Does this calculator include local taxes?
No. City, county and school-district income or payroll taxes are not included. If your area charges one, your real take-home pay will be a little lower.
How is each paycheck calculated?
Your yearly figures are worked out first and then divided by the number of pay periods in a year (52, 26, 24 or 12). Real paychecks can differ slightly because employers withhold with their own tables.
