Gift Aid is worth 25p for every £1 donated. For a charity receiving £200,000 in eligible donations per year, that is £50,000 in additional income from HMRC. Yet many charities leave money on the table because their systems do not track Gift Aid declarations properly, claims are submitted late, or eligible donations are missed entirely. This article covers what donor management actually involves, how Gift Aid claims work in practice, and what your software needs to do to handle both properly.
Donor management is often reduced to "a contact list with donation history." In practice, it is substantially more complex. A charity's relationship with each supporter involves multiple data points, and the software that manages those relationships needs to track all of them reliably.
Most off-the-shelf CRMs handle the first two or three of these well. The rest often requires workarounds, custom fields, or separate systems.
Gift Aid allows charities to claim an additional 25% on donations from UK taxpayers. The donor must have paid enough UK Income Tax or Capital Gains Tax in the relevant tax year to cover the amount being claimed. The charity must hold a valid Gift Aid declaration from the donor.
A valid Gift Aid declaration must include the donor's full name, home address, the name of the charity, and a statement that the donor wants the charity to treat the donation (and, optionally, future donations or past donations up to four years) as Gift Aid donations. The donor must confirm they are a UK taxpayer. Declarations can be made in writing, online, or verbally (if the charity keeps a contemporaneous record).
There are two routes for submitting Gift Aid claims to HMRC:
HMRC audits of Gift Aid claims reveal consistent patterns of errors. Each one costs the charity money, either through rejected claims or through eligible donations that were never claimed.
In February 2026, the UK's data protection framework was updated to include a "charitable soft opt-in" for donor communications. This brings charity fundraising communications closer in line with the rules that have long applied to commercial marketing.
Previously, charities needed explicit opt-in consent for all electronic fundraising communications (email, SMS). The new soft opt-in allows charities to contact existing supporters by email or SMS without prior consent, provided the supporter's details were obtained in the context of a donation or similar engagement, the charity gave the supporter a clear opportunity to opt out at the time, and the charity provides an opt-out mechanism in every subsequent communication.
Your CRM now needs to track not just whether a donor has opted in, but how their contact details were obtained and whether the soft opt-in conditions are met. This requires:
Most CRMs are updating to handle this, but the quality of implementation varies. Check that your system distinguishes between explicit consent and soft opt-in, and that it tracks the conditions under which each contact was added.
Donor management is not a static record-keeping exercise. It is the infrastructure that supports a journey from first contact to long-term partnership. Research consistently shows that digitally mature charities (those with integrated systems and data-driven engagement strategies) see 15 percentage points higher donor retention than those relying on manual processes and disconnected tools.
How donors first engage with the charity. Online donation forms, event registrations, crowdfunding campaigns, and peer-to-peer fundraising all generate new contacts. Your software needs to capture these reliably and attribute them to the right source.
Building the relationship from a first donation to regular giving. This requires segmentation (not every donor gets the same message), personalisation (acknowledging their specific history), and timing (asking at the right moment, not too often). Software that supports automated thank-you messages, targeted appeals based on giving history, and event invitations based on interest areas makes cultivation possible at scale.
Keeping existing donors is more cost-effective than acquiring new ones. Lapsed donor identification, renewal reminders for annual gifts, and regular impact reporting all contribute to retention. A CRM that flags donors who have not given in 12 months, or whose regular giving has stopped, allows fundraisers to intervene before the relationship is lost.
Legacy income (gifts left in wills) is the fastest-growing income stream for many UK charities. Legacies accounted for over £4 billion in charitable income in recent years, yet many charities track legacy intentions poorly or not at all.
What software needs to handle for legacy giving:
Most fundraising CRMs have some legacy tracking capability, but it is often an afterthought. The fields exist, but the workflows to support meaningful legacy stewardship are typically absent.
The challenges described above (Gift Aid tracking, GDPR compliance, donor journey management, legacy stewardship) are all solvable with off-the-shelf tools, but usually require compromises. Declarations are tracked in custom fields that do not integrate with the claim submission process. GDPR consent is recorded but the soft opt-in logic is not automated. Legacy pledges are noted but not stewarded systematically.
A bespoke system can be built to handle all of these as first-class features. Gift Aid declarations linked directly to HMRC submission via the Charities Online API. GDPR consent tracking with automated soft opt-in logic. A legacy pipeline with stewardship workflows and risk alerts. Donor journey stages that match the way your fundraising team actually works, not a generic template.
Whether this makes sense depends on the scale and complexity of your donor relationships. For a fuller analysis, see our charity software guide.
