Frequently Asked Questions
Complete indexable directory of answers (5 questions)
Is my entire income taxed at my highest marginal bracket rate?
No. Progressive taxation means only the portion of income that exceeds a bracket limit is taxed at that rate. The income below that limit is taxed at lower rates.
How do tax deductions differ from tax credits?
Deductions reduce your taxable income base (e.g., subtracting $14,600 from earnings). Tax credits reduce your final tax bill dollar-for-dollar (e.g., subtracting $2,000 directly from taxes owed).
