I do not have the ability to pay the entire amount of capital gains tax in one year may I spread it out over two years?

Remember that you can add any capital improvements made to your home’s cost basis. But, yes, you would have to pay any capital gain (usually taxed at 15%) and can’t spread the payment over 2 years. Your purchase of another home is not relevant. 

@susan_ady-hotmai - how did you calculate the $48,000?

should be what sold the house for LESS the selling expenses (don't forget the commission) LESS what you purchased the house for originally LESS whatever you spent on improvements during your ownership of the home.

If you cannot pay the tax bill in full you can pay in installments but you cannot split reporting the sale onto more than one tax year returns.
