Start Here: Finding Your Effective Rate
If you are a standard W-2 employee, run your salary through the Federal Income Tax Bracket Calculator. It is crucial to understand the difference between your "Marginal" top bracket and your actual "Effective" blended tax rate. This prevents panic regarding whether a raise will secretly "lower" your take-home pay (which is mathematically impossible).
If you are a freelancer or contractor, you must use the Self-Employment FICA Calculator. 1099 workers are on the hook for both the employee and employer portions of Social Security and Medicare. Running these numbers ensures you are structurally saving enough cash for brutal quarterly tax filings.
