UK charities comparing Square and PayPal in 2026 need a different frame from the US comparison: Square Payments closed to new UK sellers in 2023, PayPal has a reduced rate for HMRC-recognised charities, and neither handles Gift Aid automatically.
In this article:
| Feature | Square | PayPal | Zeffy |
|---|---|---|---|
| Online transaction fee | 2.9% + £0.30 (Plus/Premium); 3.3% + £0.30 (Free tier) | 1.99% + £0.49 (registered 501(c)(3)); 2.89% + £0.49 standard | £0 |
| In-person transaction fee | 2.6% + £0.10 | Via PayPal's in-person card readers; standard processing rates apply | £0 with Tap to Pay on iPhone |
| Nonprofit discount | No standard nonprofit discount | Yes, for verified 501(c)(3) organizations | No discount needed; always free |
| Chargeback fee | £0 | £20 | £0 |
| HMRC-compliant tax receipts | No | No (transaction confirmation only) | Yes, automatic |
| Built-in donor CRM | No | No | Yes |
| Platform fee | £0 on Free tier; £29+/mo on Plus/Premium | £0 | £0 |
Choosing between Square and PayPal is a question many US nonprofits face. For UK charities, the honest answer in 2026 is that the comparison has changed significantly. Square wound down its Payments product for new UK sellers in April 2023. If you visit squareup.com/gb today, you will find that Square Payments is not open to new UK sign-ups. Existing UK sellers were given a wind-down window; most have moved on.
That changes the frame entirely. The practical question for a UK small charity is: PayPal vs. dedicated UK payment tools (SumUp, Zettle, GoodBox) vs. a free all-in-one platform like Zeffy.
This guide walks through the 2026 fee maths in £, what the UK alternatives actually look like, and the one gap the whole comparison hides: Gift Aid. Neither Square nor PayPal automates a Gift Aid declaration or files a claim to HMRC Charities Online. On a £30 donation from a UK taxpayer, that gap is worth £7.50 to your charity (HMRC Gift Aid guidance).
Fee maths gets abstract quickly. Here is what it looks like in pounds, using a £30 average gift and the current UK PayPal charity rate. For the canonical current rate, see the Zeffy vs. PayPal UK compare page (fees verified 2026-06-19).
Now layer in Gift Aid. For a £30 donation from a UK taxpayer, Gift Aid adds £7.50 to your charity at no cost to the donor. On £50,000 raised from Gift Aid-eligible donors using Zeffy (with Gift Aid automated), the Gift Aid top-up could add tens of thousands of pounds more over the year. Neither PayPal nor Square captures that for you automatically.
PayPal is a trusted checkout that many UK donors recognise. That familiarity reduces friction at the donate button, and that is a real advantage. For a small charity with a simple donate-page need, PayPal is straightforward to set up.
The honest limits are just as real, though. PayPal is a payment button, not a fundraising platform. It does not automate Gift Aid declarations. It does not offer ticketing, supporter management, auction tools, or a donor CRM. Most UK charities using PayPal end up paying separately for a supporter database (Beacon, Donorfy) and a ticketing tool (Ticket Tailor, TicketSource), and still processing Gift Aid claims manually.
To qualify for PayPal's reduced UK charity rate, your charity must be registered with the Charity Commission for England and Wales, OSCR (Scotland), or the Charity Commission for Northern Ireland, and must be HMRC-recognised. The application process is covered in the section below.

With Square Payments closed to new UK sellers, the real in-person toolkit for UK charities running fetes, quiz nights, and raffle stalls looks like this.
UK charities running community events consistently report that cash is dying. Supporters at summer fetes, church fairs, and village-hall quiz nights arrive without cash and expect to pay by card or phone. Per-ticket and per-transaction fees can price small charities out of affordable ticketing entirely.
Here are the UK options that actually work in 2026.
SumUp and Zettle (PayPal's in-person reader brand) are the dominant card readers at UK charity shops, fetes, and door collections. Both offer tap-to-pay card readers for under £30, no monthly fee, and sub-2% rates on most transactions. SumUp and Zettle both support tap-to-pay from a phone app, removing the need for separate hardware. For simple in-person payment needs at community events, either is a practical and affordable choice.
GoodBox makes purpose-built contactless donation devices (GBx) designed specifically for UK charities: churches, museums, visitor attractions, and street fundraising. The devices handle tap-to-donate directly on a physical unit, which can work well at unmanned giving points or high-footfall venues. See the Zeffy vs. GoodBox compare page for current UK fees (verified 2026-06-19).
Zeffy's Tap to Pay works on an iPhone with no card reader, no hardware purchase, and no per-tap fee. A volunteer with an iPhone can accept contactless cards and digital wallets at any event at £0 per transaction. For charities whose only reason to consider Square was the in-person micro-payment use case, Tap to Pay closes that gap at zero cost.
PayPal publishes a reduced rate for verified UK registered charities. Without that discount, your charity pays the standard PayPal business rate on every donation. Here is how the verification process works.
Before you apply: confirm that the current rate and application path are live at paypal.com/uk. PayPal updates its charity programme documentation periodically, and the fee structure can change.
Until that approval lands, every donation taken on PayPal is charged at the standard business rate. That is a real cost during the verification window, particularly if you launch a campaign before charity status is confirmed.
To compare Zeffy and PayPal side by side on UK fees, Gift Aid handling, and supporter management, visit the Zeffy vs. PayPal compare page. Zeffy's setup takes under 30 minutes for any registered UK charity, with no charity-programme application.
Fees are the headline, but charity-specific features decide whether the platform actually fits the work. Here is how PayPal and SumUp/Zettle (the realistic UK in-person alternatives) stack up on the four things that matter most for UK fundraising teams.
Neither PayPal nor SumUp/Zettle issues a Gift Aid declaration automatically or files a claim to HMRC Charities Online. They send transaction confirmations, which are not the same thing. Your charity is responsible for capturing Gift Aid declarations separately, processing them, and submitting claims manually or through a third-party tool. This is the largest single feature gap in any payment-only tool for UK charities. See the dedicated Gift Aid section below.
PayPal shows transaction histories; SumUp/Zettle show sales reporting. Neither maintains supporter profiles, segments giving history, or tracks lifetime value the way a fundraising CRM does. Most UK charities using these tools end up paying separately for Beacon or Donorfy (the two leading UK-built fundraising CRMs) to fill this gap.
Regular giving via Direct Debit accounts for around 31% of all UK charity donations, making it the single largest payment method in the sector. Neither PayPal nor SumUp/Zettle offers native Direct Debit. The standard UK route is GoCardless (1% + 20p per transaction, capped at £2; 25% charity discount available), which integrates into Beacon, Donorfy, and most UK fundraising platforms.
Both PayPal and SumUp export transaction data as CSV. Neither tags donations by campaign, fund, or grant restriction natively. If your funders require restricted-fund reporting or your charity needs to demonstrate compliance with the Code of Fundraising Practice (current version effective 1 November 2025), you will need to add that reporting layer yourself.
Gift Aid is the central UK charity-tax mechanism, and it has no equivalent in the US article this page is adapted from. Understanding it is the difference between a complete and an incomplete analysis of payment tools for UK charities.
Here is how it works. When a UK taxpayer donates and signs a Gift Aid declaration, HMRC returns 25p to your charity for every £1 donated, at no extra cost to the donor. A £30 donation becomes £37.50 to your charity. A £100 donation becomes £125. The donor pays nothing more; HMRC makes up the difference from the donor's paid income tax (HMRC Gift Aid guidance).
What neither PayPal nor SumUp/Zettle does:
If you use PayPal or SumUp as your payment tool, you must capture Gift Aid declarations separately (paper, a separate online form, or a bolted-on tool), keep records for at least six years, and submit claims manually to HMRC Charities Online. That is a real administrative burden that the percentage fee comparison does not capture.
Gift Aid Small Donations Scheme (GASDS) adds another layer. Charities can claim a 25% top-up on small cash and contactless donations of £30 or less, without a written declaration, up to £8,000 in eligible small donations per tax year. For a charity running summer fetes and quiz nights with contactless card readers, GASDS is material. Neither PayPal nor SumUp/Zettle helps you track or claim it.
Zeffy handles Gift Aid as part of the platform. Declarations are captured at the point of donation; your charity keeps a record for every eligible gift. The combination of £0 fees and Gift Aid automation is what closes the gap entirely for a typical UK charity.
The published fees are only part of the picture. A few things that do not appear in the standard comparison:
If the PayPal-vs-in-person-tools comparison leaves you with a tradeoff you do not want to make, here are the alternatives worth evaluating, ordered by fit for UK charity fundraising.
Zeffy is 100% free for UK charities, trusted by over 100,000 organisations that have collectively raised more than £2 billion through the platform. The only option in this comparison where your charity keeps 100% of every pound raised, at any donation size.
Stripe is the card-processing infrastructure that most UK fundraising platforms (including Zeffy) use under the hood. Its rate for UK cards is 1.5% + 20p per transaction, with a discounted rate available for verified charities processing a high proportion of donations. Like PayPal, Stripe is infrastructure, not a fundraising platform. UK charities using Stripe directly still need a donation form, Gift Aid tool, and supporter CRM on top.
GoCardless is the UK specialist for Direct Debit, the payment method behind approximately 31% of all UK charity donations. If regular giving is central to your fundraising strategy, GoCardless is the most important tool on this list.
CAF Donate is built by the Charities Aid Foundation, one of the UK's oldest charity infrastructure bodies. Used by over 8,000 UK charities for embedded donate buttons and Direct Debit giving.
Wonderful uses Open Banking (account-to-account transfer) to deliver genuinely 0% fees on donations. The donor authenticates via their banking app; the charity receives the full amount with no platform commission.
For in-person events, summer fetes, and raffle stalls, SumUp and Zettle are the dominant UK charity card readers. Both offer sub-2% rates, no monthly fee, and tap-to-pay from a phone app. Neither offers Gift Aid automation, donation forms, or a supporter CRM, but for simple in-person payment needs at community events, both are practical and affordable.
Zeffy is 100% free for UK charities, always. That is the line that closes the comparison. PayPal keeps a percentage of every online donation. SumUp and Zettle take a cut of every in-person tap. Zeffy keeps every pound in both columns.
SumUp and Zettle's strength is the card reader at the fete stall or charity shop door. Zeffy's answer is Tap to Pay on iPhone: no card reader, no hardware purchase. A volunteer with an iPhone can accept contactless cards and digital wallets at any event, and Zeffy charges £0 per tap. For charities whose only reason to use a card reader was the in-person event use case, Tap to Pay closes the gap without the percentage fee.
PayPal's strength is the trusted checkout that donors recognise. Zeffy's donation forms accept credit and debit cards, digital wallets, and direct bank transfer, with Gift Aid declarations captured automatically and a built-in supporter CRM. There is no charity-programme verification wait. Setup takes under 30 minutes.
Consider a village hall or community charity running a summer fete, an autumn appeal, a Christmas raffle, and a sponsored 5K. With conventional tools that means Ticket Tailor for ticketing, JustGiving or CAF Donate for the donate page, a separate tool for Gift Aid declarations, and Beacon or Donorfy for supporter management. Each tool has its own fee, subscription, or percentage. Zeffy consolidates all of that into one free platform, with Gift Aid handled, at £0.
That is the practical answer to the Square vs. PayPal question for a small UK charity in 2026.
Note: UK case studies for Zeffy are being gathered through our case-study programme. If your charity would like to share your story, get in touch.
Square wound down its Payments product for new UK sellers in April 2023. If you visit squareup.com/gb today, Square Payments is not open to new UK sign-ups. Existing UK sellers were given a wind-down window. For most UK charities looking at Square in 2026, the practical alternatives for in-person card payments are SumUp, Zettle, GoodBox, or Zeffy Tap to Pay on iPhone at £0 per transaction.
PayPal offers a reduced rate for verified UK registered charities. To qualify, your charity must be registered with the Charity Commission for England and Wales, OSCR (Scotland), or the Charity Commission for Northern Ireland, and must be HMRC-recognised for Gift Aid purposes. For the current verified UK charity rate, see the Zeffy vs. PayPal compare page (fees verified 2026-06-19 from PayPal UK's official pricing). Always confirm the live rate at paypal.com/uk before quoting it in donor communications, as PayPal updates its charity programme periodically.
No. Neither PayPal nor SumUp/Zettle captures a Gift Aid declaration at the point of donation or files a claim to HMRC Charities Online. If you use either as your payment tool, you must capture Gift Aid declarations separately, keep records for at least six years, and submit claims manually. On a £30 donation from a UK taxpayer, Gift Aid adds £7.50 to your charity. Zeffy captures Gift Aid declarations automatically as part of the donation form, so you never lose that uplift through an administrative gap. See HMRC's Gift Aid guidance for the full declaration requirements.
GASDS allows UK charities to claim a 25% top-up on small cash and contactless donations of £30 or less, without a written Gift Aid declaration, up to £8,000 in eligible small donations per tax year. For a charity running fetes, quiz nights, or church collections, GASDS is material. Your charity must be HMRC-recognised for at least two complete tax years to claim GASDS. See HMRC's Gift Aid guidance for full eligibility rules.
Yes. Zeffy is open to charitable organisations at all stages, including unincorporated associations, Community Interest Companies (CICs), and PTAs. Some features, such as automated Gift Aid, require HMRC recognition as a charity. If your group is not yet a registered charity, you can still use Zeffy's donation forms, ticketing, and in-person tools at £0. For guidance on the distinction between a registered charity and a community group or CIC, the Charity Commission and OSCR both publish clear guidance on their websites.
Zeffy is 100% free for charities: no platform fee, no transaction fee, no credit card fee. Zeffy is funded by optional voluntary contributions from donors at the point of giving. Donors are asked if they would like to support Zeffy; the contribution is completely optional. The charity always keeps 100% of every donation, regardless of whether the donor chooses to contribute to Zeffy.


UK charities relying on PayPal as their main donation platform lose money to fees and handle Gift Aid claims manually. This guide compares 8 PayPal alternatives for 2026, from Zeffy (0% fees, Gift Aid declarations built in) to CAF Donate, Wonderful.org, and GoCardless, with honest UK verdicts and fee calculations on a £20 gift.

Square is a popular card reader and payment platform, but it was built for businesses, not charities. This guide covers Square's UK fees, where it falls short for registered charities (especially around Gift Aid and small society lotteries), and how it compares to purpose-built UK charity fundraising platforms in 2026.


Every pound PayPal takes is a pound that does not reach your mission. This guide shows exactly what PayPal charges UK charities, what those fees cost in real programme pounds, and what your options are if you want to keep everything you raise.
