Life as a lab tech can feel like being stuck running on an endless wheel — an expensive endless wheel. But if you work as an independent contractor, there's good news. Every work-related purchase you make, from testing supplies to data analysis software and more, can actually save you money on your taxes.
Writing off those expenses at the end of the year lowers your taxable income, reducing how much you need to pay. It’s like raising the boiling point of your taxes, so your hard-earned money doesn’t turn to steam and float away!
The lab coat you wear at work — and any cleaning or alteration services for it — are deductible.
Write off the protective gear, like goggles and gloves, you wear on the job.
Write off any subscriptions or licensing fees you pay for analytics platforms.
Any chemicals, tools, or equipment you use to run lab tests can be deducted.
Consumables — petri dishes, reagents, chemicals, single-use testing supplies — are deductible here. Durable equipment like microscopes, centrifuges and analyzers is depreciated on Box 13.
Classes you take to enhance your skills after getting your license are tax write-offs.
This covers training that maintains or improves skills for the work you already do. Courses that qualify you for a new trade or profession are not deductible.
Any required certifications or licensing fees can be deducted.
Protecting yourself and your business with liability insurance? It's a write-off.
Disposing of solvents, biohazard or medical waste the way your work requires is a write-off.
Bubble mailers, boxes, tissue paper and more: anything you buy to ship customer orders is a write-off.
Certifications and compliance fees your field requires to keep operating are deductible.
If you drive for work ...
If you use a vehicle for things like picking up lab supplies or traveling between labs, you can deduct your car expenses. But remember, you can only write off the percentage of expenses related to your job.
Parking for a meeting downtown, or any other work trip, is tax-deductible!
A toll while driving to or from a work destination is tax-deductible!
If you buy a new car, you can write off part of the cost every year for five years.
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 ...
Meal expenses can be deducted on your tax return if they're work-related. For example, if you talk shop with a fellow lab technician, researcher, or scientist over lunch, the cost is deductible.
If you discuss work with a coworker, mentor, client, or prospective client, it's a write-off — 50% of the tab.
If you leave town for work ...
Whether you get from point A to B on a business trip by rental car, train, bus, or plane, you can deduct travel expenses. That applies for any kind of out-of-town conference or seminar you might attend.
Planes, trains, and car rentals are all work-related travel costs that can be written off.
When you travel for work, lodging expenses such as hotel rooms or Airbnb are write-offs.
When you're traveling for work, your meals are 50% deductible — takeout included. (Long-haul truck drivers subject to DOT hours-of-service rules can deduct 80%.)
If you work from home ...
Home office expenses, like internet and heat, can be written off if you work from home on things like industry research or studying up in your field.
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.
Repairs just for your home office are 100% deductible. Repairs to the rest of your home count too, prorated by your business-use percentage on Form 8829.
Gotta keep the lights on in your home office! A portion of your electricity bill counts.
Whether it's rental or homeowners insurance, you can write off a portion through your home office deduction.
It'd be hard to work in an office without running water, huh? Your water bill counts.
You need internet to do your job! If you claim a home office, deduct it prorated on Form 8829 along with your other utilities. Internet you pay for on the road, purely for work, is 100% deductible.
