Professional gambler tax calculator

If gambling is your trade or business, you file on Schedule C — but from tax year 2026 your business expenses are swept into the 90% wagering-loss limit, not deducted separately. Enter your totals to estimate net profit and self-employment tax.

Enter the year's totals
Combined losses + expenses (the figure the limit applies to)$290,000
Deductible (90% limit, capped at winnings)$261,000
Net profit or loss (Schedule C)$39,000
Estimated self-employment tax$5,511

An estimate only. Business expenses are combined with wagering losses under the 90% limit for tax year 2026 and later. The self-employment tax estimate does not apply the Social Security wage-base cap and will overstate for filers with other earned income. Not tax advice — a licensed CPA should review before filing.
