Last weekend, while walking through a botanical garden with a friend, I heard an unexpected story. He found out that his parents' house was subject to Massachusetts inheritance tax while organizing their belongings. I always thought federal inheritance tax was just for the wealthy, but the state inheritance tax is a completely different matter.

So, I came home and started looking into it. I was surprised to find that the threshold is lower than I expected.

Massachusetts raised the inheritance tax threshold from $1 million to $2 million with a tax law amendment passed in October 2023. This applies to those who passed away on or after January 1, 2023.

At first glance, it seems generous since the number has doubled. However, this threshold is not indexed to inflation. As home prices rise, the threshold remains the same.

When you compare it, the difference is quite noticeable. The federal inheritance tax exemption limit in 2026 is $15 million per person. This means that a home that poses no concern under federal guidelines could still be subject to state inheritance tax.

In the previous system, there was a so-called cliff. If you exceeded the threshold by just $1, the entire estate was taxed.

The 2023 amendment fixed this issue. With a new maximum tax credit of $99,600, estates valued under $2 million are exempt from tax, and only the amount exceeding that threshold is taxed.

The tax rate is progressive and can go up to 16%. The exact tax amount must be calculated according to the state tax authority's methods, so I wouldn't recommend estimating it roughly.

So, can a single house really push you over the limit? Honestly, it varies by neighborhood. In many cases, a mid-range home in downtown Boston is often below $2 million.

However, in places like Weston or Wellesley, the typical home value according to Zillow exceeds $2 million. In such neighborhoods, it's not an exaggeration to say that a single house could meet the threshold.

More commonly, it's a combination of assets. When you add the home value to retirement accounts, savings, and stocks, you can quickly reach $2 million.

One often overlooked item is life insurance. The death benefit from a policy owned by the deceased can be included in the estate calculation. If you only think of the insurance payout as tax-free, you might miscalculate here.

You also need to be aware of the reporting requirements. If the total estate, including taxable gifts, exceeds $2 million, you must file the Massachusetts inheritance tax return, M-706.

There's a point that can be confusing. The reporting threshold is based on the total estate, while the actual tax is calculated on the taxable estate after deductions, so the two numbers can differ. This means you may need to file a return even if the tax owed is low or nonexistent.

The deadlines are quite tight. Both filing and payment must be completed within nine months of the date of death.

After handling the funeral and paperwork, nine months can pass in the blink of an eye. My friend mentioned that this was the most overwhelming part for him.

If you're married, there's one more thing to be cautious about. Massachusetts does not recognize the portability of the exemption limit between spouses.

While federal inheritance tax allows the surviving spouse to inherit any unused exemption limit from the deceased spouse, Massachusetts does not allow this, which can lead to losing the exemption limit during the first inheritance.

For example, if all the property is in one spouse's name, it could be disadvantageous. This is why discussions about title distribution or trusts often come up in local estate planning.

There's also a recent change. For residents who pass away on or after August 1, 2025, real estate and tangible personal property located outside Massachusetts will be excluded from the taxable estate.

If you have real estate in Korea or other states, be sure to check this aspect. However, determining whether you exceed the reporting threshold may require separate consideration.

As I researched, I realized that inheritance tax is ultimately a task that the surviving family faces amidst their grief.

So, I organized a list of things to do in advance. First, gather a rough total of the house, retirement accounts, insurance, and savings on one sheet.

Next is to verify the titles. Check whose name the assets are in and whether the beneficiaries are up to date.

Then, assess whether a will or trust is necessary based on the scale of the estate. I believe it's best to seek expert advice rather than making this decision alone.

Inheritance tax outcomes can vary significantly based on asset composition, marital status, and assets in other states. Since it depends on personal circumstances, be sure to consult a Massachusetts estate planning attorney or tax professional.

Personally, I find it a bit disappointing that the $2 million threshold is not indexed to inflation. While I understand the need for tax revenue, it seems concerning that even middle-class individuals with a single home are increasingly falling within the scope.

That said, it's not something to be overly afraid of. If you understand the calculation structure and organize things in advance, most mistakes can be avoided.

I think I would casually bring this topic up while taking a walk with my parents this fall. Conversations while stepping on fallen leaves feel less heavy than those at the dinner table.
