This year I pay taxes on income earned in 2018 for freelance work I did for a foreign company. According to the IRS, because this was my first year, I didn't have a previous years income for quarterly tax estimates, therefore I didn't need to file quarterly self-employment taxes. They told me over the phone, reading directly from the IRS form.
Do I need additional forms to file this income?
How do I deduct expenses incurred while self-employed?
Any suggestions to how to file effectively?
