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.
You'll need to base the value of the year on the record's created date if you want it to reflect the current year. And, assuming your "AutoID" field works and increments as expected, your formula would be as follows:

```
=YEAR(Created)&AutoID

```
