Workation & Taxes: 183-Day Rule, Deductions, A1

Subject to unlimited tax liability — even while traveling

Under Section 1 of the German Income Tax Act (§ 1 EStG), anyone with a residence (Wohnsitz) or habitual abode (gewöhnlicher Aufenthalt) in Germany is subject to unlimited income tax liability. For a typical workation, the residence (§ 8 AO, the German Fiscal Code) is the decisive point: it exists if you hold a home "under circumstances that indicate you will keep and use it" — a retained lease with a key is usually enough. As long as you keep that home, you remain subject to unlimited tax liability during your workation, no matter how long you are away. Habitual abode (§ 9 AO, more than six months), on the other hand, concerns stays in Germany — it determines when someone without a German residence becomes taxable here, and it plays no role for your trip abroad. Whether the destination country may also tax you is decided by the relevant tax treaty.

• § 1 EStG: a residence OR habitual abode in Germany → unlimited tax liability
• § 8 AO: a retained home = residence — tax liability continues during a workation
• § 9 AO (6 months) concerns stays in Germany, not the length of your trip
• Whether the destination country taxes too is governed by the tax treaty (183 days, employer, permanent establishment)
• Careful when subletting and handing over the keys: without a home and with a long stay abroad, your residence can lapse

The 183-day myth

The famous "183-day rule" comes from double taxation treaties (DBA, Doppelbesteuerungsabkommen). It only allocates taxing rights between states — it does not end German unlimited tax liability. Being "subject to unlimited tax liability" under § 1 EStG and being "resident" under a tax treaty are two different things: you can be liable to tax under both national laws at once; the treaty then only decides which state is actually allowed to tax. Also, the 183-day count is not standardized — the reference period (calendar year, tax year, or any 12-month period) varies by treaty. And 183 days alone are not enough: under the usual treaty pattern (Art. 15(2) of the OECD Model Convention), Germany keeps the sole right to tax your salary only if, in addition, your employer is not resident in the destination country and the salary is not borne by a permanent establishment (Betriebsstätte) of the employer there.

• A tax treaty does not automatically end German unlimited tax liability
• "Subject to unlimited tax liability" (§ 1 EStG) is not the same as "resident" (under a tax treaty)
• The 183-day reference period is defined differently in each treaty
• All three conditions required: max. 183 days, employer not resident there, salary not borne by a local permanent establishment

How the 183 days are really counted

What counts is days of physical presence in the destination country, not working days. Arrival and departure days, weekends, public holidays, and sick days all count. Anyone reading "183 working days" quickly miscalculates. The "any 12-month period" variant is the tricky one: two four-month workations, one in the autumn and one the following spring, can together cross the threshold even though each calendar year stays below it. If one of the three conditions fails, the destination country may tax the part of your salary attributable to the working days spent there. Germany then usually exempts that part (typically subject to the progression clause). You rarely pay twice, but you end up with two tax returns.

• Days of presence count, including arrival, departure, weekends, and sick days
• Check the reference period in the relevant treaty: calendar year, tax year, or any 12 months
• Add up multiple stays in the same country within 12 months
• If a condition fails: pro-rata taxation in the destination country, exemption in Germany

Permanent establishment: the risk lies with the employer

Under § 12 AO and Art. 5 of the OECD Model Convention, a permanent establishment (Betriebsstätte) is a fixed place of business through which a company carries on its activity. If one arises in the destination country, part of the company profit becomes taxable there, with registration, bookkeeping, and tax filings abroad. A hotel room or a flex desk for four weeks is not a fixed place of business. Two situations are critical: a permanent home office abroad, meaning months from the same apartment when your employer expects or requires it, and the dependent-agent permanent establishment (Art. 5(5) OECD Model), when you regularly conclude or negotiate contracts for the company locally. That tends to affect sales and management rather than developers. This is why many workation policies cap stays at 20 to 30 working days per year and country and prohibit signing contracts abroad.

• A hotel, holiday apartment, or coworking space for a few weeks usually does not create a permanent establishment
• Risk: a permanent home office abroad that your employer expects
• Risk: regularly concluding contracts locally (dependent-agent permanent establishment)
• Typical policy: 20–30 working days per year and country, no contracts signed abroad

Can you deduct workation costs?

A workation you choose yourself is usually a private matter for tax purposes. As an employee, you generally cannot deduct flights, accommodation, and coworking as work-related expenses (Werbungskosten), because the trip is privately motivated; your workplace at home or in the office is available to you. It is different if your employer sends you somewhere for business reasons, for example a team meeting or client appointment: then it is a business trip, whose costs your employer can reimburse tax-free or which you can otherwise claim as work-related expenses. For mixed trips, clearly work-related parts can sometimes be separated. The same logic applies to business expenses for the self-employed: only what is clearly work-related and documented is deductible. When in doubt, a tax advisor decides, not your travel plans.

• Self-chosen workation: travel and accommodation costs are usually private, not deductible
• Trip initiated by the employer: business trip, reimbursement or work-related expenses possible
• Mixed trips: only clearly work-related, separable costs
• Document receipts and working days, clarify your case with a tax advisor

A1 certificate: social security, not tax

The A1 certificate often comes up in the same breath but has nothing to do with taxes. It proves that you remain covered by German social security while working in the EU, EEA, Switzerland, or the United Kingdom. For a time-limited workation it runs via the posting rules; the German liaison body DVKA (Deutsche Verbindungsstelle Krankenversicherung – Ausland) explains the procedure. Formally there is no de minimis threshold. Details are in the social security guide.

• A1 governs social security, not income tax
• For employees, the employer applies, electronically only since 2025
• Intended even for short workations, no de minimis threshold

• Social security & A1
• Working remotely abroad

What can trigger tax in the destination country

Even if it subjectively feels like "just a short trip", the country where you work can have its own taxing claims — for example due to local working days, local residency, a permanent establishment of your employer, or local payroll tax obligations. It gets especially tricky if you acquire clients locally, sign contracts, or lead a local team on-site — that quickly creates connecting factors your employer never intended.

• Local working days and local residency can trigger tax liability
• Permanent-establishment risk: avoid a fixed place of business or signing contracts locally
• No local client acquisition, no local signing, no leading local teams
• Consider local payroll tax obligations early

Practical rules to avoid surprises

Most unpleasant surprises can be avoided with discipline. Keep stays short and clearly time-limited, avoid repeating them constantly in the same non-EU country, and document travel and working days carefully. From several weeks onward, it is worth coordinating with a tax advisor and your employer — not just once the tax office starts asking.

• Set an approved-country list together with your employer
• Keep stays short and time-limited, avoid repeating them in the same country
• Document travel and working days without gaps
• From several weeks onward: check payroll tax / permanent establishment with a tax advisor
