steps to get your taxes filed:

Schedule your Introductory 15-20 MINUTE CONSULTATION

The FIRST step on the path to getting where you want to go starts with an honest conversation. Therefore we will schedule a Phone, Zoom or In-House meeting with you. Please give us a call so that we can provide this 15-20 Initial Consultation. Once we have determined the right direction together we’ll help you stay the course.


During this first meeting we will analyse your current & previous years taxes and address any concerns which we may identify. Thereafter, providing you with our FLAT-RATE offer and ENGAGEMENT LETTER. This formal engagement letter will be sent to you using the DocuSign® tool.
