When your baby is a little older, you can start adding pumping to your daily routine. While it's not necessary, it's comforting to have a little bit of a stash of milk built up before you return to work. Warning - be sure to read this page on smart use of your freezer stash!
You must file a tax return if your net earnings from self-employment were $400 or more. So consider this: you may be 36 years old, single and make less than $10,000 per year in regular employment income, but if you have a side business that nets you more than $400, you will need to file a federal tax return.
If you are older than 65, you must file if your taxable income is over $11,200. To file as a head of household, you must have at least one dependent and not be married. If you use this filing status, you must file a tax return if you are less then 65 years old and have at least $12,500 in taxable income. If you are older than 65, the threshold increases to $13,950. Married couples can chose to file a joint return or two separate returns.
