Receiving a letter from the IRS or Arizona Department of Revenue (ADOR) can be stressful—but it doesn’t have to be a crisis. Whether it’s a simple math correction or a more serious compliance issue, the key is prompt, informed action.
At Concierge Consulting & Accounting, PLLC, we work with Paradise Valley clients to respond swiftly and strategically to IRS and state notices, helping them avoid penalties, reduce tax liabilities, and maintain peace of mind.
Why You Might Get a Tax Notice
Tax notices are more common than most people think. You might receive a letter due to:
- Math errors or mismatches between filings
- Unreported income (e.g., from 1099s, K-1s, or W-2s)
- Late filings or missing returns
- Unpaid balances or penalties
- Sales tax or payroll tax discrepancies
- Audits or information requests
The IRS and ADOR use automated systems to cross-check information, so even honest mistakes or timing issues can trigger a notice.
Common IRS and Arizona Tax Notices We Help With
- CP2000: Income mismatch between your return and third-party reports
- CP14: First notice of unpaid taxes
- CP501/CP503: Collection notices
- Letter 5071C: Identity verification
- Arizona Transaction Privilege Tax (TPT) errors or late filings
- Non-filer notices for businesses that missed deadlines
If you receive any letter from the IRS or state, do not ignore it—even if you think it’s wrong. Most notices come with a deadline to respond, and silence can escalate the issue.

FAQs: IRS and State Tax Notices
Can I ignore a notice if I already paid?
No—always confirm that the IRS or state has correctly credited your payment. Payments can be misapplied, especially if reference numbers were incorrect.
What if I disagree with the notice?
You can dispute it, but you must do so by the deadline. We’ll draft a formal response and provide backup documentation to support your position.
Will the IRS call me?
Generally no—most initial communication comes by mail. Be cautious of phone calls claiming to be from the IRS, as they are often scams.
Stay Calm. We’ve Got This.
If you’re in Paradise Valley and received a tax notice, don’t panic. Most issues can be resolved smoothly when handled promptly by a CPA.
