For Loans Only: The Tax Credit field allows for an input amount of a government tax credit amount to be plugged in under the Tax Credit Balance field. The Tax Credit field is under Pace Deal > Loans Section > Additional Parameters tab.
The assumption that this amount of money received from the government will be used to pay off some of the loan is made. Thus, a term is chosen, which is defined under the Tax Credit Interest Capitalized Term field. If the person who received the loan, pays the entire tax credit balance by that term - then it will be assumed that there was no interest that was accrued on the tax credit balance during that term. If they did not pay the entire tax credit balance by the end of the term - the entire accrued interest will be added to the balance.
Example:
A person takes out a $100,000$ loan, then receives a $40,000 tax credit, and the term is 18 months.

If the entire $40,000 is paid by the 18th period, the accrued interest on the tax credit balance is not added to the actual balance at period 18.

If the entire $40,000 is not paid - then the interest accrued on the tax credit balance will be added to my balance at period 18. Important to note, even if some of the $40,000 was paid, it will still accrue the entire interest for the entire $40,000.
