Frequently Asked Questions

Is how to write a reasonable cause penalty letter something I can handle myself?

Sometimes. Simple balance or notice issues may be manageable if records are clear and no deadline is imminent. Larger balances, levies, liens, payroll taxes, missing returns, or disputed facts usually justify professional review.

Will this stop penalties and interest immediately?

Not automatically. Many resolution options help manage collection pressure, but penalties and interest may continue unless the IRS or state agency grants specific relief or the balance is paid.

What should I do first?

Identify the agency, tax years, balance, notice deadline, filing status, and whether any levy, lien, appeal, or audit deadline is active before choosing a response.
