Final answer:
The court is likely to determine that Max Tax Service committing a material breach by only completing half of Rebecca's taxes by the due date, which potentially absolves Rebecca from the obligation to pay for the incomplete service.
Step-by-step explanation:
When evaluating whether Max Tax Service's failure to complete Rebecca's tax return is a material breach, it's crucial to understand the nature of the contract and the consequences of the unfinished work. A material breach occurs when the failure to perform a contract is so substantial that it defeats the purpose of the agreement, giving the non-breaching party the right to terminate the contract and sue for damages. In this case, completing only half of Rebecca's home business taxes could be considered a material breach because the service is not fully provided by the critical deadline. Therefore, the court will most likely decide that this is a material breach, as the taxes were not fully prepared by the due date of April 15th, and Rebecca may not be obligated to pay Max anything.
