I use a Canon 6D with a Canon 430EX II and want to fire the flash off-camera with high-speed sync. Can the 430EX II work wirelessly with only a Yongnuo YN-622C-TX on the camera, or do I need an additional receiver on the flash? I’m looking for the lowest-cost way to get wireless HSS.

No. The Yongnuo YN622C-TX is a radio transmitter. The built in receiver in the 430EX II is an optical receiver. The two are not compatible without a radio receiver YN622C on the 430EX II. The YN622C runs about $35-40.
Your other budget option is to use a 90EX as a master flash to control the 430EX II. They go for around $45 on eBay. But the small size and guide number of the 90EX means the range will be somewhat limited, especially outside in bright light. The 90EX is marketed as a compact flash for the EOS M series of cameras, but it will control any slave flash compatible with the Canon E-TTL wireless optical system. This includes HSS functionality.

No. The YN-622C-TX is a radio transmitter, but the Canon 430EX II only has Canon’s optical wireless slave mode built in. It cannot receive Yongnuo 622 radio signals by itself.
To use the 430EX II off-camera with the YN-622C-TX and keep HSS, you need a Yongnuo YN-622C transceiver attached to the flash as the receiver.
Lower-cost alternatives mentioned by the community are optical wireless options, such as using a Canon-compatible optical master like the 90EX to control the 430EX II. That can support HSS, but optical systems are less reliable outdoors and require line of sight.
If you want built-in radio reception, you’d need a different flash/system entirely, such as a Canon RT-compatible flash with an RT transmitter, or a Yongnuo flash with a built-in 622 receiver.
