Common confusion points

Form vs. Private Letter Ruling

Users think Form 8940 is a PLR request

→ Verify if you need a binding ruling (Form 1455) instead

Mailing address

Different IRS offices handle different issues

→ Double‑check the address in the current instructions

Signature authority

Some entities require an officer’s signature

→ Confirm who is authorized to sign for your entity

Tax year reference

Users often list the current year instead of the year of the issue

→ Match the year to the tax period in question

Attachments limit

No explicit limit, but oversized packets may be returned

→ Keep total size reasonable and label each attachment
