Ohio and the IRS: Reading Both Letters Carefully

Start with your address

If you moved recently, check that the IRS and the state both have your current mailing address, since letters go to the address on file. A missed envelope can mean a missed date.

Then pull out the letter you actually have and confirm who sent it.

To tell who wrote to you, look at the letterhead first. An IRS letter carries a notice number, starting with CP or LTR, in the upper right corner, and you can search that number on IRS.gov. If it does not appear there or something about it looks off, the IRS page points you to a phone number to confirm it.

Two separate agencies

Ohio's tax agency is the Ohio Department of Taxation (tax.ohio.gov). Its individual page covers filing and paying taxes for individuals.

The IRS and this department do not share instructions or deadlines. This page does not describe Ohio rules, rates or reporting duties.

A scenario

A couple files jointly and the IRS sends a notice about a form that was never matched to their return. They gather the form, compare it to the return, and answer the IRS by the date on the notice.

If Ohio sends something later, they read it as its own letter and go to tax.ohio.gov for the agency's guidance.

Before answering, the couple sort their papers into two folders, one federal and one for anything from the state. In the federal folder go the notice, the return, the mismatched form and a short note of what they decided. They make a photocopy of anything they send, never the original, and write the mailing date on the copy.

Do and do not

A short list for the weeks after a notice.

If you reply by mail, choose a method that gives you a receipt. Federal law generally treats a timely postmarked item as timely, but the sender carries the risk when a postmark is late or unclear. Certified mail or a designated delivery service, plus a kept receipt, is the safer route.

When two agencies write about the same year, handle the one with the earlier date first, and do not wait to see what the other one says. A representative, such as a licensed tax professional, may help you sort out which letter needs what, and you can ask one to review both.

• Do answer the IRS by the date on its notice.
• Do keep copies of what you send.
• Do not pay anyone who calls and demands unusual payment methods, such as gift cards.
• Do not assume a state letter is the same as the federal one.

Where the tool helps

IRS Audit Defense Pro is software that helps you organize your facts and draft a response letter for your federal matter. You review it and send it yourself.

Reading what arrives next

After you respond, expect replies on their own schedules. Open every envelope, even ones that look like bulk mail, and sort by sender. The federal notice family on this site, such as CP2000 and CP11, each has a guide that explains what the follow-up usually looks like.

If a letter from Ohio arrives and you cannot tell whether it connects to your federal matter, call or write the Ohio Department of Taxation using details from tax.ohio.gov. Take notes, and keep them with your copies.

Keep the log updated each time something arrives so that you always know which reply is still outstanding and which agency is waiting on it.

Do this for every item, including small ones, since a minor letter can still carry a date.
