E-filing is the fastest and most common way to file federal and state tax returns in the United States. Compared to mailing a paper return, filing online usually means quicker processing, fewer calculation errors, and faster refunds when you choose direct deposit.

Step 1: Gather Your Tax Documents

Before you begin, make sure you have all the information you'll need.

  • Income documents: Collect every tax form that reports your income, including Form W-2, Forms 1099 (such as 1099-NEC, 1099-MISC, 1099-INT, 1099-DIV, and 1099-K), and any brokerage statements.
  • Personal information: Have the Social Security numbers (SSNs) or Individual Taxpayer Identification Numbers (ITINs) for yourself, your spouse (if filing jointly), and any dependents.
  • Last year's tax information: You'll typically need your previous year's Adjusted Gross Income (AGI) or your IRS Identity Protection PIN (IP PIN) to verify your identity when signing your return electronically.

Step 2: Choose an IRS-Approved Filing Method

There are several ways to file your tax return online.

  • IRS Free File: Eligible taxpayers can use free tax software through IRS partners if they meet the annual income requirements.
  • Free File Fillable Forms: If you're comfortable preparing your own return, these electronic versions of IRS forms are available regardless of income.
  • Commercial tax software: Services like TurboTax, H&R Block, and FreeTaxUSA guide you through the filing process with simple questions and automatically complete the required forms.

Step 3: Enter Your Information Carefully

Follow the prompts in your chosen tax software to enter your income, deductions, credits, and other tax information.

Before submitting, use the built-in error checker. Most tax software will flag common issues such as:

  • Missing information
  • Calculation errors
  • Incorrect Social Security numbers
  • Incomplete or inconsistent entries

Step 4: Sign and Submit Your Return

Once you've reviewed everything, it's time to file. You'll generally verify your identity by entering either your previous year's AGI, or your six-digit IRS Identity Protection PIN (IP PIN).

E-Filing vs. Paper Filing

Feature E-Filing Paper Filing
Processing IRS usually acknowledges receipt within 24–48 hours. Processing can take six to eight weeks or longer.
Refund Speed Direct deposit refunds typically issued within 21 days. Paper check refunds generally take several weeks longer.
Accuracy Software checks for common errors before you file. Manual calculations are more likely to cause mistakes.
Security Transmitted through secure, encrypted systems. Paper returns can be delayed, lost, or need manual entry.

Keeping Your Information Secure

Tax returns contain sensitive information. Protect yourself by:

  • Use multi-factor authentication (MFA): Adds an extra layer of security to your login.
  • Choose reputable software: IRS-approved providers use encryption for your data.
  • Consider an IP PIN: Helps prevent someone else from filing a fraudulent return using your SSN.

Final Tips

  • Double-check names, Social Security numbers, and bank account information.
  • Keep copies of your tax return and supporting documents for your records.
  • Choose direct deposit for the fastest refund possible.
  • File early to reduce the risk of identity theft and avoid stress.
