Most people are surprised to learn their taxes do not retire when they do. Up to 85% of your Social Security can be taxable, and required withdrawals from your retirement accounts start in your 70s whether you need the money or not. Here is a move you can make this month: pull last year's tax return and find your effective tax rate, then apply it to the income you are planning to live on. That is the number that actually hits your bank account. Most people plan around the bigger, pre-tax number and get surprised every April. The streams I lean on now behave differently at tax time, which is part of why I stopped counting on one number. Have you run your retirement income at your real, after-tax rate yet? -Rich This is one person's experience and research, not financial advice or a promise of results. Income from any stream varies.
