I recently wrote a two-article series about the importance of designating your tax payments to certain years and the mechanics of “how” to do it. Most people will just go with the flow and allow the IRS to apply their tax payments in whatever ways the IRS chooses to do so, no matter what is in your best interest. Take charge, and tell the IRS how to apply your tax payments. You will end up saving yourself money in the long run.
Here are the two previous articles I wrote about paying your tax payments:
Article 1: Can I Designate My Tax Payments
Article 2: How to Designate Your Voluntary Tax Payments
