税单用英语怎样表达?用英语说“三个月的税单”具体请您说一下税单用英语怎莫说?

今年的税单必须等到明年才能拿到,这句话用英文怎么讲?
The taxation bill of this year is not available until the next year
The tax bill of this year can't be obtained until the next yea

税单应该翻译为 tax invoices.并非税表单之类的.其余参考楼上：
You may/can use your tax invoices to apply for financial assistance
