The one-sentence version
A tax deduction reduces the amount of income that gets taxed. A tax credit reduces the amount of tax you owe.
Both save you money — but they work at different points in the calculation, and credits are almost always more valuable dollar-for-dollar.
A real example with numbers
Let's say your taxable income is $60,000 and you're in the 22% tax bracket. You have two choices: a $1,000 tax deduction or a $1,000 tax credit.
A tax credit saves you its face value. A tax deduction saves you its face value × your tax rate. In the 22% bracket, a $1,000 deduction saves $220. A $1,000 credit saves $1,000. Always prioritize credits over deductions.
The three types of tax credits
Not all tax credits work the same way. Understanding the three types helps you know what to expect when you file:
Refundable
Can reduce your tax bill below zero. You receive the excess as a cash refund — even if you owed no tax at all.
Partially Refundable
Has both a refundable and non-refundable portion. Part of it can generate a refund; the rest only reduces tax to zero.
Non-Refundable
Can reduce your tax bill to zero, but cannot generate a refund. Only useful if you actually owe taxes.
Common deductions — and what they're actually worth
Deductions are valuable, but their worth depends on your tax bracket. Here's a quick guide to the most common deductions for Chinese families and what they actually save at common tax rates:
| Deduction | Who qualifies | Savings at 12% | Savings at 22% |
|---|---|---|---|
| Standard deduction ($14,600 single) | Everyone — no tracking needed | $1,752 | $3,212 |
| Student loan interest (up to $2,500) | Paid student loan interest, income under limit | $300 | $550 |
| IRA contribution (up to $7,000) | Earned income, under age 50, meets income limits | $840 | $1,540 |
| Self-employed health insurance | Self-employed, paid your own premiums | Varies | Varies |
| Home office (if self-employed) | Dedicated workspace used for business | Varies | Varies |
| Business expenses (Schedule C) | Self-employed — all ordinary and necessary expenses | Varies | Varies |

How they work together: the full picture
Credits and deductions don't compete — they work in sequence. Here's the order in which everything happens on your tax return:
Now that you understand the difference, here's how to apply it: (1) Always claim every credit you qualify for — they're more valuable than deductions. (2) Take above-the-line deductions (IRA, student loan interest) before calculating your AGI — they unlock other benefits. (3) Compare standard vs. itemized deduction using tax software — let it calculate both and choose the larger one. (4) Don't miss refundable credits just because you don't think you owe taxes — the EITC and Child Tax Credit can generate real cash refunds.
