Dual household in Germany: Accommodation costs are limited to 1.000 Euro per month – regardless of the size or location of the accommodation. Costs for furnishings and furniture are additionally deductible. Dual household abroad: The 1.000 Euro limit does not apply. The actual rental costs are recognised, provided they are reasonable. Reasonable costs are considered to be the local costs for a flat of up to 60 m². Additional costs are also deductible, but must also be converted to 60 m².
