TaxOnCryptoQuarterly Estimated Taxes for Crypto Income
On this page
If you earn crypto without tax withheld, the IRS expects estimated payments four times a year: April 15, June 15 and September 15, 2026, and January 15, 2027. You generally avoid the underpayment penalty if you pay at least 90% of this year's tax or 100% of last year's, or 110% if your adjusted gross income was over $150,000. Canada uses instalments due March 15, June 15, September 15 and December 15.
The single most common painful surprise for crypto freelancers is the underpayment penalty. You did nothing dishonest — you just did not know the US tax system expects to be paid four times a year, not once. Here is how quarterly estimated taxes work and how to stay out of trouble.
Why quarterly payments exist
Employees have tax withheld from every paycheck automatically. Freelancers and crypto earners do not. To keep the system “pay as you go,” the IRS requires estimated tax payments from people whose income is not withheld.
The four 2026 deadlines
- April 15, 2026 — for income earned January–March
- June 15, 2026 — for income earned April–May
- September 15, 2026 — for income earned June–August
- January 15, 2027 — for income earned September–December
The periods are uneven on purpose — note that the second “quarter” is only two months.
How much should you pay?
A safe approach for most freelancers: estimate your total tax for the year (income tax + 15.3% self-employment tax + state tax), then pay one quarter of it on each date. The calculator on the home page does this math for you and shows a per-quarter figure directly.
The penalty trap
The underpayment penalty is essentially interest on the tax you should have paid earlier. It is not enormous, but it is entirely avoidable and it compounds. Worse, many freelancers do not discover it until they file — by which point it is too late to fix that year.
A simple system that works
- Open a separate “tax” savings account.
- Every time a crypto payment arrives, immediately move 25–30% into it.
- On each deadline, pay your estimate from that account using IRS Direct Pay.
- Never touch that account for anything else.
This converts a stressful annual scramble into four boring transfers.
Canada note
Canada has a similar instalment system for people who owe more than a threshold in tax. The CRA sends instalment reminders, but crypto freelancers should plan for it the same way: set money aside as income arrives.
Frequently asked questions
Do I have to pay quarterly tax on crypto gains?
If you expect to owe $1,000 or more for the year after withholding and credits, the IRS expects estimated payments, and that includes tax on crypto gains and income.
What happens if I miss an estimated payment?
The IRS charges an underpayment penalty that works like interest on the amount you paid late, calculated for each quarter. Paying the next quarter on time limits it.
How do I pay quarterly estimated taxes?
Through IRS Direct Pay, your IRS online account or EFTPS, or by mailing a Form 1040-ES voucher.
Does Canada require instalments on crypto income?
If your net tax owing is more than $3,000 ($1,800 in Quebec) this year and in either of the two previous years. The CRA sends reminders with suggested amounts.
