The Right to Pay No More Than the Correct Amount of Tax: Catching Errors and Misapplied Payments

Nobody likes paying tax. Paying the wrong amount of tax is worse. This right is about the second problem.

Section 7803(a)(3)(C) lists "the right to pay no more than the correct amount of tax." Publication 1 explains it as the right to pay only the amount of tax legally due, including interest and penalties, and to have the IRS apply all tax payments properly.

Two halves. The amount has to be right. The money has to land in the right place. In my experience, the second half causes as much trouble as the first.

Half one: is the amount right?

The amount the IRS says you owe can be wrong for many reasons. A few of the common ones:

• Processing errors. A number transcribed wrong from a paper return, a schedule that did not get picked up, a credit that was dropped.
• Information-return mismatches. The IRS compares your return to Forms W-2, 1099 and similar documents. If a payer reported the wrong amount, or reported it under the wrong person, your account can show income that is not yours.
• Adjustments you never saw explained. A math-error adjustment or an assessment from a notice you did not receive.
• Penalties and interest computed on a wrong base. If the tax is wrong, everything stacked on top of it is wrong too.

The test is always the same: compare what the IRS says to what your records show, line by line.

How to check the IRS's numbers

Start with the IRS's own records. You are entitled to see them.

1. Get the account transcript for each year in question. The IRS says the tax account transcript shows basic data such as filing status, taxable income and payment types, and also shows changes made after you filed your original return. Through your online account it is generally available for the current and nine prior tax years. See getting transcripts online or by mail.
2. Get the wage and income transcript if the dispute involves income. It shows data from information returns the IRS received, such as Forms W-2, 1098, 1099 and 5498.
3. Get the return transcript to confirm the IRS recorded your original return the way you filed it. It shows most line items from the original return as filed and is available for the current and three prior tax years.
4. Line them up against your copy of the return and your bank records. Mark every difference.

If you need help reading the transcripts, a professional can look at them with you under a Form 8821, which lets someone see your tax information without representing you.

Half two: did your payments land where they belong?

A misapplied payment is a payment the IRS received but credited to the wrong tax year, the wrong type of tax, or the wrong taxpayer. It is common, and it is usually fixable if you can prove what you paid and what you intended.

Signs of a misapplied payment:

• a balance-due notice for a year you know you paid,
• a refund or credit showing on a year you did not overpay,
• an estimated tax payment missing from the year it was meant for,
• a payment showing up on a spouse's or business account instead of yours.

Your IRS online account lets you view up to five years of payment history, including estimated tax payments, and pending and scheduled payments. That is the fastest place to look.

How to fix a misapplied payment

Assemble proof first, then ask.

Proof of the payment. A bank statement showing the debit, a cancelled check front and back, or the confirmation from the IRS payment system you used.

Proof of your intent. The memo line on the check, the tax year and form you selected online, or the voucher you mailed with it. When you pay by check, write your name, taxpayer identification number, the tax year and the form number on it. When you pay online, take a screenshot of the confirmation page.

The ask. Call the number on the notice, explain the payment, give the date and amount, and ask the IRS to move it to the correct period. Follow up in writing with copies of your proof. Send it in a way you can document; proof of mailing explains the options.

The timing rule that helps you. Under IRC 7502, a payment or document delivered by U.S. mail after the deadline is generally treated as made on the date of the postmark, if it was postmarked on or before the due date, properly addressed and mailed with postage prepaid. For registered mail, the registration date is treated as the postmark date. Certain IRS-designated private delivery services also qualify. Keep the receipt.

Prevention: pay so the money lands where you meant it

The cheapest misapplied payment to fix is the one that never happens. A few habits go a long way.

• Pay through your online account when you can. It shows you the tax year and type of payment before you submit, and the payment then appears in your payment history.
• Pick the year deliberately. Estimated payments for the current year and a balance due for a prior year are different payments. Select the right one every time.
• Write it on the check. If you pay by check, put your name, taxpayer identification number, tax year and form number on it, and include the payment voucher that came with your notice.
• Save the confirmation. A screenshot or PDF of the confirmation page, filed by tax year, ends most arguments before they start.
• Check that it posted. A few weeks later, look at your payment history or account transcript and confirm the payment shows on the year you chose.

Joint filers, former spouses and business owners should take extra care, because payments can post to the wrong taxpayer identification number when two accounts are involved.

When the IRS says you owe tax you do not owe

If the dispute is about the tax itself, not a payment, the path depends on where the case is.

• Before assessment, in an examination or a proposed adjustment notice: respond by the deadline on the notice with your documents. This is the right to challenge the IRS and be heard in action.
• After assessment: the tax has been recorded on your account. Depending on the facts, the remedies include asking the IRS to correct its own error, requesting reconsideration of an assessment, or filing a claim for refund if you paid. Refund claims have strict deadlines, and missing one can cost you the money for good. If you are near one, get help.

In every case, the best predictor of success is the quality of your paper. Tell the story in documents, not adjectives.

Interest and penalties: part of the correct amount

The right expressly covers interest and penalties. That cuts both ways. If the underlying tax is wrong, the interest and penalties computed on it should come down when the tax is corrected. And if the tax is right, the interest generally is too. Penalties are a separate question, often with their own relief rules, and are beyond the scope of this guide. Check that any correction you obtain flows through to the penalty and interest lines on your next transcript.

A short checklist

• Pull the account, return and wage and income transcripts for every year in question.
• Compare them to your return and your bank records.
• Check your payment history in your online account.
• Gather proof of every payment and of how you designated it.
• Ask the IRS to fix it by phone, then confirm in writing with proof of mailing.
• If the IRS does not fix it by the date it promised, the Taxpayer Advocate Service may take the case. See the TAS case acceptance criteria.

The IRS processes an enormous volume of paper and money. Mistakes happen on both sides. This right means that when the mistake is theirs, you are not the one who pays for it.
