Selling an Inherited House in Massachusetts: Probate, Taxes, and Timeline

Most inherited houses in Massachusetts can be sold, but almost never immediately. In most cases the estate has to clear probate first so the personal representative has legal authority to sign a deed, and that step alone commonly runs a few months. On the tax side the news is better: because of the federal step-up in basis, most heirs owe little or no capital gains tax when they sell shortly after inheriting. The part that surprises families is the state estate tax, which reaches lower than the federal one.

I am a real estate agent, not an attorney or a tax advisor. Treat this as general guidance to help you ask the right questions, then confirm the specifics with a Massachusetts probate attorney and a CPA before you act.

### Do I have to go through probate to sell?

Usually yes, unless the property was set up to skip it. If the house was held in a living trust, owned jointly with right of survivorship, or carried a transfer-on-death arrangement, title can pass outside probate and you may be clear to list quickly. If the deceased owned the home in their name alone, the estate generally has to be opened in the Probate and Family Court in the county where they lived, and a personal representative appointed, first.

Massachusetts uses the Massachusetts Uniform Probate Code (MUPC), which offers two tracks. Informal probate is handled administratively by a magistrate rather than a judge, has no hearings, and can move fast. A magistrate can issue an informal order as early as seven days after death if the paperwork is clean and uncontested. Formal probate goes in front of a judge and is used when the will is unclear or missing, an heir is a minor or incapacitated, or there is a dispute. It takes longer and costs more. One note: under the MUPC there is generally a three-year window from death to open probate, so do not leave it sitting.

### What does the step-up in basis do for my taxes?

It resets the property's cost basis to its fair market value on the date of death, which usually wipes out most or all of the capital gains you would otherwise owe. This is the single most important tax fact for inherited property, and it is federal, so it applies the same in Massachusetts as anywhere else.

Capital gains tax is charged on the difference between your sale price and basis. Say your grandmother bought her house in 1978 for 40,000 dollars and it is worth 480,000 dollars when she passes. An ordinary owner would face gain on roughly 440,000 dollars. As an heir, your basis "steps up" to that 480,000 dollar date-of-death value, so selling a few months later for 485,000 dollars leaves taxable gain of about 5,000 dollars, not 440,000.

This is why a defensible date-of-death valuation matters. A dated appraisal or broker price opinion puts your stepped-up basis on paper, protecting you if the IRS ever asks.

### What is the Massachusetts estate tax, and will it hit my estate?

This is the one that catches families off guard. Massachusetts has its own estate tax, separate from the federal one, and it kicks in far lower. For deaths on or after January 1, 2023, the exemption is 2 million dollars (please verify the current figure, as thresholds do change). The federal exemption sits in the multi-millions per person, so plenty of estates that owe nothing federally still owe Massachusetts.

A couple of details matter. The 2 million dollar exemption is not indexed for inflation, so it stays flat until the Legislature changes it. The 2023 reform also fixed the old "cliff," where crossing the threshold taxed the whole estate from the first dollar. Now the estate gets a credit of up to 99,600 dollars, so only value above 2 million is effectively taxed. Estate value includes the house plus retirement accounts and life insurance, which can cross the line faster than people expect. The state lays out the rules on the Mass.gov estate tax changes FAQ. Bring in a CPA, because the estate, not the heir, files and pays.

### How long does the whole thing take?

Plan on a few months from date of death to a completed sale in a clean informal case, longer if probate is contested or the estate is complex.

The estate tax return and payment are generally due within nine months of death, which is why families sometimes sell the house to raise the funds. You do not have to wait for probate to fully close before listing, though. Once the personal representative is appointed, we can market the property while the rest of the administration continues.

### What if I own the inherited house with siblings?

You sell together or one heir buys the others out, and the cleanest path is to agree before the house hits the market. When heirs inherit as tenants in common, every owner generally has to sign the deed, so most families sell and split the proceeds. My job is to give every heir the same honest market data so the decision is about numbers, not suspicion.

### How does this compare to selling across the border?

The federal step-up in basis works identically, but the state estate tax rules differ, so if the property or heirs sit near the line it helps to know both. I handle the Rhode Island side too, and my companion piece on selling an inherited house in Rhode Island walks through that state's version. In border communities like Fall River homes, one agent who works both states keeps the process from getting handed off.

### Frequently Asked Questions

#### Can I sell the house before probate is finished?

Often yes, once the personal representative is appointed. You typically do not have to wait for the entire estate to close. After the PR receives authority, we can prep, list, and go under agreement, then close with the PR signing on behalf of the estate.

#### Will I owe capital gains tax when I sell?

Usually little or none if you sell close to the date of death, thanks to the step-up in basis. Your basis resets to fair market value on the date the owner passed, so you are only taxed on appreciation after that point. Rent it out for years, though, and gains accumulate, so document the date-of-death value early.

#### Does the Massachusetts estate tax come out of my share?

The estate files and pays it before assets are distributed, so it reduces what heirs receive rather than being billed to you personally. That is one reason families sometimes sell the house first. Because the exemption is around 2 million dollars and not inflation-indexed, verify the current threshold with a CPA.

#### What if there is a mortgage still on the house?

The mortgage stays with the property and is paid off at closing from the sale proceeds. If payments are behind, address it early, because lenders can move toward foreclosure even during probate.

#### Do all the heirs have to agree to sell?

Generally yes when heirs own the property as tenants in common, because every owner has to sign the deed. If some want to keep the home, a buyout at the stepped-up value is the usual solution. When agreement is impossible, a court partition action is the fallback, slow and costly enough that a negotiated sale is almost always better.
