Yes, renting office space is fully deductible as business expenses in 2026, including rent, service charges, and facilities you use for your business. You can claim back both the rental costs and VAT, provided you are VAT-registered. Mixed use is also possible, where you deduct the business portion proportionally. For correct deduction, you need proper documentation, such as rental agreements and itemized invoices.
Which office costs can you exactly deduct from taxes?
All costs directly related to your office space are deductible, including monthly rent, service charges, utilities, cleaning, security, and facilities such as meeting rooms and internet costs. These costs fall under business expenses and directly reduce your taxable profit.
The main deductible office costs are:
- Rental costs: the monthly rent for your office space
- Service charges: cleaning, security, reception, and maintenance
- Utilities: gas, water, electricity, and internet costs
- Facilities: access to meeting rooms, coffee, and communal areas
- Parking costs: paid parking for your business
Note: personal expenses such as private meals or non-business facilities cannot be deducted. With all-inclusive office packages, it’s convenient that all business costs are clearly specified.
How does the VAT system work when renting office space?
As a VAT-registered entrepreneur, you can fully reclaim VAT on office rent through your VAT return. Office rent falls under the 21% VAT rate, and landlords are required to charge VAT on commercial office space. You get this VAT back as input tax.
Here’s how the VAT system works in practice:
| Situation | VAT Rate | Refund Possible |
|---|---|---|
| Commercial office rent | 21% | Yes, fully |
| All-inclusive service package | 21% | Yes, on all components |
| Facilities and services | 21% | Yes, if used for business |
With all-inclusive packages, VAT is calculated on the total amount. Ensure your invoices clearly specify all cost items so you can demonstrate during audits that everything is business-related. Professional office providers usually ensure correct VAT administration.
What are the tax rules for mixed use of office space?
With mixed use, you only deduct the business portion of your office costs. You calculate the percentage of business use based on time, space, or a combination of both. You apply this percentage to all office costs for correct tax deduction.
Calculate mixed use like this:
- Time basis: 80% business use = 80% of all costs deductible
- Space basis: 60% of space for business = 60% deductible
- Combination: use the method that is most realistic
Different rules apply for working from home than for external office space. With an external office location, you don’t need to prove private use: the space is specifically rented for your business. This often makes external office space more fiscally attractive than working from home with mixed use.
What documents do you need for your tax return?
For correct deduction, you need the rental agreement, all rent and service invoices, VAT specifications, and proof of payment. Keep these documents for at least seven years and ensure all invoices state your business name and VAT number for valid deduction.
These documents are mandatory:
- Rental agreement: with clear business purpose
- Monthly invoices: all rent and service costs
- VAT specifications: itemized per cost category
- Payment receipts: bank statements or payment confirmations
- Cost specifications: what’s included in all-inclusive packages
During tax authority audits, you must prove that costs are business-related. Therefore, also keep notes about the use of facilities and meeting rooms. Good administration prevents problems and ensures maximum deduction.
