Buying a Home
Your tax basis is generally what you paid for the home, plus certain additional costs. Your basis matters because it reduces taxable gain when you eventually sell. These generally include the purchase price and associated fees that are associated with purchasing a home. You will get an American Land Title Association (ALTA) statement that lists the purchase price and all of these fees.
Real estate taxes, while on the ALTA statement, do not increase or decrease the basis of your home. More on this down below.
After purchase, your basis increases by the cost of capital improvements — improvements that add value, prolong the life of the home, or adapt it to new uses.
Examples include:
- Room additions
- Kitchen or bathroom remodels
- New roof
- HVAC replacement
- Finished basement
- New windows
- Driveway replacement
Routine maintenance does not increase basis (painting, minor repairs, lawn care, etc.).
Keeping detailed records of improvements is critical. Many homeowners miss out on thousands of dollars in basis adjustments simply because they do not retain documentation.
Real Estate Taxes When Buying a Home
Illinois property taxes are paid in arrears. What does that mean? The taxes are paid in the year after you had the benefit of living in the home. This creates confusion at closing.
Deductibility of Property Taxes
For federal purposes, you may deduct property taxes only for the period you actually own the home, regardless of how the closing statement allocates them.
If the seller gives you a credit at closing for property taxes attributable to the period they owned the home:
- The seller deducts their portion.
- You deduct only the portion attributable to the time you own the property.
Even if you write the check at closing, you cannot deduct taxes that relate to the seller’s ownership period.
Property taxes are claimed as an itemized deduction on Schedule A and are subject to the $40,000 SALT limitation under current federal law.
Tax Implications of Selling a Home
Homeowner’s Exclusion of Gain
Under Internal Revenue Code Section 121, if you owned the home, occupied it as your primary residence at least 2 of the last 5 years, then you are able to exclude up to $250,000 of gain for those filing as Single or up to $500,000 of gain for those filing as Married Filing Jointly.
If your gain exceeds the exclusion, the excess is subject to capital gains tax.
Selling Expenses
Selling expenses reduce the amount realized on the sale, which directly lowers taxable gain. These will be found on the ALTA statement when you sell the home. Common expenses included are commissions, attorney fees, and other associated fees
Real Estate Taxes in the Year of Sale
Just like at purchase, property taxes must be allocated between buyer and seller based on ownership period. Again, deductions are subject to the SALT limitation.
Why Proper Planning Matters
Many homeowners:
- Fail to track capital improvements
- Misunderstand property tax allocations at closing
- Overlook selling costs that reduce taxable gain
- Miss opportunities to fully utilize the home sale exclusion
A properly calculated basis can significantly reduce or eliminate capital gains tax exposure.
If you are buying or selling a home in Illinois and would like guidance specific to your situation, proactive tax planning can prevent surprises and maximize your after-tax outcome.
What and When to Communicate with Your CPA
Let your CPA know when you purchase, improve, or sell a home when it’s happening. They can help give you an idea of any tax implications the transaction may have before the sale goes through and it may be too late.
Home Purchase and Improvements
You can let them know when you are planning on purchasing a home or after you make the purchase. There is usually a minimal tax effect. It can be a good idea to give your CPA a copy of the ALTA statement so it can be ready to go when the time comes to sell your home.
Sale of Home
Talk to your CPA when you are thinking of selling you current home. Any tax planning can be completed so you can be better prepared for what’s to come and if there is the possibility of any capital gains.
