Employee Relocation Policy: A Practical Guide for HR and Global Mobility Teams

What an employee relocation policy actually covers

A relocation policy is a formal document that sets out the support, benefits, and procedures an organisation will provide when it relocates an employee. For HR and mobility teams, it serves three distinct functions: it defines what employees are entitled to, it gives finance a framework for budgeting, and it gives the business a defensible, consistent standard for managing exceptions.

Most corporate relocation policies address some combination of the following: eligibility criteria, the expense categories covered, tax treatment of benefits, payback obligations, and the process for accessing support. What separates a functional policy from a strategic one is how precisely it maps these elements to the different types of assignments your business actually uses.

The difference between domestic and international relocation policies

A domestic policy — relocating an employee from Manchester to London — is primarily a financial and HR exercise. An international policy adds immigration compliance, tax equalisation, duty of care obligations, currency risk, and, in many cases, the complexity of moving an entire family. The two require different frameworks. Organisations that try to apply a domestic template to international moves consistently run into gaps that create cost, legal risk, or assignee dissatisfaction.

Who the policy applies to — and who it doesn’t

Eligibility criteria matter more than most HR teams give them credit for. Policies typically differentiate by employment type (permanent vs. fixed-term), seniority, distance of move, and whether dependants are included. Getting this wrong in either direction creates problems: too narrow and the policy looks arbitrary to the employees it excludes; too broad and exceptions become the norm, which is expensive and hard to manage at scale.

Is relocation assistance taxable in the UK?

HMRC allows employers to reimburse up to £8,000 of qualifying relocation expenses without triggering a tax liability. Most standard moving costs fall within this threshold. Anything above £8,000 is treated as a taxable benefit.

The move needs to qualify — typically starting a new job or being required to work at a different location — and must meet HMRC’s conditions. If your employer is arranging relocation through a provider like Gerson, tax reporting is handled as part of the service. See our guide on tax implications for relocating employees.

The core components that a corporate relocation policy must address

Regardless of assignment type, a corporate relocation policy needs to address the following components consistently and clearly.

Eligibility criteria

Define who qualifies, under what circumstances, and from day one of employment or after a probationary period. Programmes that cover more than 25 moves per year typically apply stricter eligibility tiers — with different benefit levels for new hires versus existing employees, and for junior versus senior roles. The NEIRELO 2024 International All-Benefits Survey found that once a programme crosses the 25-move threshold, policy design and operational practice begin to diverge significantly.

Expense categories and cost caps

The policy should specify which costs the company will cover and to what limit. Standard categories for international moves include household goods shipping (air or sea freight), temporary accommodation (typically capped at 60–90 days), home-finding and orientation trips, immigration and visa fees, tax preparation and equalisation services, travel for the employee and eligible family members, school search and settling-in support.

An average international corporate relocation costs approximately $77,000 per employee — and can exceed $100,000 for senior hires when family relocation, temporary housing, and tax services are included (NRI Relocation, 2025). Setting realistic caps at the outset, by assignment tier, prevents budget overruns and creates a clear negotiation framework for exceptions.

UK tax treatment — the £8,000 exemption and what sits above it

For UK-based programmes, HMRC allows employers to cover up to £8,000 of qualifying relocation costs tax-free per employee. This threshold has been fixed since 1993, which means its real-world value has eroded considerably. Qualifying costs include home sale and purchase fees, removal costs, travel and temporary accommodation during the move, and costs of acquiring essential items for a new home.

Costs above £8,000, and any non-qualifying costs, become a taxable benefit-in-kind. This has two practical consequences for HR teams. First, the policy needs to define which costs are qualifying and which are not; second, any package designed around the £8,000 limit needs to account for the fact that international moves routinely exceed it. Tax equalisation provisions — where the employer covers the additional tax liability — are standard in most international mobility programmes and should be built into the policy from the start.

Payback and clawback clauses

Any policy that commits significant spend to a relocation should include a repayment provision covering the scenario where an employee leaves the business within a defined period after the move. Standard practice is a sliding scale: 100% repayable if the employee leaves within 12 months, reducing to 0% after two to three years. The policy should specify what triggers repayment (voluntary resignation, dismissal, mutual agreement) and how repayment is calculated — net of tax already paid is the most equitable approach.

Designing policy by assignment type

This is where most corporate relocation policies fall short. A single policy that tries to cover every assignment type ends up serving none of them well. The support requirements, cost structures, and compliance obligations for a six-month short-term assignment are fundamentally different from those of a permanent transfer. Getting this right requires building distinct policy tracks — or, at a minimum, clear annexes — for each major assignment type your business runs.

Long-term assignments

Typically 12 months to five years. The most complex assignment type in terms of policy design. Long-term assignees usually retain their home-country employment contract and compensation, which means tax equalisation, hypothetical tax calculations, and ongoing cost-of-living adjustments are necessary. The policy needs to address housing in both the home and host country, schooling for dependent children, partner support, and the repatriation process at assignment end. Repatriation gets underplanned more often than any other phase of the assignment — assignees who return without a clear role or reintegration process represent a significant retention risk.

Short-term assignments

Three to twelve months. Typically driven by project work or knowledge transfer. The assignee usually remains on home-country payroll, which simplifies tax but doesn’t eliminate immigration requirements — business visitor visa limits vary significantly by country and are frequently miscalculated. Short-term assignment policies typically cover temporary furnished accommodation, return flights, and a daily allowance, rather than full household goods shipment or school search support.

Permanent transfers

The employee moves permanently to the host country and transitions onto local payroll and benefits. The relocation package is typically more generous at the point of move — household goods, home sale/purchase support, settling-in services — but ongoing assignment allowances do not apply. The tax treatment is often simpler than long-term assignments, but immigration work is typically more complex, as the employee needs permanent residency status rather than an assignment visa.

Lump sum relocations

A defined cash payment given to the employee to self-manage their move. Popular for junior hires and domestic relocations. The managed lump sum — where the employee receives the payment but works with a relocation provider who guides their choices — addresses the most common failure mode: employees spending on non-relocation priorities, underinvesting in settling-in support, or missing immigration requirements entirely. For international moves, a pure lump sum without provider support creates material duty of care and compliance risks.

The core-flex model — what it is and when it fits

Core-flex is the policy design approach that most large global mobility programmes are moving toward. Rather than a single, uniform package by assignment tier, it defines a set of core benefits that every assignee at that level receives (e.g., visa support, household goods shipment, temporary accommodation), alongside a menu of flexible benefits from which the assignee can choose based on their circumstances (e.g., school search, partner support, cultural training, additional home visits).

The appeal for HR and finance is twofold: it creates consistency at the core, which is defensible from an equity standpoint, while reducing the volume of one-off exceptions, which are typically the biggest source of cost overrun. One in three global mobility leaders surveyed by KPMG in 2025 cited articulating a clear, flexible policy strategy as a top priority — and core-flex design is a central component of that shift.

International policy considerations — what changes when employees cross borders

Moving an employee to another country introduces obligations that a domestic policy simply doesn’t need to address. HR teams managing their first international programme often underestimate the compliance surface area.

Immigration and right-to-work obligations

Every international move requires an immigration pathway that’s confirmed before the employee travels — not applied for after arrival. The type of visa, the processing timeline, and the employer’s sponsorship obligations vary substantially by destination country. Getting this wrong doesn’t just delay a move; it can invalidate an assignment entirely, create personal liability for the employee, and in some jurisdictions, expose the company to fines.

The relocation policy should define who owns immigration coordination (typically the mobility team or an external immigration partner), what documentation the employee must provide, and the minimum notice period required before a planned start date. Build in realistic lead times: UK Global Business Mobility visa applications, for instance, currently carry processing times that can run to several weeks, even with premium service.

Tax equalisation and assignment cost planning

Tax equalisation ensures that an internationally mobile employee pays no more — and no less — in personal income tax than they would have paid if they had remained at home. The employer makes up any shortfall and retains any tax savings, which provides cost predictability. Without it, assignees to high-tax destinations face a significant personal financial penalty, and assignees to low-tax destinations receive an unintended windfall. Both outcomes create fairness issues that feed through into assignee satisfaction and retention.

Tax equalisation calculations involve the home-country tax rate, the host-country tax rate, and a hypothetical tax figure that the employee is deemed to pay. This requires specialist input — either an internal global mobility tax team or an external adviser. The policy should specify which costs are covered by equalisation, how the annual settlement is calculated, and what happens at assignment end.

Duty of care for internationally mobile employees

Duty of care has moved from a compliance footnote to a central pillar of global mobility strategy. Employers have a legal and ethical obligation to protect the health, security, and wellbeing of employees assigned abroad — and increasingly, their families. The obligation extends beyond adequate health insurance to include: security risk assessment for the destination, access to 24/7 medical and security support, mental health provisions, and clear protocols for emergency repatriation.

The consequences of under-investing here are well-documented. From Gerson Relocation’s experience managing corporate moves across more than 180 countries, the assignments most likely to run into crisis are often those where duty of care was treated as a box-ticking exercise rather than a live operational responsibility. The policy should define exactly what duty of care support is provided, by whom, and how the employee accesses it from day one.

Lump sum vs. managed relocation — choosing the right policy model

The decision between a lump sum and a managed relocation programme is one of the most consequential choices in policy design, and it’s rarely straightforward.

A lump sum gives the employee a defined cash amount to manage their own move. The appeal is simplicity and cost predictability — the company pays a fixed sum, and the administrative burden shifts to the employee. The WHR Global Mobility Benchmark Report found that 55% of relocation programmes offer a lump sum option for new hires, with an average lump sum payment of $14,608.

The risks are real. Employees spending a lump sum without guidance frequently make less effective decisions — choosing cheaper accommodation that isn’t close to the workplace, skipping cultural training, or failing to use specialist immigration support. For international moves specifically, fewer than 11% of organisations use lump sum-only policies for permanent moves, reflecting the recognition that the complexity of cross-border relocations typically requires managed support.

The managed approach — where the company works with a relocation management company to coordinate services — costs more upfront but tends to deliver better outcomes. Assignees arrive better prepared, settle faster, and are less likely to cut an assignment short. Given that a failed international assignment can cost up to $1.25 million, the economics of proper support are straightforward.

The managed lump sum sits between the two: the employee receives a defined budget but works with a relocation provider who assesses their needs and guides them through the process. This model combines cost predictability with professional support — and is increasingly the default for mid-tier assignments at organisations managing programmes of any meaningful scale.

How to benchmark your relocation policy against the market

A relocation policy that was competitive three years ago may no longer be. The 2025 KPMG Global Mobility Benchmarking Report found that 42% of organisations completed a comprehensive policy review in the past year, with external benchmarking of competitiveness cited as a top driver by 55% of respondents.

Benchmarking should answer three questions: Are the benefit levels in line with what comparable organisations are offering? Are the assignment types we support reflected in how the market is moving? And are there areas where we’re overspending relative to the outcomes we’re getting?

For most organisations, benchmarking is a combination of peer data (often accessed through industry surveys from Mercer, KPMG, or AIRINC) and specialist advisory input. Gerson works with an independent panel of Global Mobility advisors — former in-house GM heads, reward specialists, and tax practitioners — who can run a benchmarking exercise against specific sectors and geographies. The output is a clear view of where a policy is competitive, where it’s out of step, and what adjustments would bring the most meaningful improvement.

When to review your relocation policy

Most organisations review their relocation policy when something goes wrong — an assignment fails, a cost overrun occurs, or an assignee complains. That’s reactive. The organisations with the most efficient programmes treat policy review as a scheduled activity, not a firefighting response.

Common triggers that should prompt a review:

• Change in business strategy — entering a new geography, opening a new office, or restructuring into regional hubs all change the relocation profile of the organisation
• M&A activity — inherited policies from acquired entities need to be assessed and consolidated
• Significant change in assignment volume — a programme that crosses the 25-move threshold needs a different level of operational rigour and policy specificity
• Tax or immigration law changes — host-country rule changes can make previously standard provisions non-compliant overnight
• Sustained exception rate above 15% — if more than one in seven moves is generating an exception request, the policy isn’t fit for purpose
• Scheduled benchmarking — the market moves; an annual or biennial review against peer data is standard in well-run programmes

Working with a relocation management partner on policy

Relocation policy design doesn’t have to happen in isolation. A good relocation management company brings three things that are hard to replicate internally: volume data on what comparable organisations are spending and how they’re structuring benefits; operational intelligence on what provisions actually drive assignee satisfaction; and specialist expertise across immigration, tax, and logistics that most in-house teams can’t maintain across every destination market.

When evaluating a relocation partner, the questions that matter for HR and procurement aren’t primarily about price. They’re about operational capability: Does the partner deliver the physical move itself, or do they subcontract it? Who is accountable when something goes wrong? What does their technology platform provide in terms of data, reporting, and assignee self-service?

Gerson is one of a small number of relocation management companies that handles the physical household move directly, rather than subcontracting it to a third party.
