Your Estimated Maryland Tax:
Understanding Maryland State Taxes
Maryland has a progressive income tax system, meaning that higher income levels are taxed at higher rates. The state also has different tax brackets and rates depending on your filing status. This calculator provides an estimate based on the most recent tax information available.
How Maryland Income Tax Works:
Maryland's income tax is calculated using a series of tax brackets. For each bracket, a specific percentage of your income falling within that range is taxed. The sum of the taxes from each bracket determines your total state income tax liability.
Filing Status Differences:
The tax rates and standard deductions can vary significantly based on your filing status. It's crucial to select the correct filing status for the most accurate calculation.
Key Maryland Tax Rates (Illustrative – Always check official sources for current year rates):
Single: 2% on the first $1,000, 3% on income between $1,001-$2,000, and so on, up to a top rate of 5.75% on income over $15,000.
Married Filing Jointly: Similar brackets but often with higher income thresholds for each bracket compared to single filers.
Married Filing Separately: Generally, the same rates as single filers, but income is split between spouses.
Head of Household: Taxable income thresholds and rates are typically between those for single filers and married filing jointly.
Note: This calculator uses simplified tax bracket information. Actual Maryland tax calculations can be more complex and may include various credits, deductions, and special circumstances. For precise tax advice, consult a qualified tax professional or refer to the official Maryland Comptroller website.
