I owned my condo for 10 yrs. Looking to sell it. I lived there for 18 mo. out of the last 5 yrs. Do I have to pay ALL capital gains tax or can I write off the 18 months?

I know there is capital gains for rentals but can I prorate since I was there 18 months?

@user17533562053 need more information. 

Why did you not live there the other months?  job somewhere else? medical situation? convenience? rented it out? etc.  please explain in detail. 

That sort of detail will explain the outcome.

On the surface, if you only lived there for 18 of the last 60 months and the reason was simply for convenience you lived elsewhere, you are not eligible fort the capital gains exclusion and will pay all the capital gains tax. 

Also include your expected income and the amount of the capital gains in your response. 

Determining capital gains tax can be trickly at the lower end of the income spectrum - it is not necessarily a straight 15%.

See publication 523.

There is a partial exclusion if the reason you are selling before the 2 years is up is due to certain unexpected financial or personal hardships.  But if there is no hardship involved and it was just your free choice of living arrangements, the entire gain is taxable because you don't qualify for the exclusion.
