Motor car depreciation under the Income Tax Act is one of the most valuable tax benefits available to business vehicle owners in India. In April 2026, understanding how Section 32 depreciation works, when Section 179 immediate depreciation applies, and how the two interact can save business owners lakhs in income tax over the lifetime of a vehicle. This guide covers every aspect of car depreciation from purchase to sale.

Depreciation on a motor car reduces your taxable business income each year by a percentage of the vehicle's cost. This tax shield is available to self-employed individuals, businesses, and companies that use cars for business purposes. The key requirement is demonstrable business use — personal-use cars do not qualify for depreciation deductions, though CarTax.online explains how partial business use can still yield partial benefits.

Section 32 Depreciation — The Standard Car Depreciation Rate

Under Section 32 of the Income Tax Act, motor cars used for business purposes qualify for depreciation on a written-down value basis. The standard rate of 15% per year applies to cars used in the course of business, whether for transport, client meetings, or delivery operations. The depreciation is calculated on the actual cost of the vehicle, including the purchase price, GST paid, and any improvements made.

For block-of-assets accounting, if a car is sold and a new one is purchased in the same asset block, the depreciation continues at the standard rate. The written-down value of the block carries forward. Additional depreciation of 20% was available under earlier Finance Act provisions for new plant and machinery — verify whether this remains applicable for Assessment Year 2026-27.

Section 179 — Immediate Full Depreciation for Qualifying Vehicles

Section 179 of the Income Tax Act provides a special provision allowing 100% depreciation deduction in the year of purchase for certain qualifying assets. For motor cars, Section 179 applies specifically to vehicles with engine capacity exceeding 1,800 cubic centimetres that are acquired for the purpose of hiring (such as taxi fleets or commercial rental vehicles).

Private business-use cars typically do not qualify for Section 179 and must use the standard Section 32 written-down value depreciation. However, if you operate a car rental business or commercial fleet, your vehicles may qualify for full Year 1 depreciation under this section, significantly accelerating the tax benefit compared to spreading 15% depreciation over multiple years.

Business Use Conditions and Documentation

Claiming motor car depreciation requires supporting documentation demonstrating genuine business use. Maintenance of a logbook recording business trips, client visits, and business-related travel is essential. For self-employed individuals, the logbook serves as evidence alongside invoices, contracts, and GST registrations that establish the business connection. Companies must maintain vehicle utilization records, fuel bills, and trip reports.

The income tax department scrutinises car depreciation claims heavily, particularly for high-value luxury vehicles. Vehicles with ex-showroom price above INR 25 lakh attract additional scrutiny. Maintaining contemporaneous records from the date of purchase — not retroactively reconstructed records — is critical for surviving a tax audit.

Frequently Asked Questions

How is motor car depreciation claimed under Income Tax Act Section 32?

Motor car depreciation under Section 32 of the Income Tax Act is available only when the car is used for business purposes. The standard depreciation rate is 15% per year on a written-down value basis. For cars acquired on or after August 1, 2024, the Finance Act 2025 revised the applicable rates — check current CBDT notifications for the latest percentage, as these are updated periodically.

What is Section 179 immediate depreciation for cars?

Section 179 of the Income Tax Act allows businesses to claim 100% depreciation on certain assets in the year of purchase instead of spreading it over years. Under Section 179, a motor car (used for business) with engine capacity above 1,800cc and used for hire — such as a taxi — may qualify for full depreciation in Year 1. Private business-use cars typically do not qualify for Section 179 and use the standard 15% written-down value rate.

Can I claim car depreciation if the car is used partly for personal purposes?

Depreciation on a motor car is allowable only to the extent the car is used for business purposes. If the car is used partly for personal and partly for business, only the proportion of business use qualifies for depreciation. The income tax department may ask for a logbook or usage records to verify the business-use percentage. If personal use exceeds 50%, depreciation claims may be disallowed entirely.

What are the depreciation rates for different car categories in 2026?

The Income Tax Act specifies different rates depending on car type. Motor cars not covered under Section 179 attract 15% depreciation on written-down value. Taxis and commercial vehicles used for hire may attract different rates. The additional depreciation of 20% (introduced in earlier years) was a time-bound provision — check current AY 2026-27 provisions for whether it remains available.

How does depreciation affect capital gains when selling a business-used car?

Depreciation reduces the car's written-down value each year. When sold, the difference between the sale price and written-down value is taxed as a capital gain. Short-term capital gains are added to your business income and taxed at slab rates. Long-term gains (for assets held more than 24 months) are taxed at 20% with indexation. Claiming maximum depreciation minimises your tax during ownership years but may create a larger capital gain on sale.
