TA stands for Travelling Allowance, DA stands for Dearness Allowance, and HRA stands for House Rent Allowance. The terms TA and DA refer to the funds paid by the company to their employees. The travelling or transport allowance covers transportation costs from a worker's home to their workplace. The Dearness Allowance measures inflation and salaries paid to government PSEs, employees, and pensioners. The dearness allowance in salary is expressed as a percentage of Basic pay+ Grade pay and is a living expense change to the allowance. A house rent allowance (HRA) is a salary component used to pay rent.
Maintaining a daily routine: To receive TA, one must adhere to the journey route when performing the duties.
Travelling from home to workplace: The rules for TA give an allowance for the route one follows from home to office or other work location. It is beneficial when one has to perform duties away from the office.
DA is location-dependent. This means that the money for dearness allowance will vary depending on where you live, as living costs vary by area. If a person lives in a smaller city or in the country, her DA will be lower than if you reside in a big city. A certain amount of money will be granted as DA during your working time, based on your pay.
