Hello,

I've already submitted my individual tax return for 2014 with a Form 4562(I put the date service 1/1/2014 to calculate my depreciation)..

However, the thing is that I was supposed to claim this depreciation for my 2011,2012 and 2013... actually my rental service started 1/1/2011.

I am considering to file a 1040X form. Here are my questions.

1. Do I need to submit Form 4562 again for 2011 ~ 2013 each?
I don't think so.. as far as I know, I only need to submit one 4562 form..
Since I already submitted the form 4562 for 2014, then I don't need to file the form 4562 again when filing 1040x form for 2011~2013?

2. Then how am I supposed to calculate my depreciation for 2011~2013?
Should I use the date service from 1/2011 to re-calculate my depreciation for 2011~2013?

Thanks,
