Most Americans are required to file an annual income tax return. Those that are lawfully excluded from filing are individuals who make below an established amount of income. However, for everyone else, failing to file is a crime that can be prosecuted by the I.R.S. and may result in penalties such as fines and jail sentences. If you are unable to pay your taxes at the time they are due, you may ask for an extension. This extra time will cost a little more than your original taxes, but it can help you avoid the criminal penalties of failing to file. If you are hesitant to file because you have failed to do so in the past, it is a good idea to contact the I.R.S. to work out a payment plan. You will be required to pay all back-taxes, but by personally bringing this issue to the I.R.S.'s attention, you may avoid the criminal penalties. For information on taxes and filing, talk with a professional tax preparer or tax attorney.

翻译:绝大部分美国人被要求申报每年的个人所得税,个人收入低于（最低社会收入）可不申报个人所得税是合法的,然而,对其他人来说,如果没有申报个人所得税就是一种犯罪,将会被税务局起诉,结果可能是被惩罚比如罚现金和被判监禁。如果你不能按时交税,你可以要求延期。这段额外的宽限期将会使你多支付一点费用,但它可以帮助你避免因未及时申报而受到刑事处罚。如果因为过去你没有及时申报而让你现在犹豫不决是否申报,与税务局联系列出一个偿还计划表算是一个不错的主意。（这样做后）会被要求偿还所有后面未缴的税,（从未缴税之日起算至现在）但是这种个人主动交待问题的做法,你可能避免了刑事处罚。想了解有关税收申报方面的信息,可与税务专家或者是税务律师联系。
