Schedule 2 vs. Schedule SE – SE tax belongs on Schedule SE, not Schedule 2

Verify the tax type before choosing a schedule

→ Use the correct schedule

AMT calculation – many taxpayers skip the Form 6251 worksheet

Ensure AMT is calculated before entering Schedule 2

→ Re‑run the worksheet

Excess premium credit repayment – often confused with the regular credit

Compare Form 8962 repayment line with Schedule 2 line 2

→ Match amounts exactly

Early‑withdrawal penalty – sometimes omitted from line 3

Check 1099‑R for early‑distribution codes

→ Add penalty if applicable

State‑specific filing address – taxpayers use the wrong address

Look up the address in the 1040 instructions for your state

→ Use correct address
