The quarterly calendar every owner should pin up

Wall calendar with marked filing dates

Estimated tax payments, payroll filings, and sales tax deadlines follow the same calendar every year, yet they still arrive as a surprise for most owners we meet. The dates are not the problem — the absence of a visible reminder is.

We ask every client to keep one physical or digital calendar with nothing on it but filing deadlines, marked a full month in advance with a note of what is due and roughly how much to set aside. A second reminder a week out catches anyone who scrolled past the first.

The habit costs ten minutes to set up once a year and removes almost all of the late-filing penalties we see. It also makes the number due far less alarming, because you have already been expecting it since the reminder landed.
