I filed an extension (on 4/15/2019) to file my 2018 tax returns. Then missed the 10/15/2018 deadline.
I am almost done with my taxes. I will not owe any money because I am running a loss from my rental property business.
What penalties or fines is the IRS going to hit me with?
Filing late when you do not owe is not a problem ... only folks who owe are penalized. However the efile system is closed for 2018 returns so you must print, ink sign & mail in the return now. The ONLINE system will go offline tomorrow night so if you have already started the return you have until then to finish & print the return.
How can I file my late 2018 taxes?
To complete and file a 2018 tax return using TurboTax you would need to purchase, download and install on a personal computer one of the 2018 desktop editions from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/
A 2018 tax return can only be printed and mailed, it cannot be e-filed.
