NEXT IN SERIES >> Canadian Home Office Expense Deduction


As a small U.S. business owner, you may be eligible to deduct expenses related to a home office if you use a portion of your home exclusively and regularly for business purposes. There are two methods to calculate the home office deduction: the Regular Method and the Simplified Option.

Home Office Deduction: Eligibility Requirements

The IRS sets out clear requirements for what is acceptable for calling a space a home office.

  • Exclusive Use Test: The home office space must be exclusively used for business purposes. Personal use of the space can disqualify the deduction. This rules out claiming the dining room table or your guest bedroom as your office space.
  • Regular Use Test: You must regularly use the home office space as your primary place of business or for substantial administrative or management activities. Your best bet is to setup some kind of logbook (paper or digital) as a time clock for documentary evidence.
  • Employment Status Test: As part of the Tax Cuts and Jobs Act of 2017, the ability for employees to deduct unreimbursed business expenses, including those for a home office, through 2025 was suspended. The deduction is primarily available to self-employed individuals, such as independent contractors, freelancers, and small business owners.

Adhere to these criteria to support your right to claim the home office deduction. A home office deduction may not always in your best interests.

Home Office Deduction : Regular Method

The Regular Method involves calculating the actual expenses incurred for maintaining the home office. Here’s how it works:

  1. Direct Expenses: Expenses that are specifically for the office, like painting or repairs specifically made to that area, are fully deductible.
  2. Indirect Expenses: These are general home maintenance expenses such as mortgage interest or rent, utilities, and insurance. You must calculate the percentage of your home that is used for business purposes (square footage of the office divided by total square footage of the home) and apply that percentage to your indirect expenses.
  3. Depreciation: You can also depreciate the portion of your home used for business. This can add to the complexity of calculations but may result in a larger deduction. Please see 'Impact on Sale of Home' under Considerations below before you claim this expense.
  4. Record Keeping: Maintaining detailed records and receipts of all expenses to substantiate your deduction is crucial under the Regular Method.

Audit Ready
This option requires keeping meticulous records but may provide you with the largest tax savings. Ensure you have copies of all your bills and receipts for any expense you claim to protect you in the event of an IRS audit. You must be aware of the potential impact of future taxes if you claim depreciation.

Home Office Deduction: Simplified Method

The Simplified Option, introduced by the IRS in 2013, is designed to relieve some of the administrative burden associated with the Regular Method.

  1. Standard Deduction: You can claim $5 per square foot of your home office space, up to a maximum of 300 square feet, allowing for a maximum deduction of $1,500 per year.
  2. No Depreciation: With the Simplified Option, you don't have to calculate depreciation, which simplifies the record-keeping process.
  3. Carryover of Unused Deductions: Unlike the Regular Method, where unused expenses can be carried over to future years, the Simplified Method doesn’t allow for carryover.

This option is quick and easy but may not provide you with the largest tax savings.

Home Office Deduction: Comparing Methods

  • Complexity: The Regular Method is more complex and requires meticulous record-keeping, while the Simplified Option is straightforward with less paperwork.
  • Potential Savings: If your business use of home is large and you have substantial deductible expenses, the Regular Method may offer greater tax savings.
  • Flexibility: You can switch between methods each year. Depending on your situation, you might choose the Simplified Option one year and the Regular Method the next. However, it's my understanding it is more prudent to select one method and stick with it unless you have a change in circumstances that warrants a change in method.

Considerations:

  • Size of Deduction: Calculate both methods to see which yields a larger deduction.
  • Your Situation: Consider how much time and effort you can invest in documentation and record-keeping.
  • Impact on Sale of Home: If you claim depreciation under the actual expense method, it may affect the taxable gain on the sale of your home later on due to the recapture of depreciation.
  • IRS Scrutiny: Both methods require adherence to IRS rules, but the actual expense method may invite more scrutiny. Claiming the home office deduction may potentially increase the likelihood of an IRS audit. (There is some debate on whether this has any truth.)
  • Part-Year Use: If you only used your home office for part of the year, you'll need to adjust your calculations accordingly.
  • Limitation on Loss Deduction: Your home office deduction may not create or increase a business tax loss.

When It Might Be Good to Claim the Home Office Deduction?

In the back of your mind, there is probably the lingering question of whether you should claim the home office deduction. To help you with this question, here are some things to consider:

  1. High Proportion of Home Used for Business: If a significant portion of your home is dedicated to your business, the actual expense method might result in a more substantial deduction.
  2. Significant Business-Related Expenses: If you incur substantial home-related expenses (e.g., high mortgage interest, rent, or utility costs), the actual expense method could provide a higher deduction.
  3. Minimizing Tax Liability: If you are looking to reduce your taxable income and tax liability, and your record-keeping is thorough, the actual expense method can be more beneficial.
  4. Simplicity and Time Constraints: If simplicity and convenience are important to you, and your home office is relatively small, the simplified method may be sufficient and less time-consuming.

Home Office Deduction: Which Method is Best?

Ultimately, the best option depends on your specific situation, including the size of your home office, the complexity of your expenses, and your preference for simplicity versus potential tax savings.

Consulting with a tax professional can provide personalized guidance and point out potential audit issues or any future tax impacts such as how claiming depreciation may impact the sale of your home in the future.

Audit Ready
No matter which method you choose, it is always wise to take a picture of your dedicated office space as well as a floor plan of your home to prove the square footage claimed. Keep them in your tax file as documentary evidence.

Home Office Deduction Questions

What Are The Pros And Cons Of Taking The Home Office Deduction?

It's important to evaluate these to see if the home office deduction is beneficial for your specific situation:

Pros of Taking the Home Office Deduction:

  1. Tax Savings: The most immediate benefit is the potential tax savings. By deducting expenses related to your home office, you can lower your taxable income, thereby reducing the amount you owe in taxes.
  2. Deduct a Portion of Home Expenses: You can deduct a portion of your rent or mortgage, utilities, insurance, and even maintenance costs that are related to the business use of your home.
  3. Direct Business Expense: If you qualify under the simplified method, you can deduct $5 per square foot of your home office up to a maximum of 300 square feet, without the need to track individual expenses.
  4. Boosts Deductibility of Non-Deductible Expenses: Some expenses, like home maintenance, that might not be otherwise deductible can become partially deductible when allocated to a home office.


Cons of Taking the Home Office Deduction:

  1. Eligibility Requirements: The area must be used exclusively and regularly for business purposes. This can be difficult if your space serves multiple purposes. Many find the "exclusive use" requirement particularly challenging.
  2. Record-Keeping Complexity: Keeping detailed records of expenses and use of space can be burdensome, especially if you choose to itemize instead of using the simplified method. You need to track and keep receipts and other proof of payments related to your home office.
  3. Potential for IRS Scrutiny: Home office deductions can be seen as red flags for audits, particularly if it appears the space may not be used solely for business. Ensuring compliance with all rules is a must ... no wiggle room here.
  4. Capital Gains Tax Implications: When selling your home, having claimed depreciation on your home office space might affect your capital gains tax calculation. This could result in tax implications on the portion of your home used for business, even with an otherwise tax-free sale. This does not apply if you chose the Simplified Method to claim your home office deduction.
  5. Exclusivity Limitation: The space designated as a home office cannot be used for personal activities, which can be restrictive.


Choosing to take the home office deduction should be carefully considered against these pros and cons. If uncertain, consulting with a tax professional can help assess the potential benefits and any complications in your individual situation.

Can I use a guest bedroom that has a hide-a-bed couch as my home office?

For a space in your home to qualify for the home office deduction, it must meet the "exclusive use" requirement. This means that the area you claim as a home office must be used solely for your business activities, with no personal or family use allowed.

If the guest bedroom with a hide-a-bed couch is occasionally used for personal purposes, such as hosting guests, it would generally not meet the exclusive use requirement. The presence of personal-use furniture like a couch that turns into a bed suggests potential non-business use, which could disqualify that space from being claimed as a home office.

However, if the room is partitioned or a specific area of the room is used exclusively for business and the rest remains unused for personal purposes, you might still be able to qualify for that particular portion of the room. Clear documentation or evidence that a part of the room is exclusively and regularly used for business would strengthen your case.

Ultimately, the IRS is firm on this rule, so it's important to maintain clear boundaries between personal and business use to qualify for and sustain the home office deduction. If in doubt, consulting with a tax professional can offer guidance tailored to your specific situation.

What happens if claiming the home office deduction creates a loss?

If you are a small business owner working from home and claiming the home office deduction, it's important to understand how it can impact your tax situation, particularly if it results in a business loss.

Here’s what happens if claiming the home office deduction creates a loss:

  1. Limitation on Loss Deduction: The home office deduction cannot create or increase a net loss from your business. This means that your net business income (before the home office deduction) must be greater than zero for the deduction to apply fully. You can only deduct business expenses up to the amount of your business income. Other operating expenses and business-related costs are usually deducted first, and the home office deduction is limited to any remaining income.
  2. Carrying Forward Unused Deduction: If the deduction contributes to or exceeds your net profit, the portion of the deduction that cannot be used to offset income in the current year may be carried forward to the next tax year. Any home office deduction not utilized in the current year can potentially be applied to future years when your business generates sufficient income to allow the deduction.
  3. Considerations: If your business consistently generates low or negative income, it might be beneficial to reassess business strategies or consult with a tax advisor to optimize your tax situation effectively.

Is there is a specific percentage of square footage or amount that automatically raises a red flag with the IRS when making the home office deduction?

While there is no specific percentage or amount that automatically increases IRS scrutiny, there are some best practices and general rules to consider:

  1. Proportionate Deduction: The IRS expects the percentage of your home used for business to be reasonable. Typically, claiming more than 15-20% of your total home as a home office may prompt closer examination, especially if your claim seems disproportionate to the nature of your business.
  2. Consistency and Credibility: Ensure that the percentage claimed is consistent with the business activities carried out. A small business run primarily online might justify a smaller claimed space than a business that involves physical inventory storage or frequent client visits.
  3. Actual vs. Simplified Method: You can choose between the Actual Expenses Method, which involves specific calculation and documentation of expenses, or the Simplified Option, which allows a standard deduction based on square footage (up to 300 square feet at $5 per square foot, capped at $1,500).
  4. Exclusive and Regular Use: The space you claim must be used exclusively and regularly for business purposes. It should not be a shared space for personal activities. For example, a desk in your living room where you occasionally work would not qualify.
  5. Documentation: Keep detailed records of your home office dimensions, how the space is used, and all relevant expenses. Be prepared to justify your claim with evidence during an audit.

The key to minimizing scrutiny is ensuring your claims are reasonable and well-documented according to your specific business situation and IRS guidelines.

Are there special rules around deducting capital expenditures for the home office deduction such as my desk, chair, bookshelves, or my cell phone and computer.

As a small business owner working from home, you can indeed deduct certain expenses for items like your desk, chair, bookshelves, cell phone, and computer, but these are generally not deducted as part of the home office deduction itself. Instead, they are classified under different categories:

1. Capital Expenditures for Equipment and Furniture:

  • Depreciation: Items like your desk, chair, or computer are typically considered capital assets. You can recover the cost of these items through depreciation, deducting a portion of their cost over several years.
  • Section 179 Deduction: In some cases, you might be eligible to expense the full cost of these items in the year they are purchased, rather than depreciating them over time, up to a certain limit, using the Section 179 deduction. This can be particularly beneficial for small businesses.
  • Bonus Depreciation: You might also qualify for bonus depreciation, which allows you to write off a large percentage of the asset's cost in the year it is placed in service.

2. Cell Phone and Computer Expenses:

  • Business Use Percentage: If your cell phone and computer are used for both business and personal purposes, you must allocate the expenses based on the percentage of business use. Only the portion of expenses related to business use is deductible.
  • Regular Business Expense Deduction: Once you've determined the business use percentage, deduct the relevant portion as a business expense.

3. Home Office Deduction:

  • This specific deduction applies more to the space itself – the proportionate share of rent or mortgage, utilities, and other similar expenses tied directly to having a dedicated workspace in your home used regularly and exclusively for business.


Takeaway
To summarize, while your home office deduction covers workspace-related utility and occupancy costs, equipment and furniture are usually capitalized and either depreciated or deducted through special provisions like Section 179 or bonus depreciation. Capital expenditures are usually not fully deductible in the current year but deducted over the life of the asset with exceptions for Section 179 or bonus depreciation provisions.

What home maintenance costs are allowed under the home office deduction?

The IRS allows you to deduct expenses related to the portion of your home that is used exclusively and regularly for business. This means:

  1. Only Include Business-Related Expenses: You can deduct a portion of your home expenses, but only those that are connected to the business use of your home. This includes expenses for the entire house, like mortgage interest, rent, utilities, and insurance, but only the business-use portion (which is generally based on the square footage of your home office relative to your entire home).
  2. Calculating the Deduction: You typically determine the ratio of your home that is used for business by dividing the square footage of your home office by the total square footage of your home. This ratio is then applied to the eligible expenses.
  3. Exclude Personal Use Expenses: Any expenses that relate solely to personal use areas of your home are not deductible. For instance, if a repair is made in a room that is not part of your home office, you cannot deduct that cost.
  4. Personal Use Expenses Are Never Deductible: Purely personal expenses are explicitly excluded from business deductions. The IRS is quite strict on this to avoid cross-subsidizing personal living costs with business deductions.

Examples

As a small business owner working from home, here are examples of when a maintenance or repair expense might be claimable and when it would not:

1. Claimable Example - Repair to Your Home Office Space

Let's say you have a dedicated room in your home that you use exclusively as your office space. If you need to repair the windows in this office room due to a draft or damage, the cost of this repair can be fully deductible because it is directly related to your business use of that specific space.

2. Non-Claimable Example - Repair in a Non-Office Space

If you have to fix a leaky faucet in your kitchen, this expense is not claimable as a home office deduction. The kitchen is not part of the space used exclusively and regularly for business purposes, so the expense is considered personal.

3. Partially Claimable Example - Repair to Whole Home

If a repair impacts both the office and personal spaces (for instance, a roof repair or heating system service), you might be able to deduct a portion based on the percentage of your home that is used for business. This allocation is based on the square footage that you use exclusively for business relative to your entire home.

Audit Ready
Always ensure that you maintain accurate records and documentation for expenses you plan to deduct. By maintaining clear boundaries between personal and business expenses and keeping good records, you ensure that your deductions are legitimate and compliant with IRS guidelines.

How does having a home office affect my home insurance policy?

As a small business owner working from home, there are a few considerations regarding your home insurance policy when you have a home office:

1. Review Your Current Homeowners Insurance Policy:

  • Coverage Limits: Check if your homeowners insurance policy covers business equipment and inventory. Many standard policies have limited coverage for business-related items.
  • Liability Coverage: Standard homeowners policies may not cover liability claims related to business activities conducted in your home.

2. Consider Home Office or Business Insurance:

  • Rider or Endorsement: You might be able to add a rider or endorsement to your existing homeowners policy to cover business equipment or liability.
  • Business Owners Policy (BOP): If your business activities and risks are significant, you might need a separate business policy, like a Business Owners Policy, which can provide property and liability coverage.

3. Communicate with Your Insurance Provider:

  • Disclosure: It’s essential to inform your insurance provider if you're using part of your home for business purposes. Failing to disclose this could affect your coverage; in some cases it may even invalidate your policy.
  • Evaluate Needs: Discuss your specific business activities with your insurer to determine the appropriate coverage. They can help assess risks and recommend suitable coverage options.

4. Document Your Office and Equipment:

  • Inventory: Keep a detailed inventory of business equipment, along with receipts and photographs, which can be valuable in case of a claim.
  • Usage Details: Maintain records of how your home office is used for business, including the percentage of space dedicated to office use, which may also impact tax deductions.


By taking these steps, you ensure that your home office is adequately covered and help protect your business assets. It would be prudent to discuss how your home office affects your policy with you insurance agent for tailored advice based on your specific business operations.

My home insurance policy has separate coverages for personal property items? How does this affect my home office deduction?

Additional insurance coverage for items like a boat or jewelry would typically need to be excluded from the home office deduction calculations for prorating insurance costs. Here's a breakdown of how this works:

Prorating Insurance for Tax Deductions

  1. Home Office Deduction Basics: The home office deduction allows you to deduct a portion of your home expenses related to the space used exclusively for business purposes. This includes costs like mortgage interest, utilities, repairs, and insurance.
  2. Calculating the Deduction: To calculate the deductible amount, you determine the percentage of your home used for business purposes (usually based on square footage). This percentage is then applied to your total allowable home expenses.
  3. Exclusion of Specific Items and Additional Coverage: Insurance for specific items like boats or jewelry is typically considered personal rather than business-related. Therefore, the premiums for these additional coverages should be excluded from the base insurance amount used to calculate the home office deduction.

Example

If your homeowners insurance premium is $1,500 annually, and $300 of that is for extra coverage on a boat, the base amount for your home office deduction would be $1,200. You would apply the percentage of your home office use to the $1,200, not the full $1,500.

Any expenses that relate solely to personal use are never deductible; or said another way, personal expenses are explicitly excluded from business deductions. The IRS is quite strict on this to avoid cross-subsidizing personal living costs with business deductions. This approach helps ensure that your home office deduction accurately reflects only the business use of your home. 

I am a small business owner based in the U.S.. Should I enter my home office expenses related to the home office deduction in QuickBook Online (QBO)?

As a small business owner using QuickBooks Online (QBO) for your bookkeeping, deciding how to handle home office expenses depends on how you want to track them for both management and tax purposes. Here are a few considerations to guide you:

Tracking Home Office Expenses

1. Using QuickBooks Online (QBO):

  • Pro: Centralized Record Keeping: Entering home office expenses in QBO can help you maintain a centralized record of all business-related expenses, making it easier to manage your finances and prepare for tax season.
  • Pro: Accurate Reporting: This approach allows you to generate reports showing your total business expenses, including those related to your home office, which can provide valuable insights into your business operations.
  • Con: Complexity: You need to ensure that these expenses are clearly categorized to separate personal and business use, which can become complex if not managed carefully.


2. Separate Tax Working Paper:

  • Pro: Simplified Process: Keeping a separate worksheet or tax document specifically for home office deductions might simplify your QBO records by avoiding mixing personal and business expenses.
  • Pro: Focused Tax Documentation: This approach ensures that your home office expense deduction is well-documented and easily accessible when preparing your tax return.
  • Con: Lack of Integration: You may need additional effort to integrate these deductions into your broader financial reporting and tax preparation processes.


Recommendation
Personally, I don't recommend recording home office expense deduction in QBO mainly because if I didn't have my business, I'd still have these expenses. They just wouldn't be tax deductible. That said, 

  • For Small Businesses: It often depends on the complexity of your business and your comfort level with bookkeeping. If you have a straightforward setup and prefer maintaining everything in QBO, consider creating a separate account to track home office expenses. You will need to book only the prorated or net amount.
  • For Tax Preparation: Whether you record in QBO or separately, you should maintain clear documentation to support any deductions claimed on your tax return, including calculations of the business use percentage of your home.


Takeaway
If you prefer keeping things consolidated in QBO for convenience and clarity, ensure you have a systematic way to document and categorize these expenses.

What happens when I sell my home if I claimed depreciation as part of my home office deduction?

Please verify this with your accountant but I believe this is the impact on the sale of your home:

Section 121 Exclusion

  • Exclusion of Gain on Sale: Generally, you can exclude up to $250,000 of gain ($500,000 for married filing jointly) from the sale of your principal residence if you meet ownership and use tests.
  • Business Use and Depreciation Recapture: If part of your home is used for business, the exclusion doesn't apply to that portion of your home if you depreciated it. Unrecaptured Section 1250 gain related to depreciation taken on the home office after May 6, 1997, isn't eligible for the exclusion and must be recaptured at a maximum 25% tax rate upon sale.
  • Mixed-Use Property: If the home office is within the principal residence and not a separate structure, you generally may still qualify for the full exclusion for the portion of the gain related to non-depreciated personal use. As long as (a) your home office is part of your main residence and not a separate structure, and (b) you didn't claim depreciation on it; you should still be able to take advantage of the principal residence gain exclusion when you sell your home, except for any gain due to the depreciated part.

As this is not my area of expertise, I encourage you to clarify these rules with your accountant.
