What filing guidance did the IRS issue in 2025 for Schedule A due to new forms?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
The IRS released draft and new 2025 schedules and related guidance showing a notable change: a brand-new draft Schedule 1‑A (Form 1040) — “Additional Deductions” — was published for 2025 to carry four temporary deductions enacted for tax years 2025–2028; the draft will first affect returns filed in the 2026 filing season for the 2025 tax year (draft noted on IRS site and explained by tax firms) [1] [2] [3]. The agency’s main public instruction is to consult the IRS Schedule A and Forms pages for the latest drafts and to attach the appropriate Schedule A forms to their matching returns (Form 1040/Schedule A or Form 1040‑NR Schedule A, and other Schedule A variants like Form 940 and 8804 as applicable) [4] [5] [6] [7].
1. New forms created pressure to issue draft guidance
The “One Big Beautiful Bill” changes prompted the IRS to draft a new Schedule 1‑A to accommodate four new below‑the‑line deductions rather than shoehorning them onto existing paperwork; professional reviewers and software vendors flagged the draft Schedule 1‑A as the vehicle for those additions [3] [2]. The IRS has posted draft forms and repeatedly told taxpayers and preparers to check the IRS forms pages and the schedule‑specific pages for the latest versions and instructions [8] [4].
2. What the IRS actually published (drafts, not final rules)
Available IRS materials in the search results include draft PDFs of 2025 forms and instructions — notably a draft Schedule A (Form 1040) and a draft Schedule 1‑A — and guidance pages that point users to where updated instructions will appear [4] [1] [8]. Independent tax‑product firms and tax‑professional commentary likewise note that the IRS released drafts and is soliciting practitioner review; industry coverage emphasizes the draft status and that final forms will govern filing when returns are filed in 2026 for tax year 2025 [2] [3].
3. Practical filing guidance the IRS released or signaled
The core IRS filing instruction visible in these materials is procedural: attach the correct Schedule A variant or other schedule to the tax return you file (for example, Schedule A to Form 940, Schedule A or Schedule A (1040‑NR) to their respective returns) and go to the IRS Schedule A or form pages for the latest information and instructions [6] [4] [5]. The IRS forms index continues to be the central portal for updated drafts and final forms [8].
4. What the new Schedule 1‑A covers and why it matters
Technical reviews and tax‑software explainers show Schedule 1‑A organizes four new deductions (qualified tips, overtime compensation adjustments, certain car loan interest, and an enhanced senior deduction) and contains MAGI‑based phase‑outs and calculation parts — meaning the new schedule changes how “below‑the‑line” deductions are computed and could affect taxable income calculations [3] [2]. Those sources stress the deductions are temporary for 2025–2028 and that the draft form includes multiple parts to compute MAGI and phaseouts [2] [3].
5. Industry response and caveats from tax preparers and software vendors
Tax vendors and technical blogs emphasize that only draft forms were published at the time of reporting and that software and payroll coding (for example W‑2 box/code changes) may lag — the payroll/W‑2 coding issue is highlighted as a transitional problem for claiming some deductions tied to wage reporting [9] [2]. Tax‑professional commentary details the mechanics of the draft and invites practitioners to submit comments to the IRS’s draft form comment channels [3].
6. Limits of the available reporting and what’s not found
Available sources do not mention a finalized IRS revenue procedure or a single consolidated taxpayer bulletin that replaces existing Schedule A instructions; they show draft forms and page guidance telling users to “go to” the IRS pages for updates [4] [8]. The materials in the search results do not provide a single, finalized instruction memorandum telling filers exactly how to claim the new deductions on submitted 2025 returns — they present drafts and industry analyses instead [2] [3].
7. What taxpayers should do now
Tax preparers and taxpayers should monitor the IRS forms and instructions pages, review the draft Schedule 1‑A and related draft instructions to anticipate the mechanics and MAGI phaseouts, and be prepared for payroll/W‑2 transitional issues that advisors warned could delay standardized reporting until 2026 [8] [2] [9]. For returns that require other Schedule A variants (Form 940, 8804, 1040‑NR), the IRS’s form pages and the specific schedule PDFs state to attach the appropriate Schedule A when filing [6] [7] [5].
Limitations: this summary relies on draft IRS forms and third‑party technical reviews and tax‑product explainers in the search results; available sources do not include a final IRS filing‑season directive or consolidated final instructions for taxpayers filing 2025 returns [1] [2] [3].
