Understanding Maryland Inheritance Tax: Exemptions for Lineal vs. Collateral Heirs

Current as of: October 3, 2026 Wills, Trusts & Estates Maryland
In Maryland, lineal heirs like children and spouses, as well as siblings, are completely exempt from the state inheritance tax. However, collateral heirs such as nieces, nephews, cousins, or friends must pay a 10% tax on inherited assets. Navigating these rules typically involves filing documents with the local Register of Wills.

When a loved one passes away, dealing with their estate can feel overwhelming, especially when confusing tax laws are involved. Maryland is one of the few states that imposes both an estate tax and an inheritance tax. Understanding how the inheritance tax works is crucial for residents in cities like Baltimore, Rockville, and Annapolis. Depending on your relationship to the deceased, you might owe a significant portion of your inheritance to the state, or you might owe nothing at all.

Generally, the Maryland inheritance tax is assessed on the privilege of receiving property. Unlike an estate tax, which is calculated on the total value of the deceased person's estate before it is distributed, the inheritance tax is paid by the person who receives the assets. Fortunately, Maryland law offers broad exemptions that protect immediate family members, but extended family and friends often find themselves facing an unexpected tax bill. If you are struggling with these complexities, you can easily find and hire a qualified local lawyer from our US Attorney Directory to guide you through the process.

Who Must Pay the 10% Maryland Inheritance Tax?

Under Md. Code Ann., Tax-Gen. § 7-204, the state imposes a flat 10% tax on the clear value of property that passes to certain individuals. This applies to real estate located in Maryland, as well as bank accounts, personal property, and other assets. The process requires filing the appropriate paperwork with the specific county office, such as the Register of Wills for Baltimore City, Baltimore or the Register of Wills for Montgomery County, Rockville, depending on where the deceased resided.

Exemptions for Lineal Heirs

The good news is that most close relatives do not have to pay this tax. Maryland explicitly exempts lineal descendants and ascendants. According to Md. Code Ann., Tax-Gen. § 7-203, the following individuals are completely exempt from the inheritance tax:

  • Spouses and registered domestic partners
  • Children, stepchildren, and adopted children
  • Grandchildren and great-grandchildren
  • Parents and stepparents
  • Grandparents
  • Brothers and sisters (siblings)
  • Spouses of children (sons-in-law and daughters-in-law)

If you fall into any of these categories, you can receive your inheritance without worrying about this specific 10% tax. However, it is still necessary to file standard probate forms, such as Form 1112, Maryland, Register of Wills, Petition for Administration of Regular Estate, to officially transfer the assets.

Rules for Collateral Heirs

If you do not fit into the exempt categories listed above, you are generally considered a collateral heir. Collateral heirs must pay the 10% tax on the total value of the property they receive. This group typically includes:

  • Nieces and nephews
  • Aunts and uncles
  • Cousins
  • Friends and unmarried, non-registered partners

For example, if you inherit a $200,000 home from your aunt or a close friend, you will generally owe $20,000 in inheritance tax to the state. The executor of the estate is usually responsible for collecting this tax from your share and remitting it to the local agency, such as the Register of Wills for Anne Arundel County, Annapolis.

Specific Exemptions to Keep in Mind

Even if you are a collateral heir, there are a few scenarios where the state allows you to bypass the tax entirely. Understanding these specific exemptions can save you thousands of dollars.

Small Estates and Life Insurance Proceeds

Maryland provides a safety net for smaller transfers. If the total value of the property passing from the deceased to any single person is less than $1,000, no tax is owed. Additionally, proceeds from life insurance policies that are paid directly to a named beneficiary (rather than to the estate) are typically completely exempt from the inheritance tax, regardless of the beneficiary's relationship to the deceased.

Furthermore, under Md. Code Ann., Est. & Trusts § 5-601, if the total value of the estate is under $50,000 (or $100,000 if the surviving spouse is the sole heir), the estate qualifies as a small estate. While this primarily simplifies the probate process using Form 1103, Maryland, Register of Wills, Petition for Administration of a Small Estate, it also helps minimize administrative costs and tax complications.

Inheritance Tax vs. Maryland Estate Tax

It is incredibly common for residents to confuse the inheritance tax with the Maryland estate tax. While the inheritance tax is based on who receives the property, the estate tax is based on the total net worth of the deceased person's property. The Comptroller of Maryland, Annapolis oversees the estate tax, which currently only applies to estates valued at over $5 million. Therefore, a large estate might be subject to the estate tax, but if it is left entirely to children, it will owe zero inheritance tax. Conversely, a modest $100,000 estate left to a friend will owe no estate tax, but the friend will owe the 10% inheritance tax.

How Much Does the Process Cost and How Long Does It Take?

Navigating probate and taxes in Maryland involves standard fees. Under Md. Code Ann., Est. & Trusts § 2-206, the probate filing fees with the Register of Wills are based on the size of the estate, ranging from $0 for small estates under $50,000 to several thousand dollars for massive estates. Lawyer fees typically vary widely, often ranging from $250 to $500 per hour, or they may charge a statutory percentage of the estate.

A typical probate process in Maryland takes about 9 to 12 months to complete, allowing enough time for creditors to make claims and for the executor to calculate and pay any applicable inheritance taxes. Complex estates involving litigation or real estate sales can take well over a year.
