IRS Notice CP71C is an annual reminder that the IRS believes you still have an unpaid balance for a specific tax year. It’s not usually the first letter you’ve received about the debt—it’s the IRS checking in again and showing what’s still outstanding.
Because CP71C is tax-year specific, you may receive more than one CP71C if you owe for multiple years.
This notice is also tied to a legal requirement. Internal Revenue Code § 7524 requires the IRS to send written delinquency notices at least annually to taxpayers with delinquent accounts.
The good news: CP71C is often a “reminder stage” letter. If you respond thoughtfully—by verifying the balance and choosing a workable resolution—you can usually prevent the account from getting more expensive or moving closer to enforced collections.
IRS Notice CP71C At a Glance
- Letter type: Annual reminder to an individual about a balance due
- Generated by: IRS service center
- Why you’re getting it: The IRS shows an unpaid balance for the listed tax year
- Typical message: Pay by the deadline or make arrangements (options may include a payment plan or other relief)
- Common warning included: Passport certification rules for “seriously delinquent tax debt” may be explained in the notice
IRS Notice CP71C Explained, Part by Part
Part 1: Billing summary
The first page usually includes a line-by-line snapshot of what the IRS says you owe for that tax year—typically separating:
- Tax
- Penalties
- Interest
- Total amount due
If your records don’t match the notice, don’t assume you’re wrong. Payments can post late or be applied to the wrong year, and credits sometimes don’t show up the way taxpayers expect.
Part 2: Payment coupon
CP71C often includes a payment stub you can mail with a check or money order.
Even if you pay online, keep the notice and save proof of payment (confirmation number, bank record, date and amount).
Part 3: What the IRS wants you to do
The IRS’s core instruction is simple: pay the balance or contact the IRS to discuss how you’ll resolve it. The notice typically includes a “pay by” date and contact details.
If you already have an approved resolution in place, the correct move may simply be staying compliant and continuing that plan—but you still want to confirm the notice matches your current status.
Part 4: Passport denial or revocation information on IRS Notice CP71C
CP71C commonly includes a section explaining the passport rules under IRC § 7345 for taxpayers with “seriously delinquent tax debt.”
The threshold is adjusted annually for inflation. The IRS publishes the current amount (for example, the IRS list shows $64,000 for 2025 and $66,000 for 2026).
Important: Not every balance due triggers passport issues. Passport certification generally involves a high balance and additional conditions the IRS describes in its guidance.
Part 5: Payment options overview
CP71C usually points you toward ways to resolve the debt—commonly:
- Paying in full
- Setting up a payment plan
- Exploring other resolution programs if you qualify
Part 6: What happens if you don’t respond
This section generally warns that:
- Penalties and interest may continue
- The IRS can keep sending reminder notices
- A Notice of Federal Tax Lien may be filed in some cases
CP71C is not the same as a final levy notice, but ignoring IRS balance notices makes escalation more likely over time.
Part 7: Additional information and recordkeeping reminders for your IRS Notice CP71C
Near the end, you’ll usually see standard reminders about:
- How to contact the IRS
- Where to get forms/publications
- Keeping the notice for your records
When the IRS Sends Notice CP71C
The IRS sends CP71C when it still shows an unpaid balance for a tax year and the account remains unresolved. CP71C is also part of how the IRS satisfies the annual reminder requirement described in IRC § 7524.
And yes—some taxpayers receive other reminder notices in addition to CP71C during the year (for example, LT39).
What You Should Do If You Receive CP71C
Step 1: Verify the tax year and the balance on IRS Notice CP71C
Start by confirming:
- The tax year on the notice matches the year you think is in question
- The balance reflects your payments, refunds applied, and any recent filings
If you owe multiple years, handle CP71C notices one year at a time so nothing gets missed.
Step 2: Check for posting errors or missing credits
Common “false balance” causes include:
- Payments applied to the wrong year
- A payment made recently that hasn’t posted yet
- Credits that didn’t carry over the way you expected
If you think the IRS is wrong, gather proof (bank records, payment confirmations) before you call.
Step 3: Choose a realistic resolution option
Your best next move depends on cash flow and how much you owe:
- Pay in full if you can (fastest way to stop the balance from growing)
- Installment agreement if you can pay over time
- Offer in Compromise if you may qualify to settle for less than the full amount
- Currently Not Collectible (CNC) if paying would create significant financial hardship
The goal is a solution you can actually maintain—because defaulting on an agreement can restart the cycle.
Step 4: Respond promptly and keep a paper trail
Whether you pay, call, or apply for a program, document everything:
- The notice
- Proof of payments
- Notes from calls (date, time, agent info, what was said)
- Copies of submissions
If you’re not sure which path fits, that’s the moment to bring in professional support.
