<prompt> Human: Last year I made about 23k from freelance work with several different businesses payments received via check. Nobody has provided me any forms for tax purposes. How do I go about filing taxes for this income? Will I end up owing an insane amount to the IRS? Im pretty terrified to be honest.  <response>: If you did not make quarterly estimated payments, then yes, youll owe a fair bit. If you are still self-employed you should get on that, as Q1 payments are due 418.For last year was 23k your entire income? If so youd owe about 3500 SE taxes plus another 1450 federal taxes. And then whatever state taxes you might have.If you had other income such that this 23k falls in a high tax bracket then your federal taxes will be based on your marginal tax rates.
