Sole Proprietor vs Global LLC: The Tax and Fee Iceberg Behind Your Business Structure
Executive industry analysis
Creators who earn from international customers often ask whether a local sole proprietorship or an overseas company would leave them with more money. The headline question is usually about the tax rate, and a lower rate is attractive. But the tax rate is only one line of a longer bill. Payment providers take a percentage, money moves between currencies at a spread, an accountant has to file, a registered agent has to be paid, and the structure itself has to be formed and maintained. The right comparison is the amount you keep at the end of the month, not the rate on the first page.
The structure of the problem is a revenue stream passing through several filters. First come payment and conversion costs, which scale with revenue. Then come fixed costs, which do not scale at all: compliance, bank fees and the set-up cost spread across months. Last comes tax, which is charged on what remains after deductible costs. This means a structure with a lower rate can still lose to a simpler one when revenue is small, because fixed costs eat a larger share, and can win clearly when revenue is large. The break-even revenue is the figure that matters.
The domino model follows the cascade. Payment drag shows how much of each dollar is lost to fees and currency conversion. Fixed burden shows what compliance and set-up take from revenue. What remains, after deductible costs, is the taxable profit. The total burden combines fees, costs and tax into one percentage of revenue, which is the cleanest number for comparing two structures. The last box shows take-home profit for the month. A small rise in fixed cost can turn a profitable month into a losing one for a small business.
The iceberg separates the costs people talk about from those they forget. Above the waterline sit tax and payment fees, which every owner knows. Below it sit currency conversion, the accountant and filing fees, the set-up cost spread over time and the bank and wire charges. These hidden items often equal a third or more of the visible ones. This model is general and educational. Tax rules differ by country and change, and no simulator can replace advice from a qualified professional about your situation.
Formula and methodology blueprint
The model works on one month and is educational, not tax advice. Payment fees and currency costs are percentages of revenue. Compliance is a fixed monthly amount and set-up cost is spread over twenty-four months. Bank and wire fees are a small fixed monthly amount. Deductible costs reduce taxable profit, and tax is the effective rate times taxable profit, with no tax when profit is negative. Take-home profit is revenue minus costs minus tax. Scenario B applies example assumptions for an overseas LLC to the same inputs.
- Payment and conversion cost
- F = revenue × (payment fee + currency cost) + bank fees
- Costs that scale with revenue, plus a small fixed bank charge.
- Fixed burden
- B = compliance + set-up ÷ 24
- Monthly cost of staying compliant and of having formed the structure.
- Taxable profit
- T = max(0, revenue − F − B)
- What remains to be taxed after deductible costs.
- Tax
- tax = T × effective tax burden
- Tax at the effective rate you enter. Check current rules for your situation.
- Net take-home
- Net = revenue − F − B − tax
- The monthly result. The breaking point is where this reaches zero.
- Total burden
- (revenue − Net) ÷ revenue
- Share of revenue taken by fees, costs and tax together, the best number for comparing two structures.
Cascading elasticity
Revenue is the most elastic input, because fixed costs stay put while revenue changes: at low revenue they take a large share and at high revenue a small one. Effective tax burden scales directly with profit. Compliance cost is linear but decides the floor for small businesses. Payment fees and currency costs scale with revenue, so a small percentage difference becomes a large amount at scale.
Three real-world case studies
Bootstrapped starter
A small side income with a simple structure
A new creator earns a couple of thousand dollars a month, pays a low effective tax burden and keeps compliance to a minimum. Fees are modest and set-up was cheap, so most revenue is kept. Load it to see how quickly fixed costs matter when revenue is small.
Scaling mid-market
A larger creator business with an accountant
A creator business earns forty thousand dollars a month, pays a higher effective rate, hires an accountant and has spent more on set-up. Fixed costs are tiny compared with revenue, so rates and fees dominate. Load it to see why percentage differences matter more at scale.
Black-swan crisis
A heavy structure on small revenue
A creator with a small income has formed an expensive structure with large monthly compliance costs, high fees and costly currency conversion. Costs exceed revenue and the month ends negative. Load it to see which cost, usually compliance, makes the structure unaffordable.

Variables and levers
Monthly revenue
Total monthly income from customers, platforms and sponsors, before any fees or taxes.
Lever: Raise prices or add a higher-margin offer; fixed compliance costs weigh far less on larger revenue.
Effective tax burden
Your overall effective rate on profit in this structure, including income tax and any social contributions. Check current rules for your situation.
Lever: Ask a qualified local adviser which rates and allowances apply to you, and check current rules before choosing a structure.
Payment processing fee
Percentage taken by card, platform and payment providers on each sale, including fixed fees averaged in.
Lever: Compare payment providers and move large customers to bank transfer or annual billing where fees are lower.
Currency conversion and transfer cost
Spread and transfer cost when money is converted or moved between currencies and countries.
Lever: Keep income in the currency you earn it where possible, and convert in larger, planned batches at a transparent rate.
Monthly compliance cost
Accountant, bookkeeping, filings, registered agent and any annual fees, averaged per month.
Lever: Get fixed-fee quotes from several accountants and automate bookkeeping to keep the monthly cost predictable.
Set-up and formation cost
One-off cost of registration, address, legal help and bank accounts, spread over two years in the model.
Lever: Price the full set-up before you commit, including legal help, address and bank accounts, and avoid unneeded extras.

Mistakes to avoid
- Choosing a structure from the headline tax rate alone. Fees, currency costs and compliance can erase a lower rate when revenue is small.
- Forgetting that tax rules differ by country and change. A figure copied from a forum is not a substitute for current rules and a qualified adviser.
- Ignoring currency conversion. A one percent spread on every payment is a large annual amount that never appears as a line item.
- Treating set-up as a one-time detail. Formation, address and bank costs have to be recovered from profit, and a small business may take a long time to do so.
Frequently asked questions
Is an overseas LLC always cheaper in tax?
No. Tax outcomes depend on where you live, where the company is formed and how profit is paid out. This model lets you enter an effective rate but does not decide what applies to you. Seek qualified professional advice and check current rules.
Why do fixed costs matter so much?
Compliance and set-up costs do not shrink when revenue falls, so for a small business they can outweigh any saving from a lower rate. The model shows the revenue at which a structure starts to pay.
How do I find my breaking point?
Press Find my breaking point. The tool pushes each input towards its worse end in a thousand steps and reports the value at which monthly profit reaches zero, ranked by how close each one is.
What does Scenario B assume?
It uses example assumptions for an overseas LLC: a 20 percent lower effective tax burden, 15 percent lower payment fees, 30 percent higher currency cost, 140 dollars more monthly compliance and 700 dollars more set-up cost. Change the inputs to match your own quotes.
Does the model cover every tax?
No. It uses one effective rate and does not model personal taxes on distributions, indirect taxes, anti-avoidance rules or reporting duties. These vary by country and change over time.
How accurate is this?
It is an educational planning model with the assumptions stated above. It is not tax, legal or financial advice. Replace the inputs with figures from your adviser and check them against current rules.
