There are still 2 unanswered questions then, at least in my mind.
1. Does the increase in property value on which I will be taxed accounts for the devaluation of the peso?
2. How do I get property evaluation done for taxes purposes... is it from DGII?
By the way, can I not sell the property on a smaller amount on paper (the 2 contracts method) so that there is not much difference between my purchase price and sell price?
I can't find it now, but the law on which this amnesty is based did say that the devaluation of the peso would be used in determining the amount on which any capital gains would be based.
DGII is the one that is calculating new assessment values on which yearly property/company taxes are bases and they calculate any capital gains taxes based on the difference between purchase and sale price.
From what I've been told, at least in the near term, the two contract method will still work, but some investors in more expensive properties are electing to pay the 3% transfer tax on the actual sales price and have that recorded rather than risk a potential 25% captital gains tax on a future sale.
