Does my net paycheck decrease as the year goes on due to tax brackets filling up?
No, you will (generally speaking) not see a decrease in your net earnings from crossing a tax bracket: This means that your highest marginal rate (the top bracket you fall into) only applies to the portion of your income that is in that bracket, not your total income. This helps ensure that your total tax burden does not increase measurably from crossing a tax bracket. Be aware that you can still see measurable changes in your total taxes due if increases in income make you no longer eligible for certain deductions and/or benefits that were otherwise reducing your tax burden, but this is not the same as how changes in your highest marginal rate affect your overall average tax rate. Note that when you see a rate table such as the one on efile.com's federal income tax rates page or on Wikipedia's Income tax in the United States page, the rates listed are for each segment of income, not for your overall income: In other words the 15% rate below (for 2014, filing single) only applies to the portion of your income falling between the listed numbers, not to income below it or above it: that would be calculated under the respective rates given. You can use the i1040tt tax tables to gain a sense of how this works in practice: (The linked resource is for 2014 taxes) The threshold in 2014 for the 25% rate vs 15% was $36,900. Using the linked table, if you were single and made between 36,850 and 36,900 in gross income, your tax liability before other considerations was $5,078. If you made between 36,900 and 36,950, your base tax liability was $5,088.
