Independent provider

So situation is I always try to have enough taken out of each job to get something back at the end of the year  .... This year i have become an ip (independent provider) caregiver with a live in and have learned they dont tax live in care providers. So im wondering if that will have a major impact on what i get at the end of the year as they told me my income shouldnt count against me but i dont want to get to the end of the year and owe and or have nothing back how can i make sure im not losing out? And make sure im getting our money back and i wanted to make sure that i wasnt misinformed about not having to be taxed as a live in care provider.  Thanks
