Color of Diff Oil. I replaced my differential fluid at 60k miles, I'm now at 71k and today when getting my oil changed the guy showed me the oil and it was dark brown in the rear while the front was still the clearish-yellow like it was when I put them in.
The average tax rate is the tax rate you pay when you add all sources of taxable income and divide that number into the amount of taxes you owe. In other words, you can calculate your average tax rate by dividing your total tax obligation by your total taxable income.
But nationally, the tax code is still broadly progressive. The more your make, the more taxes you pay as a percentage of your income. According to new data from the IRS, people who make $1 million or more had an average tax rate of 20.4 percent in 2010. Tax filers who earned $30,000 to $50,000 paid an average rate of 4.8 percent, while those who made between $50,000 and $100,000 paid 7.7 percent.
