I've paid an easy account through Snap-on credit can I do that that from my taxes it's used only for tools in toolbox for work

The payments on the credit account are not, themselves, tax deductible, but the cost of the tools purchased probably are. 

If you are self-employed or an independent contractor (your pay gets reported on a Form 1099-MISC rather than a W-2) then you can certainly deduct the cost of tools and supplies as a business expense.

• Under the Business tab, select Business expenses > Other common business expenses;
• Scroll down to Supplies;
• This will take you to a screen where you may list categories of supplies (i.e., hand tools, supplies, etc.) and the associated amounts.

If you are an employee (pay is reported on Form W-2), you can claim those tools and supplies as an unreimbursed employee expense on Schedule A. This will only be a benefit to you if you itemize your deductions rather than taking the standard deduction. Further, unreimbursed employee expenses are subject to the 2% rule, meaning that you can only deduct the portion of the expense that exceeds 2% of your Adjusted Gross income.
