Do Home Improvements Raise Your Property

Do Home Improvements Raise Your Property gives you a clear, step-by-step way to understand what drives your bill, what to verify on your notice, and what to do if the numbers look off.

Taxes? A common homeowner question is “If I renovate, will my taxes go up?” The short answer: Often, yes – but it depends on what and when. Here’s what to know about home improvements and taxes:

• Major Upgrades Typically Increase Assessed Value: Permanent additions usually raise your

home’s market value, and taxes follow value. For example, adding a bedroom, bathroom, deck or pool is presumed to increase your worth. Kiplinger explicitly advises avoiding extensive “home improvements,” as renovations tend to bump up assessed values. If you add a new wing or finish an attic into livable space, your next assessment will almost certainly be higher.

• Minor Repairs Usually Don’t Trigger Higher Taxes: Small maintenance items – painting, replacing

carpet, fixing a roof or HVAC – generally don’t count as value-increasing in a big way. They’re considered upkeep (and often have depreciation). Unless your locality does continuous reassessments, they’ll only raise taxes by keeping your house in average shape (not necessarily above-average). Of course, if you claimed a deduction or credit for energy-efficient upgrades, those wouldn’t increase taxes at all and can even save money.

• Timing Matters: Some areas reassess only on sale or after major work. If you remodel a year after

the assessor’s valuation date, you might escape any immediate tax increase until the next cycle. In other places, any permitted improvement triggers an automatic reassessment for that year’s taxes. Check your local rules. For instance, if you add a finished basement in January but valuations were already set for that cycle, it might only be added next year. 11

• Capital Improvements vs. Maintenance: Tax officials distinguish “capital improvements” (structural

changes adding value) from repairs. Capital improvements (kitchens, additions, pools) raise your tax basis. Routine maintenance (new roof on old house, repaving driveway) usually doesn’t. Keep receipts and permits for improvements; if you improve for personal enjoyment rather than as an investment, you may not always see a tax jump (but many will adjust valuations anyway).

• Check for Exemptions or Incentives: Ironically, some improvements come with tax breaks. For

example, solar panels, energy-efficient windows or water-saving fixtures might qualify for credits (which can offset any value increase). Some historic districts allow limited restoration without full reassessment. Before you renovate, research if your improvements are even recognized by the assessor.

• Real-World Example: In one case, a Florida couple received a reassessment after what their county

called “substantial improvements,” even though it was their primary residence. They had to pay higher taxes because the new additions were valued in the next assessment. This shows that substantial work can catch up to you. On the flip side, if you live in a capped-taxes state (like Florida’s “Save Our Homes” for primary residences), the state limit might soften the blow of your improvements (though the cap resets if you sell).

• Before and After: If you’re planning a big project, consider checking your assessed value first. Using

ProptaxHelper’s valuation tool before and after an improvement gives you an estimate of how much value you might be adding (and how taxes could rise). If taxes do increase later, you have data to understand the change or even contest an overly high valuation of the improvement.

• Selling Your Home: Note that major improvements do raise your property’s cost basis, which could

lower capital gains tax when you sell (up to the home-sale exclusion limits). But that’s for federal income tax, not your annual property tax. Keep this separate: for property tax, improvements are generally seen as adding value. Bottom line: Yes, many home upgrades can raise your property taxes over time. If the improvement makes buyers willing to pay more for your house, the assessor will use that higher value. However, simple repairs and maintenance typically do not raise taxes. Plan accordingly: if you can delay non-essential high-value upgrades until after an appeal or tax cap period, you might save money. And always verify your new assessment after big projects – if the assessor overvalued the improvement, you have the right to appeal

the new assessment just like any other. For specific guidance, ProptaxHelper has a Q&A on improvements and reassessment. Use our tools to project how much your assessed value (and tax bill) could climb after renovations. That way, you can make improvements confidently – knowing what to expect and budgeting for any tax increase.
