Yes, back pay is treated as taxable income for the year in which it is received, though it may be eligible for special tax relief in some jurisdictions if it relates to a prior year.

What's the difference between back pay and retroactive pay?

They are often used interchangeably. Strictly, 'back pay' often implies wages owed due to an error or dispute, while 'retroactive pay' implies wages from a new collective agreement applied to a past period.

How long can I claim back pay?

This is governed by employment law and statutes of limitations, which vary by country and sometimes by the type of claim (e.g., minimum wage, overtime). It can range from 2 to 6 years or more.

Does back pay include interest?

Often, yes. Courts and employment tribunals frequently award interest on back pay to compensate for the time value of the money that was wrongly withheld.
