My wife doesn't have any income....Can she by shares on her name with my money (that I give to her) so the profit she makes is taxed within her income range (will be below threshold) ? or that profit adds up to my income as it was my money to begin with ? If she indeed can, does she need a separate bank account ? can she by shares from a joint account (mine and hers)? what's the legal efficient way to go about this ?
