Bonnie Lee, E.A.

Bonnie LeeBonnie Lee is passionate about the one thing that most people hate — taxes.

For over 20 years, as the owner of Sonoma income tax firm Taxpertise and as an Enrolled Agent, Lee has represented taxpayers across the country in audits, offers in compromise, tax problem resolution, and non-filing issues. She specializes in resolving tax problems for independent contractors, the self-employed and small business owners.

Since passing the Internal Revenue Service’s enrolled agent exam on the first try (a rare achievement akin to passing the Bar on the first go round) in 1990, Lee has dedicated herself to making the labyrinthine world of taxes transparent to the average tax payer.

“I realized that I was very good at helping people conquer their fears about the IRS and taxes—two things that most people find incredibly scary and complicated,” explains Lee.

In 2007, Lee mounted her Taxpertise™ seminars and broadcast the first of her weekly Taxpertise™ radio broadcasts on KSVY radio in Sonoma County, California. Her Entrepreneur Press book, Taxpertise, The Complete Book of Dirty Little Secrets and Hidden Deductions for Small Business that the IRS Doesn’t Want You to Know offers readers over 20 years of insider experience in dealing successfully and prosperously with the IRS.

“I wrote the book because I wanted to make the “secret” world of the IRS visible for tax payers,” Lee says. “From a full-scale office audit to offers in compromise and everything in between, Taxpertise ™ deals with it and makes it fear-free and resolvable.”

A native of San Francisco, Lee knew early on that she had a head for business.

“In high school I had the same teacher for American History as I had for Business Law. One day he asked me, ‘You’re a smart girl. Why do you have a C- in history and an A+ in business law?’ I knew right then and there that I was cut out for business and finance,” she remembers.

After attending San Francisco State University, Lee was certified as a tax preparer in 1985 and as an enrolled tax agent in 1990. In 1993 she moved her business from Belmont, California to Sonoma, California and concentrated on Taxpertise and her mission to take the ire out of IRS.

“Through my book, my articles for Entrepreneur.com and FOXbusiness.com and my radio broadcasts I’m reaching out to thousands of taxpayers who are confused, frightened, or just plain concerned that they don’t have all the information to resolve their tax issues,” says Lee. “My mission is enlightenment. The old maxim, ‘Knowledge is power’ could not be more appropriate, when dealing with the IRS. I’m empowering people to claim what’s fair and resolve their problems to become compliant, prosperous taxpayers instead of tax evaders. In the end, that makes the IRS happy, too!”

Bonnie is a member of  the National Association of Enrolled Agents (NAEA) and California Society of Enrolled Agents (CSEA).
