Handyman Business Taxes — What to Track (and Deduct) in 2026

Disclaimer up front: I'm not a CPA. This is a working handyman's guide to the categories that actually matter, written so you'll know what to ask your accountant. For your own filing, hire one. A good accountant costs $400–$900 a year and finds at least that much in deductions you'd miss.

Most solo handymen don't lose money to bad bookkeeping. They lose money to forgotten deductions — the $4,800 in mileage they didn't log, the $1,200 in tools they paid cash for and threw the receipts away, the home office they didn't realize qualified. Tax planning isn't about being aggressive. It's about not leaving real money on the table.

Here's the working-handyman version of what to track in 2026.

You're filing a Schedule C

If you're a solo handyman operating as a sole proprietor or single-member LLC, you file Form 1040 with a Schedule C attached. Schedule C is where your business income and expenses go.

A Schedule C asks:

1. How much did the business make? (gross revenue)
2. How much did it cost to make that money? (deductible expenses)
3. The difference is your business profit, which becomes your taxable income.

On top of income tax, you also pay self-employment tax (15.3%) on that profit — that's the Social Security and Medicare portion that an employer would normally split with you. Self-employment tax is why "I made $80,000 this year" doesn't mean you take home $80,000.

Plan for roughly 25–30% of your profit going to taxes if you're a solo handyman in a no-state-income-tax state. Add 4–9% on top in states like California, New York, or Oregon. That's a rough rule, not a precise one — your situation will vary.

The deductions that move the needle

In rough order of how much they save the average solo handyman:

Vehicle expenses (mileage)

This is the single biggest deduction most handymen miss. The 2026 IRS standard mileage rate is around $0.70/mile (it adjusts each year). If you drove 18,000 business miles, that's a $12,600 deduction. At a 25% effective rate, that's $3,150 back in your pocket.

You can either:

• Standard mileage method. Track every business mile, multiply by the IRS rate. Simpler. Works best if your vehicle is reliable and not expensive to operate.
• Actual expense method. Track gas, insurance, repairs, depreciation, and deduct the business-use percentage. More work. Works better if you bought a new truck for the business.

Pick one method the first year you use the vehicle for business. Once you choose actual, you generally can't switch back. Most solo handymen use standard mileage and never look back.

What counts as a business mile: driving to a job, to the supply house, to the bank to deposit a check. What doesn't: your commute to a "first" location, personal errands.

Track this daily, not yearly. A mileage log reconstructed in April from memory will not survive an audit. A log written in real time (or pulled from an app like HandyBook, MileIQ, or Google Maps Timeline) will.

Tools and equipment

Anything you bought to do the work. Drills, saws, ladders, tile cutters, pressure washers, a generator, work lights. Vehicle accessories (ladder racks, toolbox, bed liner).

In 2026, you can usually expense these in full the year you buy them under Section 179 or bonus depreciation. Talk to your accountant about which method to use — sometimes spreading the deduction over multiple years saves more if you expect higher income next year.

Track:

• Date purchased
• What it was
• Amount

Snap the receipt and store it. Don't trust your memory for $87 at Home Depot in February.

Materials and supplies (cost of goods sold)

Anything you bought that ended up on a customer's property — tile, paint, faucets, lumber, screws, wire nuts. These are 100% deductible.

Track every supply-house and Home Depot receipt. If it's billable to a specific job, link it to the job in your software so you can also see your true profit per job (not just gross revenue).

Insurance premiums

General liability, tools coverage, surety bond, business auto policy. All deductible. Health insurance premiums for yourself are deductible above-the-line if you don't have access to a spouse's plan.

Phone and internet

The business-use percentage of your cell phone bill and home internet is deductible. Most handymen land at 60–80% business use. Pick a defensible number and stick with it.

Home office

If you have a space in your home used regularly and exclusively for business — even a small desk and filing cabinet in a spare room — you can deduct the home office.

Two methods:

• Simplified method. $5/sq ft, up to 300 sq ft. Max $1,500. Less paperwork.
• Actual method. Calculate the business-use percentage of your home (office sq ft ÷ total sq ft), apply that to rent/mortgage interest, utilities, insurance, depreciation. Bigger deduction, more work.

The "exclusive use" part is real. A dining room table where you also eat dinner doesn't count. A converted closet that holds your laptop and printer does.

Software, subscriptions, marketing

Field service software (HandyBook at $19/mo = $228/yr, fully deductible), QuickBooks, your website hosting, Google Ads, Nextdoor Pro, Yelp ads, business cards, vehicle wraps. All deductible.

Continuing education

Trade school classes, manufacturer training, OSHA certification renewals, books and courses related to the business. Deductible.

Professional fees

Your accountant. Your business attorney. Anyone you pay to keep the business running properly.

Bank and processing fees

Business bank account fees, Stripe/Square/HandyBook POS processing fees. The card-processing fees alone usually run 2–3% of card revenue — on $120,000 in card sales, that's $2,400–$3,600 in deductions you might forget about.

What you can't deduct (and shouldn't try to)

• The full cost of personal vehicle use.
• Clothing that isn't a uniform or PPE. Steel-toe boots — yes. The jeans you wore to the job — no.
• Meals you ate alone on the job. Business meals with clients or for travel are partially deductible; lunch you grabbed because you were busy is not.
• Traffic tickets and parking fines.
• Your own salary as a sole prop. (Your "pay" is the profit on Schedule C.)

Trying to deduct things that don't qualify is how you fail an audit. The good stuff is enough.

Quarterly estimated taxes

The IRS expects you to pay taxes as you earn them, not in one lump in April. If you owe more than $1,000 in tax at year-end, you generally need to pay quarterly estimates: April 15, June 15, September 15, January 15.

Skip them and you owe an underpayment penalty (small, but annoying). The mechanics:

1. Estimate your annual profit.
2. Calculate the tax on that profit (federal income tax + self-employment tax + state, if any).
3. Divide by four. That's your quarterly payment.

Easy rule of thumb: set aside 25–30% of every payment you receive in a separate "tax" savings account. When April rolls around, you'll have the money. Most handymen who get into tax trouble didn't fail to earn — they failed to set aside.

When to consider incorporating

Most solo handymen do fine as a sole prop or single-member LLC for years. The conversation about S-corp election usually starts when you're consistently netting $50,000–$70,000+ in business profit.

The S-corp pitch in one paragraph: you pay yourself a "reasonable salary" through payroll, and the rest of the profit flows through as distributions that don't get hit with the 15.3% self-employment tax. On $80,000 of profit, that can save $5,000–$8,000 a year — minus the cost of payroll software and tax prep ($1,500–$2,500/yr) and the extra paperwork (separate tax return, quarterly payroll filings).

The math works for some people and doesn't for others. Have a 30-minute conversation with a CPA before you make the change. If your profit is under $50k, it's almost never worth it. If your profit is over $100k, it almost always is.

The tracking system that actually works

You don't need anything fancy. You need three things that stay current:

1. A real business bank account. Not your personal account with a memo line. Every business dollar in, every business dollar out, through one account. This single change makes your tax prep faster, your audit safer, and your accountant happier.
2. A receipt habit. Photograph every receipt the day you get it. Throw the paper away if you want. The image is the record.
3. A mileage log that updates itself. Either an app or a notebook in the truck. Daily, not monthly.

That's the whole system. Anything beyond that is optimization.

How HandyBook helps (and where you still need an accountant)

HandyBook tracks invoices, expenses, mileage, and card-processing fees in one place and exports a clean year-end summary that your accountant can drop straight into your Schedule C. It does not file your taxes. It does not replace an accountant. What it does is make sure the data your accountant needs is sitting in one place when April comes, instead of in three apps, a shoebox, and your memory.

Want to start the year right? The 14-day free trial takes about 10 minutes to set up. Add your bank account, snap a few receipts, and watch the categories build themselves. The features page walks through how the year-end export works. Either way, find a CPA you trust before next January. Your accountant is the cheapest insurance policy a small business buys.
