Since annatto powder is basically a form of carotene (found in abundance in foods like carrots), any yellowish-orange edible product can be substituted, but it depends on the flavour profile you're looking for.
Annatto is used to colour butter, margarine, cheese, and so forth. Its flavour is also quite mild, so you can often get away with substituting using turmeric or yellow food colouring with just a dash of orange mixed in. If money is no object, you could substitute saffron instead.
