My wife and I are 50/50 partners in a corporation and I earn a separate income with a different company. Why did the bulk of our business income go under my name?

My wife and I are 50/50 partners in a corporation. I earn a separate income and she takes dividends from our business. When we filled out the financials. it placed a bulk of the business income under my name.  I did not take any money from our business and am in a higher tax bracket.  Why is the bulk of the income under my name?
