Hi and welcome to our site!
That will affect you ONLY if you are started social security benefits
before the full retirement age.
As you do not know your earning - you woudl not be able to know what amount must be paid back to SSA.
So the best we may do - to make estimation and that estimation will be corrected later as you will know better your situation.
You can get Social Security retirement benefits and work at the same time.
SSA uses the following earnings limits to reduce your benefits: If you are under full retirement age for the entire year, we deduct $1 from your benefit payments for every $2 you earn above the annual limit.
For 2015 that limit is $15,720.
For 2016 that limit is not yet set. Most likely - it will be a little higher.
Please be aware that NET earnings must be considered. That will be after deducting all qualified business expenses
So - we woudl not only need to estimate your gross pay - but also your deductible
If you feel that your earnings will be much higher that the limit - it might be better to stop your social security benefits and apply again later - that will allow larger benefits.
Let me know if you need help with calculations - but we still need to make some assumptions regarding your income.
