YEAR(TODAY()) + 1 returns next year.
YEAR(TODAY() + 365) returns next year (unless today is January 1 of a leap year).

Syntax
YEAR(when)
when- ADate,DateTime, orTimevalue.
Note
Some constant values, such as "MM/DD/YYYY", are evaluated as a Date value by AppSheet. Similarly, "000:00:00" is evaluated as a Duration value. This doesn't mean your spreadsheet data must use the same formats: the date and time formats in your spreadsheets are determined by the locale/language setting. Column will always be evaluated as the type of column. Additionally, you can convert data, both columns and string literals, to specific types using functions such as DATE(), TIME(), or DATETIME().
