Since 2013, civil litigation costs are only deductible if the taxpayer risks losing their means of subsistence and can no longer meet their basic needs (§ 33 para. 2 sentence 4 EStG). These are very strict conditions. It is not enough for the legal dispute to concern an important area of life; the loss of material means of subsistence must be imminent.
However, some courts have recognised legal expenses as exceptional costs in exceptional cases:
The Lower Saxony Finance Court has ruled that legal expenses are not deductible as exceptional costs if a taxpayer has suffered losses with online betting providers and claims them back in court – unless there is an existential emergency (ruling of 10.06.2025, ref. 13 K 157/24).
The appeal was allowed and is already pending before the Federal Fiscal Court under the reference VI R 10/25.
