Seriously, take a GOOD look at your overall picture compared to last year, the last five years.... If yours is like mine, the LAST THING you want to do is DIY - GET A TAX ACCOUNTANT PRONTO! If you don't know a good one, talk to friends with their own businesses, see who they use. Interview several before you choose - it is often VERY IMPORTANT that you feel you can have a "friendly working relationship" with professionals like this. If you are iffy about something or a bit put off by an attitude - DON'T HIRE HIMMER! Gut reactions should generally be listened to....
And, from personal experience, don't hire the guy whose office complex exists cheek-by-jowl with attorneys. It's too easy to get handed off when you need legal representation to someone who is totally unsuitable, simply by "contamination".... and yes, that's a totally jaundiced attitude (LEGITIMATELY I might add *sigh*)....
[Edit: OH! DO NOT wait until the last minute to put things together or to request a filing extension! In other words, get your ducks in a row, and THEN postmark at the last minute, but be sure you HAVE those ducks in a row.... Here speaks a bookkeeper of many years' experience....]
