In apartment and condominium management, understanding depreciation and statutory useful life is fundamental to tax planning and investment decisions. When it is recorded correctly in the annual tax return, the tax burden can be reduced substantially.
What Is Depreciation? Understanding the Basics in Rental Property Management
Depreciation is an accounting treatment in which fixed assets such as buildings and equipment are not expensed in full at the time of purchase, but are recognized as expenses in installments over their statutory useful life. Land is not subject to depreciation because it is considered an asset whose value does not decline over time. In rental property management, only the building portion is eligible.
Bulk Depreciation and the Special Rule for Low-Value Depreciable Assets
Assets with an acquisition cost of at least 100,000 yen but less than 200,000 yen can be depreciated over three years as bulk-depreciation assets, with the added benefit that they are not subject to fixed asset tax. In addition, blue-return taxpayers can use the “special rule for low-value depreciable assets,” which allows assets costing less than 300,000 yen to be fully expensed in the year of purchase (up to a total of 3 million yen per year). This can deliver significant tax savings in years with strong earnings.
What Is the Statutory Useful Life of an Apartment Building?
The statutory useful life varies depending on the building structure and serves as an important benchmark for investment decisions.
- Wood-frame apartment building: 22 years (including conventional wood-frame construction and wood-based prefabricated methods)
- Light-gauge steel frame (structural material 3 mm or less): 19 years
- Light-gauge steel frame (structural material over 3 mm and up to 4 mm): 27 years
What Risks Arise When the Statutory Useful Life Is Exceeded?
Risk of Becoming Ineligible for Financing
Financial institutions generally do not provide financing for properties that have exceeded their statutory useful life. For wood-frame properties older than 22 years, prospective buyers may also find it difficult to obtain financing, which makes a sale more challenging. Even when purchasing a newly built property, it is important to consider the possibility of future constraints at the time of sale.
Risk of No Longer Being Able to Claim Depreciation
Once the useful life is exceeded, the expense can no longer be recorded, which means taxable income increases and the amount of tax due also rises. For example, if a 50 million yen wood-frame apartment building is depreciated using the straight-line method, 2.3 million yen per year (50 million × 0.046) can be recorded as an expense for 22 years. After that period ends, this tax-saving benefit disappears.

Frequently Asked Questions (FAQ)
Q. Do I have to record depreciation every year?
A. Yes. For individual real estate income, depreciation is mandatory, so it must be recorded every year. Even if it is not recorded in a given year, the unclaimed amount cannot be carried forward to the following year.
Q. What useful life applies if I purchase a used apartment building?
A. If the statutory useful life has already been exceeded, you can use the simplified useful life calculated as “statutory useful life × 20%.” If the property is still within its statutory useful life, you can use the simplified formula “(useful life − elapsed years) + elapsed years × 20%.”
Q. Can land costs be depreciated?
A. No. Land is treated in accounting as an asset whose value does not change, so only the building portion is subject to depreciation.
Q. Can I continue using a property even after it exceeds its statutory useful life?
A. Physically, continued use is possible, but depreciation can no longer be claimed and the tax-saving effect is lost. It may also become disadvantageous when seeking financing or selling the property, so it is important to plan appropriate maintenance and an exit strategy in advance.
