Discrepancy in Square Footage

[Paul C.]

I purchased a home ~1 year ago as my primary residence. I was poking around and saw that on my property taxes, my square footage is listed at ~2400sqft. However, I checked my appraisal and they have me at closer to 2800sqft. Does this matter at all and is do I have any opportunity? Trying to think about tax impact and resale impact, but let me know if there is anything else I should be keeping an eye on. Thanks!
