Over a Quarter of UK Employees Admit to Using AI to Generate or Manipulate Expense Receipts to Top Up Their Salary

New research from Emburse highlights growing financial strain on employees is leading to fraudulent expense claims

LONDON--(BUSINESS WIRE)--Over one-quarter of UK employees (29%) have admitted to using AI to generate or manipulate expense receipts to top up their salary. An even higher number (40%) have also admitted they have either submitted personal purchases as business expenses or considered doing so because of concerns about their own personal finances.

The findings, based on a survey of 1,000 working professionals across the UK, conducted by the global leader in AI-powered travel and expense management Emburse, point to mounting financial strain on employees and a growing fraud risk for employers as AI tools become more accessible.

The study also reveals growing concern among employees who are routinely required to cover business expenses out of their own pockets. More than two-thirds (68%) of UK office workers say they have incurred bank fees after paying for business expenses out of their own pocket after being forced to use their own personal debit or credit cards.

Set against ongoing cost-of-living pressures, many workers report feeling financially stretched, with delayed repayments and upfront spending adding further strain to their personal finances.

The research also found:

• Three-fifths (61%) wait more than a week to be reimbursed.
• Half (51%) say delayed reimbursements have caused them financial strain.
• Nearly three-quarters (73%) said they would prefer to use a company credit card for business expenses.

Marne Martin, CEO of Emburse, said:

“As the cost-of-living crisis has progressively worsened, the expectation that employees must absorb additional charges, interest, or overdraft fees linked to work-related spending is unsustainable. The research reveals a painful truth: when companies require staff to cover business expenses upfront, the arrangement can effectively amount to an interest-free loan from employee to employer. For workers already navigating rising living costs, this temporary loss of funds can impact cash flow, increase reliance on credit, and, in some cases, lead to overdraft or interest charges. Far too many employees are effectively subsidising business spending themselves, paying for work costs on personal cards and waiting to be paid back. They are effectively being forced to act as short-term lenders to their employer. Businesses instead have an opportunity to rethink outdated processes and put systems in place that are faster and more transparent, for a better employee experience.”
