Can I file an extension for this year still acquiring info on a 1099

Yes. But you are technically still considered late for filing the extension after April 15th. 

Click here to file an extension.  Remember an extension is just for extra time to file, not extra time to pay.  If you are going to owe anything, you will still need to pay by April 15th. 

You can pay directly via the IRS website which is the recommended way or you can pay by check.  Be sure to include your SSN on your check and the tax year. 

if you live in Maine or Massachusetts you have until 4/17 to file an extension or return. Any other extension done after 4/15 is invalid (unless filed on or before 4/15 and rejected then you have 5 business days to refile). if you are due a refund it does not matter. if you owe and didn't pay you now have a potential 5% penalty and interest for late filing and payment. the penalty increase and interest increase the later you file and pay
