E-File Form 1120-S with Ease: TaxZerone Simplifies S-Corporation Tax Filing

IRS-authorized provider offers a simple, secure, and affordable solution for S-corporation tax compliance.

SAN JOSE, CA, UNITED STATES, September 22, 2025 /EINPresswire.com/ -- S-corporations across the United States now have the option to electronically file Form 1120-S, U.S. Income Tax Return for an S Corporation, through TaxZerone, an IRS-authorized e-file provider.

Form 1120-S is the annual tax return that S-corporations must file to report income, deductions, and other financial details to the Internal Revenue Service (IRS). It includes vital schedules such as Schedule K, which reports income and deductions, and Schedule K-1, which details each shareholder’s share of income. Filing this form on time is crucial to ensure compliance and to avoid costly IRS penalties for late or incomplete submissions. For step-by-step guidance, refer to TaxZerone’s Form 1120-S Instructions

S-Corporation Eligibility
Not every business qualifies to file as an S-corporation. To elect S-corporation status, a company must be a domestic corporation, have no more than 100 shareholders, and issue only one class of stock. Shareholders must generally be individuals who are U.S. citizens or residents, although certain trusts and estates are also permitted. Partnerships, corporations, and non-resident aliens cannot be shareholders.

Eligible corporations must also file Form 2553, Election by a Small Business Corporation, with the IRS to be officially recognized as an S-corporation. Only after the IRS accepts this election can a business file Form 1120-S for its annual return.

TaxZerone’s e-filing service for Form 1120-S is priced at $179.99 per return, with an optional “Pay in advance & Save” discount of 10% on the filing fee. Importantly, there are no hidden costs.
