At Advington Stone, streamlined procedures are our core focus, not a secondary service. We specialize in the technical nuances of non-willful certifications and complex asset disclosures designed to proactively mitigate IRS penalty risks. Our immersion in these specific filings ensures we have the experience you need and can achieve compliance and peace of mind.
After confirming your eligibility, we onboard you via a secure portal with transparent, fixed-fee terms. We collect three years of data through structured questionnaires to prepare your amended returns and FBARs, followed by a dedicated strategy session to craft your non-willful certification. Once finalized, we provide a full digital package for review and manage all IRS submissions—including courier services—ensuring a smooth resolution without billing surprises. As you are likely aware, there are slight differences between SDOP and SFOP submissions and we are experts at both. The SDOP includes additional steps regarding a mandatory 5% penalty calculation and we are well versed in the nuances.
We aren’t just advisors, we are expats ourselves who understand the personal stakes of cross-border compliance. Because the majority of our practice is dedicated to streamlined filings, our expertise is honed by repetition. This specialization has resulted in a 100% acceptance rate to date for our clients’ submissions. By choosing us, you partner with specialists who are very familiar with the anxiety associated with these filings and have the expertise to ease your mind.
Contact us today to get started on your streamlined filing and move forward with peace of mind.
Our fees start at $2500/£2000/€2200*
