When you work as an independent 1099 examiner, the office you conduct exams in and the tools you use are part of running your practice, and their costs are usually deductible. This is a plain guide to the write offs providers most often miss, from the office itself to your equipment, mileage, and supplies, along with the simple records that make each one easy to defend.
The deductions most examiners leave on the table
When you work as an independent 1099 examiner, the office you conduct exams in and the tools you use are part of running your practice. The tax code lets you deduct the ordinary and necessary costs of doing that work, and for most examiners those costs are larger than they realize. The rule of thumb is simple. If you paid for something because of your work, and it is a normal cost for the kind of work you do, it is usually deductible. The rest of this guide walks through the categories that come up most often, along with the records that make each one easy to defend. One note before we start. This is general guidance, not tax advice for your specific situation. Rules change and details matter, so confirm anything meaningful with a qualified tax professional before you file.
The office you conduct exams in
The space where you see claimants and conduct C&P exams is a core cost of your practice, and how you deduct it depends on whether you rent or own. If you rent or lease the office, it is straightforward. The rent you pay for space used for your work is fully deductible. So are the costs that come with occupying it, such as utilities, internet at the office, cleaning, and any renters insurance or liability coverage tied to the space. If you pay for exam room furnishings, a waiting area, or signage, those count too. If you own the office property, the deduction works differently but is often larger. You can deduct the mortgage interest on the loan, the property taxes, insurance, utilities, and repairs and maintenance. On top of that, you generally depreciate the building itself over time, which spreads a portion of the purchase cost across each year you use it for business. Land is not depreciable, only the building. Because owned property brings in depreciation and the interest deduction, this is an area where a tax professional earns their fee, so treat the worksheet as your organized starting point rather than the final word. Two habits make either situation clean. Keep the lease or the loan and property tax statements with your records, and if any part of the space is used for something other than your exam work, deduct only the business share.
Internet and phone
Your internet connection and your phone are often mixed use, part work and part personal, so you deduct the business share, not the whole bill. Internet service at the office itself is generally fully deductible as an office cost. For a phone or a home connection you also use personally, estimate the percentage you use for work and apply that to the annual cost. If you use a line forty percent of the time for scheduling, records, and coordination, then forty percent of the bill is deductible. A phone line or connection kept only for work is fully deductible. Pick a reasonable percentage, write down how you arrived at it, and stay consistent.
Computer and equipment
The computer, monitor, printer, scanner, webcam, exam room equipment, and office furniture you buy for your work are deductible. For most examiners the full cost of these items can be written off in the year you buy them, rather than spread out over several years, thanks to first year expensing rules that remain generous. If an item is used partly for personal reasons, you deduct only the business use percentage. Keep the receipt and note what the item is used for, and if it is mixed use, note the split.
Mileage and work travel
If you travel between exam sites or drive to locations for your work, those business miles are deductible, either at the standard mileage rate or through your actual vehicle costs. Parking, tolls, and the cost of lodging and travel for out of town work count as well. The one line to watch is commuting. Driving from home to a regular office is treated as a personal commute and is not deductible, so keep a simple mileage log that separates true business trips from the daily drive.
Supplies and smaller costs
The small things add up. Paper, ink, folders, postage, medical and exam supplies, a shredder, cleaning supplies for the office, and software subscriptions you use for the work all count. So do professional costs that are easy to forget, such as license and credentialing fees, malpractice or liability insurance, continuing education, professional association dues, and the business share of your cell phone. Two of the largest deductions available to a 1099 provider often sit outside these everyday categories. A retirement plan such as a SEP IRA or a Solo 401(k), and self employed health insurance premiums, can each reduce your taxable income meaningfully. The amounts depend on your situation, so put them on the list of things to raise with your tax professional.
The record that makes all of this easy
Deductions are only as good as the records behind them. You do not need anything fancy. You need to capture the date, the amount, what it was, and which category it belongs to, and you need to do it as the year goes rather than reconstructing it in April. A simple worksheet or spreadsheet is enough. For mixed use items like a personal phone, the extra habit is writing down the business percentage and a one line reason for it. That single note is what turns a guess into a defensible number.
The takeaway
Your office, your internet and phone, your equipment, and your supplies are ordinary costs of running an independent practice, and they are deductible when you keep honest records and apply a reasonable business use percentage to anything mixed.
