice along with your annual bank balance certificate to your HR/payroll department.

Self-employed or freelance residents must continue filing a full tax return (確定申告) each year.

Practical Tips for Foreign Residents Claiming the Deduction

1. Make Sure Your Address Is Properly Registered

Your 住民票 (resident registration) must list the property as your primary address. If you buy a property but maintain a different registered address, you will not qualify.

2. Confirm Your Loan Qualifies

Not all financing arrangements qualify. The loan must be from a recognized financial institution with a repayment period of at least 10 years. Short-term bridge loans, family loans, or company loans typically do not qualify.

3. Get Your Year-End Balance Certificate from Your Bank

Japanese banks issue a 残高証明書 (balance certificate) in October or November each year. This document shows your outstanding loan balance as of December 31 and is essential for the deduction calculation. Keep this document — you will need it every year.

4. Consult a Tax Accountant (税理士) Who Speaks English

Japan's tax forms can be challenging in Japanese. Many expats benefit from hiring a bilingual tax accountant (税理士), especially for the first year. The Tokyo Portfolio guide on housing loan tax deductions is also a useful English-language resource.

5. Watch Out for the Used Home Certification Requirement

If you are buying a second-hand (中古) home built before 1981, you will need an inspection report confirming the building meets current seismic standards, or have the building inspected and certified. Without this, you may not qualify for the deduction on a pre-1981 property.

6. Do Not Confuse the Deduction with the Inhabitant Tax Reduction

The housing loan deduction is primarily applied against income tax. If your income tax is lower than the deduction amount, up to 97,500 yen (or 5% of the previous year's inhabitant tax base, whichever is lower) can be applied against your inhabitant tax as well.

Alternative: Special Deduction for Certified Housing Without a Loan

If you purchase a certified long-term quality, low-carbon, or energy-efficient home without taking out a housing loan, you may be eligible for a separate one-time tax credit:

• Maximum credit: 650,000 yen (for certified long-term excellent housing)
• Income limit: 30 million yen (higher than the loan-based deduction)
• No loan required: This credit is available to cash buyers

You cannot claim both this credit and the housing loan tax deduction simultaneously — you must choose one. For cash buyers of high-quality certified homes, this alternative is worth considering.

Mortgage Deduction and Leaving Japan

One concern many foreign property owners have is: what happens to the deduction if I leave Japan?

If you move out of Japan during the deduction period:

• The deduction stops from the year you are no longer a resident for tax purposes
• If you rent out the property while abroad, the deduction is also suspended
• If you return to Japan and resume living in the property, you may be able to resume claiming the deduction (within the original 13-year window)

This is an important consideration for foreigners on fixed-term visa assignments. Planning your property timeline in relation to your anticipated residency period can help maximize the benefit.

Summary

The Japan Housing Loan Tax Deduction is one of the most valuable financial benefits available to homeowners in Japan — and as a foreign resident, you are fully eligible to claim it. The key points to remember:

• 0.7% of your year-end mortgage balance is deducted from your income tax annually
• Available for up to 13 years for new homes, 10–13 years for used homes
• Open to all foreign residents who pay Japanese income tax
• Requires filing a full tax return in Year 1; your employer can handle it from Year 2

• Consult a bilingual tax accountant for the first filing to ensure accuracy

With potential savings of several million yen over the deduction period, taking the time to properly claim this benefit is well worth the effort.
