Some states offer no base payment to state senators while other offer no per diem payment.

Basic Salaries by Term
Some states pay their senators by term, instead of annually.

Virginia paid legislators $18,000 for each year served in the Senate and $17,640 for each year in the House of Delegates, according to the NCSL.

Per Diem Salaries
Most state legislatures pay senators on a per diem basis, which covers any expenses incurred for tasks completed on special projects away from home. Many legislatures prefer this method as a main method of payment, as it allows senators to be paid only when the state legislature actually meets. Alabama, for example, pays senators $3,958 a month plus $50 a day for three days during each week the legislature meets. Michigan allows for a $12,000 annual expense allowance, and California paid $173 for each day its Legislature is in session in 2010, according to the NCSL.
