@Mike92ct - the tax on Line 18 of Form 1040 is the critical line item. Any non-refundable credit can reduce this line but to no lower than zero. So if Line 18 is $1510, then the limit of the Savers credit is $1510. if you have other non-redundable credits, the sum of all of them can be used to reduce Line 18, but again, to no lower than zero.
