The US Treasury has announced that all tax returns and income tax payments due on April 15, 2020 are now due on July 15, 2020 without incurring any interest or penalties.  This deferral includes any income tax due with the 2019 tax return and the 2020 first-quarter estimate up to an aggregate amount of $1 Million dollars for individuals and $10 Million for C Corporations.   The 2020 second-quarter estimate is still currently due on June 15, 2020.


Most states have not yet issued any 2019 tax relief provisions in relation to COVID-19.  We will provide additional updates as new information from the states becomes available.


For the health and safety of our clients and employees, we are asking that all tax information be sent to us electronically, via one of our secure online file exchanges, or through the mail.  All completed tax returns will be delivered either electronically or through the mail.  We are currently not offering in-person pick up of any tax returns.


Our online tax organizer allows you to answer the questions in the tax organizer and upload your paperwork.  If you have not already requested an online organizer, please email the request to taxdepartment@tss-cpa.com.


We frequently use SafeSend to send tax returns securely to our clients.  Step by step instructions will be sent prior to us sending your return.  If you have not yet opted to use SafeSend, please email us at taxdepartment@tss-cpa.com.


If you need technical assistance with either program, please email taxdepartment@tss-cpa.com or call our office at 603.653.0044.


If it is essential to come to our office, we respectfully ask that you deposit your paperwork into the bin provided in the front lobby.


If you are feeling under the weather, we ask that you refrain from coming into the office.


Thank you, we appreciate your patience during this time.
