Does grandparent's tax exempt earned income qualify towards "earned income" used to qualify for social security/medicare?
Here's the situation:
1. I am married to my wife, we file taxes jointly.
2. My parents are taking care of our kids (both are under 18 years old) in our house and we are paying them $1350/month
3. According to the Household Employer's Tax Guide (Publication 926 https://www.irs.gov/pub/irs-pdf/p926.pdf page 6), we shouldn't "count wages you pay to [parents] as social security or Medicare wages." - this means I don't have to pay any taxes or file any forms about this money I am paying my parents.
4. If my childcare were not from my a "household employee" (aka my parents), then I would normally file Form 2441 (Childcare and Dependant Care) to get the cost of childcare excluded from my taxable income. However, because my parents qualify for the exemption from social security and medicare wage taxes, I do not qualify for the the childcare and dependent care exemption, so I will not be filing Form 2441.
4. This is where things start to get complicated: my mother doesn't have enough years of earned income on file to qualify for social security, so we are planning to have her list the income I am paying her on her Form 1040 Line 7 this year at "earned income" with the abbreviation "HSH" on the dotted line next to it.
5. She will also fill out a 1099 for miscellaneous income for this income.
MY QUESTION IS: will my mother's earned income from this year and situation described above count towards the years of work needed for her to qualify for social security/medicare EVEN THOUGH I, as her "employer," will not be paying the social security/medicare taxes or even reporting this income?
Bonus: I would love if you could link to the relevant IRS documentation to answer my question.
Thank you!
