Being self-employed in Maryland comes with flexibility and independence, but it also means handling your own taxes. Unlike traditional employees who have taxes withheld automatically, freelancers, contractors, and small business owners must calculate, track, and pay their own federal, state, and local taxes.

Maryland has its own tax structure that can feel confusing if you’re new to self-employment. State income tax rates vary by income, local county taxes apply, and estimated quarterly payments are often required. This guide breaks everything down in simple terms so you know exactly what to expect for the 2025 – 2026 tax years.

Who Is Considered Self-Employed in Maryland?

You’re considered self-employed if you earn income without being on an employer’s payroll. This includes:

• Freelancers and independent contractors
• Gig workers (rideshare drivers, delivery drivers, creators)
• Sole proprietors
• Single-member LLC owners
• Partners in a partnership
• Small business owners without W-2 wages

If you receive income reported on Form 1099-NEC, you are treated as self-employed for tax purposes.

How Maryland Taxes Self-Employed Income

Maryland self-employed workers generally owe three main types of taxes:

• Federal self-employment tax
• Federal income tax
• Maryland state and local income taxes

Each of these works differently, which is why understanding them upfront helps avoid surprises.

Federal Self-Employment Tax Explained

Self-employment tax covers Social Security and Medicare. Employees split this cost with their employer, but self-employed individuals pay the full amount.

For 2025 – 2026, the self-employment tax rate remains:

• 12.4% for Social Security
• 2.9% for Medicare
• Total: 15.3%

This tax applies to your net earnings, not your gross income. That means you subtract business expenses first.

Example: If you earn $80,000 and deduct $20,000 in business expenses, your self-employment tax applies to $60,000.

Federal Income Tax for Maryland Self-Employed Workers

On top of self-employment tax, you also owe regular federal income tax based on IRS tax brackets.

Your taxable income is calculated after:

• Business deductions
• Adjustments like the deductible portion of self-employment tax
• Standard or itemized deductions

Federal income tax rates are progressive, meaning higher income is taxed at higher rates.

Maryland State Income Tax Rates for 2025 – 2026

Maryland uses a graduated income tax system, which means your tax rate increases as your income rises.

Maryland State Income Tax Brackets

Maryland state income tax rates generally range from:

• 2% on lower income levels
• Up to 5.75% on higher income levels

These rates apply to your taxable income after deductions and exemptions.

Local County Taxes in Maryland

One unique feature of Maryland taxes is the local income tax, which applies in addition to state tax.

• Every county and Baltimore City charges a local tax
• Rates typically range from 2.25% to 3.20%
• The rate depends on where you live, not where your clients are

This local tax can significantly increase your total tax bill, especially for higher earners.

Do Self-Employed Marylanders Need to Pay Estimated Quarterly Taxes?

Yes, in most cases.

If you expect to owe $1,000 or more in total taxes for the year, you’re required to make quarterly estimated tax payments.

Estimated Tax Due Dates

• April 15
• June 15
• September 15
• January 15 (following year)

Missing these payments can result in penalties and interest, even if you pay everything at tax time.

How to Calculate Estimated Taxes

To estimate your quarterly payments, you’ll need to consider:

• Expected annual income
• Estimated business expenses
• Federal self-employment tax
• Federal income tax
• Maryland state income tax
• Maryland local county tax

Many self-employed workers overestimate slightly to avoid penalties.

Maryland Sales Tax and Self-Employed Businesses

If you sell taxable goods or services, you may need to collect and remit Maryland sales tax.

Current Maryland Sales Tax Rate

• 6% statewide
• No additional local sales tax

Who Needs to Collect Sales Tax

You generally must collect sales tax if you sell:

• Physical products
• Certain digital goods
• Taxable services

Service-based freelancers (writers, designers, consultants) usually do not collect sales tax, but it’s important to verify based on your business type.

Maryland Business Registration Requirements

Depending on how you operate, you may need to register your business.

Common Registration Steps

• Register your business name if using a trade name
• Obtain a Maryland tax account number
• Register for sales tax if applicable
• Obtain local permits or licenses if required

Sole proprietors without employees may have fewer requirements, but registration is still important for compliance.

Common Tax Deductions for Maryland Self-Employed Workers

Deductions lower your taxable income, which directly reduces your tax bill.

Frequently Claimed Deductions

• Home office expenses
• Internet and phone bills
• Software subscriptions
• Office supplies
• Business insurance
• Vehicle mileage or actual vehicle expenses
• Marketing and advertising costs
• Professional services (legal, accounting)

Only expenses that are ordinary and necessary for your business are deductible.

Home Office Deduction in Maryland

If you use part of your home exclusively and regularly for business, you may qualify for the home office deduction.

You can deduct:

• A portion of rent or mortgage interest
• Utilities
• Property taxes
• Home insurance
• Repairs related to your workspace

This deduction applies at the federal level and reduces Maryland taxable income indirectly.

Vehicle and Travel Deductions

If you use your car for business purposes, you can deduct:

• Mileage using the standard mileage rate
• OR actual expenses like gas, insurance, and maintenance

You must keep detailed records showing business use versus personal use.

Health Insurance Deductions for the Self-Employed

If you’re self-employed and pay for your own health insurance, you may be able to deduct:

• Health insurance premiums
• Dental insurance
• Vision insurance

This deduction reduces your adjusted gross income, which can lower both federal and state taxes.

Retirement Contributions and Tax Benefits

Saving for retirement can also reduce your tax burden.

Popular Self-Employed Retirement Options

• SEP IRA
• Solo 401(k)
• SIMPLE IRA

Contributions are typically tax-deductible and lower your taxable income in Maryland and federally.

What Forms Do Maryland Self-Employed Workers File?

You’ll typically file a mix of federal and state forms.

Common Federal Forms

• Schedule C (business income and expenses)
• Schedule SE (self-employment tax)
• Form 1040

Maryland State Forms

• Maryland Form 502 (resident income tax return)
• Local tax included automatically
• Sales tax filings if applicable

Recordkeeping Tips for Self-Employed Marylanders

Good records make tax filing easier and help support deductions.

What to Keep Track Of

• Income received
• Business expenses
• Mileage logs
• Receipts and invoices
• Estimated tax payments

Keep records for at least three years, though longer is often safer.

Penalties for Late or Incorrect Tax Payments

Failing to meet Maryland tax obligations can lead to:

• Late payment penalties
• Interest on unpaid balances
• Estimated tax penalties
• Additional scrutiny in future filings

Even small mistakes can add up over time, especially for self-employed individuals.

How to Reduce Tax Stress as a Maryland Freelancer

Many self-employed workers struggle with cash flow and surprise tax bills. Planning ahead helps.

Smart Tax Management Habits

• Set aside 25%–35% of income for taxes
• Pay estimated taxes on time
• Track expenses consistently
• Review income monthly instead of annually
• Use tools that simplify budgeting and tax planning

Staying proactive can prevent last-minute financial stress.

Maryland Self-Employed Tax Mistakes to Avoid

Common errors include:

• Ignoring sales tax requirements

Avoiding these mistakes can save hundreds or even thousands of dollars.

When to Consider Professional Help

You may want expert help if:

• You owe back taxes or penalties

Even a single consultation can help clarify your obligations.

Final Thoughts: Managing Self-Employed Taxes in Maryland for 2025 – 2026

Maryland self-employed taxes involve more than just filing a return once a year. Between federal self-employment tax, state income tax, local county taxes, and potential sales tax obligations, planning ahead is essential.

By understanding how Maryland taxes work, tracking expenses carefully, and staying on top of estimated payments, you can avoid penalties and keep more of what you earn. The key is consistency, awareness, and using the right tools to stay organized throughout the year.

If you treat taxes as an ongoing part of your business instead of a once-a-year task, managing self-employment in Maryland becomes far more predictable and far less stressful.
