How much can Leah contribute to her IRA for the year 2023?

For the year 2023, the standard contribution limit for individual retirement accounts (IRAs) is $6,500 for individuals under the age of 50. However, individuals aged 50 and above have the opportunity to make an additional catch-up contribution, which is an extra $1,000. This means that those eligible can contribute a total of $7,500 to their IRA.

Given this information, if Leah is 50 years old or older, she can contribute the higher amount of $7,500 to her IRA for the year 2023. This option takes into account both the standard limit and the additional catch-up contribution allowed for those who are older, making it the correct answer.
