COVID-19 Tax Season related changes.......

To ensure our staff and clients all stay safe during these uncertain times Abacus Accounting has implemented a new procedure for dropping off tax documents.


1) Before arriving to Abacus Accounting please make sure all of your tax documents are in an envelope with your full name.     

2) When you arrive at our office there is a clear box by our back door with a red lid that is labeled "Drop Off Form"; please fill out this small form and include it with your envelope.                                                 

3) Drop your envelope in the mail slot that goes directly into our lobby. There is a green sign to indicate where this is located.

4) Our tax team will then start processing and contact you with any questions. 


Other options:


1) Tax Documents can be sent via mail. Please mail to:
