SSA is never forced on anyone. If you never apply they will never bother you.
Perhaps you're referring to the increase offered through Delayed Retirement Credits. For each year you delay collecting benefits after reaching FRA (Full Retirement Age) you will get an extra 8% added to your benefits. You FRA is 67, assuming you're 63 now. You would get 100% at 67, 108% at 68, etc. You will get max benefits if you wait until age 70.
Many experts say if you don't need the benefits now, then wait until you do or age 70. Due to aging and health decline it is better to have higher benefits when you're older.
