The local tax electronic key you mentioned is the digital certificate (CA certificate for short) issued by Henan Digital Certification Center. On April 1 2005, the Electronic Signature Law of People's Republic of China (PRC) was officially implemented, which provided legal protection for identifying the identity of traders in electronic documents, ensuring the security of transactions, and signing or stamping by hand. Therefore, the electronic data transmitted by CA authentication has legal effect.

A 200 yuan is a CA certificate fee, just like a USB flash drive. Every year, 200 yuan pays the CA certificate maintenance fee of the local tax signing company, not the account fee. A CA certificate is like an electronic key. Without this electronic key, it is impossible to declare and pay taxes online every month. If your unit is small and the business volume is not large, go to the local tax declaration hall to declare and pay taxes online. At the beginning and end of the month, you can queue up and be mentally prepared.

I'm very satisfied with your serious answer, please adopt it!
