What Physicians Should Do After Receiving an IRS Notice or Audit

Understanding IRS Notices and Audits

Receiving an envelope from the Internal Revenue Service can trigger immediate anxiety, especially for physicians juggling patient care, practice management, and complex multi-state income streams. The good news is that most IRS notices are routine inquiries about mismatches in reported income or deductions, not full-blown audits. The critical factor is how quickly and accurately you respond.

The IRS sends millions of notices each year for issues ranging from simple math errors to requests for documentation of specific deductions. A small percentage escalate to formal examinations, but even routine correspondence notices carry strict deadlines and can result in substantial tax bills if ignored. Understanding the type of notice you received, the deadline to respond, and which professionals are authorized to represent you before the IRS can mean the difference between a quick resolution and years of collection activity.

Because physicians often earn income above the thresholds where the IRS increases scrutiny—such as the 37% bracket starting at $640,600 for single filers and $768,700 for married couples filing jointly in 2026—and frequently claim deductions for home offices, continuing medical education, professional expenses, and business use of vehicles, the risk of a mismatch or documentation request is higher than for W-2 employees in lower brackets.

Common Types of IRS Notices Physicians Receive

Not all IRS letters are the same. Here are the most common notice types that physicians encounter:

CP2000 Notice: Underreported Income

A CP2000 is not technically an audit; it is a matching notice. The IRS computers compare the income reported on your Form 1040 with information returns filed by third parties—Forms W-2, 1099-NEC, 1099-MISC, 1099-K, and 1099-INT. If the IRS records show more income than you reported, you receive a CP2000 proposing additional tax, penalties, and interest.

Physicians who work locum tenens assignments, receive honoraria for speaking engagements, earn royalties from publications, or operate side businesses may receive multiple 1099 forms that do not always match the amounts on their tax return, especially if income was deferred, reclassified, or offset by business expenses. A CP2000 gives you 30 days to respond. If you agree with the proposed changes, you pay the amount due. If you disagree, you must submit a written explanation and supporting documents showing why the IRS calculation is incorrect.

CP11, CP12, CP13: Math Error or Incorrect Calculation

These notices inform you that the IRS corrected a math error, adjusted your credits or deductions, or recalculated your tax. They are often straightforward, but if the IRS made a mistake—for example, disallowing a legitimate dependent or miscalculating the standard deduction—you have 60 days to dispute the adjustment.

Letter 525 or Letter 566: Examination (Audit) Notice

These letters notify you that the IRS has selected your return for examination. The letter will specify which tax year and which items the IRS wants to examine—common targets for physicians include Schedule C business expenses, home office deductions, vehicle expenses, charitable contributions above certain thresholds, and casualty loss claims. The notice will indicate whether the audit will be conducted by correspondence (you mail in documents) or in person at an IRS office or your place of business.

Notice of Deficiency (90-Day Letter)

If you did not respond to earlier notices or the IRS completed an audit and proposed additional tax, you may receive a statutory Notice of Deficiency. This notice gives you 90 days to petition the United States Tax Court if you disagree with the proposed deficiency. Missing this deadline means the IRS will assess the tax and begin collection, and your only recourse is to pay the full amount and file a refund claim.

CP14: Balance Due

A CP14 is the first notice that you owe tax. It may result from an adjustment, an audit, or simply an underpayment on your original return. Ignoring a CP14 leads to additional notices (CP501, CP503, CP504) and eventually a Notice of Intent to Levy.

What Not to Do When You Receive an IRS Notice

Mistakes in the first days after receiving a notice can complicate resolution and increase costs. Here are the most common errors physicians make:

• Ignoring the notice. The IRS does not forget. Each notice includes a response deadline, and if you do not respond, the IRS proceeds to the next step in the collection or examination process. Automatic assessments, liens, and levies can follow.
• Calling the IRS without preparation. The toll-free number on the notice may subject you to hold times exceeding an hour, and IRS phone representatives cannot provide tax advice or negotiate on your behalf. Anything you say can be used in the examination record.
• Sending incomplete or disorganized documentation. The IRS may disallow deductions if you cannot substantiate them with receipts, logs, or contemporaneous records. Dumping a box of receipts on an examiner does not satisfy the substantiation requirements under the Internal Revenue Code.
• Representing yourself in a complex audit. While you have the right to represent yourself, audits involving business income, multiple states, or significant deductions often require professional representation to protect your rights and present evidence effectively.
• Assuming the notice is always correct. The IRS makes mistakes. Third-party information returns can be wrong, IRS computers can misapply payments, and examiners can misinterpret the law. You have the right to dispute incorrect notices.

Who Can Represent You Before the IRS

Under IRS Circular 230, only three categories of professionals are authorized to represent taxpayers in all matters before the Internal Revenue Service:

• Certified Public Accountants (CPAs) licensed in any U.S. jurisdiction and in good standing may represent clients before the IRS in examinations, appeals, and collection matters.
• Enrolled Agents (EAs) are federally licensed tax practitioners who have passed a comprehensive IRS exam or worked for the IRS in a technical capacity for at least five years. Enrolled agents specialize in tax representation and are authorized to practice in all fifty states.
• Attorneys licensed in any U.S. jurisdiction and in good standing may represent clients before the IRS and can also provide legal advice on tax litigation, criminal tax matters, and Tax Court petitions.

Other professionals—including unlicensed tax preparers, financial planners, and wealth advisors—may prepare tax returns or provide general advice, but they cannot represent you in IRS proceedings unless they fall under a narrow exception (such as representing a taxpayer in connection with a return they prepared, and only for correspondence audits). If you receive an audit notice, engaging a CPA, enrolled agent, or tax attorney early can prevent costly missteps.

GenWealth 360 does not provide IRS representation services. We are a tax planning and wealth strategy firm, not a CPA firm, enrolled agent practice, or law firm. However, we work closely with physicians' existing CPAs and enrolled agents to organize records, analyze the tax planning decisions that may have triggered an inquiry, and coordinate a comprehensive response strategy. If you do not currently have a CPA or enrolled agent on retainer, we can help you understand the qualifications to look for and the questions to ask when selecting a representative.

How GenWealth 360 Helps Physicians Navigate IRS Notices

Our role is to support your existing tax professionals and ensure that the broader wealth and tax planning strategy remains intact during and after an IRS inquiry. Here is how we assist:

Document Organization and Substantiation

IRS examinations often hinge on documentation. We help physicians compile and organize receipts, mileage logs, appointment calendars, travel records, and business expense ledgers in a format that meets IRS substantiation standards. For W-2 versus 1099 income reporting issues, we work with your CPA to reconcile third-party information returns with your books and records.

Coordination with Your CPA or Enrolled Agent

If your return preparer is handling the IRS response, we coordinate with them to ensure that the strategy aligns with your long-term tax plan. For example, if the IRS is questioning S corporation reasonable compensation or home office deductions, we provide the broader context of your income streams, retirement contributions, and multi-year tax projections so your representative can present a complete picture.

Post-Audit Tax Planning

An IRS examination often reveals gaps in record-keeping, aggressive positions that lack support, or missed opportunities for legitimate deductions. After the audit closes, we work with you and your CPA to implement systems and strategies that reduce the likelihood of future inquiries. This may include better documentation protocols, adjustments to estimated tax payments, or restructuring income to align with advanced strategies for high earners.

Proactive Planning to Minimize Audit Risk

The best response to an IRS notice is to avoid receiving one in the first place. Our tax-first wealth architecture approach integrates income timing, entity structure, retirement plan design, and deduction planning to create a return that is both advantageous and defensible. We work with your CPA during the tax preparation process to ensure that every position is supported by contemporaneous documentation and a clear legal rationale.

Deadlines and Timelines You Must Know

IRS notices are time-sensitive. Here are the critical deadlines:

• CP2000: 30 days to respond, though the IRS may grant an extension if requested in writing before the deadline.
• Notice of Deficiency: 90 days (150 days if the notice is addressed to a taxpayer outside the United States) to petition the Tax Court. This is a statutory deadline and cannot be extended.
• Correspondence Audit: Typically 30 days to submit requested documents; extensions are often granted if you ask promptly.
• Collection Notices: CP14 and subsequent notices each give a window to pay or arrange a payment plan before the IRS issues a Notice of Intent to Levy. Once a levy is issued, the IRS can seize bank accounts, wages, and accounts receivable.

If you cannot meet a deadline, contact the IRS immediately or have your representative do so. Silence is interpreted as non-compliance, but a timely request for an extension is usually granted.

Special Considerations for High-Income Physicians

Physicians earning above the top marginal brackets face heightened scrutiny for several reasons:

• Multiple income streams: W-2 wages from a hospital, 1099 income from locum tenens, partnership distributions, rental income, and investment income create complexity and increase the chance of reporting mismatches.
• High deductions relative to income: The IRS uses statistical models (the Discriminant Function System, or DIF score) to flag returns with deductions that are unusually high for a given income level. Home office, vehicle, travel, and continuing education expenses for physicians often exceed the statistical norms for other professions.
• State and local tax cap: For 2026, the SALT deduction cap is $40,400, phasing down as modified adjusted gross income exceeds $505,000, and is scheduled to return to $10,000 in 2030. Physicians in high-tax states who claim the full SALT deduction may face questions about the calculation or the allocation between state income tax and property tax.
• Retirement plan contributions: Large contributions to solo 401(k) plans, defined benefit plans, or cash balance plans can trigger correspondence if the IRS questions whether the plan was established and operated correctly. Documentation of plan adoption, employee eligibility, and contribution calculations is essential.

How to Choose a Tax Professional for IRS Representation

If you receive an audit notice or a statutory Notice of Deficiency, selecting the right representative is critical. Here are the qualifications and questions to consider:

• Credentials: Verify that the professional is a CPA, enrolled agent, or attorney in good standing. Check the IRS Preparer Tax Identification Number (PTIN) directory and any applicable state licensing boards.
• Experience with physician tax issues: Representation requires familiarity with the specific deductions, income types, and entity structures common to physicians. Ask how many physician audits the representative has handled and what the outcomes were.
• Communication and availability: IRS deadlines are strict. You need a representative who will respond promptly to your questions and the IRS's requests.
• Fee structure: Some representatives charge hourly, others a flat fee for the full representation. Understand the scope of the engagement and what is not included (for example, appeals or Tax Court litigation may require separate agreements).
• Collaborative approach: If you have a wealth advisor, financial planner, or tax strategist already on your team, choose a representative who is willing to coordinate with them.
