Key figures — Greece, 2025

Every figure is drawn from this Guide and cited to its source.

Required inputs before computing

Before computing, you MUST obtain: 1. Professional category -- freelancer, sole proprietor, or liberal profession? 2. Years of activity -- determines minimum category 3. Chosen category -- new entrants start at 1; may choose higher 4. Is the client also employed? -- parallel insurance rules 5. Registered with which professional body? -- engineers, lawyers, doctors may have additional rules. If professional category is unknown, STOP.

R-GR-EFKA-1 -- Farmer transition

Trigger: client transitioning from OGA (agricultural) to freelance. Message: "OGA-to-EFKA transitional rules require specialist review. Escalate."

R-GR-EFKA-2 -- Professional body contributions

Trigger: question about bar/TEE/medical chamber rates. Message: "Professional body contributions are separate from EFKA and set independently. Confirm with the relevant chamber."

Prohibitions list

NEVER compute EFKA based on income -- the category system uses FIXED monthly amounts; NEVER allow a client to choose a category below their minimum based on years; NEVER ignore OAED (EUR 10/month) -- applies to all self-employed; NEVER confuse EFKA contributions with professional-body contributions; NEVER state parallel insurance allows an offset -- contributions are additive; NEVER advise on category optimization without flagging for reviewer; NEVER present contributions as income-dependent -- they are fixed per category; NEVER forget late payment surcharges -- 3% per month

Category choice rule

A professional can always choose a HIGHER category than their minimum, but never a lower one. Choice is made annually by February and is irreversible for the year.

OAED contribution

All self-employed: EUR 10/month in addition to category amounts.

ETEAEP

Some professions (lawyers, engineers, doctors) have additional professional-body contributions separate from EFKA.

Category selection strategy

Higher category = higher pension entitlement in retirement but higher current cost. Advising on optimal choice requires retirement benefit modelling. Flag for reviewer.

Determine minimum category

years_active = current_year - year_of_registration IF years_active <= 5: min_category = 1 ELIF years_active <= 10: min_category = 2 ELIF years_active <= 15: min_category = 3 ELIF years_active <= 20: min_category = 4 ELIF years_active <= 25: min_category = 5 ELSE: min_category = 6

Determine chosen category

chosen_category = max(client_choice, min_category)

Calculate contributions

monthly_total = pension[chosen] + health[chosen] + supplementary[chosen] + OAED (10) annual_total = monthly_total x 12

Late payment and non-payment

Late payment: 3% surcharge per month (capped at 100% of principal). Non-payment: KEAO debt collection.

Parallel insurance rule

Parallel insurance applies. Client pays EFKA on BOTH activities. No offset.

Suspension of activity rule

Must formally notify e-EFKA. No contributions during suspension. Health coverage continues up to 12 months after last contribution, then lapses.

Income does not affect contribution

Income level does NOT affect the contribution amount. Category minimums apply regardless.
