Depreciation is one of the most frequently misunderstood parts of running a business in China. Foreign companies arriving from IFRS or US GAAP environments often assume they can keep depreciating assets the way they do at home, only to discover that Chinese tax law sets rigid minimum useful lives that may differ from their group accounting policy. Get it wrong and you risk rejected deductions, higher corporate income tax, and awkward questions during an audit. Get it right and depreciation becomes a predictable, lawful way to manage your taxable profit.
- China applies two parallel depreciation regimes: statutory book depreciation under CAS and minimum useful lives under CIT law.
- For tax, buildings use a 20-year life and electronic equipment a 3-year life as a legal minimum.
- Accelerated depreciation and one-time deductions exist but are restricted to qualifying assets and enterprises.
- Depreciation starts the month after an asset is put into use, never on the purchase date.
- Book-versus-tax differences must be tracked carefully, as they feed directly into annual reconciliation filings.
Why Depreciation Rules Matter in China
In China, depreciation is not a cosmetic accounting choice. It directly determines how much of an asset’s cost you may deduct from taxable income each year, which in turn drives your corporate income tax liability in China. A foreign-invested entity that depreciates a machine over five years when tax law requires a minimum of ten will have part of its deduction disallowed during the annual reconciliation, or “hui suan qing jiao.” Over a multi-year asset base, these differences can compound into a material tax exposure.
Depreciation also feeds your statutory financial statements. Because Chinese bookkeeping must follow the Chinese Accounting Standards (CAS) rather than IFRS, the figures your local team reports and the figures your group consolidation expects rarely match without adjustment. Understanding both sets of rules is the first step to a clean month-end close and a defensible annual audit in China.
Book Depreciation vs. Tax Depreciation
China effectively runs two depreciation systems side by side. Book depreciation follows CAS, which requires an entity to select a method that reflects the pattern in which the asset’s economic benefits are consumed. The straight-line method is overwhelmingly the norm, though other methods are permitted in principle.
Tax depreciation follows the Enterprise Income Tax (CIT) Law and its implementing regulations. Crucially, the CIT law prescribes minimum useful lives rather than fixed ones. You may not shorten a life below the statutory floor to accelerate deductions, although you are generally free to use a longer life if that is commercially justified. The gap between your book life and the tax-minimum life creates a timing difference that must be reconciled each year.
Statutory Minimum Useful Lives
The CIT implementing rules set out minimum depreciation lives for tax purposes by asset category. These are the most important numbers for a foreign company’s tax planning:
| Asset Category | Minimum Tax Life |
|---|---|
| Buildings and structures | 20 years |
| Aircraft, trains, ships, machinery, and other production equipment | 10 years |
| Appliances, tools, and furniture related to production and operation | 5 years |
| Means of transport other than aircraft, trains, and ships | 4 years |
| Electronic equipment | 3 years |
Two points trip up newcomers. First, “electronic equipment” covers computers, servers, and office electronics, which explains why tech and office-heavy operations can deduct these assets quickly. Second, land use rights are not depreciated at all; they are classified as intangible assets and amortized over the term of the right, typically 40 to 70 years depending on the use.
Depreciation Methods Allowed in China
The straight-line method is the default and, for most foreign companies, the only practical choice. The CIT law also recognizes the accelerated methods used in many Western jurisdictions, but their availability is limited. Before selecting anything other than straight-line, confirm that your asset genuinely qualifies, because the tax authority in your city will expect documentation justifying the choice.
Residual value is another area of confusion. Chinese tax practice generally accepts a reasonable residual value, and a common convention is to assume a low or zero residual for many asset classes, but this should be set consistently and defensibly rather than copied from an overseas policy without thought. Depreciation begins in the month following the month the asset is put into use, and it stops in the month following disposal or cessation of use.
Accelerated Depreciation and One-Time Deductions
China does offer faster write-offs, but they are targeted. Assets subject to rapid technological advancement or to continuous heavy vibration or high corrosion may qualify for accelerated depreciation, as may fixed assets of enterprises in certain promoted sectors. Separately, a long-running incentive allows newly purchased equipment and apparatus with a unit value of RMB 5 million or less to be deducted in full in the year of purchase for qualifying enterprises. This one-time deduction is a genuine cash-flow benefit, but eligibility, industry scope, and validity dates change, so it must be verified against current policy before you rely on it.
Because these incentives are elective, claiming them without checking eligibility can create the opposite problem: an over-claim that is reversed on audit, with interest and penalties attached. A disciplined approach is to treat every accelerated or one-time deduction as a decision that your finance team documents in writing at the time it is made.
Depreciation Compliance in Guangzhou and Shenzhen
Depreciation law is national, so the rules in Guangzhou, Shenzhen, Foshan, and Dongguan are identical to those in Beijing or Shanghai. What differs is enforcement posture. The tax bureaus in Guangzhou and Shenzhen, where Dan Young’s clients are concentrated, routinely cross-check fixed-asset registers against depreciation schedules during the annual reconciliation and during random inspections. A company operating across Guangdong must maintain one consistent depreciation policy and asset register, because inconsistent treatment between a Guangzhou entity and its Shenzhen branch is an easy audit trigger.
Working with a provider that understands both CAS reporting and CIT depreciation, such as our bookkeeping and audit service in China, helps ensure your monthly bookkeeping stays aligned with your tax position. If you are unsure whether your current provider is handling depreciation correctly, reviewing your choice of bookkeeping provider is a sensible starting point.
Frequently Asked Questions
What is the minimum depreciation life for a building in China?
For corporate income tax purposes, the minimum useful life for buildings and structures is 20 years. You may use a longer life if justified, but you cannot use a shorter one to accelerate tax deductions.
Can I depreciate computers over one year in China?
Electronic equipment carries a statutory minimum tax life of three years. Computers may qualify for a one-time deduction only if they fall under a current incentive for newly purchased equipment up to RMB 5 million and your enterprise meets the eligibility conditions, so always verify the policy before claiming it.
When does depreciation start for a fixed asset in China?
Depreciation begins in the month following the month in which the asset is put into use, not on the purchase or payment date. An asset placed into service in March, for example, begins depreciating in April.
Does China allow accelerated depreciation?
Yes, but on a limited basis. Accelerated methods are available for assets subject to rapid technological change or heavy vibration or corrosion, and for certain qualifying enterprises, alongside targeted one-time deduction incentives. Eligibility must be confirmed against current policy.
Are land use rights depreciated in China?
No. Land use rights are treated as intangible assets and amortized over the term of the right, typically 40 to 70 years, rather than depreciated as a fixed asset.
