Greece Freelancer Taxes in 2026: Surviving the Imputed-Income Squeeze and the October E-Invoicing Deadline

If you freelance in Greece, 2026 may tax you on money you never actually earned. Roughly 700,000 freelancers and self-employed professionals are caught in a peculiar squeeze this year: a minimum-wage increase quietly inflated the income the tax authority assumes you made, pushing up tax bills even for people whose real earnings stayed flat. And just as that bill lands, a second deadline arrives — from October 1, 2026, every B2B invoice you issue must flow through the myDATA platform or it does not count.

The good news: relief is already legislated, and some of it starts with your 2026 return. This guide walks through what changed, what it costs you, and the concrete steps to stay compliant and pay no more than you owe.

Why 2026 Hurts: The Minimum Wage Link​

Greece taxes many freelancers not on what they declare, but on a minimum imputed (presumptive) income calculated from objective criteria. The anchor for that calculation is the private-sector minimum wage — and on April 1, 2025, that wage rose from 830 euros to 880 euros a month.

That single change rippled straight into 2026 tax bills:

• Minimum imputed income rose from 11,620 euros (2024) to 12,320 euros (2025 income, taxed in 2026).
• Around 400,000 professionals are caught in this imputed-income trap, taxed on the deemed amount even when their books show less.
• The effect is automatic. You did not earn more; the formula simply assumes you did.

This is the core frustration of the system: imputed income is indifferent to a slow year, a lost client, or months between contracts. If your declared profit falls below the deemed floor, the floor wins.

How Imputed Income Works — and the 2026 Relief You Should Claim​

The minimum imputed income starts from a base tied to the minimum wage and is then increased by add-ons: years in business, staff payroll, and the turnover of your activity sector. Those add-ons are what made the system bite hardest for established professionals with employees or high-revenue sectors.

Here is where 2026 brings genuine relief. Under the tax package announced at the Thessaloniki International Fair in September 2026, compliant freelancers are exempt from the turnover-based and staff-payroll-based surcharges in the minimum-income calculation, starting with the 2026 tax year. Dropping those two add-ons can cut the deemed floor substantially.

But the exemption is conditional. To qualify you must:

1. File all your data through myDATA, the tax authority's digital platform.
2. Link your card terminal to your cash register so card receipts reconcile automatically.
3. Have a clean record — no tax or labour violations in the past five years.

Notice the pattern: every condition is about verifiable digital compliance. The government is trading a lower deemed income for full visibility into your real one. If you meet the conditions, make sure your accountant applies the exemption when your 2026 return is settled between mid-March and mid-July 2027 — it is new, and new reliefs are the ones most often missed.

Who Gets a Break in 2026​

Beyond the surcharge exemption, two existing reliefs soften the imputed-income hit:

The small-settlement discount​

Freelancers based in settlements outside the Attica region with up to 1,500 inhabitants get a 50 percent discount on imputed income. If you work remotely from a village, this is one of the largest single reductions available. From the 2027 tax year, the September 2026 package extends this 50 percent reduction to settlements of up to 2,000 residents.

The new-mother exemption​

Women practicing freelance professions are fully exempt from imputed-income calculations during their child's birth year and the following two years. If this applies to you, confirm the exemption is reflected before you accept any settlement based on deemed income.

2027 Brings the New Tax Scale: Lower Rates Across the Board​

The deeper fix arrives with 2027 income. A rewritten tax scale cuts rates for freelancers and self-employed professionals with profits above 10,000 euros:

• A 2 percentage-point cut in every bracket rate except the 9 percent introductory rate.
• A 39 percent top rate instead of 44 percent for incomes up to 60,000 euros.
• Zero tax up to 20,000 euros for freelancers under age 25, and for freelancers in large families.
• Freelancers aged 26 to 30 pay 9 percent instead of 22 percent on income from 10,001 to 20,000 euros.

The savings scale with income and family size. A professional with one child saves around 200 euros on 15,000 euros of income, rising to about 2,000 euros at 60,000 euros and above. With three children, the saving starts near 650 euros and can reach 3,300 euros at higher incomes.

Two more 2027 changes matter for cash flow. The advance tax payment for sole proprietorships falls from 55 percent to 50 percent — that is the prepayment you make against next year's bill, so the cut directly reduces what leaves your account. And the business activity fee is scrapped entirely in the regions and Thessaloniki from March 2027, with Attica following in stages. You will feel the new scale when 2027 returns are settled in 2028; employees see equivalent relief in their paychecks from January 2027, while the self-employed always wait for settlement season.

October 1, 2026: B2B E-Invoicing Becomes Mandatory for Everyone​

Running parallel to the tax-rate story is Greece's digital enforcement push — and its deadline is days away, not years.

Greece's Independent Authority for Public Revenue (AADE) runs myDATA, the national platform for electronic invoicing and digital tax reporting. Every invoice you issue must be transmitted to myDATA in a structured format, validated, and stamped with a unique registration number (MARK) that appears on the customer-facing invoice. Paper or plain-PDF invoices outside the system are invalid for VAT deduction and for accounting purposes.

The mandate rolled out in phases:

• September 1, 2025 — mandatory for B2G contracts with public entities over 2,500 euros.
• February 2, 2026 — mandatory B2B e-invoicing for large businesses with 2023 gross revenue above 1 million euros.
• October 1, 2026 — mandatory B2B e-invoicing for all remaining businesses, including every freelancer.

What this means for you in practice:

• B2B invoices must go through myDATA or AADE-certified software that integrates with it. There is no sector or entity-type exemption for small operators.
• B2C transactions remain voluntary — retail receipts to consumers do not require e-invoicing.
• You need a user ID and secret key from AADE to authenticate your billing software via API, and you must submit a Declaration of Commencement of Electronic Issuance to start.
• Non-compliance risks fines under VAT and accounting rules, loss of input-VAT deduction on off-system invoices, and exclusion from public tenders.

There is also a carrot: businesses and freelancers who adopted e-invoicing early qualified for tax incentives. And remember the link back to imputed income — filing everything through myDATA is now a condition for the turnover and payroll surcharge exemption. The two systems reinforce each other by design.

Your Action Checklist Before Year-End​

With the October deadline effectively here and settlement season following in spring, prioritize these steps:

1. Get myDATA-ready this week. If your invoicing software is not AADE-integrated, switch to a certified provider or connect your ERP and billing tools via the myDATA API now. Test that invoices return a MARK before October 1.
2. File the Declaration of Commencement of electronic issuance with AADE if you have not already.
3. Link your card terminal to your cash register. Beyond being good practice, it is one of the three conditions for the surcharge exemption.
4. Reconcile myDATA against your VAT returns. AADE cross-matches transmitted invoice data against filed returns automatically, and discrepancies flag you for audit. Make the two agree before the authority notices they do not.
5. Review your imputed-income position with your accountant. Confirm whether the turnover and staff-payroll surcharges should drop off your 2026 calculation, and whether the small-settlement discount or new-mother exemption applies.
6. Model your 2027 bill under the new scale. If you are under 30 or have children, the new rates may change decisions about timing income or expenses across the year boundary.
7. Budget for the lower advance payment. The 55-to-50 percent cut frees cash — plan where it goes rather than letting it evaporate.

Common Mistakes to Avoid​

• Issuing B2B invoices outside myDATA after October 1. Your client cannot deduct the VAT, and the invoice does not count in your books. This is the single costliest error a freelancer can make this autumn.
• Assuming B2C rules cover B2B work. Invoicing a company as a freelancer is a B2B transaction even if you are a one-person business. The mandate applies to you.
• Claiming the surcharge exemption without meeting all three conditions. Partial compliance does not earn partial relief — file via myDATA, link the terminal, and keep the five-year record clean.
• Ignoring the settlement-discount geography. The 50 percent small-settlement reduction depends on where you are based, not where your clients are. Remote freelancers should verify their registered base qualifies.
• Forgetting that relief lands at different times. Employees see cuts in January paychecks; you see them at settlement. Do not spend the 2027 savings before the 2028 settlement confirms them.

Keep Your Books Audit-Ready the Whole Year​

Greece's direction of travel is unmistakable: real-time digital reporting, automatic cross-checking, and tax relief reserved for the demonstrably compliant. The freelancers who thrive under this regime are not the ones with the cleverest deductions — they are the ones whose records reconcile to the euro across myDATA, VAT returns, and bank statements, every single quarter.

That is a bookkeeping discipline problem more than a tax problem. Tracking income and expenses in a transparent, version-controlled ledger you fully understand makes myDATA reconciliation a routine check instead of a spring panic.
