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.
In general, charitable contributions are not allowed as a business expense on the Schedule C. However, if you made a payment to a charitable organization that was not for charity nor a gift, you may deduct the payment as an expense to the business. You may want to clarify or consider the terms of your donation. If your business received any benefit for the donation (ad space or marketing, for example) you may deduct the payment as an expense. Otherwise, your charitable gift/donation is not deductible under your business, but may be deducted on the Schedule A if you itemize your deductions for your personal tax return. You may want to review the IRS link below for clarification on this rule.
