If you have not done so already, you should visit the My Social Security website. Before you can take advantage of this service, you need to set up an account with a password. Social Security makes this process rather more complicated than it needs to be. But, once you have set up an account, you can go online to check what information Social Security has for you. In particular, you can check your earnings record. This will show what Social Security has listed for your reported income, all the way back to when you first started working. It is important to check this for accuracy. In my own case, Social Security has twice listed my earnings as zero for an entire year. Unless corrected, an error like this can affect your retirement or disability earnings. Compounded over time, this could amount to thousands of dollars. At My SocialSecurity, you can also get an estimate of what your retirement or disability benefits will be. This can be very helpful for financial planning.
