Maryland's PTET election allows pass-through entities to pay state and local income tax at the entity level. Given Maryland's combined state + county rates (up to ~8.95%), this is one of the more valuable PTET elections available.
The R&D Tax Credit (IRC §41) provides a dollar-for-dollar reduction in federal tax liability for qualified research activities. Small businesses can apply up to $500,000/year against payroll taxes. Qualifying activities include developing new products, improving processes, and creating software.
Section 179 allows businesses to deduct the full purchase price of qualifying equipment, vehicles, and software in the year of purchase rather than depreciating over time. The 2026 federal limit is over $1 million. Some states cap or limit Section 179 conformity — check your state rules.
S-Corp owners must pay themselves a "reasonable salary" subject to payroll taxes (15.3%), but remaining profits distributed as shareholder distributions avoid self-employment tax entirely. Optimizing the salary-to-distribution ratio is one of the most impactful tax strategies for business owners earning $60,000+ in net profit.
Qualified Opportunity Zone (QOZ) investments allow you to defer and reduce capital gains taxes by investing in designated economically distressed areas. Gains invested in a Qualified Opportunity Fund (QOF) are deferred until 2026, and if held 10+ years, any appreciation on the QOZ investment is tax-free.
Choosing the right business structure is the single biggest tax decision you'll make. Here's what Maryland LLC and S-Corp owners need to know.
Maryland LLC Formation
Maryland LLCs are taxed as pass-through entities by default. All profits flow to your personal return and are taxed at 5.75% (+ up to 3.2% county tax). Electing S-Corp status can significantly reduce your self-employment tax burden.
LLC vs. S-Corp in Maryland
Maryland offers a Pass-Through Entity Tax (PTET) election — a major advantage for LLC and S-Corp owners. By paying state income tax at the entity level, you bypass the $10,000 federal SALT deduction cap and deduct the full state tax bill on your federal return.
Top LLC Write-Offs in Maryland
Maryland LLC owners can deduct: business expenses (IRC §162), home office (IRC §280A), vehicle mileage (IRC §179), Section 179 equipment expensing, retirement contributions (Solo 401k or SEP-IRA), health insurance premiums, and business meals. Note: Maryland does not conform to federal bonus depreciation — an add-back on your state return may be required.
