I am married, with one child, and the total income is 65.000 do you think we will have to pay taxes

Of course you pay taxes, the issue is, how much did you pay in during the year, So how much was withheld ( the money they took each paycheck)

Did you both work ?

You qualify for the $1,000 Child Tax Credit, so a refund is probable.

Your income is more than the filing requirements so you MUST file your tax return.
If you are self employed, you will also pay SE tax.
