Estimate only, not tax advice. Federal tax and penalties at the IRS's standard rates, before credits and state taxes. Unfiled-year tax uses 2025 brackets and assumes W-2 income had taxes withheld. Interest uses the IRS rate of 7% a year (October to December 2026), compounded daily; the rate resets every quarter.
