Estimated Tax Penalty Waiver

An estimated tax penalty waiver is a request that the IRS excuse an underpayment charge that does apply, on one of two statutory grounds: a recent retirement after age 62 or disability, or a casualty, disaster or other unusual circumstance. It is made by checking a box on Form 2210 and attaching a written explanation.

Quick Summary

  • A waiver is not an exception. An exception means the charge never applied; a waiver means it applied and the IRS is being asked to excuse it.
  • Internal Revenue Code section 6654(e)(3) supplies two grounds and no others: a casualty, disaster or other unusual circumstance, or retirement after reaching age 62 or becoming disabled in the tax year or the one before it.
  • Asking for the whole penalty is less work than asking for part of it. Checking box A means you never compute the penalty; checking box B means you compute it in full and then subtract the amount you want waived.
  • A written statement is mandatory. It has to explain why you could not meet the estimated tax requirements and identify the period the request covers.
  • Normally the IRS computes this penalty and bills for it, so no form is filed. Requesting a waiver is one of the situations that makes filing Form 2210 compulsory.

Definition

An estimated tax penalty waiver is a request to the IRS to excuse all or part of the addition to tax that section 6654 imposes for underpaying estimated tax. The authority is section 6654(e)(3), headed "Waiver in certain cases," and the request is made on Form 2210, "Underpayment of Estimated Tax by Individuals, Estates, and Trusts," whose instructions carry a section headed "Waiver of Penalty."

The distinction that governs everything on this page is between an exception and a waiver. The exceptions in section 6654(e)(1) and (e)(2), and the safe harbors that keep most people out of the charge altogether, are covered under estimated taxes; where one of them applies, no addition to tax arises in the first place and there is nothing to excuse. A waiver operates on the other side of that line. The charge has arisen, the taxpayer is asking for it to be set aside, and the IRS decides.

Advanced Explanation

There are exactly two grounds, and the statute states them narrowly. Section 6654(e)(3)(A) allows the IRS to waive the addition "to the extent the Secretary determines that by reason of casualty, disaster, or other unusual circumstances the imposition of such addition to tax would be against equity and good conscience." Section 6654(e)(3)(B) covers a taxpayer who "retired after having attained age 62, or became disabled, in the taxable year for which estimated payments were required to be made or in the taxable year preceding such taxable year," where the underpayment "was due to reasonable cause and not to willful neglect."

Two details in that second limb are easy to lose. It is a two-year window keyed to the event, not a status: the retirement or the onset of disability has to fall in the tax year itself or the year immediately before it, so being retired for a decade is not a ground. And reasonable cause is a separate requirement stacked on top of the event, which means the retirement has to explain the shortfall rather than merely coincide with it.

The asymmetry between the two boxes is the most useful mechanical fact here, and it runs against intuition. Form 2210's Part II offers box A, "You request a waiver (see instructions) of your entire penalty," and box B, "You request a waiver (see instructions) of part of your penalty." Asking for all of it is the lighter task. The instructions say that a taxpayer checking box A completes only page 1 of the form and attaches it to the return, and "you aren't required to figure the amount of penalty to be waived." A taxpayer checking box B must complete the form through line 18 without regard to the waiver, enter the amount they want waived in parentheses on the dotted line next to line 19, subtract it from the penalty figured without the waiver, and enter the result. Partial relief therefore costs a full computation that total relief does not.

The written statement is not optional and its contents are specified. The instructions require the taxpayer to "attach Form 2210 and a statement to your return explaining the reasons you were unable to meet the estimated tax requirements and the time period for which you are requesting a waiver." Naming the period matters, because the charge is computed installment by installment, so a circumstance that existed in September has nothing to say about an April installment. A request grounded in retirement or disability must be supported by documentation showing the retirement date and the taxpayer's age on it, or the date disability began. A request grounded in a casualty or other unusual circumstance calls for documentation such as copies of police and insurance company reports.

Filing the form is what makes the request, and that reverses the normal posture. The default under the Form 2210 instructions is that "the IRS will generally figure your penalty for you and you should not file Form 2210." Requesting a waiver is one of the situations the instructions name in which a taxpayer must file it. Nothing on the return itself signals a waiver request, so a taxpayer who simply pays the bill when it arrives has not asked for anything.

Federally declared disasters mostly run on a separate track. The IRS identifies taxpayers in a covered disaster area by county or parish while processing the return and applies penalty relief automatically, and the instructions say that in general a taxpayer whose underpayment was due to a federally declared disaster should not file Form 2210 at all. The exception is worth knowing because it reaches people who assume they are outside the relief: an individual or fiduciary not in the covered area but whose "books, records, or tax professionals' offices are in a covered area" is also entitled, as are relief workers affiliated with a recognized government or charitable organization assisting in the relief activities. Someone in either of those positions is directed to call the IRS disaster hotline and identify themselves as eligible, rather than to rely on the automatic identification.

How to Remember

An exception says the charge never applied. A waiver says it applied and asks to be let off. And the counter-intuitive part of the form: asking for everything is easier than asking for some of it.

Used in a Sentence

“Having retired at 64 in the middle of the year and missed two installments on his pension income, Desmond attached a statement to his return requesting an estimated tax penalty waiver for the periods after he stopped working.”

How It Works

The sequence for making the request.

  1. Establish that a charge actually arose. If a safe harbor or one of the section 6654(e)(1) or (e)(2) exceptions applies, there is no penalty and nothing to waive.

  2. Match the facts to a ground. Retirement after age 62 or the onset of disability, in the tax year or the year before, plus reasonable cause; or a casualty, disaster or other unusual circumstance where imposing the charge would be inequitable.

  3. Choose the box. Box A for the entire penalty, which means completing only page 1 of Form 2210. Box B for part of it, which means computing the penalty in full first.

  4. Write the statement. Explain what prevented compliance and name the period covered. Attach documentation appropriate to the ground.

  5. File Form 2210 with the return. Without it, no request has been made.

  6. Wait for the decision. The instructions state that the IRS "will review the information you provide and decide whether to grant your request for a waiver."

A hypothetical example of the box A and box B choice. Suppose the IRS would compute a $680 penalty for the year, made up of $430 relating to the first two installments and $250 relating to the last two. A taxpayer who became disabled in July and asks for the whole $680 to be excused checks box A, files page 1 of the form, attaches a statement and the documentation, and never calculates anything. A taxpayer who accepts the $430 from the period before the disability and asks only for the $250 attributable to the months afterwards checks box B, works the form through to the penalty computation, shows the $250 in parentheses beside the penalty line, and reports $680 minus $250, or $430, as the amount. The second request is narrower, more clearly justified, and considerably more work.

Pros and Cons

What the waiver is good for

  • It reaches the two situations where the pay-as-you-go system is most obviously unfair: a year in which someone's income structure changed because they stopped working or became disabled, and a year disrupted by a casualty or disaster.
  • Requesting the whole penalty requires no computation, so the lightest form of the request is available to someone who cannot face the arithmetic.
  • The retirement and disability ground looks backwards as well as forwards, covering an event in the year before the one that produced the underpayment.
  • Relief for federally declared disasters is applied automatically by county or parish, so most affected taxpayers need do nothing at all.

Limits and costs

  • The grounds are closed. Ordinary hardship, an unexpected bill, a client who paid late or simply not knowing the rules are not among them.
  • The IRS decides, and the statute gives it discretion rather than obliging it, so a well-documented request can still be refused.
  • Reasonable cause is a second hurdle on the retirement and disability limb. The event alone does not carry the request.
  • Asking for part of the penalty is materially more work than asking for all of it, which can push a taxpayer toward an all-or-nothing request that fits their facts less well.
  • The request only exists if Form 2210 is filed, so a taxpayer who waits for the bill and pays it has forfeited nothing formally but has done nothing to ask.

People Also Asked

Answers to the most frequently asked questions.

What is the difference between a waiver and an exception to the estimated tax penalty?
An exception means the addition to tax never applied. The under-$1,000 rule, the no-liability-in-a-full-prior-year rule and the safe harbors all work that way, and they are covered under estimated taxes. A waiver under section 6654(e)(3) operates after the charge has arisen: the taxpayer concedes it applies and asks the IRS to excuse it on one of two statutory grounds. The practical difference is who acts: an exception operates by itself once its facts are met, while a waiver has to be requested on Form 2210 and the IRS decides whether to grant it.
Can I get the estimated tax penalty waived because I did not know I had to pay it?
Not on that basis. Section 6654(e)(3) supplies two grounds only: a casualty, disaster or other unusual circumstance where imposing the charge would be against equity and good conscience, and retiring after reaching age 62 or becoming disabled in the tax year or the one before it, where the underpayment was due to reasonable cause and not willful neglect. Unfamiliarity with the rules is not among them.
Why is it easier to ask for the whole penalty than for part of it?
Because of how Form 2210 is built. Checking box A, for the entire penalty, means completing only page 1 and attaching it to the return, and the instructions say you are not required to figure the amount to be waived. Checking box B, for part of it, means completing the form through the penalty computation, entering the amount you want waived in parentheses beside the penalty line, and subtracting it. The partial request is narrower but costs a full calculation.
What has to be attached to a waiver request?
Form 2210 itself, plus a written statement explaining why you were unable to meet the estimated tax requirements and identifying the time period the request covers. A request based on retirement or disability also needs documentation showing the retirement date and your age on it, or the date you became disabled. A request based on a casualty or other unusual circumstance calls for supporting documentation such as police or insurance company reports.
I was affected by a federally declared disaster. Do I have to request a waiver?
Usually not. The IRS identifies taxpayers located in a covered disaster area by county or parish while processing the return and applies the relief automatically, and the Form 2210 instructions say that in general you should not file the form in that situation. The exception is a taxpayer outside the covered area whose books, records or tax professional's offices are inside it, and relief workers affiliated with a recognized government or charitable organization: they are directed to call the IRS disaster hotline and identify themselves as eligible.
