ROT tax reduction
A tax reduction on the labour cost when you pay a company to repair, maintain, rebuild or extend your home: a house, a tenant-owned flat or a holiday home you own. The company deducts the reduction directly on the invoice and claims the rest from Skatteverket, so you pay less at once.
The reduction only covers labour, not materials or travel, and there is a ceiling on how much can be deducted each year. You must own the home, or own a home your parents live in, and have paid enough tax to use the reduction; the amounts appear in your tax return.
Check that the company has F-tax and that the invoice shows the ROT reduction.
