The IRS Publication 509 tax calendar is the source to check for full due dates and weekend or legal holiday adjustments.
Payroll tax deposits may be monthly, semiweekly, or next-day under the $100,000 rule. Do not rely only on Form 941 dates.
Use 1099, paycheck, overtime, and employer cost calculators to estimate amounts, then verify official IRS filing and deposit deadlines.
