I have made several test returns using the 2018 program and the correct 2018 tax tables are being used even though the summary table shows a 25% tax bracket which is incorrect. However, just because the correct tax tables are being used doesn't mean that all entries will result in the correct tax being calculated since several parts of the program are not yet complete. You can use Taxcaster for making 2018 estimates: <a rel="nofollow" target="_blank" href="
