How DIRT Affects Your Returns
| Gross Rate | DIRT (33%) | You Keep | |------------|------------|----------| | 3.00% | 0.99% | 2.01% | | 2.50% | 0.83% | 1.68% | | 2.00% | 0.66% | 1.34% | | 1.50% | 0.50% | 1.01% | | 1.00% | 0.33% | 0.67% | | 0.50% | 0.17% | 0.34% | | 0.25% | 0.08% | 0.17% |

DIRT Calculator
Quick Formula
After-tax interest = Gross interest × 0.67Examples
€10,000 at 2% for 1 year:- Gross interest: €10,000 × 2% = €200
- DIRT (33%): €200 × 0.33 = €66
- You receive: €200 - €66 = €134
- Gross interest: €50,000 × 3% = €1,500
- DIRT (33%): €1,500 × 0.33 = €495
- You receive: €1,500 - €495 = €1,005

What's Exempt from DIRT?
1. State Savings (Fixed-Term Products and Prize Bonds)
State Savings' fixed-term products and Prize Bonds are DIRT-free (the State Savings Deposit Account is not):
| Product | Gross Rate | Taxed Equivalent | |---------|------------|------------------| | 10-Year Bond | 2.66% | 3.97% | | 5-Year Certificate | 2.29% | 3.42% | | Savings Bond (3-year) | 1.96% | 2.93% |
To compare: Divide State Savings rate by 0.67 to get taxed equivalent. Example: 2.29% tax-free ÷ 0.67 = 3.42% gross rate needed to match it.2. Over-65s Exemption
If you or your spouse is 65+, you may be exempt from DIRT on interest up to:
| Status | Exemption Limit | |--------|-----------------| | Single, 65+ | €18,000 income | | Married, one 65+ | €36,000 income |
If your total income (including interest) is below these limits, you can claim DIRT back.
3. Permanently Incapacitated
Those who are permanently incapacitated may also be exempt.
4. Non-Residents
If you're not Irish tax resident, you may be exempt. Inform your bank and provide documentation.

DIRT and Neobanks
Bunq, Trade Republic, Revolut, N26
Whether each one deducts DIRT for Irish residents:
| Provider | Deducts DIRT? | Guarantee Country | |----------|---------------|-------------------| | Bunq | ❌ No (self-declare) | Netherlands | | Trade Republic | ❌ No (self-declare) | Varies by partner bank | | Revolut | ✅ Yes | Lithuania or Germany | | N26 | ❌ No (self-declare) | Germany |
Revolut deducts DIRT for you, so you don't need to do anything there. Bunq, Trade Republic and N26 don't, so declare that interest on your tax return.
Raisin (EU Banks)
Raisin does NOT deduct DIRT at source. You must:

Comparing Tax-Free vs Taxed Accounts
Is State Savings Better Than Bunq?
Let's compare:
| Account | Gross Rate | After DIRT | Access | |---------|------------|------------|--------| | Bunq | Up to 3.11% | 2.08% | Instant | | State Savings 5-Year | 2.29% | 2.29% | 5 years |
State Savings wins on rate (2.29% vs 2.08%) Bunq wins on access (instant vs 5-year lock)Break-Even Calculation
What gross rate do you need to beat State Savings after DIRT?
Formula: State Savings rate ÷ 0.67 = Required gross rate| State Savings Product | Tax-Free Rate | Taxed Rate Needed to Match | |-----------------------|---------------|---------------------------| | 5-Year Certificate | 2.29% | 3.42% | | 10-Year Bond | 2.66% | 3.97% | | Savings Bond (3-year) | 1.96% | 2.93% |
Finding: No instant-access account currently beats State Savings 5-Year on an after-tax basis. But Raisin's best 3-year fixed term (3.35%, 2.24% after DIRT) beats the 3-year Savings Bond (1.96%).---

Note: DIRT was gradually reduced from 41% to 33% between 2014-2020 and has remained at 33%. Future changes are possible.Why DIRT Exists
DIRT ensures savings interest is taxed, as it's technically income. The automatic deduction means most people don't need to file separately for bank interest.

Common DIRT Mistakes
Mistake 1: Comparing Gross Rates Only
Wrong: "Bunq at up to 3.11% is better than State Savings at 2.29%" Right: After DIRT, Bunq gives up to 2.08% while State Savings gives 2.29%Mistake 2: Ignoring Raisin Tax Obligations
Raisin interest must be declared. Not declaring is tax evasion.
Fix: Keep records, declare on tax return, pay DIRT owed.Mistake 3: Not Claiming Exemption
If you're over 65 with low income, you may be leaving money on the table.
Fix: Check eligibility, submit Form 54 to your bank.Mistake 4: Thinking Credit Union Is Exempt
Credit union dividends are subject to DIRT. They're not tax-free.

Practical Tips
1. Always Compare After-Tax Rates
Before moving money, calculate the after-DIRT return:
- Gross rate × 0.67 = After-DIRT return
2. Consider State Savings for Long-Term
If you won't need money for 5+ years, State Savings often beat taxed alternatives.
3. Don't Forget to Declare Raisin Interest
Revenue can see EU bank information via automatic exchange. Declare it properly.
4. Check Over-65 Exemption
If you or your spouse is 65+, investigate DIRT exemption eligibility.
