Licensing

Delaware contractor license requirements

Delaware's contractor license is a business and tax license from the Division of Revenue, not a competency exam. Nonresident contractors also post a tax bond, and plumbers, HVACR contractors, and electricians are licensed separately by the Division of Professional Regulation.

Every contractor working in Delaware, general or subcontractor, resident or nonresident, must hold a contractor license from the Delaware Division of Revenue. It costs $75 a year and is issued under Title 30, Chapter 25 of the Delaware Code. There is no trade exam for it. The license is tied to taxes: contractors also pay a license fee on gross receipts, and out-of-state contractors post a surety bond on larger jobs. Skill-based licensing happens only for specific trades, mainly plumbing, HVACR, and electrical work, through the Division of Professional Regulation.

Who needs a Delaware contractor license

Section 2501 defines a contractor broadly. It covers anyone furnishing labor or labor and materials for all or any part of the construction, alteration, repair, dismantling, or demolition of buildings, roads, bridges, viaducts, sewers, water and gas mains, and every other type of structure. It does not matter whether you are the prime contractor or a sub, or whether your company is based in Delaware or across the line in Pennsylvania, Maryland, or New Jersey. Construction transportation contractors and real estate developers are included too.

Timing matters. Under section 2502, the license must be obtained, and proof of compliance made, before or at the time the contract is signed. On competitively bid contracts over $50,000, you must have started the license application before you submit the bid. A subcontractor must have started before the general contractor submits its bid. So if you are pricing a Delaware job in your estimating queue, start the license paperwork before bid day, not after award.

How to get the license

  1. Apply to the Division of Revenue. The contractor license application goes to the Division of Revenue, which also handles the gross receipts filings that follow.
  2. Line up workers' compensation. The Division of Revenue will not issue the license until you file a certificate of insurance showing workers' compensation coverage as required by Delaware law, or proof that the Department of Labor has approved you as a qualified self-insurer.
  3. File the Department of Labor notice. You must file a certificate of notice from the Delaware Department of Labor confirming you told the department you will be performing labor on a Delaware construction project.
  4. Post the nonresident bond if it applies. Out-of-state contractors must satisfy section 375 before the license issues.
  5. Pay the $75 fee. The license runs until January 1. Each renewal costs $75 plus the gross receipts fee owed.

The gross receipts license fee

This is where Delaware differs from almost every neighboring state. On top of the $75 license, every contractor pays a license fee of 0.6472% of aggregate gross receipts, due by the 20th of each month for the previous month, with a $100,000 deduction each month. Contractors whose taxable receipts during the lookback period stay at or under the threshold (written into the statute as $1,500,000 and adjusted annually) file quarterly instead, with a $300,000 quarterly deduction. Related entities under common ownership get only one deduction across the whole group.

General contractors can exclude money paid to subcontractors, but only if the sub is licensed under Chapter 25 and a written agreement states the exact sums payable. Say a general contractor collects $900,000 in a month on a school addition and pays a licensed drywall sub $180,000 under a written subcontract. That $180,000 comes out of the GC's gross receipts. If the drywall sub was unlicensed, or the deal was a handshake, the GC can lose the exclusion. Keeping executed subcontracts and each sub's Delaware license number in one file is a tax issue here, not just a paperwork habit.

Nonresident contractors and the 6% bond

Under 30 Del. C. section 375, a nonresident contractor or subcontractor must file a surety bond with the Department of Finance to guarantee payment of Delaware taxes and fees. The bond is 6% of the contract price on any contract of $20,000 or more, or 6% of estimated cost and profit on a cost-plus contract of that size. When two or more contracts in one calendar year add up to $20,000 or more, the bond covers 6% of the aggregate. The bond must be filed before construction begins. The Division of Revenue can accept cash bonds instead, and the Secretary of Finance can waive the bond in whole or in part. Nonresidents must also notify the department within 20 days after completing each Delaware project.

Delaware also puts a duty on the people who hire nonresidents. Section 2503 requires architects, engineers, contractors, and construction managers to report each contract with a nonresident contractor or sub within 10 days, with the contract value and the parties' names and addresses. Failing to do it can bring a civil penalty of up to $10,000 per occurrence.

Plumbing, HVACR, and electrical licenses

The Division of Professional Regulation handles trade competency. The Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners issues master plumber, master HVACR, and master restricted HVACR licenses; a restricted license limits practice to a specialty such as air conditioning. Its fee schedule lists the application fee at $173 for each of those three. The Board of Electrical Examiners licenses apprentices, residential electricians, journeypersons, master and limited electricians, and master and limited special electricians whose work is restricted to specialties such as elevators or HVAC. All applications go through the DELPROS system, and the boards review only complete applications at their monthly meetings. Local building departments may add their own permit and registration steps, so check with the town or county before work starts.

Delaware contractor license lookup

To confirm a business holds a current Division of Revenue license, use the Business License Search on revenue.delaware.gov and filter by business activity for contractor; results show the license number and valid dates. For a plumber, HVACR contractor, or electrician, use the DELPROS license verification at delpros.delaware.gov, which DPR treats as primary source verification. Public jobs bring their own rules, so also review Delaware prevailing wage requirements and Delaware mechanics lien deadlines.
