Sarah,
Most Dominican businesses, large and small, and home owners, rich and poor, know full well that they're supposed to pay for their water and electricity, and in the case of Santo Domingo, their trash collection. But many attempt to avoid doing so anyway. For example, I can't count the times I saw someone from CAASD was outside the door of the house of the owner of the DR's largest home-grown department store (take a guess which one!) trying to get someone to come to answer the door because the house hadn't paid its water bill in months!
By now, most businesses in SD, esp. the colmados, know that they are supposed to be paying taxes. During the Fernandez government, the Direcci?n General de Impuestos Internos (DGII) was cracking down on all deliquent taxpayers, esp. businesses. Colmados were being closed, and even one supermarket chain went out of business because of their back-tax bill. The retailers association has been grumbling about this since 1998 or so.
If you want more info on DR tax policy and DGII procedures, visit their website at www.dgii.gov.do
Hope this helps.
Regards,
Keith
