Just what can you write off for your business....Common Business Expenses for the Business Owner and Highlights of the Federal/State Differences
Source: California Franchise Tax Board
We detail the most common business expenses in this publication. Use this publication together with the federal publications we reference here. Although there are many forms of business ownership that have business expenses, this publication focuses on sole proprietorships. Business expense deductions allowed to be taken by other business entities may be subject to different rules.
Common Business Expenses
Whether you are forming a new business or you are a current business owner, claiming all the expenses you are entitled to makes smart business sense. In addition, deducting business expenses can potentially lower the overall tax liability of your business. Business expenses are the costs of carrying on a trade or business, and they are usually deductible if the business is operated to make a profit.
The Franchise Tax Board (FTB) generally follows federal law on many common business expenses. The attached comparison chart details some common business expenses that may be deductible for income tax purposes. The chart also shows how the Internal Revenue Service (IRS) and FTB treat each type of expense.
The IRS allows a business expense deduction if the expense is both ordinary and necessary. An ordinary expense is defined as an expense that is “common and accepted” in your trade or business. A necessary expense is defined as an expense that is “helpful and appropriate” for your trade or business. An expense does not have to be indispensable to be considered necessary.
Your business may also generate expenses that tie into the cost of goods sold if you manufacture a product or if you have capital expenses for fixed assets you purchased. This publication’s focus is on the common business expenses that may be deductible for income tax purposes.
As a general rule, a taxpayer must maintain adequate records or other sufficient evidence to substantiate expenses claimed. Additional evidence is required for some expenditures or use, such as, travel, entertainment, gifts, and auto expenses.
Additional Information – Common Business Deductions
Automobile Expenses
We follow the federal guidelines on automobile expenses. A business deduction is only allowed when you use your car for business purposes. Deductible car expenses may include: travel from one workplace to another, business trips to visit customers/attend business meetings away from your regular workplace, or travel to temporary workplaces.
We allow two methods to determine your business car expenses:
Actual expenses – Car operating expenses (e.g., gas, oil, repairs, license fees, insurance, depreciation, etc.) for the entire year multiplied by the percentage of time you used the car for business purposes.
Standard mileage rate – A more simplified method in which you multiply the business miles and the applicable published federal mileage rate.
We require that you keep adequate records showing the date, amount, place, and essential character of the expense to substantiate your deduction(s).
Business Start-up Costs
As a new business, you can generally deduct up to $5,000* of start-up expenses (e.g., salaries, marketing, market analysis, etc.) and $5,000* of organizational costs (e.g., legal services, fees paid to the state to incorporate).
Home Office Expenses
In order to claim a home office expense, you must ensure that the area of your home is used regularly and exclusively for business purposes. If this test is met, then you would claim any direct expenses that are used exclusively for the business (e.g., computer, supplies, etc.). For indirect expenses, you would compute the percentage of your home that is being used for business purposes and apply the percentage against any indirect expenses (e.g., utilities, insurance, and depreciation). IRS Publication 587, Business Use of Your Home, has more information about home offices.
Travel, Meals, and Entertainment Expenses
First, the expense must be considered ordinary and necessary for your business. Secondly, the expense must be primarily for business purposes (e.g., travel to a new client’s office). The IRS provides detailed guidance about these types of expenses in IRS Publication 463, Travel, Entertainment, Gift, and Car Expenses. We follow IRS guidelines.
Bonus Depreciation
In California, you can elect to deduct up to $25,000* of the costs incurred during the year for the acquisition of personal property used in your business.
Client Gifts
We allow a deduction of up to $25 for each recipient of a gift.
Employee Pay
You can generally deduct the pay you give your employees for the services they perform for your business.
