on $13K of IC income, it is likely you'll owe almost $1800 in self-employment tax + regular income taxes.
the SE tax is about 14.13% times the net IC income (if your wages take you over the Social Security maximum of $147K in 2022
then the 14.13% drops to about 2.68%
for more info look at schedule SE. it's for 2021 so change line 7 to $147,000 for 2022
