Why it matters
A medical emergency can create a clear, time-limited inability to meet tax filing or payment obligations. The IRS considers requests for penalty relief under categories such as reasonable cause and first-time abatement when documentation shows the taxpayer couldn’t comply because of circumstances beyond their control (IRS guidance on penalty relief).
Quick checklist (what to collect first)
- Official medical records with dates of service (hospital admission/discharge, surgery reports).
- Itemized medical bills and statements showing balances and payments.
- Physician or provider letter describing the condition, incapacitation period, and how it prevented tax compliance.
- Insurance claims, Explanation of Benefits (EOBs), and denial letters.
- Proof of missed income (pay stubs, employer leave records) or medical leave documentation.
- Bank statements, canceled checks, or payment transaction records showing efforts to pay taxes or make payments when possible.
- Copies of IRS notices or penalty assessments (attach the letter you received).
Step-by-step documentation process
-
Create a concise timeline: list key dates (onset of illness, admission, surgery, recovery milestones, missed tax deadlines). A clear timeline ties the emergency to specific missed obligations.
-
Get a provider statement: request a short signed letter from the treating physician or hospital that confirms diagnosis, treatment dates, and capacity to manage finances or file taxes.
-
Gather financial proof: show how medical costs or lack of income reduced ability to pay. Include medical bills, EOBs, proof of assets used for care, and records of partial payments to the IRS.
-
Prepare a reasonable-cause letter: explain what happened, reference the dates in your timeline, list attached documents, state the relief requested (abatement of penalties, refund request), and include identifying information (taxpayer name, SSN or ITIN, tax year, type and amount of penalty).
-
Choose the correct submission method: attach your documentation and letter when responding to an IRS notice (use the address on the notice) or submit through your IRS online account when the option is available. In some cases, taxpayers also use Form 843 (Claim for Refund and Request for Abatement): see the IRS Form 843 instructions before using it (IRS—About Form 843).
Sample reasonable-cause letter outline
- Header: taxpayer name, SSN/ITIN, tax year, IRS notice number.
- One-paragraph summary of the medical emergency and the tax consequence.
- Timeline with key dates and actions taken.
- List of attached evidence (medical records, bills, physician letter, bank statements).
- Closing request for penalty abatement and contact information.
How the IRS evaluates documentation
The IRS looks for credible, contemporaneous evidence that the medical emergency directly prevented compliance and that the taxpayer acted reasonably under the circumstances. Routine medical bills alone are usually not enough—connect the medical events to missed filing or payment with dated records and an explanatory timeline (see IRS penalty relief guidance and reasonable-cause criteria).
Practical tips from practice
- Order records early: hospitals and providers can take weeks to produce complete records.
- Redact unrelated personal health details not needed to establish dates and incapacity.
- Keep the package organized: use a table of contents and label exhibits (Ex. A, Ex. B).
- If you used a tax pro or power of attorney, include Form 2848 or a signed authorization so the IRS can discuss the case with them.

Common mistakes to avoid
- Relying only on unpaid bills without a physician statement or a timeline.
- Missing the IRS notice deadline—respond to the address on the notice and include the notice number.
- Submitting disorganized evidence; the clearer the package, the easier it is for an examiner to see the connection.
What to expect after you submit
Processing times vary: simple requests may resolve in several weeks, while complex cases can take months. The IRS may request additional information or schedule a review. Keep copies of everything you send and use certified mail if mailing original documents.
