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.
A tax rate is the percentage of the value of property or income to be paid to the government as a tax. For example, if you earn $50,000 in salary for one year, and the applicable income tax rate is 20%, then you must pay $10,000 in taxes, which is 20% of the value of your annual income.
