Hel need advice thinking of giving up my 1 year biz because of high taxes made about 50k?

Hi everyone we own a pool service biz and made about less than 50k in profits and my new accountant without reviewing everything says that we might need to pay about 9K, I was shocked since i thought the first year we didn't have to pay much since we really didn't make much, we actually refinanced our home to start the biz and now the payments are so high that we are close to foreclosure,and now he gives us that bad news, i am so dissapointed and thinking if its worth having a small biz because this year has been so tough and if we did make aournd 50k we will have to pay so much back, is this how it usually goes?
