Contractor tax deductions

Contractors often have more deductible business expenses than regular employees.

If you are self-employed, operate an LLC, work as an independent contractor, or run a construction business, you may be able to deduct ordinary and necessary business expenses related to your work.

Common contractor tax deductions include:

  • Tools and equipment
  • Vehicle expenses
  • Mileage
  • General liability insurance
  • Workers’ compensation insurance
  • Contractor license fees
  • Bond premiums
  • Home office expenses
  • Phone and internet
  • Software
  • Subcontractor payments
  • Materials and supplies
  • Advertising
  • Training and education
  • Professional fees
  • Depreciation

This guide explains the major categories.

For broader business tax planning, see the Business & Self-Employment Tax Guide.

Important tax rule

A business expense generally needs to be ordinary and necessary for your business.

For contractors, that usually means the expense is common, helpful, and directly related to earning business income.

Personal expenses are not deductible.

If an expense is partly business and partly personal, only the business portion may be deductible.

Contractor license fees

Contractor license and registration fees may be deductible as business expenses if they are required for your trade or business.

This may include:

  • State contractor license fee
  • Contractor registration fee
  • Local contractor registration
  • Business license fee
  • Renewal fee
  • Permit registration fee
  • Exam-related business licensing costs

If you are planning your licensing budget, use the General Contractor License Cost Calculator.

Contractor bond premiums

If a contractor bond is required for your business, the bond premium may be a deductible business expense.

Remember: the bond amount is not the same as the premium.

Example:

  • Required bond amount: $25,000
  • Premium paid: $625
  • Potential business expense: $625

Insurance

Contractor insurance premiums are often deductible business expenses.

This may include:

  • General liability insurance
  • Workers’ compensation insurance
  • Commercial auto insurance
  • Tools and equipment coverage
  • Builder’s risk insurance
  • Umbrella liability
  • Professional liability

Insurance must be related to the business.

Personal insurance is generally not deductible as a business expense.

Tools and equipment

Tools and equipment are major contractor deductions.

Examples include:

  • Drills
  • Saws
  • Ladders
  • Compressors
  • Generators
  • Measuring tools
  • Safety equipment
  • Toolboxes
  • Jobsite equipment
  • Specialty trade tools

Smaller tools may be deducted directly. Larger tools or equipment may need to be depreciated or expensed under applicable tax rules.

Materials and supplies

Materials used for client projects may be deductible as cost of goods sold or business expenses, depending on your accounting method and setup.

Examples:

  • Lumber
  • Drywall
  • Fasteners
  • Paint
  • Flooring
  • Concrete
  • Electrical materials
  • Plumbing parts
  • Adhesives
  • Consumables

You should track materials by job whenever possible.

Good job costing helps you understand profit, not just taxes.

Vehicle expenses

Vehicle deductions are important for contractors.

You may be able to deduct business use of:

  • Truck
  • Van
  • Trailer
  • Work vehicle
  • Mileage
  • Fuel
  • Maintenance
  • Repairs
  • Insurance
  • Registration
  • Lease payments
  • Depreciation

There are generally two approaches:

  1. Standard mileage method
  2. Actual expense method

You need good records either way.

Track business miles, jobsite travel, supply runs, and client visits.

Commuting from home to a regular work location may not be deductible in the same way as business travel between jobsites.

Home office deduction

If you use part of your home exclusively and regularly for your contractor business, you may qualify for the home office deduction.

A home office may be used for:

  • Estimating
  • Invoicing
  • Bookkeeping
  • Scheduling
  • Client calls
  • Project planning
  • Administrative work

You can compare methods with the Home Office Deduction Calculator.

The space generally needs to be used regularly and exclusively for business.

Phone and internet

Contractors often use phone and internet for business.

Potentially deductible uses include:

  • Client calls
  • Estimate requests
  • Project photos
  • Scheduling
  • GPS/jobsite coordination
  • Email
  • Invoicing
  • Business apps
  • Supplier communication

If you use the same phone or internet for both personal and business use, only the business portion should be deducted.

Software and subscriptions

Software used for your contractor business may be deductible.

Examples include:

  • Accounting software
  • Estimating software
  • Invoicing tools
  • Project management software
  • CRM
  • Scheduling software
  • Design software
  • Cloud storage
  • Document signing
  • Payroll software
  • Website hosting

Keep invoices and receipts for subscriptions.

Advertising and marketing

Marketing expenses can be deductible if they are for your business.

Examples:

  • Website
  • Domain name
  • Hosting
  • Google Ads
  • Local SEO
  • Business cards
  • Yard signs
  • Truck decals
  • Flyers
  • Photography
  • Lead generation platforms
  • Sponsorships
  • Review management tools

Track which marketing channels generate profitable jobs.

Subcontractor payments

Payments to subcontractors are usually deductible business expenses.

However, you need proper records.

You may need:

  • W-9 forms
  • 1099-NEC reporting
  • Written subcontract agreements
  • Certificates of insurance
  • Workers’ compensation documentation
  • Proof of payment

Misclassifying employees as subcontractors can create tax, insurance, and labor problems.

Employee wages and payroll taxes

If you have employees, wages are generally deductible business expenses.

You may also deduct employer payroll taxes and certain employee benefits.

Payroll creates additional compliance obligations, including:

  • Payroll tax withholding
  • Employer payroll taxes
  • Workers’ compensation
  • Unemployment insurance
  • Wage reporting
  • Time tracking

Do not treat payroll casually.

Education and training

Training may be deductible if it maintains or improves skills used in your current business.

Examples:

  • Code update classes
  • Safety training
  • License renewal courses
  • Estimating courses
  • Business education
  • Trade-specific training
  • Continuing education

Training for a completely new profession may be treated differently.

Professional fees

Contractors may deduct professional services used for the business.

Examples:

  • Accountant
  • Bookkeeper
  • Attorney
  • Tax preparer
  • Business consultant
  • Insurance broker fees where applicable
  • Licensing assistance
  • Payroll service

Good professional help can save more than it costs.

Depreciation

Larger assets may need to be depreciated over time or expensed under applicable rules.

Examples:

  • Vehicles
  • Heavy equipment
  • Computers
  • Trailers
  • Machinery
  • Office furniture
  • Large tools

You can estimate depreciation using the MACRS Depreciation Calculator.

Depreciation rules can be complex, especially for vehicles and equipment.

Meals and travel

Business meals and travel may be deductible when properly documented and genuinely business-related.

Examples:

  • Traveling to an out-of-town jobsite
  • Lodging for business travel
  • Meals during business travel
  • Meeting a client or subcontractor
  • Parking and tolls for business trips

Keep receipts and document the business purpose.

Startup costs

Some contractor startup costs may be deductible or amortized depending on timing and amount.

Examples:

  • Market research
  • Business setup
  • Initial advertising
  • Professional fees
  • Website setup
  • Licensing preparation
  • Training before launch

Startup cost rules can be technical, so review with a tax professional.

For a general startup budget, see Contractor Startup Costs.

Records contractors should keep

Keep records for:

  • Receipts
  • Invoices
  • Bank statements
  • Credit card statements
  • Mileage logs
  • Job costing reports
  • Subcontractor W-9s
  • 1099s
  • Insurance policies
  • License fees
  • Bond invoices
  • Vehicle expenses
  • Home office calculations
  • Payroll records

Good records are the difference between a confident deduction and a problem during review.

Common mistakes

Mixing personal and business expenses

Use a separate business bank account.

Not tracking mileage

Mileage logs are much harder to recreate later.

Forgetting small expenses

Small tools, supplies, parking, tolls, and software add up.

Ignoring depreciation

Large tools and equipment may need special treatment.

Misclassifying workers

Subcontractor vs employee mistakes can be expensive.

Deducting personal expenses

Only business expenses should be claimed.
