US Corporate Tax Services
Expanding into the United States offers significant growth opportunities, but it also introduces a complex set of federal, state, and cross-border tax obligations. U.S. corporations are generally required to file annual federal income tax returns (most commonly Form 1120), along with state and local filings that may apply even when operations are limited or conducted remotely. Navigating these requirements correctly is critical to managing risk, avoiding double taxation, and maintaining compliance as your business scales.
Our U.S. corporate tax services are designed for Canadian and international businesses operating in or expanding into the United States. We act as a proactive partner, supporting clients with annual U.S. federal and state corporate tax filings, tax accounting and method optimization, ongoing compliance monitoring, and cross-border tax planning. By integrating U.S. tax compliance with entity structure, financing strategies, profit repatriation, and foreign tax credit planning, we help align your U.S. operations with long-term business objectives while maintaining full compliance on both sides of the border.
IRS-Ready U.S. Corporate Tax Compliance for Cross-Border Growth
Operating in the U.S. requires strict adherence to federal filing deadlines and entity-specific reporting rules—often before state tax obligations even come into play. U.S. C corporations typically file Form 1120 by the 15th day of the fourth month following year-end, while S corporations (Form 1120-S) and partnerships (Form 1065) generally file by the 15th day of the third month. Missing or misunderstanding these deadlines can trigger penalties and ongoing compliance issues.
For cross-border businesses, complexity often increases at the multi-state level. Business activity, economic presence, or remote employees can create state filing obligations across multiple jurisdictions, affecting income and franchise tax compliance. In addition, U.S.–Canada corporate groups frequently face international reporting requirements that carry significant penalties even when no U.S. tax is ultimately payable. For example, Forms 5471 and 5472 can result in penalties of $10,000 to $25,000 per failure, while foreign account reporting (FBAR / FinCEN Form 114) applies when aggregate foreign balances exceed $10,000.
We help clients manage these risks by coordinating U.S. federal, state, and international filings into a single, defensible compliance strategy—integrating cross-border structuring, ongoing monitoring, and IRS notice or audit support—so your business remains compliant, efficient, and prepared as it grows across borders.
