Why Tax Notices Are on the Rise in 2026 — And What to Do If You Get One
Key POINTS:
More taxpayers, including in Illinois, are receiving notices in 2026 because of expanded third-party reporting, automated IRS matching systems, and stronger identity protection efforts — not because audit rates have spiked.
Receiving a notice is not the same as being audited; many are routine requests for clarification or documentation.
Knowing how the IRS actually communicates (mail first, rarely by phone, never by text or social media) helps taxpayers spot scams immediately.
A short, practical checklist — don't ignore it, don't panic, don't pay automatically, read it carefully, send it to your advisor, and keep a copy — covers what to do when a notice arrives.
Tax season ends, but for a growing number of taxpayers, the mail doesn't stop. If you've opened your mailbox this year and found an envelope from the IRS — or your state's department of revenue — you're far from alone. More taxpayers are receiving tax notices in 2026, and for many recipients, they do not indicate any wrongdoing.
That distinction matters. A notice can trigger a wave of anxiety before anyone has even opened the envelope. But understanding why these notices are becoming more common, and knowing exactly what to do when one arrives, could turn a stressful moment into a quick, manageable task.
Why Are More Taxpayers Receiving Notices in 2026?
Several converging factors are driving the increase — and almost none of them point to a sudden rise in taxpayer wrongdoing.
Expanded Third-Party Reporting
Tax authorities now receive more information directly from third parties than ever before. Employers, financial institutions, brokerage firms, and payment processors all report income and financial activities straight to the IRS. As these reporting requirements have expanded, tax agencies simply have more data points to compare against what taxpayers report on their returns.
Enhanced Automated Matching Systems
The IRS uses automated matching systems to compare information reported on tax returns with data provided by employers, financial institutions, and other third parties. When these systems detect a discrepancy, the return may be flagged for further review. If the issue cannot be resolved through internal IRS processes, the taxpayer may receive a notice, such as a CP2000, requesting clarification or additional information.
Although IRS audit rates remain historically low—generally under 1% for most individual taxpayers—the agency increasingly relies on automated matching programs, correspondence examinations, and targeted compliance initiatives to identify and review potential reporting inconsistencies. Returns claiming deductions or credits that require detailed eligibility determinations and supporting documentation may receive additional scrutiny if the documentation is incomplete or insufficient.
Importantly, many IRS notices are routine requests to verify information and do not necessarily indicate that the taxpayer has done anything wrong.
More Identity Protection Efforts
To combat tax-related identity theft and fraud, the IRS has expanded its identity verification and protection programs. As a result, some taxpayers may receive notices requesting additional verification before returns are processed or refunds are issued.
Similar Trends at the State Level
This isn't just a federal phenomenon. State tax authorities have also strengthened their data-matching capabilities, compliance reviews, and identity protection programs, which means taxpayers may receive notices from state agencies for many of the same reasons they receive them from the IRS.
As an example, we have observed an increasing number of notices from the Illinois Department of Revenue requesting supporting documentation to substantiate property tax credit claims for a taxpayer’s principal residence, as well as deductions claimed for contributions to 529 college savings plans.
A Notice Doesn't Mean You're Being Audited
This is worth repeating: receiving a notice does not mean that you or your return preparer made a mistake or did something wrong on your return.
Many notices are generated automatically and simply request clarification, documentation, or verification of information already reported on a return. Every notice deserves to be taken seriously, but "serious" and "alarming" are not the same thing. In many cases, the matter can be resolved with a factual response. However, the processing times vary and some tax authorities may take several weeks to months to review and respond.
How the IRS Actually Contacts Taxpayers
Knowing how the IRS communicates could help protect you from scams and impersonation attempts, which often increase when the agency sends out more notices.
In most cases, the IRS first contacts taxpayers by letter through the U.S. Postal Service. It may communicate electronically only when a taxpayer has specifically given permission, with limited exceptions. The IRS generally does not initiate contact by phone, though it may occasionally use automated messages directing taxpayers to IRS.gov — and those messages never include specific account details.
A phone call, email or text message isn’t from the IRS if it:
Is unexpected
Rushes you
Threatens you
Asks for personal or financial information
Demands payment now
A social media direct message is never from the IRS.
If contact arrives in any of these forms, it's a sign of a scam — not a legitimate notice.
What Should You Do If You Receive a Tax Notice?
A practical, level-headed checklist could help you handle a tax notice efficiently.
Read Our Approach to Tax Planning
Don't ignore it. Tax notices often include a response deadline. Letting one sit unopened or unanswered could allow a simple issue to become a more complicated one — potentially leading to additional penalties or interest.
Don't panic. Most notices can be resolved with additional information, clarification, or documentation. Receiving one does not automatically mean you've done something wrong.
Read the notice carefully. Review it in full to understand exactly what the tax authority is requesting and whether any action is required on your part.
Don't automatically pay it. Before sending payment, confirm the notice is accurate. Tax authorities can make mistakes, and there may be information that supports your original return.
Send the notice to your advisor immediately. If Capstone prepared your return, send us a copy of every page of the notice as soon as you receive it. Complete documentation helps us evaluate the issue and determine the right response quickly.
Keep a copy for your records. Always retain a copy of any notice or correspondence from a tax authority. You may need it later if additional questions arise.

FAQs
Q: Why am I getting a tax notice in 2026?
More taxpayers are receiving notices in 2026 because of expanded third-party reporting, enhanced automated matching systems that compare taxpayer returns with third-party data, and stronger identity verification efforts. This reflects expanded data and compliance processes, not a spike in audit rates, which remain below 1% for most individual taxpayers.
Q: Does receiving an IRS notice mean I'm being audited?
No. Receiving a notice does not mean that you made a mistake or did something wrong. Many notices are simply request clarification, documentation, or verification of information already on a tax return.
Q: How does the IRS contact taxpayers?
The IRS almost always uses the U.S. Postal Service for initial contact and rarely reaches out by phone. If you receive an unexpected call, email, text, or social media message demanding immediate payment or personal information, it is likely a scam. The agency will never use threats, rush you into a decision, or contact you through direct messages on social media platforms.
Q: What should I do if I get a tax notice?
Don't ignore it, since notices often include a response deadline. Don't panic, as most notices are resolved with additional information or documentation. Read the notice carefully before taking any action. Don't pay it automatically without confirming it's accurate. Send a complete copy to your tax advisor right away. Keep a copy for your records.
