Common confusion points

Foreign earned income exclusion

Taxpayers think all foreign wages are excluded

→ Verify the $120,000 (2024) limit

Deadline extensions

Some think the June 15 extension is automatic for all abroad

→ Confirm residency status qualifies

Signature requirement

Electronic filing may still need a PIN

→ Use the correct IRS e‑file PIN method

Form vs. Schedule

Users attach Schedule A mistakenly

→ 1040‑C only allows Schedule 1

Tax year labeling

The form header may show the prior year

→ Ensure top right box reflects the current year
