# Concept of Capital and Revenue Receipts
Income tax is charged on income. To know what is income, you must distinguish receipts along five contrasting axes. Master these pairs — they recur throughout the syllabus.
## 1. Regular Receipt vs. Casual Receipt
| Regular Receipt | Casual Receipt |
|---|---|
| Income expected to flow in regularly from a defined source — e.g., salary, rent | Irregular/one-time earnings — e.g., lottery, crossword-puzzle winnings |
Key point: Even casual receipts are taxable income under the Act. "Casual" does not mean "exempt."
## 2. Revenue Receipt vs. Capital Receipt
| Revenue Receipt | Capital Receipt |
|---|---|
| Earnings from regular business/activity | Receipts from sale of a fixed asset / capital base |
| Generally taxable | Generally not income… |
…BUT the Act specifically brings certain capital gains (profit on transfer of capital assets like land, jewellery) into the charge of tax. So "capital receipt is not income" is a general rule with statutory exceptions.
## 3. Net Receipt vs. Gross Receipt
- Net Receipt = total earnings minus allowable expenses incurred to earn that income. Income is taxed on a net basis.
- Gross Receipt = total inflow before expenses. The Act specifies which expenses are deductible. Some presumptive schemes compute income as a percentage of gross receipts.
## 4. Due Basis vs. Receipt Basis
- Due (Accrual) Basis: income is taxed when earned, even if not yet received.
- Receipt Basis: income taxed only when actually received — e.g., interest on compensation/enhanced compensation is taxed only on receipt.
- The taxpayer's method of accounting (cash vs. mercantile) governs which basis applies.
## 5. Application of Income vs. Diversion of Income (very important)
This pair decides who pays tax.
| Application of Income | Diversion of Income |
|---|---|
| Income first reaches the taxpayer, who then applies it to discharge an obligation | Income is diverted before it reaches the taxpayer, due to an overriding obligation/title |
| Voluntary or self-imposed obligation | Overriding charge at source |
| Taxpayer IS taxed | Taxpayer is NOT taxed (it never became his income) |
The test: Does the obligation attach to the source of income (diversion — overriding title) or only to the income after it has accrued/reached the assessee (application)?
