How this works
The reduced rate for home works looks simple, but the tax authority separates three checks: whether the property is effectively used as housing, whether the works fall under item 2.27, and how much incorporated materials weigh. This tool combines those checks and shows what is taxed at 6% or 23% before you accept a quote.
- 1
Check that the work is on housing
Item 2.27 only covers works contracts on properties or units used as housing: the property must be used as housing at the start of the work and continue to be used that way afterwards. It does not cover properties licensed for other purposes, vacant properties for sale/rent or properties used for business activity.
- 2
Separate eligible work from exclusions
Improvement, remodelling, renovation, restoration, repair and conservation may qualify. Cleaning, garden maintenance, pools, saunas, tennis/golf/minigolf courts, new construction, extensions, reconstruction and equipment supply stay outside this calculation.
- 3
Calculate the materials percentage
The tax authority looks at the total contract value. If incorporated materials are 20% or less of the total, the reduced rate can apply to the whole contract. If they exceed 20%, services are at 6% and materials at 23%, provided the invoice is itemised.
- 4
Read the invoice before accepting it
When the reduced rate is used, the invoice should identify the work owner, the property/unit and the reason for the reduced rate. If materials above 20% are charged as one global price without a split, the tax authority says the whole amount is taxed at the standard rate.
Frequently asked
Which home works can have 6% IVA?
In mainland Portugal, item 2.27 covers improvement, remodelling, renovation, restoration, repair or conservation works contracts on housing properties, with express exclusions. This tool starts from that rule and does not cover special regimes such as urban rehabilitation or affordable-housing construction.
If materials exceed 20%, do I always lose the 6% IVA?
Not necessarily. If the invoice splits services/labour from materials, the reduced rate can apply to services and the standard rate to materials. If there is only a global price, item 2.27 does not apply and the whole amount is at the standard rate.
Do kitchens, lifts or equipment qualify at 6%?
Official Circular Letter 30135 says the supply of lifts, escalators, heating, cooling, kitchens, fireplaces, domestic equipment and furniture does not fall under item 2.27 and is taxed at the standard rate, even if intended for a home.
Does this also work for Madeira and the Azores?
No. This calculator uses mainland rates: 6% and 23%. The autonomous regions may have their own rates; confirm the applicable rate on the invoice and in the IVA Code before deciding.
Does this replace checking with the contractor or accountant?
No. It helps check the general rule before accepting a quote or asking for a corrected invoice. Mixed cases, urban rehabilitation, partly residential properties, reverse charge, insurance claims or works under special regimes should be checked with a professional and official sources.
