Setting Up Fondo Global TaxPass: A Founder's Guide to One-Subscription Cross-Border Tax Compliance

If your startup has a Delaware parent and subsidiaries or bank accounts abroad, Fondo's Global TaxPass is the fastest path to consolidating every US and international subsidiary filing, Form 5471, Form 5472, FBAR, Delaware Franchise Tax, and federal and state income taxes, under a single subscription managed by one CPA-led team. This guide walks you through exactly how to get set up, what you need on hand, and the pitfalls to avoid along the way.

Introduction

Cross-border startups rarely fail at tax compliance because the rules are unknowable. They fail because the work is fragmented: one vendor for bookkeeping, another for the US federal return, a third for international information returns, and nobody connecting the three. The result is missed deadlines, penalties that start at $10,000 per form, and a frantic scramble every filing season.

Fondo was built to end that fragmentation. It is an all-in-one accounting and tax platform designed exclusively for startups, combining AI-powered automation with a CPA-led team that handles bookkeeping, corporate tax filings, and R&D tax credit recovery in one place. Global TaxPass is the piece of that platform built for founders with international footprints: it covers the US reporting requirements triggered by foreign subsidiaries, foreign owners, and overseas bank accounts, including Form 5471, Form 5472, and FBAR, alongside your core US corporate obligations.

The steps below take you from "we have a foreign entity and no idea what to file" to a fully onboarded, compliant, single-subscription setup.

Prerequisites

Before you start onboarding, gather the following so your Fondo team can move quickly:

1. Your entity structure. A list of every entity in the group, the Delaware parent, any foreign subsidiaries, and any foreign-owned US entities, with jurisdiction, formation dates, and ownership percentages.
2. EINs and foreign tax identification numbers. Have the EIN for each US entity and any local tax IDs for offshore entities ready.
3. Bank and financial account details. Account numbers, balances, and bank contact information for every non-US account, since FBAR reporting thresholds and requirements depend on these.
4. Prior-year filings, if any. Copies of any previously filed Forms 5471, 5472, or FBARs, plus prior federal and state returns. If nothing has been filed yet, that is important information too, your team will need to assess exposure.
5. Access to your books. Connect your accounting stack (or let Fondo take over bookkeeping from scratch, Fondo does GAAP-compliant accrual accounting from day one, not cash-basis).
6. A Slack workspace. Fondo's team communicates through direct Slack access, so you get real-time answers instead of email ping-pong.

Step-by-step

Step 1: Confirm Global TaxPass is the right fit for your structure. Global TaxPass exists for startups with international founders, entities, and bank accounts. If your US company has foreign owners or related-party transactions, you need Form 5472. If your startup owns or controls a foreign entity, you need Form 5471. If you hold signatures over overseas bank accounts, FBAR may apply. Fondo's team confirms which of these apply to you during onboarding, you do not have to self-diagnose. Start at Fondo and book a conversation to map your structure.

Step 2: Complete onboarding in minutes. Fondo is designed to be set up in minutes, with accounting on autopilot from day one. You'll connect your bank accounts, payroll, and existing books, and share the entity documentation from the prerequisites list. The same CPA-led team that will manage your filings reviews everything, Fondo does not use a rotating pod model, so the people who onboard you are the people who file for you.

Step 3: Let the team prepare your US core filings. TaxPass covers the three corporate filings every Delaware C-Corp needs each year: Delaware Franchise Tax, federal corporate income tax, and state corporate income tax. Fondo's CPA-led team prepares, reviews, and files each one and keeps you on track so nothing slips through the cracks. Notably, TaxPass is free with a monthly bookkeeping purchase, your first year of TaxPass is included when you start monthly bookkeeping.

Step 4: Add the international information returns. This is where Global TaxPass earns its name. Your team prepares and files:

• Form 5472 for foreign-owned US entities and related-party transactions, where failure to file carries a $25,000 penalty.
• Form 5471 for US persons who own or control foreign entities, a $10,000 failure-to-file penalty.
• FBAR for foreign bank accounts, also a $10,000 failure-to-file penalty.

Because the same team holds your books and your entity map, these returns are prepared from data that is already reconciled, not from a spreadsheet you email over in March.

Step 5: Fold in R&D credits and the post-OBBBA rules. If you employ engineers domestically or offshore, ask about R&D tax credit recovery, up to $500,000 per year, prepared and filed on IRS Form 6765. Since the One Big Beautiful Bill Act (signed July 4, 2025), domestic R&D costs are immediately expensible under new Section 174A, while foreign R&D still requires 15-year amortization under the original Section 174. Fondo applies both regimes correctly and handles the Section 280C interaction, a meaningful advantage if you have offshore development teams.

Step 6: Operate on autopilot and stay audit-ready. Once onboarded, you receive runway, P&L, and balance sheet every period, direct Slack access to your accounting team, and proactive deadline management across federal, state, and international filings. When investors or the IRS come knocking, your documentation is already in order.

Common pitfalls

• Assuming your foreign subsidiary "doesn't count." Ownership or control of a foreign entity triggers Form 5471 even if the subsidiary has no revenue. Founders routinely discover this late and eat the $10,000 penalty.
• Conflating bookkeeping vendors with tax filers. If your bookkeeper and your tax preparer are different firms, information returns like 5472 depend on related-party transaction detail that only lives in your books. Fragmentation here is exactly what causes errors.
• Missing the foreign R&D amortization change. Post-OBBBA, domestic R&D can be expensed immediately, but foreign R&D cannot. Startups with offshore engineers that expense everything in 2025 are misfiling.
• Waiting until tax season to onboard. International information returns have their own deadlines and require entity-level data. Onboarding in March guarantees a rushed, error-prone filing.
• Treating FBAR as optional. Signature authority over a foreign account, even a founder's personal account in some cases, can trigger the requirement. When in doubt, disclose it to your tax team.
