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

A solo handyman typically reports business income and expenses on Schedule C with Form 1040, pays self-employment tax on the profit, and makes quarterly estimated payments. The biggest wins come from tracking mileage, tools, materials and software all year. This guide is general information, not tax advice, so confirm figures with a CPA or irs.gov.

You are probably filing a Schedule C

If you operate as a sole proprietor or single-member LLC, you file Form 1040 with Schedule C. It asks three things:

1. How much did the business bring in? (gross revenue)
2. What did it cost to earn that? (deductible expenses)
3. The difference is your net profit, which is what gets taxed.

On top of income tax, net profit is generally subject to self-employment tax, which covers the Social Security and Medicare contributions an employer would normally split with you. Check the current rate and wage base at irs.gov.

Set money aside

Because there is no employer withholding, set a percentage of every payment aside in a separate account. The right percentage depends on your income, filing status and state, so ask a CPA for a number. A simple worked example of the habit:

• You receive a $1,000 payment.
• Your CPA says to reserve 30% for taxes.
• You move $300 into a tax savings account the same day.

Deductions to track

Deductible expenses must be ordinary and necessary for your business and documented. Common categories for handymen:

Vehicle expenses

You can generally use either the standard mileage rate or actual expenses. Confirm the current year's standard mileage rate at irs.gov. To see the math, if the rate were R dollars per mile and you drove 10,000 business miles, the deduction would be 10,000 × R.

• Standard mileage method. Log each business mile and multiply by the IRS rate.
• Actual expense method. Track gas, insurance, repairs and depreciation and deduct the business-use share.

The IRS has rules about when you can switch methods, so ask your CPA before the first year you use a vehicle for business. Business miles include driving to a job site or the supply house. Commuting rules have exceptions, so ask a CPA about your situation.

Keep a log as you go. A log reconstructed from memory at tax time is weak evidence; a contemporaneous one is much stronger. HandyBook's Business plan includes automatic GPS mileage tracking.

Tools and equipment

Drills, saws, ladders and similar items are generally deductible. Depending on the rules in force, you may be able to deduct the full cost in the year of purchase (Section 179 or bonus depreciation) or spread it over several years. Rules and limits change, so ask your CPA which method fits your income this year. Record the date, item and amount, and keep the receipt.

Materials and supplies

Materials that end up on a customer's job are a cost of doing the work. Track every receipt and link it to the job if you can, so you also see profit per job. See track handyman expenses.

Insurance

Business insurance premiums, such as general liability, tools coverage and a business auto policy, are generally deductible. Health insurance for the self-employed has its own rules, so ask your CPA.

Phone and internet

The business-use share of your phone and internet is generally deductible. Pick a defensible percentage based on actual use and keep it consistent.

Home office

A home office generally needs a space used regularly and exclusively for business. The IRS offers a simplified method and a regular method. Check the current simplified-method rate and limit on irs.gov.

Software, marketing and professional fees

Field service software, accounting software, website hosting, advertising, business cards, and fees for your accountant or attorney are generally deductible business expenses.

Processing fees

Card-processing fees you pay are deductible. Add up the fees from your Stripe, Square or other statements at year end so you do not miss them. For how fees compare, see Stripe vs Square for handymen.

Continuing education

Trade classes, manufacturer training and certification renewals related to your business are generally deductible.

What you generally cannot deduct

• Personal use of your vehicle.
• Everyday clothing. Work boots or PPE may qualify; the jeans you wore to the job do not.
• Personal meals. Business meals have specific rules, so ask your CPA.
• Traffic tickets and parking fines.
• A salary to yourself as a sole proprietor. Your pay is the Schedule C profit.

Quarterly estimated taxes

The IRS expects tax to be paid through the year. If you expect to owe tax above the IRS threshold when you file, you generally need to make quarterly estimated payments. Confirm the current threshold, safe-harbor rules and due dates at irs.gov, because dates can shift when they fall on a weekend or holiday.

The mechanics:

1. Estimate your annual net profit.
2. Estimate federal income tax, self-employment tax and any state tax.
3. Divide by four, or use Form 1040-ES to compute each payment.

Missing payments can bring an underpayment penalty, so set a calendar reminder for each due date.

When to consider an S corporation

An S corporation election can change how much of your profit is subject to self-employment tax, in exchange for running payroll, a reasonable salary requirement and extra filings. Whether it pays off depends on your profit, state and costs. Do not guess a break-even number; ask a CPA to model it with your real figures before you switch.

A tracking system that works

1. A separate business bank account. Every business dollar in and out goes through it.
2. A receipt habit. Photograph each receipt the day you get it. HandyBook Pro includes receipt scanning (OCR).
3. A mileage log that updates as you go. An app or a notebook in the truck, daily.
4. A monthly check. Review profit and expenses once a month, not once a year.

A year-round tax calendar

Tax stress usually comes from doing everything in one weekend. Spread it out:

When	Task
Weekly	Photograph receipts, log mileage, mark paid invoices
Monthly	Reconcile your bank account, move your tax-reserve percentage into savings, review profit
Each quarter	Check estimated-tax due dates at irs.gov and make payments
Year end	Review equipment purchases with your CPA before December 31
January	Collect forms from clients and payers, total your expenses by category
Filing season	Hand your CPA a clean summary

Worked examples

All numbers below are illustrative round figures, not tax rates. Use them to learn the arithmetic, then replace them with figures from irs.gov and your CPA.

Net profit

• Gross revenue: $90,000
• Materials: $18,000
• Vehicle (mileage): $6,000
• Tools: $2,500
• Insurance: $2,400
• Software and phone: $1,800
• Other expenses: $1,300
• Total expenses: 18,000 + 6,000 + 2,500 + 2,400 + 1,800 + 1,300 = $32,000
• Net profit: 90,000 - 32,000 = $58,000

Every extra dollar of documented, legitimate deduction reduces this number, which is why records matter.

Mileage arithmetic

The deduction is business miles multiplied by the current IRS standard rate. If you drove 9,000 business miles and the rate were R dollars per mile, the deduction is 9,000 x R. Look up R for the tax year on irs.gov, then keep a log of date, start and end location, purpose and miles for every trip.

Setting aside a tax reserve

If your CPA tells you to reserve 28 percent of profit, then on a $2,500 payment you move 2,500 x 0.28 = $700 into the tax account. Do this the day the money lands. The percentage is your CPA's call, not a rule of thumb from a blog.

Home office, simplified method

The IRS simplified method multiplies square feet of qualifying office space by a set per-foot amount, subject to a maximum. Confirm the current amount and cap at irs.gov. If the rate were r dollars and your office is 100 square feet, the deduction is 100 x r.

What to hand your accountant

Use this checklist at the start of filing season:

• Profit and loss summary for the year
• Revenue by month
• Expenses by category, with receipts available
• Mileage log with total business miles
• List of equipment purchased, with dates and amounts
• Insurance premium totals
• Estimated tax payments made and dates
• Forms received from clients and payment platforms
• Details of any subcontractors you paid
• Prior-year return

Subcontractors raise their own rules, including information-return requirements when payments cross IRS thresholds. Confirm current thresholds and forms at irs.gov. HandyBook's Business plan lists 1099 prep as a feature. See subcontractor vs employee.

Copy-paste message for your CPA

Hi [Name], I am a self-employed handyman filing Schedule C. I would like to review (1) my estimated-tax plan for next year, (2) whether my vehicle method is right, (3) how to treat equipment purchases this year and (4) whether an entity change makes sense at my profit level. Can we book 30 minutes? I will send my profit and loss and mileage log first.

Common mistakes

• Mixing personal and business money. One account for business keeps records clean.
• Estimating mileage after the fact. Log it as you go.
• Forgetting small recurring costs. Software, phone and card fees add up over a year.
• Ignoring estimated taxes. Missed payments can bring penalties.
• Deducting personal items. If it is not ordinary and necessary for the business, leave it out.
• Skipping professional help. A CPA can cost less than the errors they catch.

FAQ

Do handymen file Schedule C?

Most sole proprietors and single-member LLC owners do, attached to Form 1040. Multi-member LLCs and corporations file differently, so confirm your structure with a CPA.

What can a handyman write off?

Common write-offs include vehicle costs, tools, materials, insurance, software, marketing, professional fees and card-processing fees. Each must be ordinary, necessary and documented.

How much should I set aside for taxes?

It depends on your profit, filing status and state. Ask a CPA for a percentage based on last year's return, then move that share of each payment into a tax account.

Do I have to pay quarterly estimated taxes?

Often yes if you expect to owe more than the IRS threshold. Check Form 1040-ES instructions and irs.gov for current thresholds and dates.

Should I hire an accountant?

For most handymen, yes, at least once a year. A CPA can confirm your deductions, entity choice and estimated payments for your state.
