Types of Penalty Abatement
First-Time Penalty Abatement (FTA)
The IRS grants FTA automatically to taxpayers who have filed on time, paid their taxes on time, and have not been assessed any penalties in the prior three years. This is one of the most underutilized IRS relief options — many taxpayers who qualify simply don't know to ask for it.
Reasonable Cause Abatement
If you had a legitimate reason for failing to file or pay — such as a serious illness, natural disaster, death of a family member, or other circumstances beyond your control — the IRS may grant abatement on reasonable cause grounds. Documentation is critical for these requests.
Statutory Exception
Applies when a taxpayer relied on incorrect written advice from the IRS itself. Not common, but applies in specific situations.
Administrative Waiver
The IRS occasionally grants relief through formal programs and IRS notices when systemic issues affected a broad group of taxpayers.
How to Request Penalty Abatement
FTA can often be requested by calling the IRS directly once your compliance is in order. Reasonable cause abatement requires a written request that presents a clear, documented narrative of the circumstances that prevented timely filing or payment.
