Final answer:
Personal exemptions for income tax are determined by the number of dependents and filing status, and vary based on individual circumstances.
Step-by-step explanation:
When arriving at personal exemptions for income tax, the rules are determined by the number of dependents and filing status. This means that the more dependents a taxpayer has, the higher their personal exemption will be.
For example, a single person with no dependents will have a lower personal exemption compared to a married couple with children.
These exemptions are not fixed for everyone, but instead vary based on individual circumstances and the taxpayer's specific filing status and number of dependents.
