Home office deduction

If you use part of your home exclusively and regularly for business, you may qualify for the home office deduction. This is one of the most valuable deductions for Florida business owners who work from home.

Simplified method: Deduct $5 per square foot of home office space, up to 300 square feet. Maximum deduction: $1,500. No complex calculations required.

Regular method: Calculate the percentage of your home used for business (office square footage divided by total home square footage). Deduct that percentage of actual home expenses: mortgage interest or rent, utilities, insurance, repairs, and depreciation.

Vehicle expenses

If you use your vehicle for business, you can deduct the costs. You have two methods:

Standard mileage rate: For 2026, the IRS standard mileage rate is 70 cents per mile for business use. Simply track your business miles and multiply. This method includes gas, maintenance, insurance, and depreciation.

Actual expense method: Track all vehicle expenses (gas, oil, repairs, insurance, tires, registration fees, lease payments, depreciation) and deduct the business percentage based on miles driven for business vs. total miles.

You must choose the method in the first year you use the vehicle for business. After that, you can switch between methods in later years if you use the standard rate initially.

Equipment, supplies, and software

You can deduct the cost of tangible items you buy for your business. Here is how different items are treated:

Supplies under $2,500: Office supplies, postage, printer paper, cleaning supplies, and other consumables are fully deductible in the year purchased.

Equipment and software: Computers, printers, furniture, machinery, and software can be deducted under Section 179 (full cost in year one, up to a limit) or bonus depreciation. For 2026, Section 179 allows up to $1,220,000 in qualifying property.

Subscriptions and SaaS: Software subscriptions, cloud services, professional memberships, and trade publications are fully deductible as ordinary business expenses.

Startup costs and professional fees

Before your business officially opens, you may incur startup costs. The IRS allows you to deduct up to $5,000 in startup costs and $5,000 in organizational costs in your first year of business.

Startup costs include: Market research, advertising before opening, training, travel for finding suppliers or customers, and professional fees for business planning.

Organizational costs (LLC/corporation): Legal fees for drafting operating agreements, state filing fees, and accounting fees related to business formation.

Ongoing professional fees: Fees paid to accountants, bookkeepers, lawyers, and consultants for business services are fully deductible.

Insurance and employee benefits

Business insurance premiums and certain employee benefit costs are deductible. For Florida business owners, these are common deductions:

Health insurance premiums: Self-employed individuals can deduct 100% of health insurance premiums for themselves, their spouse, and dependents. This deduction is taken on Schedule 1 (Form 1040) and does not require itemizing.

Business insurance: General liability, professional liability (errors and omissions), property insurance, workers’ compensation, and business interruption insurance premiums are all deductible.

Retirement plans: Contributions to SEP-IRA (up to 25% of compensation, max $66,000 for 2026), SIMPLE IRA, or Solo 401(k) are deductible and reduce your taxable income.

Other benefits: If you have employees, group term life insurance (up to $50,000 per employee), dependent care assistance, and education assistance programs are deductible within IRS limits.

Other common deductions for Florida businesses

Here are additional deductions Florida business owners should not overlook:

Rent and utilities: If you lease a separate business space, rent, electric, water, internet, and phone are deductible. If you work from home, use the home office deduction instead.

Business meals: Meals with clients, prospects, or business associates are 50% deductible. Keep records of who you met with and the business purpose.

Travel: Airfare, hotels, rental cars, and 50% of meals while traveling for business are deductible. The trip must be primarily for business purposes.

Bank and credit card fees: Business bank account fees, credit card processing fees, and interest on business credit cards are deductible.

Advertising and marketing: Website hosting, domain names, social media advertising, Google Ads, business cards, signage, and promotional materials are fully deductible.

Education: Courses, workshops, seminars, and books that maintain or improve skills required for your current business are deductible.
