What You Need to Know About 2026 Tax Filing Changes

With each new year comes a set of IRS and Treasury rule changes—some small, some significant—that can affect how and when you file your tax returns. While these updates may not have received much publicity, a few could materially impact both individual and business taxpayers.

Proof of Timely Filing: New Postal Rules

The Postal Service changed how it postmarks mail starting in December 2025. Mail is now postmarked based on when it’s processed at a regional sorting facility, not when it’s placed in a collection box. This means dropping your envelope at the post office near midnight on April 15 no longer guarantees a timely postmark.

To avoid late-filing penalties, taxpayers should:

· File electronically — the fastest method, providing immediate confirmation from the IRS.

· Request proof of mailing — options include a certificate of mailing, certified mail (with return receipt), or Priority Mail with tracking.

· Use an approved private delivery service — the IRS maintains a current list of approved carriers here.

Refunds Go Digital

Under a March 2025 Executive Order, Treasury is transitioning all payments—including tax refunds—away from paper checks to secure electronic transfers. Beginning with 2025 tax refunds, most individuals will receive funds by direct deposit or potentially via digital wallets. Paper checks are being phased out for individual taxpayers, though they continue for trusts, estates, and corporations.

If you haven’t done so already, provide your bank routing and account information when filing to avoid delays. And because Treasury’s implementation timeline continues to evolve, check with your tax preparer to ensure compliance.

Paying Taxes: Still Multiple Options

While Treasury is evaluating the possibility of phasing out paper checks for taxes due, individuals and trusts may still pay by mail or online. Accepted payment options include:

· Electronic Federal Tax Payment System (EFTPS) — required for large payments.

· IRS Direct Pay — a secure, no-fee online payment tool.

· Credit or debit card payments — available, though subject to processing fees.

Creating an IRS Online Account is also recommended. This provides access to payment history, prior returns, refund status, IP PIN applications, and installment agreement setup.

IRS Direct File: Program Ended

The IRS Direct File pilot, which allowed certain taxpayers to file simple returns directly with the IRS, ended in November 2025. However, several no-cost filing options remain:

· IRS Free File through partner software.

· Volunteer Income Tax Assistance (VITA) and Tax Counseling for the Elderly (TCE) programs.

· IRS Free Fillable Forms for those comfortable preparing returns manually.

Many of the 2026 filing season’s changes aim to modernize submission and payment systems, but they also narrow the margin for error. Plan ahead, confirm mailing and payment methods, and consult your tax professional to ensure a smooth and compliant filing experience.
