US Canada cross-border tax
Residency, treaty positions, FTCs, snowbirds, and US persons abroad.

Owner-level financial visibility
Cash flow, dashboards, monthly close, and lender-ready reporting.
Where clients usually need us
The small details matter most when tax systems overlap.
Most issues are not caused by one dramatic mistake. They usually come from a reasonable decision made in one country that creates a filing, reporting, payroll, or cash-flow issue somewhere else.
Canadian-owned US LLCs
A US LLC can look simple until Form 5472, pro-forma Form 1120, entity classification, treaty treatment, and Canadian reporting all need to line up.
NRIs and US persons with Indian assets
NRE, NRO, FCNR, demat accounts, Indian mutual funds, Form 8938, FBAR, PFIC Form 8621, and Form 1116 need a coordinated India-US view.
S-Corps and owner compensation
Form 1120-S is not just a return. Reasonable compensation, payroll filings, K-1s, basis, and state rules need documentation that can survive questions later.
US Canada residency and treaty positions
Snowbirds, US citizens in Canada, Canadian residents with US income, and cross-border founders often need treaty disclosures, foreign tax credits, and residency analysis.
Nonprofits and Form 990 compliance
We help 501(c)(3) organizations with Form 990, 990-EZ, 990-N, 990-T, bookkeeping cleanup, board reporting, and reinstatement after missed filings.
Businesses that need better numbers
Monthly close, QuickBooks cleanup, cash-flow forecasting, KPI dashboards, lender-ready reporting, and fractional CFO support help owners make decisions sooner.

Form 1120 vs Form 1120-S, Done Properly
Two corporate returns, two completely different tax outcomes. Picking the right entity structure and filing the right form is the highest-leverage decision a US business makes.
| Feature | Form 1120 (C-Corp) | Form 1120-S (S-Corp) |
|---|---|---|
| Entity type | C-Corporation, taxed as a separate legal entity | S-Corporation, pass-through entity for federal tax |
| Who pays tax | The corporation itself (21% flat federal rate) | Shareholders, through Schedule K-1 on Form 1040 |
| Double taxation | Yes (corporate tax + dividends taxed again) | No (single layer of tax at shareholder level) |
| Filing deadline | April 15 (or 15th day of 4th month after fiscal year end) | March 15 (or 15th day of 3rd month after fiscal year end) |
| Extension | Form 7004 extends to October 15 | Form 7004 extends to September 15 |
| Shareholder limit | Unlimited; foreign and corporate shareholders allowed | Maximum 100; US citizens or residents only; one class of stock |
| Reasonable compensation | Not specifically scrutinized for owner-employees | IRS hot button; misclassification triggers audits and back payroll taxes |
| QBI deduction (Section 199A) | Not available (entity-level tax) | Up to 20% deduction for qualifying shareholders |
| Best fit | VC-backed startups, businesses raising institutional capital, foreign owners | Profitable small businesses with US owner-operators, professional services firms |
Form 1120
US Corporation Income Tax Return
Used by C-Corporations to report income, deductions, gains, losses, and tax liability at the entity level. Required for every domestic C-Corporation regardless of whether the entity had activity during the tax year.
What we handle
- Federal Form 1120 with all required schedules (Schedule C, J, K, L, M-1, M-2, M-3)
- State corporate income tax returns and apportionment
- Form 5472 for foreign-owned US corporations
- Form 1120-W quarterly estimated tax calculations
- Form 1120-X amended returns and IRS notice resolution
- Section 1202 QSBS qualification analysis
When a C-Corp is the right call
You are raising venture capital, have foreign founders or shareholders, plan to reinvest profits at the corporate level rather than distribute, or expect to qualify for Section 1202 (QSBS) exclusion on exit.
Form 1120-S
US Income Tax Return for an S Corporation
Used by S-Corporations to report income, deductions, and credits that flow through to shareholders. The S-Corp itself generally does not pay federal income tax; instead, each shareholder receives a Schedule K-1 reporting their share of items to be included on their personal Form 1040.
What we handle
- Federal Form 1120-S with Schedules B, K, L, M-1, M-2, M-3
- Schedule K-1 preparation and distribution for all shareholders
- Reasonable compensation analysis using IRS safe-harbor methodology
- Stock basis and AAA (Accumulated Adjustments Account) tracking
- Form 2553 S-Corp election filing and late-election relief
- QBI deduction (Section 199A) optimization for shareholders
When an S-Corp is the right call
You are a profitable US-based small business with US-resident owner-operators, want pass-through taxation, and can support a defensible reasonable compensation level. Self-employment tax savings versus a Schedule C is typically the deciding factor.
The S-Corp Reasonable Compensation Trap
S-Corporation owner-employees must be paid a reasonable salary subject to FICA before taking distributions. The IRS uses tools like RCReports, BLS wage data, and industry benchmarks to challenge low salaries. A failed reasonable comp determination reclassifies distributions as wages, triggering back payroll taxes, penalties, and interest plus a guaranteed audit on future returns.
Every Form 1120-S we file includes a written reasonable compensation memo with defensible methodology, role analysis, geographic adjustment, and time allocation. If you ever get a letter from the IRS, you have a documented position ready to defend.
US Canada Cross-Border Taxation
Whether you are a Canadian resident with US income, a US citizen living in Canada, or a snowbird splitting time between Vancouver and Phoenix, the rules are the same: file in both countries, claim the treaty, avoid double tax.
Canadians with US Income or US Property
For Canadian residents earning US income, owning US real estate, or operating US LLCs and corporations.

Frequently Asked Questions
Questions we hear most often from cross-border founders, NRIs, and small business owners.
Do Canadians who own a US LLC need to file a US tax return?
Yes. A Canadian resident who owns a US single-member LLC must file Form 5472 along with a pro-forma Form 1120 each year. Failure to file carries an automatic $25,000 penalty per year per entity. If the LLC has elected to be treated as a C-Corporation it files a full Form 1120; if elected as an S-Corporation it is not eligible because S-Corps cannot have nonresident alien shareholders. We bring foreign-owned LLCs into compliance and advise on whether a C-Corp election, restructuring, or treaty positioning is the right move.
What is the difference between Form 1120 and Form 1120-S?
Form 1120 is the US Corporation Income Tax Return filed by C-Corporations, which pay federal tax at the entity level (flat 21%). Form 1120-S is the US Income Tax Return for an S Corporation, which is a pass-through entity where income, deductions, and credits flow to shareholders via Schedule K-1 and are reported on each shareholder's personal Form 1040. Form 1120 is due April 15. Form 1120-S is due March 15. See our Form 1120 vs 1120-S comparison section above for a full breakdown.
Do NRIs living in India need to file US tax returns?
NRIs who are US citizens, Green Card holders, or who meet the Substantial Presence Test must file Form 1040 and report worldwide income each year, regardless of where they live. NRIs with US-source income such as rental property, US dividends, or US capital gains generally file Form 1040-NR. Indian bank accounts (NRE, NRO, FCNR) over $10,000 in aggregate at any point during the year trigger FBAR filing. Indian mutual funds are classified as PFICs by the IRS and require a separate Form 8621 for each fund held.
When should a small business hire a Fractional CFO?
Typical triggers include revenue between $1M and $20M, preparing for a capital raise or acquisition, complex multi-entity or multi-state structures, persistent cash flow problems, or needing a real financial model and forecast for the first time. Fractional CFO engagements run roughly $3,000 to $12,000 per month, which is about 25% to 40% of the cost of a full-time CFO (typically $200,000 plus in total comp). For most companies under $20M in revenue, fractional delivers better value because you only pay for the senior expertise you actually need.
What is FBAR and who must file it?
FBAR stands for Report of Foreign Bank and Financial Accounts (FinCEN Form 114). Every US person (citizen, resident, entity) must file FBAR if the aggregate value of all foreign financial accounts exceeded $10,000 at any point during the calendar year. Critically, the threshold is the maximum balance at any point in the year, not the year-end balance. FBAR is filed separately from your tax return through the BSA E-Filing System. Penalties for non-willful failure to file start at $10,000 per report.
What happens if my nonprofit missed three years of Form 990?
Three consecutive years of missed Form 990, 990-EZ, or 990-N triggers automatic revocation of tax-exempt status under IRC 6033(j). To regain exempt status you must file Form 1023 (or 1023-EZ if eligible) along with a reasonable cause statement explaining why the filings were missed, plus all delinquent Form 990 returns. Donors lose deductibility for contributions made during the revoked period unless retroactive reinstatement is granted. We handle the full reinstatement process and have a strong success rate with reasonable cause acceptance.
What does your engagement actually cost?
Fees are flat per engagement, never hourly billing surprises. Typical ranges: cross-border individual returns from $800; Form 1120 and 1120-S filings from $1,500; Form 990 filings from $1,200; NRI compliance bundles (1040 plus FBAR plus FATCA plus PFIC) from $1,800. Fractional CFO engagements run $3,000 to $12,000 per month depending on scope. We provide a flat-fee proposal in writing after the discovery call so you know exactly what you are paying before you commit.
Do you work alongside our existing accountant?
Often, yes. We frequently coordinate directly with Indian CAs for Form 67 and DTAA positioning, with Canadian CPAs for T1 and corporate filings on the Canadian side, and with US bookkeepers and controllers on monthly close. If your existing accountant is reactive and compliance-only, we add a strategic layer. If they are already strategic, we complement on the cross-border specialty. We will tell you honestly whether you need to replace anyone or just add specialized capacity.
