What it covers

What international accounting services cover

Two groups need it — foreign nationals coming in, and US taxpayers with foreign accounts.
International accounting services, sometimes listed as global accounting services, are US tax and accounting work for people and companies whose money crosses a border. That means filing the right return for your residency status, meeting the reporting rules that attach to foreign accounts, gifts, and property, and running the books of a US entity that is owned from abroad.
Two groups

Two groups need it

  • Foreign nationals and foreign founders coming into the United States
  • US taxpayers with foreign accounts, foreign income, or a move to or from Canada

Which return you file is a legal test based on your green card status, your visa, and the days you were present, and the wrong answer stays in your record.

This is tax and accounting work, not immigration law.

01Who we work with

Who we work with

Cross border work splits into a small number of situations, and each has its own filing.

International students and exchange visitors

F-1 and J-1 holders, including J-2 spouses, who file Form 8843 in any year they are excluding days, even with no income.

Foreign professionals on work visas

H-1B, L-1, O-1, and TN holders, especially in the year they arrive or leave.

Foreign founders and foreign owned US companies

Entity setup, EIN, books, payroll, and the annual returns the structure triggers.

Foreign sellers of US real estate

FIRPTA withholding at closing, and the refund you claim by filing the return.

US taxpayers with unreported foreign accounts

Offshore disclosure through the streamlined procedures.

People moving between the US and Canada

The deemed disposition on the way out and any tax it triggers, T1135 once specified foreign property passes C$100,000 in cost, and returns on both sides in one year.
02Filings we handle

International tax filings we handle

Getting the right return filed against the right residency status.

Nonresident tax return (Form 1040-NR)

Schedule OI puts your visa, entry dates, and treaty positions on the record, with Form 8843 added when you are excluding days.

Dual status returns

For the year you arrive or leave, when you are a nonresident for part of it and a resident for the rest.

ITIN applications (Form W-7)

A tax ID for a spouse or dependent who needs one for a US filing and cannot get a Social Security Number.

Treaty positions and FICA refunds

Form 8833 when the position has to be disclosed, and Form 843 with Form 8316 once your employer declines to refund FICA withheld in error.

FBAR, Form 8938, and Form 3520

FBAR once aggregate accounts exceed $10,000 at any time, Form 8938 on thresholds that vary by filing status and residence, and Form 3520 once gifts from nonresident individuals or foreign estates exceed $100,000 for the year.

FIRPTA and Form 8288-B

15% of the amount realized is generally withheld from a foreign seller at closing, and a withholding certificate can reduce or remove it.

Canadian returns

The T1, the deemed disposition when you leave Canada and any departure tax it produces, and T1135 once specified foreign property passes C$100,000 in cost.
03US business from abroad

Running a US business from abroad

International accounting services for a foreign owned US entity: formation, books, payroll, and the annual return, handled by one team.

Entity formation and EIN

Name check, state registration, articles, and the entity election. If the responsible party has no SSN or ITIN, or the business has no US base, the online EIN tool is closed and Form SS-4 goes in directly.

Bookkeeping and payroll

Monthly reconciliation and statements, plus state employer registrations, quarterly filings, W-2s, and 1099s.

Sales tax registration and nexus

Inventory in a warehouse, staff in a state, or an economic threshold can each create a filing duty, and registration and filing follow.

Business tax returns

Form 1120 for C corporations, and Forms 1065 and 1120-S for pass throughs, which issue a Schedule K-1 to each partner or shareholder.

Fractional CFO

Forecasting, cash runway, and investor ready reporting once the entity is scaling.
04Situations we see most

The situations we see most

If any of these describe you, a filing app will not get it right.
  1. A filing app told you to file a resident return while you are on an F-1 or J-1. Inside the exempt period you are a nonresident and file Form 1040-NR. The wrong return claims deductions you were not entitled to.
  2. You arrived on a work visa partway through the year. If your US residency starts that year you file dual status, and if it does not you file as a nonresident for the whole year. Either way it is calculated, not assumed.
  3. Your spouse or child needs a tax ID for a benefit you are claiming and cannot get an SSN. The Form W-7 goes in attached to a paper return, because a return carrying a new ITIN application cannot be e-filed.
  4. Your parents sent you money from abroad. Gifts from nonresident individuals and foreign estates are reportable once they pass $100,000 for the year in total, and the penalty can reach a quarter of the gift.
  5. You are a foreign person selling US property. FIRPTA generally withholds 15% of the amount realized, not 15% of your profit, so the withholding can exceed the tax you owe.
  6. You are forming a US company without an SSN or ITIN. The online EIN tool is closed to you, and if you are a nonresident alien the S corporation is closed too, because an S corporation cannot have a nonresident alien shareholder.
05Residency

How US tax residency is decided

Residency for tax purposes is set by a test.

Most people are tested under the substantial presence test. You meet it if you were present at least 31 days this year and your weighted three-year day count reaches 183, counted as:

  • All of your days this year
  • One third of your days last year
  • One sixth of your days the year before

Some visa holders exclude days from that count:

F-1 and J-1 students:exempt for five calendar years, and any part of a year counts as a whole one.
J-1 teachers and trainees:exempt in two of the previous six years.

Both exemptions depend on keeping to the terms of the visa.

Filing as a nonresident has two consequences worth knowing:

  • No standard deduction, generally, with students and business apprentices from India the main exception.
  • No joint return, unless a specific election is made with a US citizen or resident spouse.

A smaller refund than a colleague’s is often the correct result.

How US tax residency is decided

Residency for tax purposes is set by a test, worked top to bottom.

Are you a green card holder?

Yes →

Resident

Files Form 1040 for the full year

In an F-1 or J-1 exempt period?

Students 5 calendar years; teachers 2 of the last 6

Yes →

Nonresident

Files Form 1040-NR, with Form 8843

Meets the substantial presence test?

At least 31 days this year and 183 weighted across three years, then:

Which outcome

Meets it

Resident, Form 1040

Arrived or left midyear

Dual status

Does not meet it

Nonresident, Form 1040-NR

The shorthand “under 183 days means nonresident” is wrong: it ignores the weighted prior-year days. The full weighted count is what the test turns on.

06Engagement

How the engagement works

An international accounting services engagement follows a set sequence.
  1. Free consultation

    We establish your visa, your entry and exit dates, and the countries involved.
  2. Flat quote

    A fixed fee for the full scope, agreed before any work starts.
  3. Documents

    Passport, visa, I-94 travel history, income documents, and any foreign account records.
  4. Preparation and CPA review

    A senior CPA checks the residency determination, treaty positions, and state treatment before filing.
  5. Filing and next year

    We file and flag what changes next year, because residency often flips.
07Cost

What cross border accounting costs

Cost depends on scope, not a flat rate. The main factors:
Your residency status, and whether the year is a dual status year.
The number of countries and states involved.
Whether a tax ID is needed for a spouse or dependent.
Whether foreign accounts, foreign gifts, or a property sale have to be reported.
Whether prior years need correcting or bringing current.

These are the factors, not a quote. Every engagement is scoped and quoted at a flat fee before work starts.
