Surplus for 21 months
For surplus income you stated anything over the allowed amount ie. 1755 (single) is surplus and you would pay the trustee
(50% of $1,000) and (75% over $1,000)…if it was stated at the beginning of the bankruptcy by the trustee that I would have to pay for 21 months would I just have to pay 50% of whatever surplus I make or will I still have to pay 75% for any surplus (raise or bonus) to the trustee for the 21 months? just wondering if the percent would change because I am in in for a longer period of time

The percentage rules still apply regardless of the time estimates provided by your trustee. For more detail contact your trustee for an explanation as to the reasoning behind this.
