With regard to inheritance and gift tax, it is particularly important for businesses and companies to know of and use mechanisms and structuring options to reduce burdens in the event of an inheritance. Both in the run-up to the bestowal of the inheritance and afterwards, you have certain options available to you, such as a lifetime gift, a tax-optimised will, the assertion of compulsory entitlements or renouncement of the inheritance. These options can prevent the encumbrance of the inheritance from leading to real estate having to be sold or businesses being unable to continue operations.

In most cases, it is worthwhile for employees to file an income tax return, even if there is no obligation to do so. Employees can often obtain a tax refund through income-related expenses, lump sums and other deductions. Many individuals whose income exceeds the basic tax-free amount are obliged to file a tax return to their competent tax office within the legally stipulated period. Furthermore, employees must file an income tax return if, for example, one of the following points applies to you:

Receipt of wages from several employers
Additional income or income of more than €410.00
Spouse selects the income tax combination III/V or entry of the factor in tax class IV

        Mein Geschäftspartner und ich wurden sehr professionell bei einem ersten Treffen aufgeklärt. Alle unsere Fragen wurden in einer lockeren und wertschätzenden Atmosphäre beantworten. Die bisherige Betreuung und die Kontakte haben uns bei unserem gemeinsamen Vorhaben sehr weit nach vorne gebracht, so dass wir mit einem sehr guten Gefühl, hinsichtlich der Zusammenarbeit, in die Zukunft schauen. Nur zu empfehlen!!!
