New Procedures for the Upcoming Tax Season, See New Updated Hours

In response to the Covid-19 virus situation, we have implemented new procedures here at Somersworth Tax Service. These new procedures are meant to minimize the risk of infection for our staff and our clients. With very few exceptions, all taxes will be prepared using our drop box service. There will be no in-person tax prep appointments. If you have a pre-booked appointment you made last year, please instead utilize our drop boxes for your 2020 tax information. Give us a call in advance to let us know you are dropping your information off. After preparing your taxes, we will contact you to explain procedures for submitting your taxes and the payment/refund process. We have two drop boxes. During working hours you can use the drop box just inside the door on the first floor. After hours, if the first floor door is locked, you can use the outside drop box. Both of the drop box bins will be checked constantly throughout the day. Our hours are M-Th. 9am-6pm, Fridays 9am-5pm, Saturdays 9am-3pm. If you would like to e-mail us your info., call us for instructions. Please know that we will be available to our clients primarily by phone at 603-948-1545 for the entire tax season. You are always welcome to call us with any questions you may have. Thank you for your cooperation.
