"Flash"-Connecticut Tax Return Delays: What Businesses and Individuals Need to Know

The Connecticut Department of Revenue Services (DRS) recently announced a significant delay in the release of tax forms for S corporations (CT-1120SI) and partnerships (CT-1065), creating a ripple effect for businesses and individuals alike. This unexpected setback stems from the DRS providing necessary tax specifications to software vendors later than usual—on February 7, 2025—which has caused major disruptions in the filing process.

For business owners and taxpayers affected by this delay, here’s what you need to know and how to prepare.

Why Are CT Tax Filings Delayed?

Each year, tax software companies integrate updates based on state and federal tax requirements. However, with the Connecticut DRS supplying its required specifications nearly a month late, software vendors have not yet released Connecticut tax forms, preventing accountants and taxpayers from filing returns—or even generating preliminary drafts.

What This Means for Your Business and Personal Tax Returns

If you operate a partnership or S corporation in Connecticut, these delays directly impact your ability to file your business return. The key consequences include:

  • No Preliminary Drafts Available – Software vendors have restricted access to Connecticut forms, meaning business owners and tax preparers cannot even review preliminary versions of the returns.

  • Delays in Issuing K-1s – Without a completed business return, Schedule K-1s (used for reporting pass-through income) cannot be generated. This directly affects personal tax filings for business owners.

  • Potential Need for Personal Tax Extensions – If your individual tax return depends on receiving a K-1, you may need to file an extension to avoid filing an incomplete return.

How to Navigate the Delay: Filing Extensions & Payment Deadlines

Given the uncertainty around when Connecticut forms will be available, filing extensions is the best course of action for both business and personal tax returns.

Key Extension Recommendations:

S Corporations & Partnerships (Forms 1065 & 1120S) – We strongly advise filing federal and Connecticut business tax extensions.
Individual Taxpayers (1040s) – If your return depends on a K-1, filing a Connecticut and federal extension is also recommended.
Deadlines Still Matter – An extension only delays the filing deadline—it does NOT extend the time to pay. Taxes owed must be paid by April 15, 2025 to avoid penalties and interest.

Penalty Relief for Connecticut Business Filers

The Connecticut DRS has introduced a penalty relief initiative for taxpayers affected by this delay. To qualify:

  • File an extension for CT-1065/CT-1120SI by April 15, 2025

  • Pay any taxes owed by April 15, 2025

By doing so, Connecticut will waive penalties and interest that would have otherwise accrued between March 15 and April 15, 2025. However, businesses failing to meet these requirements will not be eligible for this relief.

What Happens If Connecticut Software Becomes Available Before the Deadline?

We are closely monitoring the situation, and if tax software companies release Connecticut forms before any extension deadlines, we will process returns as quickly as possible to minimize delays. However, given the uncertainty, we strongly encourage proactive extension filings to avoid last-minute complications.
