What to do about those unfiled taxes 

Correct. The IRS can't even process older returns without tax payers consent.

They send a notice. If you haven't got your IRS mail in a while, you always can request you account transcripts, they will tell you. Or try our paid service if you'd rather not deal with/attempt to understand the IRS yourself. www.irsmedic.com/kb/services/tax-disputes-and-workouts/ttd/total-tax-diagnosis.html

The IRS "claims" they send out notices to give you your right to respond, but often those notices are sent to the last known address on file. If a taxpayer doesn't file a change of address form when they move (avail at www.irs.gov), the taxpayer who has moved without doing that never finds out about the action until the SRF (which is when the IRS prepares your taxes for you, sends notices requesting you sign it, no response for that year, what they complete is your tax return for that year, plus usually for average tax payer is about 6K. ...just like what's said in this video; and now, these delinquent missing tax years for tax payers are farmed out all over the United States to examiners located at numerous IRS locations all over the USA and Puerto Rico to file your return for you. Not to over ride, because this such a great channel with accurate info, I almost shouldn't comment; but, if you, as a US citizen or taxpayer, call the IRS (and navigate thru the 20 minutes of automated phone system waiting to talk to a customer service rep) you can ask them "Do I have any actions pending on my file with the IRS? ..and make sure to write down the Customer Service rep's name & their ID no. That IRS rep, if they can verify it's actually "You" on the phone, like ask you to provide your Name, SSN, maybe bank account info & date of birth or address they have for you on file, and you give them permission to discuss your tax information, they are legally required to tell you over the phone what years are currently being looked at for SRF, or actively being worked and may have to give you an Examiner's tel. no. for you to call them direct (more time on phone waiting), the examiner will tell you which IRS Tax office has your SRF for that year. A delinquent taxpayer could have SRF's at 3-4 different IRS offices. So, If it's NONE--you're LUCKY. Like said in this video stressed over and over--FILE YOUR TAXES. Even if it's late. Even if the SRF is CLOSED, you can request reconsideration (as stated in this video) & provide the actual examiners a copy of your filed & signed tax return. I'm not a paid advertisement for this channel. Consistently, if this were a baseball game, this guy running this channel is batting a 1000. Dead spot on accurate info. Time and time again.
