Looking for a crypto tax CPA in Massachusetts? We serve clients in Boston.
Massachusetts crypto investors face a flat 5% rate on most income, but the 2023 'millionaire tax' adds a 4% surtax on income over $1.083M (2025; inflation-indexed), bringing the top rate to 9%. A single large crypto sale can trigger this threshold. We help residents from Boston to Cambridge to Worcester plan gain timing, reconcile complex on-chain portfolios, and file accurate federal Form 8949 returns. Garrett Taylor, CPA #133092, prepares federal returns for clients in all 50 states.
Massachusetts added a 4% surtax on income over $1 million (now $1.083M for 2025, inflation-adjusted) in 2023, bringing the top rate to 9%, a dramatic jump for high-earning crypto investors in Boston and Cambridge. A single large crypto liquidation can trigger the millionaire tax, making year-over-year gain timing strategy critical.
With a population of 7.1 million, Massachusetts is home to a significant and growing community of cryptocurrency investors , from Boston to Springfield. Whether you hold Bitcoin, Ethereum, DeFi positions, or NFTs, every transaction creates a federal tax event that must be reported on IRS Form 8949 and Schedule D.
COS Elite provides remote crypto tax preparation for Massachusettsresidents. Garrett Taylor, CPA #133092, is a California-licensed CPA authorized to prepare federal crypto tax returns for clients in all 50 states. Because federal tax law is uniform, your federal return preparation is the same quality whether you're in Boston or anywhere else.
Massachusetts conforms to federal tax treatment on a rolling basis, meaning IRS rules on cost basis, capital gains classification, and crypto reporting requirements apply directly at the state level. The top state rate of 9% applies to crypto gains, stacked on top of federal capital gains tax. Proper reconciliation of your on-chain activity and accurate cost-basis tracking are essential to minimize the combined burden.
Exchanges lose data, wallets get abandoned, and chain history gets fragmented. Reconstructing accurate cost basis across years of trading is the #1 challenge we solve.
Liquidity pool entries, yield farming, cross-chain bridges, wrapped tokens, and restaking events each create taxable moments that most software misses or misclassifies.
Many crypto investors discover years of unreported trades after receiving an IRS letter. We help with back-year reconstruction, voluntary disclosure, and getting compliant without panic.
