As you rush to get your charitable donations in before Dec. 31, don't forget to think about a giving plan for 2018. While it might sound like just one more thing to add to your to-do list, experts say there are good reasons for it. For one, taking time to evaluate your giving is a good gut-check that you can afford to part with that cash. It also can help alleviate pressure — whether self-imposed or external — to give. "If you give to everyone who asks you to give, there's no real value in that," said Edward Kramer, a certified financial planner with Abacus Planning Group in Columbia, South Carolina. "If your heart isn't in it, you really miss out on the joy of giving. You're only giving because someone asked."

By and large, Americans are a charitable bunch. In 2016, total donations reached $390 billion, with the bulk coming from individuals ($282 billion), according to Giving USA. That's more than three times the $77.83 billion given by corporations ($18.55 billion), and it exceeds foundations ($59.28 billion). The top three categories getting most of donations last year were religion ($122.94 billion), education ($59.77 billion) and human services ($46.8 billion). Despite individuals' generosity, giving can be a source of stress for donors. Financial advisors say some clients simply struggle to say no, and others face pressure from the organization itself.

For many people, requests for donations come in the form of mailed solicitations or phone calls. Some wealthy donors are approached in a more personal way, like being invited to meet for dinner to hear about a particular fundraising effort. If you're among those who feel pressured, the best defense is a good offense — that is, a predetermined annual giving plan that you evaluate once a year. The first step in making a 2018 giving plan is to reconnect with why you make charitable donations in the first place. "When we make financial donations out of habit or pressure, our heart is not tied to the donation," Kramer said. "So, why do you want to make a donation?" Once you make that determination, figuring out how much you plan to give can become more fulfilling. To arrive at that number, take a look at your past level of giving and your current financial means.

Once you zero in on a planned annual total, divide it by 12 and include the amount in your monthly budget. The rest requires follow-through on your part, with a promise to yourself that you'll re-evaluate your plan a year from now. "Following a systematic and disciplined approach to giving may remove the pressure … since you know who you are giving to and why you are giving," Kramer said. If you don't want to rely on your ability to set aside the amount each week or month, consider automating the process as much as possible. Much like contributing to a retirement plan, sometimes it's best to make the money disappear from your checking account without you needing to take action.

Remember, too, that if you itemize your deductions on your tax return, donations to charitable organizations will remain deductible under the recently passed tax bill set to take effect Jan. 1. Be aware, however, that beginning in 2018, the total value of all your available deductions would need to be greater than the new, higher standard deductions under the legislation — i.e., $24,000 for married couples filing jointly — or you won't benefit from the deduction for charitable giving. Because of that, experts say it's worth considering giving more in the remaining days of 2017 while the deduction could have more value to you.
