Read the whole notice
Find the agency name, the notice number, the tax year, the date and the response deadline. Read what the agency says is wrong and what it asks you to do. Notices differ widely. Some require no action, some demand a payment and some require documents. Put the response date on your calendar at once.
Check that the notice is addressed to you and refers to your records. Scammers send fake notices, and the real agencies do not demand payment by gift card or cryptocurrency or by threatening phone calls. If something looks wrong, contact the agency through its published number.
Do not ignore it and do not panic
Ignoring a notice is the worst option because deadlines may carry penalties or lose appeal rights. A quick, accurate response often resolves the issue. If you cannot reply on time, call the number on the notice and ask what options exist.
Do not send original documents. Send copies, and keep proof of mailing or an upload confirmation.
Compare it to your own records
Pull the return for the year in question and the books behind it. Many notices come from mismatches between information reported by others, such as forms from payers, and what appears on your return. Find the form or income item named in the notice and check whether it is in your books.
Sometimes the agency is right and a form was missed. Sometimes the form is wrong. Sometimes the payer reported someone else's number as yours.
Decide who responds
For simple notices you may respond yourself. For notices about large amounts, audits, penalties or payroll taxes, bring in your CPA, enrolled agent or tax attorney. They can often respond on your behalf if you sign a power of attorney form.
Forward the notice to your preparer quickly, along with the return and records. Preparers who filed the return are usually well placed to understand it.
Respond in writing and keep a file
Answer exactly what is asked. Include a short cover letter, copies of the supporting records, and your contact details. Send by a trackable method. Make a folder for the notice with the original, your response, proof of delivery and any later letters.
If you agree and owe money, ask about payment arrangements if you cannot pay in full. If you disagree, follow the instructions on how to dispute. Fix any bookkeeping cause so it does not repeat.
A first-week timeline
On day one, read the notice, log the response date and take a photo of every page. On day two or three, send a copy to your preparer and pull the related return and records. By the end of the first week, decide who will respond, whether you need an extension of time, and what documents are missing.
Working to a simple schedule keeps stress lower and leaves room for a polite request for more time if you need it. Agencies often grant it when asked before the deadline.
Worked example with numbers
A notice says you owe $842 for a missing 1099 income item. Read the notice number, tax year, deadline and amount. Compare to your books: you find the $2,300 payment in your records, reported on a corrected form that was never sent. Gather the evidence, write a short response explaining the difference and send it by the method on the notice before the deadline, keeping a copy and proof of mailing.
Mistakes that cost money
Ignoring the notice. Paying without checking. Responding by phone with no written record. Missing the deadline.
Check your work
Start a folder for the notice, your response and every reply received.
Common questions
Does every notice mean an audit?
No. Many are automated corrections or information requests. Read the notice to see which type it is.
Can my bookkeeper respond for me?
A bookkeeper can gather records, but representation before a tax agency generally needs an authorized representative. Ask your CPA or enrolled agent.
Does MCC Solutions represent clients before tax agencies?
We help organize records and bookkeeping that support a response. Representation should come from a qualified tax professional.
