Common confusion points

Extension vs. penalty relief

Users think Form 8809 also waives penalties

→ Verify if penalty relief is needed and use Form 1127 instead

Business vs. individual returns

Mistaking Form 8809 for personal extensions

→ Use Form 4868 for individuals

Mailing address variations

Different returns have different IRS addresses

→ Double‑check the instructions for the specific return type

Maximum extension length

Not all returns allow the same number of extra days

→ Review the specific return’s rules

Electronic filing availability

Some users assume all extensions can be e‑filed

→ Confirm e‑file support in the instructions
