First off, the internet writing definitely stays--from a tax perspective, internet writing is definitely worth the effort! I've even upgraded my internet connection and I'm going to be investing in a new computer: a Mac Mini (I have not had an Apple product since the days of the Apple ][e).
Because the internet writing is starting to pay so well, I'm going to be investing more time in the process, and probably moving articles around for a while, or rewriting them and posting to other sites.
Also this year, I'm reviewing my record-keeping practices, and investing in some low-tech devices to keep my tax records organized. While I may make a little less money this year (after all, I won a ton of writing contests last year), I'm expecting that on my 2012 taxes, I will see a huge jump!
By the way, you should have to write out a check at the end of the year to the IRS. If you are getting a tax refund, you need to rethink your investment strategy.
