Essential Tax Breaks for Small Businesses in 2025

• Section 179 Deduction:
  Businesses can deduct the full cost of qualifying equipment or software purchased in 2025 instead of depreciating it over time. This is particularly useful for businesses making significant investments in equipment or technology.
• Qualified Business Income (QBI) Deduction:
  Eligible small businesses can deduct up to 20% of their qualified business income, reducing taxable income for pass-through entities like LLCs, S Corporations, and sole proprietorships. Eligible taxpayers can claim the deduction for tax years beginning after December 31, 2017, and ending on or before December 31, 2025.
• Work Opportunity Tax Credit (WOTC):
  A credit available to employers who hire individuals from certain target groups, such as veterans or long-term unemployed workers.
• Home Office Deduction:
  Small business owners working from home can deduct a portion of their mortgage, rent, utilities, or other home-related expenses if a dedicated space is used exclusively for business.
• Energy-Efficient Tax Credits:
  Small businesses that invest in energy-efficient building improvements or equipment may qualify for credits under programs like the Energy Efficient Commercial Buildings Deduction.
• Research and Development (R&D) Tax Credit:
  Businesses investing in product development, software improvements, or innovative processes can benefit from this credit, which offsets costs associated with innovation.
