Accounting & Tax Services in Maryland, MD
Maryland’s economy is powered by its proximity to Washington, D.C. and a concentration of federal agencies including the National Institutes of Health, the National Security Agency, and the Social Security Administration. The state’s biotech corridor along I-270 from Bethesda to Frederick houses hundreds of pharmaceutical and life sciences companies, while the Fort Meade/NSA campus anchors a $7.8 billion cybersecurity industry. Baltimore’s Johns Hopkins University and Hospital drive $9.1 billion in annual economic impact, and the Greater Baltimore region received a federal Tech Hub designation for predictive healthcare technologies. Maryland’s 620,000+ small businesses face one of the nation’s highest combined tax burdens with state income tax up to 5.75% plus county surcharges reaching 3.2%. SDO CPA works with Maryland business owners across biotech, cybersecurity, and government contracting to maximize the PTET election, structure S-Corps to minimize the combined state-county tax burden, and manage multi-state compliance for businesses operating across the DC-MD-VA corridor.
Maryland Tax Planning Tip
Maryland’s combined state and county income tax can reach 8.95% (5.75% state + 3.2% county in some jurisdictions). The pass-through entity tax (PTET) election is critical for S-Corp and partnership owners because it lets the entity pay both state and county tax, generating a federal deduction that bypasses the $10,000 SALT cap. This is especially valuable in high-tax counties like Howard, Montgomery, and Prince George’s.
