I can’t say enough about Cromwell Tax and Bookkeeping. I have never had my taxes done by someone else before, so I wasn’t sure how the process would go. It was easy to set up an appointment, and when I met with Madelyne Cromwell she alleviated any worries I had. She was able to help me sort though everything, and had recommendations for me as this was my first year making a real profit with my small business (yay!). Along the way she was in communication about what else she needed and why, and it was all so easy! Her and her team even helped me set up estimated taxes and logged my business info into my QuickBooks file. I highly recommend this business and will using again next tax year!
