User guide and information
Usage in brief
- Yellow cells (blue text) are input cells. White cells are calculated by formulas – do not type over them.
- The example values (bathroom row, Contractor 1, spouses' labour shares, schedule durations) show the input format. Replace them with your own details.
- Check the contractor in YTJ (www.ytj.fi) and always confirm the quote and contract in writing. Ask for the labour portion to be itemised on the invoice.
HOUSEHOLD DEDUCTION 2026–2027 (revised 27 October 2026) Current values (Finnish Tax Administration, updated 13 October 2026): maximum €2,100 / person / year, deductible €150, work done by a company 40%, wages + ancillary costs 15%, for 2026–2027, retroactively for all work paid for in 2026. Giving up oil heating: 60%, up to €3,500 (until the end of 2027). Before 2026: maximum €1,600, work 35%, wages 13%. In the calculator you can choose the set of values: the default "2026–2027" corresponds to the current values, the "Before 2026" set to the earlier values. All values can be edited. The deduction applies only to the labour share (incl. VAT), not to materials.
