Frequently Asked Questions
What is the difference between marginal and effective tax rates?
Your marginal rate is the rate on your last dollar of income. Your effective rate is the average across all income. Understanding this helps assess the true tax impact of additional income.
How do tax brackets work?
Tax brackets are ranges of income taxed at specific rates. Only income within each bracket is taxed at that rate. Moving into a higher bracket does not raise your entire tax rate.
What is the difference between a tax deduction and a tax credit?
A deduction reduces taxable income (saving at your marginal rate). A credit directly reduces your tax bill dollar for dollar. Credits are more valuable.
How do I estimate quarterly tax payments?
Estimate annual tax liability and divide by four. Due dates: April 15, June 15, September 15, January 15. Pay at least 90% of current year tax or 100% of prior year to avoid penalties.
