Standard Deduction

A simple guide to standard deduction, where it appears in salary tax calculation, and how it affects old vs new regime comparison.

Meaning

What is standard deduction?

Standard deduction is a fixed reduction from salary income. It lowers taxable salary without requiring investment proof like 80C or medical insurance proof like 80D.

For salaried employees, this deduction is usually visible in the salary calculation section of Form 16 Part B.

  • Applies to salary income
  • Reduces taxable income
  • Does not require investment proof
  • Should be checked in Form 16 Part B

Example

Basic example

If gross salary is ₹10,00,000, standard deduction reduces the salary income considered for tax calculation. The lower taxable income then flows into slab calculation.

Look in Part B

Form 16 Part B is the best place to confirm whether standard deduction has already been considered by payroll.

Regime

Standard deduction and tax regime choice

Standard deduction affects taxable income, so it can influence old vs new regime comparison. The final treatment depends on current rules and should be verified before filing.

When comparing regimes, use the same salary base and then apply the deductions available in each regime. That keeps the comparison clean.

  • Old regime comparison
  • New regime comparison
  • Taxable income impact
  • Form 16 cross-check

Example

Regime comparison

If standard deduction reduces taxable income in a regime, the slab tax is calculated on the reduced number. Even a fixed deduction can change the final tax result.

Do not isolate one item

Standard deduction is only one part of regime comparison. HRA, 80C, 80D, NPS, and other eligible deductions may matter more.

Checks

Common mistakes

The most common mistake is confusing standard deduction with 80C or entering it twice in a calculator. Another mistake is comparing regimes without checking whether the salary figure already includes this reduction.

  • Confusing standard deduction with 80C
  • Entering the same deduction twice
  • Ignoring taxable income impact
  • Not checking Form 16 Part B

Example

Double-counting example

If a calculator already applies standard deduction automatically, entering it again as another deduction can make taxable income too low.

Check calculator assumptions

Before entering standard deduction manually, check whether the calculator applies it automatically for the selected financial year and regime.

FAQ

Frequently asked questions
