The following has nothing to do with Deferred tax assets.

"2017年，川普总统签署了“减税与就业”法案（Tax Cuts and Jobs Act，TCJA）。为了鼓励企业在本土进行投资和研发，法案给出多项税务优惠，比如允许企业将符合条件的投资和研发支出100%全额在当年抵扣收入。而在此之前，这类支出要分摊到若干年度去抵减收入。"

Meta did not use the above tax deduction. Its accounting expensed them earlier than tax did, hence creating lots of deferred tax assets. I think that is why 小楚disagrees with you. I have explained to her down below. 

所有跟帖： 

• 你说的比较接近了，只是具体实务没有tax coupon这东西。 -楚怀沙- ♀ (94 bytes) () 01/22/2026 postreply 21:46:22

• 你说的我都知道。我是说给这里不懂会计的人听的。我已经说的很清楚了，给投资人听，不是给专业人员。怕他们听不懂。 -aloevera- ♀ (58 bytes) () 01/22/2026 postreply 21:55:41
