What is a safe-harbor target?

It is the annual payment target used by the planner to help you evaluate estimated-tax penalty protection under the supported rules. It is different from the total tax you may ultimately owe when you file.

What does “catch-up amount” mean?

It shows how much of the cumulative target through the selected date is not yet covered by the withholding and estimated payments you entered. Paying it now can improve coverage, but it does not erase an underpayment that may already have existed for an earlier installment period.

Where do I find prior-year tax information?

Use your filed 2025 return. Look for the prior-year total tax and adjusted gross income requested by the planner. For state questions, use the corresponding figures from your 2025 resident state return. If you are unsure which number applies, use the review route rather than guessing.

What information should I have ready?

Your expected 2026 wages and withholding, business/1099 income and expenses, other supported income, estimated payments already made, and your 2025 federal and state tax information. You do not need to enter an SSN, bank account, or street address.

Important: This planner is an educational tax-planning tool, not a filed tax return or a guarantee of penalty avoidance. Results depend on the accuracy and completeness of the information entered. Specialty situations may be routed to review. The catch-up calculation measures target coverage and is not an exact installment-by-installment underpayment-penalty calculation.

We'll only ask what your selected state needs.

6. When are you checking?

The date matters because the planner separates amounts that may already be behind from the next future installment.
This controls which installments have already passed and which payment is next.
