If your mother's name is XXXXX XXXXX on the account and her SSN is used then it should not affect your taxes. The assets and the income are still considered hers as she has not made a gift to you until you make a withdrawal from the account for your own use. However, there are some other issues for consideration. For example, if you file for bankruptcy or have a judgement against you as a result of a lawsuit then 50% of the account could be at risk even though the source of the funds in the account are your mother's. A durable power of attorney eliminates these other considerations as the assets are still considered hers and you are merely acting as her agent. However, make sure that the financial institution will accept the POA as drafted because in some situations institutions require their own forms to be used or require specific language in the document before they will accept it.
