After you file

It depends. Yes, if you are a US citizen or resident alien (No if you are a nonresident alien). According to the IRS, a US citizen or resident alien is required to report all worldwide income (in USD) on your federal income tax return

If you already recognized the gain on this sale on a prior year's income tax return, just transferring the money to the USA will not require any reporting on your US income tax return (except for possibly Form 8938). You may also need to file an FBAR (see below).

However, if you did not recognize the gain on the sale of this foreign home already, you would only have to recognize any capital gain on the sale for US income tax purposes so only that portion of the money received that represents the gain (net sales proceeds less cost basis) would be taxable on your US income tax return (the IRS does not allow the recognition of a loss on the sale of a second home that was a personal use property).

Additionally, you would be able to take a foreign tax credit (passive) for any foreign taxes that you paid related to the gain on the sale of the foreign property. see this link Claim Foreign Tax Credit

The Internal Revenue Service has no official exchange rate. In general, use the exchange rate prevailing (i.e., the spot rate) when you receive the property, made any capital improvements and sold the property. Please refer to the following IRS links for more information about Foreign Currency and Currency Exchange Rates and Yearly Average Currency Exchange Rates
