The question is, why do you want the record type id? Is it so that you can limit your query?
In that case

    Select Id
    From account
    where RecordType.developername = 'Business'
and you have saved a query :)

You can also use it on related objects

    Select Id
    From case
    where account.RecordType.developername = 'Business'

And if you really need the ID for some reason, maybe you can get it while you are getting your data?

    Select Id, RecordTypeID
    From account
