Update Instructions


For more detailed information please see our deployment documentation: V3 Deployment Information

  1. Download the latest update package for your calculators from your download site, found on your update e-mail notice.

  2. Execute the KJEUpdate.exe file from your download. This is a self-extracting zip file. (Or unzip the KJEUpdate.zip file if you are using a non-windows platform.) If you see a warning message, you can safely continue. When prompted for a directory, you may use the default or enter your own. It is recommended that you extract the update to a new directory and then move the required files to your production or staging environment. One directory will be created with no subdirectories.

  3. Replace all files provided in update package. The update package includes all JS files and CSS files that are required to update the content of your calculators. IMPORTANT! The update package does not contain any HTML files or the KJESiteSpecific.js or KJESiteSpecific.css files. These files are not required for an upgrade, and replacing them may result in overwriting custom changes for your website installation. If you use the full installation package and have changed the file KJESiteSpecific.js or KJESiteSpecific.css files do not replace them.

When you test the new version of the calculators, make sure that the browser you are using uses the new files instead of any it may have in its cache. You may need to clear the browser's cache manually to ensure the new versions are loaded.

    • Calculate your total taxable income without long-term capital gains.
    • Use this amount to determine the rate for your long-term gain, up to the top of the bracket.
    • The portion of your long-term capital gain that exceeds a bracket will be taxed at the next higher rate.
    • This calculator assumes that none of your long-term capital gains come from collectibles, section 1202 gains or un-recaptured 1250 gains. These types of capital gains are taxed at 28%, 28% and 25% respectively (unless your ordinary income tax bracket is a lower rate).

    Wages, salaries, tips, etc.

    This is your total taxable income for the year after deductions for retirement contributions such as 401(k)s, IRAs, etc. This calculator is designed to work primarily with earned income taxed at ordinary income tax rates. It is not designed to calculate taxes from capital gains, business income or passive income sources.

    Income Tax Rate Definitions (this appears on the report and main calculator)

    Income Tax Rates
    Average tax rateThis is your total income divided by your total Federal tax. The average tax rate is almost always lower, sometimes by a wide margin, than your income tax bracket or marginal tax rate.
    Income tax bracketThis is the highest Federal income tax bracket used in calculating your total Federal tax. This is calculated by looking up the highest Federal income tax bracket that includes your taxable income.
    Marginal tax rateThis is the percentage paid in Federal taxes on additional income. To determine your marginal tax rate, the tool recalculates your total Federal income tax using your current income plus an additional income amount. The additional income amount is $1,000 for incomes under $100,000 and $10,000 for incomes over $100,000. We then divide the difference between your original Federal tax and the recalculated Federal tax by the amount of additional income. Your marginal tax rate captures the effect of additional income taxed in higher income brackets and the phase-out of deductions and credits. It will never be lower than your current tax bracket.

    Dependents qualifying for child tax credit

    Enter the number of dependent children that qualify for the child tax credit. To qualify, a child must be under age 17 at the end of the year. They must be either your child, one of your siblings or your foster child or a child of any of them (for example your grandchild). In addition, they must have lived with you for more than half of the year, not provide more than half of their own support and must be claimed as a dependent on your tax return. In 2024, for each qualifying child you can receive up to a $2,000 tax credit. While the same as the prior year, this amount is significantly lower than 2021. In 2021, the tax credit was up to a $3,600 per child under age six and up to $3,000 per child age six to 17.
