The rise is due to so-called winding-up expenses claimed by MSPs who either stood down or were not returned to the Scottish Parliament at the 2011 elections, Holyrood said.
Excluding these costs, the total expenses paid out to MSPs was just over £11.3 million, representing a decrease of just more than £500,000 on the previous year.
A total of 48 MSPs claimed winding-up expenses in 2011, which include staff salary costs, staff redundancy and office and accommodation costs.
A spokesman for the Parliament said: "Once election-related winding-up costs are set aside, we see a fall of more than £0.5 million in members' expenses, which reflects the two-year pay and expenses freeze that Holyrood has in place.
"The Parliament is on course to achieve a 12% saving over four years by 2014/15, which means its annual expenditure will be down by £9.5 million in real terms."
