Calculator

Estimate your quarterly payments

Individuals who expect to owe federal tax that is not covered by withholding generally make quarterly estimated payments. This tool applies the general safe-harbor rules.

  • Safe harbor: pay at least 90% of the current year’s tax or 100% of the prior year’s tax (110% if prior-year AGI exceeded $150,000).
  • If the balance after withholding is less than $1,000, estimated payments are generally not required.
  • Florida does not impose a personal income tax, so only federal estimates are considered here.
