“My CPA quoted $750 per year and stopped returning my calls. Found simple5472 at midnight, had the forms, cover letter, and a Reasonable Cause Statement I authored ready in 20 minutes for $179. Whether the IRS waives the penalty is up to them — but the filing is in.”

What a Reasonable Cause Statement is — and what it isn’t.
IRC §6038A(d)(3) directs the IRS to consider whether a late filing was due to reasonable cause and not willful neglect. The taxpayer is responsible for establishing that in writing. Most late filers don’t attach a statement — many aren’t aware they can. Whether the IRS grants any relief is determined solely by the IRS on a case-by-case basis.
Form alone
Filing Form 5472 by itself.
Under IRC §6038A(d)(1), the IRS may assess a $25,000 penalty for failure to file. With no written reasonable cause showing in the filing, the taxpayer has not put forward the position permitted by IRC §6038A(d)(3) at the time the return is submitted. Additional $25,000 penalties may accrue every 30 days after IRS notice if non-compliance continues.
What’s on the record
No written reasonable cause attached
Form + RCS
Filing with a Reasonable Cause Statement.
IRC §6038A(d)(3) directs the IRS to consider whether a late filing was due to reasonable cause and not willful neglect. The taxpayer is responsible for establishing this in writing, attached to the delinquent return. The IRS evaluates each request on its specific facts; the outcome is solely the IRS’s determination.

“I had missed two filing years and only found out about Form 5472 from a friend at a conference. My accountant quoted me $750 per year to catch up — then stopped returning my calls. I found simple5472 at midnight, went through the wizard in about 20 minutes, and had a complete package ready: forms, cover letter, Reasonable Cause Statement. I mailed everything via certified mail the next morning. I can't promise what the IRS will do, but the filing is in.”
