Retro pay, or retroactive pay, is a type of compensation due to an employee for the work he or she performed during a former (retro) pay period. Retro pay is given out by employers when they’ve paid what the worker was due and vice versa.
This is an appropriate compensation for past mistake. This could be the result from late raises, unpaid overtime or even miscalculated wages. Retro pay makes sure that employees are given their earned salaries.
Why Retroactive Pay Happens
There are many reasons why retroactive pay can be given.
Retro pay: If salary increase is approved but not processed timely, it is covered by the late Raise.
Retroactive adjustments: As it relates to Retroactive adjustments, they may sometimes be a result of Collective bargaining agreements or contract changes.
Human error in the payroll system will lead to incorrect payments and that will need to be fixed.
New Role or Title: Even if an employee receives a new post and receives a new pay, the new pay may not come to effect immediately.
Again, all these outcomes result in a post payment adjustment.
How Retro Pay Works
The retroactive pay is normally calculated by finding the difference between the rate here which was new and the old rate, and then multiplying the hours worked in the affected period.
Say you got a meager $1 raise two months ago, and you were paid at your old rate – then all the time since the raise date that you worked, you’d be paid the difference.
In most cases, this payment is made by your employer and is included in your next check, or paid out in a separate check.
Retro Pay vs Back Pay
While the terms are sometimes mistaken for one another, they are actually distinct:
Retro Pay: Adjusts wage differences due to changes like raises or promotions.
Wages behind payments: This is unpaid wages for work done due to legal difficulties or violations.
Retro pay is proactive and is being done inside the company while back pay are using legal claims or settlements to claim back their pay.
Is Retro Pay Taxable?
However, retroactive pay definitely counts as taxable income. It is considered as regular income and subject to same deductions. This includes:

Medicare
Other withholdings (like retirement contributions)
Be aware the lump sum payment will be a slightly higher tax.
