This has been tested in five random towns, each town was looked at completely. Daily upkeep, amount of residents, amount of residents with no tax (Town ranked members VIP, Assistant, Builder, Recruiter, Co Mayor, Mayor) and all five towns it was correct for three days. I have also heard from 2 other towns who were checking for days and it also was correct. If you notice a tax issue again please let me know but I would look into the towns #'s again and see if you may be missing something, residents exempt from tax, nation tax, embassy owners with no $$
