How to Start a Cleaning Service in Maryland (2026)

Last updated: February 25, 2026

Starting a cleaning service in Maryland has a low barrier to entry. There is no state-level cleaning license required, and you can form an LLC for $100 through the State Department of Assessments and Taxation (SDAT). The key regulatory details to understand are Maryland’s split sales tax treatment (residential cleaning is exempt, commercial cleaning is taxable at 6%), the strict workers’ comp requirement that kicks in at just one employee, and county-level business licensing. This guide covers every requirement from official Maryland sources so you can launch legally and protect your business from day one.

How to Start a Cleaning Service in Maryland (Step by Step)

Step 1: Form Your Business Entity

Register an LLC with the Maryland SDAT ($100 filing fee by mail, or $150 online with expedited processing). File online through Maryland Business Express for faster turnaround (1-2 business days vs. 7-10 days by mail).

If you operate under a name different from your LLC’s legal name, register a trade name with SDAT ($25, valid for 5 years).

Apply for a free federal EIN from the IRS (immediate online). You need this to open a business bank account, hire employees, and file taxes.

Step 2: Get a County Business License

Maryland business licenses are issued at the county level through the Clerk of the Circuit Court. Fees range from $15 to $100 depending on your county. Contact your county clerk’s office for the exact fee and application process.

Standard cleaning services do not require a specialized state cleaning license in Maryland. There is no state-level trade license or certification needed for general residential or commercial cleaning.

Step 3: Register for State Taxes

Complete the Combined Registration Application (CRA) with the Comptroller of Maryland (free). This single application registers your business for sales and use tax, employer withholding tax, and unemployment insurance.

Maryland has a split sales tax treatment for cleaning services:

• Residential cleaning: EXEMPT from Maryland sales tax
• Commercial cleaning: Taxable at 6% state sales tax rate
• Filing frequency: Monthly, quarterly, or semi-annually depending on your volume

This split treatment means if you focus on residential clients, you may not need to collect sales tax at all. If you do both residential and commercial work, you need to track and charge sales tax only on your commercial jobs.

Step 4: Get Insurance Coverage

General liability insurance is not legally mandated by the state for cleaning businesses, but it’s essential in practice. Most commercial clients, property managers, and government contracts require proof of coverage. Typical cost for a cleaning business: $1,300-$1,600/year for $1 million per occurrence / $2 million aggregate coverage.

Workers’ compensation insurance is required in Maryland as soon as you hire one or more employees. This is stricter than many states. Maryland enforces this requirement aggressively, with penalties up to $25,000 for non-compliance. Cleaning businesses typically fall under NCCI code 9014 (janitorial) with rates around $3.50-$6.00 per $100 of payroll. You can obtain coverage through a private carrier or through the Maryland Workers’ Compensation Commission using Chesapeake Employers’ Insurance Company, the state workers’ comp fund.

Step 5: Get Bonded (Recommended)

A janitorial surety bond protects clients against employee theft or dishonesty. While not required by Maryland law, it is an industry standard that many commercial clients and property managers expect before hiring you. A typical $10,000 bond costs $100-$300/year depending on your credit and coverage amount.

Step 6: Set Up Employer Accounts (If Hiring)

The Combined Registration Application (CRA) from Step 3 handles your unemployment insurance (UI) registration. The new employer UI tax rate in Maryland is approximately 2.6% on the first $8,500 per employee per year.

Report all new hires within 20 days via the Maryland New Hire Reporting Center. You can also register with the Maryland Department of Labor for additional employer resources.

Estimated total startup cost: $1,100-$3,500 (solo operator without employees). Add workers’ comp costs as soon as you hire your first employee. Maryland’s $300/year annual report fee is notably higher than many states, so factor that into your ongoing costs.
