Harbor Shield coverage includes full legal defense costs if your business is audited by the IRS or a state tax authority. This applies to credits and filings such as the Employee Retention Credit (ERC), Research & Development (R&D) credits, Minimum Essential Coverage (MEC) plans and the FICA Tip Credit. In addition to paying your attorney invoices, Harbor Shield also provides daily IRS transcript monitoring, which can detect early signs of inquiry months in advance. This proactive layer gives you peace of mind, knowing that if the IRS comes knocking, you’ll already have expert representation and guaranteed funding in place.
For ERC filings, Harbor Shield coverage is typically valued at $2,500 per quarter, providing up to $50,000 in legal defense protection per occurrence for the full IRS audit period (currently through 2030).
In most cases, this cost is already built into your tax firm’s service fees or included within your carrier’s coverage, so there’s no separate bill or unexpected expense for the business. This ensures simple, transparent protection with no hidden exclusions or surprise invoices. Discounts are available when multiple ERC quarters are covered, making it easy to scale protection affordably.
Your protection lasts for the entire statutory audit window, which means you stay covered long after your original filing. For the Employee Retention Credit, the window of eligibility extends through 2030, providing years of security with a single enrollment. Harbor Shield locks in your defense from day one, so even if the IRS sends a notice years later, your audit protection is already active. No scrambling, no gaps, no expiration before the audit window closes.
