How to Start a Cleaning Service in Maryland (2026)

Three things make Maryland’s cleaning service environment different from neighboring states. First, Maryland is one of only 23 states that taxes cleaning services as a sales-taxable service — but only on the commercial / industrial side, with residential cleaning fully exempt. Under COMAR 03.06.01.01 and MD Code, Tax-Gen § 11-101 et seq., cleaning of commercial or industrial buildings (floor, carpet, wall, window, ceiling, exterior, and general janitorial services) is taxable at 6% state sales tax; residential cleaning is exempt. This split means most growing Maryland cleaning businesses face a critical model decision: residential focus (no sales tax, but lower-margin per home) vs. commercial focus (higher revenue per contract but 6% sales tax adds invoice complexity). Second, Maryland’s $15 statewide minimum wage with three counties imposing higher floors (Montgomery County up to $17.65; Howard County up to $15.50; PG County $15.30) hits cleaning crews particularly hard since cleaning is labor-intensive and most of the cost base is wages. Third, Maryland is an aggressive worker-classification audit state — the Department of Labor and Comptroller treat cleaners working under your supervision as W-2 employees, not 1099 contractors, regardless of paperwork. Misclassification triggers retroactive workers’ comp, sick leave accrual, payroll taxes, and unemployment insurance.

Maryland’s cleaning market is anchored by Montgomery County and Howard County high-end residential, Baltimore City and DC metro commercial property management contracts, BWI/Aberdeen federal facility commercial cleaning, and Eastern Shore vacation-rental turnover cleaning (Ocean City, St. Michaels). The state’s workers’ comp at 1 employee, Healthy Working Families Act sick leave (paid for 15+ employees, unpaid for under-15), and FAMLI program (delayed to 2027 contributions) all apply. This guide covers the residential vs. commercial sales tax split, county-level minimum wage compliance, worker classification rules, and the major-jurisdiction operating considerations.

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

Step 1: Form Your Maryland LLC

File Articles of Organization through Maryland Business Express (SDAT) for $100 standard or $150 expedited. The annual SDAT $300 Personal Property Return is due April 15 — auto-waived if you participate in MarylandSaves payroll deductions. For small cleaning operations with 1-3 employees, MarylandSaves auto-IRA setup eliminates the $300 fee.

Step 2: Decide Residential vs. Commercial vs. Both

Maryland’s sales tax treatment depends entirely on customer type:

Service Type	Taxable at 6%?	Examples
Residential cleaning	EXEMPT (not taxed)	Single-family homes, condos, apartments, townhomes occupied by individuals
Commercial / industrial cleaning	TAXABLE at 6%	Offices, retail stores, factories, warehouses, commercial common areas, exterior commercial cleaning
Janitorial services (commercial buildings)	TAXABLE at 6%	Recurring janitorial service contracts
Floor / carpet / wall / window / ceiling / exterior cleaning of commercial buildings	TAXABLE at 6%	Even one-time deep cleans
Common-ownership community common areas (specific exemption SB 283 of 2019)	EXEMPT	Classrooms, dining, offices, recreation in HOAs and retirement communities
Move-out / move-in cleaning of residential	EXEMPT	Individual residence preparing for sale or move
Move-out / move-in cleaning of commercial	TAXABLE	Office turnover, commercial space prep
Vacation rental turnover (residential, Ocean City, etc.)	EXEMPT	Individual-owned vacation rentals

Strategic implications:

• Residential-only: Simpler invoicing, no sales tax registration needed (but still LLC + workers’ comp at 1+ employee)
• Commercial-only: Higher contract values, but must register sales tax license, charge 6% on every invoice, file monthly/quarterly returns
• Both: Most complex — must clearly separate residential vs. commercial revenue on every invoice and properly remit only the commercial portion as sales tax

Most growing Maryland cleaning businesses end up specializing in one or the other to avoid hybrid bookkeeping and audit risk.

Step 3: Register for Maryland State Taxes

Register through Maryland Tax Connect:

• Sales and use tax license (free) — required if you’ll do any commercial cleaning. Charge 6% on commercial invoices, remit monthly or quarterly depending on volume. Maryland has no local sales tax on top
• Resale exemption considerations: A Maryland janitorial company may purchase paper towels tax-free using a resale certificate IF those towels stock the bathroom of a customer receiving taxable cleaning services. However, the company pays sales tax on cleaning agents used to clean the bathroom (consumed in the service, not resold)
• Employer withholding for state PIT plus county piggyback (2.25%-3.20% depending on where employees live)
• Unemployment Insurance registration — required at first employee

Step 4: Get General Liability and Janitorial Bond Coverage

Standard insurance for Maryland cleaning service:

• General liability: $1M is the floor; $2M typical for commercial cleaning contracts. Covers slip-and-fall, property damage, equipment damage during cleaning
• Janitorial bond (theft / dishonesty): $10K-25K bond is standard, costs ~$100-300/year. Frequently required by commercial property management clients. Covers theft of items by your cleaning crew during service
• Commercial auto: Required for any vehicles used in business operations
• Tools and equipment / inland marine: Coverage for vacuums, floor machines, supplies in transit

Commercial property management clients (REIT-managed buildings, large office complexes, federal facilities) often require specific insurance certificate language with additional-insured endorsement. Federal facility cleaning contracts (NIH, FDA, BWI) typically require $2M+ general liability and contracted-employee fingerprint clearances.

Step 5: Get Workers’ Compensation Insurance at First Employee

Maryland workers’ comp at 1+ employee. Cleaning service NCCI class codes:

• NCCI 9014: Building Service Contractor (commercial / industrial cleaning)
• NCCI 0917: Domestic Service (cleaning in private residences)

Premium typically $1,500-6,000/year for small operations depending on payroll, class code mix, and experience modifier. Maryland’s competitive workers’ comp market is anchored by Chesapeake Employers Insurance (CEIWC), the state-operated insurer of last resort, which reduced rates by 4% effective April 1, 2026.

Step 6: Comply With Maryland Minimum Wage by County

Maryland’s $15 statewide minimum wage with three counties imposing higher floors:

Jurisdiction	2026 Minimum Wage	Effective
State (default)	$15.00	1/1/2024
Montgomery County (≤10 employees, small)	$15.50	7/1/2025
Montgomery County (51+ employees, large)	$17.65	7/1/2025
Howard County (≤14 employees, small)	$15.00	1/1/2026
Howard County (15+ employees, large)	$15.50	1/1/2026
Prince George’s County (uniform)	$15.30	1/1/2026
Tipped wage (statewide)	$3.63 (cleaning generally not tipped)	—

Multi-county cleaning crews must be paid the higher county rate for hours actually worked in that county. A Frederick-based cleaner servicing Bethesda accounts is entitled to Montgomery County’s minimum (potentially $17.65 if employer has 51+ employees) for hours in Bethesda, even if the home office is in Frederick. GPS-time-tracking software with county-zone logic is increasingly standard for multi-county cleaning operations.

Step 7: Comply With Maryland Healthy Working Families Act Sick Leave

The Maryland Healthy Working Families Act applies to all Maryland cleaning service employers:

• 15+ employees: Must provide PAID earned sick and safe leave
• Under 15 employees: Must provide UNPAID earned sick and safe leave (still job-protected)
• Accrual: 1 hour per 30 hours worked, max 40 hours/year accrual cap
• Carryover: Up to 64 hours can carry over year-to-year
• Eligibility delay: Cannot use during first 106 calendar days of employment
• Permitted uses: Employee or family illness, preventive care, parental leave, domestic violence absences

Code 1 hour per 30 hours worked into your payroll software from day one. Penalty for willful violation: $1,000 civil penalty per employee plus back-leave compensation.

Step 8: Address Worker Classification Carefully

Maryland’s Department of Labor wage-and-hour division and the Comptroller of Maryland actively audit cleaning service worker classification. Most cleaners working under your supervision are W-2 employees, not 1099 independent contractors, even if you call them contractors. Maryland uses the IRS common-law factors plus state wage law standards. A cleaner is generally a W-2 employee if you:

• Set their schedule
• Supply cleaning materials, equipment, or chemicals
• Direct cleaning methods or sequence
• Take payment from the client (rather than the cleaner billing the client)
• Operate them as part of regular crews
• Pay them hourly rather than per-job

Misclassification consequences:

• Retroactive workers’ compensation premium plus penalties
• Retroactive sick leave accrual
• Retroactive payroll tax obligations (state withholding, county piggyback, federal FICA, FUTA)
• Retroactive unemployment insurance contributions
• Wage-and-hour back-pay claims for missed minimum wage and overtime
• Civil penalties

If your business model genuinely uses self-directed independent contractors (e.g., cleaners with their own LLCs who set their own pricing, rotate among multiple agencies, supply their own equipment), document the relationship in writing and operate consistently with it. Otherwise, hire as W-2 from day one.

Maryland Cleaning Service Market: Where the Demand Is

• Montgomery County (Bethesda, Potomac, Chevy Chase, Rockville, Silver Spring): Wealthiest US county by median income; high-end residential cleaning at $200-500+ per visit; recurring weekly/biweekly services; demand for green/eco-friendly cleaning. Federal employee/contractor demographic with stable disposable income
• Howard County (Columbia, Ellicott City, Glenelg): Affluent young-family market; biweekly residential dominant; Columbia HOA contracts for recurring common-area janitorial
• Prince George’s County: Strong commercial cleaning market — federal contractor offices, NASA Goddard, university (UMD College Park), industrial facilities. Significant Hispanic and immigrant cleaning workforce supports both residential and commercial markets
• Baltimore City: Commercial property management contracts (downtown office towers, Inner Harbor, Federal Hill, Hopkins/EBDI campuses); residential cleaning concentrated in Federal Hill, Canton, Mt. Vernon, Roland Park, Hampden
• Baltimore County (Towson, Pikesville, Owings Mills): Suburban residential market; commercial property management for Towson office market
• Anne Arundel County (Annapolis, Severna Park, BWI corridor): Naval Academy adjacent residential, Annapolis state government offices, BWI airport corridor commercial
• Frederick County: Fastest-growing market; new construction post-build cleaning; residential maintenance for DC and Baltimore commuters
• Eastern Shore (Worcester County / Ocean City, St. Michaels, Easton): Vacation rental turnover cleaning is HIGH-VOLUME during May-September peak; off-season demand drops dramatically; second-home owner residential clientele year-round but lower density
• Federal Facilities (BWI, NIH Bethesda, FDA Silver Spring, Aberdeen Proving Ground, Fort Meade): Significant commercial cleaning contracts requiring specific certificate language, fingerprint clearances, US-citizen-only crews. High barrier to entry but durable revenue
• Post-Construction Cleaning: New construction project cleanup contracts (Maryland’s growth markets in Frederick, Howard, PG County drive consistent demand)

Maryland Cleaning Service Distinctive Operating Considerations

1. The residential-vs-commercial sales tax line is the single most important operational decision. Mixed residential-and-commercial books require careful invoice separation, separate revenue codes, and audit-ready documentation. Maryland’s 6% commercial cleaning tax means a $5,000/month janitorial contract is actually $5,300 to the customer ($300 sales tax). Some commercial customers expect the tax to be built into the quoted price; some expect it as a line item. Set expectations clearly.

2. The W-2 vs. 1099 audit risk is high in Maryland. Cleaning is one of the industries most often reclassified by Maryland Department of Labor. If your cleaners use your supplies, follow your schedule, and clean assigned accounts under your direction, treat them as W-2 from day one. The retroactive cost of misclassification is far higher than the operational complexity of running a W-2 payroll.

3. Multi-county minimum wage means a single cleaner’s rate can shift by job. A cleaner servicing accounts in Bethesda (Montgomery), Columbia (Howard), and Frederick must be paid the highest applicable county rate for hours worked in each county. For an employer with 51+ employees, the Bethesda rate is $17.65 vs. Howard’s $15.50 and Frederick’s $15 — substantial swings. GPS time-tracking with county-zone logic is now standard.

4. Maryland’s Healthy Working Families Act applies from day one. Even a 2-employee cleaning company must accrue sick leave at 1 hour per 30 hours worked (unpaid for under-15-employee businesses, paid for 15+). Build the accrual into your scheduling and timekeeping software. The 106-day-of-employment usage delay gives you a ramp-up period for new hires before they can use leave.

5. Federal facility cleaning contracts are durable but high-barrier. Maryland’s federal-government workforce concentration creates major commercial cleaning opportunities at NIH, FDA, NSA, BWI, NASA Goddard, Aberdeen Proving Ground, and Fort Meade. These contracts require specific insurance certificate language, fingerprint clearances for all cleaners, US-citizen-only crews in many cases, and federal contracting compliance (SAM.gov registration, NAICS code matching, etc.). Once landed, contracts typically run 3-5 years with renewal options.

Frequently Asked Questions

Are cleaning services taxable in Maryland?

It depends on the customer type. Cleaning services for COMMERCIAL or INDUSTRIAL buildings are taxable at Maryland’s 6% sales tax rate, including floor cleaning, carpet cleaning, wall cleaning, window cleaning, ceiling cleaning, exterior cleaning, and janitorial services. Cleaning services for RESIDENTIAL customers (individuals’ homes) are NOT taxable. A narrow exemption under SB 283 of 2019 (effective April 30, 2019) covers cleaning of common-use areas (classrooms, dining, offices, recreation) within common-ownership communities and retirement communities. Maryland has no local sales tax on top of the state 6%.

Does Maryland require a license to start a cleaning service?

Maryland does not have a state-level cleaning service license. You need: SDAT LLC formation ($100), a sales tax license through the Comptroller (free, required if you do commercial cleaning), workers’ compensation at 1+ employee, and general liability insurance (recommended). Some counties (Baltimore City, Montgomery County, Prince George’s County) require a local Trader’s License from the Clerk of the Circuit Court. There is no state cleaning industry licensing board.

Do I need workers’ compensation for a Maryland cleaning service?

Yes. Maryland requires workers’ compensation insurance for any employer with 1 or more employees under MD Code, Lab. & Empl. § 9-101 — including a single part-time cleaner. Solo owner-operators with no employees are exempt. Cleaning service NCCI class codes are 9014 Building Service Contractor (commercial) or 0917 Domestic Service (residential household). Purchase from any Maryland-licensed carrier or from Chesapeake Employers Insurance (CEIWC), the state insurer of last resort.

What is Maryland’s Healthy Working Families Act and does it apply to cleaning services?

Yes. The Maryland Healthy Working Families Act (MD Code, Lab. & Empl. § 3-1301 et seq., effective February 11, 2018) requires every Maryland employer to provide earned sick and safe leave. Employers with 15+ employees must provide PAID leave; under-15 must provide UNPAID. Accrual is 1 hour per 30 hours worked, capped at 40 hours per year. Employees cannot use accrued leave during their first 106 days of employment. This applies to cleaners regardless of part-time status.

Should I classify my cleaners as W-2 employees or 1099 independent contractors?

Most Maryland cleaners working under your supervision are W-2 employees, not 1099 contractors. The Maryland Department of Labor and Comptroller actively audit worker classification using the IRS common-law factors and Maryland’s wage law standards. If you set their schedule, supply them with cleaning materials, dictate cleaning methods, take payment from clients, or operate them as part of regular crews, they are employees — regardless of any 1099 paperwork. Misclassification triggers retroactive workers’ compensation premiums, sick leave accrual, payroll taxes, and unemployment insurance contributions, with substantial penalties.

What is Maryland’s minimum wage for cleaning service workers?

Maryland’s $15 statewide minimum wage applies to all cleaning workers in 2026. THREE counties impose higher minimums: Montgomery County $15.50 (small employers, ≤10) up to $17.65 (large employers, 51+); Howard County $15.00 (≤14 employees) to $15.50 (15+); Prince George’s County $15.30 uniform. Crews working across multiple counties must be paid the higher county rate for hours actually worked in those counties, requiring careful time-tracking by location.
