Harmony Tax Services offers straightforward tax preparation, bookkeeping solutions, and accounting services.

We also offer financial education seminars and have extensive expertise in supporting self-employed artists, freelancers, and small businesses.

While we bring more than 15 years of tax and bookkeeping experience, Harmony Tax Services focuses on affordable services because we appreciate the financial constraints faced by self-employed artists.

About Us


Tammi Hensch is a classically trained musician and experienced bookkeeper. Recognizing that money matters are often the last thing on a creative person’s mind, she launched Harmony Tax Services in 2006, offering tax services and bookkeeping to Toronto’s musicians, artists and actors. Summers spent working at her father’s accounting firm and years of doing taxes for friends and family helped Tammi to identify the unique challenges faced by artists when managing their books.

While completing her Bachelor of Music Performance at the University of Toronto, Tammi also completed two years of commerce studies. She discovered a love for numbers and the seamless relationship between music and math.

“To me it makes perfect sense—music is numbers,” she explains. “Harmony Tax Services is the perfect dovetailing of disciplines. What you have to do to be a good musician is also what makes you a good accountant. You need attention to detail and the ability to discover themes.”

Tammi is a trained bassist with a classical background and love for rock and roll. Still an active musician, she regularly participates in the Shaw Festival and the Windsor Symphony. She also does freelance musical theatre and choral work throughout Toronto.

Tammi is always reliable and always flexible; I have always been satisfied by my return. Every year I enjoy coming in and catching up with her and knowing my taxes are in good hands! She is just the best.

Carrie Wiebe, Singer & Actor

I have been very pleased with the tax services of Tammi Hensch. As an actor and musician, it is especially important that my accountant have an intimate knowledge of my particular business. I have found Tammi to be very knowedlgeable and dependable, and I am happy to recommend her to my friends and colleagues in my field of work.

Josh Grossman, Artistic Director

Toronto Downtown Jazz

Tax season can be stressful-- especially for a self-employed arts manager-- and it's a relief to work with someone like Tammi Hensch: she brings experience both as a professional musician and a bookkeeper, which means she can relate to the challenges of self-employment. Tammi's great to work with, is happy to answer any questions, and makes the tax filing process easy and painless.

Steve Major, Verge Music Lab

Tammi has been an immense help to me since 2007 by letting me focus on my recording business and leaving the accounting to the experts. Tammi has been 100% reliable and organized, and had provided much guidance over this time. She is always a pleasure to deal with and I'd recommend her without hesitation to anyone looking for skillful yet affordable accounting.

Lauren Wickware, Graphic Designer

I approached Harmony Tax Services when I realized I was spending more time on managing my finances than my clients. Tammi helped me by making my monthly bookeeping, GST/HST, and Income Tax manageable. The result was a seamless system that allowed me to spend more time on my clients and eventually lead to the purchase of a new home. Tammi's connection to  the creative arts gave her a unique perspective and understanding of my business needs. I would recommend Tammi to any small business owner who needs to focus on growing their business.

Jo-Ann Liburd, Communications Consultant

I am thrilled that I chose Harmony Tax Services to handle my tax return. As a freelance consultant, I have used other accountants at tax time and also filed my own. Neither experience was as pleasant, cost-effective, or worry-free as working with Tammi. Right from the start, I felt confident that my filing was in good hands with her. She worked quickly, pointed out opportunities for additional deductions, cross-referenced my previous return to ensure that I hadn't overlooked information in the current year, and answered my questions promptly and clearly. She made the entire process painless, accurate, and worry free.
