Taxable salary is not the same as CTC or monthly take-home pay. Salary can include cash pay, allowances, bonuses, commissions, perquisites and specified employer contributions. Each component must be tested against the provision and tax regime that applies for the relevant financial year.
Start with the actual salary documents
Use the offer letter, payslips, Form 16 and employer declarations to identify:
- cash salary and allowances;
- variable or contingent pay;
- employer and employee contributions;
- reimbursements supported by employment purpose and records;
- taxable perquisites; and
- tax deducted at source.
Payroll TDS is a credit toward the final computation. It is not proof that every item was classified correctly or that no further tax is payable.
HRA
Where Section 10(13A) is available, the exempt HRA amount is generally the least of:
- actual HRA received;
- rent paid minus 10% of the relevant salary; and
- 50% of the relevant salary for Mumbai, Delhi, Kolkata or Chennai, or 40% elsewhere.
The exemption is conditional and is not available merely because rent was paid. Salary definition, actual payment, documentation, residence and regime matter. Use the HRA Calculator for the mechanics, then include the result only where eligible.
Standard deduction and regime
NiyamFin's current tax calculators model FY 2025-26 / AY 2026-27 and display the standard deduction used by each regime. A later article or payroll period should not silently reuse those values.
The lower-tax regime depends on complete income and deductions or exemptions that are actually eligible. HRA, Section 80C, Section 80D, home-loan interest or employer NPS should not be treated as automatic amounts or as reasons to choose a regime without a complete comparison.
Perquisites and employer contributions
Company accommodation, vehicles, employee stock options and other benefits can use rule-based valuation. Employer contributions to recognised funds can also have statutory limits and conditions. A benefit label such as “reimbursement”, “NPS” or “allowance” does not make it exempt by itself.
Retirement and termination receipts
Gratuity, commuted pension and leave encashment use separate provisions, taxpayer categories, limits and conditions. Avoid treating them as universally tax-free. Verify the provision effective for the receipt date and the employee's status before computing an exemption.
Arithmetic example
Suppose the three HRA inputs are:
- actual annual HRA received: ₹3,00,000;
- annual rent minus 10% of relevant salary: ₹2,28,000; and
- applicable salary percentage: ₹3,60,000.
The mechanical HRA result is ₹2,28,000, the lowest of the three. This is an exemption amount only if the statutory and regime conditions are satisfied. It is not a promised personal tax saving; final tax depends on the complete computation.
Common errors
- treating CTC divided by 12 as monthly take-home;
- assuming an allowance or reimbursement is automatically exempt;
- treating a deduction ceiling as an amount automatically available;
- calculating a personal “saving” from an assumed 30% slab; and
- using payroll TDS as the final liability.

Review the actual component, effective period and eligibility conditions rather than changing salary structure solely for an assumed tax outcome.
