In the given options, the example of a tax you must pay is Medicare. Medicare is a federal health insurance program in the United States that provides coverage for individuals who are 65 and older, as well as certain younger people with disabilities. It is funded through payroll taxes, premiums, and general revenue.
Here's a breakdown of why the other options are not examples of taxes you must pay:
1. Rental payment: This is a payment made to a landlord in exchange for the use of a property. It is not a tax but rather a fee for renting a space.
2. Bounced check: When a check is bounced, it means that there were insufficient funds in the account to cover the payment. While there may be fees associated with bounced checks, it is not a tax but a penalty for insufficient funds.
3. Late Fee: A late fee is a penalty charged for not making a payment on time. It is not a tax but an additional charge imposed by a creditor or service provider for missing a payment deadline.
In summary, out of the options provided, Medicare is the example of a tax you must pay, while the other options are not taxes but rather rental payments, bounced check fees, and late fees.
