When a business leases out factories, warehouses, office buildings, parking areas, or similar properties,
determining the correct depreciation period is essential as it directly affects
deductible expenses and Corporate Income Tax (CIT).

Da Nang Tax Department has provided clear guidance based on Circular 45/2013/TT-BTC as follows:

✅ 1. Depreciation is mandatory for leased fixed assets

According to Clause 5, Article 9 of Circular 45:

Enterprises leasing out fixed assets must calculate depreciation for those leased assets.

👉 This means depreciation cannot be suspended just because the asset is leased out.
Compliant depreciation remains a deductible expense for CIT purposes.

✅ 2. Depreciation must follow the time limits in Circular 45

Enterprises may decide their own depreciation period,
but it must fall within the minimum – maximum range stipulated in Appendix 1 of Circular 45.

Depreciation range – Group G (Buildings & Structures)

👉 When determining depreciation time, businesses should consider
actual useful life – economic efficiency – leasing plan
to ensure compliance and tax optimization.

✅ 3. Each component meeting the criteria = an independent fixed asset

If the construction includes multiple components, and each component meets the criteria of a fixed asset,
the business must depreciate each part separately, such as:

• 🏢 Office building → Permanent buildings
• 🏭 Factory building → Other buildings
• 🚗 Parking shelter → Canteens / rest areas / parking structures
• ⚙️ Auxiliary works (fences, internal roads, water tanks…) → Other structures

👉 Proper separation ensures an accurate representation of assets,
avoiding misclassification that may lead to tax risks during audits or inspections.
