 your total income. If you're married filing jointly and your income is about $123,000 gross or less, you can sell assets that are subject to capital gains without any capital gain tax. Now, if you've owned a property or some stock for over a year, it would be subject to long-term capital gains, again, as long as your income is below that $123,000 joint married. If you're single, that number is about $61,500.
