In the KH in this area, they built on a detached little house for a special pioneer couple. They are not required to mow the lawn, do upkeep on the building or property because this becomes income and taxable. Besides the BOE has said that those duties are supposed to be training for brothers coming up the ranks as to their reliability (haha).
The US government has been working on the idea that housing provided to ministers, priests, etc., should be counted as income and taxed. I'm not sure what the status of that is.
Hopefully, these Bethelites have stayed in contact with some jws outside Bethel using perhaps their special status as Bethelites. Ray Franz and his wife Cynthia had no children but a jw that they had kept in contact over the years and visited often, helped them out with a job and housing. Although Ray had not paid into social security for the required 4 years (10 credits a year = 40 min required, working full-time), he worked for another 4+ years to qualify and his wife qualified for ss as his wife.
Plus, if your income is below a certain level, many people qualify for certain services, food, etc. I knew special pioneers under 50 who kept their income low on purpose so they would qualify for these and pay little tax.
