Here is one of the best deals in tracking business expenses, mileage and planning your monthly business budget for income tax purposes. The Greenblatt Business Expense and Mileage Log Book allows for up to 18 months of entries to help you document and track your self-employment business expenses. The book also has entries for logging quarterly estimated income tax payments for the Fed estimated taxes and up to 3 States estimated tax payments. No other book or log on the market has anything like it. The book is broken into 18 sections where you first can log your budget planning versus your actual expenses, your business mileage, your medical and charitable miles and has room for extra notes. You enter the months and years so stock up on several copies. If you have ever been audited by the IRS or respective state taxing authorities you already know that you need to have great documentation. This log can help you as well as remind you to track your receipts. The cost of this book may also qualify as a business expense for your self-employed business. Just keep this log book in your car, shoulder bag, knapsack, iPad case, or anywhere where you need to easily track your business expenses.Kim Isaac Greenblatt has been successfully helping people prepare taxes for over eight years and is also the author of several best sellers including "Bad Tax Idea, Good Tax Idea".
