Section 8 rent is split between you and the program, and the split depends on your income

You do not pay a fixed amount. Instead, you pay a percentage of your income, and Section 8 pays the difference up to a limit set by your local housing authority. The percentage is usually 30 percent of your adjusted gross income — that is, your total household income minus certain deductions like child care or medical expenses. Section 8 then pays your landlord the rest, up to the fair market rent for your area.

This means your actual rent payment changes when your income changes. If you earn more, you pay more. If you lose income, your payment drops. The program recalculates your share once a year, though you can request an interim adjustment if your income drops significantly.

The fair market rent ceiling varies by county and bedroom size. A one-bedroom in one county might have a fair market rent of $1,200, while the same size unit 30 miles away might be $950. Your housing authority publishes these limits annually, and they determine the maximum the program will pay on your behalf.

Key Takeaways

  • You pay 30 percent of your adjusted gross income toward rent; Section 8 pays the rest up to the fair market rent limit for your area.
  • Fair market rent limits are set by county and bedroom size, and your housing authority publishes them each year.
  • Your rent payment recalculates once yearly when your income is re-examined, or sooner if you report a significant income drop.
  • If your landlord's asking rent exceeds the fair market rent limit, you cannot use Section 8 to cover the gap, and you must pay the overage yourself or find a different unit.

How your income determines what you pay

The calculation starts with your total household income — wages, Social Security, child support, unemployment, pensions, and other regular income sources. From that, your housing authority subtracts allowable deductions. These typically include a dependent deduction (usually $480 per dependent), a disability deduction if you or a household member receives SSI or SSDI, and sometimes child care costs or medical expenses for elderly or disabled household members.

Once deductions are subtracted, you have your adjusted income. Thirty percent of that number is what you pay. If that 30 percent is less than the minimum rent your housing authority sets (usually $25 to $50), you pay the minimum. If it is more than the fair market rent for your unit size, you still only pay up to the fair market rent — Section 8 does not subsidize rent above that ceiling.

Example: Your household income is $24,000 per year. You have one dependent, so your deduction is $480. Your adjusted income is $23,520. Thirty percent of that is $7,056 per year, or $588 per month. If the fair market rent for a two-bedroom in your area is $1,400, Section 8 pays your landlord $812 per month, and you pay $588.

Fair market rent limits and what happens when rent exceeds them

Each housing authority receives a list of fair market rents from the U.S. Department of Housing and Urban Development. These are updated annually and vary by county and number of bedrooms. A two-bedroom in an urban county might have a fair market rent of $1,600, while a two-bedroom in a rural county might be $900.

Your housing authority uses these limits to determine the maximum it will pay on your behalf. If you find a unit where the landlord is asking $1,800 for a two-bedroom but the fair market rent is $1,600, Section 8 will only pay up to $1,600. You would have to pay the extra $200 yourself each month, on top of your 30 percent share. Many tenants cannot afford this overage, so they look for units within the fair market rent limit.

Some housing authorities allow rent reasonableness exceptions, which means they may approve a unit that exceeds the fair market rent if they determine the rent is reasonable for the neighborhood and unit quality. This is uncommon and requires approval before you sign the lease. Ask your housing authority whether this option exists in your area and what the process is.

Changes to your rent payment when income changes

Your housing authority recalculates your income and your rent payment once per year, usually on your lease anniversary. If your income has increased, your rent payment increases. If it has decreased, your payment decreases. You will receive a notice of the new amount before it takes effect, usually 30 days in advance.

If your income drops significantly during the year — you lose a job, hours are cut, or a household member moves out — you can request an interim adjustment. You will need to provide documentation of the income change, such as a termination letter or recent pay stubs showing reduced hours. The housing authority will review your request and, if approved, adjust your payment when ready rather than waiting for the annual recalculation.

Conversely, if your income increases, you cannot request a decrease before the annual recalculation. You pay the higher amount until the next anniversary, when the new calculation takes effect.

What happens if you cannot afford your share

If your calculated 30 percent share is more than you can pay, you have limited options within the Section 8 program itself. You cannot ask the housing authority to lower your percentage — 30 percent is the standard. You can request an interim adjustment if your income has dropped, but that requires documented proof of the income loss.

Your other option is to move to a less expensive unit. If you find a unit with a lower rent, your 30 percent share will be lower, and Section 8 will pay less as well. You would need to request a lease transfer from your housing authority, which involves finding a new landlord willing to accept Section 8, passing inspection, and signing a new lease.

If you fall behind on your share of the rent, your landlord can begin eviction proceedings. Section 8 pays its portion directly to the landlord, but you are responsible for your portion. Nonpayment of your share is grounds for eviction in most states.

Differences between Section 8 and other housing programs

Public housing (also called low-income housing) uses the same 30 percent income calculation, so your rent works the same way. The difference is that public housing is owned and operated by your local housing authority, while Section 8 units are privately owned and the program subsidizes your rent through a voucher.

Project-based rental information is similar to Section 8 but is tied to a specific building rather than to you. If you move, you lose the subsidy. Section 8 is tenant-based, meaning the subsidy follows you to any approved unit.

Low-income housing tax credit properties set their own rent based on area median income, not on your individual income. You may pay 30 percent of your income or a flat rent set by the property — whichever is lower. These rents are often lower than Section 8 fair market rents but are not subsidized by a voucher.

Frequently Asked Questions

What if my landlord raises the rent after I move in?

Your landlord can raise the rent when your lease renews, but the increase must comply with state and local rent control laws. Section 8 will only pay up to the fair market rent for your area. If the new rent exceeds that limit, you would have to cover the overage yourself or move to a different unit.

Does Section 8 count child support or alimony as income?

Yes, child support and alimony are counted as income for the rent calculation. However, if you are receiving child support that is not being paid regularly, you can request that only the amount actually received be counted. Bring documentation of what you actually receive, not what you are owed.

Can I negotiate a lower rent with my landlord to reduce my Section 8 payment?

You can negotiate any rent you want with your landlord, but Section 8 will still calculate your 30 percent share based on whatever rent you agree to. If you negotiate lower rent, both your payment and Section 8's payment go down. The landlord must agree, and the new rent must still be approved by the housing authority.

What if I get a raise and my rent payment goes up but I cannot afford it?

You cannot request a decrease before your annual recalculation. Your options are to request an interim adjustment if your circumstances change again, or to move to a less expensive unit. Some tenants choose to move rather than accept a higher rent payment after an income increase.

Does the housing authority count my savings or assets as income?

Most housing authorities do not count savings or assets toward the income calculation. They count only regular income — wages, benefits, pensions, and similar sources. However, if your assets generate income (interest, dividends, rental income), that income is counted. Ask your housing authority about their specific asset rules.
