The penalty for underpaying estimated tax under IRC 6654 is different from almost every other penalty in this library. First-time abatement does not apply to it; the history test even excludes it. And the ordinary reasonable cause defense does not apply either.

IRM 20.1.3.2.7.1 says it directly: the penalty for underpayment of estimated tax cannot be removed or waived for reasonable cause alone. The IRS reasonable cause page says the same, listing the estimated tax penalty as one where reasonable cause does not apply.

What the statute offers instead is two specific waivers in IRC 6654(e)(3). They are narrow. They are also real, and the IRS has written guidance on exactly what qualifies.

Waiver one: casualty, disaster or unusual circumstances

IRC 6654(e)(3)(A) says no addition to tax shall be imposed for an underpayment to the extent the IRS determines that, by reason of casualty, disaster or other unusual circumstances, imposing it would be against equity and good conscience.

IRM 20.1.3.3.2.1.2 breaks that into two conditions, both required:

  • The failure to make estimated payments was due to casualty, disaster or other unusual circumstances, and not to any other reason.
  • Given all the facts, it would be against equity and good conscience to apply the penalty.

It adds a short reminder that does a lot of work: a recurring circumstance is not an unusual circumstance.

What the IRS says qualifies

The manual gives examples where the waiver may be granted if imposing the penalty would be against equity and good conscience:

  • Records destroyed by fire, flood or other natural disaster.
  • A taxpayer who becomes seriously ill or seriously injured and is unable to manage their affairs.
  • A taxpayer who designated a prior-year overpayment to be credited to estimated tax, where the overpayment was offset for past-due child support or non-tax federal debt and the taxpayer was not notified before the installment due date.
  • Certain situations where joint filers later file separate amended returns based on community property laws that incorrectly suggest one was under-withheld.

The manual notes the list is not all-inclusive. But it also lists what does not qualify.

What the IRS says does not qualify

IRM 20.1.3.3.2.1.2 says the waiver may not be granted if the failure was due to:

  • Reliance on the advice of a competent tax advisor. The manual makes a point of this: advisor reliance may be reasonable cause for other penalties, but it is not a basis for this waiver.
  • Retroactive application of a statute or regulation, unless the law itself, or IRS guidance published in the Internal Revenue Bulletin, grants a waiver.
  • Erroneous advice from the IRS, unless it falls within IRC 6404(f) and Treas. Reg. 301.6404-3. See erroneous IRS advice.
  • Lack of funds, or a pattern suggesting no attempt was made to estimate the tax at all.

And it says imposing the penalty is generally not against equity and good conscience if the circumstance was reasonably foreseeable, or if your actions afterward show you were not making a reasonable effort to comply.

The manual's examples make this concrete. Scheduled surgery might be a serious illness, but because it is scheduled, the taxpayer could have arranged the payments in advance. A taxpayer whose house burned down and who used funds for basic living expenses while waiting for insurance would normally qualify, but not one who spent the money on luxury replacements, and not one who failed to catch up on the missed payments after the insurance settlement arrived.

Waiver two: retirement or disability

IRC 6654(e)(3)(B) provides a second waiver. No addition is imposed if the taxpayer retired after reaching age 62, or became disabled, in the tax year for which estimated payments were required or the year before, and the underpayment was due to reasonable cause and not willful neglect.

This is the one place reasonable cause enters the estimated tax penalty. IRM 20.1.3.3.2.1.3 says reasonable cause is considered only when the individual meets the retirement or disability condition, and then only to determine eligibility for this statutory waiver.

The fact pattern is familiar. Someone retires and, for the first time in decades, no employer is withholding tax from their income. Pension, IRA distributions and Social Security may all be under-withheld. The waiver exists for that transition year, if the reason for the underpayment holds up.

A hypothetical retiree

Consider a hypothetical engineer who retired at 64 in March. For thirty years, her employer withheld enough to cover her tax. After retirement, her pension started without withholding, she took a large IRA distribution to pay off her mortgage, and nobody told her estimated payments were now her job. She filed on time the next April with a large balance due and an estimated tax penalty.

She meets the first condition of IRC 6654(e)(3)(B): she retired after reaching 62 in the year the payments were required. The second condition is reasonable cause, and her facts point that way: a lifetime of compliance through withholding, a first year without it, and prompt payment when the return was filed. Her request would attach proof of her retirement date and age, and a statement explaining the transition.

Change one fact, that she retired at 58, and the retirement half of the waiver is gone. The disability half might still apply if she retired because she became disabled. The statute draws the lines; the facts decide which side you are on.

How to ask

The Form 2210 instructions explain the process. Check box A in Part II to request a waiver of the entire penalty, completing only page 1, or box B to request a partial waiver, completing the form through line 18 and showing the amount you want waived in parentheses next to line 19. Attach Form 2210 to your return with a statement explaining why you could not meet the estimated tax requirements and the time period for which you request the waiver.

Documentation matters. The instructions say a retirement or disability request should include documentation showing your retirement date and your age on that date, or the date you became disabled. A casualty, disaster or unusual circumstance request should include documents such as police and insurance company reports.

IRM 20.1.3.3.2.1.2 adds that a waiver request under section 6654(e)(3)(A) must be in writing and signed by the taxpayer, cannot be granted on an oral request, and must be approved by a manager or designee. Do not try this one over the phone.

Federally declared disasters

For federally declared disasters, you usually do not need to ask. The Form 2210 instructions say the IRS automatically identifies taxpayers in a covered disaster area by county or parish and applies the relief, and that in general you should not file Form 2210 if the underpayment was due to a federally declared disaster. If you still owe a penalty after the automatic relief, the IRS will send a bill.

There are gaps. The instructions say taxpayers outside the covered area whose books, records or tax professionals' offices are in it, and relief workers assisting in the area, are also entitled to relief but must call the IRS disaster hotline to identify themselves. The broader disaster rules are covered in fire, casualty and disaster relief.

Before you ask for a waiver

Check whether you owe the penalty at all. Several statutory exceptions, and the annualized income installment method, can reduce or eliminate it without any waiver. Those are covered in estimated tax penalty exceptions and Form 2210.

Then, if a waiver is the right tool, ask for it in writing, with documents, on the form the IRS expects. The waiver is narrow, but when the facts fit, the statute says no penalty shall be imposed. For broader help with IRS penalties, see penalty abatement at getirshelp.com.
