Most small operators are not tripped up by the deadline they know about. They are tripped up by the second one — the filing that belongs to a different agency, runs on a different clock, and sends its reminder to an address nobody checks. This page lays out the four recurring deadline families that hit small U.S. businesses, who each one actually applies to, what happens when it slips, and where the official source is. Two of the four changed in the last eighteen months.

This is the filing that keeps your entity in good standing with the Secretary of State. There is no single national deadline, because there is no national filing — each state sets its own. Three patterns cover most of the country: a fixed calendar date the same for every entity in the state, an anniversary date keyed to when you formed, and a tax-year link. A number of states require no recurring report at all, and several run on a two-year cycle rather than annually.
The trap for growing businesses is foreign qualification: register to do business in a second state and you generally pick up that state's report and fee as well, on that state's clock, not your home state's.

Applies to: licensed contractors and trades — general, electrical, plumbing, HVAC and specialty classifications, licensed at state or (in some states) local level.
Two clocks again, and they are not the same clock. The license renewal cycle is usually one to three years depending on state and classification. The continuing-education requirement is a separate obligation with its own hour count, its own approved-provider rules, and sometimes its own reporting step by the provider rather than by you. Some states impose no renewal CE at all; in some, education hours are a pre-licensing requirement that does not repeat. Hours generally do not transfer between states — reciprocity for a license and portability of CE hours are different questions.

Applies to: every employer who pays tipped employees or FLSA overtime. This is the newest item on the list and the one most likely to be missed, because the first year it mattered was forgiving and the second is not.
The One Big Beautiful Bill Act (Public Law 119-21, enacted July 4, 2025) created two new individual deductions for tax years 2025 through 2028: qualified tips, up to $25,000, and qualified overtime compensation, up to $12,500 for single filers and $25,000 for joint filers. Both phase out above modified AGI of $150,000 ($300,000 joint). Only voluntary tips count — mandatory service charges do not — and the tips deduction is limited to occupations that customarily and regularly received tips as of December 31, 2024.
The employer-side duty is reporting. For tax year 2025 the IRS provided transition relief in Notice 2025-62: employers were not penalized for failing to separately report qualified tips, qualified overtime, or occupation codes on Forms W-2. That relief was for 2025 only. Beginning with tax year 2026, these amounts are to be reported separately on Form W-2 — the 2026 form carries new Box 12 codes for qualified tips and qualified overtime and a Box 14b field for the Treasury tipped-occupation code.

Applies to: SEC-registered investment advisers, broker-dealers, investment companies and transfer agents. "Smaller entities" — which for advisers means under $1.5 billion in regulatory assets under management — got the later of the two compliance dates.
The SEC adopted amendments to Regulation S-P in 2024 that turned customer-data protection from a policy document into an operating program. Four requirements sit at the centre: a written incident response program; procedures to notify affected customers within 30 days of determining that unauthorised access to sensitive customer information has occurred or is reasonably likely; oversight of service providers, including a contractual obligation to notify you promptly of a breach; and records documenting all of it.

They rarely arrive together, and that is the problem. The entity report runs on a state clock, license renewal on a board clock, W-2 reporting on the federal tax year, and Reg S-P on a one-time compliance date that becomes a standing program. A business with an LLC in two states, one licensed trade and tipped staff is tracking at least five separate deadlines across four agencies — none of which talks to the others, and most of which notify by mail to the registered agent address.
The practical version of "compliance calendar" is not a wall chart. It is: write down every clock you are on, note which address the reminder goes to, and check that address. Most of the failures in the list above are address failures, not knowledge failures.
