What to do when an IRS or payroll tax notice shows up

Most tax notices are fixable, and the worst thing you can do is put one in a drawer. Read it, confirm it's real, note the deadline, and send it the same day to whoever handles that tax: your CPA for income tax, your payroll provider for payroll tax.

Read it before you react

Look for four things on the first page:

Some notices only tell you something, like a new unemployment tax rate for next year. Others ask for money or information by a date. The notice number tells your CPA or payroll provider which kind it is.

Make sure it's real

The IRS starts contact by mail, not by email, text or social media, and it doesn't demand payment by gift card or wire. If anything feels off, don't call the number on the notice. Log in to your IRS online account, or call the IRS at the number on its website, and check whether the balance or letter shows up there.

Send it to the right person

Scan the whole notice, every page, and the envelope if it shows a postmark date.

Don't miss the date

Even when you think the notice is wrong, respond by the deadline. If you need more time, your CPA can usually ask for it. Letting the date pass can add penalties or take away your chance to dispute it.

In a made-up example, a practice gets a state notice saying a payroll return for the third quarter is missing. The owner forwards it to the payroll provider the same afternoon. The provider finds the return was filed under an old account number, sends proof, and the notice closes in two weeks with no penalty. The same notice ignored for three months would have turned into a bill.

Why notices happen

Common causes I see are a payment applied to the wrong quarter, a name or tax ID that doesn't match, a payroll account that changed when a provider switched, or an estimated payment that was missed or late. Most of these are easy to fix with records in hand. That's one more reason to keep payment confirmations and payroll reports where you can find them.

Common questions

Should I call the IRS myself?
You can, but I'd talk to your CPA first. They know what the notice means and what to say, and they can often handle it for you.

What if the notice says I owe money I already paid?
Send your CPA or payroll provider the payment confirmation. Misapplied payments are common and usually fixable.

Can my bookkeeper respond for me?
Usually your CPA or payroll provider responds. Your bookkeeper supplies records and records whatever gets paid or refunded.
