Maryland Investment Property Taxes and LLC Setup: What Investors Need to Know

Maryland is not a low-tax state for real estate investors. Between state income tax on gains, county income tax on top of that, and a non-resident withholding regime that can tie up your sale proceeds if you don't file the right form at the right time, the tax picture is one area where Maryland deals require more advance planning than most.

Here's what the numbers look like and how to structure around them.

Maryland Capital Gains Tax Rate 2025

Maryland taxes capital gains from real estate as ordinary income — there's no separate preferential rate for long-term gains the way federal law provides a 0%/15%/20% bracket. Your Maryland gain is stacked on top of your ordinary income and taxed at the same rate.

State income tax rate: Maryland's top marginal rate is 5.75% for income above $250,000.

County income tax: Every Maryland county levies its own income tax on top of the state rate. County rates range from 1.75% to 3.20%.

The maximum combined rate in Maryland's highest-rate counties is 8.95% — that's the Maryland-only portion before you add your federal capital gains tax. For federal purposes, most investment property gains are taxed at 20% (plus 3.8% NIIT for high earners). Combined federal + Maryland tax on a gain can reach 32-33% for investors at the top brackets.

The 2025 Budget Reconciliation Act adds a wrinkle: Congress enacted a permanent 2% capital gains surcharge on adjusted gross income over $350,000. This creates a cliff effect — a gain that pushes your AGI from $349,000 to $351,000 triggers the surcharge on the entire amount above $350,000. For investors with multiple properties, staggering sale dates across tax years may be worth modeling.

At peak combined rates: Federal 20% + 3.8% NIIT + 2% surcharge + Maryland 8.95% = 34.75% effective combined rate on a Maryland investment property sale. That's not a marginal-rate scenario that most investors face, but it sets the ceiling, and it explains why 1031 exchanges are extremely popular among Maryland property owners.

Depreciation Recapture

On top of capital gains, remember depreciation recapture. Federal law taxes accumulated depreciation at a maximum 25% rate. If you've held a Baltimore rowhouse for 10 years and claimed $50,000 in depreciation, that $50,000 gets taxed at 25% federal regardless of your other gains — plus it's subject to Maryland ordinary income tax on top.

This is why the exit tax math on long-held investment properties is often more complex than the purchase-price-minus-adjusted-basis calculation suggests.

Maryland Form MW506AE: The Non-Resident Withholding Trap

If you're not a Maryland resident (you bought a Maryland investment property but live in DC, Virginia, Delaware, or another state), Maryland requires buyers to withhold a portion of your sale proceeds and remit it directly to the state.

Withholding rates:

• Individuals: 8% of proceeds (not gain — proceeds)
• Entities (LLCs, corporations): 8.25% of proceeds

On a $300,000 sale, that's $24,000 withheld. The withholding is treated as an estimated tax payment and reconciled when you file your Maryland nonresident return — but if you're doing a 1031 exchange or otherwise don't owe Maryland tax on the transaction, that money is tied up until you file and receive a refund.

Form MW506AE is the solution: Maryland's Application for Certificate of Full or Partial Exemption allows non-residents to apply for reduced or zero withholding before settlement. For a 1031 exchange, you can apply for a full exemption on the grounds that no Maryland tax is owed on the disposition.

Critical timing requirement: You must file MW506AE at least 21 days before the settlement date. Late filing means the settlement agent is required to withhold the full 8%/8.25%, and you'll be waiting for a refund. With Maryland's 30-45 day closing timeline, file as soon as you go under contract.

Filing process:

1. Complete Form MW506AE with the property details, your tax identification, the nature of the transaction, and the basis for exemption
2. Submit to the Comptroller of Maryland's Revenue Administration Division
3. Receive a Certificate of Full or Partial Exemption
4. Provide the certificate to the settlement agent before closing

Non-resident investors — particularly DC-area investors who own Maryland rentals — frequently don't know about MW506AE until a title company mentions it two weeks before closing. By then it's too tight to guarantee approval in time.

Maryland LLC for Investment Property: Costs and Considerations

Many investors hold Maryland investment properties in LLCs for liability protection and estate planning flexibility. Here's what forming and maintaining a Maryland LLC actually costs.

Maryland LLC filing fee: $100 to file Articles of Organization with the State Department of Assessments and Taxation (SDAT). This is a one-time formation fee.

Annual report fee: Maryland LLCs must file an annual report with SDAT. The fee is $300 per year for a domestic LLC — one of the higher annual report fees in the region. Virginia charges $50, Delaware charges $300 but has different trade-offs.

Resident agent fee: Maryland requires a resident agent (physical Maryland address). If you don't have a Maryland office, you hire a registered agent service — typically $50-$150/year.

Total annual LLC cost: $300 (annual report) + $50-$150 (agent) = $350-$450/year to maintain a Maryland LLC.

The tax treatment question: A single-member LLC is a disregarded entity for federal tax purposes — your LLC's income flows to your personal return as if you owned the property individually. This means an LLC doesn't provide any federal tax benefit over individual ownership; it's a liability protection structure.

Maryland recognizes the LLC as a pass-through for income tax purposes. You file a Maryland personal income tax return (or nonresident return if you live elsewhere) reporting the rental income and gains.

Due-on-sale clause warning: Transferring property you financed personally into an LLC can trigger the due-on-sale clause in your mortgage. Most lenders don't enforce it, but technically the transfer is a default event. Either get lender consent or consult a Maryland real estate attorney before transferring financed property into an LLC.

Structuring for Multiple Properties

If you're building a multi-property Maryland portfolio, common structures include:

• One LLC per property: Maximum liability separation. Higher annual report fees ($300 × number of LLCs). Common for properties with significant value or high liability risk (lead paint, older Baltimore rowhouses).
• One LLC for all properties: Simpler management, $300/year total. Liability attaches to all properties through the shared entity if one property has a judgment.
• Series LLC: Maryland does not recognize series LLCs. If you're familiar with the Texas or Delaware series structure, it's not available here.
• Land trust: Some Baltimore investors hold properties in revocable land trusts with an LLC as beneficiary, primarily for privacy. Land trusts don't provide liability protection — the LLC layer does.

Maryland's capital gains treatment and non-resident withholding rules can meaningfully affect your net proceeds if you don't plan ahead. The Maryland Investment Property Guide covers the full tax picture alongside closing costs, licensing requirements, and county-by-county market analysis.
