I hate tax time as well. You're not alone!
Your accountant can also file an extension as well, makes the process easier but you have to pay any taxes due in April.
May I make a few suggestions for next year. After you get this year's stuff to the accountant this is what I would suggest. Get a large manilla envelope, one for every month. Then put everything in the envelope for that month. Try to take the time each month to organize the previous month's envelope. Sometimes just having one for each month seems to make the process easier.
Another suggestion is the following: The Neat Desk
Information about it can be found at: www. neatco .com
They have a payment plan that provides a good way to purchase. This scans the information, so you have it in paper format, electronic format and then into a spreadsheet. This is also accepted by IRS for tax purposes.
You're not alone it putting off the task. I think it's a chore. I hate doing them, as last year I ended up paying. I didn't send my check in until the very last possible moment.
