In such circumstances, the government provides dearness allowance to employees to provide financial relief. But what are the different types of DA, how is it calculated, and is it subject to income tax? Let's learn the important points.
What is Dearness Allowance?
Dearness Allowance is paid as a fixed percentage of an employee's basic salary.

Variable Dearness Allowance (VDA): This allowance is provided to eligible employees as a relief from inflation, as per certain rules. It is especially important for eligible employees as per the Basic Salary Notification.
How is DA calculated?
DA calculation for central government employees is based on the average of the Consumer Price Index for Industrial Workers (AICPI-IW) for the previous 12 months and the formula prescribed by the Seventh Pay Commission. The calculation rules for public sector employees may be different.
Who benefits from the DA increase?
Central government employees and eligible pensioners benefit from the DA, or Dearness Relief (DR), increase. This includes eligible employees in the railway and defense sectors. State governments also announce separate rates for their employees.
Is DA taxable?
