The Marketplace Identifier on Form 1095-A sits on Line 1, at the top of Part I. It’s a short code identifying the state exchange that administered your health plan, and you’ll copy it directly onto Form 8962 when you file your federal return to reconcile your Premium Tax Credit.
Where the Identifier Sits on the Form
Part I of Form 1095-A carries both of the identifying numbers the IRS wants from you. Line 1 is the Marketplace Identifier. Line 2, right below it, is your Policy Number, which the Marketplace assigned to your specific coverage. The two are not interchangeable, and Form 8962 asks for each one separately, so copy from the correct line.
Lines 3 through 15 of Part I round out the recipient information: your name and the names of covered individuals, Social Security numbers, the coverage start and end dates, and details about the insurance company that issued the plan. Read through this section before you file. If a name, SSN, or coverage date is wrong, the IRS may flag a mismatch when it cross-references your return against what the Marketplace reported.
Getting Your 1095-A If You Don’t Have It Yet
Your Marketplace is responsible for sending Form 1095-A, not the IRS. The official furnish date is January 31 following the coverage year, so for the 2025 plan year, Marketplaces must send the form by January 31, 2026.
The fastest route is your Marketplace account. If you enrolled through the federal exchange at HealthCare.gov, an electronic copy usually appears in your account in mid-January, often before the mailed paper copy arrives. State-based exchanges post the form through their own portals. Log in with the account you used to enroll and look for a tax forms or tax documents section.
If the form isn’t there, or you’ve lost access to your account, call the Marketplace. The federal Marketplace Call Center is 1-800-318-2596 (TTY: 1-855-889-4325). State exchange enrollees should call their state’s customer service line. A representative can confirm whether the form was mailed, resend it, or help you reach it online.
What to Do With the Identifier on Form 8962
Form 8962 reconciles the Advance Premium Tax Credit (APTC) paid toward your coverage during the year against the actual credit your final income supports. If any APTC was paid on your behalf, you must file Form 8962 with your return, even if you wouldn’t otherwise be required to file.
Copy the Marketplace Identifier from Line 1 of your 1095-A and the Policy Number from Line 2 onto the matching entries on Form 8962. Then move to Part III of the 1095-A, which breaks your coverage down month by month in three columns, and carry those monthly figures over to the corresponding lines on Form 8962.
- Column A, Monthly Enrollment Premiums: the full premium for your plan each month, before any credit was applied.
- Column B, Monthly SLCSP Premium: the cost of the second lowest cost Silver plan available to you, which the IRS uses as the benchmark for calculating your credit regardless of the plan you actually chose.
- Column C, Monthly Advance Payment of Premium Tax Credit: the amount paid directly to your insurer each month to lower what you owed.
Column B is the one that trips people up. If it’s blank or looks wrong, use the Health Coverage Tax Tool at HealthCare.gov/tax-tool/ to look up the correct SLCSP premium for your location and household. Don’t guess, and don’t leave it empty on Form 8962; the SLCSP figure directly controls the size of the credit you’re entitled to.
Once the numbers are entered, Form 8962 compares what the Marketplace estimated you’d qualify for (based on the income you projected at enrollment) against what you actually qualify for now that the year is closed. If your real income came in below your estimate, you receive an additional refundable credit. If it came in higher, you repay some or all of the excess APTC. The federal filing deadline for the 2025 tax year is April 15, 2026.
If the Premium Numbers Don’t Look Right
Before deciding the form is wrong, check a few explanations. Column A may show only the portion of your premium covering essential health benefits, which can be lower than the bill you remember if your plan bundled extras like adult dental or vision. If anyone on the plan started or ended coverage mid-month, that month will show a prorated amount. And if your household included a standalone dental plan with a child under 18, the form may fold in a share of the pediatric dental premium, pushing Column A higher than you’d expect.
If none of that explains the discrepancy, call the Marketplace and request a corrected 1095-A. Federal exchange enrollees use 1-800-318-2596. The Marketplace will review the account and issue a corrected form if the numbers were wrong. Don’t file your return with figures you know are inaccurate. Wait for the correction, even if that means filing closer to the deadline or asking for an extension.
If Your Plan Covered Someone Outside Your Tax Household
One situation changes how you use the 1095-A numbers. If your plan covered a person who isn’t on your tax return, such as an adult child who files independently or a former spouse after a mid-year divorce, you split the Column A, B, and C amounts between tax households through Part IV of Form 8962. You and the other filer can agree on any percentage split from 0% to 100%, as long as the shares add to 100% and you apply the same percentage across all three columns in a given month. If you can’t agree, the IRS defaults to a proportional split based on the number of people from each tax family who were enrolled. For a divorce finalized during the year, you allocate only the months you were married, and each former spouse reports their share on their own Form 8962. The Form 8962 instructions walk through the specific scenarios in detail.
If you already filed a return without Form 8962 attached, the IRS expects an amended return. Use your 1095-A to complete Form 8962 and attach it to the amendment. If you don’t have the 1095-A in hand, request a copy from the federal Marketplace at 1-800-318-2596 or from your state exchange before amending.
