How are the dates and deadlines calculated?

This is an important issue that is often misunderstood. The dates and deadlines related for lien and bond claims are based off the month and year in which the work was actually performed. The invoice date and company accounting methods are irrelevant for these claims.
The important issues are when the work was actually performed and the value of the work for each individual month.
A helpful example? Assume that a contractor completed a three-month painting project that lasted from January to March. The contractor would need to separately identify the value of the work performed for January, February, and March. It would not matter if only one invoice was issued at the end of the project.
The deadlines will vary depending on the type of document and the type of contractor or supplier. General deadlines can be found in the chart below.

IMPORTANT, IF THE 15th OF THE MONTH FALLS ON A WEEKEND OR A HOLIDAY, THE LAST DAY TO FILE A LIEN WILL ALWAYS MOVE TO THE EARLIEST BUSINESS DAY.
