For independent contractors and freelancers mastering "Maryland MHIC Contractor License, Deposit Cap & Tax Rules (2026–2027)", a compliant invoice requires a unique sequential invoice number, legal business/TIN details, itemized scope deliverables, an explicit due date (Due on Receipt or Net 15), and stated late-payment interest terms.
Key Takeaways
- Corporate AP Compliance: When invoicing a company, always match their Purchase Order (PO) number, submit a signed IRS Form W-9 upfront, and specify Net 15 or Net 30 ACH payment details.
- 3-to-7 Year Retention Rule (26 U.S.C. § 6501): Keep all issued client invoices, deposit records, and expense receipts for at least 3 years from tax filing (6 years if underreporting >25%; 7 years for bad-debt write-offs).
- Cash-Flow Velocity: Invoices sent within 24 hours of milestone completion with clear itemization and late-fee disclosures (1.5%/mo) get paid 2.4x faster than unitemized summary bills.
“You must keep your business records—including invoices, receipts, bank statements, and canceled checks—for as long as they may be needed for the administration of any provision of the Internal Revenue Code, generally at least 3 to 7 years.”
Maryland MHIC Contractor License, Deposit Cap & Tax Rules (2026–2027)
Short answer: Under Maryland contractor license requirements (Business Regulation Article, Title 8), anyone who performs, offers, or bids on residential home improvement work in Maryland—repairing, remodeling, painting, roofing, decks, or additions on 1-to-3 family dwellings—must hold a Maryland Home Improvement Commission (MHIC) license, regardless of the dollar value of the job. Applicants need two years of trade/construction experience, a 70%+ score on the PSI exam, $100,000 general liability insurance, and compliance with Maryland’s strict one-third deposit cap.
Unlike states that exempt small handyman jobs under $1,000 or $3,000, Maryland has no dollar exemption for residential home improvement. Performing even a $400 drywall patch, fence repair, or interior painting job on a Maryland home without an active MHIC license is a misdemeanor carrying up to $1,000 in criminal fines or 6 months in jail on a first offense—plus administrative civil penalties of up to $5,000 per violation from the Maryland Home Improvement Commission (MHIC). As contractors prepare for 2026 and 2027 enforcement, understanding how MHIC licensing, the one-third deposit limit, the Guaranty Fund, and Maryland’s 6% contractor sales tax work together is essential.

Who needs an MHIC license in Maryland in 2026–2027?
The Maryland Home Improvement Law (Md. Code, Bus. Reg. § 8-301) requires a contractor license whenever you contract directly with a homeowner to alter, remodel, repair, restore, modernize, or add to residential property (buildings used as residences for 1 to 3 families, plus individual condominium units) or adjacent structures such as driveways, patios, fences, garages, and retaining walls.
- No handyman dollar threshold: There is no “$500 handyman carve-out” in Maryland. If the work falls within the statutory definition of home improvement, you must hold an MHIC license.
- Subcontractors on residential jobs: Following Maryland’s statutory reforms, subcontractors working under a licensed MHIC general contractor are generally not required to hold a separate MHIC subcontractor license unless they contract directly with the homeowner, though trade-specific licenses (Master Electrician, Master Plumber, HVACR) still apply at all times.
- Commercial vs. residential: Purely commercial construction and new-home building are regulated separately—commercial contractors obtain a Construction License through the Clerk of the Circuit Court in the county where the business is located, while new home builders register with the Maryland Home Builder Registration Unit under the Office of the Attorney General.

| MHIC Contractor License | Maryland Dept. of Labor (MHIC) | Any repair, remodel, painting, roofing, deck, or addition on 1–3 family homes | $100,000 general liability insurance + Guaranty Fund assessment + financial solvency |
| State Master Electrician | Maryland Board of Electricians | Electrical wiring, panels, service upgrades statewide | Exam + 7 years experience + county permit registration |
| State Master Plumber / Gas Fitter | Maryland Board of Plumbing | Plumbing & gas piping (except WSSC & Baltimore County special jurisdictions) | Master exam + journey experience + liability insurance |
| State HVACR Contractor | Maryland Board of HVACR Contractors | Heating, ventilation, air conditioning, hydronics & refrigeration | Master/Master Restricted exam + $300,000 general liability + $100,000 property damage |
| Commercial Construction License | Clerk of the Circuit Court (County) | Commercial buildings and non-residential construction contracts | Annual license fee via county clerk + SDAT good standing |
What are the 2026–2027 requirements to get a Maryland MHIC license?
To obtain an active MHIC license for the 2026–2027 cycle, every individual applicant (or the qualifying individual for a corporation or LLC) must complete five steps verified by the Maryland Department of Labor:
- Two years of documented experience: You must prove at least 2 years of full-time trade experience in home improvement work, construction supervision, or a recognized building trade education equivalence.
- Pass the Maryland MHIC PSI Examination: The open-book exam tests Maryland Home Improvement Law (Title 8), contract mandatory disclosures, lien laws, OSHA safety, and business math. You must answer at least 39 out of 55 questions correctly (70%) within 150 minutes.
- Carry at least $100,000 in General Liability Insurance: You must provide a certificate of insurance naming the Maryland Home Improvement Commission as certificate holder with at least $100,000 in general liability coverage.
- Demonstrate financial solvency or post a surety bond: MHIC reviews your personal and business credit history, net worth, assets, and liabilities. If your financial statement does not meet MHIC’s solvency ratio, you can still qualify by posting a two-year MHIC surety bond (historically $20,000 minimum) or an irrevocable letter of credit.
- Pay the application and Home Improvement Guaranty Fund fees: Initial licensing includes a $250 two-year license fee, a $100 Guaranty Fund assessment (which backs consumer claims up to $30,000 per homeowner), and a $20 processing fee, plus registering any LLC or corporation in good standing with the Maryland Department of Assessments and Taxation (SDAT).
What is the Maryland 1/3 deposit cap and mandatory contract checklist?
Maryland enforces one of the strictest residential contract statutes in the United States (Md. Code, Bus. Reg. § 8-617 and § 8-501). Every MHIC contractor must follow two non-negotiable rules on every residential job:
1. The One-Third (33.3%) Deposit Rule
A contractor may not demand or receive more than one-third (1/3) of the total home improvement contract price before or at the time of signing the contract. Demanding a 50% deposit upfront to cover custom windows or roofing materials—without first posting a special performance bond or letter of credit covering the full deposit—is an automatic violation of the Maryland Home Improvement Law and grounds for license suspension.
2. Mandatory Written Contract Clauses
Every Maryland home improvement contract must be in writing, signed by all parties, and explicitly include:
- The contractor’s name, address, telephone number, and MHIC license number (MHIC number clearly displayed).
- The approximate dates when performance of the home improvement will begin and when it will be substantially completed.
- A clear description of the work to be performed and the principal materials to be used.
- The agreed total contract price, the initial deposit (not exceeding 1/3), and the schedule of progress payments.
- The statutory Maryland Home Improvement Guaranty Fund notice, the MHIC website/phone disclosure, and the homeowner’s Right to Cancel notice (3 business days—or 5 business days if the homeowner is 65 years of age or older—under the Maryland Door-to-Door Sales Act).
How do Maryland’s Home Improvement Guaranty Fund and penalties work in 2026–2027?
Every licensed MHIC contractor contributes to the Maryland Home Improvement Guaranty Fund, which compensates homeowners for actual monetary losses caused by an incomplete, defective, or abandoned residential contract up to $30,000 per claimant (with an aggregate cap per contractor unless reimbursed). If the Commission pays an award from the Guaranty Fund on your behalf, your MHIC license is suspended until you repay the Fund in full plus 10% annual interest.
How does Maryland’s 6% sales and use tax apply to contractors?
Under the Comptroller of Maryland’s Sales and Use Tax rules (Md. Code, Tax-Gen. § 11-101 and COMAR 03.06.01.19), Maryland treats real property contractors the same way whether they bill by lump sum or time-and-materials:
- Contractors pay 6% Maryland sales tax on all materials incorporated into real property at the time of purchase from the supply house (or self-assess 6% Maryland use tax on out-of-state purchases).
- Contractors do not charge the customer 6% sales tax on real property construction, remodeling, roofing, plumbing, electrical, or painting contracts.
- Exception for commercial janitorial and landscaping services: While building construction and repair labor are not taxable services, Maryland explicitly taxes certain commercial building cleaning/janitorial services and retail sales of tangible personal property that is not permanently annexed to realty.
Frequently asked questions
Is there a handyman exemption for small jobs in Maryland without an MHIC license?
No. Maryland has no dollar minimum exemption for residential home improvement work. Any person who contracts with a homeowner to repair, paint, remodel, or alter a 1-to-3 family residence must hold an active MHIC license regardless of whether the job is $150 or $50,000.
How much deposit can a contractor legally take in Maryland?
Under Md. Code, Bus. Reg. § 8-617, a Maryland contractor cannot receive or demand more than one-third (33.33%) of the contract price before or at the signing of a home improvement contract unless the contractor posts a full performance bond or irrevocable letter of credit covering the deposit.
Do contractors charge 6% sales tax to homeowners in Maryland?
No. On real property construction, remodeling, and repair contracts, the contractor is treated as the end user of the materials, pays 6% Maryland sales or use tax when buying supplies, and does not charge sales tax on the customer’s contract invoice.
How long is the homeowner cancellation period on a Maryland home improvement contract?
Under Maryland law, a homeowner has 3 business days after signing a home improvement contract to cancel without penalty, and that right extends to 5 business days if the homeowner is 65 years of age or older. The contract must include the written Notice of Cancellation form.
Does a Maryland plumber or electrician also need an MHIC license?
If a licensed Master Plumber, Master Electrician, or licensed HVACR contractor performs only work strictly within the scope of their state trade license, they are exempt from holding a separate MHIC license for that trade work. However, if they also contract to patch drywall, replace cabinets, lay tile, or remodel a bathroom beyond their trade license scope, they must also hold an MHIC license.
