I purchased a house last year. Can I claim back any/all the escrow fees?-Title charges/Loan Policy Disclosure Fee/notary fees/Sub-escrow fees etc?

You can deduct mortgage interest, points, and real estate property tax paid at closing. You report those expenses along with other mortgage interest/property taxes paid in the year at
Federal Taxes (or Personal if using Home and Business)

My Home

All other costs paid at closing, including transfer taxes, "stamps", escrow fees, etc., are NOT deductible from current income, instead you add them to the cost basis of your home and you will get the benefit when you sell.

Buying a home is not a guarantee of a big refund.  Your deductions for homeownership combined with your other deductions (if any) must exceed your standard deduction to change your tax due or refund. If you purchased your home late in the year, you do not even have a full year of home ownership deductions.

 Go to Federal> Deductions and Credits> Your Home to enter mortgage interest, property taxes, private mortgage insurance and loan origination fees (“points”) that you paid in 2016.  You should have a 1098 from your mortgage lender that shows this information.

Your closing costs on your new home are not deductible except for prepaid interest, prepaid property tax or loan origination fees.  There are no deductions for appraisal, inspections, settlement fees. etc.

Your down payment is not deductible.

Your homeowners insurance for fire, hazard, flood, etc. is not deductible for your own home.

Home improvements, repairs, maintenance, etc. for your own home are not deductible.
