The earnings limit for those like you who have not yet reached the full retirement age is $1,310 per month, or $20 more per month than in 2014. If you exceed this limit, you’ll lose $1 of benefits for each $2 of benefits over the limit.
Gifts in excess of an $12,000-per-donee annual exclusion are subject to gift tax, but the tax may be offset by a gift tax credit.
