Mississippi gambling tax calculator
Mississippi allows gambling losses only as an itemized deduction on the state return, whether or not you itemize federally. Take its standard deduction and it taxes your gross winnings. Whether only 90 percent of your losses count from 2026 is not settled. Winnings its own casinos report on Form W-2G are outside this, under a separate 3 percent final tax.

How Mississippi treats gambling losses
Mississippi does not tie the deduction to your federal itemizing choice. You can itemize on the Mississippi return even if you take the federal standard deduction, but the losses count only if you do, in place of Mississippi's standard deduction.
This does not reach Mississippi’s own casinos. Winnings a casino there reports on Form W-2G are outside the income tax, under a final tax of 3 percent withheld at the casino, and losses there are not deductible at all. The examples below follow the ordinary return, which is where winnings from anywhere else go.
The two examples below are the same numbers the calculator uses, worked at Mississippi rates.
Two examples, worked at 2026 Mississippi rates
A single filer with $60,000 of other income who takes the standard deduction on everything except gambling losses.
A losing year
You win $50,000 and lose $52,000, so you finish down $2,000.
- Federal
- $3,596
- Mississippi
- $220
- Total
- $3,816
You finished the year down and still owe tax.
Federally you itemize, so your losses offset your winnings, but the 2026 rule caps that deduction at 90 percent and leaves $3,200 taxable. Mississippi lets you deduct gambling losses from outside Mississippi as an itemized deduction on the state return, whether or not you itemize federally. Your Mississippi income, after the larger of the standard deduction and your itemized deductions, and your $6,000 personal exemption, goes from $51,700 without the win to $57,200 with it. The extra $5,500 is taxed at 4 percent, which comes to $220.
A winning year
You win $50,000 and lose $10,000, so you finish up $40,000.
- Federal
- $10,350
- Mississippi
- $1,732
- Total
- $12,082
Federally you take the $16,100 standard deduction, which is worth more than itemizing, so your gambling losses do not reduce your federal tax at all. Mississippi lets you deduct gambling losses from outside Mississippi as an itemized deduction on the state return, whether or not you itemize federally. Your Mississippi income, after the larger of the standard deduction and your itemized deductions, and your $6,000 personal exemption, goes from $51,700 without the win to $95,000 with it. The extra $43,300 is taxed at 4 percent, which comes to $1,732.
