Here's a thing:
A few weeks ago, I used TurboTax for my federal/state taxes. Have been using TurboTax the past 8 years.
When all was done, I had TurboTax "e-file" my returns. I didn't give it another thought for 24 hours. That's when I discovered e-mails telling me my returns had been 'rejected'. The cause given: Someone had already e-filed taxes under my name and SSN.
A few days later, I discovered a letter from the IRS that I had overlooked and put down. It informed me of this filing which IRS thought looked suspicious since it didn't resemble past years' e-filings. I called them, verified my identity by citing facts from my previous filing.
They advised me to print out my e-filed returns, sign them, attach payments, W-2s and 1009s to them and mail them in. They rejected the earlier fake submission, but I would not be able to e-file for the past year's taxes. This is, apparently, a huge problem in the IRS this year. It may have evolved from the Google breach of security last year in which tons of personal data was stolen electronically.
I immediately subscribed to LifeLock which, I'm happy to say, showed no further attempts to forge my identity. I've changed ALL my passwords, as well.
It's always SOMETHING, isn't it!
