I'm not understanding what there is to "Play with". Foreign taxes are deducted in the Foreign Taxes Paid section under the Deductions and Credits tab. Now if you're talking about property taxes on foreign rental property, those are claimed on the SCH E in the "taxes paid" box of the rental expenses section. I think that box is labeled "Real Estate Taxes" in the program. Or are you talking about sales taxes or some other tax imposed by a foreign taxing authority when you sell rental property?
Regardless, you claim it in the tax year it's paid. We don't get to pick and choose here.
