Tax season is approaching, and smart tax planning can save you thousands of dollars. Whether you’re a W-2 employee, freelancer, or small business owner, these tax optimization strategies will help you legally minimize your tax burden and keep more of your hard-earned money.
Understanding Tax Optimization vs. Tax Evasion#
Tax optimization (or tax planning) involves using legal strategies to minimize your tax liability. This is completely different from tax evasion, which is illegal. The IRS expects you to pay the least amount of tax legally required – not a penny more.
