In addition to checking the data accuracy and closing the books, you should think about and plan for the up-coming year. Be sure your tax objective is aligned with your business goals.
Start by reviewing the numbers that show your actuals (from your P&L report), your forecast (based on where you think you can make adjustments), and the difference or variance for each line item. Now you have a working budget!
It might make it easier (and more palatable) to think of budgeting as profit planning. If you have a profit plan in place, then you can truly track your income and expenses in a fashion that gives you a clear plan as to how to increase your revenues and where to cut your overhead.
