US Tax Deadline Calendar
Every deadline your LLC must meet in the next 12 months — personalized to how you're taxed and where you formed.
How it works
One form, and the next twelve months stop being a mystery.
Tell us how your LLC is set up
Entity type, state, formation month, and one question: is the owner a non-US resident? That is all the calendar needs.
See your next 12 months
Every deadline that applies to you, in order, with plain-English notes on what each form is and what happens if you miss it. Dates already account for weekends and IRS holidays.
Put it in your calendar
One click downloads the whole year to Google Calendar, Apple Calendar or Outlook, each date with a reminder a week ahead.
What the calendar covers
Built from the filing rules, not a copied list, so the dates stay right every year.
Federal deadlines by entity type
Returns, extensions and estimated payments for single-member, multi-member, S-corp and C-corp LLCs.
State annual reports, all 50 states
Fixed dates and anniversary-based rules alike, plus state taxes such as the California $800 or the Texas franchise report.
Non-US owner filings
Form 5472, 1040-NR, withholding forms and the FBAR, with notes on when each one actually applies to you.
Registered agent and address renewals
Estimated from the month you formed the company. If you bought either service at a different time, your renewal invoice has the exact date.
Calendar download with reminders
The .ics file carries a 7-day alert on every deadline, so your phone nags you before the IRS does.
Frequently asked questions
Is the calendar free?+×
Yes. Building it is free and unlimited. Entering your email unlocks the full date list and the download, and we only use it for occasional compliance tips.
Which deadlines does it show?+×
Everything a calendar-year LLC typically faces in the next 12 months: federal income tax filings and estimated payments, your state's annual report, and extra state taxes where they exist. It does not cover payroll or contractor forms (941, 940, W-2, 1099); if you pay people in the US, ask us about those dates.
I am not a US resident. Does it cover me?+×
Yes, that is a core case. Tick the non-US owner box and the calendar adds Form 5472, Form 1040-NR, withholding installments and the foreign bank account report where they apply. Questions about your setup? Ask our team.
How accurate are the dates?+×
Dates are computed from the filing rules each time you build the calendar, shifted to the next business day when they land on a weekend or IRS holiday. State dates are shown as written in state law. It is general information, not tax advice, so confirm unusual situations with a professional.
Can Amz Consultors just handle the filings?+×
Yes. From US tax filing to annual reports, we can take the whole list off your plate.
