Tax Season 2025 Start Date and Filing Deadline Explained

February 10, 2026

Tax season 2025 start date and IRS filing deadline explained

Every year, taxpayers ask the same questions as January approaches. When does tax season start in 2025? When do tax returns come in 2025? Can you file taxes on April 15? These questions matter because the answers determine when you can file, when you must file, and when you can expect a refund.

For the 2025 tax year, understanding the official IRS timeline helps individuals and small business owners avoid penalties, reduce stress, and plan their cash flow more effectively. Tax season dates are set by the Internal Revenue Service, and while the process may feel familiar, the details matter every year.

This guide explains when tax season starts for 2025 returns, how filing deadlines work, whether April 15 is still a valid filing date, and when taxpayers typically receive refunds.

When Does Tax Season Start in 2025

Tax season always begins in the calendar year following the tax year being filed. This means that for income earned during 2025, taxpayers file their federal income tax returns in 2026.

The IRS officially opens the filing season when it begins accepting and processing federal income tax returns. For the 2025 tax year, the IRS began accepting returns in late January 2026. This opening date marks the official start of tax season.

Before this date, taxpayers can prepare returns, gather documents, and work with tax professionals, but the IRS does not process submitted returns until the filing season officially opens. Many tax software providers allow returns to be prepared in advance, but the IRS only acknowledges receipt once tax season begins.

The official start of tax season matters because it triggers refund processing timelines and determines when the IRS systems begin validating returns.

Can You File Before Tax Season Starts

Taxpayers cannot officially file federal income tax returns before the IRS opens the filing season. While preparation can begin earlier, the IRS does not accept or process returns until the official start date.

Some taxpayers confuse preparation with filing. You may complete your return early, but it will not move into processing until the IRS begins accepting submissions. This is why refunds do not arrive before tax season officially starts.

Waiting for the IRS opening date ensures that your return is processed correctly and avoids system rejections.

When Is the Tax Filing Deadline for 2025 Returns

The federal income tax filing deadline is usually April 15. For the 2025 tax year, the deadline to file individual income tax returns and pay any taxes owed is April 15, 2026.

This date applies to most taxpayers in the United States. If April 15 falls on a weekend or federal holiday, the IRS may shift the deadline to the next business day, but for the 2025 tax year, April 15 remains the filing deadline.

The deadline applies whether you owe taxes or are expecting a refund. Filing by the deadline protects you from late filing penalties and interest.

Can You File Taxes on April 15

Yes, you can file taxes on April 15. April 15 is both the final deadline and a valid filing date.

Taxpayers who file electronically can submit returns up until 11:59 p.m. local time on April 15. Returns filed by mail are considered timely if they are properly addressed and postmarked on or before April 15.

Filing on April 15 is common, but waiting until the last day increases the risk of mistakes, delays, or technical issues. Taxpayers who file earlier often receive refunds sooner and have more time to correct errors if needed.

What Happens If You File After April 15

Taxpayers who file after April 15 without an approved extension may face penalties if they owe taxes. The IRS charges penalties for late filing and interest on unpaid balances.

Taxpayers who need more time can request an automatic six month extension by filing Form 4868 on or before April 15. An extension allows more time to file paperwork, but it does not extend the deadline to pay taxes owed.

Any estimated tax liability must still be paid by April 15 to avoid penalties and interest. Extensions only delay filing, not payment.

When Do Tax Returns Come in 2025

Many taxpayers use the phrase when do tax returns come to ask when refunds are issued. Refund timing depends on when the IRS accepts your return and how it is filed.

Most taxpayers who file electronically and choose direct deposit receive refunds within approximately twenty one days after the IRS accepts the return. Paper filed returns typically take longer to process and receive refunds.

Refund timing varies based on filing volume, return accuracy, and whether the IRS needs additional review. Returns claiming certain credits or adjustments may experience longer processing times.

The IRS provides a refund tracking tool that updates status once a return is accepted. This tool is the most accurate way to monitor refund progress.

Why Refunds Can Take Longer

Refunds may take longer for several reasons. Filing by paper slows processing. Errors or missing information may require manual review. Returns claiming certain credits or deductions may trigger additional verification.

The IRS processes millions of returns each season, and timing depends on system volume. Filing early and electronically with direct deposit remains the fastest way to receive a refund.

What Documents You Need Before Filing

Before filing your 2025 tax return, you should gather all required documents. These include W two forms from employers, 1099 forms for contract or freelance income, and records of interest, dividends, or business income.

Most employers must provide W two forms by January 31 following the end of the tax year. Having all documents ready before filing helps reduce errors and delays.

Accurate records also support deductions and credits claimed on the return.

How Extensions Affect Refunds

Taxpayers expecting a refund may still file an extension, but doing so delays the refund. The IRS does not issue refunds until a completed return is filed.

If you are owed a refund, filing earlier typically benefits you. Extensions mainly help taxpayers who need additional time to organize records or resolve complex issues.

What Small Business Owners Should Know

Small business owners often have more complex filing requirements. Business income, estimated taxes, and additional forms can affect timing and accuracy.

Preparing early helps business owners coordinate with tax professionals, review profit and loss statements, and confirm deductible expenses. Clean bookkeeping supports accurate filing and reduces the risk of IRS inquiries.

Planning ahead also helps manage cash flow if taxes are owed.

Tax Season Planning for 2025

Tax season for 2025 returns begins in late January 2026 and ends on April 15, 2026. Filing early, staying organized, and understanding deadlines help taxpayers avoid penalties and receive refunds faster.

The IRS sets these dates each year, and while the process is familiar, the details matter. Knowing when tax season starts, when you can file, and when refunds arrive gives you more control over your financial planning.

Tax season for the 2025 tax year officially begins when the IRS opens filing in late January 2026. Taxpayers can file returns starting on that date. The deadline to file and pay taxes owed is April 15, 2026. Yes, you can file taxes on April 15 as long as the return is submitted or postmarked by that date.

Most refunds arrive within several weeks after the IRS accepts a return, especially for electronic filers using direct deposit. Filing early, preparing documents in advance, and understanding deadlines help reduce stress and improve outcomes during tax season.
