Whether you run a home-based business, e-commerce store, service company, or startup, this guide will help you navigate business taxes with confidence.
1. Understanding Tax Deductions vs. Tax Credits
Before diving into the exact benefits available in 2025, it’s important to understand the difference:
Tax Deductions
Deductions reduce your taxable income.
For example, if your business earns $80,000 and you claim $20,000 in deductions, you pay taxes on $60,000.
Tax Credits
Credits reduce your actual tax bill — often dollar for dollar.
If you owe $5,000 in taxes and qualify for a $1,000 credit, your total tax owed becomes $4,000.
Both are important, but credits typically provide bigger savings.
