Connecticut Gambling Taxes 2026: Winnings, Losses, W-2G and Withholding
The first decision is the gambling year. A 2025 return filed during 2026 uses the prior federal loss rule, while 2026 gambling activity uses the new 90% federal loss limit. Connecticut separately allows no personal gambling-loss deduction.
Form W-2G and tax withholding do not calculate the final return. Filing status, total income, residency, itemization, records, estimated payments and other tax items remain controlling.
Federal itemized deduction remained capped by gambling winnings.
The itemized deduction is the lesser of 90% of losses or winnings.
Connecticut continues to include winnings without a personal gambling-loss deduction.
Both figures are scope-specific prepayments, not a universal final rate.

How are gambling winnings taxed in Connecticut?
All gambling winnings are federally taxable even if no Form W-2G arrives. Connecticut residents generally include taxable gambling winnings in Connecticut income, and Connecticut does not allow a personal gambling-loss deduction. For 2026 activity, the federal itemized deduction is the lesser of 90% of documented wagering losses or gambling winnings; 2025 returns used the older up-to-100%-of-losses cap for itemizers. Withholding is only a prepayment, not the final tax. Separate the tax year, residency, winnings, losses, forms and withholding before filing. This workflow does not determine one person’s final return.

Connecticut Gambling Taxes in 90 Seconds
| Situation | Current answer | Record or source to check | Practical consequence | Main boundary |
|---|---|---|---|---|
| 2025 gambling activity / return filed in 2026 | All winnings are federally reportable. An itemizer could deduct documented losses up to the lesser of losses or gambling winnings. | 2025 return instructions, W-2G forms, detailed win/loss records and Schedule A. | Do not apply the new 90% rule retroactively to 2025 activity. | The deduction still required itemization and documentation. |
| 2026 gambling activity / return filed in 2027 | The federal itemized loss deduction is the lesser of 90% of documented wagering losses or gambling winnings. | 2026 Form W-2G, Publication 505 and final 2026 return instructions. | A break-even cash result can still leave a federal taxable gambling amount. | The rule applies to 2026 activity, not merely any return prepared during 2026. |
| All federal gambling winnings | Report taxable gambling winnings whether or not the payer issues Form W-2G. | W-2G, operator history, tickets, receipts and personal records. | A reporting threshold does not create a tax-free amount. | The correct figure may require more than an annual operator summary. |
| Connecticut resident treatment | Connecticut residents generally include gambling winnings to the extent included in federal adjusted gross income. | CT-1040, federal return and DRS IP 2011(27) or IP 2015(23). | Connecticut treatment begins with the federal income record. | Filing thresholds, exemptions and the complete return still affect the final calculation. |
| Connecticut personal gambling-loss deduction | None under the current DRS rule. | Current DRS gambling-winnings guidance and enacted-law status. | A federal itemized deduction does not create a Connecticut gambling-loss deduction. | Do not treat a proposed bill as enacted law. |
| Connecticut nonresident — non-lottery gambling | A nonresident’s non-lottery gambling winnings are not subject to Connecticut income tax under current DRS guidance. | Residency record, CT-1040NR/PY instructions and DRS IP 2011(27). | Winning at a Connecticut casino does not by itself create Connecticut income tax for a nonresident. | Reportable Connecticut Lottery winnings use a different rule. |
| Reportable Connecticut Lottery winnings | Residents and nonresidents can be subject to Connecticut tax, with current Connecticut Lottery withholding at 6.99% on reportable winnings. | W-2G, claim record, DRS IP 2015(23) and the current federal reporting rule. | The source of the lottery ticket matters. | CT Lottery’s public threshold wording must be reconciled with current federal guidance. |
| Form W-2G reporting | Form W-2G reports specified winnings and withholding; it does not define every taxable gambling dollar. | Form W-2G, its instructions and the payer’s detailed record. | Reconcile forms with the complete gambling history. | No W-2G does not mean no tax. |
| Federal and Connecticut withholding | Federal 24% and Connecticut 6.99% withholding apply only under specified conditions and are credited on the return. | W-2G boxes 4 and 15, 1042-S where applicable and estimated-payment records. | The return can still show additional tax or a refund. | Withholding is not the final effective rate. |
| Minimum tax record | Keep forms, detailed wagering records, tickets, statements, payments, withholding and a year/residency reconciliation. | The twelve-item record list on this page. | Records support reporting, deductions and source classification. | A record does not guarantee that every claimed deduction will be accepted. |
Current gambling-tax updates checked in 2026
Federal loss deduction changed to 90%
For 2026 activity, the itemized deduction is limited to the lesser of 90% of wagering losses or gambling winnings.
Base information-reporting threshold increased
The 2026 federal base threshold increased to $2,000, with game-specific conditions such as the 300-times-wager test still applying where required.
Connecticut still provides no personal loss deduction
SB 183 proposed a deduction but did not become the current rule. DRS guidance continues to state that personal gambling losses are not deductible.
Federal and Connecticut Tax Formulas
These formulas isolate the gambling component. They do not calculate the complete return.
Documented loss deduction for an itemizer
Allowed loss deduction = min(documented wagering losses, gambling winnings)
Boundary: no itemized deduction without itemizing and adequate records.
New 90% documented-loss limit
Allowed loss deduction = min(0.90 × documented wagering losses, gambling winnings)
Boundary: the formula does not make unverified operator estimates deductible.
Personal gambling-loss deduction
Connecticut gambling-loss deduction = $0
Boundary: this does not mean the final Connecticut tax equals winnings multiplied by 6.99%.
Illustrative remaining balance
Estimated balance = estimated total liability − federal withholding − Connecticut withholding − estimated payments
Boundary: the complete federal and Connecticut returns determine every term in this formula.
Build the Connecticut Gambling-Tax Record in 7 Steps
- 1 Lock the gambling activity year Separate 2025 activity from 2026 activity before applying any federal loss formula or reporting threshold.
- 2 Determine residency for the relevant period Identify Connecticut resident, part-year resident or nonresident status and the date of any residency change.
- 3 Collect forms and complete histories Gather W-2G, 1042-S, Form 5754 records, operator histories, tickets, claim documents and transaction exports.
- 4 Separate winnings, losses and sources Do not merge Connecticut Lottery, other state lotteries, casino, sportsbook, poker and other wagering records without identifying their source.
- 5 Apply the correct federal-year formula Use the prior rule for 2025 activity and the 90% rule for 2026 activity, subject to itemization and documentation.
- 6 Apply the Connecticut residency and lottery rules Keep non-lottery, Connecticut Lottery, out-of-state lottery and part-year-resident treatment separate.
- 7 Reconcile withholding and professional review Match federal and Connecticut withholding plus estimated payments to the forms and seek qualified advice for material, multi-state, group-winner or professional-gambling issues.
Who Connecticut Taxes—and on What
| Scenario | Federal treatment | Connecticut treatment | Controlling record | Main boundary |
|---|---|---|---|---|
| Connecticut resident · casino, sportsbook, poker or online casino | Report taxable winnings; apply the activity-year loss rule if itemizing and documented. | Include winnings to the extent included in federal adjusted gross income; no personal gambling-loss deduction. | Federal return, W-2G, operator history and CT-1040. | An operator’s annual net figure does not automatically replace detailed tax records. |
| Connecticut resident · Connecticut Lottery or iLottery | Report winnings under the correct federal year and form rules. | Winnings included in federal AGI are subject to Connecticut treatment; reportable prizes use Connecticut Lottery withholding. | Original claim record, W-2G, iLottery history and CT-1040. | Withholding does not determine final liability. |
| Connecticut resident · out-of-state non-lottery gambling | Report winnings federally. | Include the winnings; current DRS guidance does not allow a Connecticut credit for tax paid to another state on non-lottery gambling winnings. | Other-state form, federal return, DRS IP 2011(27) and CT-1040. | Do not assume all multi-state income receives a Connecticut credit. |
| Connecticut resident · reportable out-of-state state lottery | Report the state-lottery winnings federally. | An eligible credit for tax paid to the other state can be available under the separate state-lottery rule. | Other-state lottery W-2G, nonresident return and Connecticut Schedule 2. | The exception applies to qualifying state-lottery winnings, not every gambling source. |
| Connecticut nonresident · Connecticut casino or sportsbook | Report taxable winnings federally. | Current DRS guidance excludes non-lottery gambling winnings from Connecticut income tax for a nonresident. | Residency evidence, W-2G and current CT-1040NR/PY guidance. | A Connecticut Lottery prize follows a separate rule. |
| Connecticut nonresident · reportable Connecticut Lottery | Report the prize federally. | Reportable Connecticut Lottery winnings can be Connecticut-taxable and subject to 6.99% state withholding. | W-2G, ticket/claim record and CT-1040NR/PY. | The current federal definition of reportable winnings must control the threshold analysis. |
| Part-year Connecticut resident | Report the full federal-year activity under federal rules. | Non-lottery winnings received during the residency period and special Connecticut Lottery accrual rules can apply. | Residency dates, CT-1040NR/PY, Schedule CT-1040AW and payment dates. | Installment prizes and residency changes require case-specific review. |
| Shared or group winner | The payer can use Form 5754 to prepare a W-2G for each actual winner. | Each winner’s residency and source treatment must be evaluated separately. | Form 5754, ownership agreement, ticket and payer-issued W-2G forms. | One claimant should not automatically report the entire group prize as solely owned. |
| Operator gross-gaming-revenue taxes | Business and operator tax rules are outside this player-return guide. | Operator revenue taxes and state receipts belong to the revenue-statistics owner. | DCP monthly revenue reports and operator statutes. | Operator tax rates do not calculate a player’s income tax. |
W-2G and Withholding: 8 Rules That Change the Answer
| Rule | Current meaning | Record to check | What it does not prove |
|---|---|---|---|
| 1. No W-2G | Taxable gambling winnings still must be reported even when no form is issued. | Detailed operator, ticket, transaction and personal records. | No form does not create tax-free income. |
| 2. W-2G for 2025 activity | Use the form and instructions applicable to the 2025 activity year. | The W-2G revision and return instructions for 2025. | Do not apply the 2026 $2,000 threshold retroactively. |
| 3. 2026 base reporting threshold | Current IRS guidance uses a $2,000 base applicable threshold for 2026, with game-specific tests such as 300 times the wager where required. | 2026 Publication 1099 and current W-2G instructions. | The $2,000 threshold is not a tax-free allowance. |
| 4. Regular federal withholding | Federal 24% withholding can apply when proceeds exceed $5,000 and the wagering category’s conditions are met. | W-2G box 4, wager amount, proceeds and game category. | 24% is not the final federal effective rate. |
| 5. Backup withholding | Backup withholding can apply when a correct taxpayer identification number is not provided and the winnings are reportable. | TIN request, W-2G and payer record. | Backup withholding does not settle the full return. |
| 6. Connecticut non-lottery withholding | A payer transacting in Connecticut generally withholds 6.99% when the payment is federally withheld and paid to a Connecticut resident. | W-2G box 15, residency and payer location. | Not every Connecticut resident gambling payment has automatic state withholding. |
| 7. Connecticut Lottery withholding | The Connecticut Lottery Corporation currently withholds 6.99% from reportable Connecticut Lottery winnings paid to residents and nonresidents. | Claim record, W-2G box 15 and DRS guidance. | 6.99% is not automatically the winner’s final Connecticut liability. |
| 8. Current source conflict | CT Lottery’s public page still states a $600 federal reporting threshold, while current 2026 IRS guidance states a $2,000 threshold. | Current IRS Publication 1099, W-2G instructions and claim-date guidance. | The older $600 figure should not be treated as the controlling 2026 federal rule without updated authority. |

Five Connecticut Gambling-Tax Examples
2025 activity: $10,000 of winnings and $10,000 of documented losses
Federal: an itemizer could generally deduct up to $10,000, capped by the winnings, under the prior rule.
Connecticut: the $10,000 of winnings remains part of the Connecticut income calculation without a personal gambling-loss deduction.
Boundary: this does not calculate the complete federal or Connecticut return.
2026 activity: $10,000 of winnings and $10,000 of documented losses
Federal: the maximum itemized gambling-loss deduction is $9,000 under the 90% rule.
Connecticut: Connecticut still provides no personal gambling-loss deduction.
Boundary: a break-even cash result can therefore leave a federal gambling amount and a larger Connecticut winnings amount in the respective calculations.
A New York resident wins $10,000 at a Connecticut casino
Federal: the winnings remain federally reportable.
Connecticut: current DRS guidance does not treat a nonresident’s non-lottery gambling winnings as Connecticut-taxable income.
Boundary: a reportable Connecticut Lottery prize would use the separate lottery rule.
A user receives no W-2G and had no withholding
Correct conclusion: the reporting threshold and withholding rules do not remove the federal reporting obligation for taxable gambling winnings.
Record owner: detailed operator histories, tickets, transactions and personal records.
Boundary: an annual net statement may not by itself provide the complete return figure.
A group shares one lottery ticket or wager
Correct route: provide Form 5754 to the payer so separate W-2G forms can identify the actual winners where applicable.
Record owner: the original ticket, ownership agreement, Form 5754 and payer-issued forms.
Boundary: this page does not determine ownership when the group’s facts or agreement are disputed.

Stop Signals When Tax Pressure Is Driving Gambling
- You are placing more wagers to create losses for a deduction.Additional losses are real financial losses, may not be federally deductible in full and are not deductible for Connecticut personal income tax.
- You are trying to win the estimated tax amount.Stop the session and address the payment or professional-advice route directly.
- You are considering canceling a withdrawal to keep gambling.Preserve the withdrawal and the tax record rather than creating new exposure.
- You are borrowing, using credit or missing bills because of tax pressure.Do not use gambling as a tax-payment plan.
- You are hiding W-2G forms, account histories or losses.Preserve accurate records and use a qualified tax professional when the filing is material or complex.
- A supposed tax agent asks for payment, credentials or identity documents through an unverified channel.Stop and verify the recipient through the official IRS, DRS, lottery or operator route.
- Tax shock is causing urgency, secrecy, stress or loss chasing.Call 1-888-789-7777 or use CCPG chat before gambling again.
These are gambling-harm interruption signals, not tax, financial or clinical diagnoses.
