Frequently Asked Questions
How many bi-weekly paychecks per year?
There are 26 bi-weekly pay periods per year. Two months each year will have 3 paychecks instead of 2, which can be helpful for budgeting or extra savings.
Bi-weekly vs semi-monthly?
Bi-weekly = every 2 weeks (26 periods). Semi-monthly = twice per month on fixed dates (24 periods). Bi-weekly means slightly smaller checks but 2 extra per year.
What is FICA tax and how much is withheld from my paycheck?
FICA stands for Federal Insurance Contributions Act and covers Social Security and Medicare taxes. For 2024, employees pay 6.2% for Social Security on wages up to $168,600 and 1.45% for Medicare on all wages, totaling 7.65%. High earners pay an additional 0.9% Medicare surtax on wages above $200,000 (single) or $250,000 (married). Your employer matches the 6.2% and 1.45%, meaning the total FICA contribution is 15.3% of wages.
How do pre-tax deductions affect my take-home pay?
Pre-tax deductions such as 401(k) contributions, health insurance premiums, HSA contributions, and FSA contributions are subtracted from your gross pay before federal income tax is calculated, which reduces your taxable income. For example, contributing $500 per bi-weekly period to a 401(k) reduces your federal taxable income by $500. At a 22% marginal tax rate, this saves $110 in federal taxes per paycheck. Note that Social Security and Medicare taxes are still calculated on your gross wages in most cases.
What is the difference between gross pay and taxable wages on a pay stub?
Gross pay is everything you earned in the period. Taxable wages are what remains after pre-tax deductions, and the figure differs by tax. Traditional 401(k) deferrals reduce federal and usually state taxable wages but not Social Security and Medicare wages, so FICA is still charged on them. Section 125 cafeteria-plan deductions such as health premiums, HSA and FSA contributions reduce both. That is why a stub commonly shows three different wage bases, and why they rarely match your salary divided by 26.
Why does my withholding not match the tax I actually owe at filing?
Withholding tables work by annualising each individual cheque as if the whole year looked like that period, then dividing the resulting tax across pay periods. Anything that breaks that assumption - overtime, a mid-year raise, a second job, self-employment income, large itemised deductions - creates a gap. Bonuses are frequently withheld at a flat supplemental rate rather than your marginal rate. The reconciliation happens on the return, and the W-4 is the instrument for closing the gap during the year.
How should I budget around the two months that contain three paychecks?
Twenty-six bi-weekly periods across twelve months means ten months with two cheques and two with three. The safest approach is to build the monthly budget on two paychecks so that fixed obligations are always covered, and treat each third cheque as a surplus assigned in advance - to an emergency fund, a debt paydown, or the annual expenses that never fit a monthly budget. Budgeting on an average of 2.17 cheques a month leaves you short in every ordinary month.
Which W-4 entries actually move my bi-weekly net pay?
Filing status sets which bracket schedule applies. The dependents step subtracts a credit amount directly from annual withholding, which is why claiming children visibly raises take-home pay. The other-income and deductions step lets you tell the employer about interest, dividends or side income to withhold more, or about large itemised deductions to withhold less. The extra-withholding line adds a flat dollar amount to every cheque and is the simplest tool for someone with two jobs or a habitual balance due.
What is the difference between my marginal and effective tax rate on a paycheck?
The marginal rate is what applies to your next dollar of income - the bracket you are sitting in. The effective rate is total tax divided by total income, and it is always lower because the brackets below yours are taxed at their own lower rates. A worker in the 22 percent bracket typically has a federal effective rate well below that. Use the marginal rate when deciding what a raise, an extra shift or a 401(k) deferral is worth, and the effective rate for budgeting.
Which deductions come out of pay after tax rather than before it?
Roth 401(k) contributions are post-tax by design, which is what makes qualified withdrawals tax-free later. Disability insurance premiums are often deliberately taken post-tax, because paying with taxed dollars makes any benefit received tax-free. Wage garnishments, union dues, most life insurance above the tax-free coverage limit, and charitable payroll deductions are typically post-tax as well. Post-tax items reduce net pay without reducing taxable wages, so they never lower your withholding.
