Penalty and Interest Abatement

Two main abatement pathways exist. First-time abatement (FTA) is administrative: if the prior three years show no penalties (other than an estimated-tax penalty), all required returns filed, and any current balance either paid or under an installment agreement, the IRS will remove failure-to-file, failure-to-pay, and failure-to-deposit penalties for the year in question on request. FTA does not require a narrative; it requires clean history and a phone call or written request.

Reasonable-cause abatement is the case-by-case path. The taxpayer submits a written narrative explaining the facts that prevented compliance, together with the supporting evidence. The IRS looks at four elements: what happened, when it happened, the effect on the taxpayer, and what the taxpayer did to comply once the impediment was gone. Recognized reasonable-cause categories include serious illness, death in the family, natural disasters, records destroyed, and reliance on a tax professional in some cases. 'I didn't know' is not reasonable cause; 'my accountant told me the extension covered payment too, here is the email' can be.

Interest abatement is much narrower. Interest is statutory and generally not abatable, but IRC §6404(e) allows abatement of interest that accrued due to unreasonable delay by the IRS itself (for example, a case that sat with an Appeals Officer for two years without action). Documenting the IRS-side delay is what makes an interest-abatement case succeed.

Order of operations matters. Ask for FTA first; if the year does not qualify, ask for reasonable cause on the same year. Do not pay the penalty before asking, unpaid penalties are easier to abate than refunds are to recover, and the request timing matters for interest that keeps accruing on the underlying balance.
