The four questions behind every posting
A posting is a temporary assignment of an employee to work in another country while the employment relationship continues with the Israeli company. The details differ between a three-week project and a three-year assignment, but the questions are the same: tax, social security, permission to work, and the company's own exposure.
Starting too late is the main mistake. A manager who tells HR on Friday that an engineer leaves on Monday has already created problems that take months to correct, from missing work permits to a salary taxed in two countries.
Create a short checklist and require it for every assignment longer than a few days. The checklist should be completed by HR, finance and the line manager before the flight is booked.
Contractors sent abroad are a variant: a freelancer working for you in another country carries the same permit and tax questions, plus the risk that the relationship is reclassified as employment.
Income tax and residency
An employee's tax position depends on residency and on the rules of both countries, including any tax treaty between them. Short assignments often leave residency unchanged, while long ones may change it, which affects which country taxes the salary and how foreign tax is credited.
The employer's withholding duties continue in Israel for an Israeli resident employee, and the host country may impose its own withholding or reporting obligations from the first day or after a threshold of days.
Ask your accountant to model the net pay of the employee in both scenarios. People accept assignments based on the net amount, and a surprise tax bill abroad quickly damages trust.
Ask also about equalisation: if the host country is more expensive or taxes more heavily, the company may agree to top up the pay, and that promise belongs in the assignment letter.
Social security: Bituach Leumi and the host country
Israel has social security agreements with a number of countries that can keep an employee insured in one system during a posting and avoid paying twice. Whether an agreement covers your destination, and what certificate proves the coverage, is something to confirm with the National Insurance Institute (Bituach Leumi) before departure.
Where no agreement applies, the employee and the employer may face contributions in both countries. The employment contract should say who bears the extra cost, and the budget for the assignment should include it.
Keep the confirmation from Bituach Leumi and any certificate issued by the host authority in the employee's file. The host country's inspectors can ask for it on site.
Work authorisation, employment terms and the company's exposure
Most countries require a visa or work permit even for short business assignments, and the rules depend on the activity. Attending a meeting is different from installing equipment or managing a local team; the latter often needs a permit.
Host-country labour law may set minimum standards for pay, working time or accommodation for workers posted to its territory. Your employment contract should reflect the stricter of the two sets of rules.
An employee who signs contracts or manages a local team can create a permanent establishment for the Israeli company, which would make part of its profit taxable in the host country. Tax advisers evaluate that risk before the assignment, not after the first tax notice arrives.
Example: an engineer sent to Munich for six months
An Israeli software company sends a senior engineer to its German customer for six months. HR opens the checklist two months before the start date. The accountant models the employee's tax in both countries and confirms with the National Insurance Institute whether an agreement keeps the employee insured in Israel.
The employee receives an assignment letter that sets the dates, the allowance, the housing arrangement and the rules on travel home. The company arranges the permit with the German side and confirms in writing which activities are allowed under it.
During the assignment, the engineer keeps a day log, and HR updates leave and timesheets as usual. At the end, the company reviews whether the extension is likely, because a longer stay may change the tax and social-security position and must be dealt with before the original period expires.
Remote work across borders
Many employees now ask to work from another country for a few weeks. This is a posting in everything but name: tax residency, social security and permanent establishment questions arise even if the employee works only on a laptop.
Adopt a written policy that sets a maximum number of days per year and per country, requires prior approval and lists countries where remote work is not allowed. Exceptions go through the same checklist as assignments.
Monitor the day counts. A few extra weeks across two years can push an employee over a threshold in a host country, and then the company must register and report, sometimes with retroactive effect.
Prepare an assignment letter that sets out dates, location, duties, pay, allowances, travel and housing, the tax and social-security treatment, and who covers costs. Update it if the assignment is extended.
Track the days spent in each country. Many tax and social-security rules turn on day counts, and the data is hard to reconstruct from memory. A simple log kept by the employee and approved monthly is enough.
4softhr.net holds employee records, leave and timesheets, and can store the day log as part of the record. It does not handle posting scenarios, does not decide social-security treatment and does not issue certificates; those come from Bituach Leumi and the host authorities.
