Key IRS Business Deductions to Remember in 2025
Below are the major deductions of all businesses must be aware of:
1. Standard Deduction Increase
There has been a notable increase in the standard tax rates. They are:
- Single individuals: $15,000 (an increase of $400)
- Joint filing as married: $30,000 (increased by $800)
- Head of household: $22,500 (increase of $600)
True, the majority of companies would typically file their taxes independently of their personal tax returns, but what is noteworthy is that these increases do have a significant impact on sole proprietors and single-member LLCs. These specific types of business entities are forced to report their business income on their tax returns.
2. The Section 179 Deduction
Section 179 is a very powerful tax incentive because it lets businesses write off the entire cost of equipment and software allowed under the section if it is put into use in the taxable year. This means, instead of going through the painstaking method of amortizing the cost over a period and getting a delayed tax relief, businesses immediately get the financial advantage.
- 2025 cap: $1,250,000 (phased down from $3,130,000 of buys)
- Bonus depreciation is 40% for qualifying property after the Section 179 limits have been reached and depleted.
- Eligible property: Used and new equipment, off-the-shelf computer programs, special vehicles (with special exceptions for trucks and sport utility vehicles)
- Business-use requirement: Property must be utilized more than 50% for business
This particular deduction is highly applicable to businesses that are thinking of making large capital expenditures, as well as businesses that are seeking means to enhance their cash flow situation.
3. Business Mileage Deduction
Here is everything you need to know about business mileage deduction:
- 2025 standard mileage rate: 70 cents a mile for business use (up from 67 cents in 2024).
- Applies to cars, vans, trucks, and panel trucks, including electric and hybrid cars.
- The required mileage reports must be kept to support claims.
The rise in this specific rate means that more savings opportunities for companies that greatly depend on the utilization of cars in their businesses will be there.
4. Home Office Deduction
The specific requirements for a home office deduction are mentioned below:
- Eligibility: The approved area should be used solely and exclusively as the principal venue where business operations are carried out.

- Limitations: This is available only to the self-employed as well as to small business owners. It excludes employees who are working remotely for large organizations.
Home office deduction continues to be such a convenient and effective method of lessening taxable income, particularly among those solopreneurs and business companies who have remote work as their primary working arrangement.
5. Qualified Business Income (QBI) deduction
Various pass-through business entities, such as sole proprietorships, partnerships, S corporations, and certain LLCs, are eligible to claim a deduction for up to 20% of their qualified business income to reduce taxable income.
- Income limits: The right to claim deductions falls progressively for high income earners and for certain service business types.

Tax Strategy Recommendations for 2025
The recommendations and advice can be followed by the businesses to handle the updated tax deductions in a better way.
- Plan Equipment Purchases: Take advantage of the increased Section 179 limit and bonus depreciation to maximize deductions in profitable years.
