No, husband and wife individual industrial and commercial households, the tax will not check the bank card flow of both parties, because you are an individual merchant, not a large and medium-sized business, enterprise or general VAT taxpayer, you have to pay a fixed tax, and the tax will generally not check you. But if you don't record your income and cost, and the amount is quite large, you may be investigated. If found, it will make you pay taxes and late fees. So don't evade taxes and be a law-abiding taxpayer.
