My YTD totals look wrong

• YTD too high for a new hire. Tick "I was hired in the past 52 weeks" and enter the pay periods worked. Otherwise we assume the employee was paid every period since January 1.
• YTD doubled this paycheck. Previous YTD must not include the current stub. Enter only what was paid before it; we add this paycheck.
• The count of paychecks is off by one. YTD counts periods up to the pay date, not the period end. Check the pay date on the Earnings step.
• The frequency is wrong. Bi-weekly (26 a year) and semi-monthly (24 a year) give different counts. Check "How often are you paid?".
• Taxes YTD don't equal rate × gross YTD. Social Security stops at the yearly wage base, and some state programs have caps, so their YTD can stop growing.

If you need full control, turn off Auto Calculator on the Payment step and type each YTD amount yourself. See typing amounts yourself.
