Home-Based Business Tax Deductions: Definition, Types and Methods of Calculations

Home-based businesses offer many opportunities to grow a passive source of income, build their hobbies, or start a side hustle. Despite the flexibility and convenience of home-based business, there’s a practical aspect that every homepreneur must embrace: taxes. Do you know that you can reduce the burden of taxes by utilizing Home-based business tax deductions?

Home-based business tax deductions are like hidden treasures that allow you to navigate the tax terrain efficiently, ensuring that your hard-earned money stays where it belongs – in your business. So, let’s embark on a journey where you will learn about home-based business tax deductions, their requirements, benefits, and the mode of calculations. 

What are Home-Based Business Tax Deductions?

Home-based business tax deductions are specific expenses that individuals or businesses operating from their homes can legally subtract from their taxable income to reduce their overall tax liability. These deductions are designed to account for the costs of running a business from a home office or workspace. 

Home-based tax deductions help ensure that individuals and businesses are not taxed on income they reinvest in their businesses or spend on necessary business-related expenses. These deductions include expenses related to home use, business-related supplies and equipment, and other qualified business expenditures. 

Types of Home-Based Business Tax Deductions 

1. Home Office Deduction 

Home Office Deduction is a tax benefit that individuals can use a portion of their home for business purposes to deduct certain home-related expenses from their taxable income. To qualify for the Home Office Deduction, you must meet specific criteria, and they include the following:

  • Exclusive and Regular Use: The area claimed as a home office must be used exclusively and regularly for business purposes. It should be your primary place of business or where you meet clients/customers regularly.
  • Principal Place of Business: Your home office should be your principal place of business, where you conduct the most substantial portion of your work or use it for administrative or management activities if you have no other fixed location to conduct business.

There are two methods to calculate this deduction:

Simplified Method:

The simplified method is straightforward and doesn’t require detailed record-keeping of home-related expenses. To use this method, you must first calculate the square footage of your home office space by multiplying the square footage by the prescribed rate (e.g., $5 per square foot) to determine your deduction.

Regular Method:

This method details the records of all expenses and maintains documentation to support your calculations.

Here are the steps involved when using the regular method:

  • Determine the total square footage of your home.
  • Measure the square footage of your home office.
  • Calculate the percentage of your home used for business (Home Office Square Footage / Total Square Footage).
  • Allocate a portion of home-related expenses (e.g., mortgage interest, property taxes, utilities, insurance, repairs) based on the above percentage.

2. Business Expenses

Business expenses are incurred by a business in its operations to generate revenue and maintain its daily activities. These expenses are tax-deductible, meaning they can be subtracted from a business’s total revenue to determine its taxable income. 

This home-based business tax deduction reduces a business’s tax liability, resulting in potential cost savings.

Common types of business expenses include:

  • Rent
  • Utilities
  • Office Supplies
  • Insurance
  • Professional Services
  • Bank Fees
  • Licenses and Permits
  • Subscriptions and Memberships
  • Travel Expenses
  • Training and Education
  • Salaries and Wages

3. Internet and Phone Expenses

Internet and phone expenses are indispensable expenses that every business owner must incur while running their business. The good news is that these expenses can be deducted from your tax. These deductions reduce your taxable income, which can lead to lower income taxes. 

One of the significant ways to save these expenses is to create a separate business and personal usage account, as this helps you to track and manage how much you spend monthly. If you have a dedicated business line, you can generally deduct the full cost of that line. For a personal phone with a mix of business and personal calls, you should only deduct the expenses directly related to business calls.

4. Mileage Deduction

One of the essential home-based business deductions is the mileage deduction. This tax deduction allows individuals and businesses to deduct certain vehicle-related expenses associated with using a vehicle for business, medical, moving, or charitable purposes. It is a way to account for the cost of operating a vehicle for these specific purposes without the need to itemize individual expenses.

The mileage deduction can claimed if you use your vehicle for specific purposes related to your business, medical care, moving, or charitable activities. The IRS sets standard mileage rates for different purposes. These rates are updated annually. However, you cannot switch between methods from year to year, so choosing the method that provides the maximum benefit is essential.

To calculate the deduction for a particular purpose, multiply the miles driven by the applicable standard mileage rate. For example, if you drove 1,000 miles for business purposes in a year, your business mileage deduction would be 1,000 miles x 56 cents per mile = $560.

5. Travel Expenses

Travel expenses incurred for business purposes can be tax-deductible, which means you can reduce your taxable income by deducting the costs associated with business-related travel. 

However, you should follow specific rules and guidelines to claim these deductions correctly. Firstly, your travel expenses are deductible only if necessary for your business and serve a legitimate business purpose.

Eligible types of business travel may include:

  • Travel to meet with clients or customers
  • Attending conferences, seminars, or trade shows
  • Travel for training or educational purposes
  • Visiting business locations or suppliers
  • Travel for prospecting and business development

Everyday deductible travel expenses include:

  • Transportation Costs: This includes airfare, train or bus tickets, rental car expenses, and mileage for your vehicle.
  • Lodging: Hotel or accommodation expenses while traveling for business.
  • Meals: Deductible meal expenses are generally limited to 50% of the cost.
  • Communication: Business-related phone calls, internet access, and fax services costs.
  • Registration Fees: Fees for conferences, seminars, or business-related events.
  • Transportation to/from Business Locations: Expenses for transportation between your place of lodging and business-related locations.
  • Baggage Fees: Fees for checked luggage while traveling for business.
  • Parking and Tolls: Expenses for parking and tolls incurred during business travel.
  • Business Equipment Rental: Rental fees for laptops or projectors for business presentations.
  • Other Necessary Expenses: Any other expenses directly related to your business travel.

6. Health Insurance Premiums

Health insurance premiums paid by self-employed individuals can be tax-deductible under certain conditions. The deduction for health insurance premiums can help reduce your taxable income, which lowers your overall tax liability. 

  • To qualify for this particular home-based tax deduction, you generally must meet the following criteria:
  • You must be self-employed 
  • You must not be eligible for health insurance coverage through an employer (including coverage through a spouse’s employer).
  • The health insurance plan must be established under your business (or a partnership if you are a partner).

The deduction is available for various types of health coverage, including medical, dental, and long-term care insurance.

7. Retirement Contributions

Contributing to retirement accounts is a smart financial planning strategy and can also provide tax benefits. It is one of the beneficial home-based tax deductions that help individuals save for their future while reducing their taxable income. 

Here are some common retirement accounts and how contributions to these accounts can impact your taxes:

Traditional Individual Retirement Account (IRA):

Retirement contributions to an IRA are tax-deductible in the year you make them, subject to annual limits. The IRS sets annual contribution limits, which may vary depending on age and income.

Your contributions reduce the amount of your taxable income for the current tax year. When you withdraw money from a traditional IRA in retirement, you’ll pay income tax.

401(k) or 403(b) Retirement Plans:

Contributions to employer-sponsored 401(k) or 403(b) retirement plans are also tax-deductible.

Contributions are typically made through payroll deductions, reducing your annual taxable income.

Employers may offer matching contributions, which can further boost your retirement savings.

Self-Employed Retirement Plans:

Self-employed individuals can contribute to retirement plans like a Simplified Employee Pension (SEP) IRA or a Solo 401(k). Contributions to these plans are tax-deductible for the self-employed person’s business, reducing their business income. Contribution limits for these plans depend on the specific plan and your income.

8. Interest and Property Taxes

Interest and property taxes are common expenses associated with homeownership, and they can have tax implications. However, in many countries, mortgage interest paid on a qualified mortgage loan can be tax-deductible. To be eligible for this deduction, you must outline your deductions on your tax return.

There are limits to the amount of mortgage debt you can claim the deduction. For example, in the U.S., you can generally deduct interest on mortgage debt up to $750,000 ($1 million for loans taken before December 16, 2017).

Interest paid on line of credit or home equity loans may also be deductible in some cases, subject to certain limitations and restrictions.

Also, similar to the mortgage interest deduction, you must outline your deductions to claim the property tax deduction. These tax deductions can help you reduce your tax liability. 

9. Utilities

Utilities are essential services that include electricity, gas, water, and other services necessary for everyday living and conducting business operations. These expenses attract tax implications, especially for businesses and individuals who use a portion of their home for work purposes or operate a home-based business. 

You may be eligible for a home office deduction if you use a portion of your home exclusively for business purposes. This deduction includes a portion of your utility expenses related to the area used for business. To claim this deduction, you typically need to calculate the percentage of your home used for business, and then you can deduct that percentage from your utility bills. Keep in mind that the space must be used solely for business purposes.

How to Calculate Home-Based Business Tax Deductions 

Calculating home-based business tax deductions involves identifying eligible expenses and determining the portion that can be attributed to your home-based business. 

Here’s a step-by-step guide on how to calculate home-based business tax deductions:

  1. Identify Eligible Expenses:

Start by identifying the expenses related to your home-based business that may be eligible for tax deductions. Common qualified expenses include home office expenses, business supplies, communication expenses, marketing and advertising fees, mileage fees, and business insurance.

2. Determine the Business Use Percentage:

To calculate your home-based business tax deductions, you’ll need to determine the percentage of your home-related expenses that can be attributed to your business. This is typically based on the square footage of your home office relative to the total square footage of your home.

3. Allocate Expenses:

Multiply the total cost of each eligible expense by the business use percentage you calculated in the previous step. This will give you the deductible portion of each expense. For example, if your home office represents 10% of your home’s square footage, you can deduct 10% of your eligible home-related expenses.

4. Keep Detailed Records:

Maintain accurate and detailed records of all expenses, including receipts, invoices, bills, and supporting documentation. Good record-keeping is crucial in case of an audit.

5. Report Deductions on Tax Return:

When filing your tax return, report the calculated deductions in the appropriate sections. You may use specific forms or schedules to report home-based business deductions depending on your tax jurisdiction.

6. Consult a Tax Professional:

Tax laws and regulations related to home-based business deductions can be complex and may change over time. Consult with a tax professional knowledgeable about your jurisdiction’s tax laws. They can guide you in maximizing your deductions while complying with tax regulations.


The primary benefit of home-based business tax deductions is that they enable you to save money, which you can reinvest into your venture, fueling its growth and sustainability. As a home-based business owner, ensure you embrace the knowledge and strategy that home-based business tax deductions offer. With these insights, you can build a foundation of financial strength for your home-based enterprise, ensuring that your passion project continues to flourish and save more money.
