Portland Taxman

63 Federal St, Portland, ME 04101

Serving Portland & All of Maine

Our Portland office sits on Federal Street in the heart of the city, steps from the Old Port & the Eastern Prom. From here we work with individuals, families, and business owners across Greater Portland — from Munjoy Hill and the West End to South Portland, Falmouth, and the surrounding towns.

Maine’s economy runs on small business: independent restaurants and retailers, tradespeople and contractors, seasonal and hospitality operators, and a growing base of remote professionals and real estate investors. Each faces its own tax challenges, and each deserves an accountant who understands them. Whether you’re filing a straightforward personal return, managing rental properties, or running an S-corp, our team provides the year-round strategy that keeps you organized and tax-efficient.

You get genuine local presence backed by the flexibility of a year-round remote team — responsive, personal service on your schedule, not just in tax season. For a rundown of the state’s income, property, and sales tax rules, see our Maine tax guide. Comparing firms? See why clients choose us as accountants across Maine. We are also one of the few accounting firms in Maine that works statewide rather than only in Greater Portland.

Small business owners are the core of what we do here. As a small business accountant in Portland, ME, we handle entity selection and S-corp elections, reasonable-compensation analysis, quarterly estimates, payroll setup, and monthly bookkeeping for Maine businesses — from Old Port restaurants and year-round contractors to remote consultants and short-term rental owners.

Working With Us

In Portland, we provide full-service tax and accounting at every stage — from simple annual filings to complex returns for established Maine businesses.

You get more than a once-a-year filing. We deliver proactive strategy and guidance built for long-term results, and we stay reachable all year — not just when the deadline hits.

Everything we do is efficient, well-documented, and repeatable, so you know what to expect season after season: no surprise fees, no wasted meetings, no upsells.

I started working with Nick after I was having challenges figuring out my taxes with a "free" website. He was able to answer all of my questions and get the return done in an incredibly timely fashion. He is knowledgeable and very helpful, and there was no question that I would work with him again

I have been using The Taxman Team and Nick Mascetta for many years, and I couldn’t be more pleased with their service. Even after moving to Florida two years ago, I chose to continue working with them because of their professionalism, responsiveness, and expertise. They are knowledgeable, thorough, and always take the time to answer my questions clearly. I feel confident knowing my taxes are handled accurately and efficiently each year. I highly recommend The Taxman Team and Nick Mascetta to anyone looking for reliable and trustworthy tax professionals.

I had some changes that made me uncomfortable to file taxes on my own this year. It was super easy to contact and get Nick my documents. He has been super helpful and kind in our interactions, and had something for me to review pretty fast. Highly recommended.
Individual tax preparation and planning

Tax Services

For Individuals

Accounting has become a commodity. Taxpayers are not getting the service they need from their tax professional. Most accountants rush through tax returns, do not explain the return to clients, and are unavailable outside of tax season.

At Taxman, we have options for clients. Basic tax preparation includes a detailed explanation of your return. Additionally, we offer options for tax planning and guidance all year long.

Preparing your tax return and getting tax efficient are not the same thing. We offer insights on how to set yourself up for long term success. You may not save much year one, but over the long term, we’ll get you set up to save a lot.

Accounting Services

For Businesses

Most tax & accounting firms are understaffed and overworked. In turn, business owner’s are not getting set up properly, and financial records are often inaccurate and late. This leave’s business owner’s to operate blindly without the information they need.

At Taxman, we provide each of our clients with a team so you get the service you need when you need it.

You need your financials tailored to your specific needs to make sure that your business is moving in the right direction and stays tax compliant. We serve clients in all industries.
