This website started as a resource to provide explanations of the new tax laws passed in 2001. Commonly-used tax numbers for the current preparation year are posted, and the tax tips by definition offer general guidance, not complete details.
As a historical and maybe useful resource, prior sections for each year from 2002, (personal exemptions/standard deductions/tax numbers and any relevant tax law changes) are now accessible here.
For taxpayers in the Boston area seeking tax preparation services by a licensed enrolled agent offering expertise at reasonable prices, visit here.
