taxes

Tomorrow I will do my taxes, and I'm hoping I don't owe much this year. I'm self employed so I have to send a check to the IRS every quarter (every three months) to pay for my contribution to Social Security, medicare, SSDI, etc. There's a chance that I've paid enough to merit a refund this year (which would be wonderful!!) but I'm not getting my hopes up because just as good of a chance that I will owe! :(
