What is retroactive pay and how to calculate it


Key Takeaways

  • Retroactive pay is money paid to an employee to compensate for a payment deficit calculated in the previous pay period.

  • Back pay must be issued when an employee wasn't paid at all for money owed. Consider it money "from the past," whereas retroactive pay is simply a partial, current deficit.

  • After you calculate what the employee is owed, don't forget your legal liabilities. Retroactive pay is subject to standard payroll deductions.


  • As a business owner, you're obligated to compensate your employees accurately. Sure, you've got the routine payroll processing handled, but what do you do if things go awry?

    Sometimes clerical errors happen, or an employee's wages change mid-payroll cycle and you owe them for funds that didn't make it onto their last paycheque. In cases like that, understanding retroactive payment will help keep you in compliance. 

    What is Retroactive Pay?


    Retroactive pay is money paid to an employee to compensate for a payment deficit calculated in the previous pay period. Also known as "retro pay" or a "retro adjustment," these funds should be issued in the upcoming pay period, or with a supplemental payment, soon after the error is found. 

    When is retro pay necessary?

    Retroactive pay is necessary when an employee is owed funds that weren't included on their most recent paycheque. There are several qualifying events where retro pay will be needed.

    An employee earns a bonus: If you've awarded an employee a one-time monetary bonus during the week, you can pay the amount on their next pay cycle using the label "retro" next to the amount.

    An employee gets a pay raise: If you've completed an employee performance review, or simply want to boost their wages due to merit, you can implement that on the next pay cycle. To compensate them for the increase in funds between the day of the raise and the next paycheque, you can enter a retroactive payment into the payroll processing.

    An employee's paycheque was erroneous: If the last paycheque was miscalculated, the missing funds can be issued with a retroactive payment. This might happen when a pay raise was omitted, hours were unaccounted for, a bonus was forgotten, or an accounting error occurred.

    An employee's overtime was miscalculated: If you offer your staff an increase in pay for working overtime or on holidays, it's possible to make an error in calculating the new wages. A retroactive payment can resolve the discrepancy.

    An employee's commission was omitted: If you run a small business and employees have to self-report commissioned sales — but they forget to do so — you can easily compensate them for their earnings by adding a retroactive payment on the next paycheque.

    As you can see, there are many reasons a retroactive payment might need to be issued. Bottom line: if an employee is owed compensation that wasn't on their most recent paycheque, a retroactive payment bridges the gap. This helps keep the employee happy and your accounting balanced.

    Retroactive pay vs. back pay

    So, what happens if the financial error isn't found right away? What if a raise isn't reflected on a person's paycheque for an entire year, or the contractual promise of a quarterly bonus is never awarded, and the employee is owed these funds?

    As an employer, you are legally required to offer back pay. This differs slightly from retroactive pay in a few ways.

    Back pay must be issued when an employee wasn't paid at all for money owed. Consider it money "from the past," whereas retro pay reflects a partial, current deficit. Back pay is often triggered by legal actions and is paired with fines and restitution.

    How to calculate retroactive pay

    If the employee is owed a flat-rate amount, such as a monetary bonus, you can simply add the dollar amount to the next paycheque and label it "retro pay." No calculations are needed.

    If the employee is due funds related to a wage increase or other ongoing change in pay, first determine if the employee is hourly or salaried, then do the calculations.

    Here's an example for each type of worker experiencing a wage change:

    Hourly wage change

    Let's assume the employee was awarded a pay raise in the middle of the current payroll cycle. When they received their paycheque, they didn't see the additional funds reflected in their pay. If they were technically under the new rate for the last five days of the previous pay cycle, they are owed the difference between their new and past rate for the hours they worked in those five days.

    1. The employee worked 8 hours per day x 5 days = 40 hours at $17/hour. Since their new pay rate is $18/hour, they are owed an extra dollar for each of the 40 hours they put in at the new rate. Their retro pay is $40.

    Salaried wage change

    If an employee is promoted to a new position midweek, and it comes with a new salary, their next paycheque might not reflect the change. They should be issued a retro payment on the following paycheque for the partial week worked at their new salaried rate.

    The employee worked in the new position for 3 days in the pay period for which the new salary was not reflected. If their previous salary was $80,000 and their new position pays $100,000, they will make an additional $20,000 for their contracted year. If their year consists of 260 paid days, divide $20,000 by 260 to learn that their additional daily compensation is $76.92 in the new position. Take that amount times the 3 days they are owed, and their retro payment is $230.76.

    After calculating what the employee is owed, don't forget about your legal liabilities.

    Retroactive pay is subject to standard payroll deductions, including:

    • Federal, local, and provincial income taxes
    • Canada Pension Plan (CPP) contributions
    • Employment Insurance (EI) premiums
    1. Note: If the retroactive payment totals $3,000 or more in a lump sum, a special tax calculation must be implemented. Use Form T1198, Statement of Qualifying Retroactive Lump-Sum Payment.
