An IRA, or individual retirement account, for a given tax year can be funded during that year or by the tax-return due date without extensions. For most filers, 2025 contributions were due April 15, 2026, so contributing early offers more time in the account while waiting preserves cash but leaves no room for error, according to the IRS in Publication 590-A contribution rules. This guide compares those timing choices, the tax difference between Traditional and Roth accounts, and the main cost and risk traps. Use it to pick an account type, stay within the limit, and tag the correct tax year.

When does your contribution count?
You can contribute for the current year at any point during that calendar year. You can also contribute from January 1 to April 15 of the next year and count it for either year. A tax-filing extension to October 15 does not extend the prior-year IRA deadline.
The IRS ties Traditional and Roth contributions to the original April due date in Publication 590-A deadline rules. Early action gives a longer growth window and spreads paperwork across the year. Late action lets you confirm income, workplace-plan coverage, and cash flow before you commit funds.
How much can you put in?
The combined limit for all your Traditional plus Roth IRAs is $7,000 for 2025 if you are under 50. It rises to $7,500 for 2026 if you are under 50, with catch-up amounts of $1,000 and $1,100 at age 50 and older, according to the IRS in COLA limit tables. The limit applies across accounts, not per account.
A $4,000 Traditional contribution plus a $3,000 Roth contribution reaches the $7,000 cap for 2025 for someone under 50. Your contribution also cannot exceed your taxable compensation for the year. A spousal-IRA rule lets a working spouse use their compensation to support a nonworking spouse's contribution.

Should you choose Traditional or Roth?
A Traditional IRA may be fully or partly deductible based on income and workplace-plan coverage. Amounts including earnings are generally taxed only upon withdrawal. A Roth IRA never gives a deduction.
Qualified distributions including earnings are tax-free, and owners face no required withdrawals during their lifetime. Pick Traditional when a current deduction matters most and you expect withdrawals to be manageable. Pick Roth when you prefer tax-free qualified withdrawals later and want no lifetime required withdrawals.
What mistakes raise costs and risk?
Contributions made January 1 to April 15 must be designated for the prior or current year. If you stay silent, the custodian may report it as a current-year contribution to the IRS. That error can waste prior-year space you cannot recover after April 15.
Other common errors include exceeding the combined limit and exceeding compensation. Early distributions from Traditional or Roth IRAs before age 59½ incur a 10% additional tax on the taxable portion unless an exception applies, plus ordinary income tax where applicable. Confirm the designation, amount, and account type before funds move.
- Write the tax year on the form or online selection before you submit.
- Keep a confirmation showing amount, account type, and year.
- Check compensation and spousal eligibility before funding a nonworking spouse.
- File or correct the designation before the April deadline passes.
