Long-distance assignment allowances: rates and exemption

Quick answer. A long-distance assignment covers an employee who cannot return home each evening, a situation presumed once the assignment site is at least 50 km from their residence and the public-transport journey exceeds 1h30. Flat-rate meal and lodging allowances are then exempt from social contributions and income tax within the URSSAF rates, with tapering from the 4th month.

An employee sent for several weeks to a site across the region, a technician staying in a hotel during a long assignment, a sales representative spending night after night away from home: each time, the employer pays allowances to cover meals and accommodation. These amounts can be exempt from social contributions and income tax, but under precise conditions and within fixed limits. Confusing a long-distance assignment with a simple meal expense, exceeding the rate unknowingly, or forgetting the tapering of long assignments leads to costly URSSAF adjustments.

This analysis is aimed at managers, HR officers and payroll specialists who want to secure the treatment of flat-rate long-distance assignment allowances. At Hayot Expertise, we regularly support employers in construction, technical installation and itinerant consulting on this topic, where a single method error repeats on every payslip and for every affected employee.

A long-distance assignment is defined by the impossibility, for the employee, of returning to their residence at the end of each working day. URSSAF presumes this impossibility when two conditions are met at the same time: the distance between the place of residence and the place of work is at least 50 km one way, and that journey cannot be made by public transport in under 1h30.

These two criteria are cumulative. A 60 km trip reachable in one hour by train does not trigger the presumption; likewise, a 1h45 public-transport journey over only 30 km does not either. When the criteria are not met, the employer can still justify the impossibility of returning home through other objective factors (assignment hours, lack of suitable transport), but loses the comfort of the presumption.

The long-distance assignment differs from the short-distance trip, which covers expenses incurred within the employee's usual work area, for example a meal taken during an assignment near the company. The regime, the rates and the exemption logic are not the same.

Long-distance versus short-distance: the sorting table#

This first qualification step is decisive: applying the long-distance rate to a situation that does not warrant it exposes the employer to an adjustment, and vice versa.

Flat-rate long-distance assignment allowances are exempt from social contributions and income tax within the limits of the flat-rate scales set by URSSAF. These scales cover two distinct items: the meal, assessed per meal, and lodging with breakfast, assessed per night.

The scale has a geographic feature: the amount for lodging with breakfast is higher for Paris and its inner ring (departments 75, 92, 93 and 94) than for other departments, to reflect accommodation costs. The meal item follows a single amount.

The reference amounts change each year. According to the 2026 URSSAF scale (amounts re-assessed each year, to be confirmed on urssaf.fr before use), the orders of magnitude are as follows: around 20.70 euros per meal; around 74.30 euros per night for lodging and breakfast in Paris and the inner ring; around 55.10 euros per night for other departments. We stress this: these values must be checked against the scale in force before any payroll calculation, as they are revalued at the start of each year.

Summary table of the scale and tapering#

Where the allowance paid exceeds the exempt ceiling, the excess fraction is reinstated in the contribution base, unless the employer can justify higher actual expenses with supporting documents. To understand how this fraction is added to the URSSAF contribution base, the ceiling-by-bracket mechanism is worth mastering in parallel.

The exemption regime is not fixed over time. When the employee remains continuously assigned to the same place of work, URSSAF considers that their setup costs decrease and applies a tapering of the exempt amounts.

The mechanism is as follows: a 15 % reduction applies to the exempt amounts from the 4th month and up to the 24th month of continuous presence at the same site; then a 30 % reduction applies from the 25th month, that is beyond 24 months. This tapering progressively reduces the share of allowance the employer can pay free of contributions for prolonged stays.

The underestimated risk here is tangible: many employers keep applying the full scale to sites or assignments lasting more than three months, without triggering the reduction. The fraction that should have been reinstated piles up month after month and employee after employee, until it represents a significant adjustment base in the event of an audit.

The payroll treatment follows a flat-rate allowance logic: as long as the allowance stays within the scale, it is exempt and bears neither contributions nor tax. The part exceeding the scale is reinstated in the base, like additional pay, unless actual-expense documents cover the overrun.

A structuring point: flat-rate allowances do not combine with reimbursement of the same expenses at actual cost. The employer chooses one coverage method per expense type. Paying an exempt meal flat rate while also reimbursing restaurant receipts for the same meal is not allowed and weakens the whole arrangement.

1. Check the long-distance conditions. Confirm that the 50 km and 1h30 criteria are met, or gather the objective elements justifying the impossibility of returning home.
2. Separate meals and lodging. Identify the number of meals and nights actually concerned by the assignment, without applying a flat rate beyond the need.
3. Apply the scale in force. Use the URSSAF amounts for the current year, taking into account the Paris and inner ring / other departments distinction.
4. Trigger the duration reduction. Calculate the switch date at 4 months (15 % reduction) then at 25 months (30 % reduction) for each employee remaining at the same site.
5. Keep supporting documents. Document the assignment (assignment order, location, duration, distance) to support the exemption in case of audit.
6. Report in payroll and DSN. Record the exempt allowances and, where applicable, the reinstated fraction, with the correct contribution code, and check consistency on the payslip given to the employee.

Our payroll and professional-expense teams configure these rules directly in the software so the scale and tapering apply automatically, without manual recalculation on each payslip.

An employee housed free of charge by the employer, or whose accommodation is covered directly, cannot also receive the flat-rate lodging allowance: that would cover the same expense twice. The non-combination logic applies item by item.

Employees on long-distance assignment abroad follow specific rules and distinct scales, which should be examined separately. Likewise, some collective agreements provide for contractual travel allowances: their social treatment combines with the URSSAF scale, which can raise multi-agreement and multi-establishment payroll questions when the company applies several texts.

The first point of attention concerns the confusion between long-distance allowance and benefit in kind. When the employer directly provides the meal or lodging, the situation shifts to the logic of nourriture and lodging benefits in kind, assessed under other rules. Failing to distinguish the two regimes distorts the contribution base.

The second point concerns the annual revaluation of amounts. The long-distance scale is revalued each year by URSSAF. Payroll settings frozen on last year's values mechanically exempt too much or too little. This consistency check is best built into the move to the 2026 payslip.

The third point is traceability. What the authorities look at first is the reality of the assignment situation: an assignment order, the actual duration, the distance, the absence of double reimbursement. An undocumented exemption is a fragile exemption.

Recently, a construction employer approached us after a first URSSAF audit on long-distance assignment allowances. Several employees had been working for more than eight months at the same site, and the company was paying the full lodging flat rate, without the duration reduction. The fraction that should have been reinstated from the 4th month had accumulated over several years and several employees, turning a simple settings oversight into a substantial adjustment base.

Our reading is this: on this topic, the risk almost never comes from fraud, but from a payroll automation that fails to integrate the two key variables, the geographic ceiling and tapering over time. An employer with a single occasional assignment rarely gets it wrong; one managing long, repeated assignments does. Securing it therefore depends less on knowing an exact amount than on rigorous settings and an annual review, a task we build into our payroll engagement. For broader monitoring of mobility costs, an outsourced CFO for SMEs can also objectify the trade-off between flat rate and actual expenses.

As a chartered accountant registered with the French professional Order, we recall that this article informs on a general framework: qualifying a long-distance assignment and calculating the exact exemption must be assessed in light of the employee's real situation, the applicable agreement and the scale in force.

Hayot Expertise tip. Before each payroll campaign, check the year's long-distance scale on urssaf.fr and compare it with your settings. For each employee on a long assignment, record the site start date, so the 15 % then 30 % reductions are triggered at the right time. Document every assignment.
