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.
But when it comes to determining whether you have to file a return, the IRS says if you turned 65 on New Year's Day, you are considered to be 65 at the end of the previous tax year. The one-day grace period allows you to use the higher income thresholds to determine whether you must file a tax return.
