I-864 Affidavit of Support - Can I Co-Sponsor myself?

[Serejun]

Hi Everyone.

I am new on Immihelp, as I started collecting all the documents for initial submission with USCIS, so decided to read on forums but I can't really find anything related to my case. Help would be much appreciated

So, for the last 2.5 years I was here on Deferred Action, I was granted an EAD card and was making over 30k anually. Paid/filed taxes on time.
Been working legally until August current year, and was not able to renew anymore.

My wife recently got a job, and makes over the Poverty Limit but she only started in September (see chart below)

Wife (gross annual income):
2016 - 27k employment started as of September 2016. Can she Sponsor with a letter from employer stating her income information?
2015 - 13k
2014 - 16k

Me (gross annual income):
2016 - 41k employment ended August 2016 (earning was around 30k until EAD expired)
2015 - 33k
2014 - 31k

With this mentioned, Can I act as a Co-Sponsor and file an I-864A Form if I can provide copies of my EAD and Tax Forms for recent years?

Many thanks!
