Equity Compensation and Founder Tax Decisions in Boston
Identify the award before estimating its tax
Options, restricted stock, and other equity arrangements do not share one tax timeline. We review the agreement, transfer or exercise dates, vesting terms, price paid, and payroll treatment. Massachusetts can treat compensation connected with services performed in the state as Massachusetts-source income even when the individual later moves away. Massachusetts nonresident compensation rules.
Review eligible restricted-property elections promptly
A Section 83(b) election concerns eligible substantially nonvested property transferred for services and generally must be filed within 30 days of the transfer. It is not an election to make indiscriminately for every equity award. We review eligibility, valuation, restrictions, potential forfeiture, and the filing evidence before recommending a course of action. IRS Section 83(b) election form and instructions.
Project the transaction with the rest of the year
A proposed exercise or sale should be reviewed alongside wages, other gains, deductions, prior payments, and Massachusetts tax rates, including any applicable surtax. We compare the timing and cash required without assuming payroll withholding will cover the final bill. Preserve the records needed to reconcile compensation and investment reporting after the transaction. Massachusetts current tax rates.
How we scope the work
We start with the decision or filing you need to complete, the entities and people involved, and the deadline. After reviewing the available records, we identify missing information and propose the services and deliverables. For ongoing work, we establish a close and filing calendar so bookkeeping, tax projections, and owner reporting use consistent information.
For an audit or other assurance request, bring the lender, grant, board, or regulatory requirement. We confirm the engagement type and applicable professional requirements before accepting the work.
