What documentation do I need to reconcile APTC for 2025 and where does Marketplace send Form 1095-A?
Executive summary
You must file Form 8962 with your federal tax return to reconcile any advance premium tax credit (APTC) you received for 2025; Form 1095‑A from the Marketplace provides the data you need and is furnished to each tax filer or responsible adult by about mid‑January to February 1 (and mailed no later than mid‑February or January 31 in some notices) so you can complete Form 8962 and reconcile APTC [1] [2] [3]. If you fail to file and reconcile APTC for two consecutive years, Marketplaces may deny APTC for later plan years [4] [5] [6].
1. What “reconciling APTC” means — the core paperwork
Reconciling APTC means reporting the advance payments of the premium tax credit you received during the coverage year on your federal return, computing your actual Premium Tax Credit (PTC) using Form 8962, and attaching Form 8962 to your return; the process compares APTC paid on your behalf to the PTC you’re entitled to based on actual annual income and household size [1] [7] [8]. IRS guidance is explicit: for tax years with any APTC you must file Form 8962 and attach it to your return to reconcile the difference [1].
2. The one form you can’t skip: Form 8962
If you received any APTC in 2025, you are required to complete Form 8962 (Premium Tax Credit) and file it with your federal tax return for that tax year; failing to do so is the filing failure the Marketplace checks when deciding future APTC eligibility [1] [7].
3. Where the Marketplace sends Form 1095‑A and when to expect it
The Marketplace (federally facilitated or state-run) furnishes Form 1095‑A, the Health Insurance Marketplace Statement, to the tax filer or responsible adult who enrolled in coverage; it’s typically available in your Marketplace account from mid‑January to February 1 and mailed by mid‑February or by January 31 depending on Marketplace notices and state practices [2] [3] [9]. The IRS and HealthCare.gov state you must have Form 1095‑A before you file because it contains the monthly premiums, the second‑lowest‑cost Silver plan premium (SLCSP) figures, and the amounts of APTC paid that you use on Form 8962 [10] [2].
4. What’s on Form 1095‑A and why it matters for reconciliation
Form 1095‑A provides recipient and policy information, monthly premium amounts, the SLCSP monthly premium needed to calculate PTC, and the monthly APTC amounts — all the line items required to complete Form 8962 accurately. The Marketplace also files a copy with the IRS, so discrepancies can trigger corrections or require amended returns [11] [10] [9].
5. Deadlines, timing and practical filing tips
HealthReform and HealthCare.gov materials remind taxpayers that you reconcile the APTC for the prior coverage year when you file taxes (e.g., reconcile 2024 APTC by April 2025) and you should wait to file until you have your 1095‑A in hand or downloaded from your account [12] [2]. If you receive a corrected 1095‑A, use the corrected version — sometimes you must amend an already‑filed return if the Marketplace issues a corrected or voided form [2] [10].
6. Enforcement: what happens if you don’t file and reconcile
CMS guidance and Marketplace notices explain that, beginning with plan year 2025 processes and related rulemaking, consumers who fail to file federal returns and reconcile APTC for two consecutive years may be found ineligible for future APTC (a change from the earlier one‑year trigger); CMS paused some automated Failure to File and Reconcile (FTR) operations but the policy is in effect for determining eligibility once implemented [4] [5] [6]. Advocacy and policy groups note the change reduces the chance of losing APTC for a single missed year, but two missed years can still block subsidies until the filer resolves past reconciliations [13].
7. If numbers don’t match or you don’t receive 1095‑A
If you believe your Form 1095‑A is incorrect or you didn’t receive it, the Marketplace call center and your Marketplace account are the first stops; agents advise contacting the Marketplace to request corrections and to download the form from your account [14] [15]. The Marketplace must furnish the form (and may require affirmative consent for electronic delivery), and consumers are urged to keep the 1095‑A with tax records because a copy is also reported to the IRS [16] [10].
