Personal Income Tax Rates – Employment Income	Progressive tax rate: 0% – 50% (+ communal taxes). There are some tax free personal allowances available for Belgian residents and some non-residents.
Tax rate	See above.
Tax period	Calendar year.
Tax residency / Domicile according to domestic law	Belgian internal tax law provides two criteria whereby a person could be considered to be a Belgian tax resident, for example individuals who have established their domicile or the seat of their fortune in Belgium. The place of residence is normally governed by a number of factual criteria and is generally defined as the place where an individual has its permanent home. An individual is considered a resident of Belgium if the main home or centre of economic interests is in Belgium. An individual is presumed to be a resident of Belgium when registered in the civil register (rebuttable presumption). Married persons are deemed to be residents of Belgium if their household is established in Belgium (irrefutable presumption).
Tax registration	A registration is required in order to get registered as a Belgian tax payer and obtain a national (identification) number for income tax filing purposes.
Employment income definition	Any remuneration and benefit in cash or in kind received by an employee for services rendered under an employment agreement (e.g. benefits in kind, cost of living allowances, home leave reimbursements, housing allowances, company car, etc.). Exceptions could occur in case of non-residents benefitting from the special tax status for foreign executives.
Examples of tax exemption	Amongst others reimbursements of properly documented business expenses (including business trip expenses, per diems, etc.) are not taxable. Also certain tax free allowances and travel exclusion in view of the special tax status for foreign executives are not taxable.
Specific expatriate concession	Belgium offers a very favourable tax regime for expatriates coming to Belgium. Under this special tax status, non-Belgian executives and employees who ‘temporarily’ carry out work in Belgium qualify for special tax benefits. Qualifying individuals are treated as non-residents for Belgian tax purposes and are liable to Belgian income tax only on their Belgian-sourced income (i.e. earned income, Belgian investment income and income from real estate located in Belgium). All non-Belgian sourced income is not considered as taxable income in Belgium. In order to benefit from this special tax status, a special application should be made and sent to the Belgian tax authorities within six months after the month of the start of the employment in Belgium, and should be approved by the tax authorities. This special tax status essentially provides two main benefits that are relevant for calculating taxable income: 1. There is a number of tax free allowances deemed to cover the reasonable additional expenses associated with being employed in Belgium. This allowance is tax-exempt in Belgium up to an annual limit of € 11.250 (or € 29.750 in the case of eligible employees working at control and coordination offices, research centres and scientific laboratories). 2. Individuals qualifying for the special tax status are only taxed on the part of their income and remuneration for activities actually carried out in Belgium. The part of their worldwide income that corresponds with the days worked outside Belgium is totally exempt from Belgian income tax (i.e. through the application of a foreign travel exclusion).
Income of board members	The income of a board member will be taxed in the same way as regular employees. However, there are some slight differences with respect to the lump sump deduction of costs (if applicable) and the applicable social security contributions.
Tax returns	Each taxable person has to file a personal income return (July 16, 2020 via Tax on Web for residents). Depending on the residency status and a possible proxy for a chartered tax advisor different deadlines could be applicable (October 22, 2020 for residents, December 3, 2020 for non residents). In general, the return must be filed electronically by October of the year following the income year for residents and November of the year following the income year for non-residents.
Tax payments	The employer has the obligation to withhold the Belgian wage tax on the salary of the employee via the Belgian payroll or wage withholding tax returns (on a monthly or quaterly basis). Please note that an exemption could be possible if all conditions are fulfilled. The withheld wage tax will be settled with the Belgian income tax due on the basis of the annual personal income tax return.

Social Security Cost as % from gross salary and absolute amounts	In Belgium the social security contributions to be paid are different between employees and self-employed persons: *) Employees: The employer’s social security contributions differ for blue collar workers and white collar workers. The contributions are calculated based on gross wages (for blue collar workers it’s calculated on 108% of their gross wage and for white collar workers on 100%). Employer contributions equal approximately: – +/- 40% of the gross salary (x 1,08) for blue-collar (manual) workers. Please note that the effective percentage differs on the applicable joint labour committee; – +/- 25% of the gross salary of white-collar (professional and administrative) workers. Companies with fewer than 20 employees pay slightly less. The social security contributions are due on the gross salary (without limit). Certain salary elements are subject to a special contribution (e.g. the CO2 solidarity contribution for the private use of a company car or the contribution of 8,86% due on the employer’s group insurance contribution). The employee social security contributions, based on employee’s salary, amount to 13,07%. Each employee or worker is also liable to pay a special social security contribution on a monthly basis, which is capped. *) Self-employed: The social security contributions for self-employed are capped in Belgium to +/- € 17.000 per year (including administrative cost). 0% on income lower than € 13.993,79 20,50% on income between € 13.993,79 – € 60.427,75 (including on first € 13.993,79) and 14,16% on income between € 60.427,75 – € 89.051,37. Both social security contributions are tax deductible.
