Key Deadlines for 2026 Tax Season

Missing a deadline can mean penalties, interest charges, or a delayed refund. Here are the dates that matter:

Important: A filing extension gives you more time to file, but not more time to pay. If you owe taxes, you still need to pay by April 15 to avoid interest and penalties.

Documents You'll Need

Before you sit down to file, gather everything first. Hunting for documents mid-filing is frustrating and leads to mistakes.

Income documents:

• W-2 from each employer
• 1099-NEC for freelance or contract income
• 1099-INT for bank interest earned
• 1099-DIV for dividend income
• 1099-B for stock or investment sales
• 1099-G for unemployment benefits or state tax refunds
• 1099-R for retirement distributions
• 1099-K for payment app income (Venmo, PayPal, etc.)

Personal info:

• Social Security numbers for yourself, spouse, and dependents
• Last year's tax return (you'll need your prior-year AGI to verify your identity when e-filing)

Deduction and credit documents:

• Form 1098 for mortgage interest paid
• Form 1098-E for student loan interest paid
• Form 1098-T for tuition payments
• Form 1095-A if you had Health Insurance Marketplace coverage
• Receipts for charitable donations
• Records of state and local taxes paid

For your refund:

• Bank account and routing number (for direct deposit -- fastest way to get your money)

Tip: Most of these forms are available online through your employer's payroll portal, your bank, or your brokerage account by early February. Check there before waiting for the mail.

Step-by-Step Filing Guide

Step 1: Choose Your Filing Status

Your filing status affects your tax bracket, standard deduction, and which credits you qualify for. The five options are:

• Single -- unmarried with no dependents
• Married Filing Jointly -- married couples combining income (usually the best deal)
• Married Filing Separately -- married but filing individual returns
• Head of Household -- unmarried with a qualifying dependent
• Qualifying Surviving Spouse -- recently widowed with a dependent child

Not sure which one applies to you? The IRS has an interactive tool, or check out our guide for a detailed breakdown.

Step 2: Gather Your Documents

Use the checklist above to pull everything together. Having it all ready before you start saves time and reduces errors. If a form hasn't arrived by mid-February, contact the issuer directly.

---

Step 3: Pick a Filing Method

This is where people get stuck. There are more free options than you might think. Here's how they compare:

If your AGI is under $84,000, IRS Free File is the easiest no-cost option. The IRS partners with tax software companies to offer guided preparation at no charge.

IRS Free File -- file your federal taxes for free→

IRS Direct File is newer -- it's the IRS's own free filing tool. It's expanding to more states in 2026 and works well for straightforward W-2 returns.

VITA (Volunteer Income Tax Assistance) offers free in-person help at community centers, libraries, and nonprofits. If you'd rather have someone walk you through it face-to-face, this is a great option.

Step 4: Enter Your Income

Report all your income. The IRS already has copies of your W-2s and 1099s, so leaving something out will trigger a notice (and possibly penalties).

Common income sources to report:

• Wages and salary (W-2)
• Freelance and gig income (1099-NEC, 1099-K)
• Interest and dividends (1099-INT, 1099-DIV)
• Investment gains or losses (1099-B)
• Unemployment benefits (1099-G)
• Retirement distributions (1099-R)
• Rental income

If you earned income that didn't come with a form -- like cash payments for side work -- you're still required to report it.

Step 5: Claim Deductions (Standard vs. Itemized)

Deductions lower your taxable income, which means less tax owed. You have two choices:

Standard deduction (2025 tax year):

Itemized deductions make sense if your total deductible expenses exceed the standard deduction. Common itemized deductions include mortgage interest, state and local taxes (SALT, capped at $10,000), medical expenses above 7.5% of AGI, and charitable contributions.

For most people, the standard deduction is the better deal. About 90% of filers take it.

Standard deduction vs. itemizing -- which saves you more?

Step 6: Apply Tax Credits

Tax credits are even more valuable than deductions because they reduce your tax bill dollar-for-dollar. Don't skip this step.

Credits to check:

• Earned Income Tax Credit (EITC) -- up to $7,830 for qualifying low- to moderate-income workers
• Child Tax Credit -- up to $2,000 per qualifying child under 17
• Child and Dependent Care Credit -- for daycare and childcare costs
• American Opportunity Credit -- up to $2,500 per student for college tuition (first 4 years)
• Lifetime Learning Credit -- up to $2,000 for education expenses
• Saver's Credit -- for retirement contributions (lower-income filers)
• Premium Tax Credit -- if you bought health insurance through the Marketplace

Some credits are refundable, meaning you can get money back even if you don't owe taxes. The EITC and a portion of the Child Tax Credit work this way.

Step 7: Review and File

Before you hit submit, double-check these things:

• Names and SSNs match your Social Security cards exactly
• Filing status is correct
• All income is reported (compare against your forms)
• Bank account info is correct for direct deposit
• You've signed the return (or entered your PIN for e-filing)

E-filing is faster, more accurate, and gets your refund sooner than mailing a paper return. The IRS strongly recommends it, and over 90% of returns are filed electronically.

---

Step 8: Track Your Refund

After you file, you'll want to know when your money is coming. The IRS "Where's My Refund?" tool lets you check the status of your return.

Typical refund timelines:

• E-filed with direct deposit: 21 days or less
• E-filed with mailed check: about 4 weeks
• Paper return: 6-8 weeks

You can check your refund status 24 hours after e-filing (or 4 weeks after mailing a paper return).

Free Ways to File Your Taxes

Let's break down the free options in more detail, because nobody should pay to file a simple return.

The bottom line: If you have a W-2 job and take the standard deduction, you can almost certainly file for free. Start with IRS Free File or Direct File.

Common Tax Filing Mistakes

These are the errors the IRS sees most often. Each one can delay your refund or trigger a notice.

1. Wrong Social Security number A single transposed digit will cause the IRS to reject your return. Triple-check every SSN against the actual Social Security card.

2. Math errors Even with software doing the calculations, manual overrides or typos in income amounts cause problems. Let the software handle the math.

3. Missing income Forgot about that freelance gig? The IRS didn't. They receive copies of every W-2 and 1099. Report everything, even if the amount seems small.

4. Choosing the wrong filing status Filing as "Single" when you qualify for "Head of Household" means a smaller standard deduction and higher tax. Make sure you're using the status that benefits you most.

5. Forgetting to sign An unsigned return is treated as if it was never filed. For e-filing, this means entering your prior-year AGI or IP PIN. For paper returns, physically sign and date the form.

Bonus mistake: Not filing at all because you think you don't earn enough. Even if you're not required to file, you should file if you had taxes withheld from your paycheck -- otherwise you're leaving your refund on the table.

What If You Can't File on Time?

Life happens. If you need more time, file Form 4868 by April 15 for an automatic six-month extension. This pushes your filing deadline to October 15, 2026.

You can file the extension electronically through any tax software, or through the IRS Free File system. It takes about five minutes.

But remember -- an extension to file is not an extension to pay. Estimate what you owe and send a payment with your extension to avoid interest and the failure-to-pay penalty (0.5% per month on unpaid tax).

FAQ

Q: Do I have to file a federal tax return?

It depends on your income, filing status, and age. For 2025, single filers under 65 generally must file if their gross income exceeds $15,000 (the standard deduction amount). But even if you're below that threshold, file anyway if you had taxes withheld -- you'll likely get a refund.

Q: How long does it take to get my refund?

Most e-filed returns with direct deposit are processed within 21 days. Paper returns take 6-8 weeks. Returns claiming the EITC or Additional Child Tax Credit may take until mid-March due to the PATH Act, which requires the IRS to hold those refunds.

Q: What if I made a mistake on my return after filing?

File an amended return using Form 1040-X. You can do this electronically through most tax software. You have three years from the original filing date (or two years from when you paid the tax, whichever is later) to file an amendment.

Q: I owe taxes but can't afford to pay. What do I do?

File your return on time anyway -- the failure-to-file penalty (5% per month) is much steeper than the failure-to-pay penalty (0.5% per month). Then apply for an IRS payment plan. Short-term plans (120 days or less) have no setup fee, and long-term installment agreements start at $31 if you pay by direct debit.

Q: I'm a freelancer. Is the filing process different?

You'll report your self-employment income on Schedule C and pay self-employment tax (Social Security and Medicare) on Schedule SE. You may also need to make quarterly estimated tax payments throughout the year. The filing deadline is the same -- April 15.
