You were paid for part of a period
If you started midweek, your first weekly check covers only the days you worked. On a biweekly or semimonthly schedule, a mid-period start can mean a check for a few days, followed by a full one. Compare the period dates and hours on the stub to your start date.
Payroll runs behind
Many employers pay in arrears: the Friday check covers the week (or two) that ended earlier. Your first payday may come a week or more after your first week of work, and your last check will arrive after you leave. This is a timing gap, not lost pay.
Your W-4 wasn’t on file yet
Without a W-4, payroll must withhold as if you were single with no adjustments. For a married parent of two earning $60,000, that means $969.04 a week instead of $1,065.58 once the W-4 is processed. The extra comes back at tax time, but you can stop it by submitting a W-4 on day one. How to fill out the W-4.
Benefits start later (or all at once)
Health coverage often begins on the first of the month after you start, or after a waiting period. Your first checks may have no premium deducted, and then a later check may catch up on missed premiums. Retirement deferrals can also begin after an enrollment window.
A sign-on bonus was included
Bonuses are supplemental wages, usually withheld at a flat 22% federal rate plus FICA and any state rate. A $2,000 sign-on bonus on that $60,000 salary adds about $1,407.00 to the check, not $2,000. Estimate a bonus.
Withholding treats a partial check like a small salary
Because withholding annualizes each check, a small partial check is withheld as if your salary were small. A three-day check is withheld at a lower rate, which can make the first check look better than expected per day worked. Our example: a full $60,000 weekly check takes home $1,065.58, while a three-day check ($692.31 gross) keeps 92% instead of 92%.
Later in the year: checks that change on their own
If you earn more than $184,500, Social Security stops once you reach that wage base and your checks get 6.2% bigger. Above $200,000, Additional Medicare of 0.9% starts. Some state programs, like New Jersey TDI and FLI, also stop at their wage caps. The calculator’s “Full year” view shows exactly when.
Frequently asked questions
Why is my first paycheck so small?
Usually because it covers only part of a pay period, because you are paid a week or two behind, or because deductions started in full on a partial check. Check the hours and dates on your stub first.
Why is my first paycheck bigger than the next ones?
Benefit deductions such as health insurance or a 401(k) often start a pay period or two after you are hired. Once they kick in, take-home drops.
Is my first paycheck taxed more?
Not by a special rule. But if you hadn’t turned in a W-4 yet, payroll must withhold as single with no adjustments, and a check that includes a sign-on bonus may be withheld at a flat 22% federally.
