Step-by-step explanation:
The sentence "Many people don't understand the complexities of deductions and withholdings, so they hire someone to do their taxes" contains jargon related to the field of accounting or taxation, which is a specialized vocabulary understood by professionals in that field. Jargon includes technical expressions that are precise and efficient for communication among experts but can be confusing to those who are not well-versed in the particular subject matter. In the context of taxes, deductions refer to certain expenses that can be subtracted from a taxpayer’s gross income to reduce taxable income, while withholdings pertain to the portion of an employee’s wages that is not included in their paycheck because it is sent directly to the government as partial payment of their income tax liability. When writing for a general audience, it's crucial to avoid such specialized language or explain it clearly to ensure understanding.
