W-2 + one Schedule C activity
See what you may owe before tax time
The planner turns wage, business, withholding, and estimated-payment totals into a bounded 2026 federal estimate. It is designed for an early planning conversation—not tax-return preparation or filing.
How it works
1
Enter the essentials
Add filing status, combined W-2 boxes, federal payments, Schedule C income, and expenses.
2
Calculate once complete
The estimate stays locked until every required amount has a valid answer, including $0 where something does not apply.
3
Review the result
See the estimated balance or refund first, then review tax totals and how the estimate was calculated.
