What is a high-yield savings account (HYSA)?

A high-yield savings account is a savings account that pays significantly above the national average APY. Online banks and fintech companies typically offer HYSAs because they have lower overhead. In 2026, top HYSAs offer around 4.5-5.0% APY with no lock-in period.

What is a certificate of deposit (CD)?

A CD is a time deposit that locks your money for a fixed term (3 months to 5 years) in exchange for a fixed interest rate, typically higher than a regular savings account. Early withdrawal usually incurs a penalty of 3-6 months of interest.

When is a CD better than a HYSA?

A CD is better when: (1) you know you will not need the funds before the term ends, (2) CD rates are higher than HYSA rates (common during rate-cut cycles), and (3) you want a guaranteed, locked-in return regardless of future rate changes.

When is a HYSA better than a CD?

A HYSA is better when: (1) you need flexibility to access funds, (2) rates are rising (HYSA rates adjust upward, CD rates are fixed), and (3) you are building an emergency fund. Most financial advisers recommend HYSAs for emergency funds precisely because of this flexibility.

Frequently Asked Questions

A HYSA is a savings account offered primarily by online banks that pays a significantly higher interest rate than a traditional savings account. HYSA rates in 2025 range from 4-5% APY at institutions like Marcus, Ally, SoFi, and Discover. They are FDIC-insured (up to 250,000 dollars) and allow penalty-free withdrawals at any time, making them ideal for emergency funds and short-term savings.

A CD is a savings product where you deposit money for a fixed term (typically 3 months to 5 years) at a fixed interest rate. US CDs are FDIC-insured and typically offer slightly higher rates than HYSAs in exchange for locking up your money. Early withdrawal penalties (usually 3-12 months of interest) apply if you need the funds before maturity.

Choose a CD when you have cash you will not need for a defined period and want to lock in the current rate. CDs are attractive when rates are high and expected to fall. Choose a HYSA when you need flexibility or are unsure of your timeline. For emergency funds, always use a HYSA since a CD penalty would defeat the purpose of liquid savings.

Yes. Interest earned in a HYSA or CD is taxed as ordinary income in the US in the year it is received (or in the year a CD matures for single-year CDs). Your bank will send a 1099-INT form. If you want to shelter savings interest from tax, consider a Roth IRA cash holding or I-Bonds, which defer federal tax and are exempt from state tax.

You can hold savings in a Roth IRA (after-tax contributions, tax-free growth) in cash equivalent funds to earn similar rates tax-free. I-Bonds from TreasuryDirect offer inflation-linked returns with federal tax deferral and state tax exemption. However, Roth IRA withdrawals before age 59.5 have restrictions on earnings. For straightforward tax-sheltered savings, these options are the primary US tools.

An easy-access savings account (also called an instant-access account) allows you to deposit and withdraw money freely without notice periods or penalties. Rates on the best easy-access accounts in 2025 are around 4-5% AER from providers such as Chase, Chip, or Moneybox. They are protected by the FSCS up to 120,000 pounds per institution.

A fixed-rate bond locks in your money for a defined term (typically 1-5 years) at a fixed interest rate. In exchange for reduced flexibility, you usually get a slightly higher rate than easy-access accounts. Early withdrawal is typically not permitted (or incurs a significant penalty). A fixed-rate Cash ISA offers the same structure with tax-free interest.

Choose a fixed-rate bond when you have surplus cash you will not need for the fixed term and want to lock in a high rate before rates fall. Choose an easy-access account for your emergency fund or any money you may need unexpectedly. The rate premium for fixing is typically modest (0.2-0.5%), so flexibility is usually worth prioritising unless rates are expected to drop significantly.

Interest is taxable, but most UK adults benefit from a Personal Savings Allowance (PSA) of 1,000 pounds per year (500 pounds for higher-rate taxpayers, zero for additional-rate taxpayers). Interest within the PSA is tax-free. Beyond the PSA, interest is added to your income and taxed at your marginal rate. A Cash ISA shelters all interest from tax regardless of how much you earn.

Use a Cash ISA if your interest income may exceed your Personal Savings Allowance (1,000 pounds per year for basic-rate taxpayers) or if you are a higher or additional-rate taxpayer. The ISA wrapper means all interest is permanently tax-free. If your interest is well within the PSA, a standard easy-access account with the best rate is equally effective and simpler.

A HISA is an Australian savings account that pays a higher interest rate than a standard everyday account, typically from an APRA-regulated bank or credit union. HISA rates in 2025 range from 5-5.5% per annum at institutions such as ING, Rabobank, and Macquarie. Most HISAs allow unlimited withdrawals. Balances are protected by the Australian Government Financial Claims Scheme up to 250,000 dollars per institution.

A term deposit locks your money with a bank or credit union for a fixed period (typically 1 month to 5 years) at a fixed interest rate. Australian term deposits are also covered by the Financial Claims Scheme. Early withdrawal is possible but usually requires notice and may incur an interest penalty. Term deposit rates in 2025 are broadly similar to or slightly above HISA rates.

Choose a term deposit when you have surplus savings you will not need for a defined period and want certainty about your rate. Term deposits are attractive when rates are high and expected to decrease. Choose a HISA for your emergency fund and any money you might need. The rate difference between the two is typically small (0.1-0.3%), so flexibility often outweighs the slight rate advantage.

Yes. Interest earned in a HISA or term deposit is included in your assessable income and taxed at your marginal rate in the financial year it is earned (or credited for term deposits). There is no Australian equivalent to the UK ISA for sheltering savings interest from income tax. You must declare savings interest on your tax return.

No. Superannuation is a separate retirement savings structure and you cannot directly hold a personal HISA inside it. However, you can direct your super to a cash or stable option within your fund, which earns similar returns but at the 15% concessional super tax rate rather than your marginal income tax rate, making it more tax-efficient for long-term savings.

A HISA is a savings account at a Canadian bank or credit union that pays a higher interest rate than a standard chequing or savings account. Canadian HISA rates in 2025 range from 4-5% per annum at online banks such as EQ Bank, Wealthsimple Cash, and Simplii Financial. CDIC-member HISAs are insured up to 100,000 dollars per depositor category.

A GIC is a Canadian savings product where you deposit money for a fixed term (typically 30 days to 5 years) at a guaranteed fixed interest rate. GICs from CDIC-member institutions are insured up to 100,000 dollars per depositor category. Cashable or redeemable GICs allow early access (usually after 30-90 days), while non-redeemable GICs lock in your money for the full term.

Choose a GIC when you have money you will not need for a set period and want to lock in the current rate before it falls. GICs are attractive in a declining rate environment. Choose a HISA for your emergency fund or any money with an uncertain timeline. Redeemable GICs offer a middle ground: a fixed rate with some withdrawal flexibility after the initial lock-in.

Yes, unless held inside a TFSA or RRSP. Interest earned in a non-registered HISA or GIC is added to your income and taxed at your marginal rate in the year it is received. For GICs spanning more than one year, interest is reported annually on an accrual basis. To shelter this income from tax, hold your HISA or GIC inside a TFSA for tax-free growth and withdrawals.

Yes, if you have TFSA room available, holding savings products inside a TFSA is almost always better than holding them in a non-registered account. All interest earned inside the TFSA is tax-free, and withdrawals can be made at any time without tax. EQ Bank and many other institutions offer TFSA HISAs and TFSA GICs, making it straightforward to combine tax efficiency with competitive rates.
