DIRT (Deposit Interest Retention Tax) is a withholding tax deducted from interest paid on Irish deposit accounts. The bank withholds it when interest is credited, and you receive the net amount.
The standard DIRT rate used by this calculator is 33%. Some products or personal circumstances may have different treatment, so treat this as an estimate.
In many common cases, yes. DIRT is typically withheld at source when interest is paid or credited. Your statement often shows gross interest, DIRT withheld, and net interest.
DIRT is deducted when interest is credited. With monthly crediting, DIRT is withheld monthly and net interest compounds sooner. With annual crediting, withholding happens once per year.
If you (or your spouse/civil partner) are aged 65 or over, the first €635 (single) or €1,270 (married) of annual deposit interest is DIRT-free. Enable "Over 65" in Advanced to see the savings.
Most deposit products are treated similarly for DIRT purposes. If the product calls the return "interest", DIRT withholding is common. Confirm with the provider for special cases.
You can use it as a benchmark for "what if the return is treated like deposit interest with DIRT withheld". Credit union share dividends are generally DIRT-free; deposit account interest is subject to DIRT.
Some State Savings products are treated as exempt from DIRT under current rules. Use this calculator to compare scenarios and cross-check with official product documentation.
Some people may qualify for an exemption or refund depending on income levels and circumstances (e.g., over-65 or permanent incapacity scenarios). Check Revenue guidance for your case.
No. DIRT is a separate withholding tax on deposit interest. It is distinct from payroll deductions like PAYE, USC, and PRSI, and does not apply to ETFs and shares.
No. Deposit interest is treated differently from investment gains under CGT rules. Use this tool for deposit interest scenarios, and use dedicated CGT or ETF tools for other investment types.
Enter the deposit amount, gross annual interest rate, and term. Set the interest credit frequency (monthly vs annually) in Advanced to see the effect of compounding and withholding timing.
It models a single upfront deposit with DIRT withholding. It does not model changing rates, fees, inflation, regular contributions, or every edge-case tax treatment for special products.
No. DIRT is withheld by Irish deposit takers. Foreign accounts do not withhold Irish DIRT, but you may still have an Irish tax obligation depending on your residence status.
