Your LLC's annual deadlines: the complete calendar (and what each miss costs)
An LLC doesn't need attention every day: it needs attention on exact dates, and each one carries its own penalty. This is the full year of a foreign-owned LLC — what's due, when, what forgetting costs — and the anti-forgetting system that takes ten minutes to set up.

Your LLC's year, date by date
April 15 — Form 5472 + pro forma 1120. The most expensive line on the calendar: every foreign-owned single-member LLC files it even with zero revenue. It's informational — no tax due — but skipping it starts at USD 25,000 in penalties. The extension (Form 7004) exists, but must be requested BEFORE the deadline.
Your state's annual report. Wyoming: first day of your anniversary month, minimum fee around USD 60 — missing it costs you good standing. Florida: May 1 for everyone, USD 138.75 — filing late adds a USD 400 penalty. Delaware: LLCs file no report but pay a USD 300 franchise tax by June 1.
June 15 — your personal 1040-NR, if it applies. Non-residents with no US wage withholding have until this date for their personal return. If your LLC had no effectively connected US income, you may not need to file personally — but that conclusion gets verified, not assumed.
All year — the registered agent. The invisible renewal: paid once a year, and the cheap provider won't remind you. If the agent resigns over non-payment, the state can administratively dissolve your LLC — and legal notices stop reaching you exactly when you need them most.
And the BOI? US-formed entities don't file: the exemption began with FinCEN's interim rule of March 26, 2025 and the final rule of August 11, 2026 (in force since August 14) made it permanent. Only companies formed abroad and registered in a US state still file.
The 10-minute anti-forgetting system
Four phone alarms, each one month early: April 15 · your state's date · the registered agent's anniversary · June 15. Four alarms are literally the difference between a compliant LLC and a five-figure penalty.
Amounts and dates are the 2026 reference — some states adjust them; confirm the current year before paying. And if you'd rather someone else carry the calendar (Form 5472 included), that's exactly what the compliance service is for.
