U.S. tax preparation

TFX, an expert in U.S. taxation, files tax returns for taxpayers in the U.S. and worldwide. All U.S. citizens and Green Card holders must file an annual tax return that reports their worldwide income, provided they meet the minimum filing requirements. TFX can file tax returns for Americans residing in 193+ countries across the globe. With years of experience in preparing expat returns, TFX can efficiently navigate complex state issues and address the specific nuances required by different professions. Additionally, TFX assists with specific expatriate requirements like FATCA and FBAR reporting.

Whether you are a repatriated citizen or have always lived within the U.S., TFX is here to assist you. Simply fill out our Tax Questionnaire and upload all required documents. Your return will be filed accurately and within the set deadline. TFX will optimize your return to ensure you take advantage of all credits and exclusions based on your unique personal situation.

Streamlined Filing Procedures - IRS amnesty program

The Streamlined Foreign Offshore Procedures is an IRS amnesty program, designed to assist American expatriates who have unintentionally failed to file their U.S. taxes for multiple years in catching up, without facing any penalties for late filing. The program allows taxpayers to file their most recent three years of Federal tax returns, along with their last six Foreign Bank Account Reports (FBARs) with no penalties. TFX has helped thousands of U.S. citizens get compliant, penalty-free.

Turnaround time:

Approximately 1 month.

For more information, please refer to Streamlined Program - Which years to file?


Tax projection

Major life changes, such as moving abroad, receiving a promotion, retiring, or selling property, often bring significant shifts in income and, with them, substantial changes to your U.S. tax obligations. The IRS requires that you make estimated tax payments in the same year your income increases, even though your actual return won’t be filed until the following year. This is where our Tax projection service — a future-year tax calculation — can help you stay ahead.

The main goal of this service is to help you prepare for your upcoming tax obligations by explaining how any changes in life circumstances may affect your taxes in the future, so that you are not caught off guard by an unexpectedly high tax bill or IRS penalties.

When to consider a tax projection:

You may benefit from this service if you anticipate one of the following events:

  • Significant increase in wages

  • Extended stay in the U.S.

  • Change in filing status (e.g., single ↔ married)

  • Retirement or withdrawal from a pension fund

  • Starting a business

  • Sale of real estate

  • Capital gains from selling stocks

  • Receiving severance pay

  • Relocating to another country

Turnaround time:

Approximately 15 business days.

What you will receive:

  • Draft Form 1040 based on your projected income

  • IRS estimated tax vouchers to help you pay on time and avoid underpayment penalties

Notes:

  • This is a quantitative service focused on calculations. If you are looking for strategic advice on how to minimize your projected tax liability, we recommend our separate tax planning consultation — a phone session tailored to tax-saving strategies.

  • The option to complete future year questionnaires is not immediately available in your TFX account to prevent any ambiguity. Please fill out a ''dummy'' Tax Questionnaire for 2005 with your projected income information.

For more information, please refer to Tax projection.


Prior return review

If your tax returns were prepared by someone other than TFX, they may contain errors, potentially leading to missed deductions, overpaid taxes, or exposure to IRS audits. Our experts can review your last three years of tax returns to ensure accuracy and compliance with IRS regulations.

What’s included in the prior return review:

  • Personal U.S. tax returns (Form 1040) for U.S. citizens and green card holders

  • Supporting forms such as 2555 (Foreign Earned Income Exclusion) and 1116 (Foreign Tax Credit)

What’s not included:

  • Non-resident returns (Form 1040-NR)

  • Business, trust, or partnership returns

  • Financial reporting (e.g., FBAR, Form 8938)

Purpose of the prior return review:
We aim to identify errors and missed deductions that may work in your favor. If we discover underpayment, we will explain the risks of leaving the return as-is, but we do not report anything to the IRS. The decision to amend is entirely yours. 

Pricing:

If an amendment is suggested, the review cost of $250 goes toward the amendment fee.

Turnaround time:
Approximately 10 business days.

Note on refunds:

  • Federal and Social Security/FICA refunds are not taxable (except for interest received).

  • State refunds are generally taxable.

  • The IRS typically processes amended return refunds within 3–4 months.

For more information, please refer to Check my tax return.


IRS letter review

TFX offers this service for those who have received a letter or notice from the IRS. We will review the letter, analyze your state of affairs, and explain in plain English how to dispute the IRS's position. Our findings will be presented to you, along with a recommended course of action to ensure that you receive fair treatment.

Pricing:

If an amendment is suggested, the review cost of $250 goes toward the amendment fee. Similarly, if IRS representation is necessary, the review cost will go towards the hourly fee ($200/hr), should you choose TFX to represent you.

For more information, please refer to IRS correspondence - How we can help.


IRS representation

TFX provides a professional IRS representation service billed hourly at $200/hr. Our agents will call and negotiate with the IRS on your behalf and:

  • Inquire about refund status (estimated time: 30 minutes).

  • Request a tax transcript (estimated time: one hour).

  • Discuss the case with the IRS agent and fax the requested documents (estimated time: one hour).

  • Write a letter to request a penalty waiver (estimated time: two hours).

For more information, please refer to IRS representation.


Expatriation services

Expatriating from the U.S. tax system, whether by renouncing U.S. citizenship or relinquishing a green card, is a complex process, especially if your net worth exceeds $2 million or you have had significant U.S. tax liabilities. In such cases, the IRS may classify you as a "covered expatriate", which can trigger a substantial exit tax. Even if your net worth is below $2 million, failing to file tax returns for the five years prior to your expatriation year can still result in being classified as a "covered expatriate".

What is required for a compliant expatriation:

To avoid covered expatriate status and its tax consequences, you must:

  • Hold another citizenship at the time of expatriation.

  • Be fully compliant with U.S. tax filings and FBARs for the 5 years preceding your expatriation year, and not owe any unpaid taxes from those years.

  • File a final U.S. tax return for the year of expatriation. For example, if you filed Form I-407 and formally abandoned your green card in 2025, your final return would be filed in 2026.

  • Submit Form 8854 to officially notify the IRS of your expatriation.

Our process:

We begin by evaluating your citizenship or residency status and confirming whether you are current on U.S. income tax and foreign asset reporting. If you are not compliant, we will recommend the most suitable option to catch up, either through the Streamlined Filing Procedures or Delinquent FBAR Submission Procedures, before preparing your final return.

Once all compliance issues are resolved, we will prepare and file your final tax return and Form 8854 to formally complete your expatriation process and terminate your U.S. tax resident status.

Turnaround time:

  • Compliant clients: Up to 1 month, depending on complexity.

  • Non-compliant clients: Up to 4 months.

Pricing:

The minimal total cost for preparing a final dual-status return (Forms 1040 & 1040NR) plus Form 8854 is ​$1,050:

Service

Fee

Dual-status return (Forms 1040 + 1040NR)

From $650 (additional fees may apply)

Form 8854 – Non-covered expatriate

$400

Form 8854 – Covered expatriate

Billed hourly at $200/hr (based on foreign asset complexity)

Notes:

  • Form 8854 is not required if you held a green card for fewer than 8 of the last 15 tax years.

  • Unlike citizens relinquishing their U.S. citizenship, green card holders may choose to file a resident return for the full tax year (starting at $450), which may be more beneficial. We will determine the best filing method during the review.

For details about filing requirements and pricing scenarios based on your filing history needs, please refer to Expatriation services.
