S-Corp Tax Filing (Form 1120-S)

U.S. Tax Preparation for S-Corps from Toronto-Based Enrolled Agents

At SDG Accountant, our U.S. tax specialists support business owners, shareholders, and cross-border operators who require accurate and compliant S-Corporation tax preparation. Whether you are a U.S.-based corporation operating from Toronto or a Canadian expanding into the United States, our team ensures your S-Corp meets all annual filing obligations with the IRS. S-Corporations must file Form 1120-S every year to report income, deductions, credits, and the distribution of profits to shareholders. With increasing IRS scrutiny and complex cross-border rules, proper filing is critical to minimizing tax exposure and avoiding penalties. As Enrolled Agents authorized by the IRS, we provide complete S-Corp tax services with clarity, precision, and year-round support.

What Is an S-Corporation?

An S-Corporation (S-Corp) is a U.S. business entity that provides pass-through taxation, allowing profits and losses to flow directly to shareholders instead of being taxed at the corporate level. This structure can provide significant tax advantages, but it also brings specific reporting requirements.

Every S-Corp—regardless of location, income level, or business activity—must file IRS Form 1120-S annually. Shareholders must also receive Schedule K-1, which reports their share of income for individual tax returns.

SDG Accountant ensures all compliance obligations are met accurately and on time.

Why Filing Form 1120-S Matters

Form 1120-S is the U.S. Income Tax Return for S-Corporations, and it is required each year to:

  • Report business income, deductions, and credits

  • Track shareholder profit allocations

  • Issue Schedule K-1 forms

  • Maintain good standing with the IRS

  • Prevent penalties, interest, and audit risks

Even if the corporation has no activity or no income, the IRS still requires a formal return. Our team ensures every part of the filing is properly completed, reconciled, and compliant with federal tax rules.

Serving Toronto Businesses With U.S. Tax Obligations

Many business owners in Toronto operate U.S. corporations or hold shares in U.S. companies. U.S. tax obligations apply regardless of where the owners live.

We work with:

  • U.S. businesses operating from Canada

  • Canadians owning U.S. S-Corporations

  • Shareholders needing Schedule K-1 reporting

  • Cross-border businesses expanding into the U.S.

U.S. and Canadian tax laws often interact, and without proper planning, cross border income can trigger unnecessary tax exposure. SDG Accountant provides advisory and filing services that ensure full compliance, while identifying opportunities for tax efficiency.

Avoid the head ache of going to tax preparers who claim they file cross border us taxes and outsource it by adding an up charge or end up not filing them properly . Sam and his team are some of the best cross border tax professionals in the city. They really know their stuff. He also helped me file my busIness taxes as I own a barber shop.

I found SDG online when I was looking to register my business and needed someone to help me get a better understanding of the different types of businesses (Partnership/Corporation etc), and tax details. I booked a call with them, and I spoke with Sami. He was very professional, he read the notes I had left when booking the call, he called on time, and answered all my questions.
