What to Do If You Get an IRS or NJ Division of Taxation Notice

First, actually read the whole notice

It's tempting to skim a government letter and assume the worst. Notices usually state clearly what they're about: a discrepancy between what you reported and what a third party reported, a math correction, a missing form, or a request for documentation supporting something on your return. The notice number, usually in the top corner, tells you what type of notice it is and often what response is expected.

Check the deadline

Most notices include a response deadline, often 30 days. Missing it can limit your options, for example, the ability to dispute a proposed change before it becomes final. Even if you're not sure how to respond yet, noting the deadline and starting the process well before it arrives gives you room to figure things out.

Don't assume it's correct, and don't assume it's wrong

Notices are often generated by automated matching, comparing what you reported to what employers, banks, or clients reported to the IRS or state. Sometimes the notice is right and reflects something genuinely missing from your return. Other times, the mismatch is due to a timing issue or an error on the third-party form. Either way, the right first step is figuring out which one it is, not assuming.

Respond with documentation, not guesswork

If the notice asks for support for a deduction, credit, or income figure, gather the actual documentation, receipts, statements, prior correspondence, rather than responding based on memory. A clear, documented response is generally resolved faster than a vague one.

When it's worth getting help

Simple notices, like a straightforward math correction you agree with, are often fine to handle on your own. Notices involving larger dollar amounts, proposed penalties, audits, or anything you don't fully understand are worth having a preparer review before you respond. Once you've responded to a notice, it's harder to walk back an answer that turns out to be incomplete or incorrect.

Common types of IRS and NJ notices

A few notice types account for most of what we see. A CP2000 notice from the IRS flags a mismatch between your return and income reported by an employer, bank, or client, and proposes a change rather than finalizing one automatically. A math error notice corrects a calculation on your return and adjusts your refund or balance due accordingly. A New Jersey Division of Taxation notice of balance due follows an assessment where the state believes tax, penalty, or interest is still owed. Each type has a different response path, which is part of why reading the notice number and heading carefully matters before deciding how to respond.

What happens if you don't respond

Ignoring a notice doesn't make it go away. If a response deadline passes without action, the IRS or New Jersey can generally finalize a proposed change, assess additional tax, penalties, and interest, and move toward more active collection, such as a levy or lien, in more serious cases. Responding late is still usually better than not responding at all, but the further past the deadline, the fewer options remain for disputing a proposed change before it becomes final.

Setting up a payment plan on a balance due

If a notice confirms you owe tax you can't pay in full, both the IRS and New Jersey Division of Taxation offer installment agreements. Setting one up generally requires providing basic financial information and generally stops more aggressive collection action while payments are current, though interest typically continues to accrue on the outstanding balance. We handle payment plan setup as part of resolving notices for clients rather than treating it as a separate service.
