Tax Credit vs. Tax Deduction là gì?

The difference is direct reduction vs. indirect reduction. A $1,000 tax credit saves you exactly $1,000 in taxes. A $1,000 tax deduction saves you $1,000 × your marginal tax rate — so at a 24% bracket, a $1,000 deduction saves you only $240. Credits can be refundable (you receive the excess as a refund even if your tax liability is zero — e.g., Earned Income Tax Credit, portions of the Child Tax Credit) or non-refundable (can only reduce your liability to zero — e.g., Lifetime Learning Credit, Foreign Tax Credit). Common business tax credits include the R&D Tax Credit (IRC §41), Work Opportunity Tax Credit (WOTC), Small Business Health Care Tax Credit, and the Employee Retention Credit (ERC). Common deductions include the standard deduction ($14,600 single / $29,200 married filing jointly for 2024), business expenses (§162), home office deduction, and the Qualified Business Income deduction (§199A, up to 20% of QBI for pass-through entities). Tax planning strategy often involves maximizing credits first (since they're dollar-for-dollar), then optimizing deductions. Some provisions offer a choice — for example, the foreign tax paid can be claimed as either a credit or a deduction.

Many taxpayers and business owners confuse credits and deductions, leading to poor financial decisions. For example, a business owner might chase a deduction that saves them 24 cents per dollar while overlooking a credit worth the full dollar. A tax advisor can identify all credits and deductions you're eligible for — many of which (like the R&D credit for startups) are routinely missed — and structure your filings to minimize total tax liability.
