For 2026 the old circular 11 still applies, which does not name laser eye surgery. Cantons such as Bern, Lucerne and St. Gallen already recognise laser treatment in their guidance; elsewhere the authority decides case by case. Submit the receipts in any event.<\/p>\n<\/details>\n<details>\n<summary>Does the circular also apply to cantonal and municipal taxes?<\/summary>\n<p>Circulars of the federal tax administration concern direct federal tax. The cantonal tax acts know the same deduction with their own thresholds, and in practice cantons usually follow the federal rule. That is not a guarantee; the cantonal guidance remains decisive.<\/p>\n<\/details>\n<details>\n<summary>What counts towards the costs?<\/summary>\n<p>Pre-assessment, procedure, medication and the check-ups, as far as you pay for them yourself. Glasses and contact lenses are medical costs too. Travel and accommodation are not deductible; the circular counts transport among living expenses.<\/p>\n<\/details>\n<details>\n<summary>What if supplementary insurance pays part of it?<\/summary>\n<p>Only what you bear yourself is deductible. Benefits from basic or supplementary insurance are deducted. Attach your insurer&#8217;s statement, even if it is a refusal.<\/p>\n<\/details>\n<details>\n<summary>Is the deduction worth it at all?<\/summary>\n<p>That depends on the threshold and your marginal tax rate. Anyone with further medical costs in the same year passes the threshold more easily. In the example above CHF 800 remain deductible for federal tax, CHF 3&#8217;500 in the canton of St. Gallen.<\/p>\n<\/details>\n<details>\n<summary>Does this apply to ICL lenses and lens exchange too?<\/summary>\n<p>The circular does not name lens procedures explicitly. The general principle for medical treatment to maintain or restore health applies. Whether the authority recognises this in an individual case we cannot promise. We issue the receipts identically.<\/p>\n<\/details>\n<details>\n<summary>Do I need a medical certificate?<\/summary>\n<p>For medical costs an invoice and proof of payment are usually sufficient. On request we issue a short medical confirmation of the diagnosis. The questionnaire mentioned in the circular is only needed for disability-related costs.<\/p>\n<\/details>\n<details>\n<summary>What if the treatment took place abroad?<\/summary>\n<p>The circular does not distinguish by place of treatment, but travel costs are never deductible. Whether an invoice from abroad is recognised is up to the tax authority.
