Final Days to File: TaxZerone Reminds S Corporations and Partnerships to Submit Forms 1120-S and 1065 by March 16, 2026

TaxZerone helps businesses prepare, e-file 2025 Form 1120-S & 1065 returns and securely distribute Schedule K-1s — all-in-one platform.

SAN JOSE, CA, UNITED STATES, March 10, 2026 /EINPresswire.com/ -- With the federal filing deadline only days away, TaxZerone, an IRS-authorized e-file provider, is reminding S corporations and partnerships across the United States to submit their 2025 business income tax returns before Monday, March 16, 2026. Because the traditional March 15 deadline falls on a Sunday this year, the Internal Revenue Service (IRS) has moved the filing deadline to the next business day.

For business owners, tax professionals, and accountants managing pass-through entities, missing the deadline can lead to IRS penalties and compliance complications. As the deadline approaches, many businesses are working quickly to complete their returns and generate the required Schedule K-1 forms for shareholders and partners.

TaxZerone provides a streamlined online solution designed specifically to simplify these filings and help businesses meet the deadline without unnecessary complexity.

Business Tax Returns Due March 16, 2026
S corporations and partnerships must submit the following federal returns to the IRS by the March deadline:
✔️ Form 1120-S – U.S. Income Tax Return for an S Corporation, including Schedule K-1 for each shareholder.
✔️ Form 1065 – U.S. Return of Partnership Income, including Schedule K-1 for each partner.

These returns are essential for pass-through entities because they determine the income allocations that shareholders and partners must report on their individual tax returns.

Simplifying Complex Business Filings
Preparing business tax returns often involves multiple supporting forms, financial schedules, and detailed ownership information. In addition, businesses must ensure that each shareholder or partner receives an accurate Schedule K-1.

TaxZerone simplifies this process by providing a guided, cloud-based filing platform that helps businesses prepare their returns efficiently and file them electronically with the IRS.

“Business tax filings for pass-through entities can become complex very quickly,” said a TaxZerone spokesperson. “Our platform is designed to help businesses complete their returns accurately, generate Schedule K-1s automatically, and file with confidence before the deadline.”

All Essential Forms & Schedules Included with Each Filing
When you file your S Corporation (Form 1120-S) or Partnership (Form 1065) return with TaxZerone, you gain access to a wide range of supporting forms and schedules required for accurate IRS filing — all included at no extra cost. This helps ensure your return is complete, compliant, and ready for e-filing.

Commonly Used Supporting Forms

✔️ Form 4562 – Claim depreciation and amortization
✔️ Form 8825 – Report rental real estate income and expenses
✔️ Form 1125-A – Report cost of goods sold
✔️ Form 1125-E – Report compensation of officers
✔️ Form 7205 – Claim energy-efficient building deductions
✔️ Form 8949 – Report sales of capital assets

While many traditional tax software platforms rely on complex interfaces and manual steps, TaxZerone is designed with a technology-driven approach that simplifies the entire process.

The platform includes built-in validation tools that automatically check for missing fields, calculation errors, and incomplete sections before submission. These automated checks help reduce mistakes and ensure returns are ready for filing.

From entering business details to generating Schedule K-1s and completing required schedules, every step is designed for accuracy, efficiency, and a smoother filing process.
