The Taxpayer Bill of Rights: What to Do When the IRS Gets It Wrong

The IRS processed more than 271 million tax returns in 2023. With that volume, errors are not rare — they are statistically inevitable. For retirees navigating required minimum distributions, Roth conversions, and IRMAA surcharges, an incorrect IRS notice can trigger cascading financial problems if left unaddressed.

What many taxpayers do not know is that Congress enacted the Taxpayer Bill of Rights (TBOR) in 2014, codifying ten specific rights that apply in every IRS interaction. Knowing these rights — and how to use them — can be the difference between paying thousands of dollars you do not owe and protecting your retirement income.

Why retirees face more IRS friction

The retirement years come with income complexity that working years often do not: multiple 1099-Rs from IRA custodians, Social Security income with variable taxability, Roth conversion reporting, qualified charitable distributions (QCDs), and state pension income. Each of these is a potential data-matching mismatch between what you report and what third parties report to the IRS.

The three notices retirees most commonly receive in error:

CP2000 — IRS believes you under-reported income, often because a 1099-R was coded incorrectly by the custodian.
CP14 — IRS claims you owe a balance. Frequently triggered by RMD-related reporting differences.
Letter 531 — Statutory Notice of Deficiency. You have 90 days to respond before the proposed deficiency becomes final (confirm deadlines on your notice).

The most common scenario: a CP2000 after a Roth conversion

Janet's situation: Janet, 64, converted $55,000 from her traditional IRA to a Roth IRA in 2024. Her custodian issued a 1099-R showing the gross distribution but used distribution code "1" (early distribution) instead of a code that better reflects a Roth conversion or normal distribution context. The IRS automated matching system compared the 1099-R gross amount to Janet's return and issued a CP2000 proposing additional tax plus an early-distribution penalty — on income she had already correctly reported and for which no penalty applied.

Under the TBOR, Janet has the Right to Be Informed (the notice must explain the discrepancy) and the Right to Challenge the IRS's Position within the timeframe stated on the notice (often about 60 days for a CP2000 — verify your letter).

IRMAA recalculation disputes: Form SSA-44

A separate but related dispute situation arises with Medicare IRMAA. Social Security uses your MAGI from two years prior to set Part B and Part D premiums. If that year included a one-time large income event — a Roth conversion, a business sale, an inherited IRA distribution — and your income has since dropped, you can request a recalculation using Form SSA-44 (Medicare Income-Related Monthly Adjustment Amount — Life-Changing Event).

Qualifying life-changing events include:

Marriage, divorce, or death of a spouse
Work stoppage or reduction
Loss of income-producing property
Employer settlement payment (see SSA instructions for your situation)

A Roth conversion alone does not qualify as a life-changing event — but if the conversion coincided with your retirement (work stoppage), that event may qualify, and you can ask SSA whether a more recent tax year can be used.

What the Taxpayer Advocate Service can do

If you have received an incorrect notice and the standard response process is not working — the IRS is not responding, or a collection action is creating real financial hardship — you can request assistance from the Taxpayer Advocate Service (TAS), an independent organization within the IRS.

TAS can:

Issue a Taxpayer Assistance Order (TAO) requiring the IRS to stop certain collection activity when criteria are met
Expedite resolution of cases stuck in processing backlogs
Help resolve identity theft-related filing problems

To reach TAS: call 1-877-777-4778 or file Form 911 (Request for Taxpayer Advocate Service Assistance).

Common mistakes

Ignoring notices. A CP2000 is a proposal, not a final assessment — but silence is often treated as agreement. The response window on the notice matters.
Paying first, disputing later. Once you pay, recovering over-collected taxes may require an amended return (Form 1040-X), which can extend the timeline.
Not keeping Form 8606. If you have made non-deductible IRA contributions or track Roth conversion basis, Form 8606 matters. Without it, the IRS may lack your basis story.
Missing the Tax Court deadline. A Letter 531 (Statutory Notice of Deficiency) gives you a fixed period (often 90 days) to petition the U.S. Tax Court. Missing this deadline can foreclose Tax Court review — confirm the date on your notice.

💡 Insight

Do not assume a notice is correct because it looks official. Match every line to your custodian documents and your filed return before you pay.

What to know about Tax Court

The U.S. Tax Court has a Small Tax Case ("S case") procedure for disputes under a per-year dollar cap (historically discussed around $50,000; verify current limits and filing fees on the court site). Many S cases settle before a hearing. For larger amounts, a regular Tax Court case or a refund suit in federal district court may be appropriate — this is attorney territory.
