Company Off-Sites: Are You Getting the Tax Treatment Right?

For many employers, company off-site events are a regular part of the calendar. Typically held away from the workplace, these events bring employees together to hear business updates, discuss strategy and to take part in team-building activities.

They can also be a significant investment. Costs often include venue hire, travel, accommodation, meals and organised activities. But while the business benefits are usually clear, the tax implications are often less so.

Why Tax Treatment Matters

In most cases, these events are held for a genuine business purpose. Attendance is often compulsory, and much of the content may qualify as work-related training.

However, many events also include elements that go beyond training. This may include social activities, entertainment, or incentives. And this is where things become more complex.

From an employment tax and National Insurance (NIC) perspective, costs relating to the following can give rise to taxable benefits in kind:

  • staff entertainment
  • recreational activities
  • rewards or incentives

What About the £150 Annual Event Exemption?

Employers often assume that company off-sites fall within the £150 per head annual function exemption.

However, this exemption only applies where the event:

  • is open to all employees (or all employees at a location), and
  • qualifies as an annual function (such as a Christmas party or summer event)

Many off-sites do not meet these conditions. They may be limited to certain teams, structured as training events, or exceed the £150 per head limit once travel and accommodation are included.

Where the exemption does not apply, the usual benefit in kind rules must be considered.

HMRC is Watching

This isn’t just theoretical. HMRC is increasingly reviewing staff events as part of compliance checks.

Employers are often asked to provide:

  • a detailed cost breakdown
  • event agendas and itineraries
  • evidence of the business purpose

This is especially the case if the event is held somewhere HMRC views as an exotic or high-end location. With its guidance suggesting it may challenge trips to desirable locations that don’t clearly align with the business purpose.

Trips framed as an incentive or reward for performance are especially likely to be seen as taxable, as they often contain only a minimal business element.

What Not to Do: Avoid Treating Off-Sites as Perks or Rewards

To prevent the trip from being treated as a taxable benefit, it is essential that it is not presented as a social event, reward, or perk. Instead, you must be able to clearly demonstrate that:

  • the trip is primarily business-focused
  • the daily itinerary is largely composed of work-related activities
  • any social or leisure elements are strictly incidental

Robust documentation is critical. Agendas, schedules and supporting evidence of business content should be maintained to substantiate the purpose of the trip.

Certain team-building activities may qualify for exemption but only where they are appropriate and genuinely linked to work-related development.

Be aware that, even where there is a clear business purpose, elements such as evening drinks or purely recreational activities may still give rise to a taxable benefit.

Report Correctly

Where a taxable benefit arises, it must be reported to HMRC. The default treatment is to report any non-business element as a benefit in kind for the employee, on which they will be liable to income tax. The employer will also be liable to Class 1A National Insurance contributions on the value of the benefit.

Should you not wish your employees to foot the tax burden, you can consider using a PAYE Settlement Agreement (PSA).

A PAYE Settlement Agreement (PSA) allows the company to:

  • pay the income tax and NIC on behalf of employees
  • cover the cost of the benefit without employees being personally taxed

However, this comes at a cost:

  • The benefit must be grossed up, increasing the overall tax liability
  • The company bears the full financial burden

To use a PSA, you must apply to HMRC by 6 July following the end of the relevant tax year.

Plan Ahead

One of the most common pitfalls is addressing tax implications after the event has taken place.

Employers should consider potential tax and NIC costs, compliance obligations, documentation requirements at the planning stage, not as an afterthought.

Summary

Company off-site events can be valuable for morale and productivity, but they need to be structured carefully to avoid unexpected tax consequences.

If you’re planning a conference or overseas event, it’s worth considering if:

  • attendance was necessary for the employee to perform their job duties
  • the trip was predominantly work-related, not for entertainment

A bit of upfront planning can make the difference between a tax-efficient event and an expensive surprise.

FAQs

Do company off-sites always qualify for the £150 annual event exemption?

No. The £150 exemption only applies to events that are open to all employees (or all employees at a location) and qualify as an annual function, such as a Christmas party. Many staff off-sites don’t meet these criteria - particularly if they are team-specific, structured as training, or exceed the £150 per head limit when travel and accommodation are included.

When does a company off-site create a taxable benefit for employees?

A taxable benefit can arise where the event includes elements that are not wholly work-related. This typically includes entertainment, recreational activities, or incentive-style rewards. Even if there is a clear business purpose, any non-business elements may still be subject to income tax and National Insurance.

How can employers reduce the risk of unexpected tax charges on company off-sites?

Planning and documentation are key. Employers should ensure the event is primarily business-focused, with a clear agenda dominated by work-related activities. Keeping detailed records such as itineraries, cost breakdowns, and evidence of business purpose can help support the tax treatment if HMRC reviews the event.
