Frequently asked questions
Who needs to pay estimated taxes?
Generally anyone who expects to owe $1,000 or more in tax and doesn't have enough withheld — commonly self-employed individuals, freelancers, and those with significant investment income.
When are estimated tax payments due?
Typically in four installments during the year — mid-April, mid-June, mid-September, and mid-January of the following year — check current IRS due dates each year.
Can I pay estimated taxes online instead of mailing a voucher?
Yes — the IRS offers electronic payment options (like IRS Direct Pay) that don't require mailing a paper voucher.
