Penalty relief due to reasonable cause: If you were affected by the pandemic or other circumstances, the IRS may be able to remove or reduce some penalties due to reasonable cause, but only if you tried to comply with the tax law but were unable to do so due to facts and circumstances beyond your control. If this applies to you and you have the necessary documentation to support your claim, you can call the toll-free number on your notice to speak to the IRS or you can seek professional assistance from competent tax experts.
