never sleeps.

Next Tax Source is a private cross-border tax practice led by a licensed professional — an IRS Enrolled Agent who is also ACCA-qualified — and powered by fifteen specialist AI agents working continuously across three jurisdictions.

The Method

How a fifteen-mind firm conducts your affairs

i

Audience

A private consultation establishes your entities, jurisdictions and obligations. We map eighteen months of compliance before the engagement letter is signed — so nothing is discovered late.

ii

Connection

Your accounting platforms, banking feeds and documents are connected once. From then on, paperwork ceases to be your concern; our agents read, file and extract everything that arrives.

iii

Preparation

Fifteen specialists work your account continuously — books reconciled daily, payroll to the hour, every return prepared with full workpapers well before its deadline. A supervising intelligence reviews each deliverable against the firm's standard.

iv

Signature

A licensed professional — CPA/EA in the United States, ACCA-qualified accountant in the United Kingdom, licensed professional in the Emirates — examines, signs and submits. You receive a sealed summary, not a stack of forms.

The Team

Fifteen specialists. One standard.

Structured the way a great firm staffs an engagement — partners, specialists and a supervising mind — not one generalist stretched across everything.

Frequently Asked Questions

What does Next Tax Source do?
We are a private, online cross-border tax and accounting firm for the US, UK and UAE. Our core specialisms are US–UK expat and dual-citizen tax, IRS Streamlined Filing (offshore catch-up), and cross-border company tax — alongside bookkeeping, payroll and reporting.
Who reviews and signs my filings?
Every filing is reviewed and signed by our licensed professional — an IRS Enrolled Agent who is also ACCA-qualified — covering both the US and UK sides of your engagement. UAE filings are reviewed and signed by FTA-registered tax agents. You meet the signer, and can verify credentials, at your consultation.
I haven't filed US taxes for years while living abroad — can you help?
Yes — this is our specialty. The IRS Streamlined Foreign Offshore Procedure lets non-willful taxpayers catch up, usually with no penalties. Start with our complete guide or book a confidential review.
How much do your services cost?
Fixed-fee, scoped proposals — you approve the price before any work begins. See our pricing page, or request a tailored quote; most Streamlined and dual-filing engagements are quoted within one business day.
Do you work with clients remotely?
Yes — we are a fully online practice serving clients across the United States and United Kingdom (and the UAE), with a secure client portal, e-signatures and encrypted document exchange.
