11. Depreciation Finalization — Companies Act vs IT Act
Depreciation is one of the most misunderstood yet most litigated year-end adjustments.While depreciation does not involve cash outflow, it has a direct and recurring impact on profit, tax liability, and credibility of financial statements.
This guide explains how to finalise depreciation correctly, why two different depreciation computations are required, and how to manage the differences without confusion or risk.
1. Introduction — Why Depreciation Finalisation Is Critical
Many SMEs assume depreciation is a “system-generated” figure that needs no review.In reality, depreciation errors are a frequent cause of audit adjustments and tax disallowances.
Depreciation impacts:
Profit & Loss account
Balance Sheet (WDV of assets)
Income-tax computation
MAT / AMT (where applicable)
Future years’ tax positions
A depreciation mistake made once continues to affect every future year until corrected.
2. Objective
To ensure that at year-end:
Depreciation is computed correctly under applicable law
Separate depreciation workings exist for books and tax
Differences are identified and reconciled
Supporting documentation is audit-ready
No excess or ineligible depreciation is claimed
3. Why Two Depreciations Exist
A fundamental principle to understand:
Depreciation as per Companies Act ≠ Depreciation as per Income-tax Act
They serve different purposes and follow different rules.
4. Depreciation as per Companies Act (Book Depreciation)
Purpose
To reflect true consumption of asset value
To present a true and fair view of financial statements
Key Features
Governed by Schedule II of Companies Act, 2013
Based on useful life of assets
Residual value considered
Method: SLM or WDV (as per policy)
Requires management judgment
Focus
Economic reality, not tax benefit.
5. Depreciation as per Income-tax Act (Tax Depreciation)
Purpose
To determine allowable deduction for tax computation
Key Features
Governed by Section 32 of Income-tax Act
Asset-wise depreciation replaced by block of assets
Fixed statutory rates
Half-year rule for additions
No residual value concept
Focus
Standardised tax computation, not asset life.
6. CABTA Framework — “The 7-Step Depreciation Finalisation Process”
Step 1 — Finalise Fixed Asset Base
Ensure:
Opening WDV matches prior year audited closing
All additions and deletions are finalised
CWIP is correctly segregated
Depreciation cannot be finalised unless asset base is correct.
Step 2 — Compute Depreciation as per Companies Act
For each asset:
Apply useful life
Apply method (SLM / WDV)
Consider residual value
Ensure consistency with accounting policy
This depreciation goes to P&L and Balance Sheet.
Step 3 — Compute Depreciation as per Income-tax Act
For each block:
Apply statutory rate
Apply half-year/full-year rule
Adjust for asset sales
This depreciation is used only for tax computation.
Step 4 — Identify Differences (Book vs Tax)
Common causes:
Different rates
Different methods
Timing differences
CWIP treatment
Prepare a depreciation difference statement.
Untracked depreciation differences create confusion during tax audit and assessment.
Step 5 — Pass Correct Accounting Entries
Only Companies Act depreciation is booked in accounts:
