DTF-948 / DTF-948-O, Request for Missing Information Notice series

You received Form DTF-948 or DTF-948-O because the New York State Department of Taxation and Finance needs documents to verify something you reported on your personal income tax return before it finishes processing your return or releases your refund. This is a request for information letter, not a bill. The state is holding the return open while it confirms an item it cannot match against the records it already has. New York explains this directly on its Respond to a letter requesting additional information page at tax.ny.gov, which lists DTF-948 and DTF-948-O as the primary letters used to request return support.

The most common reasons fall into a few buckets. The state may want to verify that you reported the correct amount of wages and withholding for New York State, New York City, or Yonkers, which usually means it wants copies of your W-2 forms and 1099 forms. It may want to confirm that you lived or worked in New York, New York City, or Yonkers during the year, which goes to residency and the right rate. It may have processed a return where you claimed a credit or a tax benefit but the supporting form did not arrive with the return, so it needs the form before it can allow the credit. It may also want proof behind an itemized deduction or eligibility for a refundable credit such as the Empire State child credit or the earned income credit.

Here is a worked example. Suppose you filed your 2025 New York return on March 3, 2026, claiming 14,200 dollars of New York withholding and a 1,500 dollar refund. Your employer reported a different withholding figure on the wage file it sent the state, or the file arrived late. New York cannot match your 14,200 dollar number, so it issues a DTF-948 dated April 10, 2026, asking for your W-2. You upload the W-2 showing box 17 state withholding of 14,200 dollars, and the return clears.

A common mistake is treating the letter as junk mail or as proof that you did something wrong. Neither is true. The state simply could not verify a number on its own, and a quick, matching document usually closes the file. A further note on timing. New York issues these letters during the period it is actively reviewing returns, so a fast answer keeps your file in the active queue rather than pushing it to a later batch. Refunds that clear verification typically move within a few weeks of a complete response, while an incomplete answer can send the file back to the bottom of the stack. Another mistake is sending your entire tax folder. Send the item the letter names, not everything you own.

An edge case worth knowing. You may see the request appear in your online refund status before the paper letter reaches your mailbox. The mail can lag the electronic notice by a week or more. If your refund status tells you a letter was sent, you do not have to wait for the envelope. You can read and answer it inside your Individual Online Services account.

If you are not sure which item triggered the letter or how to document it, a short call with a CPA can save weeks. The Reed Corporation can read the notice with you and identify the exact proof New York wants. Start at reedcorp.tax/new-client-inquiry.

The first move after receiving a DTF-948 or DTF-948-O is to read the letter from top to bottom and find the response date, then match the request to the return you filed. Do not pay anything. This is not a bill, and there is usually nothing to pay. The letter is asking for documents so the state can finish processing your return. The wrong first step is responding before you understand which item is in question, because a vague or mismatched response can stall the refund longer than the original request would have. One more practical step. Before you upload anything, confirm the figure on the letter against the figure on your filed return, then against the source document, so all three agree. If they do not agree, you have found the real issue, and you can explain the difference in a short cover note rather than leaving the reviewer to guess.

Start by writing down four things from the face of the letter. The date on the notice, the response deadline, the tax year, and the specific item the state wants to verify. New York lists the categories on its Respond to a letter requesting additional information page at tax.ny.gov. The letter will point you to one of them, such as wages and withholding, residency, a claimed credit, or an itemized deduction. Once you know the category, pull the matching proof. For wages and withholding, that is your W-2 and any 1099 forms. For a credit, it is the credit form that should have ridden along with the return. For residency, it can be a lease, utility bills, or an employer letter showing where you worked.

The fastest channel is online. Log in to your Individual Online Services account and open the Respond to Department Notice application. You can view the letter and upload your documents in the same place. The federal system works the same way for IRS notices. The IRS Document Upload Tool lets you respond to an IRS letter electronically rather than by mail, described at irs.gov, and the IRS general guidance on responding to a notice is at irs.gov.

Here is a worked example. You receive a DTF-948 dated May 5, 2026, with a response date of June 4, 2026, asking you to verify the 3,300 dollars of Empire State child credit you claimed for two children. You log in on May 8, 2026, upload the completed Form IT-213 plus the children Social Security cards, and the file clears in three weeks. Had you waited, the refund would have sat until you answered.

A common mistake is missing the date because the letter looked like marketing. Calendar the response date the day you open the envelope. An edge case. If the document the state wants no longer exists, such as a W-2 from a closed employer, you can request a wage and tax statement from the IRS or ask the employer for a reissue, and you should note that in your response so the reviewer knows why the proof differs.

If the timeline is tight or the item is unusual, get help early. The Reed Corporation can organize the response and submit it cleanly. Begin at reedcorp.tax/new-client-inquiry.

Yes. The Reed Corporation can turn a DTF-948 or DTF-948-O into a short, clear response that a New York reviewer can approve without follow up questions. The work is practical. We read the letter, identify the exact item the state wants to verify, pull the return you filed, locate the matching proof, and assemble a package that answers the point and nothing else. New York request for information letters reward focused responses and punish confusion, so the goal is a clean match between the letter and the documents. We also keep a copy of everything we submit and the confirmation the state returns, so if the refund is delayed you have a dated record of exactly what was sent and when. That record settles most follow up questions in a single reply. We also confirm whether the same return triggered a parallel federal hold, because catching both at once means one coordinated response instead of two scattered ones. If a federal letter is open, we line up the same proof for both reviewers so the W-2 or credit form you already pulled does double duty.

A typical engagement runs like this. First, we read the notice and confirm the category. New York lists the categories of these letters on its Respond to a letter requesting additional information page at tax.ny.gov, and the letter itself points to one of them, such as wages and withholding, residency, a claimed credit, or an itemized deduction. Second, we compare the figure on the letter to the figure on the return and to the underlying source document, such as the W-2 in box 17 for state withholding. Third, we build the upload set and submit it through your Individual Online Services account using the Respond to Department Notice tool. Fourth, we track the refund status until the return clears.

We bring the same approach to the federal side when a parallel IRS letter shows up, because identity and refund verification requests often arrive in both systems for the same return. The IRS describes how it verifies returns and identity to protect refunds at irs.gov, how to read and respond to a notice at irs.gov, and how to upload documents electronically through the IRS Document Upload Tool at irs.gov.

Here is a worked example. A client filed a 2025 return claiming 9,400 dollars of New York withholding across two jobs and a 2,100 dollar refund. New York issued a DTF-948 dated April 18, 2026, because one employer wage file posted late. We pulled both W-2 forms, confirmed box 17 totaled 9,400 dollars, uploaded both on April 22, 2026, and the refund posted three weeks later with no reduction.

A common mistake taxpayers make before calling us is sending unrelated documents, which invites new questions. We send only what answers the point. An edge case we handle often is a credit form that never attached to the e-filed return. The credit was valid, the form simply did not transmit, so we resubmit the form and the credit stands.

The documents you gather for a DTF-948 or DTF-948-O should match the exact item the letter names. Do not send your whole tax folder. Send the proof that answers the point New York raised. A focused package is faster for a reviewer to process, and it avoids creating new questions from unrelated material. One more tip on formatting. Label each file plainly, for example W2 Acme 2025 or IT-213 Empire State child credit, so the reviewer can tell at a glance that the document answers the letter. Clear labels move a file through review faster than a stack of unnamed attachments. The state lists the verification categories on its Respond to a letter requesting additional information page at tax.ny.gov, and the letter itself tells you which one applies.

If the letter asks you to verify wages and withholding, gather every W-2 for the year and any 1099 forms that show New York withholding, such as a 1099-R or 1099-NEC. The number that matters most is box 17 on the W-2, the state income tax withheld, because that figure has to support the withholding you claimed on the return. If the letter asks about residency, gather proof of where you lived and worked, such as a lease or mortgage statement, utility bills in your name, or a letter from your employer stating your work location. If the letter asks about a credit, gather the credit form that should have accompanied the return, for example Form IT-213 for the Empire State child credit or Form IT-215 for the New York earned income credit, plus the records that prove eligibility, such as Social Security cards or dependent records. If the letter asks about an itemized deduction, gather the receipts, statements, or canceled checks behind the amount.

For the federal analog, the IRS asks for the same kind of targeted proof when it requests documents, and you can submit it through the IRS Document Upload Tool described at irs.gov. The IRS general instructions for responding to a notice are at irs.gov, and its identity and return verification process, which often runs alongside a refund hold, is at irs.gov.

Here is a worked example. Your letter, dated March 28, 2026, asks you to verify 6,800 dollars of New York City withholding. You gather one W-2 showing box 17 of 6,800 dollars and box 19 local withholding, upload it on April 1, 2026, and the return clears. You do not include your bank statements or prior year returns, because the letter did not ask for them.

A common mistake is sending screenshots that cut off names, dollar amounts, or the year. Send the full document, legible, with the tax year visible. An edge case. If your only W-2 is missing because the employer closed, you can request a wage transcript from the IRS or a wage statement, and you should label it so the reviewer understands the substitute.

If you are unsure which document proves your point, The Reed Corporation can map the letter to the right records before you submit. Start at reedcorp.tax/new-client-inquiry.

Ignoring a DTF-948 or DTF-948-O is usually the worst choice, because the letter is the only thing standing between you and a finished return. New York holds the return open while it waits for the documents it asked for. If you do not respond by the date on the letter, the state finishes the return using only the records it already has, which often means it disallows the item it could not verify and adjusts your refund or balance accordingly. New York states on its Respond to a letter requesting additional information page at tax.ny.gov that you should respond by the date noted on the letter so it can continue processing your return.

Walk through what that adjustment looks like. Say you claimed a 2,400 dollar refund driven by 12,000 dollars of withholding and a 1,000 dollar credit. The DTF-948 asked you to verify the withholding and the credit. You do nothing. The state cannot confirm those figures, so it removes the unverified amounts and recomputes the return. Your 2,400 dollar refund can shrink, disappear, or flip into a balance due. Now you are no longer answering a simple document request. You are disputing a changed return, which is slower and harder, and any balance the state creates can begin to accrue interest. One more reason to act. Once the state changes your return, getting the original refund back often means a separate review or a formal request, and that path runs on the state timeline rather than yours. Answering the first letter on time keeps the matter inside the simple document channel where it belongs.

The federal system behaves the same way. When the IRS holds a refund for verification and you do not answer, it can adjust the return and issue a different notice. The IRS explains how to read and respond to its notices at irs.gov, runs an identity and return verification process that can freeze a refund until you respond at irs.gov, and lets you submit your documents through the IRS Document Upload Tool at irs.gov. Answering the request is almost always faster than fighting an adjustment later.

Here is a worked example with dates. A letter dated February 20, 2026, sets a response date of March 22, 2026, and asks you to verify your wages. You miss it. In May 2026 the state issues a refund adjustment removing the unverified withholding, and your 2,400 dollar refund becomes a 300 dollar balance. You now have to gather the same W-2 you could have sent in February and submit it as part of a dispute, with the clock already running.

A common mistake is assuming the letter is informational and carries no deadline. Many of these letters do carry a response date, and the date controls. An edge case. Even after a deadline passes, you are usually better off responding than staying silent, because a late but complete document set can still get the item reviewed.

Do not let the date slip. If you are close to the deadline or already past it, The Reed Corporation can help you respond and pursue the refund. Start at reedcorp.tax/new-client-inquiry.
