Some people will tell you that you do not need to keep receipts for deductible expenses. This is not correct. The IRS or Revenue Canada may ask to see your receipts any time that they want to ask.
When they ask it is your duty and responsibility to provide receipts. If you do not do so they may completely eliminate the business expense. You could end up with a big tax bill. Most likely, if this happens, you will be audited for the next 2 or 3 years.
This brings us to the question of how to collect and categorize your business or employee expenses. The system that seems to be simplest is to put all of January receipts in one envelope, all of February in another and so on. This is not a very good system.
A much better system is to look at last year’s tax form and make a list of the types of expenses that are listed. Prepare an envelope for each one. Place the receipts in the appropriate envelope. The reason for doing it this way is that whoever prepares your tax return will need to sort them into these categories. If they are already in the correct categories this is no longer necessary.
On some occasions I have spent a long time sorting office supplies from internet service etc. Once they are sorted I like to handle them in the easiest way, which is to take a batch of receipts for one thing and enter them all into an adding machine that produces a paper tape. As soon as I get to the end I wrap the tape around the receipts and put a few staples through the package. Then I write the name of the category on the tape and go on to the next batch. With a little practice this becomes very fast and easy to do.
I use the same system for adding up prescription receipts.
I am sending this to you now because I hope that you do not wait until the last minute to start preparing for your tax preparation.
A new feature this year is that the sales tax that you pay on large items may be deductible if you itemize deductions. The sales tax on an SUV may be a very large figure that would look really good on your Schedule A.
