Hands-on practice filling out real IRS forms from realistic taxpayer scenarios. AI generates a unique taxpayer profile every time — name, income, deductions — and you complete the forms line by line. Then AI checks every single line and explains any errors. Four difficulty levels: Easy (Form 1040 basic), Medium (+ Schedule A & B), Hard (+ Schedule C & SE), and Expert (full return with all schedules).
Practice completing the real IRS Form 1120-S using realistic S-corp scenarios. Fill in each income and deduction line, then submit for line-by-line checking. Computed lines (1c, 3, 6, 20, 21) are auto-calculated from your entries.
