S Corporations & Partnerships can now prepare, e-file, and deliver Schedule K-1s easily with TaxZerone — All in One Place
SAN JOSE, CA, UNITED STATES, February 18, 2026 /EINPresswire.com/ — With the federal business income tax deadline fast approaching, TaxZerone, an IRS-authorized e-file provider, is urging U.S. S-corporations and partnerships to complete their business income tax filings—Form 1120-S and Form 1065—for the 2025 tax year by Monday, March 16, 2026, as the standard March 15 deadline falls on a Sunday. For business owners, accountants, and tax professionals managing multi-owner entities, this deadline carries serious consequences for those who miss it.
For millions of S-corps and partnerships across the country, tax season brings complexity — from generating K-1s for each shareholder or partner, to ensure that every required schedule is complete and accurate. TaxZerone was built specifically to take the guesswork out of this process, giving business owners and their accountants a streamlined, reliable path to compliance.
Business Tax Forms Due by Monday, March 16, 2026
S-corporations and partnerships must file the following federal returns on or before the IRS deadline:
☑️ Form 1120 S: U.S. Income Tax Return for an S-Corporation, including Schedule K-1 for each shareholder reflecting their share of income, deductions, and credits.
☑️ Form 1065: U.S. Return of Partnership Income, including Schedule K-1 for each partner reflecting their distributive share of partnership items.
“S corps and partnerships face unique filing challenges that many businesses don’t,” said a TaxZerone spokesperson. “Preparing accurate K-1s for each shareholder or partner, completing all required schedules, and filing compliant returns—all under deadline pressure—is exactly the kind of challenge TaxZerone was created to solve.”
