Electric Vehicle Depreciation Rate: What Fleets Claim Vs What The Market Pays

Two different numbers get called the electric vehicle depreciation rate, and conflating them is how EV business cases go wrong. This one is for fleet owners, finance heads and CFOs deciding how to capitalise an EV purchase — the people who sign the asset schedule, not the people trading in a car.

The first is the book rate: what the income-tax rules let a business write down each year on a vehicle it owns and uses for that business. It is fixed by statute, whether or not the vehicle holds its value. The second is market depreciation: what a three-year-old fleet EV actually fetches. Neither number moves the other.

The book rate pushes cash into years one to three; the resale number decides the far end of the hold. This post covers the tax mechanics only — cost structure lives in our EV fleet TCO breakdown, the return case in the fleet ROI analysis.

The Electric Vehicle Depreciation Rate Your Books Can Claim

From 1 April 2026 the governing law is the Income-tax Act, 2025, which replaced the 1961 Act for tax year 2026-27 (assessment year 2027-28). Depreciation is section 33; the rates sit in Appendix I to the Income-tax Rules, 2026, read with rule 25. The mechanics are unchanged — you depreciate the block of assets a vehicle joins, not the vehicle. Three entries can catch a fleet vehicle; the gap between them is the story.

The 40% line is what changes fleet economics, and unlike the 45% and 30% entries from the August 2019 window, it carries no acquisition cut-off. Note where it sits, though — inside the renewable energy devices group, beside solar collectors and biogas engines. Put that classification to your advisor in writing before you model on it.

Two provisions that decide what you actually get

Section 33(4) halves the deduction where an asset is acquired during the tax year and put to use for fewer than 180 days in it. Rule 25(2) caps depreciation at 40% of written down value for domestic companies in the concessional regimes — a real constraint elsewhere, free here, because 40% is already the rate.

Why The Tax Shield Is Front-Loaded

Take 50 electric delivery vans in Delhi at ₹12 lakh each: ₹6 crore in one block, all commissioned before the 180-day line. Written down value compounds downward, so the deduction is largest in year one.

Illustrative: 50 vans at ₹12 lakh, one block, full-year rate in year one.

That is ₹4.70 crore, or 78% of cost, deducted inside three years. Run the same fleet at 15% and the three-year total is ₹2.32 crore — 39%. The ₹2.4 crore difference is worth roughly ₹60 lakh of tax at a 25% effective rate, landing while the loan is still being serviced and charger capital is still being absorbed.

Two cautions. This is a timing benefit, not a permanent one: the same cost is eventually deducted either way, so what you buy is the present value of moving deductions forward. Quantify it as an NPV, not a saving. And delivery dates are a tax decision — a van commissioned after the 180-day line earns 20%, not 40%, moving ₹1.2 crore of deduction out a full year.

Lease An EV And You Claim No Depreciation At All

The electric vehicle depreciation rate belongs to whoever owns the asset. Section 33(1) allows depreciation to the person who owns it and uses it wholly and exclusively for business. On an operating lease the lessor owns the vehicle, claims the 40%, and prices that benefit into your rental. You deduct the rental as an operating expense instead — a good deduction, but spread evenly. Anyone weighing EV fleet leasing against ownership starts here.

What matters is who can use the shield, because it is worth nothing to a company with no taxable profit. Thin profits leave the allowance parked as unabsorbed depreciation; section 33(11) carries it forward, so it is deferred rather than lost. A lessor with steady profits turns the same allowance into cash now, which makes it the more efficient owner. Ask for the residual and the tax assumption behind any quote — a lessor that will not show them is charging you for a benefit you cannot audit. The decision itself sits in our lease-versus-buy comparison.

Market Depreciation: The Battery Is The Asset That Moves

Book value falls on a schedule; resale value falls on a physics-and-sentiment curve, and on an EV the two diverge faster than on a diesel. Chassis and drivetrain age with kilometres, predictably. The pack ages with charge cycles, depth of discharge and heat — so two identical vans bought the same week can diverge visibly by year three.

The direction of that divergence usually surprises operators. After three full years at 40%, book value is 21.6% of original cost — normally below what a documented three-year-old fleet EV still inside its pack warranty will fetch. Under the block method there is no per-vehicle gain to book: proceeds come off the block’s written down value. Stop treating book value as a proxy for what the asset is worth.

The residual is an input to source from live quotes, not assume, and the spread between two identical vans is set by documented state of health — which is why the retire-or-redeploy call belongs with battery state of health data rather than age, and why fleet reporting turns a resale haggle into an evidenced price.

What To Keep On File So The Claim Survives Scrutiny

A 40% claim on a vehicle block is a visible position. None of the documentation is exotic; claims come apart because nobody owns the file.

• Proof the vehicle is electrically operated — invoice and registration certificate showing the powertrain, since the entire rate difference turns on that classification.
• Date put to use, not date of purchase — the 180-day test runs on commissioning. Keep the handover note and the first trip record.
• Evidence of wholly and exclusively business use — section 33(3)(b) lets an assessing officer restrict the deduction proportionately. Trip logs end that argument.
• A block-wise fixed asset register reconciling to the tax computation: additions, disposals, insurance recoveries.
• A disposal trail — sale invoice, buyer, proceeds, and the adjustment made to the block.

Almost all of it is data a fleet already generates and then loses. A fleet operating system like YoMobility, logging trips, odometer readings and charging sessions per vehicle, is the cheapest audit evidence a finance team will assemble. Keep the depreciation position and the resale position as two separate lines, exactly as the law keeps them.
