I work on my taxes all year long. Most of the year i just try to get my receipts collected and organized so that I am ready in the spring to do the return. But, even just after I complete a return I look to see if I need to make any changes in my withholding, deductions I may have missed or want to take advantage of, or explore the effects that changes in my life (new house, child no longer a dependent, etc.) that may affect next years taxes. I also do this review in late summer or early fall and make adjustments in the current tax year as needed. All year long I try to pay attention to what the politicians are planning to do to change the tax law and how it will affect me.
