Maryland Tax Changes for 2025: What High Earners Need to Know

CBM Contact:Tom Bailey, CPA, CVA

To help close a $3.3 billion budget gap, Maryland Governor Wes Moore has signed off on a new tax plan that raises taxes for high-income residents. The changes include new income tax brackets, a new tax on capital gains, and higher local taxes.

These changes take effect July 1 and will apply to tax filings for the 2025 calendar year.

New Income Tax Brackets

Until now, Maryland’s top income tax rate was 5.75%. Starting next year, high earners will see new tax brackets:

For Single Filers:

  • $250,001–$500,000: 5.75% (no change)
  • $500,001–$1 million: 6.25%
  • Over $1 million: 6.5%

For Joint Filers:

  • $300,001–$600,000: 5.75% (no change)
  • $600,001–$1.2 million: 6.25%
  • Over $1.2 million: 6.5%

New Capital Gains Tax

There will also be a new 2% tax on capital gains for anyone earning more than $350,000.

Exceptions include:

  • Gains from selling a primary home (if the sale price is under $1 million)
  • Property used in a business
  • Retirement accounts like 401(k)s and pensions

✂️ Changes to Deductions

People who itemize their deductions will see a reduction:

  • If you’re married filing separately, deductions are reduced by 7.5% of the amount over $100,000.
  • For all other filers, the reduction kicks in over $200,000.

📍 Local Tax Increases

Counties will now be allowed to raise their income tax rates up to 3.3% (up from 3.2%).

💡 Bottom Line

When combining the new state tax brackets with the higher local tax limit, the top combined income tax rate in Maryland could rise from 8.95% to 9.8% (excluding the 2.0% capital gain tax) for the highest earners.

These changes will have a significant financial impact on many Maryland residents, especially those with high incomes. Now is a good time to speak with your CBM tax advisor to understand how these updates might affect you and to explore tax-saving strategies.

Maryland Adds 3% Sales Tax to Certain Information Technology Services

Starting July 1, Maryland will begin charging a 3% sales tax on a broad array of technology and data-related services while eliminating the exemption for custom software.

The new tax will apply to several types of IT and data services, including:

  • Computing infrastructure providers and data processing
  • Web hosting services
  • Web search portals and online libraries
  • Computer systems design
  • Software publishing

The new law does not apply to the sale of cloud computing to a qualified cybersecurity business.

What About the Regular 6% Sales Tax?

Maryland’s sales tax rate remains 6%, but if a product or service falls under both the regular sales tax and the new 3% tech tax, the higher 6% rate will be used.

New Documentation Required

If you buy digital products or services that will be used in more than one location – or resell them within your business group – you’ll need to provide a “multiple points of use” certificate at the time of purchase. This helps ensure the correct tax rate is applied.

No More Exemption for Custom Software

Previously, custom-made software was exempt from sales tax in Maryland. Now businesses will need to charge or pay tax on custom software just like off-the-shelf products.

💡What This Means for You

Some businesses are still exempt, such as those working with the University of Maryland’s Discovery District or the university’s Applied Research Laboratory for Intelligence and Security. Businesses that sell data services or software in Maryland should evaluate how the law changes could impact their sales tax liabilities.
