October 2026 Tax Updates: Security, Payroll, and New IRS Tools

The October 2026 tax updates bring several practical changes for Florida small-business owners and individuals. These announcements focus on strengthening data security, transitioning to new filing platforms, and expanding digital access to IRS tools. Staying informed now helps avoid last-minute filing errors and security risks.

This roundup covers the key items from recent IRS news releases and e-news bulletins. We break down what changed, why it matters, and the specific steps you should take to stay compliant and secure.

Protecting Tax Data During Cybersecurity Awareness Month

October is Cybersecurity Awareness Month, and the IRS has released simple steps for taxpayers to secure their financial information against growing online threats. The agency emphasizes that criminals continue to look for new ways to steal taxpayer information and exploit trusted partnerships.

The IRS encourages taxpayers and tax professionals to use strong, unique passwords and turn on multifactor authentication if available. You should also update software and devices regularly, installing updates on computers, phones, tablets, apps, browsers, and security software.

Be cautious of unexpected emails, text messages, social media messages, phone calls, or letters that request personal or financial information or pressure you to act immediately. The IRS normally contacts taxpayers the first time by mail, so verify any urgent requests before sharing data.

• Use a password manager for important accounts.
• Avoid using public Wi-Fi to access financial accounts or IRS online services.
• Encrypt sensitive files and back up important tax records.
• Verify requests to change employee or payment information through a known phone number.

Transition to the Information Returns Intake System (IRIS)

Businesses filing information returns need to be aware of the platform transition from Filing Information Returns Electronically (FIRE) to the Information Returns Intake System (IRIS). The FIRE system will stop accepting returns after Nov. 19, 2026. IRIS will handle those information returns during the 2027 filing season.

IRIS is a portal that allows for the filing of up to 100 returns at a time. Those who need to set up an account with the IRIS system must complete an application for a Transmitter Control Code (TCC). Nov. 1 is the last day to file test information returns through FIRE, and Nov. 9 will be the last day to make changes to the Information Returns Applications for Transmitter Control Codes.

The IRS is hosting two upcoming meetings to help users navigate this change. The first is a Working Group meeting on October 20, 2026, from 1:00 PM to 2:00 PM Eastern Time. This call is intended for software developers, transmitters, and state participants interested in the IRIS system. The purpose is to provide IRIS-related information that can better help users avoid filing errors, address known issues and workarounds, and provide important filing dates and deadlines.

New IRS Mobile App Replaces IRS2Go

The IRS has launched a new free mobile app that allows users to check refund status, view balances, and make payments, replacing the older IRS2Go application. The new IRS mobile app gives clients more ways to securely access IRS tools and account services from their mobile devices.

The free app allows clients to check refund and amended-return status, view available balance information, and make payments and review payment activity. Users can also view select notices and letters, access available tax records and transcripts, and manage certain profile and communication preferences.

The app is available through the Apple App Store and Google Play. Clients should be cautious of look-alike apps, advertisements, and unsolicited messages claiming to provide access to IRS accounts. Individual Online Account, Business Tax Account, and Tax Pro Account continue to be available through IRS.gov.

• Check refund and amended-return status.
• View available balance information.
• Make payments and review payment activity.
• Access an Identity Protection PIN (IP PIN).

National Payroll Week and Security Summit Wrap-Up

Recent payroll professional updates highlight the conclusion of the Summer Security Summit and provide resources for protecting client data year-round. During National Payroll Week, IRS payroll outreach was active on both the national and state levels. IRS stakeholder liaisons participated in payroll conferences, chapter meetings, and statewide events across the country.

The IRS hosted its National Payroll Week webinar, engaging payroll professionals, employers, reporting agents, tax practitioners, and other members of the payroll community. Across these events, the IRS received more than 100 questions and a lot of valuable feedback from participants. The agency is reviewing the questions and feedback and evaluating additional opportunities to provide clarification and education.

The IRS and its Security Summit partners urge tax professionals to stay vigilant against phishing, fake invoices, and W-2 and payroll-related schemes designed to steal employee information, credentials, or money. Businesses, payroll professionals, and human resources offices should remain alert for these threats.

Key October 2026 Tax Updates Summary

These October 2026 tax updates require immediate attention for businesses preparing for the 2027 filing season. The transition to IRIS is the most significant operational change, with hard deadlines in November. Missing these dates could delay your ability to file information returns electronically.

Simultaneously, the security reminders from Cybersecurity Awareness Month are not just for October. Implementing strong password practices and multifactor authentication now protects your business year-round. The new mobile app offers a convenient tool for clients, but verify the source to avoid scams.
