◉ Late Filing & Compliance
IRS notice & penalty-abatement response preparation
Received an IRS notice, penalty assessment or examination letter? We review it against your return, prepare the written response, penalty-abatement request or corrected filing, and give you everything you need to submit it. Responding to the IRS remains your responsibility as the taxpayer — our job is to make sure what you send is accurate, complete and properly supported.
Short answer
An IRS notice normally gives you 30 or 60 days to respond. We review the notice against your return and prepare the written response, a penalty-abatement request (Form 843, first-time abatement or reasonable cause) or a corrected filing for you to submit. We do not represent you before the IRS — you remain the person who responds.
Overview
Why this filing matters

Our approach
A catch-up that actually closes the exposure.
Coming back into compliance is less about the forms than about the story they tell together. The Streamlined procedures require the returns, the FBARs and a non-wilfulness certification that holds up — and the certification is where most self-prepared catch-ups go wrong, because it is signed under penalty of perjury on facts that need to be set out carefully.
We scope the whole picture first — every year, every account, every source — then prepare the package as one coherent submission, with the Form 14653 narrative written to match the returns behind it. The firm prepares and you submit; responding to the IRS directly remains your responsibility, quoted separately if it arises.
- Full multi-year scope taken before a single form is drafted
- Form 14653 non-wilfulness narrative written to match the returns it certifies
- Eligibility for Streamlined assessed honestly before you commit to it

02
Review
We analyse your position, flag any cross-border risks, and confirm the scope and fixed fee in writing before any work starts.
03
Prepare
Draft returns and schedules are prepared with plain-English commentary on key positions for your review.
04
File
You sign electronically; we e-file with the IRS / FinCEN and send you the acceptance confirmations for your records.
Pricing
Fixed fees — no surprises
Quoted per case, in writing, once we have seen the notice and the return it relates to. Corrected filings, amendments and late submissions are quoted as separate pieces of work — no hourly billing.
Prices are indicative starting points and exclude UK VAT, which applies to UK-resident clients only. We quote in writing once we have confirmed every source of income and your filing history for the years involved.
