Is CD Interest Taxed Before You Withdraw It?
It seems reasonable to assume that money locked away in a certificate of deposit doesn’t count as income until it’s actually withdrawn. The way interest gets taxed doesn’t work that way, and it surprises a lot of people.
The short answer
Interest earned on a CD is generally taxable in the year it’s earned or credited to the account, not the year it’s withdrawn — even for a multi-year CD where the funds stay locked up the entire time. This applies whether the interest is paid out periodically or simply accrues and compounds inside the account until maturity.
Why “constructive receipt” applies
The underlying tax concept is often called constructive receipt: if interest has been credited to an account and the account holder could access it (even if they choose not to, or even if withdrawing it early would trigger a penalty), it generally counts as income for that year. This is different from something like an unrealized stock gain, where value hasn’t been converted into cash or credited anywhere yet. A certificate of deposit’s interest is typically credited on a schedule set by the bank — monthly, quarterly, or annually — and each credit generally becomes taxable in that period.
What a 1099-INT means each year
For a CD spanning more than one calendar year, the bank typically issues a Form 1099-INT annually, reporting the interest credited during that specific year, even though no withdrawal happened and the CD hasn’t matured. That amount generally needs to be reported as taxable income on that year’s tax return, which can mean owing tax on money that’s still sitting in a locked account. This is a common source of confusion for people opening their first multi-year CD, who reasonably expect the tax question to wait until the funds are actually usable.
How this differs from what people assume
The mismatch between when interest is taxed and when it’s accessible is the core surprise here. A five-year CD that compounds interest the entire time will typically generate a 1099-INT in each of those five years, not one lump 1099 at the end. Because tax rules and reporting requirements are set by the government and can change, it’s worth confirming the current treatment with a tax professional or the IRS’s own guidance rather than relying on assumptions from a previous year’s return.
Comparing this to tax-advantaged accounts
CDs held inside a tax-advantaged account, such as an IRA, generally don’t trigger this same year-by-year taxable event, since the tax treatment of the wrapper account governs instead. A CD held directly in a regular taxable account doesn’t get that benefit, which is one factor some savers weigh when deciding where to hold longer-term CDs.
The bottom line
CD interest is typically taxed as it’s earned, not as it’s withdrawn, which means a locked-up CD can still generate a real tax bill along the way. Planning for that annual 1099-INT, rather than being caught off guard by it, is the more useful habit than assuming taxes wait until maturity.
