Most lenders already know what belongs on Form 1098-VLI. The friction is getting accepted electronic filings to the IRS before the March deadline — and keeping borrower copies on the separate January clock.
IRIS (Information Returns Intake System) is the IRS’s modern channel for many information returns, including 1098-VLI for lenders who must e-file. This guide is the how-to: account setup, submission paths, typical validation failures, and how to read acceptance status. Statutory backdrop: §6050AA compliance. Dates: filing deadlines.
Official hub: IRS IRIS and About Form 1098-VLI.
What IRIS does
IRIS replaces the aging FIRE flat-file workflow for forms the IRS has migrated. For Form 1098-VLI in the 2026 interest / early 2027 filing cycle, plan on IRIS (or a vendor that submits through IRS-approved electronic channels) — not “email a spreadsheet to someone in compliance.”
This guide focuses on the paths most lenders actually run day to day:
- Taxpayer Portal — enter each return in the browser (works for smaller counts).
- Application-to-Application (A2A) — your loan system sends returns to IRIS via XML/API (high volume; requires assurance testing before production).
The IRIS dashboard and IRS publications describe other electronic submission options as well; use whatever method your volume and systems fit, as long as the IRS accepts the transmission. IRIS validates many issues at submission, which beats waiting days for a FIRE error file — but it also means bad data gets rejected immediately.
Who must file through IRIS (or e-file generally)
You need Form 1098-VLI when you receive $600+ of SPVL interest on one loan in a calendar year in the course of a trade or business. That includes banks, credit unions, captives, dealers holding paper, and servicers that receive the interest. Threshold is per loan, not per borrower.
Separately, if you file 10 or more information returns across all types in a year, federal rules generally require electronic filing. Most commercial lenders cross that line. Paper filing is the exception, not the BHPH default.
2025 interest: Notice 2025-57 did not require IRS 1098-VLI filing when lenders followed the notice’s borrower-statement path. 2026 interest onward: expect full furnish + e-file — IRS car loan interest reporting.
Set up before filing season
- IRS e-Services account for the responsible official (identity verification via ID.me or the current IRS process).
- IRIS Transmitter Control Code (TCC) application — choose IRIS, not legacy FIRE, unless you still have a narrow FIRE obligation for other forms. Processing can be quick or stretch to weeks in peak season; apply months before March.
- Portal login at iris.irs.gov once the TCC is active.
- A2A only: complete IRIS assurance testing (ATS) before live submissions.
Missing TCC in February is how March 31 becomes a penalty story.
Submit 1098-VLI (portal walkthrough)
The steps below follow Taxpayer Portal entry. If you file through A2A, the same Box 1–7 rules apply in XML — skip to the A2A note at the end of this section.
- Sign in to the IRIS Taxpayer Portal and start a Form 1098-VLI return for the correct tax year.
- One submission = one loan. Enter payer and borrower TINs, names, addresses, Box 1 interest received, vehicle fields (including 17-character VIN), principal and dates, and Boxes 6–7 where required — line-by-line guide.
- Format discipline: plain decimal dollars (
1825.50, not$1,825.50); dates per the form screens; VIN uppercase, no spaces. - Submit and fix field-level errors the portal returns before you move on to the next loan.
- Watch Submission History until status is Accepted (or resolve Accepted with Errors / Partially Accepted / Rejected — see below).
- Furnish Copy B to borrowers by January 31. IRIS does not mail borrower copies for you.
For A2A, the same field rules apply in XML; validate against the IRS schema and XSD before production. Corrections use the IRIS correction workflow and the Unique Record ID from the accepted original.
Errors lenders see repeatedly
- Name/TIN mismatch — SSA/IRS name control rules; fix at source or file corrected returns after W-9 refresh.
- Bad VIN — not 17 valid characters; transpositions from the deal jacket.
- Amount/date format — commas, currency symbols, or wrong date pattern.
- Missing filer contact — payer phone or responsible party fields blank → Accepted with Errors on some transmissions.
- Wrong system for corrections — returns originally filed in FIRE stay in FIRE for corrections; IRIS cannot edit FIRE history (and vice versa during migration).
Treat Accepted with Errors as “filed but fix soon” — CP2100-style follow-ups can still arrive.
Reading status after submission
Typical IRIS transmission states:
| Status | Meaning |
|---|---|
| Accepted | IRS took the filing; keep confirmation and record IDs. |
| Accepted with Errors | Processed with record issues (often TIN); correct via official correction. |
| Partially Accepted | Some returns in, some out — fix and resubmit rejected records as new originals. |
| Rejected | Whole transmission failed (schema/auth); fix and submit a new original. |
If status stalls, check IRS IRIS / e-file provider alerts for platform delays.
IRIS direct vs filing vendor
| IRIS direct | Third-party / platform | |
|---|---|---|
| Cost | No IRS portal fee | Per-form or subscription |
| Work | You own portal entry or A2A/TCC setup | Vendor maps your loan extract |
| Errors | Raw IRS messages | Often clearer UX + mail fulfillment |
| Borrower copies | You furnish | Many vendors bundle mail/portal |
Small SPVL counts: IRIS portal entry is workable. Large or multi-form shops: vendor time savings often beat per-form fees — sign up for 1098-VLI filing.
Start early checklist
- TCC + e-Services done before December.
- Loan export = calendar-year interest received on SPVLs only.
- TIN/VIN/assembly/original-use fields validated in November.
- Test a portal or A2A submission in January; borrower copies out by January 31; IRS acceptance before March 31.
Educational information only, not legal or tax advice. Confirm current IRIS publications, XSD/API guides, and Form 1098-VLI instructions for your filing year.
