The time SNAP benefits last varies, but usually lasts anywhere from one to six months before benefits need to be renewed. When the person applies for benefits and receives an acceptance, the acceptance letter provides the start date and the date of renewal, if necessary.
SNAP benefits are intended as a temporary assistance to help low-income families provide food for the household. If the person's financial status has not improved when it is time to renew, he should submit a renewal application along with proof of the circumstances, such as recent paystubs and tax returns. The process should be repeated as often as necessary.
