I work for a small nonprofit and am trying to build a base to track our required legal filings. I have tried generating formulas and/or automations to help create an auto updating due date field but nothing that I have found to try is working.
The base has 2 tables, one with list of the required filings and one with the submissions, linked to the proper required filing. On the required filings table I have a field with the current due date, a rollup showing the most recent submission date, and a single select field for the frequency of the required filing (annual, etc). I want the current due date to update when the year in the most recent submission and the current due date match. The new due date would be based on the single select field where Annual = advance 1 year, Biennial = advance 2 years, Quinquennial = advance 5 years, and One-Time = remove the date.
For example, if our Form 990 has a current due date of May 15, 2026 and is due annually, when we add the filing listing that it was submitted on March 2, 2026 it should update that current due date to May 15, 2027.
As part of my attempts to make this work I do have a formula field that can serve as an automation trigger, it compares the years and returns “Match” if they match and “No Match” if not.
