Key Takeaways
- Land is generally not depreciable, while buildings, machinery, vehicles, computers, and office equipment usually are.
- Straight-line depreciation is the most common method, although accelerated and usage-based methods may also be available.
- Tax useful lives should follow Taiwan’s official Table of Service Life of Fixed Assets.
- Costs required to bring an asset into use, such as freight, installation, and testing, are normally capitalized.
- Assets with a service life of less than two years may qualify for immediate deduction.
- Clear asset registers and disposal evidence are often as important as the calculation itself.
Taiwan businesses generally recover the cost of qualifying fixed assets through depreciation over the assets’ tax useful lives. The deduction depends on classification, cost, salvage value, method, useful life, business use, and records.
What Is Fixed Asset Depreciation in Taiwan?
Fixed asset depreciation allocates the cost of a long-term business asset across the periods in which it helps generate income. A company that acquires machinery, vehicles, computers, furniture, or buildings generally cannot deduct the full price immediately. Instead, the expenditure is capitalized and deducted over an applicable useful life.
For example, machinery costing NT$3,100,000 with a salvage value of NT$100,000 has a depreciable amount of NT$3,000,000. If the approved useful life is 10 years, annual straight-line depreciation is generally NT$300,000.
What Rules Govern Tax Depreciation?
Taiwan’s depreciation framework is based mainly on the Income Tax Act, related enforcement regulations, Ministry of Finance guidance, and the Table of Service Life of Fixed Assets. The official table classifies assets and assigns standard service lives that generally operate as minimum tax periods.
Financial reporting may use different estimates, but tax-return depreciation must comply with tax rules. Shortening a useful life or changing a method solely to accelerate deductions may invite scrutiny unless legally supportable.
Which Assets Can Be Depreciated?
An asset generally qualifies when it supports taxable business income, provides multi-period benefits, has a measurable cost, and is subject to wear or obsolescence. Land is usually excluded because it does not normally have a finite useful life. When land and a building are purchased together, the price should be allocated so that only the building and qualifying improvements are depreciated.
How Is the Depreciable Cost Calculated?
The tax basis may include more than the invoice price. Directly attributable costs needed to bring the asset to its intended location and working condition are usually capitalized. Common examples include freight, import duties, installation, testing, engineering fees, construction labor, and professional charges.
Routine operating costs are normally expensed. At acquisition, retain the contract, invoice, payment record, specifications, installation report, and date placed in service.
How Is Salvage Value Applied?
Salvage value is the estimated residual value at the end of an asset’s useful life. The basic formula is: Depreciable amount = asset cost − salvage value. Residual values should be reasonable and consistent, especially for assets with active resale markets.
What Depreciation Methods Are Available?
- Straight-line: Allocates an equal amount each year. It is transparent, predictable, and easy to reconcile.
- Declining-balance: Applies a fixed percentage to the remaining book value, creating higher deductions in earlier years.
- Sum-of-the-years’-digits: Also accelerates depreciation by assigning a larger share to the early years.
- Units-of-production: Links depreciation to actual output and suits equipment whose wear follows production volume.
- Working-hours: Uses operating time and may fit generators, heavy machinery, or other hour-driven assets.
What Are the Useful Lives of Common Assets?
The exact life depends on the category in the official service-life table. Representative periods commonly encountered are shown below. These figures are illustrative; actual classification depends on function and use.

How Are Short-Life Assets, Repairs, and Improvements Treated?
Assets with a service life of less than two years may qualify for immediate deduction in the year of acquisition or completion. Low price alone is insufficient; an item useful for several years may still require capitalization.
Routine repairs generally maintain an asset’s existing condition and may be deducted currently. Expenditure should usually be capitalized when it extends useful life, raises capacity, improves efficiency, replaces a major component, or creates benefits beyond the current year. Substance matters more than invoice wording.
How Are Leasehold Improvements and Disposals Handled?
Leasehold improvements include partitions, flooring, wiring, plumbing, and renovations made to leased property. Their depreciation period is often linked to the lease term because the tenant’s right to use them may end when the lease expires. Include renewal periods only when reasonably supportable.
When an asset is sold, sale proceeds are compared with the remaining tax book value to determine a gain or loss. Early scrapping requires persuasive evidence, such as disposal approvals, photographs, recycling receipts, destruction certificates, insurance records, or tax-authority approval where required. An accounting write-off alone may be insufficient.
How Does Tax Depreciation Differ From Accounting Depreciation?
Accounting estimates may differ because tax depreciation is more prescriptive. Differences may arise from useful lives, salvage values, commencement dates, methods, impairments, revaluations, and non-deductible costs. Maintain separate accounting and tax schedules when necessary.
What Records Should Businesses Maintain?
A reliable fixed asset register should record the asset description, identification number, location, acquisition date, date placed in service, original cost, capitalized ancillary costs, salvage value, depreciation method, accounting and tax useful lives, accumulated depreciation, remaining tax value, and disposal details.
The register should reconcile with invoices, the ledger, financial statements, and the tax return. In audits, weak documentation often matters more than arithmetic. Common risks include depreciating land, using unsupported lives, omitting salvage value, expensing capital improvements, depreciating assets before they are operational, and claiming unsupported scrapping losses.
Conclusion
Taiwan’s fixed asset depreciation rules require careful classification, accepted methods, appropriate service lives, reasonable salvage values, and complete documentation. Straight-line depreciation remains the most practical method for many companies, but the correct treatment depends on the asset’s nature and statutory category. A disciplined capitalization policy and complete asset register support deductions, reduce audit risk, and improve tax filings.
