Non-military service of twelve months is available for men whose conscience prevents them from serving in the military. Men who refuse to serve at all are sent to prison for six months or half the time of their remaining non-military service at the time of refusal. In theory, male citizens from the demilitarized Åland region are to serve in customs offices or lighthouses, but since this service has not been arranged, they are always exempted in practice. Jehovah's Witnesses' service is deferred for three years, if they present a written testimony, not older than two months, from the congregation of their status as baptized and active members of the congregation. Jehovah's Witnesses will be exempted from peacetime duty at the beginning of the age 29. Military service has been mandatory for men throughout the history of independent Finland since 1917. Soldiers and civilian servicemen receive a daily allowance of €5 (days 1 – 165), €8.35 (days 165 – 255), or €11.70 (onward from day 255).
