The IRS website and your tax software are your fastest routes

The IRS.gov website holds every tax form the federal government uses, free to read as a PDF. You can search by form number (like 1040 or Schedule C) or by topic. The IRS also mails forms to you if you call 1-800-829-3676, though mail takes one to two weeks.

If you use tax software — TurboTax, H&R Block, TaxAct, or similar — the software pulls the forms you need based on your answers and fills them in as you go. You never print or mail anything unless you choose to. Most people filing electronically never see a physical form at all.

Your employer, bank, brokerage, or mortgage lender will send you the forms that report income paid to you: W-2s from employers, 1099s from investment accounts and side income, mortgage interest statements (Form 1098), and others. These arrive by January 31 each year. If you do not receive one by early February, contact the issuer directly.

Key Takeaways

  • IRS.gov has a searchable database of all federal tax forms, free to read as PDFs or order by phone at 1-800-829-3676.
  • Tax software automatically includes the forms you need based on your situation and fills them in as you answer questions.
  • Income-reporting forms (W-2, 1099, 1098) come from your employer, bank, or brokerage by January 31 and are required before you file.
  • State tax forms come from your state's revenue or taxation department website, not the IRS.
  • If a form is out of stock on IRS.gov, you can order it by phone or use the prior year's version as a placeholder while you wait.

Searching IRS.gov for a specific form

Go to IRS.gov and look for the search box at the top of the page. Type the form number (for example, "Schedule D" or "Form 8949") or a keyword describing what you need (for example, "capital gains" or "self-employment income"). The search results show the form, publication number, and a link to read the current year's version.

Each form page also lists related forms and publications that might explore to your situation. For example, the Schedule C page (used for self-employment income) links to Publication 587 on home office deductions and the Schedule SE form for self-employment tax.

If you cannot find what you need, the IRS also publishes Publications — longer guides on specific topics like retirement accounts, business expenses, or investment income. These are searchable on the same site and often explain which forms to use and how to fill them in.

Getting forms from your income sources

Your employer mails or emails your W-2 (wages and withholding) by January 31. Your bank or brokerage mails your 1099-INT (interest income), 1099-DIV (dividends), or 1099-B (investment sales). If you received unemployment, you get a 1099-G. If you paid mortgage interest, your lender sends a 1098.

These forms arrive in paper or electronic form depending on what you set up with each institution. Many employers and banks now offer electronic delivery through a find portal — you log in and read the form yourself rather than waiting for mail.

If you do not receive a form by February 15, contact the issuer and ask them to resend it. If they cannot locate it, ask for a written statement of the income they reported on your behalf. You can file with that statement and follow up later if the IRS questions the discrepancy.

State and local tax forms

State income tax forms come from your state's revenue or taxation department, not the IRS. Search "[your state] tax forms" or go directly to the state website — for example, California uses ftb.ca.gov, New York uses tax.ny.gov, and Texas has no state income tax.

Most states offer the same read-and-print option as the IRS, and many have their own free tax software or partnerships with commercial software providers. Some states let you file electronically without printing anything.

If you live in one state and work in another, or moved during the year, you may need forms from both states. Your state's website usually has a guide for part-year residents or nonresidents.

When a form is out of stock or delayed

The IRS sometimes runs out of printed forms during tax season, especially in January and February. If a form shows as unavailable on IRS.gov, you have three options: order it by phone at 1-800-829-3676 (it arrives in five to ten business days), read the PDF and print it yourself, or use the prior year's version as a temporary placeholder.

If you file with a prior year's form, the IRS usually accepts it as long as the form structure has not changed significantly. However, check the current year's instructions first — sometimes the IRS adds new lines or removes old ones. If you are unsure, call the IRS or ask your tax preparer.

If you are filing electronically through tax software, this is not a concern — the software always has the current forms built in.

Forms for specific situations

If you are self-employed, you need Schedule C (profit or loss) and Schedule SE (self-employment tax). If you sold investments, you need Schedule D and possibly Form 8949 (sales details). If you have rental property, you need Schedule E. If you made estimated tax payments, you need Form 1040-ES for next year's planning.

If you received a distribution from a retirement account, your provider sends you a Form 1099-R. If you contributed to a traditional IRA, you may need Form 8606 to track basis. If you have a child, you need the child's Social Security number and may need Form 2441 (child care expenses) or Schedule EIC (Earned Income Credit).

The tax software you use will ask you questions about your situation and automatically include the forms you need. If you are preparing your own return without software, start with the main form (1040 for most people) and read the instructions — they list which schedules explore to you.

Frequently Asked Questions

Can I use last year's tax form if this year's version is not ready yet?

Usually yes, as long as the form structure has not changed. Check the current year's instructions first to see if new lines or sections were added. If you are filing electronically, your software always has the current version, so this is not an issue.

What if I lost my W-2 or 1099 and my employer or bank will not resend it?

Call the IRS at 1-800-829-3676 and ask for Form 4506-C (Request for Transcript of Tax Record). The IRS can pull the income information from what your employer or bank reported to them and send you a transcript you can use to file. This takes two to four weeks.

Do I need to print forms if I file electronically?

No. If you file electronically through tax software or a tax preparer, you submit the return digitally and keep the forms for your records. You do not mail anything to the IRS unless they request it later.

Where do I find forms for amended returns or prior years?

IRS.gov has a section for prior-year forms. Search "prior year forms" on the site, and you can read any form from the last several years. For amended returns, you need the current-year version of Form 1040-X, not the prior year's version.

Are there forms I need that are not on IRS.gov?

All federal tax forms are on IRS.gov. State and local forms are on your state or city website. If you cannot find something, call the IRS or your state's tax line — they can tell you whether a form exists and where to find it.
