Two tax systems. One retirement account. If you’re a U.S. citizen living in Ireland, every withdrawal choice carries outsized consequences—and a few of them can quietly cost six figures. We break down the practical path to keeping more of your money while staying compliant on both sides of the Atlantic.
We start with the core problem: the U.S. taxes based on citizenship while Ireland taxes residents on worldwide income. The treaty helps but the saving clause means the U.S. still wants its slice. That’s where the foreign tax credit comes in. We walk through how to file, why USC matters for the credit, and why paperwork is the price of avoiding double tax. Then we split the planning conversation: traditional accounts are taxable in both countries, so the FTC is essential. Qualified Roth distributions, taken periodically, can be tax-free in both jurisdictions under Ireland’s Section 200—a rare and powerful advantage.
The game changes with lump sums. Since January 2023, Ireland’s Section 200A imposes a tiered tax on lump sums from foreign pensions, overriding the Roth-friendly rule. We map the brackets, show the math on a mid-six-figure withdrawal, and explain why the method of access can matter more than whether it’s Roth or traditional. From there, we dig into non-domiciled status and the remittance basis. If you’re resident but non-domiciled, Ireland only taxes foreign income when remitted—yet “remittance” includes far more than bank transfers. A Dublin ATM withdrawal, paying Irish bills with U.S. funds, or settling a U.S. card used in Ireland can all trigger tax.
To keep control, we outline the clean capital strategy: segregate pre-residency savings from post-move pension income. Avoid mixed funds that cause Irish Revenue to deem remittances as taxable first, trapping your clean capital. Set up two accounts before moving, use clean capital for living costs, and time pension remittances when the tax impact fits your plan. Along the way, we share clear takeaways: file for the FTC, favor qualified Roth periodic draws, avoid lump sums, and protect the remittance basis with strict account hygiene.
