Life is like a box of chocolates. A metaphor is also a figurative comparison between two things, but does not use like or as - ex. All the world's a stage. Keep in mind that a simile is a type of metaphor, so all similes are technically metaphors.
For most people, the limits on charitable contributions don't apply. Only if you contribute more than 20% of your adjusted gross income to charity is it necessary to be concerned about donation limits. If the contribution is made to a public charity, the deduction is limited to 50% of your contribution base. For example, if you have an adjusted gross income of $100,000, your deduction limit for that year is $50,000. The rules on 20% limits and 30% limits are way too complicated to delve into in this space.
The tax man may look at your income and giving patterns and decide you're either not reporting all your income or claim you're donating more than you really are. The IRS limits your donations to 50 percent of your adjusted gross income, and different types of gifts require different forms. Make sure you get receipts for every donation you claim. While you are not required to attach receipts to your tax return for all donations, you should keep them on hand in the event that you are audited or investigated.
