If the declaration of independence was never signed, we would still be under control of England, we would have no president or leader other than England's Monarchy. Everything we work for would be done for the English government, our taxes would go to them, and our military would be England's military.
Had the Declaration of Independence never been drafted i believe that the United States of America would still be under Britains thumb. This being said one can assume that the tax policies would be severely different as they would change with each monarch, but yes taxation without representation and over taxation would still be a problem.
I hope that answered the question the specific 'Problems' weren't outlined so i i assumed you were referring to the problem of Taxation
