Delaware LLC Late Tax Filing

I own a single-member Delaware LLC that actively provided services to U.S.-based clients. Unfortunately, the federal and state filings for the last two tax years were never submitted, so I now need a U.S. tax professional who can: • Prepare and e-file all required federal and Delaware returns for a single-owner LLC with U.S. business income, covering the two missing years. • Calculate any interest and late-filing penalties that apply and confirm the exact amounts due. • Draft and submit a well-reasoned IRS penalty-abatement (reasonable-cause) request so I have the best chance of reducing or eliminating those penalties. • Handle the accompanying Delaware annual report/franchise tax forms and bring the state account back into good standing. • Provide clear guidance on keeping the LLC compliant going forward. I will supply bank statements, invoices, prior-year bookkeeping data, and any supporting explanations you need. Please let me know your relevant credentials, experience with late filings for Delaware LLCs, and an estimated turnaround time for completing everything above.
