The end of the year is quickly approaching and for those of us who have a business and make business expenses, it's a good time to make some calculations and see how much you're going to pay Uncle Sam this year. The advantage of doing this now is that if your tax liability is too high, it's a perfect time to make some extra business expenses before the year is through.

Here's a few things you can do to increase your business expenses yet not spend foolishlly.

• If you've been wanting to upgrade your computer, there's no better time than now.
• Pre-pay your advertising expenses for the next few weeks/months in advance.
• If there's this business investment you've been hesitant to make, this could be the extra motivation you need to take the risk.
