Peter started preparing tax returns two days after graduating from Bentley University and has never stopped. In 30 years as a Certified Public Accountant he has personally completed over 30,000 returns.
Tax professionals are not all the same. From the “discount” chains to classic accounting firms, many fly through tax season in a disorganized mess and treat clients like a number. Regular taxpayers miss out on legal, safe deductions to the tune of hundreds of millions of dollars in unclaimed refunds every year — and small business owners often overpay.
Here you get personal attention, clear explanations and a friendly approach. Peter has been called “The Most Trusted Tax Professional in the Cape Cod Area.”

Stephen B.“I have personally used Peter Arnold CPA for the past 13 years. Peter’s attention to detail truly makes him a master of his craft.”
