How to File Taxes Online Safely

Filing taxes online can be faster, easier, and more convenient than mailing a paper return. But it also means you are entering sensitive information, including your Social Security number, income, bank account details, and identity verification information, into an online system.

In this guide, you’ll learn how to file taxes online safely, choose trusted filing options, protect your personal information, and avoid common tax scams.

• If you qualify for IRS Free File → start from IRS.gov, not a random search result.
• If you use tax software → choose a trusted provider and confirm the website address before entering information.

Step 1: Choose a Trusted Online Filing Option

The first safety decision is where you file. A legitimate filing option should clearly explain pricing, security, filing support, and how your information will be used.

Common online filing choices include:

Filing Option	Best For
IRS Free File	Eligible taxpayers who want free guided federal filing
Free Fillable Forms	People comfortable preparing their own federal return
Commercial tax software	Simple to moderately complex returns
Tax professional with secure portal	More complex situations or people who want guidance

IRS Free File lets eligible taxpayers prepare and e-file their federal return for free using guided tax software through IRS partner sites. The IRS says taxpayers should begin at IRS.gov/freefile to access Free File options.

What to do:
Go directly to the official website of the IRS, tax software provider, or tax professional. Avoid clicking sponsored links, email links, text links, or social media ads when entering tax information.

Step 2: Confirm You’re on the Real Website

Tax scammers create fake websites that look like tax software companies, IRS pages, or refund tools. Some scams use urgent language to push you into entering personal information quickly.

Before logging in or creating an account, check:

• Website address is spelled correctly
• The site uses https
• You reached it by typing the address directly
• The page does not ask for unnecessary information upfront
• The company name matches the official tax provider
• The page does not promise unrealistic refunds
• The site does not pressure you with threats or countdowns

The IRS warns taxpayers to watch for phishing and smishing scams, including emails, texts, direct messages, and QR codes that lead to fake IRS websites. (irs.gov)

What to do:
If a link came from a message, do not use it. Open a new browser window and go directly to the official site.

Smile Money Tip:
Urgency is a scammer’s favorite tool. If a message makes you feel rushed, threatened, or excited about a surprise refund, slow down before you click.

Step 3: Protect Your Tax Filing Account

Your tax software account may contain enough information for identity theft. Treat it like a financial account.

Use:

• A strong, unique password
• Multi-factor authentication
• A personal device you trust
• A secure internet connection
• A password manager, if helpful
• Updated browser and device software

Avoid:

• Filing on public Wi-Fi
• Saving passwords in shared browsers
• Using the same password as email or banking
• Filing on a public computer
• Sharing login credentials with others
• Leaving your tax account open on a shared device

What to do:
Set up multi-factor authentication before entering tax documents. If someone gets your password, the second step can help protect your account.

Step 4: Gather Documents Before You Log In

Online filing is safer and smoother when you are prepared. If you keep logging in and out, searching email, downloading forms, and switching devices, it is easier to make mistakes.

Gather:

• W-2s
• 1099s
• 1098 forms
• Prior-year return
• Social Security numbers or ITINs
• Dependent information
• Bank routing and account numbers
• IRS Identity Protection PIN, if issued
• Estimated tax payment records
• Deduction and credit records

The IRS recommends gathering tax records before filing to help file a complete and accurate return and avoid refund delays. (irs.gov)

What to do:
Create one secure tax folder before starting your return. If digital, use clear file names and secure storage.

Step 5: Use an IRS Identity Protection PIN

An IRS Identity Protection PIN, or IP PIN, is a six-digit number that helps prevent someone else from filing a tax return using your Social Security number or ITIN. The IRS says the IP PIN is known only to you and the IRS and helps verify your identity when you file electronically or by paper. (irs.gov)

Anyone with a Social Security number or ITIN who can verify their identity can request one.

An IP PIN can be especially useful if:

• You were a victim of identity theft
• Your personal information was exposed in a data breach
• You had a suspicious tax filing issue before
• You want extra protection before someone else files in your name

What to do:
If you choose to get an IP PIN, keep it secure. You will need the current year’s PIN when filing.

Step 6: Review Refund and Payment Information Carefully

Bank account errors can delay refunds or send money to the wrong place. Payment errors can also cause missed tax payments.

Before filing, confirm:

• Routing number
• Account number
• Account type
• Refund amount
• Tax payment amount
• Payment date
• State refund or payment details
• Whether fees are being deducted from your refund

The IRS says electronic filing with direct deposit is the fastest way to get a refund, and direct deposit can be used for one, two, or three accounts. (irs.gov)

What to do:
Enter bank information from your bank’s official app, website, check, or account documentation. Do not rely on memory.

Step 7: Watch for Tax Scams Before and After Filing

Tax scams often increase during filing season. Scammers may pretend to be the IRS, a tax software company, a refund processor, or a tax preparer.

Watch for:

• Emails claiming your refund is on hold
• Texts asking you to verify tax information
• QR codes that lead to fake IRS pages
• Calls threatening arrest or legal action
• Social media posts promoting fake credits
• Messages promising huge refunds
• “Ghost preparers” who refuse to sign returns
• Requests for payment by gift card, crypto, or wire transfer

The IRS says taxpayers should not click links or open attachments from unexpected IRS-related messages and should report suspicious IRS-related emails, texts, and messages. (irs.gov)

What to do:
If something feels suspicious, stop. Go directly to IRS.gov or your tax software account instead of responding to the message.

Step 8: Save Your Return and Confirmation Securely

After filing, save your records. Do not leave tax documents scattered in downloads, email attachments, or screenshots.

Save:

• Full copy of your filed return
• E-file acceptance confirmation
• Payment confirmation, if you paid
• Refund tracking details
• W-2s and 1099s
• Deduction and credit records
• IP PIN notice, if applicable
• State return confirmation

IRS Free File provides email confirmation when the IRS accepts your return, and rejected e-filed returns can often be corrected and resubmitted before the deadline. (irs.gov)

What to do:
Store files in a secure folder and back them up. Use a file name like 2025 Federal Tax Return – Filed 2026.

Common Mistakes to Avoid

• Clicking tax filing links from texts or emails
• Filing on public Wi-Fi
• Using weak or repeated passwords
• Ignoring multi-factor authentication
• Entering bank details from memory
• Falling for “surprise refund” messages
• Sharing tax software logins
• Forgetting to save the e-file confirmation
• Using a preparer who does not sign the return
