If a home mortgage includes a portion of the funds that were used to pay expenses for other than for the home or improvements to that home, or if the average monthly sum of all mortgages exceeds a limit, not all the interest is deductible. This may occur for a second or a refinanced mortgage, especially during first few years of the mortgage. Such other expenses might be to pay credit card debt, medical expenses, vacation trips or a new car, as examples. This worksheet helps determine how much of the interest paid on the mortgage is deductible.

TaxSlayer^® provides no assistance in determining the portion of income (other than W-2s), adjustments and deductions available for a part-year resident. This worksheet is tailored to Colorado state tax returns and provides TaxSlayer totals for input to the "Income Subject to Tax" section.

Railroad retirement Tier 1 and/or Tier 2 amounts are not handled correctly by TaxSlayer^® on Colorado state tax returns. One or both are included in the retirement exclusion which is limited to 20K/24K and should not be because RRB benefits are not taxable and have their own exclusion line. This worksheet determines the amounts that should be removed from the pension exclusion and calculates the amount that should be added as the RRB benefits line on the State Return section of TaxSlayer. Although designed specifically for Colorado it may work for other states if the problem is the same.

Can't find the latest version of the Earned Income Tax Credit plots? This tool presents a graphical presentation of the amount of credit available for various tax credits vs AGI. For simplicity, it assumes all income is earned income and provides options for comparing tax years, filing status and number of children (or students for education credits) or seeing how various credits kick in for a particular year and filing status. The effect of combinations of credits is not considered but will, of course, change the results in a real tax return so you can't just add them together.

TaxSlayer^® determines the taxable amount of the state tax refund based on sales tax and comparison with the standard deduction. If the taxpayer made estimated payments to the state or had negative taxable income (may show as 0), there may be a better solution. This calculator includes those other comparisons so you don't have to do the math. Taxability of other refunds, such as medical repayments, are also included and can be quite complex when considered when state tax refund is also present.
