“The best thing you can do to keep track and manage your winnings and losses is to download win/loss statements from your sportsbook or casino app. That’s bulletproof documentation and mirrors what the operator would report to the authorities. With that said, I am not a tax expert, and everything on this page is a set of suggestions and links to relevant official sources where you can find more information. If you have concerns or questions, your best bet is to contact a tax professional. This is definitely worth it if you’re dealing with large sums of money.”

Federal Gambling Tax Rules

All sources are referenced with links at the bottom of the page, primarily from governmental websites or accredited sources such as CPAs. As mentioned in the previous section, you can reach out to local or national tax authorities for specific queries, and consult a tax professional when needed.

W-2G Thresholds and Withholding
The IRS treats all gambling winnings as regular income tax, specifically "other income," whether from online slots, sports wagers, or poker. Operators must issue Form W-2G and withhold 24% federal tax if certain thresholds are hit. Please see the breakdown in the table below:
| Game Type | Federal Threshold | Federal Withholding | Connecticut Tax Treatment | Forms Needed |
|---|---|---|---|---|
| Online Slots / Bingo | $1,200+ | 24% (if backup) | Residents: All winnings taxed; non-residents 0% (except CT Lottery, 30% Federal, and 6.99% CT State Tax(6)). | W-2G, CT-1040 |
| Poker | $5,000+ net | 24% (if backup) | Same; deduct losses federally only. | W-2G, CT-1040 |
| Sports Betting | $600+ and ≥300× wager | 24% | Report all wins (residents); non-residents exempt. | W-2G or self-report, CT-1040 |
| Keno | $1,500+ | 24% (if backup) | Residents taxed; non-residents exempt. | W-2G, CT-1040 |
| Table Games | Any amount (self-report) | None | Report manually on CT-1040. | 1040 / Schedule 1, CT-1040 |
Note: Non-cash prizes (e.g., a car or hotel stay) are taxed at fair market value. Bonus cash becomes taxable once it’s withdrawable (after wagering requirements).
Example: If you win $2,000 on DraftKings and no W-2G is issued, you still must report it as income on Form 1040 and CT-1040.
How to Report Gambling Winnings (Federal)
- Gather W-2GForms and Operator Statements: Download your annual win/loss summary from your CT-licensed app (more in Section 5 of this CT tax guide).
- Calculate Total Winnings: Add up all reportable income, including small wins under thresholds.
- Report total winnings on Form 1040, Schedule 1, Line 8b: Label as "gambling winnings" with source (e.g., "DraftKings CT sports betting").
- Report losses (up to winnings) on Schedule A, Line 16: Only if itemizing (see Section 2 of this CT tax guide).
- Keep Detailed Logs: Dates, wager types, locations (or app timestamps), and amounts for audits.
Connecticut State Gambling Tax Rules
Online wagering, whether on slots or sports, is based on your physical location (geofencing tracks this with geofencing technology on all regulated CT online gambling platforms(7)). VPNs are not allowed; using any sort of proxy can result in your account being closed and your balance being withheld.
In other words, if you are within state lines, all your online play is based on the location registered to your device, and ultimately on where you are when you use the apps.
Progressive 3% to 6.99% Tax on All Gambling Winnings (Residents Only)
Connecticut applies progressive income tax rates from 3% to 6.99% on gambling winnings, included in your federal adjusted gross income (AGI)(8)(9).
| Category | What’s Taxed | Notes |
|---|---|---|
| Residents | All gambling income (CT and other states) | Report total on CT-1040 Line 1. No credit for taxes paid to other states. |
| Non-Residents | Only CT Lottery winnings | Must file CT-1040NR/PY if CT Lottery withholding. |
| Part-Year Residents | Winnings during the CT residency period | Apportioned on CT-1040NR/PY. |
“Online gambling winnings are usually considered sourced where you live (for residents) or where you were playing (geofencing confirms Connecticut location), not where the operator’s servers or offices are located.”

Connecticut Lottery Winnings and Tax Withholding
| Prize Range | Federal Withholding | Connecticut Withholding | Forms Issued |
|---|---|---|---|
| Under $600 | None | None | N/A |
| $600–$5,000 | None (reportable if ≥300× wager) | 6.99% (if ≥300× wager) | W-2G (if required) |
| $5,000+ | 24% | 6.99% | W-2G |
“Pooling or group wins? Have each participant complete IRS Form 5754(10) so the lottery can issue separate W-2Gs.”

Deducting Gambling Losses: Federal vs Connecticut
Losses are only deductible up to your total winnings for the year on your federal return, and only if you itemize(11). Connecticut does not allow gambling loss deductions.
Eligibility for Gambling Tax Deductions and Requirements of Proof
- Itemization for the Federal Income Tax: Standard deduction takers get zero loss benefit.
- Understand Net limit: If you won $5,000 but lost $10,000, deduct the maximum $5,000.
- Proof is Mandatory: IRS/DRS demands substantiation. You can’t expect the authorities to simply trust you regarding deductions.
- No itemization in the Connecticut return: No loss deduction allowed, even if itemizing federally.
Acceptable proof:
- Operator Transaction History: For example, download summaries from DraftKings CT, FanDuel CT, Mohegan Sun, or Foxwoods, depending on what brands you use.
- Logbook of Bets and Results: Track each wager, outcome, and timestamp (automated when gambling on the regulated local CT gambling apps).
- ATM Withdrawals Near the Casino: As indirect evidence of session spending.
- Include Canceled Checks and Credit Card Statements for Deposits/Wagers as they show funding sources and amounts.
- Form 5754: For group wins (splits liability per player) if you’re engaged in pooled betting or similarly.
“Important: While deductions are allowed when itemizing federally, Connecticut does not permit any gambling loss deduction on the state return.”

How to Report Gambling Income and Losses
Both the CT DPR and the IRS has dictionaries and explanations to help with abbreviations, terms, and forms; including AGI (Adjust Gross Income).
If you have concerns, contact the IRS or a Connecticut tax professional (see the helpful links section at the beginning of this CT gambling tax guide).
Required Forms Checklist

CT-1040 Filing Walkthrough
- File by April 15*(12) (unless extended): E-file for faster processing.
- Start With Federal AGI: Includes gambling winnings reported on Schedule 1.

- Attach W-2G Forms: Required if claiming CT withholding.
- Non-residents/part-year: Use CT-1040NR/PY; report only CT Lottery or residency-period winnings.
- File Electronically via myconneCT(13) or Trusted Software: DRS automatically imports W-2G data from many licensed CT gambling operators and the CT Lottery.
*Please note that April 15 has been the standard date for recent years; however, this date may change from year to year.
Online Operator Win/Loss Statements
Operators must provide annual win/loss summaries by January 31 each year (for gameplay from the previous year). Each online gambling operator has to provide easy access to Win/Loss statements that you can download on your phone or computer:
| Download Operator Win/Loss Statement | How to Access Tax Statement |
|---|---|
| DraftKings CT | My Account → Tax Info → Win/Loss |
| FanDuel CT | Account → Reports → Tax Documents |
| Mohegan Sun | Profile → Tax Forms → Annual Summary |
| Foxwoods | Rewards Account → Documents → Win/Loss |
| CT Lottery | Request a duplicate W-2G by mail or in person |
“Download digital statements and keep them for audits, especially if you itemize losses federally.”

Record-Keeping Best Practices
Must-have documents when filing gambling taxes in Connecticut:
- W-2G Forms: From operators or the lottery.
- Bank and Transaction Statements: Showing deposits and withdrawals.
- Operator Win/Loss Statements: Annual exports.
- Receipts or Paper Bet Tickets: For physical bets (retail casinos).
- Session Logs: Dates, amounts, and outcomes. Apps like Excel or Google Sheets can help automate this for you.
Digital vs Physical Proof
| Type | Accepted by IRS? | Example |
|---|---|---|
| Digital logs | Yes, if accurate and complete | DraftKings or FanDuel win/loss statements |
| Paper tickets | Yes | Slot or table receipts |
| Screenshots | Conditional | Date-stamped screenshots of wins |
“You don’t have to hoard documents forever, but keep tax records for 3–7 years in case of an audit down the line.”

Common Mistakes and Penalties
Top Mistakes:
- Forgetting Small Wins: The IRS cross-checks W-2Gs; even $100 online slot wins can be flagged.
- Deducting Losses on the CT Return is Not Allowed: This can lead to longer lead times and complications.
- Non-residents Paying CT Tax on Non-lottery Wins: Exempt; overpayment possible.
- Misreporting CT Lottery vs Other Wins: Different rules apply.
- Missing SSN on Large Wins: Triggers 24% backup withholding plus potential penalties.
Penalties:
- Connecticut: interest + underpayment penalties.
- Federal: up to 75% of underreported or fraudulent amounts.
“If you’re dealing with larger sums, say above $10,000, consult a CPA to avoid costly mistakes.”
