## Allowances — Classification by Tax Treatment
Allowances are monetary payments by the employer for specific expenditure (personal or job-related). They are part of wages/salaries and most are taxable unless a specific exemption applies. The crucial exam skill is sorting each allowance into the right bucket — note that treatment often differs between the Default Tax Regime (DTR / new regime, 115BAC) and the Optional Tax Regime (OTR / old regime).
### Bucket 1 — Fully Taxable under BOTH regimes
- Dearness Allowance, Overtime Allowance, Fixed Medical Allowance
- City Compensatory Allowance, Interim Allowance, Servant Allowance
- Project Allowance, Tiffin/Lunch/Dinner Allowance, Warden Allowance
- Non-practising Allowance, Any other cash allowance
- Entertainment Allowance (but a deduction is available to Government employees under OTR)
- Transport allowance to an employee other than a blind/deaf-and-dumb/orthopaedically handicapped employee
### Bucket 2 — Differential treatment between regimes
- House Rent Allowance [10(13A)] — exemption available only under OTR; fully taxable under DTR
- Special Allowances [10(14)] — see separate topic
- Exceptions partly exempt under BOTH regimes: (a) Travelling allowance, (b) Daily allowance, (c) Conveyance allowance, (d) Transport allowance to blind/deaf-and-dumb/orthopaedically handicapped employee (exempt up to ₹3,200 p.m.)
