It depends on whether you’re employed by the cable company or whether you’re working as an independent contractor, 1099, self-employed individual, or sole proprietor.
If you do contract work for a cable company, you likely qualify for a PPP loan. If you get a W2 from the cable company, you don’t qualify for a PPP loan for the money you made for that job. If you do other 1099/contract work on the side, however, your W2 job would not prevent you from getting approved for PPP funds from your contract work.
NOTE: Make sure you have a copy of your Schedule C (IRS Form 1040). The lender processing your PPP application will need this to verify your income.
