What is 调整后计税基础?
在原始购入价格基础上，加上资本性改良支出、减去折旧摊销后的计税价值，用于计算资本利得税。UAE目前不征收资本利得税，但该概念在跨境投资税务规划中仍具参考价值。
Description
Adjusted basis is an accounting and tax concept that represents the 'cost' of your property for the purpose of calculating profit or loss when you sell. You start with the original purchase price (including acquisition costs), add the cost of capital improvements, and subtract any depreciation claimed. The difference between the sale price and your adjusted basis determines your gain or loss.
Original purchase price: AED 1,200,000. Acquisition costs (DLD, agent, legal): AED 90,000. Kitchen renovation: AED 80,000. Bathroom upgrade: AED 45,000. No depreciation claimed (UAE context). Adjusted basis = AED 1,415,000. If the property sells for AED 1,700,000, the gain is AED 285,000.
Capital improvements (renovations, extensions, system upgrades)
Acquisition costs (transfer fees, legal fees, agent commissions)
Special assessments for local improvements
Depreciation deductions (relevant in tax jurisdictions)
Insurance reimbursements for casualty losses
Casualty or theft losses previously deducted
Since the UAE historically had no capital gains tax on property, adjusted basis was less critical for tax planning. However, with the introduction of UAE corporate tax (9% on profits above AED 375,000) in 2023, companies holding real estate assets now need to track adjusted basis carefully. Individual investors still benefit from no capital gains tax on personal property sales, but maintaining records of improvements and acquisition costs is good practice for financial analysis.
公式
Adjusted Basis = Original Purchase Price + Acquisition Costs + Capital Improvements - Depreciation ClaimedHow to interpret
Tracking adjusted basis is good financial hygiene even in low-tax environments. It gives you an accurate picture of your true investment cost and the actual gain you would realize on sale, which matters for evaluating whether the investment has met its return objectives. Investors who add significant capital improvements to a property and fail to track them often underestimate their true return.
Capital improvements that increase adjusted basis include kitchen and bathroom renovations, floor replacements, central AC system upgrades, and structural work. Routine maintenance items such as painting, cleaning, and minor repairs do not adjust basis. Keeping receipts and a detailed capital expenditure log simplifies the calculation notably.
迪拜市场背景
While individuals in the UAE pay no capital gains tax on personal property sales, corporate entities holding real estate became subject to UAE corporate tax in June 2023. For those entities, adjusted basis is now directly relevant to calculating taxable gains. A property bought for AED 2 million with AED 300,000 in qualifying capital improvements has an adjusted basis of AED 2.3 million. If sold for AED 3 million, the taxable gain is AED 700,000, not AED 1 million.
Investors who hold multiple properties in a corporate structure should work with a UAE-qualified tax advisor to establish a proper cost-tracking system from acquisition. Reconstructing historical improvement costs after the fact is difficult and may result in a higher taxable gain than necessary because undocumented expenditures cannot be included in the adjusted basis calculation.
