Personal attention. Practical answers. A plan for the decisions ahead.
We believe tax work should help you make informed decisions throughout the year, as well as prepare for filing season. Our focus is tax planning for individuals: understanding your situation, looking ahead, and helping you understand the tax side of your decisions.
Our practice
James Maguire is our primary tax preparer, supported by his wife, Meredith, and others who help our practice run. We work together to help clients gather their records, get their questions answered, and move through the preparation process.
Based in Millis, Massachusetts, we work with clients nearby and across the country. We want you to know who you’re working with and feel comfortable asking questions.


Tax planning for everyday decisions
A tax return looks back. Tax planning helps you look ahead. A change in income, a move, retirement, or a decision about saving can raise questions long before it’s time to file.
Our goal is to help you understand the tax side of those choices and how they fit into your day-to-day finances. We focus on practical guidance you can use, with attention to your circumstances and the dollars that matter to you.

Experience that shapes our approach
James graduated from SUNY Maritime College and sailed as a ship’s engineer before turning his focus to taxation. That experience helped shape an approach grounded in understanding how things work, paying attention to details, and explaining them clearly.
He holds an MST, a Master of Science in Taxation, from Northeastern University. After earning his degree, he went on to teach accounting and taxation at Northeastern.
Today, that background informs our work with individuals who want to plan thoughtfully, understand their options and the tax side of their decisions.
A history we’re honored to carry forward
James’s early training came from his father, Kevin Maguire, an attorney who focused on taxation. He values that training for the understanding it gave him of taxation from different perspectives, including the legal side.
Our client relationships also reach back through Kevin’s partners, including John Mulvehill. John was a bomber pilot during World War II and began preparing taxes after returning home from the war.
We still work with clients whose connection to the practice began with Kevin and his partners, as well as later generations of their families. Some of those relationships date back to John’s earliest clients after World War II.
We consider it an honor to carry those legacies forward. They reflect the trust and relationships built over nearly 80 years, and we value the opportunity to continue serving those families.
