Last minute tax preparation not only costs a few night’s sleep, it can also cost you money. Remember you don’t pay taxes on what you make; you pay taxes on what you make minus your expenses and deductions, so don’t wait until tax season to organize your information. First step, buy a good accordion file. Then keep records of your taxable investments to help you calculate gains and losses. Keep your business receipts organized and separate from personal expenses (we suggest a business bank account and/or credit card). If you’ve made home improvements that qualify for tax credits, keep your receipts in a separate file. Staying organized takes just a few minutes a week, but it can save you a lot of headaches when it comes time to file your taxes and will reduce the risk that you’ll miss a tax deduction.
