Frequently asked questions
- What is NAICS 221116?
- NAICS 221116 is the North American Industry Classification System code for Geothermal Electric Power Generation. It classifies this business activity for statistical, regulatory, and government procurement purposes. Federal agencies use NAICS codes to collect and publish data about the US economy, determine SBA size standards, and set aside contracts for small businesses.
- What licenses and permits does a Geothermal Electric Power Generation need?
- A Geothermal Electric Power Generation typically needs a local business license, a federal EIN from the IRS, and industry-specific permits depending on the sector. Check with your city or county clerk for a general business license, your state's professional or industry licensing board for any required occupational licenses, and your state's tax authority for a sales tax permit if you sell taxable goods or services.
- How do I register a Geothermal Electric Power Generation business in the United States?
- To register a Geothermal Electric Power Generation business, first choose your legal structure: sole proprietorship (simplest, uses SSN), LLC (personal liability protection, files with your Secretary of State), or corporation (Form 1120 or 1120-S). Register your business name (DBA) with your county if operating under a trade name. Obtain an EIN from the IRS at irs.gov/ein. Register with your state revenue department for any applicable taxes.
- What tax forms does a Geothermal Electric Power Generation file with the IRS?
- Tax forms depend on your entity type. A sole proprietor files Schedule C with Form 1040 and Schedule SE for self-employment tax (15.3%). An LLC taxed as a partnership files Form 1065 with Schedule K-1s. A C-Corporation files Form 1120 (21% flat rate). An S-Corporation files Form 1120-S. All businesses paying employees file Form 940 (FUTA) annually and Form 941 quarterly. Estimated tax payments are made via Form 1040-ES four times per year.
- Is Geothermal Electric Power Generation the right NAICS code for my business?
- Your NAICS code should reflect your primary business activity — the one generating the most revenue or value. If Geothermal Electric Power Generation describes your main line of business, NAICS 221116 is likely correct. If you have multiple distinct activities, you may need separate codes for statistical reporting. For federal contracting, your SAM.gov registration should use the code that best matches the work you perform. Review the official NAICS 221116 description and exclusions to confirm it fits your operations.
- What EPA lead-safe certification does a Geothermal Electric Power Generation need?
- Under the EPA Renovation, Repair and Painting (RRP) Rule, contractors working on pre-1978 homes or child-occupied facilities where lead paint may be disturbed must be EPA Lead-Safe Certified. This requires an 8-hour initial training course from an EPA-accredited provider, firm certification ($300 fee to EPA), and lead-safe work practices (containment, HEPA vacuuming). Recertification is required every 5 years. Violations carry fines up to $41,000 per day.
- Does a Geothermal Electric Power Generation need a contractor license in multiple states?
- Contractor licenses are state-specific with limited reciprocity. Many states have partial reciprocity agreements recognizing the exam portion of the license from another state, but you'll still need to apply, pay fees, and may need to pass the state-specific business/law portion. Some states (notably California, Florida, and Arizona) have strict licensing requirements with no reciprocity. Always check the target state's contractor licensing board before performing work across state lines.
- What are prevailing wage (Davis-Bacon) requirements for a Geothermal Electric Power Generation?
- The Davis-Bacon Act requires payment of locally prevailing wages and fringe benefits on federal construction contracts exceeding $2,000. Similar state-level prevailing wage laws (Little Davis-Bacon) apply to state-funded projects in about 32 states. Contractors must submit certified payroll reports (Form WH-347) weekly listing each worker's classification, hours, rate, and fringe benefits. Willful violations can result in debarment from federal contracts for up to 3 years.
- What contractor license does a Geothermal Electric Power Generation need?
- Most states require a general contractor license for projects above a dollar threshold (typically $500-$50,000 depending on the state). Requirements include passing a trade and business/law exam, documenting 2-5 years of experience, providing a surety bond ($5,000-$100,000+), and carrying general liability insurance. Electrical, plumbing, and HVAC require separate specialty licenses in virtually all states with additional trade-specific exams.
