MPs were reimbursed for more than 500,000 euros spent in the first six months of 2014, a daily reported.
Sixteen deputies made maximum use of their allotted reimbursements, said Postimees.
By law, MPs can have an amount equivalent to 30 percent of the salary of an ordinary member reimbursed, so each member could get up to 6,245 euros reimbursed, the paper said.
The latest report released by the Government Office shows that the ones who made maximum use of the amount were Reform Party members Deniss Boroditš, Tõnu Juul, Tarmo Leinatamm, Kalev Lillo, Kristen Michal and Kalle Palling, Social Democrats Kalvi Kõva and Marianne Mikko, IRL's Marko Mihkelson and Liisa Pakosta and Center Party members Lauri Laasi, Mihhail Stalnuhhin, Olga Sõtnik and Peeter Võsa, as well as Ester Tuiksoo, who is no longer in the party, as she was convicted of a crime.
Social Democrat Jaak Allik was 87 cents short of the ceiling.
The greatest economizers were Reform's Paul-Eerik Rummo and Tiina Lokk-Tramberg, who used 1,775 and 1,778 euros, respectively.
