Frequently Asked Questions

What is the Annual BOI Reporting Requirement?

Does the FTC regulate my welding business?

Yes, the Federal Trade Commission’s Truth-in-Advertising and Consumer Protection Rules apply to all businesses, including welding services. These rules ensure fair and accurate advertising and protect consumers from deceptive practices.

What does it mean to have 'Federal Income and Self-Employment Tax Obligations'?

As a welder operating as an LLC, you are responsible for paying both income tax on your profits and self-employment tax, which covers Social Security and Medicare. The IRS fee varies based on your income and deductions.

Is an EIN always required for a welding business?

Yes, even if you don’t plan to hire employees, the IRS generally requires you to obtain an EIN for your LLC. This serves as your business’s tax identification number and is free to obtain, though associated professional fees may apply.

What kind of records should I keep for the IRS?

You should keep records of all income and expenses, invoices, receipts, and tax returns for at least three years, and potentially longer depending on the situation. Proper recordkeeping is essential for accurate tax filing and to support any claims made on your tax return.
