Frequently Asked Questions
mBank or Santander for a freelancer?
Santander Bank Polska — most flexible B2B approach among major Polish banks. Accepts applications after 6 months of activity (mBank requires 12), analyses 3-month average, accepts revenue-based compensation for low months. For a freelancer with 1–2 years of B2B, Santander is usually the only route to a bank (most others would refuse).
Does mBank accept civil contracts?
Yes, but strictly. Required: 6+ months of tenure with the same contractor, 2,500+ PLN/month deposits, no contracting gaps. For many contractors with gaps (typical in IT, creative, teaching), mBank will refuse — Santander is then more flexible.
Which bank offers bigger amounts?
Santander Bank Polska — max cash loan 250,000 PLN (vs mBank 200,000 PLN). In practice, the difference matters only for very high income and long history. For loans above 200k PLN, a mortgage-backed loan is often better (lower RRSO, but requires collateral).
Does an account at mBank or Santander lower RRSO?
Yes — ROR customers get better cash-loan terms than external customers. mBank eKonto customers get 0.3–0.5 p.p. discount + faster decisions. Santander As-Nowy customers get 0.5 p.p. RRSO reduction in year 1 + free servicing during grace period.
How to choose between mBank and Santander when working in UK/Germany?
Santander Bank Polska — because it's part of Santander Group, which has branches in UK (Santander UK) and Germany (Santander Consumer Bank). For Euro/Pound income, Santander usually accepts statements from foreign Santander accounts as proof of income (mBank always requires sworn translations). For regular abroad work, this can save 2–3 weeks of application processing.
