Corporate actions like bonus issues and stock splits often confuse investors because both increase share count and reduce share price. However, their underlying mechanics, accounting impact, and long-term implications are very different.
Whether you are passively holding assets or exploring the core principles of equity trading, understanding these differences is crucial—not just for knowledge, but also for portfolio tracking, tax calculation, and F&O adjustments.

What Is a Bonus Issue? (Quick Recap)
A bonus issue is when a company distributes additional shares to existing shareholders free of cost, using its accumulated reserves.
- No cash is paid by investors
- Company converts reserves into share capital
- Face value remains unchanged
👉 Example: In a 1:1 bonus, you receive 1 additional share for every 1 share held.
For a detailed explanation, read our guide on bonus issue meaning and impact.
What Is a Stock Split? (Quick Recap)
A stock split is when a company divides its existing shares into smaller units by reducing the face value.
- No reserves are used
- Face value changes (e.g., ₹10 → ₹1)
- Number of shares increases proportionally
👉 Example: In a 10:1 split, 1 share becomes 10 shares.
Bonus Issue vs Stock Split: 8 Key Differences
| Parameter | Bonus Issue | Stock Split |
|---|---|---|
| Face Value | No change | Reduced (₹10 → ₹1) |
| Reserves Usage | Uses reserves | No reserves used |
| Share Count | Increases | Increases |
| EPS Impact | Diluted | Adjusted proportionally |
| Accounting Impact | Reserves ↓, Share capital ↑ | No major accounting change |
| SEBI Rules | 12-month gap required | No strict restriction |
| F&O Impact | Lot size adjusted | Lot size adjusted |
| Tax Treatment | Nil cost for bonus shares | Cost apportioned |
Face Value Change (Most Important Difference)
This is the #1 concept most investors miss.
- Bonus Issue: Face value remains same
- Stock Split: Face value reduces
This impacts accounting, EPS, and long-term capital structure, which are vital components when analyzing a company's fundamental health.
Reserves Usage
Bonus issues reduce company reserves, which may limit future payouts like dividends or further bonuses. Stock splits do not affect reserves at all.
Impact on Share Count
Both actions increase share count and reduce price proportionally. However, ownership percentage remains unchanged.
Impact on EPS
- Bonus Issue: EPS decreases (same profit, more shares)
- Stock Split: EPS adjusts proportionally (no real dilution)
SEBI Rules
- Bonus issue: Cannot be issued within 12 months of previous bonus
- Stock split: No such restriction (minimum face value ₹1)
F&O Impact
Both actions trigger exchange adjustments:
- Lot size changes
- Strike prices adjusted
- Contract value remains same
Tax Treatment
- Bonus Shares: Cost of acquisition = NIL
- Split Shares: Original cost divided across new shares
This difference significantly impacts capital gains calculation.
What Stays the Same in Both?
Despite structural differences, both actions leave these unchanged:
- Total investment value
- Market capitalization
- Ownership percentage
👉 Simply put: No instant wealth creation.
Which Is Better: Bonus or Split?
From Company’s Perspective
- Bonus: Signals confidence, uses reserves
- Split: Improves liquidity and affordability
From Investor’s Perspective
- No direct financial gain in either
- Split improves liquidity more
- Bonus may create stronger sentiment
FAQs
Q1: What is the main difference between a bonus issue and a stock split?
Bonus issue uses reserves and keeps face value unchanged, while stock split reduces face value without using reserves.
Q2: Does a bonus issue change face value?
No, face value remains the same in a bonus issue.
Q3: Which is better for investors?
Neither creates immediate wealth. However, stock splits improve liquidity, while bonus issues signal financial strength.
Q4: How are they taxed in India?
Bonus shares have nil cost, while split shares have adjusted cost. Both follow standard equity taxation rules.
Q5: Can companies issue both?
Yes, but typically not at the same time. Strategic intent differs.
Q6: How does this impact F&O positions?
Both result in adjustment of lot size and strike price to maintain contract value.
Q7 Is it better for an investor to receive a bonus issue or a stock split?
Neither event creates immediate financial wealth, as the total investment value remains the same. However, a stock split can improve overall liquidity by making shares more affordable, while a bonus issue signals strong accumulated reserves and financial health.
Q8 Does a bonus issue reduce the face value of a stock?
No. In a bonus issue, the company converts its accumulated reserves into share capital without altering the underlying face value of the shares.
Q9 How are capital gains taxes calculated on bonus shares versus stock splits in India?
For bonus shares, the cost of acquisition is considered 'nil' (zero), meaning the entire sale amount is subject to capital gains tax. For a stock split, the original purchase cost is proportionally divided among the newly generated shares.
Q10 Do bonus issues and stock splits affect my F&O positions?
Yes. Both corporate actions trigger adjustments on the stock exchange. The strike prices are adjusted downward, and the market lot size is increased proportionally so that the overall contract value remains unchanged.
