What you can deduct: expenses and deductible materials for workshop hosts

"I buy clay, glazes, brushes, I rent the space: how much can I deduct?". It's a perfectly fair question, but the answer surprises many: it depends on the tax regime you're in. The same expense, the same material, behaves differently depending on whether you're flat-rate, occasional or ordinary. Let's look at the three cases plainly. (Informational, not advice: do the precise math with your accountant.)

Case 1 — Flat-rate regime: no analytic deduction

In the flat-rate regime (the most common among VAT-registered artisans) you don't deduct individual expenses. Instead of analytic deduction there's the profitability coefficient: a fixed percentage, set for your ATECO code, that determines how much of revenue is taxable income. The rest is a lump-sum of costs already "discounted" upfront.

Concrete example: if your coefficient is 67%, on €10,000 of fees the tax authority treats €6,700 as income and the other €3,300 as lump-sum costs — regardless of how much you actually spent on materials. A reduced substitute tax then applies to that income. So: in the flat-rate regime buying more clay doesn't reduce taxes, because costs are already built into the coefficient. The upside is simplicity: you don't have to keep and account for every receipt as deduction proof.

Case 2 — Occasional work: you deduct documented expenses

Here everything changes, and it's an underrated advantage. In occasional self-employment (other income) you can deduct the expenses specifically incurred to produce that fee, as long as documented and inherent. If for that workshop you bought €40 of materials and collected them inside a €90 receipt, you tax the difference, not the full amount.

That means, as long as you stay in occasional work, it's worth keeping the receipts for materials tied to workshops: they concretely reduce taxable income. For the basics of this regime, start from the occasional self-employment guide.

Case 3 — Ordinary/simplified regime: full analytic deduction

If your activity grows and you move to an ordinary or simplified regime, you enter the classic business logic: you deduct inherent costs analytically. This includes much more than just materials:

• Raw materials and consumables (clay, yarn, paint, ingredients).
• Equipment and tools (with depreciation rules for durable goods).
• A share of the space costs (rent, utilities) if used for the activity.
• Marketing, website, training, professional insurance.
• Travel and other documented, inherent costs.

It's the regime with the most deductions but also the most obligations: it usually pays off when real costs are high relative to the flat-rate coefficient. Which one is better depends on your numbers, and it's exactly the conversation to have with your accountant looking at your real margins — which you can estimate with the calculators in your dashboard or by reading how much an artisan earns with workshops.

The quick table

• Flat-rate: you do NOT deduct expenses; the profitability coefficient counts. Maximum simplicity.
• Occasional work: you deduct documented expenses inherent to the single fee.
• Ordinary/simplified: full analytic deduction of all inherent costs, more obligations.

For the regulatory aspects (profitability coefficients, flat-rate regime, other income) the official reference is the Italian Revenue Agency. One thing holds for every regime: always keep your expense documents. Even where you don't deduct them right away, you need them if you change regime or in case of an audit.
