Commercial Property Depreciation Explained: Meaning, Years & Tax Benefits (2026)

Buying a commercial property comes with more than just rental income and appreciation. Tax benefits such as depreciation also strengthen the overall investment case, alongside the other advantages covered in the top 10 reasons to invest in commercial property.  But unlike some countries where depreciation follows a fixed number of years, India's tax rules work differently, and understanding how the rate, the calculation, and the ownership conditions actually work can make a meaningful difference to your after-tax returns. Here's a clear breakdown of what it means, how it's calculated, and what it's worth to you. 

Commercial property depreciation is an annual deduction that lets a business or professional reduce their taxable income by accounting for the reduction in value of an office, warehouse, retail space, or other commercial building used in their trade.

The deduction is allowed under Section 32 of the Income Tax Act, 1961 (Section 33 under the new Income Tax Act 2025, effective FY 2026-27, with the same rates and rules carried forward). It applies only to the built-up structure - not to the land the building stands on, since land does not wear out with use.

• The property must be owned, wholly or partly, by the person claiming depreciation
  
  
• The property must be used for business or professional purposes during the relevant financial year
  
  
• Depreciation is claimed on the block of assets, not on each individual building separately

Many people search for commercial property depreciation years expecting a fixed write-off period, like the 39-year straight-line schedule used in some other countries. India's Income Tax Act doesn't work that way. Depreciation is calculated on the Written Down Value method, which applies a fixed percentage to the reducing balance every year, so the deduction shrinks gradually instead of following a set number of years. 

1. Under WDV, a 10% rate reduces the block value by 10% of the remaining balance each year, not 10% of the original cost
   
   
2. This means the deduction amount is highest in the early years and gets smaller over time
   
   
3. For companies following the Companies Act, 2013 (used for accounting depreciation, not tax), the useful life of a commercial building is
   generally set at 60 years for RCC structures and 30 years for non-RCC structures - this is separate from the income tax treatment.
   

The standard property depreciation rate for a non-residential (commercial) building is 10% on WDV, one of the higher building rates prescribed under the Income Tax Rules.

• Commercial or non-residential buildings: 10%
  
  
• Residential buildings (let out or used for staff housing): 5%
  
  
• Purely temporary structures (wooden, tin-shed type): 40%
  
  
• Furniture and fittings inside a commercial property: 10%

These rates apply uniformly across office buildings, warehouses, retail showrooms, and other commercial structures, regardless of city or state.

Depreciation is worked out by applying the prescribed rate to the WDV of the block of assets at the start of the year, plus any additions, minus any deletions.

The formula is straightforward once the opening WDV (Written Down Value) is known.

Depreciation for the year = (Opening WDV + cost of additions during the year − sale value of assets sold) × prescribed rate.

• If a commercial building worth ₹1 crore is purchased and used for more than 180 days in the year, the full 10% rate applies, giving a deduction of ₹10 lakh
  
  
• If the same building is put to use for less than 180 days, only 50% of the normal rate applies, so the first-year deduction is limited to 5%, or ₹5 lakh
  
  
• In year two, depreciation is calculated on the new WDV (original cost minus year-one depreciation), not on the original purchase price

This declining-balance approach is why early years of ownership offer a larger deduction than later years.

Depreciation directly lowers taxable business income, which reduces the tax payable without requiring any additional cash outflow in that year.

1. It is a non-cash expense, meaning the deduction is claimed without any real spending during the year it is claimed
   
   
2. It can be carried forward indefinitely if the business has insufficient profit to absorb it in a given year, unlike some other deductions with time limits
   
   
3. Additional depreciation of 20% is available on new plant and machinery used in manufacturing, though this does not apply to the building itself
   
   
4. For businesses holding warehousing or office assets long-term, consistent depreciation claims improve after-tax cash flow year on year

For owners of a pre-leased commercial property, depreciation can support better after-tax returns by reducing taxable business income while the property continues to generate regular rental income. 

Certain conditions must be met before a business can claim depreciation on a commercial property, and missing any of them can lead to disallowance during assessment.

Ownership and business use are the two non-negotiable conditions. The claimant must be the owner (full or part) of the property, and the property must actually be used for business or professional activity during the year, not merely held as an investment.

1. Depreciation cannot be claimed on land value under any circumstances, only on the constructed portion
   
   
2. Assets are grouped into a "block," so individual buildings within the same rate category are depreciated together, not tracked separately
   
   
3. If a property is used for less than 180 days in the year of purchase, only half the normal rate applies for that year
   
   
4. If the entire block of assets is sold or the block ceases to exist, any resulting short-term capital gain or loss is adjusted accordingly

Commercial property depreciation allows business owners to claim a 10% annual deduction on the Written Down Value of a commercial building, reducing taxable income year after year without any cash outflow. Since the deduction follows a declining-balance method rather than a fixed number of years, the benefit is largest in the early years of ownership and gradually tapers off. Understanding the applicable rate, the 180-day rule, and the block-of-assets structure helps businesses and property investors plan purchases and claim the full tax benefit they are entitled to.
