Capital Gains on real Property:
Although you should use a certified accountant or lawyer you can calculate your capital gains using a free program by Brazilian IRS (Receita Federal). It is "GCAP2008", "Ganhos de Capital 2008".

Single properties owned for 5 years are exempt to R$440,000. Worst case scenario is that you own more than one property and are cashing out. The capital gains rate is 15% but the bottom line is more like 5-6% of the gross gains. As an example, a property purchased in 1986 for R$5000 selling for R$900,000 in 2008, your capital gains using above program will be R$49560.
