The answer to whether closing costs are tax deductible — or mortgage interest and property taxes for that matter — is, maddeningly, “It depends.”
Basically, you’ll want to itemize if you have deductions totaling more than the standard deduction, which is $12,200 for single people and $24,400 for married couples filing jointly. Every taxpayer gets this deduction, homeowner or not. And most people take it because their actual itemized deductions are less than the standard amount.
The one-time home purchase costs that are tax deductible as closing costs are real estate taxes charged to you when you closed, mortgage interest paid when you settled, and some loan origination fees (a.k.a. points) applicable to a mortgage of $750,000 or less.
