how tax bracket calculated for considering family income.

I have employed income for $55000 which tax already deducted by employer. tax bracket for my income is %17. my wife is self employed income with income of 150000 with tax bracket for example %25. our household income will be around $200000. Is this mean when tax calculated at the end of the year we will pay more taxes based on 200k tax bracket. please clarify this for me.

regards,
