Regno Unito — Calendario lavoro, stipendio e IVA

The United Kingdom operates a typical full-time week of thirty-seven to forty hours, although the Working Time Regulations cap the average working week at forty-eight hours unless the employee opts out in writing. The five-day Monday-to-Friday rhythm is universal in office work, and post-pandemic hybrid arrangements have become firmly established with most knowledge workers in the office two to three days per week.

Statutory paid leave is 28 working days per year (or 5.6 weeks) for full-time employees, which can include the eight UK public holidays. Most employers offer between twenty-five and thirty days of leave separate from public holidays, bringing typical office entitlement to thirty-three to thirty-eight days off per year including bank holidays.

Following the United Kingdom's withdrawal from the European Union, free movement of workers between the UK and EU member states ended in 2021. UK employers hiring EU citizens now generally need to sponsor a work visa under the Skilled Worker route, which adds administrative cost and processing time to international recruitment compared to the pre-Brexit regime.

The United Kingdom observes eight public holidays in England and Wales: New Year's Day, Good Friday, Easter Monday, the early May bank holiday on the first Monday in May, the Spring bank holiday on the last Monday in May, the Summer bank holiday on the last Monday in August, Christmas Day and Boxing Day. Scotland and Northern Ireland have slightly different lists, including Saint Andrew's Day in Scotland and Saint Patrick's Day and the Battle of the Boyne in Northern Ireland.

When a public holiday falls on a weekend, a substitute day is granted on the following Monday or the next working day. This rule means that the actual number of paid bank holiday Mondays in any given year is reasonably constant and easy to plan around, in contrast to systems where weekend holidays are simply lost.

The cluster of May bank holidays and the August bank holiday produces three guaranteed long weekends in the warmer months, which strongly influence the rhythm of school and family travel as well as office capacity. The Christmas to New Year stretch is widely treated as a quiet period in most office sectors, with a meaningful share of UK employees taking the full week off.

UK payroll combines a progressive income tax (PAYE) with rates of 20, 40 and 45 percent above the personal allowance, and the National Insurance contributions of 8 percent (employee, primary Class 1) above the primary threshold. Employer-side National Insurance (secondary Class 1) is 13.8 percent above the secondary threshold, plus an apprenticeship levy of 0.5 percent for larger employers.

The personal allowance is approximately 12,570 GBP for the 2025-2026 tax year, and the higher rate threshold begins at approximately 50,270 GBP. The threshold structure has been frozen for several years, which has produced a fiscal drag effect that pulls more employees into higher tax brackets each year as wages rise.

Auto-enrolment pension contributions are mandatory for most employers and employees: the minimum contribution is currently 8 percent of qualifying earnings (3 percent from the employer and 5 percent from the employee). Many employers offer a more generous pension scheme with employer contributions of 5 to 10 percent of salary, which is a meaningful component of total compensation.

The United Kingdom applies a standard VAT rate of twenty percent and a reduced rate of five percent for domestic energy, certain renovation work on residential property and energy-saving materials. A zero rate applies to most food, books, newspapers, children's clothing and prescription medication. The single reduced rate plus zero rate produces a simpler structure than many EU peers.

Following Brexit, the United Kingdom is outside the EU VAT system and the EU customs union. Cross-border B2B transactions between the UK and EU member states are now treated as exports and imports rather than intra-Community supplies, which means customs declarations and (depending on Incoterms) UK or EU import VAT apply on goods crossing the border.

The UK VAT registration threshold is 90,000 GBP in annual taxable turnover (raised from 85,000 GBP in 2024), which is the highest in the EU/EEA region. Above the threshold, registration is mandatory with quarterly or monthly returns through the Making Tax Digital (MTD) digital filing system.

When pricing a UK hire, factor employer National Insurance and the apprenticeship levy into the budget alongside the gross salary. Employer cost is typically around 13.8 to 14.3 percent above gross plus pension contributions, which is moderate by EU standards but still material for budgeting.

If your business sells to UK customers from an EU base, adapt invoicing and shipping logistics to the post-Brexit reality. Customs declarations, EORI numbers and either UK VAT registration or use of the IOSS scheme for low-value goods are all parts of the new operating model.

Plan around the August bank holiday and the Christmas-to-New-Year stretch. The August bank holiday weekend marks the end of the UK summer holiday period, and many businesses see a meaningful spike in activity in the first two weeks of September as the academic year resumes.
