Struggling With a Complex Tax Situation?
You’ve worked hard to build and protect your wealth. But when tax season arrives, you find yourself sorting through accounts, investments, and records — unsure if you’re taking advantage of every opportunity to reduce your tax bill.
Sound Familiar?
You only think about taxes in March and April – then stress until filing.
You're making decisions without understanding the tax consequences.
You wonder if you're missing deductions and tax-saving opportunities.
You feel like you're always one step behind on compliance requirements.
You're tired of reactive tax preparation instead of proactive tax planning.
The result? Overpaying taxes, compliance anxiety, and missed opportunities that may have saved you thousands.

"I highly recommend Ned O'Sullivan O'Sullivan Tax & Accounting for all your CPA needs. He did a great job on my year end taxes, and was very pleasant and easy to work with. After my accountant retired, I shopped around for a while and could not find anyone to take on my simple sub-S corporation's taxes. I was so happy to find Ned and am very happy with the results of his service."
