Since it is too much of a hassle doing the filing by ourselves, we leave it in the capable hands of the expert. I don't think it would do us any good if we even tried, because we would have to stay updated constantly on all the changes that take place each year.
It doesn't take much effort though finding some excellent crash courses online to obtain a tax preparer certification. A little determination, commitment, effort, and investment of time go a long ways and will benefit you for a long time to come.
I don't like juggling with numbers, but for those of you who do, an income tax course may not be a bad idea. You would be helping out many while expanding your own income at the same time.
Don't forget to file those next year!
