Why Deadlines Matter

Missing Form 5472 triggers a $25,000 penalty per form. State deadlines missed can result in losing your LLC's good standing or even administrative dissolution.

Federal Requirements

All foreign-owned single-member LLCs must file Form 1120 with Form 5472 annually, regardless of income. The standard deadline is April 15 for calendar-year companies.

State Requirements

Each state has different annual requirements. Delaware has franchise tax, Wyoming has annual reports, and some states like New Mexico have minimal ongoing requirements.
