Iceland has a concentrated tourist season, peaking from mid-June through August. Many Icelanders think the summer tourists don't know what they're missing. Iceland offers plenty to do in spring, fall, even winter, and prices are dramatically lower for airfares, car rentals, and accommodations.
If you paper file, it will take three to four weeks for the IRS to process the return and acknowledge your refund. If you e-file, you will get a notice of arrival within 24 hours and confirmation of refund within 72 hours.
The IRS strives to process all mailed returns within 21 days, with e-filed returns processed even quicker. However, errors or requests for additional information can slow down this process. Also, if you claim the Earned Income Tax Credit or the Additional Child Tax Credit, the IRS expects that refunds will not be received under February 27, 2018, assuming that the tax return has no issues. You can track the status of your refund with the IRS Where's My Refund tracking tool.
