⚠ If something goes wrong
Form 8879‑EG lets a taxpayer give an authorized electronic return originator (ERO) permission to file an estate, gift, or generation‑skipping transfer return electronically. It records the total tax amounts, the taxpayer’s PIN, and signatures from both the taxpayer and the ERO.
The taxpayer whose estate, gift, or generation‑skipping transfer return is being filed electronically must file Form 8879‑EG.
Part I lists the total tax amounts from the underlying return (e.g., total tax from Form 709 line 17, GST tax from Form 706‑GS(T) line 7). Part II captures the taxpayer’s declaration, PIN choice and signature. Part III records the ERO’s certification and electronic filing identification.
Do not send Form 8879‑EG to the IRS; the authorized ERO retains the completed form.
The ERO enters the taxpayer’s name and TIN at the top, then completes Part I with the total tax amounts from the return. The ERO gives the form to the taxpayer, who verifies the return, selects a five‑digit PIN (not all zeros), checks the appropriate box, signs and dates Part II, and returns the form to the ERO. The ERO then signs and dates Part III, enters the six‑digit EFIN and the taxpayer’s PIN, and retains the form for three years.
If the form is incomplete or unsigned, the electronic return cannot be transmitted, delaying the filing of the tax return.
Because the form states not to send it unless requested. Verify you are delivering it only to the ERO.
Misreading the instruction that says not to enter all zeros. Ensure the PIN is five digits and not all zeros.
