Final answer:
A married couple with high income is classified as a high-earning household in the field of Business.
Step-by-step explanation:
The subject of this question is Business.
A married couple who earned income that exceeded $300,000 in each of the prior two years and reasonably expects the same for the current year falls under the category of high-earning households.
These households have a higher income level compared to the average household income and may have different tax rates or requirements.
For example, in the United States, the tax rate for high-income earners can be higher than the tax rate for individuals with lower income levels.
Understanding the tax rates, deductions, and other aspects of the tax system can help the couple plan their finances effectively.
