As a self-employed ironworker, you spend your days on physically demanding, often dangerous job sites. It’s understandable why you might not want to spend much time on things like taxes once you come home. So let’s keep things simple: Did you know that, as a contract ironworker, you can write off the business expenses you encounter every day at your job sites?
Whether it’s protective gear or equipment repairs, you know how well these ordinary expenses add up. Don’t let the IRS take more of your money than you have to. Claim the following write-offs for ironworkers, and keep more of your hard-earned money for yourself this year.
Solder, welding rods and wire, and small hand tools are deductible supplies. Welding machines and other big-ticket equipment are depreciated on Box 13.
Write off the protective gear, like goggles and gloves, you wear on the job.
Freelancers, contractors, or other services that help you run your business are tax-deductible.

Any required certifications or licensing fees can be deducted.
Fees to renew your license to perform your work are fully deductible.
If you drive for work ...
The IRS allows people who drive for work to claim vehicle expenses on their taxes. So if you drive to meet a client or pick up ironworking tools, go ahead and add those write-offs to your Schedule C.

Flashlights, tire iron, duct tape, and other tools you may need in your vehicle are deductible.
Car insurance monthly fees, registration, even roadside assistance are partially deductible — if you use the actual expense method. The standard mileage rate already covers them.
Oil changes, repairs, and regular checkups are deductible if you use the actual expense method. Take the standard mileage rate instead and they're already baked into your per-mile deduction.
If you discuss work at a restaurant ...
Grabbing food or coffee with fellow mentors or clients is tax-deductible as long as the purpose of the meeting is to talk about work.
What about the cost of buying snacks to munch on while at work? Unless you're required to eat for your job, this, unfortunately, doesn't count.
If you discuss work with a coworker, mentor, client, or prospective client, it's a write-off — 50% of the tab.

If you work from home ...
Working on client development or conducting industry research are some tasks an ironworker might take care of from a dedicated at-home workstation.
In this case, you can claim home office deductions on your taxes.
A desk, chairs, lamps, and other home office necessities are all tax write-offs. Anything over about $2,500 gets depreciated on Form 4562 instead of written off all at once.
