Best High-Interest Savings Accounts in Poland 2026 — For Expats & Residents

Quick Answer (TL;DR)

Best promo rate in Poland (April 2026): Nest Bank at 8.00% gross (6.48% net after Belka), first 2 months, capped at PLN 50,000. Best rate with a large cap: ING Bank Śląski — 7.00% on up to PLN 200,000 for 4 months. Best for expats without PESEL: Revolut — open in minutes, multi-currency, 3.53% on PLN (higher with paid plans). Best tax shelter: an IKE savings wrapper — 4-4.5% gross with no 19% Belka at withdrawal after age 60. For Eurozone savers, best EUR rates sit at 2.0-3.5% (ECB deposit rate: 2.65%, April 2026); Polish PLN rates remain the highest in the EU.

Current Interest Rate Environment (April 2026)

The National Bank of Poland (NBP) reference rate stands at 5.75% as of April 2026, unchanged since early 2026. The ECB deposit facility rate sits at 2.65% — this is the single number that sets the ceiling for EUR savings accounts across Germany, France, the Netherlands, Spain, Ireland, and Italy. Context for 2026:

• Polish banks can offer promotional savings rates of 7-8% on new money; standard rates cluster at 4.5-5.5%
• The 19% Belka tax applies to all interest (6% gross = 4.86% net, 7% gross = 5.67% net, 8% gross = 6.48% net)
• Polish CPI runs at ~4.2% — so 5% net savings still preserves purchasing power, 4% does not
• ECB is on a slow easing path; EUR savings rates have drifted down from 3.5% peaks in 2024
• Rate forecasts for H2 2026: NBP likely to cut 25-50 bps if CPI keeps falling; EUR rates probably flat

Key formula: Net rate = Gross rate × 0.81 (Polish residents). A 6.00% gross rate gives 4.86% net after Belka.

Top Savings Accounts Compared (Poland)

1. mBank — eMax+ Savings Account

Why it's great: mBank has the strongest digital banking experience in Poland. The app is fully available in English, and you can open an account online with just a PESEL number and passport. The promotional rate of 7.00% (5.67% net) is among the highest available with a meaningful cap.

Watch out for: The 7% promo applies only for the first 3 months and only on new money (funds not previously held at mBank). After the promo, the rate drops to 5.00%.

2. ING Bank Śląski — Konto Oszczędnościowe

Why it's great: ING offers the most generous cap on the market — 7.00% for 4 months on up to PLN 200,000 is structurally the best deal if you have that kind of liquidity. Clean English app, expat-friendly onboarding.

Watch out for: The promotional rate requires opening a Konto Direct checking account and setting up a recurring inflow of at least PLN 1,000/month.

3. PKO Bank Polski — Konto Oszczędnościowe

Why it's great: PKO is Poland's largest bank — extremely safe, deeply established, the default option for salary-linked savers. The 150k cap and 6.50% promo are competitive.

Watch out for: The digital experience trails mBank and ING. Non-Polish speakers should expect friction — the mobile app doesn't have full English support, and many foreigners need a branch visit to open.

4. Revolut — Savings Vaults

Why it's great: Revolut is the lowest-friction option for expats — no PESEL required, onboarding in minutes, multi-currency (save PLN, EUR, USD simultaneously). Perfect if you earn in EUR and want PLN savings too.

Watch out for: The 3.53% Standard rate is meaningfully below Polish bank rates. Revolut savings are held in Lithuania and covered by the Lithuanian deposit guarantee (€100,000), not Polish BFG. The best Revolut rate requires Ultra (PLN 299/month) — only worthwhile on six-figure balances.

5. Nest Bank — Nest Savings Account

Why it's great: The highest promotional rate on the market — 8.00% gross (6.48% net) for the first 2 months. Ideal for parking emergency cash at peak rate before rotating.

Watch out for: 2-month promo window, 50k cap, standard rate drops to 5.00%. App and website are Polish-only.

6. Bank Millennium — Konto Oszczędnościowe Profit

Why it's great: Good promo rate, English app, expat-friendly onboarding — Millennium has actively targeted international clients for years.

Best for X — Decision Helper

• Best for emergency fund (instant access, no lock): mBank eMax+ or ING Konto Oszczędnościowe — English app, online opening, competitive standard rate after promo ends
• Best promo rate, short burst: Nest Bank at 8% for 2 months on up to 50k PLN — use it as the first leg of a hopping rotation
• Best no-strings offer: Revolut Vaults — 3.53% PLN, no cap, no PESEL, no income requirement, withdraw anytime
• Best for Revolut-linked salary: keep your checking in Revolut, sweep to Revolut Vaults; add an ING Konto Oszczędnościowe on top for the 7% promo on balances above 10k PLN
• Best for balances above PLN 200,000 (or €50k equivalent): split across ING (200k cap), mBank (100k), Millennium (100k) — each gets a separate BFG €100,000 guarantee, plus promo rates stack across accounts
• Best for PLN holders who need liquidity: Polish bank savings accounts beat EUR savings by 2-4 percentage points, even after Belka
• Best for EUR holders in Poland: Revolut EUR Vault (~2.0-2.5% on EUR) — saves FX costs if you earn in EUR
• Best for long-horizon retirement savings: skip standard savings entirely; use an IKE wrapper with either bonds (EDO/COI, tax-sheltered) or ETFs (VWCE via XTB IKE)

Polish Savings vs. Rest of Europe (April 2026)

Poland runs the highest real and nominal savings rates in the EU — this is structural, driven by NBP at 5.75% vs. ECB at 2.65%. Ballpark 2026 rates:

• Poland (PLN): 5-8% promo, 4-5% standard, BFG €100k
• Romania (RON): 6-7% promo, comparable central bank path
• Hungary (HUF): 5-6%, high FX volatility erodes real returns
• Czech Republic (CZK): 4-5% standard
• Germany: Trade Republic 2.75% on EUR, ING-DiBa ~2.5%, Scalable Capital ~2.6% on cash, Deutsche Bank ~1.5%
• Netherlands: bunq 2.01% on EUR (higher tiers), ING NL ~1.5%, ABN Amro ~1.5%, Revolut EUR Vault ~2.0%
• Spain: MyInvestor ~2.5% on EUR (promotional first-year), EVO Banco ~1.9% standard
• France: Livret A regulated at 3.00% tax-free (cap €22,950), LDDS at 3.00% tax-free (cap €12,000), standard bank savings 1.5-2.5%
• Ireland: Revolut EUR Vault ~2.0%, Trade Republic 2.75%, AIB/Bank of Ireland demand deposits 1-1.5%
• United Kingdom: Chase Saver 3.75% on GBP, Trading 212 Cash ISA 4.50%, tax-free up to £1,000 Personal Savings Allowance (basic rate)
• United States: Marcus by Goldman 4.20%, Ally 4.00%, SoFi 4.30% — FDIC covers $250,000

Key insight: A PLN saver at 5% net beats a Eurozone saver at 2.5% net by 2.5 percentage points — worth ~PLN 2,500/year on every 100k. The tradeoff is PLN/EUR FX exposure if you ever plan to spend in euros.

Strategy: Savings Account Hopping

Smart PLN savers use a rotation — open new promotional accounts every 2-4 months to always hold the top rate. The 2-hour payoff is usually PLN 500-2,000 per rotation.

The 12-Month Rotation

1. Month 1-3: mBank eMax+ → 7.00% on PLN 100,000
2. Month 4-7: ING Konto Oszczędnościowe → 7.00% on PLN 200,000
3. Month 8-10: Millennium Profit → 7.00% on PLN 100,000
4. Month 11-12: Nest Bank → 8.00% on PLN 50,000 + standard rate on the rest

Is It Worth the Hassle?

With PLN 100,000 at 7% (promo) vs. 5% (standard) for 3 months:

• Extra gross interest: PLN 100,000 × 2% × 3/12 = PLN 500 (PLN 405 net)
• Time investment: ~30 minutes to open the new account

That's roughly PLN 810/hour for your time — worth it for most people. Freenance tracks which accounts are live, which promos have expired, and total interest earned — so you don't lose track of seven tabs across six banks.

Best Savings Account for Expats in Poland

Tier 1: Best Overall for Expats

ING Bank Śląski — 7% promo, English app, online onboarding, PLN 200,000 cap. Best all-round package if you have PESEL.

Tier 2: Easiest Access (No PESEL)

Revolut — Open in minutes, EU/EEA ID only, multi-currency. Lower 3.53% rate but the fastest route to earning anything on your PLN while you sort out PESEL paperwork.

Tier 3: Best Rate with Full Cap

mBank — 7% promo, strong English app, 100k cap. Requires PESEL.

Getting a PESEL as an Expat

Most Polish banks require a PESEL (Polish national ID). EU/EEA citizens can get one at any city hall (Urząd Miasta) in ~30 minutes with a passport and address. Non-EU citizens typically get PESEL through their employer or tax registration (NIP).

Savings Accounts vs. Other Options

A savings account is the right tool for your emergency fund and short-horizon goals. Beyond 12 months, other vehicles beat it:

Rule of thumb:

• Emergency fund (3-6 months of expenses) → savings account
• Goals in 1-3 years → bank deposit or TOS bonds
• Goals in 5+ years → ETF in an IKE/IKZE wrapper
• Retirement → IKE + IKZE + PPK + ETFs

How Much Should You Keep in Savings?

Financial planners recommend 3-6 months of expenses in an easily accessible savings account. Polish monthly benchmarks:

Everything above the emergency fund should be invested for higher expected returns — 5% barely outruns 4.2% CPI.

Deposit Guarantee (BFG)

All Polish bank savings are protected by the BFG (Bankowy Fundusz Gwarancyjny) up to €100,000 per person per bank (~PLN 430,000 at current FX). Coverage includes savings accounts, checking accounts, lokaty, and accrued interest. Balances above €100k should be split across banks.

Revolut note: Savings in Revolut are covered by the Lithuanian deposit guarantee (also €100,000) — legally distinct from BFG, but equivalent scope.

Tax on Savings Interest (Belka Tax)

All savings interest in Poland is subject to the 19% Belka tax (podatek od zysków kapitałowych). It's:

• Deducted automatically by the bank — no annual PIT filing required for bank interest
• Applied to savings, deposits, bonds, dividends, capital gains
• Without any annual tax-free allowance (unlike UK's £1,000 PSA or Germany's €1,000 Sparerpauschbetrag)

Net Rate Quick-Reference

IKE Savings Accounts — Tax-Free Interest

A much underused option: the IKE (Indywidualne Konto Emerytalne) wrapper on a savings account. Interest compounds without Belka as long as you withdraw after age 60 (or 55 with 5+ years of contributions).

Net effect at 4.5%: regular account = 3.645% net (856 PLN/year on a 23,472 deposit), IKE = 4.5% effective (1,056 PLN/year) — 200 PLN/year free. Over 20 years of maxing the limit, the Belka savings compound into thousands.

IKE with ETFs will almost always outperform IKE savings on a 10+ year horizon. IKE savings makes sense only if you want zero risk and are within ~5 years of 60.

Interest Calculation — What You Really Earn

Scenario 1: Emergency Fund PLN 30,000

Scenario 2: Maximum Hopping — PLN 200,000 for 12 Months

Optimal rotation:

1. Months 1-4: ING 7% on 200k → 4,667 PLN gross
2. Months 5-7: mBank 7% on 100k + Millennium 7% on 100k → 3,500 PLN gross
3. Months 8-9: Nest 8% on 50k + standard 5% on 150k → 1,917 PLN gross
4. Months 10-12: standard 5% on 200k → 2,500 PLN gross

Total: ~12,584 PLN gross → 10,193 PLN net (effective 5.10% net). Compared to leaving 200k at a flat 5%: 10,000 PLN gross → 8,100 PLN net. Hopping earns ~2,093 PLN extra per year.

Why Not Excel for Tracking Savings?

A spreadsheet tracking six accounts across five banks with rotating promo deadlines becomes a part-time job in under three months. Every rotation needs: principal, start date, promo end date, standard fallback rate, interest-paid cadence. Miss one promo expiry and you silently lose 2 percentage points for months.

FAQ

How is savings interest taxed in Poland?

All savings interest is taxed at 19% Belka (podatek od zysków kapitałowych). The bank withholds it automatically at each interest payment — you don't declare bank interest on PIT. A 6% gross rate becomes 4.86% net. There's no annual tax-free allowance, unlike the UK (£1,000 PSA) or Germany (€1,000 Sparerpauschbetrag).

Is my deposit protected by BFG?

Yes — up to €100,000 per person per bank (~PLN 430,000) through the BFG (Bankowy Fundusz Gwarancyjny). Coverage includes savings accounts, checking, lokaty, and accrued interest. Split balances above €100k across multiple banks for full protection. US equivalent: FDIC at $250,000. UK equivalent: FSCS at £85,000.

What's the minimum deposit to open a savings account in Poland?

PLN 0 at every major Polish bank listed above. Promo rates kick in from the first PLN. The structural limits are the promo caps (50k-200k) and the standard income requirements at ING and some others (at least PLN 1,000/month recurring inflow).

Best savings account for an emergency fund vs. long-term savings?

Emergency fund (0-12 months): mBank eMax+ or ING — high standard rate, instant access, English app. Long-term (5+ years): don't use a savings account. Use an IKE with ETFs (VWCE via XTB IKE) or Treasury bonds (EDO 10y at 6.25%, CPI+1.25% from year 2) for tax-sheltered compounding.

Fixed vs. variable rate savings — which is better in 2026?

Most Polish savings accounts are variable rate (tracking NBP or bank discretion). Lokaty (bank deposits) typically offer fixed rates of 5-6.5% for 3-12 months. With NBP likely flat or cutting in H2 2026, locking in a 12-month lokata at 5.5-6% or TOS 3-year bond at 5.75% now may beat variable savings if rates fall.

Promo rate vs. standard rate — how much should I care?

The promo rate is roughly 2 percentage points above standard. On 100k PLN for 3 months that's PLN 405 net extra. Worth the 30-minute account opening, not worth chasing across 10 banks. A 2-3 account rotation covering 80% of the year captures most of the upside.

Revolut vs. Polish bank savings — which wins?

Polish banks win on rate (5-7% vs. Revolut's 3.53% PLN). Revolut wins on friction (no PESEL, minutes to open, multi-currency). Best combined setup: Revolut for daily spending + FX + EUR/USD Vaults, and a Polish bank (ING or mBank) for the bulk of your PLN emergency fund at 7% promo.

How often does the savings rate change?

Standard rates change when NBP changes its reference rate — typically with a 1-2 month lag. Promotional rates change monthly (banks compete on new-client acquisition). Check your bank's promo page at the start of each quarter, and re-run your rotation if a new top offer lands.

Is there a penalty for withdrawing from a savings account?

No — savings accounts (konto oszczędnościowe) are fully liquid, with no withdrawal penalty. Some banks limit free transfers to 1 per month and charge PLN 5-10 for additional transfers within the same month. Lokaty (fixed-term deposits) are different — early closure usually forfeits all or most interest.

Can non-residents open a Polish savings account?

Yes, but with friction. EU/EEA citizens need a PESEL (obtained at any city hall in ~30 min) and an address in Poland. Non-EU citizens typically need a residence permit or employer sponsorship. Revolut is the fastest workaround — no PESEL required, EU/EEA ID only, opens in minutes.
