Why Your Paycheck Changed This Period

Purpose

Your net pay moved and you want to know why. Work it out from your own pay stub in three steps, then match what you find to a cause below.

1. Open the two stubs side by side from Payroll > Pay Stubs.
2. Compare the three totals: Employee Earnings, Employee Taxes Withheld, and Employee Deductions. One of them will account for the difference.
3. Inside that section, find the line that changed. Understanding Your Pay Stub explains each one.

Earnings changed

• Your hours varied. For hourly pay, more or fewer hours, including overtime, move gross pay directly. Check the Hours and Rate columns against your timesheet.
• A time entry was corrected. A punch you fixed, or one your manager corrected on your behalf, changes the hours that flow to payroll. Every such change is recorded on the entry itself with who made it and when, so open History on the entry to see what moved. See Troubleshooting: I Forgot to Clock In or Out.
• You had time off. Paid time off appears as its own earning line. Unpaid leave reduces your paid hours.
• A raise or job change took effect mid-period. A salary change effective partway through a pay period is prorated, so the first affected check mixes the old and new rates. The next check is your true new normal.
• A one-time item landed. Bonuses and commissions appear as their own earning lines. Approved expense reimbursements, including mileage, are paid out on the next payroll after approval and appear as a Reimbursements earning line. None of these change your base pay. See Submitting and Tracking Expenses.

Taxes changed

• You updated your W-4. Filing status, dependents, other income and extra withholding all move your tax, from the next payroll onward. Review your current elections under Payroll > Federal Tax Withholding.
• Your taxable wages crossed a threshold. Some taxes apply only up to an annual wage cap, and some start above a threshold, so withholding can shift late in the year even when nothing you set has changed.
• A pre-tax deduction changed. Pre-tax benefits reduce your taxable wages, so a benefits change also moves your tax.

Deductions changed

• Open enrollment elections took effect. A new plan year brings new per-pay-period costs.
• A life status change adjusted your election mid-year. For tax-advantaged accounts such as an HSA, the remaining annual amount is re-spread over the paychecks left in the year, so a mid-year increase lands harder per check than the same election made in January.
• A deduction with an annual goal finished or paused. Once the goal amount is met, that line stops.

It isn't the amount, it's the number of checks

• You were paid twice. Off-cycle and special payrolls, such as a correction or a separate bonus run, produce their own paycheck and their own stub rather than merging into your regular one. Both appear in Payroll > Pay Stubs.
• A balance was paid out. A time-off balance paid in cash appears as a PTO Balance Payout earning line, separate from your worked hours.

Still doesn't add up?

Compare the YTD columns on the stub. They show whether a line is genuinely new or has only changed size. If a line still looks wrong, contact your HR or payroll team with the Pay Date, the Voucher#, and the exact line item. They can trace it in payroll.

On the mobile app

You can open both stubs in the UZIO mobile app and make the same comparison. If a year or a pay date you need is not in the app's list, use the web portal. See Using the UZIO Mobile App.
