Filing your federal tax return to the Internal Revenue Service (IRS) starts with having the right forms in hand. Whether you choose to e-file or submit a paper return, being well-prepared is essential to submitting your tax return on time and without mistakes.
This guide will help you find the IRS forms you need, submit them securely, and avoid common tax filing errors.
Key Takeaways
- All federal tax forms are available for free at IRS.gov.
- The right tax software can help you identify and complete the right forms for your situation.
- E-filing is faster and more secure than mailing a paper return.
- If you’re missing a form, check your IRS transcript or file a substitute form to avoid delays.
How to Find Tax Forms on the IRS Website
The IRS makes all current tax forms available for free on IRS.gov. To find a form, you can:
- Visit the “Find forms & instructions” section and search by form number or name
- Use the site’s search bar to locate a specific form quickly
If you’re using tax software, you don’t need to search for forms manually. These programs include the necessary forms and guide you through questions about your income, deductions, and other details to complete your return accurately.
Important
Tax Day usually falls on April 15, unless it lands on a weekend or holiday. Federal tax returns for 2024 are due on Tuesday, April 15, 2025.
Common Forms and Schedules You Might Need
Most taxpayers use Form 1040. Seniors 65 and up can use Form 1040-SR. Depending on your tax situation, you may also need additional schedules. Some of the most common ones include:
- Schedule A for itemizing deductions
- Schedule B for interests and dividends
- Schedule C for freelance or self-employed income
- Schedule D for capital gains and losses
- Schedule 8812 for the Child Tax Credit
The IRS website offers a complete list of schedules and instructions for each.
Prepare to File
Filing your taxes on time and accurately requires preparation. Here are the steps you’ll need to take.
- Track your tax forms: Keep an eye on any investment or side income forms (such as 1099s). Set reminders to download them and upload them to your tax software.
- Organize your documents: Store all your tax forms, receipts, and prior-year returns in a secure folder, whether digital or physical. Use a checklist based on last year’s return to make sure you don’t forget anything.
- Use secure systems: Electronic filing or “e-filing” is safe through trusted tax software or the IRS website. Use a secure Wi-Fi connection and up-to-date antivirus software, and avoid filing on public networks or computers.
- Know your deadlines: The IRS began accepting 2024 returns on January 27, 2025. Taxes are due by April 15. You can file for an extension, but payment is still due by the deadline to avoid penalties.
Filing Options: Online or By Mail
You can file your federal tax return either electronically or by mailing a paper form.
E-filing is typically faster and includes automatic error checks. The IRS also partners with tax software providers through Free File to offer no-cost e-filing. To be eligible, your Adjusted Gross Income (AGI) must have been below $84,000 in 2024.
If you prefer to mail your return, you can download fill-able PDFs from the IRS website, enter your information, print the forms, and send them by mail. Paper returns can take longer to process, but some filers prefer this method for privacy reasons or because of limited internet access.
Advisor Insight
“If you use a paid preparer to file your tax returns, make sure that they have you sign an e-file signature authorization, such as Form 8879, before they electronically file your return,” cautioned Logan Allec, a CPA and owner of tax relief company Choice Tax Relief. “Also make sure that the amounts on lines 1-5 of this form match the information on your Form 1040.”
What to Do If You’re Missing a Form
If you haven’t received a form, follow these steps:
- Check your email and financial accounts: Many issuers send forms electronically instead of mailing them.
- Review your IRS transcript: Log into your IRS Individual Online Account and check for a Wage and Income Transcript, which shows forms already sent to the IRS by employers or banks. Keep in mind that it may be incomplete early in the season.
- Use a substitute form: If you are missing a W-2 or 1099-R and cannot get a corrected version before the deadline, the IRS allows you to use Form 4852 as a substitute to report your income.
“Round up rather than down when estimating income. The IRS penalizes under-reporting, not overstatement made in good faith,” explained Chad D. Cummings, CPA, Esq., Attorney and CPA at The Law Office of Chad D. Cummings.
Reminder
If you are close to the deadline, file an extension. Just remember, an extension gives you more time to file, not more time to pay. Estimate what you owe and pay by Tax Day.
Cummings also recommends, “Add a memo to your return describing the reconstruction method used. This establishes a paper trail and gives you audit protection. You may amend later with the actual form if received post-deadline, but you will avoid late filing penalties and interest accrual.”
The Bottom Line
Finding and filing your federal tax forms doesn’t have to be stressful. With the right preparation, you can find the tax forms you need, choose the best way to file, and submit your return accurately and on time.
Whether you are e-filing with tax software or mailing paper forms, staying organized and using tools like IRS.gov or your IRS transcript can make the process easier. If a form is missing, take action early and consider options like filing an extension or substitute form to stay on track. Just be sure to estimate and pay any taxes owed by Tax Day to avoid penalties.
