being strategic with your cash savings and make your money work harder

While interest rates remain relatively elevated on both sides of the Atlantic and tax rules on savings interest stay largely unchanged, many savers are asking: should you stick with a regular savings account or look for more tax-efficient options?

Key Takeaways

Regular high-yield savings accounts and certificates of deposit (in the US) or term deposits (in Europe) offer attractive interest rates right now. However, the interest earned is generally taxable as ordinary income in both the US and most European countries.

Tax-advantaged accounts, such as IRAs or 401(k)s in the US and various national tax-efficient savings or investment accounts in Europe can help shelter some or all of your returns from tax depending on the rules in your country.

Consulting a financial adviser can help you decide how best to structure your cash holdings while interest rates remain supportive.

The higher interest rates available to savers since 2025 have provided welcome relief. Seeing your savings generate extra income at a time when many household budgets are still under pressure from elevated living costs can feel like a real boost.

In the United States, high-yield savings accounts (HYSAs) have become very popular, often offering rates well above traditional bank accounts. In Europe, savers have turned to competitive online banks, money market funds or fixed-term deposits, though rates vary significantly by country due to differences in ECB policy transmission and national banking markets.

Interest on regular savings accounts is taxed as ordinary income in the US (at federal rates up to 37%, plus any state taxes) and in most European countries (often at flat rates or as part of income tax, with some nations applying withholding taxes at source). This means that as rates have stayed higher for longer, more savers are seeing their tax bills on interest income rise noticeably.

The tax challenge for cash savers

This creates a Catch-22.
Higher interest rates are great for growing your balance but they also mean you may exhaust any available tax-free thresholds faster, with excess interest taxed at your marginal rate.

In the US, there is no general tax-free allowance for savings interest; all interest must be reported (via Form 1099-INT if $10 or more) and is taxed as ordinary income. Some retirees or lower-income households may benefit from lower brackets or other deductions.

Across Europe, tax treatment varies: some countries offer limited tax-free savings products (e.g., Livret A in France up to a cap), while others tax interest at source or through annual deemed-return systems (such as Box 3 in the Netherlands). The European Commission has been encouraging member states to introduce or expand simple Savings and Investment Accounts with tax incentives to channel more household savings into productive investments.

Savings account or tax-advantaged option?

A regular high-yield savings account provides liquidity and security (FDIC insurance up to $250,000 per depositor in the US; national deposit guarantee schemes up to €100,000 in the EU). However, the benefit of shifting money into tax-advantaged wrappers such as Roth or Traditional IRAs in the US or equivalent tax-efficient accounts in your European country often becomes clearer when you have longer-term goals.

What matters most is understanding your time horizon, liquidity needs and overall tax situation. A combination of both liquid cash savings and tax-efficient accounts can work well for many people.

Before moving money or opening new accounts, it is wise to speak with a financial adviser. As of April 2026, the US Federal Reserve has held the federal funds rate in the 3.50%–3.75% range, while the ECB has kept its deposit facility rate at 2.00%. Central banks on both sides of the Atlantic remain cautious with inflation still above target in the US (core around 3.2% projected for 2026) and closer to target but still monitored closely in the euro area.

Saving for the longer term

Liquid savings accounts remain essential for emergency funds or short-term needs easily accessible cash provides peace of mind.

For medium- to longer-term goals, many savers in the US and Europe are using their tax-advantaged contribution room (e.g., IRAs, 401(k)s, or national equivalents) more strategically. Shifting some allocation toward diversified investments inside these accounts can potentially deliver better after-tax returns over time, though this involves market risk and no guarantee of capital.

A financial adviser can help you combine different accounts effectively, making the most of available tax benefits while aligning with your personal circumstances and risk tolerance.

An investment in stocks and shares will not provide the same security of capital associated with a deposit with a bank or building society.

The levels and bases of taxation and reliefs from taxation can change at any time and are generally dependent on individual circumstances.
