Worked Example

Suppose you earned $75,000 in 2018, claimed the standard deduction of $12,000, and had no other deductions. Your withheld tax was $10,000.

  1. Taxable Income = $75,000 - $12,000 = $63,000
  2. Federal Income Tax:
    • $9,700 × 10% = $970
    • $29,775 × 12% = $3,573
    • $33,525 × 22% = $7,376
    • Total = $970 + $3,573 + $7,376 = $11,919
  3. Net Tax = $11,919 - $0 (no credits) = $11,919
  4. Refund/Payment = $11,919 - $10,000 = $1,919 refund

You would receive a $1,919 refund from the IRS.
