The True Cost of Running a US Company as a Non-US Founder: Singapore Compared

Quick Answer

Running a US company as a non-US founder costs significantly more than most founders expect. Between federal corporate tax, state taxes, franchise tax, registered agent fees, CPA costs, FBAR/FATCA reporting and multi-state sales tax compliance, the annual cost ranges from US$5,000 to US$15,000+ before the company earns a dollar. Singapore's equivalent is S$2,000 to S$5,000 with a single regulator and a single tax return. Savvy Platform helps founders incorporate in Singapore through SavvyStart, with nominee director, company secretary and compliance support included.

Why This Article Exists

The cost of incorporating in Delaware is low. The cost of running a Delaware entity as a non-US founder is not. Most guides focus on setup. This article focuses on what happens after.

The hidden costs of a US entity fall into four categories:

• Federal and state tax compliance
• Delaware-specific obligations
• International reporting requirements (FBAR, FATCA, Form 5472)
• Multi-state sales tax complexity

Each of these adds annual cost that does not exist in Singapore.

Line-by-Line Annual Cost: US vs Singapore

US Annual Costs (Delaware C-Corp, non-US founder)

Cost item	Annual amount	Notes
Federal corporate tax return (Form 1120)	US$2,000-5,000 (CPA fees)	Required even with zero revenue
Delaware franchise tax	US$400-2,000+	Minimum $400 (Assumed Par Value method), scales with shares and assets
Delaware annual report filing	US$50	Required annually
Registered agent (Delaware)	US$100-300	Mandatory, physical address in Delaware
State income tax returns	US$500-2,000 per state	Required in every state where the company has nexus
Sales tax compliance	US$500-3,000+	Required in states where economic nexus is triggered
Form 5472 (foreign-owned LLC)	US$500-1,500 (CPA fees)	Mandatory for foreign-owned entities, $25,000 penalty if missed
FBAR (FinCEN 114)	US$300-800	Required if US person has foreign accounts over $10,000
Estimated quarterly tax payments	US$0-variable	Four payments per year if tax liability expected
Bookkeeping (US GAAP)	US$1,500-5,000	US-standard bookkeeping required for CPA filings
Total annual minimum	US$5,000-15,000+	Before earning revenue, before state expansion

Singapore Annual Costs (Pte Ltd, foreign founder)

Cost item	Annual amount	Notes
Corporate tax return (Form C-S)	S$500-1,500	Simplified form for companies under S$5M revenue
ACRA annual return	S$60	One filing
Company secretary	S$300-800	Handles all statutory admin
Nominee director	S$1,450-3,000	Removable once founder gets Employment Pass
Registered address	S$200-500	Provided by CSP
Bookkeeping	S$300-1,200	Simpler requirements, no US GAAP
Total annual	S$2,000-5,000	Single regulator, single tax return

The annual cost difference is approximately US$3,000 to US$10,000+ per year, every year, with the gap widening as the US company operates in more states.

The Penalties That Catch Founders

US filing obligations carry penalties that are disproportionately high for small companies.

Form	Penalty for late/missed filing	Who it applies to
Form 5472	US$25,000 per foreign shareholder	Foreign-owned US entities
FBAR (FinCEN 114)	US$10,000 per account (non-willful), up to US$14,000 inflation-adjusted in 2026	US persons with foreign accounts over US$10,000
Form 5471	US$10,000 per foreign subsidiary + 5%/month of unpaid balance	US persons with foreign corporate interests
Form 1120 (federal tax return)	5%/month of unpaid tax, up to 25%	All US C-Corps
Delaware franchise tax	US$200 + 1.5%/month on outstanding balance	All Delaware entities

A non-US founder who misses a Form 5472 filing faces a US$25,000 penalty. This is not scaled to company size. A dormant LLC with zero revenue owes the same penalty as a Fortune 500 company.

Singapore has no equivalent penalty regime for foreign founders. ACRA late filing fees are S$300 for a late annual return.

The Multi-State Sales Tax Problem

This is the cost most founders do not see coming.

The US has no federal sales tax. Instead, 45 states and the District of Columbia each have their own sales tax rules, rates and thresholds. Since the 2018 South Dakota v. Wayfair Supreme Court ruling, states can require sales tax collection from out-of-state sellers who exceed economic nexus thresholds (typically US$100,000 in sales or 200 transactions).

For an e-commerce or SaaS company selling across the US:

Challenge	Impact
Different tax rates per state	Rates range from 0% to over 10%
Different nexus thresholds	Most states: $100,000 or 200 transactions
Different rules for SaaS/digital products	Some states tax SaaS, others do not
Registration required per state	Each state has its own registration process
Filing frequency varies	Monthly, quarterly or annually depending on state and volume
Audit exposure	Each state can audit independently

A US company selling SaaS across 20 states may need to register, collect and remit sales tax in each of those states, file returns on different schedules, and track rate changes. This is a compliance operation, not just a tax line item.

Singapore has one GST rate (9%), one registration threshold (S$1M turnover), one filing schedule (quarterly) and one tax authority (IRAS). For most startups, GST registration is not even required.

It is important to mention that sales tax in the US and GST in Singapore are applicable to local sales only. A Singapore company’s sales to US-based customers are not subject to GST, as these sales occur outside Singapore.

The CPA Cost Trap

US tax compliance for foreign-owned entities requires a US-qualified CPA. This is not optional.

Filing	CPA cost range	Frequency
Form 1120 (C-Corp federal return)	US$2,000-5,000	Annual
Form 5472 (foreign-owned entity)	US$500-1,500	Annual
State corporate tax returns	US$500-2,000 per state	Annual per state
Sales tax returns	US$200-500 per state per filing	Monthly/quarterly/annual per state
Estimated quarterly payments	US$200-500 per quarter	4x per year
FBAR filing	US$300-800	Annual

A non-US founder running a Delaware C-Corp with operations in two states can easily spend US$5,000-8,000 per year on CPA fees alone. This is before paying any actual tax.

Singapore accounting and tax filing for a small Pte Ltd costs S$800 to S$2,500 per year. One filing, one regulator, one accountant engagement.

What Non-US Founders Often Discover Too Late

Surprise	What happens
Form 5472 exists	Foreign-owned US entities must file even with zero revenue. $25,000 penalty per missed filing.
Delaware franchise tax scales	Authorizing millions of shares (standard for VC-track startups) can trigger $10,000+ franchise tax under the Authorized Shares method. The Assumed Par Value method reduces this but requires careful calculation.
Section 174 changed R&D expensing	Since 2022, US companies must capitalise and amortise R&D expenses over 5 years (domestic) or 15 years (foreign) instead of deducting immediately. This increases taxable income for R&D-heavy startups.
Sales tax nexus is retroactive	If a company triggers nexus in a state and does not register, back taxes, penalties and interest can apply retroactively.
FBAR penalties are per account	A founder with 3 foreign bank accounts who misses FBAR faces up to US$42,000 in non-willful penalties.
US CPA is mandatory	Singapore, UK or Australian accountants cannot file US corporate tax returns. A US CPA is required annually.

The Real Comparison: Year 1 Through Year 3

Cost category	US (Delaware C-Corp, Year 1-3)	Singapore (Pte Ltd, Year 1-3)
Setup cost	US$500-1,000	S$500-2,000
Annual compliance (per year)	US$5,000-15,000	S$2,000-5,000
3-year total compliance	US$15,000-45,000	S$6,000-15,000
Corporate tax on $200K profit	~US$42,000 (21% federal)	~S$8,375 (after SUTE exemptions)
Dividend withholding	30% (or treaty rate)	0%
3-year total cost (compliance + tax)	US$57,000-87,000+	S$14,375-23,375

Over three years, a non-US founder running a Delaware C-Corp can spend US$57,000 to US$87,000+ in compliance costs and tax. The same founder in Singapore spends S$14,375 to S$23,375 total.

When the US Cost Is Justified

The US compliance burden is justified when:

• 70%+ of revenue comes from US customers
• The company needs US regulatory licensing
• Lead investors require a Delaware C-Corp
• The founder plans to relocate to the US
• The company intends a US IPO

If none of these apply, the US cost structure is overhead without a corresponding benefit.

How Savvy Platform Keeps Costs Predictable

Savvy Platform's SavvyStart package is designed to eliminate the cost unpredictability that non-US founders face with US entities.

Savvy Platform’s SavvyStart package includes:

• Company incorporation for a flat fee
• Local Nominee director service for one year
• Company secretary and registered address
• Bank account setup support
• Ongoing compliance and annual filing management
• No multi-state registration, no franchise tax, no Form 5472

Conclusion

The true cost of running a US company as a non-US founder is US$5,000 to US$15,000+ per year in compliance alone, before any tax is paid. Penalties for missed filings start at US$10,000 and reach US$25,000 per form. Singapore achieves the same corporate credibility with a single regulator, a single tax return and annual costs of S$2,000 to S$5,000. Savvy Platform makes Singapore the obvious choice for cost-conscious international founders.

FAQ

How much does it cost to maintain a Delaware C-Corp per year?

Annual compliance costs for a non-US founder range from US$5,000 to US$15,000+, including CPA fees, franchise tax, registered agent, state tax returns and international reporting (Form 5472, FBAR).

What is Form 5472?

Form 5472 is a mandatory IRS filing for US entities that are 25%+ foreign-owned. It must be filed even if the company has zero revenue. The penalty for missing this filing is US$25,000 per foreign shareholder.

What is the FBAR?

The FBAR (FinCEN 114) requires US persons to report foreign bank accounts exceeding US$10,000 in aggregate. The non-willful penalty for missing an FBAR is approximately US$14,000 per account (inflation-adjusted for 2026).

Is Singapore compliance really that much simpler?

Yes. Singapore has one regulator (ACRA), one tax authority (IRAS), one annual return, one corporate tax filing, and no equivalent of Form 5472, FBAR, sales tax nexus or state-level reporting.

Do I need a US CPA for a Delaware company?

Yes. US corporate tax returns (Form 1120) and international information returns (Form 5472, 5471) require a US-qualified CPA. Singapore or foreign accountants cannot file these forms.

What happens if I authorize too many shares in Delaware?

Delaware franchise tax can scale to US$10,000+ under the Authorized Shares method if you authorise millions of shares (common for VC-track startups). The Assumed Par Value method reduces this, but requires careful calculation each year.

Can I avoid US sales tax if my company is in Delaware?

No. Delaware has no state sales tax, but if your company sells to customers in other states and triggers economic nexus (typically US$100,000 or 200 transactions), you must collect and remit sales tax in those states.

Does Savvy Platform include all annual compliance?

Yes. The SavvyStart package includes a company secretary, ACRA filing, a registered address, and compliance management for a predictable annual cost with no hidden fees.
