Penalties are not always final. Depending on your situation, some or all of them may be reducible through penalty abatement or by contesting the IRS’s position — it’s worth talking to Wiggam Law about whether relief applies to your case. Interest is harder to remove, though it can sometimes come down when the underlying penalty does. No outcome is guaranteed.
