Setting Up Payroll Giving in a Small UK Business: A Guide

Payroll giving is one of the more underused tools in a small employer’s benefits kit. It costs little, takes a couple of weeks to set up, and gives staff a tax-efficient way to support charities they actually care about — without the friction of Gift Aid forms or personal admin. For a business of fifteen, fifty, or two hundred people, it can be a quietly powerful piece of your culture and ESG story.

This guide walks through the practical steps of setting up payroll giving in a small UK business: who needs to be involved, which agency to pick, what your payroll team has to do, and the bits HMRC actually cares about.

What payroll giving is, briefly

Payroll giving (sometimes called Give As You Earn, or GAYE) lets employees donate to UK-registered charities directly from their gross salary. Because the deduction happens before income tax is calculated, the donor gets tax relief at their marginal rate immediately — a £10 donation costs a basic-rate taxpayer £8, and a higher-rate taxpayer £6.

Crucially, it’s not Gift Aid. Gift Aid recovers basic-rate tax for the charity after the fact; payroll giving avoids the tax being charged in the first place. For a fuller breakdown of the mechanics, see how payroll giving works.

The scheme is governed by Part 12 of the Income Tax (Earnings and Pensions) Act 2003 and administered through HMRC-approved intermediaries called Payroll Giving Agencies (PGAs).

Why bother as a small employer

Three reasons usually carry the day with a finance director:

1. Recruitment and retention. Younger staff in particular expect employers to make giving easy. A 2023 CAF UK Giving report found that under-35s are markedly more likely to want their employer to facilitate charitable activity than older cohorts.
2. Cost. There’s no employer NI saving (donations come out before income tax but after NI), but the actual cost to run a scheme is small — often under £20 a month in agency fees, sometimes nothing.
3. ESG reporting. If you’re starting to think about CSR for SMBs or building a social impact report, payroll giving generates clean, auditable numbers.

It’s also a sensible companion to other programmes — matched giving, a charity of the year partnership, or a volunteer time off policy. None of them require the others, but they reinforce each other.

Step 1: Confirm your payroll can handle it

Before you talk to anyone external, check that your payroll software supports payroll giving deductions. Almost all modern UK packages do — Sage, Xero Payroll, BrightPay, Moneysoft, IRIS, ADP, and so on — but the specifics vary.

What you’re looking for:

• A pre-tax deduction line distinct from pension or salary sacrifice
• The ability to label deductions clearly on payslips (employees should see “Payroll Giving” or similar)
• Reporting that lets you produce a monthly remittance file for the agency

If you outsource payroll to a bureau or accountant, send them an email now. They’ll either say “fine” or quote you a small one-off fee to configure it. Either is acceptable. What you don’t want is to discover at week three that your provider’s basic plan doesn’t support arbitrary deductions.

Step 2: Choose a Payroll Giving Agency

You cannot run payroll giving directly. By law, donations must pass through a PGA approved by HMRC. The agency receives the pooled deductions from your payroll, splits them according to employee instructions, and forwards them to the chosen charities.

As of 2024 there are a handful of approved PGAs in the UK. The main ones include:

Agency	Typical admin fee	Notes
Charities Trust	~£5/month employer fee or per-donor fee	Long-established; no minimum
Charitable Giving	Per-donor fee, often absorbed by employer	Not-for-profit; widely used
CAF Give As You Earn	Per-donor fee	Part of Charities Aid Foundation; well-known brand
Charities Aid Foundation (CAF)	Varies	Often paired with CAF accounts
Workplace Giving UK	Per-donor fee	Heavy focus on employer engagement

Fees are usually 25p–£2 per donor per month, sometimes with a minimum employer fee. Many employers absorb the fee on behalf of staff so the donation reaches the charity in full — a small but meaningful gesture. For more on the trade-offs see our comparison of payroll giving agencies.

Things to ask when shortlisting:

• Do you offer an online portal for employees to choose and change charities?
• How quickly do donations reach the charity (the legal maximum is 60 days from deduction)?
• Is there a minimum number of donors?
• Do you support one-off donations as well as recurring?
• What reporting do we get for our annual accounts and impact reporting?

For most small businesses the choice comes down to which agency your payroll provider integrates with most easily and whose portal your staff will actually use.

Step 3: Sign the contract and tell HMRC nothing

Once you pick a PGA, you sign their standard contract — usually a couple of pages. There is no HMRC registration step. You don’t need a dispensation, a unique scheme number, or any new reference. The PGA handles the regulatory side.

What does change is your payroll process. Going forward:

• Each pay run, you deduct the agreed amounts from participating employees before income tax (but after National Insurance and pension contributions)
• You transfer the total to the PGA, usually by BACS, within the timeframe in your contract (often by the 19th of the following month, mirroring PAYE deadlines)
• You send a remittance file showing who donated how much

Keep records for at least three years to satisfy HMRC’s general PAYE record-keeping requirements. The PGA keeps its own records too, but the employer is the legal payer.

Step 4: Decide whether to match

This is where small businesses can make the scheme genuinely interesting. Employer matching — where you add a top-up to whatever staff donate — turns a quiet payroll feature into something people talk about.

Common matching structures:

• £-for-£ up to a cap (e.g., match up to £30 per employee per month)
• Percentage match (e.g., 50% of all employee donations)
• Annual budget pool that’s split proportionally

A £50/month per employee cap across 30 staff is a maximum exposure of £18,000 a year, and actual take-up is rarely above 30–40% even in well-run schemes. In practice, a small employer’s matched giving spend tends to land at 20–40% of the theoretical ceiling.

For options and pitfalls see our deeper piece on designing a matched giving scheme.

Matching contributions are deductible against corporation tax as a charitable donation under Part 6 of the Corporation Tax Act 2010 — provided they go to a UK-registered charity. Keep the paper trail.

Step 5: Communicate it properly

This is where most schemes succeed or fail. You can have a perfectly configured payroll and a great PGA, and still end up with two donors out of forty because nobody knew about it.

A communication plan that actually works:

• Launch email from a senior leader, not HR. Explain why you’re doing it, not just how.
• All-hands or team-meeting slot (10 minutes) with a live demo of the PGA portal
• Written summary in the staff handbook or intranet — link to the PGA sign-up page directly
• Payslip note for the first month it’s available
• Anniversary nudge at six and twelve months

Don’t lean on the tax savings as the headline. Most employees find “support a cause you care about, straight from your pay, no hassle” more compelling than a percentage explanation. Save the maths for the FAQ.

Step 6: Run it, and report on it

Once you’re live, the operational load is small — but not zero. Each month your payroll team runs the deductions, sends the BACS payment and remittance to the PGA, and reconciles. The PGA distributes the funds and reports back.

Worth tracking quarterly:

• Number of active donors and participation rate
• Total donated (employee contributions + matching)
• Number of charities supported
• Average donation per donor

These figures feed into ESG and CSR reporting, year-end staff communications, and — increasingly — tender responses for public sector or large corporate contracts. If you’re working towards a B Corp certification or similar, payroll giving data sits neatly in the workers and community sections.

Common mistakes small businesses make

A few patterns we see repeatedly:

Treating it as a finance project. Payroll giving is half operational, half cultural. If only finance owns it, the comms layer collapses. Pair a finance lead with an HR or people lead from day one.

Picking the cheapest PGA without checking the employee portal. A clunky sign-up flow kills participation. Get a demo login from each shortlisted agency before signing.

Hiding the matching. If you match, say so. Loudly. The leverage of “every £1 you give becomes £2” is the single biggest driver of take-up.

Forgetting leavers. Build a tick into your offboarding checklist to stop deductions on the final payslip. Easy to miss, awkward to unwind.

Mixing it up with Gift Aid. Donations made via payroll giving cannot also have Gift Aid claimed on them — they’ve already had tax relief applied. Make this clear in your FAQs to avoid confusion. The differences are covered in payroll giving vs Gift Aid.

What it looks like at year one

A realistic outcome for a 50-person business after twelve months of a well-run scheme:

• 12–18 active donors (25–35% participation)
• £80–£150 average annual donation per donor
• £15,000–£25,000 total raised, including a 50% employer match
• Two to five hours of admin per month across payroll and HR
• One agency invoice line in the management accounts

That’s a meaningful charitable contribution, a tangible benefit on your careers page, and a genuine number to put in your impact report — for less effort than most expense policies.

Legal and compliance corners

A short checklist of things not to overlook:

• Employee consent. Donations are voluntary. Document each employee’s authorisation (the PGA portal handles this, but keep your own audit trail).
• Data protection. Charity choices are personal data. Your PGA’s privacy notice should be linked from any internal materials.
• Equality. Don’t structure matching in a way that effectively excludes part-time staff (e.g., flat caps work fine; eligibility tied to full-time status doesn’t).
• Contracts. No need to amend employment contracts. The Employment Rights Act 1996 permits payroll deductions where the employee has given prior written consent — which the PGA sign-up provides.
• Pension and salary sacrifice interaction. Payroll giving deductions come after salary sacrifice and pension. They reduce taxable pay but not pensionable pay. Check this with your pension provider if you operate a net pay arrangement.

When payroll giving isn’t the right starting point

Honestly, a few cases where you should pause:

• You have fewer than ten employees and no in-house payroll. The fixed setup overhead is disproportionate. Consider a community fundraising approach first.
• Your payroll is in the middle of migration. Wait until the dust settles.
• You have no leadership buy-in. A scheme launched purely by HR with no visible director endorsement rarely gets traction.

In those cases, employee volunteering or one-off fundraising events are easier first steps — payroll giving can follow once the appetite is proven.

The short version

Setting up payroll giving in a small UK business is mostly a paperwork exercise: pick a PGA, configure your payroll, sign the contract, communicate it well, and run it. There’s no HMRC registration, no minimum company size, and no statutory burden. The hard part is the cultural layer — making it visible enough that people actually use it.

Done well, it costs the business almost nothing and gives your team a low-friction way to support causes they care about, with HMRC quietly chipping in via the tax relief. For most SMBs that’s a remarkably good deal.

Questions HR keeps asking.

Is payroll giving worth it for a business with under 20 employees?+

Yes, provided your payroll software supports it and at least a handful of staff are interested. The administrative overhead is low — usually one extra deduction line per donor — and the tax relief is automatic. The main question is whether your chosen Payroll Giving Agency's monthly admin fee (typically £1–£2 per donor, sometimes waived) is something you or your employees will absorb.

Do we need HMRC's permission to set up payroll giving?+

No. You don't need to register with or notify HMRC to start a payroll giving scheme. You simply need to sign a contract with an HMRC-approved Payroll Giving Agency and configure your payroll software to deduct donations before tax. HMRC publishes the list of approved agencies but doesn't gatekeep the schemes themselves.

Can directors and company owners use the scheme too?+

Yes, as long as they are paid through PAYE. Sole traders and partners who draw profits rather than a salary cannot use payroll giving and should instead claim Gift Aid on personal donations.

What happens to an employee's donations if they leave?+

Deductions stop with their final payslip. Any donations already deducted are passed to the Payroll Giving Agency in the normal cycle and forwarded to the chosen charity. The employee can set up a new scheme with their next employer if they wish — donations don't transfer automatically.

Do we have to offer matched giving as well?+

No, matching is entirely optional. Many small businesses start with a straight payroll giving scheme and add matching later once participation is established. If you do match, you can cap it per employee or in total to control cost.

How long does it take to set up?+

Most small businesses can be live within two to four weeks. The Payroll Giving Agency contract takes a few days, payroll configuration is usually a single afternoon's work, and the rest is internal communication. The first deduction typically appears in the next full pay run after setup completes.
