Capital gains tax planning
You want to know what a sale will cost you in tax before you sign. With capital gains tax planning, we run the numbers on a home, rental, stock or business sale while you still have options.
Trial return first. You see the federal and Massachusetts tax on your sale before you commit to it.
Options side by side. We compare timing, holding periods and exclusions so you can pick the lower bill.
Payments set up. We work out the estimated tax you owe on the gain and when to pay it, to keep you clear of underpayment penalties.
How Massachusetts capital gains tax works
You pay capital gains tax in Massachusetts at a rate based on what you sold and how long you held it. The Massachusetts long term capital gains tax is 5%, the same rate as wages.
Massachusetts rate by how long you held the asset
State tax on capital gains, before federal tax
8.5%
Held one year or less
5%
Held more than one year
Collectibles held more than one year: 12% on half the gain.
High earners: 4% surtax on taxable income above $1,107,750 for 2026.

| Gain of $200,000 | Massachusetts rate | Massachusetts tax |
|---|---|---|
| Held one year or less | 8.5% | $17,000 |
| Held more than one year | 5% | $10,000 |
| Collectibles held more than one year | 12% on half the gain | $12,000 |
Illustrative example of state tax only, before federal tax and any surtax.
Sell at least a year and a day after your purchase date and you pay the lower Massachusetts capital gains tax rate. On taxable income above $1,107,750 for 2026, the Department of Revenue charges a 4% surtax.
You also owe federal tax. The IRS applies federal rates of 0%, 15% or 20% to gains on assets held more than a year, based on your income. The IRS adds a 3.8% net investment income tax on gains once your income is above $200,000, or $250,000 on a joint return. Congress has not changed those thresholds since 2013.
How to avoid capital gains tax on real estate, or defer it
You can remove some gains from tax and defer tax on others to a later sale.
Your main home. You can exclude up to $250,000 of gain, or $500,000 on a joint return. You qualify if you owned and lived in the home for 2 of the last 5 years. Massachusetts follows the same exclusion.
Rental and business property. Through a 1031 exchange Massachusetts landlords defer federal tax by buying another investment property. You arrange it before the sale. You name the replacement property within 45 days and receive it within 180 days.
Depreciation on a rental. The IRS taxes the part of your gain from past depreciation at up to 25%. You owe it when you sell.
We work with your qualified intermediary, the firm that holds the sale money, and report the exchange on Form 8824.
If you plan to sell property this year, start capital gains tax planning before you list it.
Ways to reduce capital gains tax that we test in your projection
We run each option through your trial return and show the tax under each.
Sale timing. We split a sale across two tax years, or hold to the one-year mark, and show the tax under each date.
Losses. We offset the gain with losses from other sales in the same year. The IRS disallows a loss when you buy the same stock back within 30 days, so we time any rebuy.
Installment sale. We model the gain spread across the years you receive payments. On Massachusetts gain of $1 million or more, the state needs its own election and security, or it taxes the whole gain in the year of sale.
Gift of appreciated stock. We model a gift of shares held more than a year to charity: you deduct their full value and report no gain.
How a capital gains tax projection works
- 1
Documents.
You send last year's return, recent paystubs and the details of the planned sale.
- 2
Trial return.
We run a full draft return in professional tax software with the sale included.
- 3
Review call.
We walk you through the result and your options on a 30 minute call.
- 4
Payments.
We give you the amount and due date of the estimated payments you owe on the sale.
When the sale closes, we start your federal and Massachusetts returns from the projection.
Send us the sale details and last year's return. We book the review call once the trial return is ready.
What capital gains tax planning costs
We quote the projection once we know what you are selling and what other income you have.
Income sources.
We add time for each extra source, such as equity or rental income.
Type of sale.
We spend less time on a home sale than on a rental with depreciation or a business sale.
Joint returns.
We include your spouse's income sources in the model.
Reporting.
We quote Form 8824 or Section 1202 reporting as part of your tax return.
These are the factors, not a quote. You get the quote before we start.
“they have been extremely helpful, not only with returns, but also with advise on land sales, gift giving, and estate planning.”
