Maryland imposes a state personal income tax that flows through to pass-through business owners (sole-prop Schedule C income, partnership / S-Corp K-1 income, LLC pass-through). Rate range: 2% - 5.75% plus county income tax 2.25%-3.2%. Maryland adds a county income tax (2.25%-3.2%) on top of the state rate, pushing combined top rates near 9%. C-Corps are subject to a separate state corporate income tax (rate often near or above the top individual rate). Verify current brackets and any recent rate changes against the Maryland Department of Revenue.
This state offers a Pass-Through Entity (PTE) tax election as a workaround to the federal $10,000 SALT cap imposed by the Tax Cuts and Jobs Act (2017). Eligible pass-through entities (partnerships, S-Corps, LLCs taxed as one of those) may elect to pay state income tax at the entity level on owner shares; the entity-level state tax is then deductible as a federal business expense, bypassing the SALT cap at the individual level. Owners receive a state-level credit equal to their share of the entity-level tax paid. Election is annual; deadlines, computation, and credit mechanics vary by state. Consult a state-licensed CPA before electing.
This state has enacted a 1099-K reporting threshold of $600, lower than the federal floor. Third-party settlement organizations must issue a 1099-K to sellers meeting this lower state threshold even if the federal threshold is not met. Note: receipt of a 1099-K does not change the underlying tax obligation; all business income is reportable regardless of whether a 1099-K is issued. The lower threshold simply means more sellers receive informational reporting. Maryland was an early state-level 1099-K threshold reducer.
The state adopted economic-nexus rules following South Dakota v. Wayfair (2018). Remote sellers without physical presence trigger sales-tax collection obligations once they exceed the state's annual gross-receipts or transaction-count threshold, applied to prior or current calendar year. Marketplace facilitators (Amazon, eBay, Etsy, Walmart) collect on behalf of third-party sellers under separate marketplace laws.
The Maryland threshold typically tracks the post-Wayfair pattern of $100,000 in gross receipts OR 200 transactions in the state in the prior or current calendar year. Verify current threshold structure and any state-specific carve-outs against the state Department of Revenue page linked below.
Maryland LLC formation requires filing Articles of Organization with the Maryland State Department of Assessments and Taxation (filing fee state-specific). Most states require an annual or biennial report filing with a fee. Some impose a franchise-tax minimum on LLCs. Confirm current fees on the Maryland State Department of Assessments and Taxation page.
Maryland generally follows a state version of the federal estimated-tax safe-harbor framework. Most states allow individuals and pass-through owners to avoid an underpayment penalty by paying either (a) 100% of the prior year's state tax liability (110% if prior-year AGI exceeded a threshold, typically $150,000) or (b) 90% of the current year's state tax liability, through a combination of withholding and quarterly estimated payments. Quarterly estimated due dates align with federal (April 15 / June 15 / September 15 / January 15) in most states. Specific safe-harbor percentages, AGI thresholds, and underpayment-penalty rates vary by state; verify against the current state Department of Revenue instructions.
Once the threshold facts are clear, the next question is what they mean for your specific income mix. Use the S-Corp Election Calculator to test whether the salary/distribution split clears the federal break-even given Maryland rates, the Income Tax Pipeline to model federal + Maryland liabilities together, and the Reseller Profit Calculator for 1099-K-affected resale operations.

Yes. Maryland offers a PTE tax election. Eligible pass-through entities elect to pay state income tax at the entity level on owners' shares; the entity-level state tax is then deductible as a federal business expense, bypassing the $10,000 individual SALT cap.

Remote sellers without physical presence in Maryland must register and collect Maryland sales tax once they exceed the state's annual threshold: $100,000 in gross receipts or 200 transactions in the prior or current calendar year. Marketplace facilitators (Amazon, eBay, Etsy, Walmart) collect on behalf of third-party sellers under separate marketplace laws. Verify the current threshold structure against the Maryland Department of Revenue.
See the LLC formation and annual fees section above for Maryland's current formation fee, annual report fee, and any franchise-tax minimum applicable to LLCs. Fees and filing requirements vary substantially state-to-state (from under $50/year in some states to $800+/year in others).
