Your company: a Delaware C corporation

The federal and state filings this profile owes, with their dates, from the rules Obligare reads at each agency.

Edit the profile
An LLC's tax treatment decides which federal return it files. Choose the line that matches yours. Nonprofits are covered too.
Count everyone on payroll. An S corporation's working owners are employees: they are paid a salary.
Most Delaware companies are based in another state and owe that state's filings too. If that is you, pick it here.
More about the company: other states, payroll, dates, abroad
Other states where you have employees or an office

Each one adds that state's registration, employer and tax filings. A state where you only keep inventory or make sales belongs under sales tax states below, not here.
Date registered in each other state
Optional. Some states key their report to the day you registered there rather than your date of formation; without it, the formation date stands in and the calendar says so.
States where you collect sales tax
States where you collect sales tax
Needed for states that key filings to the anniversary of formation.
Some taxes start at a revenue threshold.
Outside the United States
Each adds the FinCEN or IRS form that comes with it: the FBAR, Form 5472, Form 5471, Forms 1042 and 1042-S.

No account needed. Nothing is stored until you save it.

Jay, compliance intelligence

I count 38 dated obligations for this profile over the next fifteen months: 13 federal and 25 across Delaware. 4 fall in the next thirty days. The first one that is yours to file, not your payroll provider's: Delaware gross receipts tax return, on October 31, 2026. 3 carry a penalty or a loss of standing if missed; those are marked critical. This assumes the company operates only in Delaware. Most companies formed there are based somewhere else and owe that state's filings too; if that is you, add the state under "Where is it based". No revenue figure was given, so the lines that depend on one stay hidden: Delaware's franchise tax installments, California's LLC fee, Nevada's Commerce Tax, Ohio's and Oregon's gross receipts taxes, New Hampshire's and Tennessee's business taxes. Add a revenue band under "More about the company" to see which apply. A subscription puts all of this in your own calendar app and sends reminders before each date.

Jay sends the link, then a reminder 30 and 7 days before each of your next two dates, free. Nothing else.

Send it to my accountant

One email with the link, from Jay. No list, nothing after.

Window: October 23, 2026 to January 23, 2028. Federal dates that fall on a weekend or holiday are moved to the next business day, as the IRS does. State dates are shown as written; if one falls on a weekend, file before it.

No fixed date

Rules that apply to this profile and carry no date of their own, listed so you know they were considered.

  • Annual meeting of shareholders and directors: Hold the annual meeting of shareholders to elect directors and the directors' meeting to appoint officers, or sign written consents in place of each, and keep the minutes with the company's records. Pick a month and keep it.
  • New hire reporting: Report every new or rehired employee to the state new hire directory within 20 days of the start date (sooner in some states). A payroll provider normally does it with the first payroll.
  • Form I-9 for every employee: Complete Form I-9 for each new employee within three business days of the start date, with the documents it lists, and keep it for three years after hire or one year after the employee leaves, whichever is later. Keep a tickler for work authorizations that expire.
  • Workers' compensation insurance: Keep a workers' compensation policy in force in every state where you have employees, from the first employee in most states, and give the policy renewal date to your calendar as your own date.
  • Workplace posters: Display the current federal posters (minimum wage, OSHA, FMLA where it applies, EEO, employee polygraph protection, USERRA) and your state's posters where employees can see them, and give remote employees electronic copies. Replace them when the agencies update them.
  • Registered agent in every state of registration: Keep a registered agent appointed in the home state and in every state where the company is registered, keep the agent's invoice paid, and update the Secretary of State within the state's deadline if the agent or its address changes. Add the agent's renewal date as your own date.
  • Beneficial ownership report: not required for US formed companies: Nothing to file. Companies formed in a US state are exempt. A company formed under foreign law and registered to do business in a US state still reports.
  • Delaware retirement savings mandate (Delaware EARNS, 5 or more employees): Register with Delaware EARNS if the company has 5 or more employees in Delaware and no retirement plan of its own, then run the employee deductions through payroll; or certify that the company has its own plan.
