Tax Deduction

Tax Deduction — what it means, how it works, and a real example, explained without the jargon.

What is Tax Deduction?

A deduction lowers the income you're taxed on. Its value depends on your bracket — it saves you the rate, not the full amount.

How it works

You subtract deductions before the brackets apply, so a deduction shrinks taxable income. A dollar deducted saves you a dollar times your marginal rate. That's why the same deduction is worth more to a high earner than a low one.

A quick example

A $5,000 deduction saves $1,100 for someone in the 22% bracket but $1,850 for someone in the 37% bracket — same deduction, different value.

What people get wrong

"Write it off" doesn't mean it's free. A $100 deductible expense might save you $22 in tax — you still spent $78. Deductions soften real costs; they don't erase them.
