When does the formal liquidation of a general partnership end the independence of the partners? A case study from the field of real estate investments
In its ruling of November 26, 2024, the Tax Appeals Court of the Canton of Zurich confirmed that a taxpayer can terminate his self-employment and thus claim liquidation gains taxation even if he buys a property from the previous business assets, has it renovated together with another property acquired from his brother and rents it out, as the activity associated with the two acquired properties is not a continuation of self-employment but serves as a private investment.
Declaration obligations, advisor liability and mitigation of penalties: hot topics in criminal tax law
If declaration obligations are breached - both in the mixed assessment procedure and in the self-assessment system - which lead to a (possible) tax reduction, the question of criminal liability regularly arises in addition to the levying of any additional tax. The representative of the taxable person is increasingly being targeted by the tax authorities.
Criminal tax law risks of tax advice
As the legally compliant fulfillment of tax obligations requires knowledge of tax law, which the taxpayer often lacks in whole or in part, many taxpayers seek help in fulfilling their declaration obligations. If there are declaration errors that lead to at least the threat of a tax loss, the involvement of a specialist does not release the taxpayer from their responsibility for their tax declaration. Conversely, the professional involved, the tax advisor, can also be targeted by the authorities responsible for prosecuting tax offenses.
