If you work in affordable housing, you have probably asked about the difference between LIHTC and Section 8 housing. The two programs sound similar, but they solve the problem from opposite ends.
LIHTC funds developers to build affordable units, so the savings are built into the property itself. Section 8 puts money in the hands of tenants through vouchers they use in the private market.
In other words, one increases the supply of affordable housing while the other makes existing housing more affordable. This guide breaks down how each program works, where they overlap, and what it means for developers, investors, and housing authorities.
LIHTC and Section 8 Housing: What’s the Difference?
The core difference comes down to what gets subsidized. LIHTC subsidizes the building, while Section 8 subsidizes the tenant. That one idea explains almost every other difference between the two programs.
LIHTC is a supply-side subsidy. It lowers the cost to build, so rents stay affordable across the property. Section 8 is a demand-side subsidy. It covers part of a renter’s monthly cost in housing they choose themselves.
Low-Income Housing Tax Credit (LIHTC)
Purpose
The Low-Income Housing Tax Credit (LIHTC) is a federal program built to expand the supply of affordable rental housing. Created by the Tax Reform Act of 1986, it lives under Section 42 of the tax code.
How it works
The government awards tax credits to developers who build or rehab affordable units. Developers sell these credits to equity investors to raise cash, which cuts the debt they carry. Less debt means they can charge lower rents and still make the project work.
Administration
State housing finance agencies hand out the credits through a competitive process. The Internal Revenue Service (IRS) oversees compliance, and credits are claimed over a 10-year window.
Rent and tenants
Rents are capped based on Area Median Income (AMI), not on what each tenant earns. To qualify, households generally need to earn no more than 60% of AMI.
Section 8 Housing
Purpose
Section 8 helps low-income families afford housing in the private market. Instead of building units, it supports renters directly so they can live in homes they choose.
How it works
Eligible households receive a Housing Choice Voucher (HCV). The voucher covers the gap between what the tenant can pay, usually around 30% of adjusted gross income, and the actual rent, up to a set limit.
Administration
Local Public Housing Authorities (PHAs) run the program day to day. They follow federal rules set by the U.S. Department of Housing and Urban Development (HUD).
Rent and tenants
Rent is based on local market rates, but the subsidy is capped by the area’s Fair Market Rent (FMR). Most households qualify by earning no more than 50% of AMI, with priority often given to the lowest earners.
Key Differences Between LIHTC and Section 8 Housing
Once you line them up side by side, the difference between LIHTC and Section 8 housing is easy to see. Here is how the two programs compare across the points that matter most.
| Feature | LIHTC (Section 42) | Section 8 (Vouchers) |
| Who it targets | Developers and investors | Tenants and renters |
| Funding mechanism | Tax credits sold to investors | Direct rental payments to landlords |
| Subsidy type | Property-based, supply-side | Tenant-based, demand-side |
| How rent is set | Capped by Area Median Income (AMI) | About 30% of adjusted gross income |
| Portability | Tied to the building | Follows the tenant |
| Administration | State agencies under the IRS | Local PHAs under HUD |
| Eligibility | Up to 60% of AMI | Up to 50% of AMI |
How LIHTC and Section 8 Work Together
LIHTC and Section 8 are often treated as rivals, but in practice they pair up all the time. A single property can use both, which strengthens affordability for everyone involved.
Here is how the overlap works:
- A renter with a Housing Choice Voucher can live in a LIHTC unit.
- The tenant pays about 30% of income, and the voucher covers the rest.
- The property still meets its Section 42 rent and compliance rules.
This combination shows up most in RAD conversions, where older public housing is recapitalized using LIHTC equity alongside long-term Section 8 contracts. The result is renovated housing that stays affordable for decades.
For developers and housing authorities, layering these programs takes careful structuring, and that is where experienced underwriting makes the difference.
Affordable Housing vs. Section 8 vs. Low-Income Housing
Affordable Housing vs. Section 8 vs. Low-Income Housing
People use these terms as if they mean the same thing, but they do not. Sorting them out helps you understand the difference between affordable housing and Section 8.
Affordable housing is the broad umbrella. It covers any program that keeps rent below market, including LIHTC, Section 8, and public housing.
Low-income housing usually points to units with capped rents tied to income limits, like LIHTC properties. The discount is built into the unit itself.
Section 8 is a specific voucher program. It does not own or build housing. It simply helps renters pay for homes on the private market.
So when someone asks about low income housing vs Section 8, the real distinction is this. Low-income housing is a place, while Section 8 is a payment that helps you afford a place.

Frequently Asked Questions
What's the difference between low-income housing and Section 8?
Low-income housing is a unit with capped, income-based rent. Section 8 is a voucher that helps a tenant pay rent in a home they choose.
What is the most Section 8 will pay for housing?
The limit is the payment standard, set as a share of the area's Fair Market Rent. The voucher covers rent above the tenant's roughly 30% income contribution, up to that cap.
What is the eligible basis in LIHTC?
Eligible basis is the portion of development cost that qualifies for credits, mainly construction and rehab costs, not land.
What are LIHTC / Section 42 income limits?
Households generally must earn no more than 50% to 60% of Area Median Income, depending on the property's set-aside election.
Do income limits vary by ZIP code?
Yes. HUD publishes AMI-based limits each year by area, so the dollar figure for the same AMI percentage differs by location.
Is Section 42 subsidized housing?
It is financed through federal tax credits rather than direct rental subsidy. The savings are built into the rent, not paid to the landlord monthly.
How do I apply for or qualify for Section 42 housing?
Apply directly to the LIHTC property's management office. You generally qualify if your income is at or below the property's limit, often 60% of AMI.
Conclusion
The difference between LIHTC and Section 8 housing comes down to one idea. LIHTC subsidizes the property, and Section 8 subsidizes the tenant.
LIHTC builds affordable units by rewarding developers with tax credits. Section 8 helps renters afford homes through vouchers tied to their income. One grows supply, the other expands access, and together they cover more ground than either could alone.
Whether you are building, investing, or managing affordable housing, knowing how these programs fit is the first step toward a stronger deal. Shamrock Development is here when you are ready to put them to work.
