If you are coming to Smith Mountain Lake from Washington, the Northeast, or one of the higher-tax metros most of my buyers call home, the property-tax number here will look like a typo. As of the 2025–27 tax years, the three counties that share the lake charge between 41 and 56 cents per $100 of assessed value — Bedford at $0.41, Franklin at $0.47, Pittsylvania at $0.56. On a million-dollar lake home, that is real-money territory measured in the low thousands per year, not the five-figure bills some buyers are escaping. Always confirm the current rate on the county’s own site before you budget, because these numbers do move — Franklin just raised its rate this year — but the headline holds: the tax climate here is genuinely gentle.
Which county am I even in?
The lake spills across three of them — Bedford, Franklin, and Pittsylvania — and the county line does not care about your cove. Two docks on opposite shores can sit in different counties, on different rates, under different rules. So “what are the taxes at Smith Mountain Lake” has three answers, and the one that matters is the one attached to the specific parcel you are considering. It is one of the quieter reasons which part of the lake you choose has consequences beyond the view.
The rates, as they stand
Real estate here is taxed on assessed value, at the county’s rate per $100. As of the current fiscal years: Bedford County $0.41, Franklin County $0.47 (raised from $0.43 in 2026), and Pittsylvania County $0.56 per $100. Most of the lake’s populated shoreline sits in Bedford and Franklin, the two lower rates. There is no separate “lake tax” layered on top — waterfront is taxed as real estate like anything else, on its assessed value. Confirm the live figure with the county before you rely on it: Bedford, Franklin, Pittsylvania.
What actually moves your bill
Two levers: the rate and the assessment. The rate is set by the county and revisited periodically — Franklin’s four-cent bump this year is a normal example of counties adjusting to keep up with costs. The assessment is the county’s opinion of what your property is worth, updated on a reassessment cycle. On the lake, that second number is the one that tends to climb, because waterfront values here have been durable. A gentle rate applied to a healthy assessment is still a gentle bill — but it is the assessment, not the rate, that will do most of the moving over the years you own.
Straight answers
Are property taxes high at Smith Mountain Lake?
No — by the standards of the metros most out-of-state buyers come from, they are low. The three lake counties run from $0.41 to $0.56 per $100 of assessed value. For many of my buyers, the annual tax on a lake home is a fraction of what they were paying up north.
Which county has the lowest rate?
Of the three, Bedford is lowest at $0.41, with Franklin close behind. Most of the lake’s developed shoreline sits in those two. Pittsylvania is higher but holds comparatively little SML waterfront.
Is there a special tax for lakefront property?
No separate lake or waterfront tax. Your dock and shoreline are taxed as part of the real estate’s assessed value, at the ordinary county rate.
Will my taxes jump after I buy?
Your bill can change two ways: a county rate change, or a reassessment of your property’s value. On this lake, the reassessment is usually the bigger factor over time, because waterfront values have held up well.
