8. Consider rolling over a 401k into an IRA. "Most people roll them over, as you have more investment choices outside of your 401k plan at work," says Minneapolis financial planner Sharon Bloodworth. If it makes sense, do it soon, as it can take up to 20 weeks to complete an IRA rollover. Also, Rives says, be sure to contact the bank or investment firm where you will be establishing the new IRA. You'll want to request the paperwork for a direct trustee-to-trustee rollover to ensure a nontaxable transfer.

9. Take a retirement test drive. One fail-safe way to be certain your overall financial plan will work in retirement is to try it out beforehand. If you plan to live on 75% of your current income, try it for a few months to see if it's reasonable.

10. Give notice to your employer, and talk about receiving pension payouts. Most businesses appreciate a few months' notice. Also, it can take several months to start receiving pension checks, so ask how soon you need to file the necessary paperwork. Go through your benefits statements carefully to check for errors. Make sure you get the benefits you were expecting to receive.

11. Social Security -- now or later? You should apply for Social Security three months before you plan to start collecting benefits. Consider how much you need the extra money, your life expectancy and other factors in deciding when to begin receiving benefits. For instance, a monthly benefit of $1,000 that begins at age 66 would drop to $750 if you started at 62. By contrast, waiting until age 70 would boost the monthly amount to $1,320.

12. Check your health insurance coverage. If you're under 65 and your employer offers retirement coverage, see what's involved. If not, look into buying your own health insurance, and calculate the expense as part of your overall budget.

13. Investigate Medicare. Most people do not understand how Medicare works or what their Medicare supplement and drug plans do. Don't be one of them. You need to sign up for Medicare three months before your 65th birthday (sign-up is easy online).

"Otherwise, you end up paying a penalty for the rest of your life for your Medicare Part B (medical insurance) and Part D (prescription drug) premiums," says Dover, N.H., financial planner Faye Doria. An easy-to-follow introduction to Medicare is here. If you're still working at age 65, talk to your company's human-resources department about how to coordinate employer and Medicare coverage.

14. Check other forms of insurance. Go over every type of insurance you currently have, including life, homeowners and auto insurance policies. For instance, you may find you have more life insurance coverage than you need. Other forms of coverage, such as disability insurance, may simply be unnecessary in retirement.

15. Look into long-term-care insurance. If you don't already have it, investigate long-term-care insurance before you actually retire. It's expensive, but it pays for expenses such as stay-at-home help and nursing home care. Consumer organizations generally recommend a maximum coverage of four years. The federal government has further information here.

16. Check your beneficiaries. This includes traditional IRAs, Roth IRAs, 401k's and any other retirement accounts. As Doria notes, the money from such accounts goes to the beneficiaries you name in the plans, rather than to the benficiaries noted in your will. You'll also want to check beneficiaries on life insurance, joint accounts and payable-on-death or transfer-on-death accounts.

17. Check your debt level. In a perfect world, we'd all retire debt-free. But that's often not the case. If you have credit card debt, car payments and the like, pay them down as much as possible before you retire. Another option is to refinance your home and roll your debt into the loan amount. You may end up paying less overall (and mortgage interest is tax-deductible).

18. Consider downsizing. You may be living in a house that's bigger than you need or can reasonably afford. If so, you may wish to downsize. Not only might you save on your mortgage and property taxes, but a smaller home may require less upkeep, freeing you to enjoy other aspects of your retirement.

19. Do you want to continue working? Retiring doesn't necessarily mean stopping work. Many retirees work at jobs they genuinely enjoy, such as in a flower shop or a vet's office. Others turn their hobbies into businesses. Not only can post-retirement work be fun; it can also help pay some bills, leaving your savings all the more intact. But, depending on your age and how much you earn, your Social Security benefits may be affected. Check here for additional information.

20. Make sure you retire to something. Too many people retire simply to get away from work, only to find themselves bored and restless. As you approach retirement, identify what you're retiring to, be it a second career, travel, more time with your family or some other rewarding goal. That makes all your planning all the more fulfilling.

Just don't retire to watch more reality TV. Remember, you gave that up.
