IRS Notice CP515 is a reminder concerning a tax return the IRS believes is missing. The IRS may have received income information connected to your Social Security number, such as Forms W-2 or 1099, but it does not have a corresponding Form 1040 for the tax year identified in the notice.
The notice does not automatically prove that you owe the amount the IRS may expect. It means the IRS wants the filing issue resolved. You may need to file the return, show that you already filed it, or explain why your income and circumstances did not require a return for that year.
CP515 is connected to an unfiled return, not a routine correction to a return already processed. It is also not the same as an audit notice. Still, leaving the notice unanswered can allow the IRS delinquent-return process to continue and can make the situation more difficult to correct later.
If you have more than one unfiled year, review your complete filing history rather than responding only to the year on the CP515. Resolving one notice may not close other filing gaps already recorded on your account.
Your response should match what actually happened. Filing another return without confirming the status of the first one can create duplicate-return complications, while ignoring the notice because you think you already filed may allow the case to advance.
Check the taxpayer name, Social Security number, tax year, notice date, response instructions, and mailing or fax information. Use the address, fax number, and deadline printed on your CP515 because IRS processing locations and instructions can differ by case. Keep the original notice with your records. If you send documents, retain complete copies of everything submitted and proof showing when and how you sent the response.
Determine if the return was never filed, filed and accepted, filed but rejected, or mailed without confirmation. If a tax professional prepared it, request the electronic filing acknowledgement rather than relying only on a copy marked “filed.” You can also review your IRS account information for the year involved. Account and wage and income transcripts may help show what the IRS received, what income was reported under your identification number, and if a return was posted.
Collect available Forms W-2, 1099, 1098, Schedule K-1, business income records, expense records, estimated-tax payment confirmations, and documents supporting deductions or credits. If documents are missing, wage and income transcripts can help identify information reported to the IRS, but they may not include every expense, basis figure, or state-tax detail needed to prepare an accurate return. For self-employed taxpayers, reconstructing income without reconstructing legitimate business expenses can overstate taxable profit. Bank records, invoices, bookkeeping files, payment-processor reports, receipts, mileage records, and prior-year files may help rebuild the return.
Your response will generally fall into one of four categories:
Do not select a response merely because it appears faster. The response should be supported by your filing records and the facts for that tax year.
Form 15103, Form 1040 Return Delinquency, is used to explain why the return is late, state that it was already filed, or explain why you were not required to file. Complete the form accurately and make sure the identifying information matches the notice. If you are submitting the missing return, sign and date it and include the completed response form as instructed. For a joint return, verify all required signatures before sending the package.
Send the return, Form 15103, and any requested supporting documents to the location shown on your notice. The IRS states that applicable returns from the two most recent prior years may be eligible for electronic filing through a provider that offers prior-year e-filing, while older returns may need to be mailed. If the notice permits a fax response, use the fax number printed on the notice. Protect sensitive tax information when using an online fax service, and keep the transmission confirmation with your records.
Allow time for the IRS to process the response, then verify that the return and any related correspondence were applied to the correct tax year. Keep watching for additional IRS mail because a later letter may request clarification or indicate that the response has not yet been associated with the account. If a new notice arrives while the return is being processed, compare its date with your submission date. Do not assume that the new correspondence is irrelevant, but do not automatically resend everything without checking the account status.
Start by confirming that the IRS accepted or received the return. For an electronic filing, locate the acceptance acknowledgement. For a paper filing, find the certified-mail receipt, tracking information, or other delivery confirmation.
The IRS currently states that no additional action may be necessary if the return was filed within the last eight weeks. If more than eight weeks have passed, or the return does not appear on the account, complete Form 15103 and follow the notice instructions for providing a signed and dated copy.
Check that the taxpayer name, Social Security number, and tax year on the return match the CP515. A mismatch can prevent the return from posting correctly even when it reached the IRS.
Avoid filing a second return electronically or mailing another original without first determining what happened to the initial submission. A tax professional can review transcripts and filing records to help choose the correct response.
Do not ignore CP515 simply because you believe no return was required. The IRS sent the notice because its information indicates that a filing requirement may exist, so it needs an explanation before it can resolve the discrepancy.
Complete Form 15103 and state why you were not required to file for the tax year shown. Your explanation may depend on filing status, age, gross income, self-employment income, dependency status, or another filing rule applicable to that year.
Use the rules for the specific tax year rather than current-year thresholds. Filing requirements can change, and special rules may apply to self-employment income, advance premium tax credits, retirement-account transactions, household employment taxes, and other circumstances.
File the return even if you cannot pay the full balance. Delaying the return because payment is unavailable can add filing-related penalties and gives you less control over the figures used to calculate the liability.
Paying what you reasonably can with the return may reduce the balance on which future penalties and interest accrue. After the return is processed, the appropriate next step may include an installment agreement, Currently Not Collectible status, an Offer in Compromise, or another resolution based on the account and your financial circumstances.
These programs have different eligibility requirements and consequences. Review the full account before choosing an option, especially if several years are unfiled or more than one tax period has a balance.
The filing issue does not disappear when CP515 goes unanswered. The IRS may continue sending delinquent-return notices, including a final reminder such as Notice CP518, and may eventually calculate a proposed tax amount using income information reported by employers, financial institutions, and other third parties.
That calculation may not reflect all deductions, credits, expenses, basis information, dependents, or filing choices available on a properly prepared return. A later Notice CP2566 can show tax, penalties, and interest calculated from the information available to the IRS and give you a limited period to respond.
An unfiled return can also delay a refund from another year. Penalties and interest may continue to accrue when tax is due, and unresolved filing requirements can limit access to certain collection alternatives.
The sooner the filing record is corrected, the more opportunity you have to provide complete information before the IRS moves further through its process. You can see how these notices fit together on the IRS collection process timeline.
For individuals and most business returns, the IRS generally calculates the failure-to-file penalty at 5% of the unpaid tax for each month or part of a month the return is late, up to 25%. When the failure-to-file and failure-to-pay penalties apply during the same month, the failure-to-file penalty is reduced by the failure-to-pay penalty for that month.
Different rules and amounts apply to certain partnership, S corporation, and information returns. The calculation also depends on the tax year, the return type, payments already made, available credits, and the length of the delay.
Penalty relief may be available when the taxpayer meets the IRS requirements for reasonable cause or another relief provision. A request should be supported by the actual facts and records, not a general statement that filing was difficult. Our IRS penalty abatement page explains common forms of penalty relief in more detail.
Several IRS notices can concern an unfiled Form 1040, but they do not all represent the same point in the process. Read the notice number and response instructions carefully rather than treating every delinquent-return letter as interchangeable.
| Notice | What it covers | What it means for your response |
|---|---|---|
| CP59 | The IRS says it has no record of a required return | Confirm the filing requirement and respond with the return or an explanation |
| CP515 | Reminder that the return is still missing | Resolve the filing status and use Form 15103 as instructed |
| CP518 | Final reminder that the IRS still has no return | Respond immediately before the IRS takes further action based on available information |
| CP2566 | The IRS calculated proposed tax, penalties, and interest because it did not receive the return | File your return or respond to the proposed amount by the date shown |
IRS records do not always update as quickly as taxpayers expect, but silence is not a response. If the return was filed, preserve the acceptance or delivery proof and follow the CP515 instructions when the filing is not reflected after the processing period stated by the IRS.
A rushed return based only on incomplete documents may omit income, expenses, deductions, or payments. Reconstruct the year carefully and compare available records with IRS transcripts before submitting figures that will become part of the account.
The filing obligation and the payment obligation are separate. File an accurate return first, then address the balance through the payment or resolution option that fits your circumstances.
The address used for an ordinary tax return may not be the address assigned to your CP515 response. Follow the notice instructions and include the requested response form so the IRS can associate the package with the correct case.
CP515 may identify one year even though other returns are also missing. Review the full filing history so that resolving one year does not leave another delinquent-return issue ready to generate a new notice.
If you say the return was filed, provide the filing date and available proof. If you say no return was required or that third-party income is incorrect, provide a clear explanation and relevant supporting documentation.
Responding to CP515 may involve more than mailing a return. We can help review the notice, check the filing history, obtain and analyze available transcripts, identify missing records, and determine which response fits the account.
When a return is missing, our team can help organize the steps needed to bring the filing record current and evaluate the balance after the return is processed. If the completed return creates a tax liability that cannot be paid in full, we can also review available tax relief services and explain the requirements for each option.
The objective is to give the IRS a complete, accurate response while protecting your ability to address the balance through an appropriate resolution. We do not rely on assumptions about what the IRS has on file; we start with the notice, the account records, and the facts for the tax year involved.
CP515 means the IRS has no record of a prior-year tax return that it believes you were required to file. You need to file the return, confirm that it was already filed, or explain why you were not required to file.
CP515 concerns a missing return and is not, by itself, a final tax assessment. Filing the return may produce a balance, a refund, or no tax due, depending on the accurate figures for that year.
Use the response date shown on your CP515 rather than relying on a general deadline found online. Notice dates and case instructions can differ, so send the requested response as soon as you can prepare it accurately.
Form 15103 is the IRS response form for a Form 1040 return delinquency. It allows you to explain why the return is late, state that it was already filed, or explain why you were not required to file.
Confirm that the return was accepted or delivered and keep the supporting record. The IRS states that no additional action may be necessary if you filed within the last eight weeks, but you should follow the instructions on your CP515 if the return still does not appear or another notice arrives.
The available response method depends on what you need to submit and the instructions on the notice. The IRS indicates that taxpayers who are submitting only Form 15103 to explain why no return was required may be able to submit it online through an IRS Online Account.
The IRS allows a fax response when the notice provides a fax number and directs you to use it. Follow the number on your CP515, protect the sensitive information being transmitted, and keep the fax confirmation.
IRS wage and income transcripts may help identify forms reported under your Social Security number. They may not contain every detail needed for an accurate return, so you may also need bank records, employer records, business files, or other documentation.
Yes, an inability to pay does not remove the filing requirement. File the accurate return, pay what you reasonably can, and then evaluate payment plans or other resolution options for the remaining balance.
The IRS can use available third-party information to calculate tax when a required return remains unfiled. That calculation may not include all deductions, credits, expenses, or other facts that could appear on a return you prepare and file yourself.
No, CP515 is a delinquent-return notice rather than an examination notice. Filing a late return does not prevent the IRS from reviewing it later, but receiving CP515 does not itself mean an audit has begun.
An eligible tax professional can communicate with the IRS after the required authorization is completed. We can review the notice and explain what authorization and representation may be available for your situation.
CP515 is a chance to correct the filing record before the IRS proceeds further with the information it already has. A clear response can show that the return was filed, establish that no return was required, or place an accurate late return on the account.
