Every year we take on new clients who are leaving real money on the table — not because they're doing anything wrong, but because nobody has ever walked them through what's actually available to a home service business owner. The tax code isn't short on deductions for plumbers, electricians, HVAC contractors, roofers, and landscapers. What's short is the attention most generalist accountants give to finding them.
Below are the six categories we see underused most often. None of these are aggressive — they're plain, documentable, well-established deductions that a properly-kept set of books should already be surfacing.
1. Vehicle costs
If you drive to jobs, haul materials, or move crew between sites, you have a vehicle deduction waiting for you. The two methods — standard mileage and actual expenses — produce very different numbers depending on the vehicle and how you use it. Heavy service vehicles (over 6,000 lbs GVWR) often do significantly better under actual expenses plus Section 179. Light passenger vehicles almost always do better under standard mileage.
2. Equipment and tools
Under Section 179 and bonus depreciation rules, most equipment you buy for the business can be expensed immediately — not spread out over five or seven years. That includes trucks, trailers, compressors, diagnostic tools, ladders, even tablets and software subscriptions. The catch: the item has to be placed in service by December 31 of the year you're claiming it.
3. Home office
If part of your home is used regularly and exclusively for business — scheduling, invoicing, storing records, receiving customer calls — you have a home office deduction. The simplified method ($5/sq ft up to 300 sq ft) is easy and safe. The actual-expense method requires more work but usually produces a bigger deduction for owners with meaningful home office space.
4. Contractor payments
Every dollar you pay a legitimate 1099 contractor is deductible — but you have to issue 1099-NEC forms by January 31 if you paid them $600 or more during the year. Miss the deadline and the penalties stack fast. We run a clean W-9 collection process in December so there are no surprises at filing.
5. Continuing education and licensing
Trade license renewals, CE courses, safety certifications, industry conferences, subscriptions to technical publications — all deductible. So is the cost to maintain existing credentials or expand them into adjacent trades (an HVAC tech getting a refrigeration cert, for example).
6. Retirement contributions
A SEP IRA or Solo 401(k) can knock tens of thousands off your taxable income in a good year — and that money is yours. This is the single biggest deduction most owners overlook because it requires proactive planning before year-end. If you wait until April to think about it, you've already missed most of the benefit.
“The goal isn't to be aggressive. It's to make sure you're capturing what you're actually owed — and doing it in a way that stands up to scrutiny.”
Where to start
If any of this sounds unfamiliar, that's a sign your current setup isn't working for you. A proper year-end review takes an hour and usually turns up meaningful savings. We're happy to do that review — it's free, and if we can't find anything, we'll tell you that too.
