Generally speaking, general contractors make between 6% to 12% profit. This means if a construction manager completes a $1M project, they can expect to make between $60,000 and $120,000 in profit. Residential subcontractors, on the other hand, usually make between 20% to 30% profit.
All contractors, including self-employed contractors and sole proprietorships, subcontractors and independent contractors, and corporations, partnerships and all other types of business entities must be registered, unless they fall into the two exemptions above.
Contractors in Pennsylvania need a license to remain on file with state records and to ensure that contractors meet minimum skills and knowledge thresholds to provide safe, high-quality services.
As an independent contractor, you must also withhold the standard federal self-employment taxes for Social Security and Medicare. The current self-employment tax rate is 15.3%, which consists of two parts: 12.4% for Social Security, including old-age, survivors, and disability insurance.
The law exempts from the registration requirements contractors who perform less than $5,000 worth of home improvements in a calendar year.
