IRS Business Expense Rules 2025: Key Updates for Small Businesses
The IRS business expense rules 2025 introduce important updates for small businesses, including new deduction limits, mileage rates, and depreciation rules. Knowing these changes helps you plan expenses and stay fully compliant with IRS regulations this year.
Each year, the IRS updates its guidelines on deductible business expenses, and 2025 brings a few important adjustments that small business owners should note. From mileage and meals to depreciation and vehicle value limits, understanding these updates helps you plan your deductions correctly and avoid costly mistakes.
1. Standard Mileage Rates for 2025
One of the most significant annual updates comes with the IRS standard mileage rates. According to IRS Notice 2025-5, the rate for business use of a vehicle is 70 cents per mile starting January 1, 2025. This rate reflects average operating costs, including fuel, maintenance, and depreciation.
The rate for medical or moving purposes remains 21 cents per mile, while the charitable rate stays at 14 cents per mile. Employers who reimburse mileage or provide vehicles for employee use should ensure they are using these updated figures.
2. Depreciation and Vehicle Value Limits
For 2025, the IRS set the depreciation component within the standard mileage rate at 33 cents per mile. This figure represents the portion of each mile that accounts for wear and tear on your vehicle.
Additionally, the maximum vehicle value that qualifies for the Fixed and Variable Rate (FAVR) plan and certain employer valuation methods is $61,200. Vehicles above this value require a different calculation method under IRS rules.
These updates align with the “IRS 2025 Mileage Rates and Vehicle Limits.”

3. Meals and Entertainment Expenses
Meal deductions remain at 50% of qualifying expenses for 2025. To qualify, the meal must be directly related to business activity and properly documented with date, purpose, and attendees. Entertainment expenses, such as event tickets, remain non-deductible unless they meet specific business criteria outlined in IRS regulations.

4. Office, Equipment, and Technology Costs
Small business owners can continue to deduct ordinary and necessary expenses used to run their business, such as office supplies, technology, and equipment. Under Section 179, many assets can be expensed immediately rather than depreciated over several years, subject to IRS limits.
Always check the latest Section 179 limits each year, as these amounts are adjusted for inflation and can significantly affect your tax strategy.
5. Recordkeeping and Documentation
The IRS emphasizes accurate and timely recordkeeping. Keep receipts, digital copies, and mileage logs for all deductible expenses. Using accounting software or cloud storage is highly recommended for maintaining compliance and simplifying tax filing.
6. Planning Ahead
It’s wise to review your expense-tracking process early in the year. Consistent, detailed records not only make filing easier but also help you identify patterns that could reduce future costs. Working with a qualified tax advisor can ensure you’re applying the rules correctly and taking full advantage of available deductions.
Bottom Line
The IRS updates business expense rules annually to reflect inflation and economic conditions. Staying informed about these changes — especially mileage rates, depreciation limits, and documentation standards — can save your small business both time and money.
