I tried a dozen of online tax calculators, but they all either focus on only one tax type (and miss important tax liabilities), or have a gazillion questions and take forever.
So, I made my own. It calculates all main federal taxes (income, medicare, medicaid, capital gain, ...) and combines everything into a single quick overview. Takes only a few secs to enter all relevant income details. Currently, no state/local taxes and no self-employment tax. If something would be better, I would love feedback!
