1. The Problem with SaaS Tax Compliance
If you sell software to people in more than one country, you have a tax problem. It might not feel urgent today, but it's there — quietly accumulating obligations.
Here's what global SaaS tax compliance actually requires:
- Calculate the correct tax rate for every customer based on their location, your location, and whether they're a business or consumer
- Collect the tax at the point of sale — the right amount, with the right invoice wording
- File tax returns in every jurisdiction where you've collected tax (quarterly for EU VAT via OSS, monthly or quarterly for US states)
- Register for tax in each jurisdiction where you have an obligation — which can mean dozens of registrations if you sell worldwide
Most indie hackers and small SaaS founders ignore this until they hit a certain revenue level. That's understandable. But as you grow, you need a strategy. And there are really three paths forward:
- Do it yourself — use free tools, handle registration and filing manually
- Use a tax API — like Stripe Tax — to calculate and collect, then handle filing separately
- Use a Merchant of Record — like Paddle or LemonSqueezy — to offload everything
Each approach has real trade-offs in cost, control, and complexity. Let's dig into all three.
2. Quick Comparison Table
Before we go deep on each option, here's the side-by-side view. This table covers the differences that actually matter when you're choosing between them:
| Feature | Stripe Tax | Paddle | LemonSqueezy |
|---|---|---|---|
| Type | Tax calculation add-on | Merchant of Record | Merchant of Record |
| Pricing | 0.5% per transaction |
5% of revenue |
5% + 50¢ per txn |
| Tax calculation | Yes | Yes | Yes |
| Tax filing/remittance | No (you file) | Yes (they file) | Yes (they file) |
| VAT registration | No (you register) | Yes (they handle) | Yes (they handle) |
| US sales tax | Calculation only | Full compliance | Full compliance |
| EU VAT | Calculation only | Full compliance | Full compliance |
| Payment processing | Separate (Stripe) | Included | Included |
| Checkout | Your design | Paddle checkout | LemonSqueezy checkout |
| Revenue recognition | You own it | They own it | They own it |
| Best for | Control + scale | Hands-off compliance | Simplicity + indie hackers |
The fundamental split is between doing tax yourself with tools (Stripe Tax) and paying someone to do it all (Paddle, LemonSqueezy). Now let's unpack what each option actually means in practice.
3. Stripe Tax Deep Dive
What it does
Stripe Tax is an add-on to your existing Stripe integration. It automatically calculates the correct tax rate for every transaction based on your customer's location and your tax registrations. It adds the tax to the checkout, collects it as part of the payment, and gives you reports you can use for filing.
That's it. That's what you're paying for: calculation and collection.
What it doesn't do
Stripe Tax does not file tax returns on your behalf. It does not register you in any jurisdiction. It does not remit the collected tax to any government. Those responsibilities remain entirely yours.
This is the single most important thing to understand about Stripe Tax. Many founders assume "I turned on Stripe Tax, I'm compliant." You're not. You're collecting correctly, but you still need to:
- Register for VAT/sales tax in each jurisdiction where you have obligations
- File periodic returns (quarterly for EU VAT OSS, varies by US state)
- Remit the collected tax to the correct authorities
- Keep records and respond to any tax authority inquiries
Pricing
Stripe Tax costs 0.5% per transaction where tax is calculated. This is on top of Stripe's standard payment processing fees (typically 2.9% + 30¢). So your total Stripe cost on a taxed transaction is roughly 3.4% + 30¢.
Compare that to Paddle's flat 5% (which includes payment processing) and the math gets interesting depending on your average transaction size and volume. We'll break this down in the decision section.
Pros
- You keep full control over your revenue — it's your Stripe account, your customers, your data
- Works with your existing Stripe integration (minimal setup if you're already on Stripe)
- Lower total cost than MoR options for most SaaS businesses
- You design your own checkout experience
- Tax reports are clean and exportable
Cons
- Filing returns is still on you (or you need a filing service like Lovat, Taxually, or an accountant)
- Registration in each jurisdiction is still on you
- You need to understand where you need to register — Stripe Tax tells you where you might have obligations, but the decision and action is yours
- More moving parts to manage overall
4. Paddle Deep Dive
The Merchant of Record model
Paddle works fundamentally differently from Stripe Tax. When a customer buys your product through Paddle, they're not buying from you — they're buying from Paddle. Paddle is the Merchant of Record, which means legally, Paddle is the seller.
This has a massive implication: all tax obligations belong to Paddle, not to you. Paddle calculates the tax, collects it, files the returns, registers in every jurisdiction, and remits the money to the tax authorities. You receive a payout from Paddle minus their fee.
What's included
Paddle handles the complete tax lifecycle:
- Tax calculation — correct rates for every jurisdiction worldwide
- Tax collection — added at checkout automatically
- Tax registration — Paddle is registered everywhere they sell
- Tax filing and remittance — Paddle files and pays all tax obligations
- Invoicing — invoices are issued in Paddle's name (they're the legal seller)
- Chargebacks and refunds — Paddle handles these too
Pricing
Paddle charges 5% of revenue, which includes payment processing. There are no additional payment processing fees on top. For a $100 transaction, you pay $5 to Paddle. Period.
This makes the math simple, but it's worth noting: Stripe's payment processing alone is around 2.9% + 30¢. So Paddle's effective "tax compliance premium" over standard payment processing is roughly 2% — in exchange for handling everything.
Pros
- Completely hands-off tax compliance — genuinely zero tax work for you
- Covers all jurisdictions globally (EU VAT, US sales tax, UK VAT, and more)
- Handles chargebacks and refunds
- Single payout — you get one payment from Paddle, net of everything
- No need to understand tax rules at all (though it helps — see our EU VAT guide)
Cons
- Higher cost than Stripe Tax (5% vs ~3.4% total)
- Paddle legally owns the customer relationship — invoices come from Paddle, not from your brand
- Less flexibility with checkout design and payment flows
- Revenue recognition changes — your revenue is technically a "payout from Paddle," which can affect how investors and acquirers view your business
- Switching away from Paddle later requires migrating all customer payment methods
5. LemonSqueezy Deep Dive
What it is
LemonSqueezy is also a Merchant of Record, similar to Paddle. It was acquired by Stripe in 2023, which gives it an interesting position: it's an MoR built on top of Stripe's infrastructure, positioned specifically for indie hackers, solo founders, and creators.
The MoR model works the same as Paddle: LemonSqueezy is the legal seller, handles all tax compliance, and pays you out net of fees.
Pricing
LemonSqueezy charges 5% + 50¢ per transaction. That flat 50¢ fee is the key difference from Paddle. On a $100 transaction, you pay $5.50 (vs Paddle's $5.00). On a $10 transaction, you pay $1.00 — which is 10% of the transaction value.
This per-transaction flat fee makes LemonSqueezy relatively more expensive for low-value transactions. If your average sale is $20 or less, the 50¢ fee stacks up meaningfully.
Pros
- Simple, founder-friendly interface — the DX (developer experience) is genuinely good
- Full MoR compliance: calculation, collection, filing, registration — all handled
- Good checkout experience out of the box
- Built on Stripe's infrastructure (reliable payment processing)
- Strong positioning for digital products, courses, and SaaS — the audience they serve well
- Easy to get started — you can be up and selling in minutes
Cons
- Same MoR trade-offs as Paddle — they own the customer relationship legally
- The 50¢ per-transaction fee hits hard on small transactions
- Younger platform than Paddle — potentially fewer enterprise features
- Less flexibility for complex pricing models
- Being owned by Stripe creates an interesting strategic tension — will Stripe push you toward Stripe Tax instead over time?

There's no universally right answer. Your choice depends on your revenue level, your tolerance for admin work, and how much you value owning the customer relationship. Here's a practical decision framework:
Revenue under $10K/mo?
Consider the DIY approach with free tools. At this stage, 5% of revenue feels like a lot — it's money you could spend on growth. Use PayTaxFast's calculator to get rates right, generate compliant invoices, and handle filing yourself. Your tax obligations are likely limited to a few jurisdictions at this volume.
Revenue $10K-$50K/mo and you hate admin?
This is Paddle or LemonSqueezy territory. The 5% fee is real money ($500-$2,500/mo), but the peace of mind is worth it if tax compliance genuinely stresses you out or takes time away from building. Pick Paddle if you want the most established MoR. Pick LemonSqueezy if you value simplicity and a founder-friendly experience.
Revenue $50K+/mo?
This is where Stripe Tax + a filing service becomes the clear winner. At $50K/mo, you're paying $25,000/mo to Paddle (5%) versus roughly $1,700/mo to Stripe (0.5% Stripe Tax + ~2.9% payment processing). Even if you spend $500/mo on a filing service, you're saving over $22,000/mo. That's $264,000/year in savings.
B2B only?
DIY is probably fine. B2B sales in the EU use reverse charge, which means your customer handles the VAT. In the US, many B2B SaaS sales are exempt from sales tax depending on the state. Your compliance burden is dramatically lower than B2C.
At $20,000/mo: Paddle costs $1,000/mo. Stripe Tax costs ~$680/mo. Difference: $320/mo.
At $100,000/mo: Paddle costs $5,000/mo. Stripe Tax costs ~$3,400/mo. Difference: $1,600/mo. Add a $300/mo filing service and you're still saving $1,300/mo.
These numbers assume Stripe's standard 2.9% + 30¢ processing and Stripe Tax at 0.5%. Your actual rates may differ.
7. The DIY Option
Here's the thing nobody selling you a 5% tax solution wants you to hear: you don't have to use any of these services. Thousands of SaaS founders handle tax compliance themselves, especially in the early stages.
The DIY approach means you handle each piece of the compliance puzzle with the right tools:
- Calculate rates — Use the PayTaxFast calculator to determine the correct tax rate for any seller-buyer country combination. It covers EU VAT, US sales tax, and UK VAT.
- Generate compliant invoices — Use the PayTaxFast invoice generator to create invoices with the correct legal wording for every scenario (reverse charge, OSS, domestic, export).
- Check VAT numbers — Use the VAT registration checker to verify your B2B customers' VAT numbers before applying reverse charge.
- Know where to register — Use our VAT registration guide to understand your obligations.
- File returns — Quarterly for EU VAT (via OSS), and on each state's schedule for US sales tax.
The total cost? Free for the tools. You may need to pay for a registration agent (one-time cost per jurisdiction) and eventually a filing service as you scale. But you're looking at hundreds per year, not thousands per month.
When DIY makes sense
- You're early-stage and every dollar matters
- You sell to a small number of countries
- Most of your sales are B2B (reverse charge simplifies everything)
- You're comfortable with light administrative work
- You want to understand how tax compliance works before outsourcing it
When to upgrade from DIY
- You're spending more than a few hours per month on tax admin
- You're registered in so many jurisdictions that filing is becoming a burden
- You've made a tax error and it cost you money or time
- Your time is worth more than the cost of an MoR or filing service
8. FAQ
Is Stripe Tax enough for full compliance?
No. Stripe Tax handles tax calculation and collection, but you still need to file returns and register in each jurisdiction yourself. Think of Stripe Tax as doing half the job — the technical half. The administrative half (registration, filing, remittance) is still on you. Many founders pair Stripe Tax with a filing service to cover the full picture.
What's a Merchant of Record?
A Merchant of Record (MoR) is a company that legally sells your product on your behalf. When a customer buys through Paddle or LemonSqueezy, the customer's invoice comes from Paddle/LemonSqueezy — not from you. Because the MoR is the legal seller, all tax obligations (registration, calculation, collection, filing, remittance) belong to them. You receive payouts from the MoR, minus their fee.
Can I switch from Paddle to Stripe later?
Yes, but it takes work. You'll need to migrate your customers to new payment methods (they'll need to re-enter card details or set up new subscriptions), integrate Stripe's payment and tax APIs, set up your own tax registration and filing, and handle the transition of existing subscriptions. Many founders do this successfully as they scale. Plan for 2-4 weeks of migration effort, plus potential churn from customers who don't update their payment method.
Does LemonSqueezy handle US sales tax?
Yes. As a Merchant of Record, LemonSqueezy handles tax compliance in all jurisdictions they support, including US state sales tax, EU VAT, UK VAT, Canadian GST/HST, and more. Because they're the legal seller, all registration and filing obligations in those jurisdictions are theirs, not yours.
What's the cheapest option for tax compliance?
DIY with free tools like PayTaxFast. You can calculate rates, generate compliant invoices, and check VAT numbers at zero cost. Your only expenses are registration fees (varies by jurisdiction) and the time you spend filing returns. This approach works well for early-stage founders with sales in a handful of countries.
Do I still need to understand tax rules if I use Paddle?
Technically no — Paddle handles all the compliance. But practically, it helps to understand the basics. Knowing how EU VAT works helps you set prices intelligently (VAT-inclusive vs exclusive), understand why invoices look the way they do, plan for scenarios where you might outgrow an MoR, and have informed conversations with your accountant about your business structure.
