Can a defaulted SBA loan allow SBA to garnish Social Security income and if so what percentage?

Yes, a defaulted SBA loan can allow the SBA to garnish Social Security income. However, the amount that can be garnished is limited by federal law; typically, up to 15% of your monthly benefits may be withheld to repay the debt. It's important to note that certain exemptions and protections may apply, so consulting a legal expert for guidance on individual circumstances is advisable.
