Fill Schedule A (Form 1040) online — free
Schedule A (Form 1040) is the IRS schedule you attach to Form 1040 or 1040-SR to figure your itemized deductions — medical and dental expenses, state and local taxes, mortgage interest, gifts to charity, and more. AttachKit lets you open the official blank PDF and fill it in your browser, with nothing ever uploaded. From your saved profile it drafts the common fields at the top — the name(s) shown on Form 1040 and your Social Security number — so you can focus on the deduction lines yourself.
Who needs it: People who itemize deductions instead of taking the standard deduction use Schedule A. In most cases your federal income tax is lower if you take the larger of your itemized deductions or your standard deduction.

Schedule A (Form 1040) questions, answered
General information, not legal or tax advice
This page is general information about a commonly-used tax form. Tax law is complex and fact-specific — for advice on your return, consult a CPA, enrolled agent, or tax attorney. AttachKit fills the PDF; the IRS holds you responsible for what's on it.
- Does AttachKit fill in my deduction amounts automatically?
- No. AttachKit only drafts common profile fields like your name and SSN. You enter and review every deduction line — medical, taxes, interest, charity — yourself.
- Is my tax information uploaded anywhere?
- No. Filling happens entirely in your browser and the PDF stays on your device. Nothing is sent to a server.
- Where do I get the official Schedule A PDF?
- Download the current blank form from the IRS at irs.gov, then drop it into the AttachKit tool to fill it on your device.
- Can AttachKit file Schedule A with the IRS?
- No. AttachKit does not submit, e-file, or calculate your taxes, and it is not tax advice. You file Schedule A with your Form 1040.
