As a welder, you’ll primarily interact with the Internal Revenue Service (IRS) for tax obligations and the Federal Trade Commission (FTC) for advertising compliance. You may also need to report beneficial ownership information to FinCEN.
Currently, the U.S. Small Business Administration indicates that no industry-specific federal license is required to operate a welding business. However, you still need to comply with federal regulations regarding taxes and advertising.
Costs vary significantly; IRS fees depend on your tax liability, while FTC compliance is generally free, though legal counsel may incur costs. The Annual BOI Reporting Requirement with FinCEN also has associated fees.
The Corporate Transparency Act requires many companies, including LLCs, to report information about their beneficial owners to FinCEN. This is to prevent financial crimes, and failure to comply can result in penalties.
Federal income and self-employment taxes are generally filed annually with the IRS, though estimated taxes may be required quarterly depending on your income. Record retention requirements are ongoing, and the BOI report is filed initially and updated as needed.
