How to Read an IRS Notice: What Seniors Need to Know

Receiving a letter from the IRS is stressful for most people — and particularly for retirees on fixed incomes who worry about what a tax bill or audit could mean for their financial security. The first thing to understand is that most IRS notices sent to older Americans are not demands for immediate payment. Many are routine notifications that require a simple response, and several can be disputed or resolved without paying anything.

The IRS sends several million notices to seniors each year. The most common ones relate to underreported income (typically from 1099-R distributions or Social Security), balance-due amounts from prior-year returns, and enforcement actions — levies and liens — that the IRS pursues only after earlier notices have gone unanswered.

The Five Notices Seniors Receive Most Often

• CP14 — A balance-due notice telling you the IRS believes you owe money. This is the first notice in the collection sequence. You have 21 days before interest begins accruing. Use our CP14 Notice Decoder to verify the amount and see your options.
• CP2000 — An "underreporter inquiry" proposing additional tax because income reported on your return does not match what payers reported to the IRS. This is not a bill yet — it is a proposal you can accept, partially accept, or dispute within 30 to 60 days.
• CP504 — A final balance-due notice that warns the IRS intends to levy your state tax refund if you do not pay or respond. Unlike the CP14, the CP504 has real enforcement consequences if ignored.
• LT11 — A final notice of intent to levy your wages, bank accounts, or other assets. Receiving an LT11 means you have 30 days to request a Collection Due Process hearing or pay in full. After 30 days the IRS can proceed without further notice.
• CP90 — Similar to the LT11, the CP90 is a formal intent-to-levy notice with Collection Due Process rights. It is typically sent for the same collection cycle. Use our CP90 Notice Decoder to understand your exact rights and deadlines.

The Single Most Important Rule

Never ignore an IRS notice. The collection sequence is designed so that each unanswered notice escalates to a more serious enforcement action. A CP14 ignored becomes a CP504, which ignored becomes an LT11 or CP90, which — if ignored — leads to an actual levy on your Social Security, bank account, or wages. The IRS can levy up to 15% of Social Security retirement benefits under the Federal Payment Levy Program.
