Is it true that when you buy a home you get taxed less on your paycheck?

Currently you are allowed to write off the mortgage interest on your home. This will reduce the amount of taxes you owe. You can reduce the amount of withholding from your paycheck to offset that or you can get a refund after filing your taxes in April.

I am not sure of the exact figure but I think it is around 5,500 for the standard deduction. If you exceed that figure with the amount of interest and other deductions then you can file the 1040 form and itemize your deductions. If you knew what you would save in taxes you could increase your number of dependents and have less taken out of each paycheck. However, if you estimate incorrectly and you end up owing the IRS a fair chunk then they will make you pay a penalty.

Your realtor will tell you there is a gold mine in the back yard to get you to buy. Your tax situation varies. decreasing your withholding can be done without buying a house and the result is the same. Not enough withheld you owe come April. Talk to a CPA and don't trust your realtor

That is not true, you can write off the mortgage interest on your tax return. Be careful on what you think you hear.

No, but when you file your return you will get a bigger refund.
