事实经过：
小弟是从某科技公司离职的员工，当初拿的是预聘约，含预聘奖金
但是未待满一年即离职，依据合约交回预聘奖金，但刚刚要报税时发现这笔缴回的钱
该公司将其依然算入我的所得并需扣税
以下是关于预聘奖金缴回的部分合约原文
In the event that you resign from OOOO, on your own accord during the first
year of service, the full quantum of the sign-on bonus you received shall
be returned to OOOO before your last day of employment, regardless of any
taxes (income tax, supplementary insurance premium, etc.) that have been
deducted for such bonus.
问题：
请问这笔税金我该缴吗@@，还是应该去诉愿呢?
我是有查到一位缴回50万预聘奖金向财政部诉愿成功的决定书啦...
(财政部诉愿决定书第10202172号)
先感谢各位帮 小弟/小妹 解惑或提出建议，如内容尚有不足，盼请提出需补充之处。
