Final answer:
The correct option is C. To record the amount of transfer tax a Delaware seller will pay if the buyer is an out-of-state entity.
Step-by-step explanation:
A Delaware licensee's seller clients complete tax form 5403 primarily to record the transfer tax that a Delaware seller must pay if the buyer is an out-of-state entity. This form is not about receiving tax credits for losses nor about rebates for real estate commissions; instead, it's related to the taxation process when a real estate transaction occurs.
The requirement to complete this form demonstrates the seller's financial responsibility in the context of the transfer and is a component of the state's fiscal policy relating to real estate transactions.
