You’re preparing accounts for a business, and everything looks fine. Profit is ₹5 lakh.
Then your CA says, “Taxable profit is ₹7 lakh.”
You pause.
“Wait… what? Same business, same year… how can profit be different?”
This is exactly where the concept of Book Depreciation vs Tax Depreciation enters — and honestly, this is where most students get confused.
Let’s sit and understand this properly, like we would in a real classroom.
Simple Concept Explanation (Clear + Direct)
At its core:
· Book Depreciation = Depreciation charged in financial statements (as per accounting standards)
· Tax Depreciation = Depreciation allowed by Income Tax for calculating taxable income
Same asset. Same business.
But two different rules.
Why Do Two Logics Exist?
This is not a mistake. It’s intentional.
Let me explain the thinking behind both:
1. Accounting Logic (Book Depreciation)
Accounting follows “true and fair view”.
👉 Objective: Show actual profit of the business.
So depreciation is calculated based on:
· Useful life of asset
· Actual wear and tear
· Matching concept
2. Tax Logic (Tax Depreciation)
Tax laws follow “revenue collection + policy support”.
👉 Objective:
· Standardization
· Control over tax calculations
· Sometimes encouraging investment (higher depreciation)
So depreciation is:
· Based on prescribed rates
· Fixed by law
· Often different from actual usage
🔥 Power Thought
Accounting asks: “What is the real profit?”
Tax asks: “How much tax should be charged?”
Why Students Struggle Here
In my teaching experience, students think:
👉 “Depreciation is depreciation… why two methods?”
That’s the mistake.
You’re assuming same purpose, but both systems serve different purposes.
Let’s Understand with Real-Life Examples
Example 1: Bhopal Retail Shop
A shopkeeper in Bhopal buys furniture worth ₹1,00,000.
In Books:
· Useful life = 10 years
· Depreciation = ₹10,000/year
As per Tax:
· Rate = 15% (WDV method)
· Depreciation = ₹15,000 in first year
👉 Result:
· Book profit is higher (less expense)
· Tax profit is lower (more deduction)
Example 2: Laptop Purchase by Freelancer
A freelancer buys a laptop for ₹80,000.
In Books:
· Life = 4 years → ₹20,000 per year
In Tax:
· Rate = 40% (IT Act)
· Depreciation = ₹32,000 in first year
👉 Big difference.
This is where students get confused:
“Sir, why government is allowing more deduction?”
Answer:
👉 To encourage digital investment and business growth.
Example 3: Manufacturing Unit in Indore
A factory buys machinery worth ₹10,00,000.
Books:
· Straight-line method → ₹1,00,000/year
Tax:
· 15% WDV → ₹1,50,000 in first year
Later years:
· Depreciation reduces in tax
· But remains constant in books
👉 Over time, total depreciation becomes same
But timing differs
Visual Analogy (Easy to Remember)
Think of depreciation like:
👉 Two people measuring distance:
· One uses actual steps (Accounting)
· Other uses Google Maps preset route (Tax)
Both reach destination
But the method and path differ

Student Confusion Moments (Very Real)
Confusion 1:
“Sir, if depreciation is higher in tax, why not use same in books?”
👉 Answer:
Because books are for investors, owners, banks
Tax is for government
You cannot mix both.
Confusion 2:
“Sir, does this mean company earns different profit?”
👉 No.
Company earns ONE profit.
But:
· Accounting shows real performance
· Tax adjusts it for legal calculation
Common Mistakes Students Make
❌ Mistake 1:
Assuming both depreciation must be same
👉 Reality: They are designed to be different
❌ Mistake 2:
Using tax rates in financial statements
👉 Wrong presentation of profit
❌ Mistake 3:
Ignoring timing difference
👉 This creates confusion in deferred tax later
Wrong vs Right Thinking
❌ Wrong Thinking:
“Depreciation is just a formula to apply”
✅ Right Thinking:
“Depreciation depends on PURPOSE — reporting vs taxation”
Why This Matters in Real Life
Let me be honest — this is not just an exam topic.
In real business:
· CA adjusts depreciation while filing returns
· Companies track both values separately
· It impacts:
o Profit
o Tax liability
o Cash flow
Practical Situation
A trader in Delhi shows:
· Book profit = ₹6,00,000
· Tax profit = ₹4,50,000
Why?
👉 Higher tax depreciation reduces taxable income
Result:
· Lower tax payment
· Better cash flow
Personal Teaching Story
I remember one student who kept asking:
“Sir, which depreciation is correct?”
He was trying to find one truth.
I told him:
👉 “Both are correct — but for different audiences.”
After that, everything clicked for him.
Sometimes confusion comes because we want one answer…
But commerce often gives context-based answers.

Reflective Question
Let me ask you:

Through Learn with Manika, I aim to make commerce learning clear, practical, and useful — whether you’re preparing for exams or trying to understand how things work in real life.
When I explain a concept, I always focus on the logic behind it, because once that becomes clear, confidence automatically follows.
