US LLC for software developers and SaaS founders: the complete guide

0% federal in the US on 50. Software developers and SaaS founders are among the best fits for a US LLC structure. Here is how it transforms your business.

Software developers and SaaS founders are among the best fits for a US LLC structure. If your product is 100% digital and your clients are global, this is why this structure is ideal.

Why software and LLCs are a perfect match

Your product is 100% digital. Your clients are worldwide. Your revenue can come from anywhere. A US LLC removes the geographic constraints of operating as an individual or local company.

Global payments without friction

Whether you're billing a startup in San Francisco, an agency in London, or a company in Singapore:

Stripe US processes cards from 195+ countries
ACH for US clients (free via Mercury)
Wire transfers for international clients ($0 on Mercury)
All settlement in USD into your Mercury account

Platform integrations

Every developer tool assumes a US entity:

GitHub Sponsors: Pays to US bank accounts
AWS / Google Cloud / Azure: Direct billing to your LLC
App Store / Google Play: Payments go to your US account
Stripe Atlas: Many SaaS founders start here, but Exentax offers a more complete and personalized service

SaaS-specific tools

Stripe Billing for subscriptions

If your business model is subscriptions, Stripe Billing is your best friend:

Automatic recurring charges
Plan management, upgrades, downgrades
Dunning management (failed payment recovery)
Automatic tax calculation for certain countries
Clear fees: 2.9% + $0.30 per US transaction

DoDo Payments for B2C global sales

If your SaaS sells directly to end consumers in multiple countries, DoDo Payments acts as Merchant of Record: it calculates, collects, and remits VAT/GST for each country automatically. You don't need to register for VAT in 40+ different jurisdictions.

Slash and Wallester: treasury and expense control

Slash so your accumulated MRR generates yield while you decide when to distribute. ideal for SaaS with predictable recurring revenue
Wallester for virtual corporate cards: one for AWS, another for GitHub, another for team tools. granular control without sharing your debit card

Specific use cases

Freelance developer

You work for US startups and European companies. With your LLC:

Invoice as a US business (different psychological impact than as an individual)
Access US market job boards and contract opportunities that require a US entity
Receive all payments in USD without conversion hassle
Professional credibility with CTO-level clients

SaaS founder

You have a product with monthly subscriptions. With your LLC:

Stripe Billing for subscription management (recurring charges, trial management, dunning)
App Store and Google Play pay directly to Mercury
Intellectual property (your code) is a documented LLC asset
Investor conversations start from a more credible foundation

App developer

You publish on App Store and Google Play. With your LLC:

Apple pays US LLCs without additional withholding (W-8BEN-E properly configured with EIN)
Google Play similarly pays to your US account
Multiple apps managed under one LLC entity
Payments deposited monthly to your Mercury account

App Store and Google Play: collecting without headaches

Apple App Store

Apple pays to US bank accounts without additional withholding if W-8BEN-E is correctly configured with your EIN
Payments deposit monthly to your Mercury account
Manage multiple apps from the same developer account

Google Play

Similar to Apple: direct payments to your US bank account
No forced currency conversions
Complete dashboard for sales and metrics

Intellectual property protection

When you develop code, your LLC owns it. This means:

Clear IP ownership documentation
US copyright and trade secret protection applies. one of the most robust legal frameworks in the world
If you ever sell the business, the IP transfer is clean
Licensing arrangements can be structured through the LLC
If someone copies your code or violates your brand, the LLC files the legal action, not you personally

The complete developer/SaaS financial stack

At what scale does the LLC make sense?

Freelance developers: From $3,000+/month in revenue, the structure typically pays off.

SaaS businesses: Even at earlier stages. the operational benefits (Stripe access, platform integrations, professional entity) may justify it before the tax savings fully kick in.

The scaling toolkit: what to add at each stage

Scaling case study: from $3K to $30K/month

Month 1-3 ($3K/month): Solo freelancer, Mercury + Stripe. Billing 3 regular clients. Total annual revenue: ~$36K. Savings vs. autónomo: ~$6,000.

Month 4-8 ($8K/month): Added 2 large clients, hired first contractor (via Mercury wire). Added Wallester for subscriptions. Total annual run rate: ~$96K. Savings: ~$14,000.

Month 12-18 ($15K/month): Launched digital product. Added DoDo Payments for B2C sales. Relay for revenue stream separation (services vs. products). Total run rate: ~$180K. Savings: ~$28,000.

Month 24+ ($30K/month): Team of 4 contractors, multiple revenue streams. Slash for treasury management. Considering C-Corp conversion for potential VC funding. Total run rate: ~$360K. Structure has evolved from simple LLC to sophisticated business platform.

When to consider upgrading your structure

The LLC is perfect for most digital businesses, but at certain scales, you might evaluate alternatives:

At Exentax, we monitor your growth and proactively recommend structure changes when they make financial sense, not before.

Tax compliance in your country: CFC, controlled-foreign rules and income attribution

A US LLC is a fully legal, internationally recognized vehicle. But compliance does not end at incorporation: as an owner who is tax-resident elsewhere, your local tax authority still has the right to tax what the LLC earns. The key is under which regime.

By jurisdiction

Spain (LIRPF/LIS). An operative single-member disregarded LLC (real services, no significant passive income) is generally treated under income attribution (art. 87 LIRPF): the LLC's net profits are attributed to the member in the year they arise and integrated into the general IRPF base. If instead the LLC elects corporation treatment (Form 8832) and is controlled by a Spanish resident with mostly passive income, the CFC regime (art. 91 LIRPF for individuals, art. 100 LIS for companies) can apply. The choice is not optional: it depends on economic substance, not on the label.
Information returns. US bank accounts with average or year-end balance >€50,000: Form 720 (Law 5/2022 after CJEU C-788/19, 27/01/2022, penalties now under the general LGT regime). Related-party transactions and dividend repatriation: Form 232. US-custodied crypto: Form 721.
Spain–US tax treaty. The treaty (BOE 22/12/1990, Protocol in force 27/11/2019) governs double taxation on dividends, interest and royalties. An LLC without a permanent establishment in Spain does not by itself create a PE for the member, but effective management can if all activity is run from Spanish territory.
Mexico, Colombia, Argentina and other LATAM jurisdictions. Each has its own CFC regime (Mexico: Refipres; Argentina: foreign passive income; Chile: art. 41 G LIR). Common principle: profits retained inside the LLC are deemed received by the member if the entity is treated as transparent or controlled.

Before going further, put numbers on your case: the Exentax calculator compares, in under 2 minutes, your current tax bill with what you would carry running a US LLC properly declared in your country of residence.

> Find out whether an LLC fits your case

Practical rule: an operative LLC with substance, properly declared in your country of residence, is legitimate tax planning. An LLC used to hide income, fake non-residence or shift passive income with no economic justification falls within art. 15 LGT (anti-abuse) or, worse, art. 16 LGT (simulation). The facts decide, not the paperwork.

At Exentax we structure the entity to fit the first scenario and document every step so your local return can be defended in case of review.

LLC for developers and SaaS: the setup that professionalises your product from the first customer

If you build software, sell SaaS or develop for international clients, a US LLC solves three problems at once: you collect in USD/EUR without friction, professionalise your image with B2B corporate clients and lay the base to scale to a team or raise capital. Here is what works in real developers/SaaS.

Why the LLC fits SaaS and dev. Stripe US (best international payment experience), Mercury for B2B receivables, ability to list your SaaS on American marketplaces (AWS Marketplace, Salesforce AppExchange, Shopify) that require a US entity. Enterprise B2B clients sign with entities, not freelancers - the LLC opens that market.
Typical stack. Wyoming or Delaware LLC (Delaware if you plan to raise or convert to C-Corp), EIN, Mercury Business + Stripe US, Wise Business for EUR, GitHub/Vercel/AWS billed to the LLC (100% deductible), contractor agreements with developers W-9/W-8BEN. Maintenance: 1,500-2,500 USD annually.
If you plan to raise capital or sell the SaaS. Start directly with Delaware C-Corp (or LLC with clear conversion plan to C-Corp), not LLC in any state. VC investors and strategic buyers almost always require Delaware C-Corp for legal familiarity and preferred-share tax treatment. Changing later is possible but costly (5-15k legal fees).
Tax at residence. Spain resident: LLC profits taxed in IRPF as business activity. SaaS B2C EU: WATCH OUT for OSS (client-country VAT from 10k EUR/year). B2B international: clean invoice without VAT in most cases.

What we are asked the most

Wyoming or Delaware LLC for my SaaS? Bootstrapped SaaS without raise plan: Wyoming is cheaper and more private. SaaS with raise plan (angel, VC) or future C-Corp conversion: Delaware from day 1 saves expensive restructuring later.

Do my GitHub Sponsors / Stripe / paying users US go to the LLC from day 1? Yes, configure payout destination to the LLC's Mercury account and your Stripe to the LLC entity with its EIN. Migration: 1-2 hours of work, platforms keep history.

At Exentax we build the full developer/SaaS LLC stack (LLC + EIN + Mercury + Stripe + Wise + AWS/Vercel billing migration + monthly accounting) in 4-6 weeks, ready to invoice the first enterprise client.

Banking and tax facts worth clarifying

Fintech and CRS information evolves; here is the current state:

Notes by provider

Mercury operates with several federally chartered partner banks and FDIC coverage via sweep network: mainly Choice Financial Group and Evolve Bank & Trust, with Column N.A. still in some legacy accounts. Mercury is not itself a bank; it is a fintech platform backed by those partner banks. If Mercury closes an account, the balance is typically returned by paper check mailed to the account holder's registered address, which can be a serious operational problem for non-residents; keep a secondary account (Relay, Wise Business, etc.) as contingency.
Wise ships two clearly different products: Wise Personal and Wise Business. For an LLC you must open Wise Business, not the personal account. Important CRS nuance: a Wise Business held by a US LLC sits outside CRS because the account holder is a US entity and the US is not a CRS participant; the USD side operates via Wise US Inc. (FATCA perimeter, not CRS). In contrast, a Wise Personal opened by an individual tax-resident in Spain or another CRS jurisdiction does trigger CRS reporting via Wise Europe SA (Belgium) on that individual. Opening Wise for your LLC does not bring you into CRS through the LLC; a separate Wise Personal in your own name as a CRS-resident individual does report.
Wallester (Estonia) is a European financial entity with an EMI/issuing-bank licence. Its European IBAN accounts are within the Common Reporting Standard (CRS) and therefore trigger automatic reporting to the tax administration of the holder's country of residence.
Payoneer operates through European entities (Payoneer Europe Ltd, Ireland) that are also in scope for CRS for clients resident in participating jurisdictions.
Revolut Business: when paired with a US LLC, it operates under Revolut Technologies Inc. with Lead Bank as its US banking partner. The account delivered is a US account (routing + account number); no European IBAN is issued to a US LLC. The European IBANs (Lithuanian, Belgian) belong to Revolut Bank UAB and are issued to European clients of the group. If you are offered a European IBAN tied to your LLC, confirm exactly which legal entity holds that account and which regime it reports under.
Zero tax: no LLC structure delivers "zero tax" if you live in a country with CFC/tax transparency or income attribution rules. What you achieve is no double taxation and correct reporting at residence, not elimination.

On the same topic

What if HMRC, the IRS or my local tax authority asks about my LLC?

It's the question every client raises in the first consultation, and the short answer is: your LLC isn't opaque, and a properly declared structure closes any inquiry in standard forms. Your tax authority can request the state Certificate of Formation (Wyoming, Delaware or New Mexico), the EIN issued by the IRS, the signed Operating Agreement, the Mercury or Wise statements for the year, the Form 5472 plus pro-forma 1120 you filed, and the bookkeeping that reconciles income, expenses and movements. If all of that exists and is delivered in order, the inquiry doesn't escalate.

What tax authorities do pursue, and rightly, is sham ownership (nominees, paper residency) and undeclared foreign accounts. A well-structured LLC is the opposite: you appear as beneficial owner in the BOI Report when applicable (verifiable at fincen.gov/boi), you sign the bank accounts and you declare the income where you actually live. The structure is registered with the state Secretary of State, with the IRS and, when European banks are involved, inside the CRS perimeter of the OECD standard.

The mistake that really sinks an inquiry isn't having an LLC; it's not attributing the income correctly in your domestic return, not declaring foreign accounts when the year-end balance exceeds the local threshold (€50,000 in Spain via Modelo 720; the equivalent FBAR / Form 8938 in the US for residents; T1135 in Canada), and not documenting related-party transactions between the member and the LLC. Those three fronts are worth closing before any request arrives, not after.

## What an LLC does NOT do

- It does not exempt you from tax in your country of residence. If you live in Spain, France, Germany or Portugal, you are taxed there on worldwide income. The LLC organises your US side (zero federal tax for non-resident SMLLC pass-through, absent Effectively Connected Income); it does not switch off your domestic taxation. The income tax is computed on the attributed profit, not on the dividends actually paid.

- It is not an offshore vehicle or a BEPS scheme. It is a US entity recognised by the IRS, registered in a specific state with physical address, registered agent and annual informational filings. Classic offshore jurisdictions (BVI, Belize, Seychelles) leave no public trace; an LLC leaves a trace in five different places.

- It does not protect you if you commingle funds. The pierce the corporate veil doctrine kicks in as soon as a judge sees the LLC and the member behaving as the same wallet: mixed accounts, personal expenses paid from the LLC, no signed Operating Agreement, no bookkeeping. Three suspicious transactions are enough.

- It does not save you social security contributions at home. If you are self-employed in Spain, France or Germany, your monthly social contribution remains identical. The LLC handles the trading side with international clients; your personal contribution is independent.

- It does not exempt you from declaring foreign accounts. Spain residents file Modelo 720 / 721; UK residents, the SA106; Portugal residents, the Anexo J of Modelo 3 IRS; Germany residents, the Anlage AUS. Those obligations belong to the individual, not to the LLC.

At Exentax we cover those five fronts every year alongside the US federal calendar (Form 5472, pro-forma 1120, FBAR, state Annual Report and BOI Report when applicable). The goal is that no inquiry finds a loose end and that the structure withstands a 5-to-7-year retroactive review.
