Financial Planning on Martha's Vineyard: A Complete Guide

The median home sale price on Martha's Vineyard hit $1.7 million in February 2026, up from $1.5 million a year earlier (O'Hanlon Group, 2026). That single number reshapes almost every financial decision an Island household makes, from how to think about the family home to how much of an estate might owe Massachusetts tax before a single dollar reaches the next generation.

Financial planning on Martha's Vineyard isn't a smaller version of financial planning anywhere else. It's shaped by a seasonal economy, a housing stock where roughly six in ten units sit empty most of the year, and a state tax code that treats a modest year-round life very differently once real estate values climb this high. This guide walks through what actually matters here, not the generic version.

TL;DR

Martha's Vineyard's median home price ($1.7 million as of February 2026, per the O'Hanlon Group) now sits well within range of Massachusetts's $2 million estate tax exemption, and roughly 60% of the Island's housing is seasonal use (Boston 25 News). Financial planning here has to account for real estate wealth, seasonal income, and state-specific tax cliffs that don't show up in most generic advice.

What Makes Financial Planning on Martha's Vineyard Different?

Martha's Vineyard's year-round population sits at roughly 20,933 people, but the Island's peak summer population swells to about 94,650, nearly 4.6 times larger (Martha's Vineyard Commission, 2024). That swing changes everything about how income arrives, how businesses are run, and how real estate gets valued here.

Most financial planning software, and most off-Island advisors, are built around a steady paycheck arriving every two weeks. That model doesn't describe much of the Vineyard. A landscaper, an innkeeper, or a fishing charter captain might earn 80% of a year's income between Memorial Day and Labor Day, then need that money to stretch across a quiet winter with far less coming in.

What We See

In our own client conversations, this pattern tends to show up as a cash flow problem long before it becomes an investment problem. The plan doesn't fail because the portfolio underperforms. It fails because there's no system for smoothing twelve months of expenses against four or five months of income, and by the time that gap becomes obvious, the season that could have funded it is already over.

The Island's median age is 50.7, meaningfully older than the Massachusetts average, and that skews the financial questions we see toward retirement transitions, required minimum distributions, and multi-generational property decisions rather than early-career savings habits (U.S. Census Bureau, 2024).

Layer on top of that a housing stock where seasonal, vacation, or occasional-use units make up an estimated 60% to 61% of all housing on the Island, the highest share of any county in the country alongside neighboring Nantucket (Boston 25 News, 2026). Real estate isn't a side asset for most Vineyard households. For many families, it's the single largest line on the balance sheet, often worth more than every retirement account combined, and it behaves nothing like a diversified portfolio: it's illiquid, concentrated in one location, and tied up in a market that moves on its own seasonal rhythm.

How Vineyard Homeowners Can Plan for Capital Gains

Selling a second home on Martha's Vineyard can trigger federal long-term capital gains tax of up to 20%, plus the 3.8% Net Investment Income Tax (NIIT) for sellers whose modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly), plus Massachusetts tax on top, since the $250,000 (single) or $500,000 (married) home-sale exclusion only applies to a primary residence owned and lived in for at least two of the last five years (IRS,Edelman Financial Engines, 2025). For a property that's appreciated from $400,000 to $1,700,000 million, that distinction is worth real money, and it's easy to end up facing a combined federal rate near 24% before Massachusetts tax is even added.

A few strategies come up often in conversations with Island homeowners:

• Converting the property to a primary residence before selling, which starts the clock on the two-of-five-year rule and can unlock the $250,000 or $500,000 exclusion. This requires an honest change in how and where the family actually lives, not just a change of mailing address.

• Using a 1031 exchange if the home has been used as a rental, even part-time, which lets an owner defer the gain entirely by rolling the proceeds into another like-kind investment property (IRS, FS-2008-18). 

• Tracking capital improvements, a new roof, a kitchen renovation, a septic system upgrade, that raise the cost basis and shrink the taxable gain. Island homeowners who've owned a property for decades often lose track of exactly how much they've put into it, and that paperwork can be worth tens of thousands of dollars at closing.

• Timing the sale for a year when other income is lower, since long-term capital gains rates and the 3.8% NIIT are both tied to income thresholds. A well-timed sale can drop a seller below the $200,000/$250,000 NIIT threshold entirely, not just into a lower capital gains bracket (IRS Tax Topic 559).

Long-term capital gains on the sale of a second home can run as high as 20% at the federal level alone, before any state tax applies, and the common home-sale exclusion doesn't help unless the property was the seller's primary residence for two of the preceding five years (Edelman Financial Engines, 2025).

None of these strategies are unique to the Vineyard. What's different here is the scale. A basis question that might save $3,000 in a typical market can save $60,000 or more when the underlying property has appreciated by seven figures, which is an increasingly ordinary outcome on this Island.

How Does the Martha's Vineyard Land Bank Fee Affect a Real Estate Transaction?

The Martha's Vineyard Land Bank charges a 2% fee, paid by the buyer, on nearly every real estate purchase on the Island, and the deed can't be recorded at the Dukes County Registry until that fee is settled (O'Hanlon Group, 2026). On a $1.7 million median-priced home, that's roughly $34,000 due at closing, on top of every other cost of buying property here.

This is a genuinely Island-specific line item, and off-Island advisors and lenders sometimes miss it entirely when running the numbers on a purchase. The fee funds land conservation directly: since the Land Bank's founding, it has helped conserve about 3,100 acres, roughly 5% of the Island's total land area, protecting it from future development (O'Hanlon Group, 2026).

There's meaningful relief built in for first-time buyers. The first $1,700,000 of a purchase price is exempt from the fee for qualifying first-time homebuyers, an exemption threshold that's adjusted annually (O'Hanlon Group, 2026). Given where the median sale price sits today, that exemption can eliminate the fee entirely for a first home purchased at or near the Island's typical price point, which is worth confirming eligibility for well before an offer goes in.

For move-up buyers and second-home purchasers, though, the fee is simply a cost to budget for, and it's easy to underestimate when a buyer is focused on the purchase price alone. We routinely walk clients through an all-in closing cost estimate before they make an offer, specifically so the Land Bank fee doesn't show up as a surprise line item during the final walk-through of numbers before signing.

Why Does the Massachusetts Estate Tax Matter So Much for Vineyard Homeowners?

Massachusetts taxes estates above $2 million per person, and once an estate crosses that line, the entire estate is taxed, not just the amount above the threshold (Mass.gov, 2026). With the Island's median home now at $1.7 million, a single piece of real estate can push a modest estate most of the way to that cliff before counting a single retirement account or brokerage statement.

This is arguably the most consequential number in this entire guide.

Why It Matters Here

Compare the Island's own median home price, $1.7 million, against the Massachusetts exemption of $2 million per person, and it becomes clear that a great many Vineyard households are one investment account, one life insurance policy, or one strong real estate year away from an estate tax liability they may not know exists. This isn't a high-net-worth problem reserved for the wealthiest families. On this Island, it's increasingly a middle-of-the-road problem.

The federal estate tax exemption sits far higher, at $15 million per person for 2026, which leads some families to assume they're in the clear (Cushing & Dolan, 2025). Massachusetts, however, runs its own separate system entirely. Estates that fall comfortably under the federal threshold can still owe a state estate tax of 0.8% to 16%, reduced by a $99,600 credit for deaths occurring on or after January 1, 2023 (Commons LLC, 2026). For a married couple, the exemption can effectively extend to $4 million combined, but only with the right planning in place ahead of time. It isn't automatic.

For Island families, the planning conversation usually isn't about whether to worry about this. It's about which tools reduce the exposure: an irrevocable trust that removes the home from the taxable estate, a gifting strategy that uses the annual exclusion over multiple years to move ownership gradually, or life insurance sized specifically to cover the expected tax bill so heirs aren't forced to sell the family property just to pay it. Isn't that the exact scenario every multi-generational Vineyard family is trying to avoid?

How Do Seasonal and Self-Employed Business Owners Plan for Retirement?

One in five self-employed workers isn't saving for retirement at all, and among those who do save, about 34% describe it as saving only "from time to time" rather than on any consistent schedule (401(k) Specialist, 2025). On an island where charter captains, innkeepers, and contractors make up a meaningful share of the workforce, that statistic isn't abstract. It's a conversation we have often.

The numbers get more specific, and more sobering, for business owners between 45 and 55. The most common amount saved in that group is around $50,000, far short of the roughly $1.2 million typically recommended for someone earning $120,000 a year, and well behind the $152,100 to $199,900 average 401(k) balance carried by employed peers of the same age (401(k) Specialist, citing the 2025 WealthRabbit Small Business Retirement Report).

Part of the gap is structural, not personal. Only 34% of small businesses offer any retirement plan to employees at all, leaving an estimated 55 million Americans without access to an employer-sponsored plan (401(k) Specialist, 2025). Business owners have to build their own system, typically a SEP-IRA, a Solo 401(k), or a SIMPLE IRA, since there's no employer doing it on their behalf.

The seasonal cash flow pattern common on the Vineyard adds a second layer to this problem. A Solo 401(k) allows contributions as both employee and employer, which matters a great deal when most of a year's income lands in a five-month window. A captain or innkeeper can front-load contributions right after the season closes rather than trying to contribute evenly across months that simply don't generate even income.

What We See

Clients who commit to setting aside a specific percentage of each season's gross revenue for retirement, before spending on anything else, tend to actually hit their savings targets. Clients who plan to "save what's left" at the end of the season almost never do, because there's rarely anything left by October.

What Does the Massachusetts Millionaire's Tax Mean for High-Income Islanders?

Massachusetts adds a 4% surtax on top of its 5% flat income tax rate for any taxable income above $1,053,750 in 2026, creating an effective 9% top marginal rate on ordinary income and a 12.5% rate on short-term capital gains above that threshold (Mass.gov, 2026; CountryTaxCalc, 2026). For a Vineyard household selling a highly appreciated property or business in a single year, that threshold is easier to cross than it sounds.

This is where real estate and income tax planning intersect directly. A homeowner who bought a Vineyard property decades ago for $300,000 and sells it today for $1.7 million or more could realize a gain large enough that, combined with regular income, it pushes well past the $1,053,750 surtax threshold in the year of sale, even if the household's typical annual income is far more modest in any other year.

A few approaches come up repeatedly in these conversations: spreading a business sale across an installment note rather than taking one lump sum, using a charitable remainder trust to defer and spread out a large gain over time, or simply modeling the surtax exposure before a sale closes rather than discovering it afterward. The Massachusetts Budget and Policy Center estimates the surtax will generate about $2.4 billion in state revenue in fiscal year 2026, a reminder that this isn't some niche provision buried in the tax code. It applies to a meaningful and growing share of one-time, high-value transactions across the state, and Vineyard real estate sales are exactly the kind of transaction that triggers it (Mass Budget, 2026).

None of this means avoiding a sale altogether. It means timing it, sequencing it, and knowing the number before the closing date arrives instead of after.

Why Work With a Fee-Only Fiduciary Advisor on Martha's Vineyard?

Only about 4.92% of financial professionals in the United States operate as fee-only fiduciaries, meaning they're paid solely by their clients and are legally required to act in those clients' best interest at all times, not just when recommending a specific product (Human Investing, 2025). On an island where real estate and business wealth are concentrated and complicated, that distinction carries more weight than it might elsewhere.

The fee-only fiduciary model matters because it removes a structural conflict. Most financial professionals in the U.S. earn at least part of their compensation from commissions, product sales, or fees tied to specific investment products, which works fine for plenty of people but creates a natural incentive to recommend whatever pays rather than whatever actually fits.

Among SEC-registered investment advisors, 95.5% offer some form of asset-based fee, but only 17.5% are compensated that way exclusively. The rest blend in commissions or other fee structures alongside it (Human Investing, 2025). A fee-only fiduciary doesn't carry that mix. Advice on whether to convert a Roth IRA, sell a rental property, or restructure an estate plan doesn't shift based on which product happens to be attached to the recommendation.

For Island households juggling seasonal income, concentrated real estate, and a state tax code with real cliffs built into it, that alignment isn't a nice-to-have. It's the difference between a plan built around a client's actual balance sheet and one built around whatever happens to be easiest to sell that quarter.

Frequently Asked Questions

Do I need a financial advisor if I only live on Martha's Vineyard part of the year?

Yes, arguably more than a year-round resident does. Part-year residents often have income spread across multiple states, a property representing a large share of net worth, and tax residency questions that an advisor unfamiliar with the Island may not think to raise before it's too late to plan around them.

How does the Massachusetts estate tax cliff actually work?

Once an estate's value crosses the $2 million exemption ($4 million for a married couple with proper planning in place), the entire estate is taxed, not just the amount over the line, at rates from 0.8% to 16%, reduced by a $99,600 credit (Mass.gov, 2026).

Should I sell my Vineyard home now or wait?

That depends on the size of the gain, your income in the year of sale, and whether the Massachusetts millionaire's surtax threshold ($1,053,750 in 2026) comes into play. A sale modeled in advance, with income and gains sequenced across the right year, often nets meaningfully more than one that isn't planned at all.

What retirement plan makes sense for a seasonal business owner?

For most sole proprietors and small seasonal businesses, a Solo 401(k) or SEP-IRA allows contributions sized to a single strong season, since both plans let a business owner contribute a large share of net income after the season closes rather than requiring steady monthly deposits.

Is Martha's Vineyard financial planning really that different from planning anywhere else in Massachusetts?

In principle, no, the same tax code applies statewide. In practice, yes: median home values near the state's estate tax exemption, a housing stock that's 60% seasonal, and a workforce concentrated in tourism-driven seasonal income make the Island's planning priorities look different from a typical Boston suburb.

The Bottom Line

Financial planning on Martha's Vineyard isn't just about picking investments. It's about recognizing that a median home price near $1.7 million, a housing stock that's roughly 60% seasonal, and a state tax code with real cliffs built into it change the math for nearly every Island household, whether that household earns its income from four months of tourism season or from a portfolio built over forty years off-Island.

The good news is that every challenge in this guide, from the estate tax cliff to seasonal cash flow to the millionaire's surtax, has a known set of planning responses. The families who do best are the ones who model these numbers before a sale, a season, or a transfer happens, not after.
