Is a joint sponsor required if my income is at 125% of the poverty guidelines?

I am applying for adjustment of status through marriage. I am currently allowed to work and stay in the US through DACA. I make enough to be considered 125% above the poverty guidelines. I know the I-864 form has to be filled out by my spouse, but there is a section where the sponsor, whether it be my spouse or a joint sponsor, can take my income into account to meet the guidelines. So I'm wondering if I really need a joint sponsor or if my spouse can file as my sole sponsor and then just take my current income into account?

As long as the petitioner makes 125% of the poverty guidelines then a co-sponsor is not required.

125% of the FPL is a minimum requirement. Below that and you must have a joint sponsor. Above that and you may or may not need one. The IO makes a decision on the public charge concern based on the totality of the circumstances.
