I completed my tax return and already mailed it. Now I’ve received a 1042-S from Harvard, which includes income I did not report. What should I do?

You will have to file an amended tax return in order to include the income listed on the 1042-S. Windstar (the online tax preparation software provided by the International Office) does not assist with amended returns, so you’ll have to obtain the amended form from the Internal Revenue Service (IRS) website.
