Common confusion points

Form 8453‑EX vs. Form 8453

Many think they are interchangeable; verify organization type first.

Signature requirement

Some software claims an electronic signature is enough; IRS still requires paper for exempt returns.

Mailing address

Different return types use different processing centers; double‑check the address.

Edition date

Using a prior year’s form can cause rejection; look for the year on the top.

EIN placement

Misplaced or mistyped EIN leads to processing errors.
