Frequently Asked Questions

What are FICA taxes?

FICA (Federal Insurance Contributions Act) taxes include Social Security (6.2% up to $184,500 in 2026) and Medicare (1.45% on all wages). Both employee and employer pay equal shares. High earners pay an additional 0.9% Medicare surtax.

What is the Social Security wage base limit?

For 2026, the Social Security wage base is $184,500. You only pay the 6.2% Social Security tax on earnings up to this limit. Medicare tax has no wage base limit — it applies to all earned income. The wage base increases annually.

Why do biweekly employees get 3-paycheck months?

Biweekly pay happens every 14 days, giving 26 paychecks a year. Since 12 months average 30.4 days each, a 14-day cycle drifts against the calendar. Twice a year, that drift lines up so 3 paydays fall inside a single calendar month instead of the usual 2 — most often about 6 months apart, roughly in spring and fall.

Which months have 3 paychecks in 2027 if I'm paid biweekly?

It depends entirely on your specific first 2027 payday, since the pattern repeats on a 26-payday cycle. For a first payday of January 8, 2027, the bonus months land in April and September. Enter your own first 2027 pay date above to get your exact bonus months.
