Let me tell you about the year I paid $3,200 more in taxes than I needed to. It was my third year in business and I was keeping track of materials on jobs pretty well, but that was about it. My accountant asked for my expense records and I handed her a shoebox with maybe half my receipts and a spreadsheet that stopped being updated in June. She did the best she could, but there was easily $12,000-$15,000 in deductible expenses I couldn't prove. At a roughly 25% effective tax rate, that's real money I just gave away.
The Expenses You Are Probably Forgetting
Most handymen track the obvious stuff: materials you buy for a specific job. But that is the tip of the iceberg. Here is what I see guys miss constantly:
- Fuel and mileage: You are driving 50-100 miles a day between jobs, the supply house, and home. At the current IRS mileage rate of $0.70 per mile, that is $35-$70 a day. Over 250 working days, we are talking $8,750-$17,500 in deductions. Are you tracking your mileage? Most handymen are not.
- Tools and equipment: That new impact driver, the replacement saw blade set, the socket set you bought because your 10mm disappeared into another dimension. It adds up to $1,500-$3,000 a year for most guys.
- Insurance premiums: General liability, vehicle insurance (business portion), workers comp if you have employees. These are fully deductible and they are not cheap.
- Phone bill: If you use your phone for business — and you do — at least 50-75% of that bill is deductible. That is $600-$900 a year most people skip.
- Subscriptions and software: Accounting software, scheduling apps, cloud storage for job photos. Small amounts that add up fast.
- Work clothing and safety gear: Steel-toe boots, work pants, company shirts, hard hats, safety glasses. If you would not wear it to dinner, it is probably deductible.
What Untracked Expenses Actually Cost You
Let us do some quick math. Say you are missing $10,000 in legitimate deductions because you did not track them. At a 25% tax rate, that is $2,500 straight out of your pocket. At 30%, it is $3,000. Every single year. For many handymen, that is a nice vacation, a major tool upgrade, or a month of truck payments. And it is money you earned — you just could not prove the expenses to offset it.
The IRS does not care that you "definitely bought gas that day." They want a receipt or a log. No documentation, no deduction. It is that simple and that harsh. I had a buddy get audited two years ago and he lost $7,400 in deductions because he had no receipts for his supply house runs. He knew he spent the money. The IRS did not care.
Receipt Management Without Losing Your Mind
I am not going to pretend I enjoy keeping receipts. Nobody does. But here is what actually works: take a photo of every receipt the moment you get it. Standing at the register at Home Depot? Snap a picture before the receipt goes in your pocket where it will become an unreadable wad of thermal paper in three days.
Use any app that lets you photograph and categorize receipts. It does not have to be fancy. The key is doing it immediately, not "later tonight." Later tonight never happens. You will be tired, you will forget, and that receipt will vanish into the black hole that is your center console. I have been doing the instant-photo method for four years now and I have not lost a deduction since.
Pro tip: set up a dedicated email address and forward digital receipts there too. Online orders from Amazon, supply house e-receipts, insurance payment confirmations — they all go to one place instead of getting buried in your regular inbox.
Mileage: The Biggest Missed Deduction
If you are not tracking mileage, you are almost certainly leaving the biggest deduction on the table. The IRS gives you two options: actual vehicle expenses (gas, maintenance, depreciation, insurance) or the standard mileage rate. For most handymen, the standard mileage rate is simpler and often more generous.
You need a log that shows: date, starting location, destination, purpose, and miles driven. Every business trip, every day. There are apps that do this automatically using your phone's GPS — you start driving and it records. At the end of the year, you export a report. It takes literally zero daily effort once it is set up.
One of my buddies started tracking his mileage properly last year after I nagged him about it for months. He logged 22,000 business miles. At $0.70 per mile, that was $15,400 in deductions he had been missing every single year. His face when his accountant told him what he had been leaving on the table was something else.
Categorize as You Go
Do not dump everything into one "business expenses" bucket and sort it out at tax time. You will not sort it out at tax time. You will guess, and you will guess wrong, and your accountant will charge you extra for the mess. Set up basic categories and assign every expense as it happens: materials, fuel, tools, insurance, vehicle maintenance, office supplies, advertising, meals with clients.
When you track expenses by category, patterns jump out. I realized I was spending $400 a month at Home Depot on stuff that was not for specific jobs — replacement blades, fasteners, tape, caulk, all the consumables. Once I saw that number, I started buying in bulk from a contractor supply house and cut it to $250. You cannot optimize what you cannot see.
Start Today, Not January 1st
The best time to start tracking expenses was when you started your business. The second best time is right now. Do not wait for the new year, do not wait for Monday, do not wait until you "have time to set up a system." Open HandyBook, snap a photo of your next receipt, and keep going from there. The app categorizes expenses automatically and generates reports your accountant can actually use. Future you — especially April 15th you — will be very grateful.
