Not exciting—but important to know: Each year IRS adjusts charitable gift premium rules, tax tables, personal exemptions, standard deductions and other tax provisions. Here are the key charitable figures for 2018 from Rev. Proc. 2017-58, 2017-45 IRB 489 (Nov. 6, 2017) and Rev. Proc. 2018-18, 2018-10 IRB 392 (March 5, 2018).
