What Are Business Tax Write-Offs and How Do They Work?

Every business must file and pay taxes, but understanding how to report financial information properly can help reduce the burden. By taking advantage of business tax write-offs, you can deduct expenses incurred in the course of running your company and lower your tax liability. Careful tax planning and consistent recordkeeping will ensure you benefit from every deduction available to you and give you the documentation needed to calculate and report your qualifying deductions to the IRS accurately.

Tax Write-Off Meaning: What Is a Business Write-Off?

A tax write-off refers to any business deduction allowed by the IRS for the purpose of lowering taxable income. To determine what qualifies for a write-off, the IRS uses the terms "ordinary" and "necessary." In other words, an expense must be necessary and appropriate to the operation of your type of business. Generally, tax write-offs fit into specific reporting categories such as business travel, advertising, or home office expenses.

Due to their ability to reduce taxable income, tax write-offs may play a part in your everyday business decisions throughout the year. For example, traveling to attend an industry conference may seem cost-prohibitive, but if you can deduct all or part of the conference fees, lodging, and mileage for tax purposes, you may make a different decision. When the time comes for tax preparation, you should be familiar with the types of costs the IRS allows businesses to write off.

Tax Deduction vs. Tax Write-Off

When giving tax advice, tax professionals or accountants may use the terms tax deduction and tax write-off interchangeably. There is no real difference between them, and both refer to an amount that reduces taxable income.

Tax Credit vs. Tax Write-Off

Unlike a tax deduction, a tax credit is not the same as a tax write-off. While tax write-offs reduce business income, a tax credit lowers the actual tax liability. If a company generates $10,000 in revenue and deducts the $1,000 cost of a business insurance policy, its net taxable income will become $9,000. The cost of the business insurance would be a tax write-off.

A business tax rate will then be applied to the $9,000 to determine the amount of taxes owed. Given a 10% tax rate, the resulting tax liability would be $900.

Companies may further reduce the amount of taxes owed with a business tax credit. Tax credits are allowed for various purposes, such as small businesses funding a pension or health care plan. Continuing the example above, if a company qualifies for a $500 tax credit, it would then pay $400 in taxes rather than $900.

How Do Business Tax Write-Offs Work?

Tax write-offs for your business are calculated using expense tracking reports. Throughout the year, it's essential to keep records for all business-related expenses. Developing a system that groups expenses into categories that match the IRS forms may prove helpful when compiling year-end tax reports. This will ensure that you do not miss any potential write-offs. If you use tax software, you may be prompted to enter common expenses that qualify as a tax write-off.

What Types of Businesses Can Benefit from Write-Offs?

Nearly every business can realize tax savings by writing off business expenses. Understanding how these deductions apply to your business structure helps ensure you take advantage of every tax benefit available to your organization.

Self-Employed

Self-employed consultants, independent contractors, freelancers, and gig economy workers can deduct expenses like home office space, professional equipment, and business-related travel. Since self-employed individuals handle both employer and employee portions of self-employment tax, these tax write-offs can be particularly beneficial in helping them keep more of their income.

Small Businesses

Sole proprietorships, partnerships, and LLCs can leverage an even broader range of deductions, including business insurance, employee wages, equipment, inventory, software subscriptions, and client outreach expenses. For example, a local restaurant can write off kitchen equipment and maintenance costs, while a retail shop can deduct store rent and unsellable inventory. Service-based businesses like law firms or marketing agencies can benefit from deductions on professional software subscriptions, client entertainment expenses, and continuing education for their staff.

Corporations

Corporations, both C-corps and S-corps, typically have the most extensive deduction opportunities due to the scale and complexity of their operations. These larger entities can take advantage of significant write-offs for research and development, employee benefit programs, and large-scale equipment purchases. Manufacturing corporations, for instance, can deduct costs related to production facilities and machinery, while technology companies can write off substantial investments in software development and digital infrastructure.

Nonprofits

Nonprofit organizations, while tax-exempt on mission-related income, can still benefit from deductions on their unrelated business income (UBI). For example, a nonprofit museum may be able to deduct expenses related to its gift shop operations or facility rentals, even though its primary educational activities remain tax-exempt.

What Can You Write Off on Taxes? Standard Tax Deductions for Small Businesses

So, what are tax-deductible expenses? The IRS provides comprehensive guidance on which business expenses you can write off. If you have an expense that does not fit into a general category, it pays to research whether the cost may be deductible for tax purposes. Here's a small business tax deductions checklist to help you identify some of the most common tax deductions for business owners.

Startup and Organizational Costs

Startup costs (the costs of creating a business) and organizational costs (the costs of creating a corporation or partnership) are generally considered capital expenditures. However, you can deduct $5000 for costs up to $50,000 in each of these cost categories.

Advertising and Marketing Expenses

You can deduct costs related to marketing your business and finding new customers as advertising expenses. This may include developing and printing promotional materials, the cost of a social media campaign, website creation and maintenance, or any ads used to draw in new business.

Legal and Professional Fees

If you pay an accountant, lawyer, or other financial professional to help run your business, their fees may be deductible for tax purposes. Legal and professional fees are fully deductible if they are related to the operation of your business and documented correctly. Legal fees paid to acquire business assets are not deductible.

Business Insurance

The cost of business insurance policies purchased for your business may be written off against taxable income. Most types of insurance qualify, including fire, theft, flood, liability, malpractice, and business interruption insurance. Be aware that a few types of insurance (e.g., life insurance to secure a loan) may not qualify for deductions.

Taxes

Income taxes paid during the year to state, local, or foreign entities may be deductible against federal taxes. You may also be able to deduct other taxes, such as real estate, employment, or sales taxes.

Bank Fees and Interest Expense

Bank fees and interest on commercial loans or lines of credit may also be deductible for tax purposes with certain IRS stipulations. For most businesses, current guidance limits interest expense write-offs to the sum of business interest income, 30% of adjustable taxable income, and floor plan financing interest expense.

Depreciation

Costs related to assets with an extended life that depreciates over time, such as office equipment, furniture, or a company-owned vehicle, must be written off over a set number of years. The annual deductible amount is reported as a depreciation expense. Because the rules for depreciation can be complex, you may need to work with a tax professional to calculate depreciation deductions. You may also want to use a tax software program to calculate the allowable deduction each year and track the write-off in future tax reporting periods.

Auto Expenses

If you use a vehicle for your business, you can write off associated costs as a business expense. You may choose to write off actual expenses such as maintenance and gas, or you can use the standard mileage rate as determined each year by the IRS. For the 2024 tax year, this standard rate is 67 cents per mile.

Labor Expenses

Compensation paid to employees and contractors qualify as a tax write-off for business owners. This includes payment in the form of cash, property, or services. Examples include bonuses, awards, expense reimbursements, and other reasonable compensation for services performed. Self-employed individuals may not deduct their own salary as a business expense.

Education Expenses

Certain work-related education expenses may qualify for deductions in some cases. Education compensation offered as an employee benefit may also qualify as a tax-deductible labor expense.

Office Expenses

The costs of maintaining office space and storage are also deductible. This includes rent for office space and expenses associated with a home office. You can also write off expenses like telephone, internet, and utilities. If you work at home, you can write off a portion of your household bill for these items each month.

Business Travel and Meals

If you travel for work, you can write off some of the costs for tax purposes. If you combine personal and business travel, you should write off only the business-related costs.

When traveling for business, transportation, lodging, baggage, and vehicle costs are fully deductible, and business meals are 50% deductible in most cases.

Health Insurance

In most cases, the costs of providing health insurance, including group health insurance plans, for yourself and your employees can be written off for tax purposes. Small businesses that provide health care may also be eligible for an additional tax credit.

Conferences and Educational Seminars

Along with business travel, the costs of attending an industry conference are also deductible. Self-employed individuals who incur job-related educational costs may also take a deduction for tax purposes.

Which Expenses for Small Businesses Are Not Tax-Deductible?

The IRS may limit tax write-offs for some business expenses in certain scenarios. Take note of these exceptions and avoid including them on your tax return.

Certain Legal Costs, Fines, or Penalties

Legal costs for defending yourself when you've broken the law are not deductible. Any fines or penalties assessed by the government are also not deductible expenses.

Mileage Related to One's Normal Commute

Transportation costs for your daily commute are not considered a deductible expense and do not qualify for the standard mileage deduction. However, business travel outside of your regular commute is generally deductible.

Personal Expenses/Activities

Personal expenses are not deductible. If an expense is split between personal and business use, you must deduct only the portion of the costs related to your business. Additionally, if you partake in an activity without the intention of making a profit, you can't write off related expenses. This includes situations such as a sport, hobby, or recreational activity. In addition, the cost of any entertainment you may enjoy while on a business trip is not deductible.

Political Contributions

Contributions to support political candidates can't be written off for tax purposes.

How To File Tax Write-Offs

To file tax deductions for your business, you will need to start by saving receipts and documenting expenses throughout the year so you can support each deduction in an audit. When tax time rolls around, gather your financial documentation and group expenses into appropriate categories, such as advertising, office expenses, supplies, travel, etc.

Next, determine which form you need to file based on the type of business you operate:

• Schedule C (Form 1040): Sole proprietors file Schedule C along with their personal tax return to report any business-related expenses or deductions.
• Form 1120: Businesses structured as corporations should use Form 1120 (C-Corps) or 1120-S (S-Corps) to report income, losses, tax deductions, and credits.
• Form 1065: This form is used by partnerships that pass profits and losses on to their partners.
• Form 8829: If you operate your business out of your home, use Form 8829 to calculate allowable expenses you can deduct on Schedule C.
• Form 4562: Use this form to claim depreciation and amortization deductions for property assets, including business property, rental property, and vehicles.

If you have a complex situation or you aren't sure about specific deductions, check with your accountant or tax professional to ensure you claim all eligible deductions and follow IRS guidelines. Remember that some deductions, like vehicle expenses, may require additional documentation or specific calculation methods approved by the IRS.
