Here are Six Possible Effects of a Government Shutdown
#1.) Your tax refund could be delayed, especially if you apply by mailing in a return and not using e-file. Also, the IRS would probably have to stop answering their hotline, so if you want to ask them tax questions next week you're out of luck.
#2.) A long delay for newly-eligible people applying to Medicare.
#3.) While the police are considered an ESSENTIAL service, some parts of the police process were cut down in 1995…including case processing, testing, recruitment, hiring, and even work on some non-violent crime cases.
#4.) The National Parks will close immediately, as will museums that rely on federal funding.
#5.) Long delays if you need a passport or visa application.
#6.) NASA will have to stop preparing any space missions.
