Income Tax
Tax Depreciation in Nepal — Rates, Asset Classes & Calculation
Applicable Income Year: FY 2083/84
Primary law: Income Tax Act, 2058 — Section 19 and Schedule 2 Current-year overlay: Finance Act 2083
For Nepal income-tax purposes, depreciation is calculated under Section 19 and Schedule 2 of the Income Tax Act, not by simply using the depreciation expense shown in the financial statements.
The principal tax depreciation classes are:
| Class | Main assets | Normal rate |
|---|---|---|
| A | Buildings, structures and similar permanent structures | 5% |
| B | Computers, data-processing equipment, furniture, fixtures and office equipment | 25% |
| C | Automobiles, buses and minibuses | 20% |
| D | Construction/excavation equipment and depreciable assets not otherwise classified | 15% |
| E | Intangible depreciable property | Based on useful life |
IRD's published Schedule 2 confirms the A–E classification, while the statutory Schedule specifies rates of 5%, 25%, 20% and 15% for Classes A–D respectively.
1. Eligibility and accounting differences
Accounting Depreciation vs Tax Depreciation
They are different computations.
Accounting depreciation
Usually depends on:
accounting standard;
estimated useful life;
residual value;
depreciation method;
impairment;
management estimates.
Tax depreciation
Depends on:
Income Tax Act;
Schedule 2 asset class;
tax depreciation pool;
statutory rate;
date/period of addition;
disposal proceeds;
special tax provisions.
Therefore:
Accounting depreciation should not automatically be claimed as tax depreciation.
When preparing an income-tax reconciliation, accounting depreciation is generally adjusted and the allowable Schedule 2 depreciation is calculated separately.
When Can Tax Depreciation Be Claimed?
Section 19 applies where a person:
owns the depreciable property; and
uses it in deriving income from a business or investment.
IRD's published Act expressly links depreciation to depreciable property owned and used in earning business or investment income.
So the basic test is: Ownership
Use in taxable business/investment
Depreciable property = potential Schedule 2 deduction.
2. Tax asset classes
Class A — Buildings & Permanent Structures
Examples may include:
office building;
factory building;
warehouse;
permanent structural works.
Normal depreciation rate: 5%
Land itself should not simply be put into Class A merely because a building stands on it.
The land and building components should be properly distinguished.
Class B — Computers, Furniture & Office Equipment
Examples:
desktop computers;
laptops;
servers;
printers;
data-processing equipment;
furniture;
fixtures;
office equipment.
Normal depreciation rate: 25%
This is usually the most common pool for professional firms and office-based businesses.
Class C — Motor Vehicles
Includes specified:
automobiles;
buses;
minibuses.
Normal depreciation rate: 20%
Vehicle classification should be based on the statutory class rather than an accounting fixed-asset category alone.
Class D — Machinery and Other Assets
Includes:
construction equipment;
excavation equipment;
machinery not otherwise specifically included;
other depreciable assets not falling into A, B, C or E.
Normal depreciation rate: 15%
This class can contain a broad variety of operational assets.
Class E — Intangible Property
Class E covers depreciable intangible property.
Unlike Classes A–D, Class E assets are generally maintained separately rather than combined into one common pool.
The depreciation rate is derived from the useful life of the intangible, using the Schedule 2 method.
Examples may include qualifying:
licences;
rights;
contractual intangible assets;
other depreciable intangible property.
Whether purchased software belongs in B, D or E should be determined from the nature of the expenditure rather than applying a blanket rule.
3. Pools, addition timing and examples
Pool System for Classes A–D
Classes A, B, C and D operate broadly on a pool basis.
Assets falling into the same class are grouped together.
The annual computation is conceptually: Opening tax pool
eligible additions
−
disposal proceeds/incomings = depreciation base
×
applicable rate = tax depreciation
This is different from calculating depreciation asset-by-asset in the accounting fixed-asset register.
First-Year Addition Rule
Schedule 2 section 2(5) uses the later of the time the asset is included in its statutory depreciation pool and the time its acquisition cost is incurred. Ownership, qualifying use and the relevant pool conditions must therefore be established before choosing a timing factor.
For that relevant date, the current-year addition is 3/3 of cost for Shrawan–Poush, 2/3 for Magh–Chaitra, and 1/3 for Baisakh–Ashadh. The remaining cost enters the following income year, subject to the statutory pool conditions. A purchase invoice date alone does not determine the factor where the later statutory event falls in another period.
Example — Computer Purchased in Jestha
Computer cost: NPR 300,000
Class: B
Purchase/use period: Baisakh–Ashad
Initial tax-base addition: NPR 300,000 × 1/3 = NPR 100,000
Normal Class B rate: 25%
Indicative first-year depreciation: NPR 100,000 × 25% = NPR 25,000
The remaining portion of cost is dealt with under Schedule 2 in the following income year.
Example — Existing Class B Pool
Opening Class B tax pool after prior-year treatment: NPR 800,000
Eligible current-year addition: NPR 300,000
Disposal proceeds: NPR 100,000
Simplified base: NPR 800,000
NPR 300,000
− NPR 100,000
= NPR 1,000,000
Depreciation: NPR 1,000,000 × 25%
= NPR 250,000
The actual computation must apply the Schedule 2 addition timing rules where the NPR 300,000 represents a current-year purchase.
4. Disposals and small pools
Disposal of Depreciable Assets
Tax treatment does not end when an asset is sold.
Schedule 2 adjusts the depreciation pool for amounts derived from disposal.
Depending upon the pool and disposal amount, the result can include:
reduction of the tax pool;
balancing income;
terminal deduction.
The statutory Schedule specifically deals with income or deduction where disposal proceeds differ from the remaining depreciation base.
Therefore the sale of a fully or partly depreciated asset should never simply be posted to:
“Profit on Sale of Fixed Asset”
and copied directly into the tax return.
A separate tax calculation is required.
Small Remaining Pool
Where the remaining Class A–D depreciation base after depreciation falls below the statutory threshold of NPR 2,000, Schedule 2 permits the remaining amount to be written off as additional depreciation.
5. Special depreciation provisions
Additional / Accelerated Depreciation
Schedule 2 provides an additional one-third of the applicable depreciation rate for certain qualifying projects/entities.
The exact qualifying category must be checked against the current Section 11 and Section 19 wording for the relevant income year.
Current FY 2083/84 reference material continues to recognise additional depreciation for specified qualifying infrastructure/special-industry categories.
Example
Normal Class D rate: 15%
Additional one-third of rate: 15% × 1/3 = 5%
Possible qualifying rate: 20%
This concession should not be applied merely because a business calls itself an industry.
Eligibility must first be established.
Renewable Energy Asset Provision
Schedule 2 provides special treatment permitting 50% of qualifying capitalised property used to generate renewable energy required for the person's own business to be claimed under the relevant provision.
This should be evaluated separately from the ordinary A–D pool calculation.
Fiscal Printer / Cash Machine
Schedule 2 also contains special immediate deduction treatment for qualifying fiscal printer/cash-machine expenditure where the statutory conditions are satisfied.
6. Tax reconciliation and records
Accounting-to-Tax Example
Financial statements show: Accounting depreciation: NPR 700,000
Tax depreciation under Schedule 2: NPR 950,000
Tax reconciliation: Accounting profit
Accounting depreciation: NPR 700,000
− Tax depreciation: NPR 950,000
Net tax adjustment: NPR 250,000 reduction from accounting profit, before other tax adjustments.
Tax Depreciation Register
CMA recommends maintaining a separate tax fixed-asset schedule containing:
asset description;
acquisition date;
tax class;
accounting class;
cost;
qualifying-use date;
opening tax pool;
addition timing factor;
disposal date;
disposal proceeds;
tax depreciation;
closing tax pool;
accounting carrying amount;
temporary difference;
supporting invoice;
payment evidence.
7. Year-end checks
Audit / Tax Review Checklist
Obtain fixed-asset register
Reconcile opening tax pools
Verify ownership
Verify business/investment use
Separate land from buildings
Classify A–E correctly
Check acquisition date
Apply 3/3, 2/3 or 1/3 addition rule
Reconcile disposals
Check disposal proceeds
Check accelerated-depreciation eligibility
Review renewable-energy assets
Review fiscal printer/cash-machine treatment
Add back accounting depreciation
Claim Schedule 2 depreciation
Reconcile closing tax pool to next year
Common Mistakes
Using Companies Act/accounting depreciation rates for tax
Claiming the full cost of every new asset in the tax pool immediately
Ignoring the acquisition-period rule
Failing to reduce pools for asset disposals
Including land in the building depreciation pool
Applying additional one-third depreciation without verifying eligibility
Using accounting carrying amount as the tax written-down value
Official Source Note
IRD currently publishes the Income Tax Act consolidated through Finance Act 2082 and the separate gazetted Finance Act 2083 for the current FY. IRD also currently lists the Income Tax Rules, 2059 including the Sixteenth Amendment.
Further guidance and practical checks
Tax depreciation can materially differ from accounting depreciation. Businesses should maintain a separate tax depreciation schedule and reconcile it annually with the financial-statement fixed-asset register.
