SQL Server add computed column in VIEW with conditions

Here is my situation:

In my table i two fields:

- Price (decimal (15,4)
- TaxId (int)

TaxId value is not stored anywhere but there are only two values (actualy 3).

- 1 (8.5%)
- 2 (20%)
- NULL (no tax)

Now i need calculated column in my view that would calculate new price with tax included.

Any idea?

I went with something like:

SELECT...
CASE TaxId
   WHEN 1 THEN Price *1.085 AS test
   WHEN 2 THEN Price *1.2 AS test
   WHEN NULL THEN Price  AS test END
FROM...

UPDATE:

I have managed to execute the query with success.

CASE dbo.Table.TaxId WHEN 1 THEN dbo.Table.Price*1.085 WHEN 2 THEN dbo.Table.Price*1.2 ELSE dbo.Table.Price END AS CalcualtedPrice

Now I only need to make CalculatedPrice as decimal (15,4). How can i set that?
