Freelancing offers flexibility, creativity, and control — but it also comes with responsibilities many new entrepreneurs overlook. One of the biggest? Taxes.
Whether you’re a full-time consultant, gig worker, creative, or part-time side hustler in Maryland, the IRS still expects you to stay compliant. And if you’re not careful, even small mistakes can lead to penalties, audits, or unexpected bills.
This guide breaks down the top tax mistakes Maryland freelancers make, and more importantly — how to fix them.
Mistake #1: Not Paying Estimated Taxes
Unlike traditional employees, freelancers don’t have taxes withheld from their paychecks. You’re responsible for making quarterly estimated payments to the IRS and to Maryland if your withholding and credits won’t cover what you owe. If you don’t, underpayment penalties can apply even if you catch up by April. Federal quarterly due dates are generally April 15, June 15, September 15, and January 15 of the following year (dates shift to the next business day when they fall on weekends/holidays). Maryland uses the same four quarterly cadence.
How to Fix It:
- Use IRS Form 1040-ES or www.irs.gov/payments to pay federal quarterly taxes. For Maryland, pay via Maryland Tax Connect (MTC) or Form PV
- Aim for a “safe harbor” to avoid penalties: pay 90% of current-year tax or 100% of last year’s tax (110% if prior-year AGI > $150,000). Maryland follows a similar standard in Form 502UP instructions
- Set calendar reminders for all four deadlines and adjust payments as income changes
For Maryland self-employed individuals, state estimated payments must also be made separately through the Comptroller of Maryland.
Mistake #2: Mixing Business and Personal Finances
Using the same bank account or credit card for personal and business expenses might seem convenient — but come tax season creates chaos.
It also puts you at risk if you’re ever audited. The IRS doesn’t require a specific system, but you must keep books and records that clearly show income and expenses.
How to Fix It:
- Open a dedicated business checking account and use a separate card for business purchases
- Keep contemporaneous records (invoicing, receipts, mileage logs). IRS Publication 583 explains what to keep and for how long
Maintaining clean records will make it easier to claim freelancer tax deductions and prove legitimacy in case of an audit.
Mistake #3: Overlooking Deductible Expenses
One of the biggest advantages of freelancing is the ability to deduct ordinary and necessary business expenses. But many freelancers either over-claim (raising red flags) or under-claim — leaving money on the table.
Common freelancer tax deductions include:
- Home office expenses
- Internet and phone used for business
- Professional software and subscriptions
- Advertising and marketing
- Travel and meals related to client work
- Education and training
How to Fix It:
- Keep all receipts and categorize them monthly
- Use tools to track mileage and expenses (like MileIQ or Expensify)
- Work with a tax professional who understands Maryland freelancer tax rules
Mistake #4: Misclassifying Your Business Structure
Are you a sole proprietor, LLC, or S-corporation? Many freelancers default to sole proprietorships, but that may not be the most tax-efficient choice.
Improper classification can lead to overpaying self-employment taxes or missing out on legal protections.
How to Fix It:
- Talk to a tax attorney or business advisor about your options
- Consider forming an LLC or electing S-corp status if your income is growing
- Register your business properly with the State of Maryland
This step is especially important if you’re earning consistently or expanding your services.
Mistake #5: Ignoring State Tax Obligations
Federal taxes aren’t the only concern. Maryland freelancers are also responsible for:
- State estimated taxes: Due on the same quarterly schedule as federal (April/June/September/January). You can pay through Maryland Tax Connect.
- Annual business filings / personal property returns:
- LLCs, corporations, etc. file SDAT Annual Report & Personal Property Return (Form 1) by April 15 each year.
- Sole proprietors & general partnerships must file Form 2 if they own/lease/use business personal property in Maryland or need a business license — also due April 15.
- Sales & use tax on digital goods: Maryland taxes digital products (e.g., certain downloads/streaming) at the state sales tax rate — freelancers selling taxable digital goods must register, collect, and remit.
- New 3% tax on certain IT/data services (effective July 1, 2025): Some information technology or software publishing services became taxable at 3%; check current Comptroller guidance to see if your services are in-scope.
- Local business licenses (varies by activity): Many goods-selling businesses need a Trader’s License from the Clerk of the Circuit Court; service-only freelancers often do not, but you must verify based on your activity and county.
How to Fix It:
- Put April 15 on your calendar for SDAT filings
- If you sell digital products or provide taxable tech services, register and set up sales tax collection
- Call your county Clerk of the Circuit Court or use the Maryland Business Licenses resources to confirm if a license is required.
Working with a Maryland-based tax professional can ensure you stay compliant at both the state and federal level.
Mistake #6: Waiting Until Tax Season to Get Organized
Trying to pull everything together in March or April is stressful — and often leads to missing deductions or filing late.
How to Fix It:
- Track income and expenses year-round using accounting software
- Review your finances monthly or quarterly
- Set aside 25–30% of your income for taxes in a separate savings account
Staying organized helps you make smart financial decisions throughout the year — not just at tax time.
Bonus: Overlooking 1099 Forms (Both Receiving and Issuing)
- If a vendor pays you $600+, they generally must issue Form 1099-NEC; you still must report income even if you don’t receive the form. If you pay a contractor $600+ for services, you generally must issue a 1099-NEC by January 31.
- Third-party platforms (PayPal, Venmo, Stripe) — Form 1099-K: For tax year 2024, many platforms issue a 1099-K at $5,000 of payments for goods/services; the IRS plans to move to $600 for 2025 (watch for final IRS updates each season).
