Twenty Years, One Machine: Calcutta HC Settles Whether an ATM Is a “Computer” for Depreciation

Published 24 Sept 2026· By Finoscape Editorial Team· 6 min read

A bank that installs an ATM is not buying a vending machine that happens to dispense cash. It is buying a device that authenticates a card, queries a core banking server in real time, runs encryption and fraud-detection software, and updates a ledger — all before the cash tray even opens. Whether the Income-tax Act sees it that way, for depreciation purposes, has been an unsettled question since banks first began claiming the higher “computer” depreciation rate on their ATM networks in the early 2000s, rather than the lower general rate that applies to ordinary plant and machinery.

The Royal Bank of Scotland, N.V. found itself on the wrong side of that question when its return for Assessment Year 2003-04 came up for scrutiny. The Assessing Officer, the first appellate authority, and eventually the Income Tax Appellate Tribunal itself all took the same view: an ATM is not a “computer” within Item 2B of Appendix I to the Income-tax Rules, 1962 — it is banking hardware, taxed at the ordinary rate that applies to plant and machinery generally. The bank carried the question all the way to the Calcutta High Court, where it sat, as one of four substantial questions of law in a broader appeal that also touched on the tax treatment of interest payments under the India-Netherlands tax treaty, for the better part of two decades.

Sidebar: the appeal itself — ITA 699 of 2007 — was nearly as old as the assessment year it concerned. Two decades between an assessment order and its final resolution is an unusually long life for a single depreciation question, and a reminder of just how long a genuinely unsettled point of tax classification can stay open when nobody forces the issue to a final court.

On 22 September 2026, a Division Bench of Justices Rajarshi Bharadwaj and Uday Kumar ruled for the bank. The Court’s reasoning turned on a single, deceptively simple test: “the classification of an asset for depreciation purposes must be determined by its functional utility in the business of the assessee.” An ATM, the Bench found, is not defined by its exterior — a steel cabinet, a cash dispenser, a card slot — but by what it actually does: sophisticated, real-time data processing, running specialised software, connected over a network, functioning as the primary digital interface through which a banking transaction is executed. On that functional test, the Court held, “functional parity between an ATM and a computer is sufficient to warrant its inclusion” in the computer category — reversing the Tribunal and allowing the bank’s claim.

Why It Matters

Item 2B of Appendix I (now given effect through Rule 5 of the Income-tax Rules) has long carried a materially higher depreciation rate for “computers including computer software” than the general rate for plant and machinery — historically 60% against a much lower general rate under the block-of-assets scheme that applied for AY 2003-04, since rationalised (with effect from AY 2018-19) to the current 40% for computers against 15% for general plant and machinery. That gap is exactly why the classification question has real money attached to it, and exactly why it recurs: every few years, a new category of increasingly “smart” business equipment — ATMs in the early 2000s, EPOS terminals, specialised medical-imaging equipment, industrial control systems today — raises the same underlying question in a new form. This ruling doesn’t create a new rule; it reaffirms an existing one (the “functional utility” test used in earlier ATM-depreciation rulings from other Tribunals and High Courts over the years) at the level of a High Court, on facts that took two decades to reach final resolution.

Key Takeaways

The test for whether a piece of equipment qualifies as a “computer” for the higher Appendix I/Rule 5 depreciation rate is functional, not physical — what the device actually does in the business, not what it looks like or what it is colloquially called.
An ATM’s real-time data processing, specialised software, and network connectivity were held sufficient to bring it within the computer category, reversing the ITAT’s contrary view.
The higher computer depreciation rate today is 40% (post the AY 2018-19 rationalisation), against the general plant-and-machinery rate of 15% — the same underlying gap that made this two-decade-old dispute worth litigating in the first place.
The same functional-utility reasoning extends naturally to other “smart” equipment categories where the classification question hasn’t yet been tested — this ruling is a template for that argument, not a rule limited to ATMs specifically.

Practical Implications

Any business — not only banks — claiming depreciation on equipment that blurs the line between “machinery” and “computer” (point-of-sale terminals, embedded industrial controllers, specialised diagnostic or metering equipment with onboard processors) now has a High Court precedent squarely on point for the functional-utility argument, rather than relying only on Tribunal-level ATM rulings from other jurisdictions. Practitioners should document, contemporaneously, exactly what the equipment does — the data it processes, the software it runs, its network dependency — since that is precisely the evidentiary record this ruling shows a court will actually examine, not the invoice description or the accounting head under which the asset happens to sit.

Action Checklist

Review any client’s fixed-asset register for equipment currently depreciated at the general plant-and-machinery rate that performs genuine data-processing functions — this ruling is directly citable in reassessment or appeal proceedings on the point.
For new-generation “smart” equipment purchases, build the functional documentation (technical specifications, software dependency, network connectivity) into the asset file at the time of acquisition, not retrospectively at the time of a dispute.
Where an existing depreciation position already relies on the computer rate for similar equipment, this ruling strengthens rather than changes that position — no action needed beyond noting the precedent.

Relevant Sections

Section 32 of the Income-tax Act, 1961 (depreciation on tangible and intangible assets) read with Rule 5 of the Income-tax Rules, 1962 and Item 2B, Appendix I (classification and rate for “computers including computer software”).

Relevant Rules

Rule 5, Income-tax Rules, 1962; Appendix I (rates of depreciation), Item 2B.

Relevant Notifications

None — this is a judicial ruling on an existing rule, not a new notification. Calcutta High Court judgment dated 22 September 2026 in The Royal Bank of Scotland, N.V. v. Director of Income Tax (International Taxation), Kolkata, ITA 699 of 2007.

FAQs

Q: Does this ruling change the current depreciation rate for computers?
A: No. It settles a classification question — whether a particular device counts as a “computer” for the existing rate — not the rate itself, which was last rationalised for AY 2018-19 onward (40% for computers, 15% for general plant and machinery).

Q: Can this reasoning be used for equipment other than ATMs?
A: The Court’s own language is functional, not ATM-specific — “classification… must be determined by its functional utility” — so the reasoning is available as precedent for any equipment genuinely performing data-processing functions, though each case still turns on its own facts.
