Do I need to show 400,000 baht in my bank account every year for my marriage visa extension in Thailand?

The user inquires whether it's necessary to maintain 400,000 baht in their Thai bank account for their subsequent marriage visa extension after the first extension has been granted using that amount. They also ask if showing a monthly income over 40,000 baht with bank statements could suffice for the next year. Comments suggest checking with the local immigration office, as policies may vary regarding income types accepted for visa extension.
