Show all hidden content
Overview
The information entered in the MortgInt screen transfers to Schedule A. Make sure the information you enter in this input screen doesn't duplicate deductions that you've entered elsewhere.
Home Mortgage Interest Limitations
If the taxpayer's mortgage interest deduction must be limited due to the amount or nature of the loans, enter the mortgage information in this section. UltraTax CS uses the information entered to complete the Home Mortgage Limitation Worksheet A and the Mixed Use Mortgage Worksheets. With regard to these worksheets, please note the following:
- UltraTax CS produces 1 Worksheet A and an unlimited number of Mixed Use Mortgage Worksheets. A mixed use mortgage summary reporting the average balance of all loans will print on the last unit of the Mixed Use Mortgage Worksheet.noteThe Mixed Use Mortgage Worksheets will calculate the average balance on all loans regardless of whether the loan meets the definition of a mixed use mortgage.
- The Mixed Use Mortgage Worksheets calculate the average balance for each type of debt by determining the balance for each category of debt for each month the loan was outstanding, adding the monthly balances together, and dividing by 12. The calculated average balance amounts transfer from the Mixed Use Mortgage Worksheets to Home Mortgage Limitation Worksheet A.
- Additional amounts borrowed against existing loans should be entered in a separate unit of the MortgInt screen.
note
You can enter the interest paid for a particular mortgage in this section or in the
Home mortgage interest: From Form 1098
field in the Interest Expenses section of the A screen, but you shouldn't enter the information in both places for the same mortgage.Loan origination date
Enter the date the loan was taken out. Per IRS Publication 936, “The date you take out your mortgage is the day the loan proceeds are disbursed. This is generally the closing date. You can treat the day you apply in writing for your mortgage as the date you take it out. However, this applies only if you receive the loan proceeds within a reasonable time (such as within 30 days) after your application is approved.”
Whether the loan is the initial/original acquisition loan, a refinanced loan, a home equity loan, etc., use the date the applicable loan was taken out. If more than 1 loan exists for the same home, complete a separate MortgInt screen for each loan secured by the residence.
Fair market value of home(s)
Enter the fair market value of the qualified homes as of the date the debt was last secured to calculate line 7 of Worksheet A. If you leave this field blank, UltraTax CS assumes the fair market value is 0.

No. of months loan was outstanding in
2025
