Do Freelancers Owe State Quarterly Taxes? (50-State Guide)

Updated May 6, 2026 2026 · 10 min read

Most freelancers learn about federal quarterly estimated taxes the hard way. Then they get a second surprise the following year: their state wants quarterlies too. The rules are not the same across all 50 states — different thresholds, different due dates, different penalty rates — but the headline is simple. If your state has an income tax, and you owe more than a small threshold at year end, you are required to pay it in quarterly installments throughout the year. This guide tells you which states require it, what the thresholds are, when payments are due, and what happens if you skip them.

The 9 states with no income tax (and the 1 oddball)

Nine states do not tax wage or self-employment income at all. If you live in one, you do not owe state quarterlies. You still owe federal quarterlies — those are separate — but the state side of the bill is zero.

• Alaska
• Florida
• Nevada
• New Hampshire (taxes interest and dividends only — wage and freelance income are exempt; the interest/dividend tax is being fully repealed effective TY 2025 (HB 2))
• South Dakota
• Tennessee
• Texas
• Washington (no income tax, but a 7% capital gains tax on gains over $250k applies to a small subset of high earners)
• Wyoming

If you live in any other state, keep reading. You probably owe state quarterlies.

Sample state thresholds — when state quarterlies kick in

Each income-tax state sets its own minimum-tax threshold for triggering the quarterly requirement. Below that threshold, you can simply pay the bill once a year on April 15. Above it, the state expects four payments throughout the year.

Almost any full-time freelancer with state-sourced income will clear these thresholds. A part-time side hustler making a few thousand a year may stay under and avoid quarterlies.

For your exact state's rules, visit the state-specific calculator — every state page lists its threshold, due dates, payment portal link, and an estimator that combines federal, state, and SE tax in one number.

State due dates — they're not all federal-aligned

The federal quarterly due dates for tax year 2026 are April 15, June 15, September 15, and January 15, 2027. Most states piggyback on these exact dates. A few do not.

The notable outliers:

• California (FTB). California uses a famously front-loaded schedule. The four installments are not 25% / 25% / 25% / 25% — they are 30% / 40% / 0% / 30%. Q1 (April 15) is 30% of estimated annual tax, Q2 (June 15) is 40%, Q3 has no payment, and Q4 (January 15) is the remaining 30%. This catches many newcomers off guard.
• New York (NYS DTF). Same dates as federal, but NYC residents must also pay NYC personal income tax — bundled with the state payment, not a separate filing.
• Iowa. Q4 due April 30 (not January 15).
• Hawaii. Q1 April 20, Q2 June 20, Q3 September 20, Q4 January 20. All shifted by 5 days.
• Indiana, Delaware. Both align with federal but with state-specific forms (IT-2210 for Indiana, 200-ES for Delaware).

Most other states simply mirror April 15 / June 15 / September 15 / January 15. When in doubt, check your state's revenue department site or your state's page on this site.

How much you actually owe to your state

State income tax for freelancers is calculated the same way it is for W-2 workers, with one important addition: you owe state tax on your net self-employment income (gross minus business expenses), not your gross. Most states accept the same business deductions you take federally on Schedule C.

What states do not charge: a state version of self-employment tax. SE tax (15.3%) is federal only. Your state simply taxes the income; there is no state SE tax on top.

Rough state quarterly math:

1. Project your net SE income for the year.
2. Multiply by your state's marginal rate (or use the brackets if your state is progressive).
3. Subtract any state-level deductions and credits (standard deduction, dependent credits, etc.).
4. Divide by 4. Pay that each quarter.

For a freelancer netting $80,000 in California, the state tax works out to roughly $4,200 — about $1,050 per quarter (under California's normal proportional model; under the actual 30/40/0/30 model, the Q1 and Q2 payments are larger). Run the Quarterly1099 calculator for your state and income to get the exact number.

What happens if you skip state quarterlies

States charge their own underpayment penalty, separate from the IRS. The structure is similar — interest accrues per day on the missed amount until you catch up — but the rates and rules vary.

• California. Underpayment penalty mirrors federal Section 6621 (~6-7% annualized in 2026), set by FTB. Form FTB 5805 calculates it.
• New York. Roughly 7.5% annualized. Form IT-2105.9.
• Illinois. ~6-7% annualized in 2026. Form IL-2210.
• Most other states. Penalty rates of 5-10% annualized are typical. Many states publish the rate quarterly.

The penalty is usually small in dollar terms — similar magnitude to the federal penalty — but it stacks on top of the federal one. A freelancer who skips both federal and state Q2 by 90 days on a $3,000 federal / $800 state miss would owe roughly $59 federal plus $16 state in penalties. Annoying, not catastrophic.

Most states also offer the same kinds of safe harbors as the IRS — pay 100% of last year's state tax (or 110% for high earners in some states) and the penalty is waived even if you missed individual quarters. California, New York, and Illinois all use this structure.

Special cases — multi-state freelancers, residents abroad, and city tax

A few situations complicate the basic state-quarterlies story.

• Living in one state, clients in another. Generally you pay tax to the state where you live (your state of residence), not where your client is based. Remote freelancers serving out-of-state clients almost always file only in their home state.
• Moving mid-year. You file part-year resident returns in both states, dividing income by the days you lived in each. Quarterlies should follow the same split — pay the new state starting the quarter you moved.
• Working from a state where you do not live. If you physically work in a state for a meaningful portion of the year (more than ~30 days, varies by state), you may owe nonresident state tax there. Common for traveling freelancers.
• City tax. A few cities tax income on top of state — NYC (~3.9% top), Yonkers, Philadelphia (3.75%), most Ohio cities (~2-3%), Detroit (2.4%), some Maryland counties. City tax is usually paid through the same state quarterly filing, not a separate one.
• S corp owners. If you elected S corp status, you pay state tax on both your W-2 wages from the business and your K-1 distributions. Quarterlies cover the K-1 portion.

The simple system

Three steps that work for everyone:

1. Use one calculator that combines federal + state + SE. Don't try to estimate state tax separately — you'll forget. The Quarterly1099 calculator outputs a single quarterly number for federal and state combined. Save that percentage off every check.
2. Pay state and federal on the same day. Calendar a single "quarterly tax day" reminder for each due date. Pay federal via IRS Direct Pay, then state via your state's portal (FTB Web Pay for California, NYS Online Services for New York, etc.). Twenty minutes total per quarter.
3. Use last year's state tax as your safe-harbor target. Just like federal, paying 100% of last year's state tax (split into 4) almost always avoids the state penalty, even if your income changes.

FAQs

I live in Texas. Do I owe any state quarterlies?
No. Texas has no state income tax, so no state quarterly payments are required. You still owe federal quarterlies if you expect to owe more than $1,000 federal at year end.

I'm a freelancer in California. Why are my Q1 and Q2 payments so big?
California's FTB uses a 30% / 40% / 0% / 30% installment schedule, not the federal 25% / 25% / 25% / 25%. Q1 (April 15) is 30% of estimated annual state tax and Q2 (June 15) is 40% — together that's 70% of the annual bill front-loaded.

Can I just pay state once a year on April 15?
Only if your projected state tax bill is below the threshold (typically a few hundred dollars). Above the threshold, the state will assess an underpayment penalty just like the IRS does.

Do I need to file a state estimated tax form, or just pay?
Most states accept payment online without a separate form (CA Web Pay, NY Online Services, IL MyTax, etc.). The form (CA 540-ES, NY IT-2105) is a voucher used for mailed payments. If you pay online, the form is not required.

I moved from California to Texas mid-year. Do I owe California quarterlies for the rest of the year?
Only on income earned while you were a California resident (and any continuing California-source income). Once you've established Texas residency, future income is Texas-only — no California state tax. File a part-year resident return in California for the year of the move.
