IRS CP71A Notice: Annual Balance Due Reminder — Practitioner Response Guide
The CP71A is an annual reminder notice sent to taxpayers who have an outstanding balance with the IRS. It is not a new assessment — it is a status update on an existing debt, showing the current balance including accrued interest and penalties. Practitioners receive this notice frequently for clients on installment agreements or who have unresolved balances. This guide explains what the notice means, how to verify the balance, and how to use it as a planning trigger.
What the CP71A Is — and What It Is Not
The CP71A is a routine annual balance reminder. It is not a new assessment, not a notice of deficiency, not a levy notice, and not a demand for immediate payment. The IRS sends it annually to taxpayers with unresolved balances to ensure they are aware of the current amount owed, including interest and penalties that have accrued since the original assessment.
The notice shows: the tax year(s) with outstanding balances, the original tax assessed, penalties assessed (failure-to-file, failure-to-pay), interest accrued through the notice date, and the total amount currently owed. Because interest accrues daily under IRC §6601 and the failure-to-pay penalty accrues monthly under §6651(a)(2), the balance shown on the CP71A will be higher than any previous notice the client received.
Practitioners should use the CP71A as an annual planning trigger for clients with unresolved balances: verify the balance against the IRS account transcript, confirm the collection statute expiration date (CSED), evaluate whether an offer in compromise or installment agreement modification is appropriate, and advise the client on the ongoing cost of carrying the balance (interest + penalty accrual).
How to Verify the Balance Shown on CP71A
The balance on the CP71A is calculated as of the notice date. To verify it, pull the client's IRS account transcript (IMFOL or BMFOL for business accounts) and compare the assessed tax, penalties, and accrued interest. Common discrepancies include: payments made after the transcript date that are not reflected, abated penalties that the IRS has not yet applied, and interest calculation errors (rare but possible).
If the client has an active installment agreement, the CP71A balance should reflect payments made under the agreement. If it does not, the client's payments may not be properly credited — contact the IRS Automated Collection System (ACS) at 1-800-829-7650 to verify payment application.
The Cost of Carrying an IRS Balance: Interest + Penalty Math
The federal short-term rate plus 3 percentage points determines the underpayment interest rate under IRC §6621. In 2026, the underpayment rate is 8% (annualized), compounding daily. The failure-to-pay penalty under §6651(a)(2) accrues at 0.5% per month (up to 25% of the unpaid tax). Combined, a client carrying a $50,000 balance is accruing approximately $4,000/year in interest plus $3,000/year in failure-to-pay penalty — $7,000/year in carrying costs on a $50,000 balance. Resolving the balance through an offer in compromise, borrowing to pay, or accelerating installment payments is almost always more cost-effective than carrying the balance.

Verify the notice is legitimate by checking the notice number and comparing it to your filed return. Do not ignore it — most IRS notices have strict response deadlines. Pull your IRS account transcript online at IRS.gov to confirm the assessment matches what the IRS shows on file.
Most IRS notices require a response within 30 days from the date printed on the notice. Some notices, like statutory notices of deficiency, give you 90 days. Missing the deadline can result in default assessments, loss of appeal rights, or escalation to collection action including liens and levies.
Yes. First-time penalty abatement (FTA) is available if you have a clean three-year compliance history — meaning you filed all required returns on time and paid all taxes due for the prior three years. You can request FTA by calling the IRS at 1-800-829-4933 or by submitting a written request.
You have the right to dispute any IRS assessment. File a written protest within the response window explaining why you disagree, attach supporting documentation, and request a conference with IRS Appeals. If the amount is under $25,000, you can use the simplified Collection Due Process (CDP) hearing request.
Yes. The IRS offers installment agreements for taxpayers who cannot pay in full. For balances under $50,000, you can apply online at IRS.gov/OPA. For larger balances, you will need to submit Form 9465 along with Form 433-A (Collection Information Statement) documenting your income and expenses.
An IRS notice alone does not affect your credit score. However, if the balance remains unpaid and the IRS files a federal tax lien (Notice of Federal Tax Lien), that lien becomes a public record and can significantly damage your credit. Paying or resolving the balance before lien filing protects your credit.
For simple issues like verifying a payment or correcting a minor discrepancy, calling 1-800-829-4933 is faster. For complex disputes, penalty abatement requests, or anything involving legal arguments, always respond in writing via certified mail with return receipt so you have proof of timely response.
Yes. Your CPA, EA, or tax attorney can represent you before the IRS using Form 2848 (Power of Attorney). Once filed, the IRS will communicate directly with your representative. This is strongly recommended for notices involving audits, large balances, or potential criminal referrals.
Ignoring an IRS notice triggers an escalation sequence: the IRS will send follow-up notices (CP501, CP503, CP504), then a final notice of intent to levy (LT11 or CP90). After the final notice, the IRS can levy bank accounts, garnish wages, and seize property without further warning.
Yes. The IRS generally has 10 years from the date of assessment to collect a tax debt (the Collection Statute Expiration Date or CSED). After 10 years, the debt expires and the IRS can no longer collect. However, certain actions — like filing an Offer in Compromise or requesting a CDP hearing — can toll (pause) the statute.
Penalties can be abated through FTA, reasonable cause, or statutory exception. Interest, however, is almost never abated — the IRS is required by law to charge interest on unpaid tax from the due date until the date of payment. The only way to stop interest from accruing is to pay the underlying tax balance.
