Do plumbers pay self-employment tax?
If you earn as an independent contractor, yes — self-employment tax is 15.3% (Social Security and Medicare) on your net profit, on top of regular income tax. You deduct half of it, and every business deduction lowers what you owe. We handle the calculation on Schedule SE.
What can plumbers write off?
Common write-offs include pipe wrenches, augers, and specialty plumbing tools, pipe, fittings, fixtures, and materials for jobs, service van expenses (actual costs or standard mileage), state plumbing license and continuing education, plus a share of your phone and any home-office use. We go through your year line by line so nothing legitimate gets missed.
Do plumbers need to pay quarterly estimated taxes?
If you expect to owe $1,000 or more for the year, the IRS generally wants quarterly estimated payments to avoid an underpayment penalty. We calculate them so next April isn't a surprise.
Do I have to report income if I didn't get a 1099?
Yes. Your income is taxable whether or not a client or platform sent a 1099. We report it correctly and offset it with every deduction you qualify for.
