Welcome to the Boston Tax Institute, Ltd. website. BTI was founded by Lucien P. Gauthier, Esq., LL.M., CPA in 1982 in order to provide top-quality tax and accounting seminars throughout New England. These seminars are designed to keep CPAs and other tax practitioners up to date and informed on the latest tax developments and strategies while helping them meet their relicensing requirements.

Included in this site is our latest seminar information containing detailed descriptions, dates, instructors, and pricing of our online seminars. Due to the coronavirus stay-at-home orders, we have converted all of our seminars to live video conferences. These video conferences will maintain the same personal touch and feel as you have come to expect from us for over 37 years. Participants can ask questions and offer their own relevant experiences in class just as in a live seminar conducted in a conference room or at a hotel.

Lucien P. Gauthier, Esq., LL.M., CPA also provides tax consulting services to CPAs and their clients in areas such as Section 199A, S corporations, reasonable compensation, the accumulated earnings tax, purchases and sales of businesses, complete liquidations, the cash method of accounting and treatment inventory, passive activity losses, valuation matters, abatement of penalties, and representation of clients on audit and at an Appeals Office level.

If you are an attendee of BTI seminars or would like to be informed about major federal and state tax developments, join our Boston Tax Alert e-mail list by filling out the Mailing List Signup on the right-hand side of the page. With our ability to master new provisions quickly when important legislation is passed, such as the PPP loans and other CARES Act legislation, we send out breaking tax alerts with crucial insights and valuable information followed by live video conference dates and times.

We also provide links to other tax-related web sites that you may find helpful.
