That really depends on the terms of your plan and how the courts in your district treat such things.  Thus, you really need to consult with a bankruptcy attorney in your area.  In most cases, the Chapter 13 trustee will require annual tax returns to be submitted and if it shows an increase in income, they can seek to have the plan payment increased up until you are paying 100% of your general unsecured claims. However, an argument can certainly be made that social security income should be excluded from that analysis since Congress excluded it from the means test, but most courts won't buy that line of reasoning.Mark J.
