Bitcoin Estate Planning in Maryland: State and Federal Estate Tax Exposure

Maryland occupies an unusual and often uncomfortable position in the landscape of American estate law. It is one of only six states in the country that imposes both a state estate tax and a state inheritance tax. If you hold Bitcoin in Maryland — whether you bought early or have been accumulating over the years — understanding how these two taxes interact with your digital assets is not optional. It is essential.

At a Bitcoin price of $95,000, holding just 52 BTC puts you at the $5 million Maryland estate tax exemption Bitcoin family office minimum requirements. Add in your home, retirement accounts, business interests, and other assets, and many Maryland Bitcoin holders are already deep inside estate tax territory without realizing it. This guide covers everything you need to know about bitcoin estate planning in Maryland, from how both taxes work to the specific strategies that can protect your family's wealth.

How Maryland's Estate Tax Works

Maryland's estate tax applies to the estate — the total value of everything you own at death — before assets pass to beneficiaries. The key details:

• Exemption: $5,000,000 (not indexed for inflation)
• Rates: Progressive, topping out at 16%
• Applies to: Maryland residents and non-residents who own real property or tangible personal property in Maryland
• Portability: Maryland does NOT allow portability of the exemption between spouses

That last point — the lack of portability — is one of the most critical planning failures we see among married Bitcoin holders in Maryland. Under federal estate tax law, when a spouse dies, the surviving spouse can "port" the deceased spouse's unused federal exemption to their own. Maryland does not allow this. Without planning, a married couple in Maryland effectively wastes one spouse's $5 million exemption entirely.

Bitcoin is treated as property for federal and Maryland state tax purposes. The fair market value of your Bitcoin at the date of death — not your cost basis — is what determines estate tax exposure. If you bought Bitcoin at $10,000 and it's worth $95,000 at death, your estate is taxed on $95,000 per coin.

How Maryland's Inheritance Tax Works

Separate from the estate tax, Maryland also imposes an inheritance tax on beneficiaries who receive property from a Maryland estate. This is a fundamentally different tax — it's not the estate that pays it, but the recipient. Here's how it breaks down:

Exempt Beneficiaries (No Inheritance Tax)

Maryland exempts certain "Class A" beneficiaries from the inheritance tax entirely. These include:

• Surviving spouse
• Children and stepchildren
• Grandchildren and lineal descendants
• Parents and grandparents
• Siblings (brothers and sisters)

Non-Exempt Beneficiaries (10% Flat Rate)

Anyone who does not fall into the exempt category is subject to Maryland's flat 10% inheritance tax on the value they receive. This includes:

• Aunts, uncles, nieces, and nephews
• Cousins
• Non-relatives (friends, business partners)
• Domestic partners (in many cases, unless legally married)
• Charitable organizations may also be subject unless properly structured

Maryland Is Not a Bitcoin family office in Texas State

Maryland follows common law equitable distribution — not community property. This distinction matters for Bitcoin holders in a few ways.

In community property states, each spouse typically owns half of all marital property by default. In Maryland, Bitcoin you acquired with your own funds, kept in a separate wallet, and titled in your name alone is generally your separate property. Your spouse may have no automatic ownership interest.

This cuts both ways for estate planning. On one hand, you have cleaner title and greater control over how your Bitcoin passes at death. On the other hand, assets held solely in your name count entirely toward your estate — there's no automatic 50/50 split that might otherwise reduce your taxable estate.

Married couples in Maryland who want to fully utilize both spouses' $5 million exemptions must do so through deliberate trust planning — it does not happen automatically.

The Federal Estate Tax Layer

On top of Maryland's state-level taxes, Bitcoin holders with larger holdings also face the federal estate tax. The federal estate tax exemption — currently $15 million per individual ($30 million for married couples using portability), made permanent under the One Big Beautiful Bill Act signed into law in 2025. The political and legislative environment remains fluid.

For Maryland Bitcoin holders, this means the federal exemption currently provides significant headroom — but the Maryland estate tax at $5 million kicks in well before federal exposure begins. The combination of both state and federal taxes on large estates makes the marginal rate on Bitcoin held at death extremely punitive without proper planning.

Key Estate Planning Strategies for Maryland Bitcoin Holders

1. The A/B Trust (Credit Shelter Trust)

Because Maryland does not allow portability of the estate tax exemption between spouses, the A/B Bitcoin Trust Type Selector tool is one of the most powerful tools available to married Maryland Bitcoin holders. Here's how it works:

When the first spouse dies, assets up to the Maryland exemption amount ($5 million) are placed into a "B trust" (also called a credit shelter trust or bypass trust). These assets are excluded from the surviving spouse's taxable estate while still providing benefits for the surviving spouse during their lifetime. The result: both spouses' $5 million exemptions are fully utilized — potentially sheltering $10 million from Maryland estate tax.

Bitcoin held in a credit shelter trust must be managed carefully. The trustee has fiduciary duties, access to private keys or custodial accounts must be properly structured, and the trust document should explicitly address digital asset management. This is not boilerplate work — it requires counsel familiar with both trust law and Bitcoin custody.

2. Wyoming dynasty trust

Wyoming has emerged as the premier jurisdiction for Bitcoin trusts for several reasons: no state income tax, no state capital gains tax, robust digital asset laws, and some of the most favorable dynasty trust rules in the country — including an unlimited trust duration (some states cap trust duration at 90 years or less).

A Wyoming dynasty trust funded with Bitcoin can potentially shelter appreciation from estate taxes for multiple generations. Maryland residents can establish Wyoming-sited trusts with an independent Bitcoin family office in Wyomingee while still retaining certain beneficial rights. The trust assets fall outside the Maryland estate for estate tax purposes if properly structured.

3. Annual Gift Exclusion

The annual federal gift exclusion allows each person to give up to $18,000 per recipient per year (2024 figure, indexed for inflation) without using any of their lifetime exemption. For a married couple, this doubles to $36,000 per recipient through gift-splitting.

Systematic Bitcoin gifting — transferring fractions of Bitcoin to children or other beneficiaries annually — removes both the principal and all future appreciation from your taxable estate. At current Bitcoin prices, the annual exclusion allows transfer of approximaterially 0.19 BTC per recipient per year without gift tax consequences. Over a decade, across multiple recipients, this compounds meaningfully.

4. grantor retained annuity trust (GRAT)

A GRAT is an irrevocable trust where you transfer assets and retain an annuity payment for a fixed term. If the assets appreciate faster than the IRS hurdle rate (the Section 7520 rate), the excess appreciation passes to heirs completely transfer-tax free.

Bitcoin's volatility makes it both an attractive and risky GRAT asset. A short-term GRAT (2-3 years) funded during a period of Bitcoin price appreciation can transfer significant wealth to the next generation with no gift or estate tax. The risk: if you die during the GRAT term, the assets are pulled back into your taxable estate. Careful structuring is required.

5. charitable remainder trust (CRT)

If you have highly appreciated Bitcoin and want to reduce your taxable estate while generating income, a Charitable Remainder Trust allows you to transfer Bitcoin (avoiding capital gains on the transfer), receive an income stream, and leave the remainder to charity. While this reduces the inheritance passing to family, it can be part of a broader diversified estate plan.

Practical Steps for Maryland Bitcoin Holders

Estate planning for Bitcoin in Maryland requires both legal and technical coordination. Here is a framework for getting started:

1. Inventory and value your holdings: Know exactly what you own, where it's held (hardware wallet, exchange, multi-sig), and at what cost basis. Your estate's Bitcoin holdings will be valued at date-of-death fair market value.
2. Determine your total taxable estate: Add your Bitcoin value to your home equity, retirement accounts (IRAs, 401(k)s are included in your taxable estate), business interests, life insurance, and other assets. If you're anywhere near $5 million as a single person or $10 million as a couple, you have Maryland estate tax exposure.
3. Evaluate beneficiary designations: Review your will, trust, and account beneficiary designations. Ensure beneficiaries for your Bitcoin are Class A (spouse, children, siblings) where possible to avoid the Maryland inheritance tax on top of any estate tax.
4. Establish a credit shelter trust: If you're married and your combined estate exceeds $5 million, an A/B trust structure should be seriously evaluated to prevent waste of the first spouse's exemption.
5. Address digital asset access: Your estate plan must include a mechanism for your executor or trustee to access your Bitcoin. This means documented seed phrase instructions, a multi-sig structure with a trusted co-signer, or institutional custody arrangements. Maryland's Revised Uniform Fiduciary Access to Digital Assets Act (RUFADAA) gives fiduciaries the legal authority to access digital assets — but they still need the technical means to do so.
6. Consult with Bitcoin-aware legal counsel: Standard estate planning attorneys are often not equipped to handle the technical and tax complexities of Bitcoin. Seek counsel with specific digital asset experience.

Maryland RUFADAA and Bitcoin

Maryland has adopted the Revised Uniform Fiduciary Access to Digital Assets Act (RUFADAA). This law gives your designated executor or trustee the legal authority to access, manage, and distribute your digital assets — including Bitcoin — after your death or incapacity, subject to your instructions in your estate planning documents.

However, legal authority does not equal technical access. If your executor cannot find your seed phrase, your Bitcoin dies with you. A properly structured Bitcoin estate plan documents access procedures in a secure, legally structured format — often an encrypted document held by a trusted attorney or included in a sealed addendum to your will.

The Urgency of Acting Now

Bitcoin's price trajectory means that holdings that were below the Maryland estate tax threshold two years ago may now be well above it. Unlike the federal estate tax exemption — which adjusts for inflation and has been periodically increased by Congress — Maryland's $5 million exemption has remained static for years. As Bitcoin appreciates, more Maryland holders will cross the threshold without any change in their behavior or holdings.

With Bitcoin's appreciation and Maryland's state estate tax as active concerns, the planning window has rarely been more important to act within.
