California semi-monthly paycheck calculator (2026)
24 paychecks per year on the semi-monthly schedule (15th + last day of each month). The California Labor Code section 204 legal minimum payment frequency for most non-exempt workers. Per-salary tables below.
Tax outcomes depend on your specific situation. This page summarises 2026 published guidance from the California FTB, IRS Pub 15-T, and California Labor Code section 204 (semi-monthly is the legal minimum payment frequency for non-exempt workers).
Semi-monthly mechanics in California
A semi-monthly pay schedule pays the worker twice per calendar month, almost always on the 15th and the last business day of the month (or the next business day if the 15th or last day falls on a weekend or holiday). Across a full calendar year, this produces 24 paychecks (12 months × 2 paychecks/month). Each paycheck represents 1/24 of annual gross. California Labor Code section 204 establishes semi-monthly as the legal minimum payment frequency for most non-exempt workers, payment for work performed in the first half of the month (1st-15th) must be made by the 26th of that same month, and payment for work performed in the second half (16th-end of month) must be made by the 10th of the following month.
Many California employers, particularly state and local government, large law firms, accounting firms, and professional services, default to semi-monthly because it aligns naturally with monthly bill cycles and accounting periods. Workers always know they will receive two paychecks per calendar month with no three-paycheck-month variation. The downside vs biweekly: each pay period covers a varying number of days (15 or 16 in the first half of most months, 13 or 15 in the second half depending on month length), which can complicate hourly time-card administration. For salaried workers this is irrelevant; for hourly workers, semi-monthly slightly complicates the relationship between hours worked and per-paycheck pay.

Semi-monthly vs biweekly: choosing between them
From a worker perspective, the choice between semi-monthly and biweekly is generally made by the employer rather than the worker. Both schedules produce the same annual take-home; the per-paycheck amounts differ slightly (semi-monthly produces $52,000 ÷ 24 = $2,167 per paycheck for a $52k salary, biweekly produces $52,000 ÷ 26 = $2,000 per paycheck). Both schedules satisfy California Labor Code 204. The structural differences:
Semi-monthly always produces exactly 2 paychecks per calendar month, aligning naturally with monthly bills (rent, mortgage, utilities, car payment, subscription services). Workers always know which dates the paychecks land on (15th and last day of month). No three-paycheck-month variation. Predictable, calendar-aligned, simple. Biweekly produces 26 paychecks per year, two of which fall in the same calendar month twice per year (the 'three-paycheck month'). This produces approximately $4,000-$5,000 of additional cash-flow flexibility annually that disciplined savers can capture for emergency funds, debt payoff, or retirement contributions. For workers who don't actively budget, biweekly's variation can feel inconvenient.
For hourly workers, semi-monthly slightly complicates the per-paycheck wage calculation because pay periods cover varying numbers of days (15 or 16 in the first half, 13 or 15 in the second half depending on month length). Biweekly's consistent 14-day period per pay cycle is easier to administer for hourly time-tracking. This is one reason many employers with large hourly workforces (retail, hospitality, construction) default to biweekly while many salaried-only employers (state government, professional services) use semi-monthly.
