Question: I am creating a column in SharePoint list. This column is calculated. 

I am using below formula as of now: `=""&"INC0000"AutoID`

This shows results like: `INC00001`, `INC00002`, etc.

I want to change and show results like: `20151`, `20152`, etc.

Where `2015` is current year and `1`,`2` is ID. 

If user enter data next year then output should be like `20161`, `20162`, and so on. Year should be current. 

Please anyone can share formula for this. Thanks

Answer: 
I know it is old topic BUT ... the above suggestion `=YEAR(Created)` returns `10/09/1905` instead of the current year `2018`.

Instead I have used the following syntax: `=TEXT([Created],"yyyy")` which works fine on existing entries but if a new entry is done, it shows `1899` instead of year `2018`.

For some reasons the [ ] seem to disappear once it is reloaded.
Bucki, make sure the data type of calculated column is set to "Number". I found that when the data type was set to Single Line of Text, the 1899 was being returned. Setting it as "Number" produced the expected result.
