## Meaning of "Salary" for Various Purposes
The definition of salary changes depending on what you are computing. This is one of the most heavily tested traps in the Salaries chapter, so commit the four definitions below to memory.
### 1. For Rent Free Accommodation (RFA)
```
Salary = Basic + D.A. (for retirement benefits) + Any Commission + Bonus
+ Taxable portion of allowances
```
This is the widest definition.
### 2. For RPF contribution u/s 17(1), VRS u/s 10(10C), Gratuity (Act NOT applicable) u/s 10(10)(iii), Leave Encashment u/s 10(10AA) and HRA u/s 10(13A)
```
Salary = Basic + D.A. (for retirement benefits) + Commission (as a % of turnover)
```
Note: only turnover-based commission enters here — not a fixed/flat commission.
### 3. For Gratuity where the Payment of Gratuity Act IS applicable
```
Salary = Basic + D.A. (any — whether or not it forms part of retirement benefits)
```
### 4. For Retrenchment Compensation
```
Wages = All monetary payments (except Bonus) + Allowances + Value of RFA
+ LTC + Commission
```

## Deductions / Exemptions NOT allowed under the Default Tax Regime [Section 115BAC]
Under the default (new) regime, the following salary-related benefits are forfeited:
- Helper allowance, Uniform allowance, Research/Academic allowance
- Allowances for Judges; salaries and pensions paid by the UNO
- Rent-free official residence to Judges
- Leave Travel Concession [Section 10(5)]
- House Rent Allowance [Section 10(13A)]
- Special allowances for personal expenses [Section 10(14)(ii)] — except transport allowance for the differently-abled
- Entertainment allowance and professional tax [Section 16(ii) & (iii)]
- Exemption for free food / non-alcoholic beverages / vouchers up to ₹50 per meal [Rule 3]
> Key contrast: Entertainment allowance deduction [Sec 16(ii)] and professional tax deduction [Sec 16(iii)] are available only if the employee opts for the Optional (old) regime. Professional tax paid/reimbursed by the employer is first added to salary and then allowed as a deduction under Section 16.
