You realize expenses go up when you add people, right? If this is news to you please tell me you don’t work in public policy. |
Those 3 families in that former SFH will not be paying the level of income taxes being paid by that former single family in that former SFH. Those 3 families are more likely to be among the families that pay no or almost no income taxes. 3 families paying taxes at very low marginal rates will not offset the taxes paid by the single family at a higher marginal rate. Suggesting that a single family owning a SFH is likely to be in a higher income tax bracket than 3 families living in a triplex seems obvious. Moreover, those 3 families generally will require more services than that former single family. Assuming on average 2 kids per family, you are now educating 6 kids rather than 2 kids. Note property taxes fund the schools, so that "roughly" the same property taxes from all 3 families now must pay for 6 kids. It will not. Again, you are switching a net tax plus to a net tax drain. Of course, there will be exceptions, but those are the basic realities. |
You know what they say about assuming. |
The triplex units will have significantly more student generation on average. So it will be a net negative for tax revenue in comparison to a SFH. A triplex will generate around 1.386 students on average while a SFH generates around .562 students on average. The county share of school spending for each student is around $13,300. So a triplex costs the county $18,434 a year for schools. A SFH costs the county $7,475 a year for schools. The average property tax revenue from a SFH covers this school spending, but the average triplex does not. |
Why do you assume the bolded? |
What's your source for this? How much tax revenue will a triplex generate? |
You can work backwards to see what the average assessed value of a triplex would need to be cover the pro rata share of school expenditures. https://www.montgomerycountymd.gov/Finance/Resources/Files/data/propertytaxrate/2024/RealProperty.pdf The breakdown of property tax assessments indicates that property tax rate for county level assessments are approximately 1% of the assessed value. So under the most optimistic assumption that 100% of county level property revenue goes to school funding, the assessed value of the triplex would need to be 1.84M+ to cover school expenses. However, the number are actually less favorable than this because much of the property tax assessment is linked funding for specific local government services. The actual assessment that is available for school funding is only 0.717%. This means a triplex needs to have an assessed value of 2.57M+ to cover school expenses (assuming that all general fund+MCPS property tax revenue) is allocated to schools. |
Okay, that's how much tax revenue you say the triplex would need to bring in to break even. So how much would it actually bring in? |
I support building triplex/quadplex units within walking distance of the metro, but I think that allowing them everywhere in the county by right is not a smart policy decision. It will have a negative impact on county finances, risks worsening school overcrowding and creating traffic issues. It would be more prudent to try a targeted zoning reform first, before implementing significant county-wide changes through a ZTA. |
Had they come out and said something like that we’d be in a very different place. Instead, they got Thrive pushed through, now the corridor plans (with associated zoning changes), the upzoning mess being discussed here, and separately the change in parking requirements near metro and other “mass transit” (you know, the bus). The last planning board (that put this all in motion) resigned in disgrace and the current board picked right up where they left off. It’s all very comforting, isn’t it? Makes you really trust the council members to do the right thing. |
Who is "they" and who are "we" in your post? And, actually, who is "you"? |
In 2021, at the Federal level, top 1% paid 45% of all Federal income taxes, top 10% paid 75%, top 50% paid 97%, and bottom 50% paid 3%. Maryland may be different but only by degree. MC may be different but only by degree. In essence, income tax revenues, whether Federal, state, or county, are heavily reliant on upper income taxpayers. CA and NY are well aware of this fact. Being generous, we can estimate that 30-40% of MC residents pay almost no income taxes, whether Federal, state, or county. So, 3 families living in that triplex are far more likely to be among that 30-40% than that single family. Reality, it is. https://taxfoundation.org/data/all/federal/latest-federal-income-tax-data-2024/#:~:text=The%20top%201%20percent%20of%20taxpayers%20paid%20a,paid%20rose%20from%2042.3%20percent%20to%2045.8%20percent. |
There are 3 related concepts. First, families living in duplexes, triplexes, or quadplexes will generally be in lower income tax brackets than the single family living in the SFH. A sizable portion of MC residents pay none or few income taxes. A huge portion of the income taxes are paid by basically the top 25%. Second, comparing total property tax revenues between a SFH ad a duplex/triplex/quadplex needs to be offset the larger number of residents in that former SFH. Third, the aggregate income and property taxes paid by a family must support more than simply the school budget. The end result is that families living in these units will likely cost the MC money. Not every family of course, but I suggest most. |
What’s the answer then? How much tax revenue will a triplex bring in, relative to a SFH? You’re the one saying that the gap between revenues and service costs for the triplex will be even higher than for the SFH. Can you show your work? |
Very simple. Top 25% pay 90% of all Federal income taxes, while bottom 50% pay almost no Federal income taxes. See Tax Foundation. Maryland and MC presumably are roughly similar. We can reasonably assume that SFH owners are more likely to be among that top 25%, and that residents in duplexes/etc are more likely to be among the bottom 50%. The next step is to figure out whether the aggregate property taxes from a duplex/etc offset the costs of servicing the residents. As a PP shows, those aggregate property taxes will not even offset the costs of educating the students living in that duplex/etc. Since we estimate that these residents in duplexes/etc pay few income taxes, and since we estimate that the property taxes paid by them do not even cover the school expenditures, they generally will be net tax losses to MC. Not everyone of course. And, of course, if these residents need services, they should get them. But upzoning means replacing net tax benefit residents with net tax loss residents, which is not a good business model. MC needs more top 25% residents, in order to fund the services being provided to all residents. |
