Running a business from home comes with flexibility, lower overhead, and one powerful financial advantage: the ability to claim a wide range of business tax deductions. Whether you are a freelancer, consultant, online seller, or service provider, understanding which expenses are deductible can significantly reduce your taxable income and lower your tax bill.
Yet many small business owners overlook key deductions or apply them incorrectly, either leaving money on the table or increasing their audit risk. With the IRS paying closer attention to home office deduction claims and mixed-use expenses, accuracy and proper documentation are more important than ever during tax season.
At Madras Accountancy, we help U.S.-based CPA firms support small businesses with clean, compliant books and optimized tax filing processes. This guide provides a full checklist of home-based business tax deductions, the rules for each category, and what documentation is required to keep you safe in case of an audit.
Any self-employed individual or small business owner who uses a portion of your home regularly and exclusively for business purposes may be eligible to claim business tax deductions. This includes sole proprietors, single-member LLCs, partners, and S-Corp owners with proper reimbursement plans.
Eligibility for the home office deduction is generally tied to two key tests:
If you meet these conditions, you can deduct both direct expenses (100 percent related to the business) and a proportion of indirect home expenses (like utilities, insurance, and rent). The ability to deduct these business expenses can significantly impact your tax return.
There are two ways to calculate your home office deduction when you work from home:
Most tax professionals recommend running both methods to determine which gives the higher deduction. This comparison helps ensure you're able to deduct the maximum allowable amount for your home that you use for business purposes.
Here is a comprehensive list of deductible expenses, including both home-related and general business costs that can reduce your federal tax liability.
This includes expenses for the business use of a part of your home, based on the square footage used exclusively for business.
Key requirement: The space must be used exclusively for business. Occasional personal use invalidates the deduction and affects your ability to claim business use of your home.
These are considered indirect expenses, and only a portion is tax deductible based on the business percentage.
Note: Internet and phone bills must be split if used for both business and personal activities. Only the portion you use for business qualifies as a business expense.
You can deduct the cost of your homeowner's or renter's insurance as it relates to the business space.
Additionally, any business-specific insurance (like general liability or errors and omissions) is 100 percent deductible as a business expense.
Home repairs that directly affect the business space (like fixing a leaky ceiling in your home office) are fully deductible. Repairs affecting the whole home (like HVAC maintenance) are deductible based on the business use percentage.
If you own your home, you may be able to depreciate the business-use portion over 39 years, reducing your taxable income annually.
Be aware that depreciation must be recaptured if you sell your home later, which can create a tax obligation during the tax year of sale.
Standard business supplies are deductible regardless of your work location and represent common business expenses.
Keep receipts for all supply purchases, and do not mix personal and business expenses when claiming these business tax deductions.
Large items can be deducted in the year of purchase under Section 179 or depreciated over multiple years.
For shared-use items (like a family computer), only the business use percentage is deductible. You can deduct the cost proportionally based on how much you use the item to run your business.
Software used to run or support the business is fully deductible. Common examples include:
Annual and monthly subscription fees can both be claimed as business expenses on your tax return.
Expenses to promote your business are fully deductible business expenses.
Make sure personal social media ad spend is kept separate from legitimate business expenses.
Payments to professionals are fully deductible if they are for a business purpose.
Payments to contractors should be documented and reported on the appropriate tax form when applicable.
If you take courses to improve your business skills for your qualified business, the fees may be deductible.
However, the training must relate directly to your current business. Education for a different field or to enter a new business is not deductible.
Travel related to business activities can be a significant tax deduction.
You must maintain a log of travel dates, locations, and business purpose. Commuting between home and another permanent work location is not deductible.
Business meals are 50 percent deductible if they are:
Entertainment expenses are not deductible under the current IRS rules.
Use a dedicated business bank account to clearly track these charges and separate them from personal expenses.
If your home-based business is newly established, you may deduct up to $5,000 in startup costs and $5,000 in organizational expenses in the first tax year.
Examples include:
Excess expenses may be amortized over 15 years.
To claim any deduction related to business use of your home, you must meet strict IRS requirements. The space must be used regularly and exclusively for business purposes. This means:
Mixed-use areas (like a dining room table used for both business and family meals) do not qualify for the home office deduction, even if you work from home regularly.
Your business percentage determines how much of your home expenses you can deduct. Calculate this by:
For example, if your home office is 200 square feet and your home is 2,000 square feet, your business percentage is 10%. You can then deduct 10% of qualifying home expenses.
Small business tax planning goes beyond just claiming deductions. Consider these strategies:
A tax professional can help ensure you're claiming all available credits and deductions while staying compliant with changing tax laws.
Proper documentation is key to keeping your deductions legal and audit-ready.
Failure to document may result in lost deductions or penalties during an audit. This documentation is not an itemized deduction but rather substantiation for your business deductions.
Even well-meaning business owners can make mistakes that increase risk or reduce deductions:
Working with a CPA or outsourcing to firms like Madras Accountancy can help you avoid these issues while staying compliant with your tax obligations.
State rules for home-based deductions may differ from federal rules. For example:
Make sure to consult with a tax advisor familiar with your home state regulations to understand all available business tax benefits.
Those who work from home as independent contractors should track:
Online sellers may be able to deduct:
Professional service providers can often deduct:
Successful small business tax management requires year-round attention, not just preparation at tax time. Consider:
Modern technology can simplify the process of tracking business expenses:
Beyond basic deductions, your business may qualify for additional tax benefits:
Many small business owners benefit from working with qualified tax professionals who understand the complexities of home-based business deductions. A good tax professional can:
Running a business from home offers more than convenience. With proper documentation and awareness, home-based business owners can legally deduct thousands of dollars in expenses, lowering their taxable income and improving cash flow.
From the home office deduction to business travel and software tools, every category comes with its own rules and requirements. Understanding which expenses qualify as business deductions and maintaining proper records for business use of your home are critical for maximizing your tax benefits.
The key to successful small business tax management is treating deduction tracking as an ongoing business process, not just an annual tax time activity. By implementing proper systems and working with qualified professionals, you can ensure that every legitimate business expense is captured, categorized, and compliant.

Question: What home office expenses can home-based businesses legally deduct on their taxes?
Answer: Home-based businesses can deduct home office expenses using either the simplified method ($5 per square foot up to 300 square feet) or actual expense method (percentage of home used for business). Deductible expenses include mortgage interest, property taxes, utilities, insurance, repairs, and maintenance allocated to business use. Additional deductions cover office supplies, equipment, furniture, internet service, phone bills, and business-related travel. The home office must be used regularly and exclusively for business purposes to qualify for these deductions.
Question: How do you calculate the home office deduction using the actual expense method?
Answer: The actual expense method requires calculating the percentage of your home used exclusively for business by dividing office square footage by total home square footage. Apply this percentage to eligible home expenses including mortgage interest, property taxes, utilities, insurance, repairs, and depreciation. For example, if your office is 200 square feet in a 2,000 square foot home (10%), you can deduct 10% of qualifying home expenses. Maintain detailed records of all expenses and measurements to support your calculations during tax filing.
Question: What business equipment and technology expenses are deductible for home-based businesses?
Answer: Home-based businesses can deduct computers, printers, office furniture, business software, internet service, dedicated business phone lines, and mobile devices used primarily for business. Equipment purchases can be deducted immediately using Section 179 expensing up to $1,160,000 annually, or depreciated over time. Technology subscriptions, cloud storage, professional software licenses, and business-related apps qualify as deductible expenses. Maintain purchase receipts and document business use percentage for items used partially for personal purposes.
Question: Can home-based businesses deduct vehicle expenses and how are they calculated?
Answer: Home-based businesses can deduct vehicle expenses using either the standard mileage rate ($0.67 per mile for 2024) or actual expense method tracking fuel, maintenance, insurance, and depreciation. Business mileage includes trips to clients, suppliers, business meetings, and professional development events, but excludes commuting from home to a regular workplace. Maintain detailed mileage logs with dates, destinations, business purposes, and odometer readings. The actual expense method requires calculating business use percentage and applying it to total vehicle costs.
Question: What professional services and business development expenses can home-based businesses deduct?
Answer: Home-based businesses can deduct professional services including legal fees, accounting costs, business consulting, marketing services, and website development. Educational expenses for business skills development, professional memberships, trade publications, and conference attendance qualify as deductions. Business insurance premiums, professional licenses, permits, and certification costs are fully deductible. Networking events, business meals (50% deductible), and client entertainment expenses also qualify when directly related to business activities and properly documented.
Question: Are there limitations or restrictions on home-based business tax deductions?
Answer: Home-based business deductions cannot exceed business income, meaning losses cannot be created solely through home office deductions. The home office must be used regularly and exclusively for business - occasional use or mixed personal/business use disqualifies the space. Employees cannot claim home office deductions unless working from home is for employer convenience. Business use must be substantial and regular, not just occasional or incidental. Documentation requirements are strict, requiring detailed records, receipts, and proof of business purpose.
Question: What records should home-based businesses maintain to support their tax deductions?
Answer: Home-based businesses should maintain comprehensive records including receipts for all business expenses, bank and credit card statements, invoices and payment records, mileage logs with detailed trip information, and photos of the home office space. Keep utility bills, mortgage statements, property tax records, and home maintenance receipts to support home office deductions. Document business use of equipment and vehicles, maintain client meeting records, and preserve all professional service agreements and contracts supporting business expense claims.
Question: How do home-based business deductions affect future tax situations like selling your home?
Answer: Home office deductions can impact home sale taxation by requiring depreciation recapture on the business portion of the home. When selling, you must pay taxes on depreciation claimed for the home office space, even if using the simplified method. However, the home sale exclusion (up to $250,000 for single filers, $500,000 for married couples) still applies to the residential portion. Consider consulting tax professionals before selling to understand potential tax implications and strategies for minimizing depreciation recapture obligations.
