Sellers of an owner-occupied home may defer the tax. They must buy or build a new Swiss home within two years before or after the sale. A holiday or second home does not count.

Only a Lucerne notary may certify the purchase contract. This can be a lawyer with an office in the canton, or a licensed municipal clerk.⁴
