Starting a business in Greece? One of the very first things you need is a φορολογική έδρα — a registered tax seat. It's the official address tied to your business for tax purposes, and it appears on every invoice, tax return, and official document you produce.
Whether you're a freelancer, founding an IKE, or registering a sole proprietorship, the process is the same: you need an address, and you need to declare it to the tax authority. This guide walks you through the entire process — step by step.
What Is a Φορολογική Έδρα?
A φορολογική έδρα (tax seat) is the officially declared address where your business conducts its primary administrative and economic activity. It's defined under Law 4987/2022 (the Greek Tax Procedure Code) and registered with AADE (the Independent Authority for Public Revenue).
This address appears on:
• All invoices and receipts you issue
• Your tax returns and filings
• The GEMI commercial registry (publicly searchable)
• Your myDATA records
• Any official correspondence with the tax authority
In short: it's your business's legal home.
The Taxisnet Declaration Process — Step by Step
Declaring your tax seat is part of the έναρξη εργασιών (commencement of business activity) process. Here's how it works:
Step 1: Secure your address. Before you can register, you need a valid address with one of the following: a lease agreement (μισθωτήριο) registered electronically on Taxisnet by the landlord, a free-use declaration (δωρεάν παραχώρηση) with a sworn statement from the property owner, or proof of property ownership (via E9 declaration).
Step 2: The landlord registers the lease. If you're renting (or using a coworking address), the landlord must submit the lease electronically on Taxisnet within 30 days of signing. This is a legal requirement — without it, the lease isn't valid for tax purposes.
Step 3: Submit your business commencement. File the M2 form (for natural persons/sole proprietors) or M3 form (for legal entities like IKE or OE) through myAADE. You'll reference the registered lease and declare your activity codes (KAD).
Step 4: Receive confirmation. Once processed, your business is registered with your declared tax seat. You'll receive your tax registration confirmation and can begin issuing invoices.
As of 2026, much of this process can be completed electronically through myAADE, though some cases may still require a visit to your local DOY (tax office).
Your Options: Home, Traditional Office, or Coworking
When choosing your tax seat, you have three main options. Each comes with trade-offs.
Option 1: Home address. Using your home is only permitted for service-based activities (παροχή υπηρεσιών) — not for commercial or retail activities (αγοραπωλησίες). Even when allowed, only a proportional share of household expenses can be deducted as business costs. And your home address becomes public through GEMI and appears on every invoice.
Option 2: Traditional office lease. A dedicated office gives you full flexibility on activity types and full cost deductions. But in Drama, a basic 30 sqm office runs €200-300/month in rent alone — before utilities (€80-150), internet (€35-50), cleaning (€100-200), and heating in winter (€70-115). Total: €500-800/month, locked into a minimum 3-year lease with a 1-2 month deposit.
Option 3: Coworking / virtual address. A coworking space provides a fully legal tax seat through a proper lease agreement (μισθωτήριο) registered on Taxisnet — just like a traditional office. You get a professional city-center address, mail handling, and full cost deductibility, at a fraction of the price. No multi-year lease commitment.
Why a Coworking Address Is the Smart Choice
For most modern businesses — freelancers, remote workers, IKE founders, e-shop owners — a coworking-based tax seat offers the best of all worlds:
• Fully legal: A proper lease agreement is filed on Taxisnet, meeting all AADE requirements
• Professional image: A city-center address on your invoices and GEMI listing
• Privacy: Your home address stays private
• Cost-effective: A fraction of what a traditional office costs
• Flexible terms: 6 or 12-month agreements instead of 3-year leases
• Full deductibility: The entire cost is a deductible business expense
• Mail handling: Your business correspondence is received and held for you

Frequently Asked Questions
Can I use a coworking address for an IKE or OE? Yes. Our address is valid for all business types — sole proprietorships, IKE, OE, and more. We provide all documentation needed for GEMI registration and Taxisnet.
Is a home address always an option? Only for service-based activities (παροχή υπηρεσιών). If your KAD includes commercial activities, you need a professional address. Even for services, your home address becomes publicly visible.
What if I change my address later? You can change your tax seat by filing an update with AADE. The new landlord registers the new lease on Taxisnet, and you submit the change through myAADE.
Does the address appear on my invoices? Yes — Greek law requires your business address on all invoices and receipts. Since February 2026, B2B e-invoicing via myDATA is mandatory, and the address is a required field.
