    Why a 78% coefficient for an interior designer?

    Interior design is ATECO division 74 → 78%, the professional coefficient.1

    Professional, scientific & technical (78%). Pure-service professions (consulting, design, engineering, translation, teaching, health, finance) have little cost of goods, so the law assumes 78% of revenue is profit and taxes that share.

    Eligibility & cross-border traps

    • Buying and reselling furniture for clients is a trade activity (40%) — keep it separate from your design fee.
    • Site-supervision overlapping with construction (division 41–43) is a different, 86% activity.

    The €85,000 limit, the 5%/15% substitute tax and the rules above come from the forfettario law; newly-arrived residents should also check the impatriati regime.45

    Frequently asked questions

    What coefficient applies to an interior designer?

    78%. Interior design (ATECO 74.13) is in the professional group.

    Can a foreigner open a partita IVA as an interior designer in Italy?

    Yes. EU citizens can register a partita IVA directly; non-EU citizens generally need a valid residence permit that allows self-employment. The forfettario regime itself is open to residents regardless of nationality, subject to the €85,000 revenue limit and the other eligibility rules.

    How is the forfettario tax calculated for an interior designer?

    Your taxable base is revenue × the 78% coefficient for ATECO 74.13.00. INPS Gestione Separata (26.07%) is charged on that base and is deductible, then a 5% (first 5 years) or 15% substitute tax applies — replacing IRPEF, its surcharges and VAT.

    What happens above €85,000 revenue?

    Crossing €85,000 ends the forfettario from the following year and moves you to the ordinary regime (regime ordinario), where progressive IRPEF applies. Newly-arrived residents may instead benefit from the impatriati regime.
