Invoices for Tradespeople: Mandatory Information, Material Costs and Tax Benefit
As a tradesperson, you have special requirements for your invoices. Learn how to separate labor and material, enable the tax bonus, and avoid typical mistakes.
As a tradesperson, you don't just issue invoices - you enable your private customers a significant tax benefit. The tradesperson bonus according to § 35a EStG brings your customers up to €1,200 per year back - provided your invoice meets the tax office requirements. In this comprehensive guide, you'll learn everything about the special features of tradesperson invoices: from the correct separation of labor and material to mandatory information to typical mistakes you should avoid.
The Tradesperson Bonus: Up to €1,200 Tax Benefit for Your Customers
The tradesperson bonus is a real sales argument. Private customers can deduct tradesperson services in their own household for tax purposes - and directly from the tax liability, not just from taxable income.
The Numbers in Detail
Tax reduction according to § 35a Para. 3 EStG:
- 20% of labor costs are directly deducted from tax liability
- Maximum €6,000 labor costs per year and household
- Results in maximum €1,200 tax savings per year
Calculation example:
| Item | Amount |
|---|---|
| Total invoice amount | €5,000 |
| Of which labor costs | €3,500 |
| Of which material | €1,500 |
| Tax bonus (20% of €3,500) | €700 |
The customer gets €700 back through their tax return. That makes your service effectively 14% cheaper!
What falls under the Tradesperson Bonus?
Deductible services (examples):
- Renovation: Painting and wallpapering, floor laying, tiling
- Repairs: Plumbing, electrical, heating, roof repairs
- Modernization: Window replacement, heating modernization, insulation
- Garden: Paving work, fence construction, tree felling, garden maintenance
- Maintenance: Heating maintenance, chimney sweep, elevator maintenance
- Installation: Fitted kitchens (assembly!), alarm systems, smart home
- Cleaning: House cleaning, window cleaning, building cleaning
Not deductible:
- New construction measures: Extension of living space (annex, attic expansion with more area)
- Material costs: Only labor costs are deductible!
- Manufacturing costs: Initial creation of facilities
- Services outside the household: Workshop work, manufacturing in business
- Expert activities: Architects, structural engineers (if not manual)
Household-related Services vs. Tradesperson Services
There are two different tax benefits that should not be confused:
| Aspect | Household-related Services | Tradesperson Services |
|---|---|---|
| Typical activities | Cleaning, cooking, garden care | Renovation, repair, modernization |
| Deductible | 20% of costs | 20% of labor costs |
| Maximum | €4,000 savings (€20,000 costs) | €1,200 savings (€6,000 labor costs) |
| Combinable? | Yes, both bonuses can be used in parallel |
Mandatory Information on the Tradesperson Invoice
In addition to the general invoice requirements according to VAT law, there are additional requirements for tradesperson invoices so that the customer can use the tax bonus.
The General Mandatory Information (§ 14 UStG)
You need this information on every invoice:
- Full name and address of the service provider (you)
- Full name and address of the service recipient (customer)
- Tax number or VAT ID
- Invoice date
- Sequential invoice number
- Type and scope of service (quantity, description)
- Time of service (service date or service period)
- Remuneration (net amounts per item)
- Tax rate and tax amount (or note on tax exemption)
- Gross total amount
Additional Information for the Tax Bonus
1. Separate disclosure of labor costs and material costs
This is the most important requirement! Without separate listing, the customer can't deduct anything.

What Counts as Labor Costs?
The delimitation is sometimes not clear. Here's an overview:
Clearly Labor Costs (deductible)
- Wage costs: Working hours of tradespeople
- Travel costs: Travel time and travel expenses
- Equipment rental: If used on-site (e.g., scaffolding, lifting platform)
- Disposal costs: Labor for removal
- Cleaning costs: Final cleaning after construction site
Clearly Material Costs (not deductible)
- Building materials: Tiles, paint, wood, pipes
- Sanitary objects: WC, washbasin, bathtub
- Electrical materials: Cables, switches, sockets
- Heating materials: Radiators, thermostats
- Consumables: Dowels, screws, seals
Borderline Cases
Tool wear / Tool use: Can be valued as labor costs if used on-site and not billed separately.
Small materials: At low value (under €50), the tax office often accepts allocation to labor costs. For higher amounts: Better break down.
Flat rates: For flat-rate offers, you must make a percentage allocation for the customer. Base on industry standards.
Payment: Non-cash is Mandatory!
The golden rule: Tax bonus only with non-cash payment.
Accepted Payment Methods
- Bank transfer (standard, recommended)
- Direct debit / SEPA mandate
- Card payment (EC card, credit card)
- Online payment (PayPal, Klarna, etc.)
- Crossed check (rare, but possible)
Not Accepted
- Cash payment (even with receipt!)
- Barter / exchange
What to do with customer request "cash payment"?
Many customers don't know the tax bonus or underestimate it. Explain kindly:
"I understand that cash payment is convenient for you. However, with bank transfer you can save up to €1,200 per year in taxes. For your invoice of €1,412 labor costs, that would be €282 savings. Should I give you the bank details?"
Most customers then choose bank transfer.
Down Payment Invoices and Final Invoice in Trades
For larger projects, partial payments are common. Here too, the rules must be observed.
Down Payment Invoices
On each down payment invoice:
- Separate labor and material costs
- State place of service
- Mark as "Down payment invoice"
- Note on pending final invoice
Example:
"1st down payment invoice for bathroom renovation Villenweg 42
Corresponds to approx. 50% of total order
Final settlement after completion"
Final Invoice
The final invoice must contain:
- Overall overview of all services
- Sum of all labor costs (total)
- Sum of all material costs (total)
- All received down payments
- Remaining balance
Structure:
Total bathroom renovation service: €5,250.00 net
- Total labor costs: €2,800.00
- Total material costs: €2,450.00
plus 19% VAT: €997.50
Gross amount: €6,247.50
Less received down payments:
- 1st down payment from 15.10.2025: -€2,000.00
- 2nd down payment from 01.11.2025: -€2,000.00
STILL TO PAY: €2,247.50
Avoid Typical Mistakes
Mistake 1: No separation of labor and material
Problem: The customer can't deduct anything and demands a corrected invoice.
Solution: Work structured from the start. Use invoicing software that automatically separates.
Mistake 2: Material costs proportionally too high
Problem: The tax office becomes suspicious when 80% of the invoice is for material (for typical tradesperson services).
Solution: Realistic allocation. If a lot of material is needed (e.g., expensive tiles), the ratio is correct - but document it plausibly.
Mistake 3: No place of service stated
Problem: Tax office refuses deduction because it can't be proven that service was provided in household.
Solution: Always state complete address where work was performed.
Mistake 4: Accept cash payment
Problem: Customer loses tax bonus, you have cash handling.
Solution: Kindly insist on bank transfer, explain benefit.
Mistake 5: Missing note on tax bonus
Problem: Not a legal error, but missed chance for customer loyalty.
Solution: Professional note text shows service orientation.
Mistake 6: Flat rates without breakdown
Problem: Customer can't deduct anything because no labor costs are visible.
Solution: Also show composition for flat rates.
Special Cases in Trades
Emergency service / Sunday work
Surcharges for emergency service, weekend or holiday work count as labor costs and are deductible.
Workshop services
Work performed in the workshop (not at the customer's) is not deductible. Example: Making a cabinet door in the carpentry.
Deductible: Assembly on-site. Not deductible: Production in the workshop.
Mixed households (private + commercial)
For partly commercially used buildings, the private portion must be determined. Only this is deductible via § 35a.
Apartment building / Condominium
For condominiums, each owner can deduct their share of labor costs. Property management often creates a certificate.

Frequently asked questions
How much can customers deduct from tradesperson services?
Private customers can deduct 20% of labor costs directly from their tax liability, maximum €1,200 per year (corresponding to €6,000 labor costs). Important: It's a tax deduction, not just a reduction of taxable income. Material costs are generally not deductible - that's why separate disclosure is so important.
Why must I separate labor and material?
Only labor costs are tax-deductible for the customer. Without separate disclosure on the invoice, the tax office can refuse the tax bonus because it's not visible what portion is for labor. The separation is not bureaucratic harassment, but a legal requirement for the deduction according to § 35a EStG.
Can the customer also use the tax bonus for cash payment?
No, the tax bonus according to § 35a EStG only applies for non-cash payment. The tax office requires proof of payment (bank statement, transfer receipt). For cash payment - even with receipt - the tax benefit is completely void. Explain this benefit to your customers, most will then gladly pay by bank transfer.
Do travel costs count as labor or material costs?
Travel and transportation costs clearly count as labor costs and are thus deductible for the customer. Travel time and mileage allowances also belong here. Show them in the category "Labor services", e.g., as "Travel: 2 x €45.00 = €90.00".
Does the tradesperson bonus also apply for new construction?
No, new construction measures are excluded from the tradesperson bonus. This applies to initial construction of a building or extension of living space (e.g., annex, addition). Once the building is ready for occupancy, later renovation, maintenance and modernization measures are again deductible. The transition from new construction to existing property is relevant.
How do I correctly show flat rates?
Even for flat rates, you must make a breakdown into labor and material costs for the customer. You can write, for example: "Flat rate bathroom renovation: €5,000 net, of which labor costs: €3,200 (64%), material costs: €1,800 (36%)". Base on industry standards or actual calculation.
What do I do for workshop work?
Work performed in your workshop (not at the customer's) is not deductible because it wasn't provided "in the household". Example: Making a cabinet door in the carpentry is not deductible, assembly on-site is. Show separately on the invoice which services were provided on-site and which in the workshop.
Must I note the tax bonus on the invoice?
There is no legal obligation to note. However, it is highly recommended and customer-friendly. A professional note like "The labor costs of €X can be claimed for tax purposes according to § 35a Para. 3 EStG" shows service orientation and increases the likelihood of being recommended. It also reminds the customer to pay non-cash.
