Here is something else that you may find helpful. I have just found out that Canadian Income Tax and T4 slips are based on Cash accounting - meaning you don't count revenue until you actually receive it. That explains why my accounting reports never quite balance!
For example, if you did a job in December 2002, but got your cheque in January 2003 - the income is counted in 2003. I didn't know that until now!
Most small business accounting software uses accrual accounting by default, which counts revenue when you earn it NOT when you are paid. This is why your accounting may not always jive with your T4's.

While I'm on the subject of accounting and taxes, here's a warning:
Quicktax may be the most popular tax software in Canada, but there is a MAJOR problem with it.
You know how they make you call in to register Quicktax when you first install it? Well, if you try to open Quicktax files from past years, you have to RE-REGISTER if you have made any changes to your computer such as a hard drive upgrade or new version of Windows.
I recently tried to open Quicktax 99, which I paid for and registered years ago. It completely prevents me from opening it until I re-register with Intuit! They say I need a page from the manual I threw away 4 years ago to do it! "Oh, you don't have that manual? I'm sorry, you will have to RE-PURCHASE the software."
That's right, I paid and registered 4 years ago, but because of Quicktax's extremely restrictive "copy protection" I have to
buy it again if I want to see my 1999 tax return!!! I was also told that their registration database from that far back has been deleted - so they can't help me.
What if someone needs access to tax calculations years later? What if they are audited and CCRA want's to see forms from previous years?!? What if Intuit/Quicktax goes out of business and can't provide the magic registration codes needed? You're screwed, that's what!
I will make it my personal campaign to discourage as many people as I can from using Quicktax / Intuit products. This includes Quicken and the Quickbooks accounting software. All of their programs have these extremely restrictive copy-protections built in, and there is a very serious risk that when you need to access historical accounting and tax data
you will be locked out of it!!.
I am all for publishers protecting their rights, but software that essentially self-destructs after it is used is taking it just a little too far. Accounting and tax data are crucial to any business. Software that holds this data for ransom should be outlawed![/size]
An excellent alternative for small business accounting is Simply Accounting 2003 (
http://www.simplyaccounting.com/ce/default.asp ). Same or better features than Quickbooks, less restrictive "rights management", cheaper, interacts better with other programs like Microsoft Office.
For better, less-restrictive tax software check out Cantax (

Avoid QUICKTAX, Quickbooks and Quicken at all costs, or you will be sorry in the future!
