The law doesn’t put a cap on generosity. However, when gifts to an individual exceed a certain amount, you’ll have to deal with federal gift taxes. In 2014, you can give up to $14,000 per individual (if you’re married and your spouse consents, you can double this amount). This dollar limit, called the annual gift tax exclusion, isn’t cumulative so if you didn’t use it in 2013, you don’t get any added limit in 2014. If the gift exceeds the exclusion, you can apply your lifetime exemption amount ($5.34 million in 2014), but this reduces the exemption your estate can take when you die.
Items, such as interest, state and local income and sales taxes, charitable contributions, and medical deductions, claimed on Schedule A of Form 1040. Itemized deductions are subtracted from adjusted gross income to arrive at taxable income. The amount of itemized deductions is also subject to a reduction when adjusted gross income exceeds certain limits.
