Year-End Tax Moves for Equity, Crypto, and Remote Work
There’s still time to act before December 31 — but not much.
If 2025 brought any financial changes — like selling stock, exercising options, moving across state lines, or realizing crypto gains — you may still have ways to reduce what you owe. But many tax strategies have strict year-end deadlines.
Common Triggers That Warrant Action Now:
Stock option exercises or RSU vesting: AMT exposure, 83(b) timing, basis tracking — all time-sensitive.
Significant crypto gains or losses: Loss harvesting and accurate 8949 filing depend on correct year-end treatment.
Moved states or worked remotely across borders: Split residency, income sourcing, and tax credits all require advance planning.
Secondary sales or startup exit: QSBS eligibility, installment treatment, and timing of recognition can impact liability.
Capital gains from investments: Harvesting losses, estimated tax adjustments, and donation strategies are on the table.

2025 RSU Tax Cheat Sheet for Massachusetts Residents
There’s still time to act before December 31 — but not much.
RSUs create ordinary income at vest, which often pushes withholding below the required levels. Many employees discover this only at tax time. Everyone should know few essentials about RSUs.
How Are RSUs Taxed?
Vesting is treated as wages based on fair market value
Sales only create capital gains on the amount above the vest price
Immediate sale usually results in little or no gain
Key 2025 Tax Rates
Federal payroll withholding on RSUs is 22 percent, or 37 percent over 1M
Actual tax owed is often higher than payroll withholding because it depends on your total income
Massachusetts tax is 5 percent plus a 4 percent surtax above $1,083,150
Social Security wage base is $168,600
Medicare is 1.45 percent with an additional 0.9 percent for higher
