You may need to check your entry- the tax should not increase more than the income. The joint ownership would not make a difference in this case.
The sole versus joint ownership might not make a difference for tax purposes, and there are different rules for spouses and other joint owners. When looking at ownership, joint account holders have the same rights to contribute or withdraw funds. There could be a tax issue if the co-owners are not spouses because if one owner claimed more income than their share of contributions. This is the assignment of income principle.
For example, an account was jointly owned by Marge and Greg (not related). Marge out $100,000 in, Greg 0. Greg received the entire dividend so he reports it on his return. This would be have to be treated as a gift because Greg would have no income on his own because he did not make any initial investment. Marge on the other hand, should report the income but does not so if it was not a gift she would be underreporting the income.
Gift come into play because there are unlimited gits allowed between spouses. Gifts are not reported as income to the recipient but in the example, Greg does not report the gift as income but the dividend received. The donor may have reporting requirements as well.
