Polar vs Stripe: Which Payment Setup Fits Your Software Business in 2026?
Polar is a merchant of record that handles sales tax and VAT for you; Stripe is a payment processor with a lower rate and the tax work left with you. Here is what each costs at your sales volume.
By Bill Belcamino · Last updated September 27, 2026 · Our methodologyResearched and fact-checked by the HelpCompare team
Starter: no monthly fee, 5% + 50¢ per transaction; Pro $20/mo at 3.8% + 40¢
Bottom line up front: Is Polar's higher rate worth it to get out of doing sales tax, or should a software seller stay on Stripe?
It comes down to one question: how many places would you have to register and file tax if you were the seller?
Stripe is 2.9% + 30¢ with no monthly fee, while Polar runs from 5% + 50¢ on Starter down to 3.4% + 30¢ on Scale at $400/mo, and that premium buys Polar taking on the liability for US sales tax, EU VAT and Canadian GST. Stripe Tax at 0.5% doesn't close the gap, because it only calculates and collects where you're registered, and the filing stays yours. Tax exposure follows your customers, not your office, and selling digital products to consumers abroad can create obligations long before your revenue feels big. I spent 13 years building web properties with my own money, so here's the number I'd get before comparing rates: pull last year's sales by country and US state and have your accountant say where you'd need to register. A short list means take Stripe's rate; a long one means Polar's premium is cheaper than running your own filing calendar.

Is Polar cheaper than Stripe?
Stripe, on fees. At $10,000 a month in $25 sales, Stripe’s 2.9% + 30¢ comes to $410; Polar Pro comes to $560 including its $20 plan fee, and Polar Starter to $700. Add Stripe Billing (0.7%) and Stripe Tax (0.5%) to run subscriptions with tax calculated and Stripe comes to $530, close to Polar Pro, but filing and remitting the tax is still yours. Both add 1.5% for international cards and charge $15 per dispute.

Fees in USD from polar.sh/resources/pricing, Polar’s fees documentation and stripe.com/pricing, all checked September 27, 2026. Polar is a merchant of record: it sells to your customer as the reseller and takes on the liability for sales tax, VAT and GST. Stripe is a payment processor: you are the seller, so registering, collecting and remitting tax stays your job (Stripe Tax, at 0.5% per transaction, calculates and collects where you are registered).
These are not two versions of the same product. Stripe moves the money and leaves the legal seller role with you. Polar sits in front as the seller of record, which is why its rate is higher.
Who owes the sales tax
Polar is a merchant of record: it sells to your customer as the reseller and takes on the liability for sales tax, VAT and GST. Stripe is a payment processor: you are the seller, so registering, collecting and remitting tax stays your job (Stripe Tax, at 0.5% per transaction, calculates and collects where you are registered). Polar still notes that your own income tax at home is yours. Stripe also offers Managed Payments, its own merchant of record option, at 3.5% per transaction on top of its payment fees.
Polar’s plans are a volume bet
Polar’s monthly plans trade a fixed fee for a lower rate: $20 a month cuts Starter’s 5% + 50¢ to 3.8% + 40¢, $100 gets 3.6% + 35¢ and $400 gets 3.4% + 30¢. The more you sell, the higher the plan that pays for itself. Small average sales make the fixed per-sale fee matter most: 50¢ on a $25 sale is another 2%.
The fees people forget
Both charge 1.5% more on international cards and $15 per dispute. Polar passes through Stripe’s payout fees ($2 a month for active payouts plus 0.25% + 25¢ per payout) and does not return transaction fees on refunds. Stripe charges 1% when currency conversion is needed. The calculator folds each fixed per-sale fee into the rate at the average sale size in the plan name, and adds Polar’s monthly plan fee. It leaves out the 1.5% both charge on international cards, $15 disputes, currency conversion and Polar’s payout fees ($2 a month for active payouts plus 0.25% + 25¢ per payout).
Moving between them
Polar has a self-serve Stripe importer that copies products, customers, selected subscriptions and saved cards, with the card copy started by the Stripe account owner. Leaving Polar, its team transfers customers and saved cards to your new processor, but products, prices, discounts and active subscriptions have to be recreated.

Ready to pick your payment setup?
Price the tax work before you price the fees. If you would need to register for VAT or sales tax in several places, compare Polar’s rate against Stripe plus that work; if not, Stripe’s rate is hard to beat.

Audit reports: Stripe states a SOC 2 report on its own site; we found no SOC 2 statement for Polar. If your security team requires SOC 2, ask Polar directly before shortlisting.
Single sign-on: Stripe includes it. Polar doesn’t document single sign-on with your own identity provider. If your team signs in through Okta, Microsoft Entra ID or Google, price the plan that includes SSO, not the entry plan.
Working offline: Stripe works offline only in part; Polar doesn’t document an offline mode. Details are in the Offline mode row above.
In the office: Stripe: Stripe Terminal supports pre-certified card readers (Stripe Reader S700/S710, BBPOS WisePOS E, Stripe Reader M2, BBPOS WisePad 3, Verifone) and Tap to Pay.
