The Scottish champions took the decision to allow their fans to benefit financially after what they described as a 'positive year on and off the field for the club'.
Neil Lennon's side reached the last 16 of the UEFA Champions League, including a home victory over Barcelona, retained their SPL title and have a Scottish Cup final date to look forward to next month.
Chief executive Peter Lawwell said: "Celtic has enjoyed a wonderful title-winning 125th birthday season and I congratulate Neil and the players for all they have done.
"We have now won back to back SPL titles, secured a Scottish Cup final place and have put Scottish football back on the map at the highest level, as one of the top 16 clubs in European football.
"Such a run of success has led to a very positive year off the field for the club and we wanted to make sure that our fans share in this success.
"The backing of our fans has, as ever, been crucial. Domestically and in Europe they have once again been right with us and we felt it important that we rewarded their commitment by making this gesture.
"Our foundations are strong, we have real stability and we look ahead to a bright future for the club with absolute confidence."
Celtic have also introduced a number of measures to attract younger fans to Parkhead, including an improved family stand area and a new facility and viewing area for disabled supporters.
Along with the cheaper adult season books, Celtic have pitched tickets for under-18s in three brackets - U13s = £50 (£2.38 per match), 13-16 years £105 (£5 per match) and 17-18 years £186 (£8.86 per match).
