How Low Income Housing Tax Credit Apartments Work

Low Income Housing Tax Credit apartments are rental homes that were built or renovated with the help of a federal tax incentive. In exchange for that incentive, the property owner agrees to rent specific units at below-market rates to households earning under a set income limit. The result is privately owned housing that stays affordable for years, often for decades.

This guide explains where the funding comes from, how income and rent limits are calculated, who typically qualifies, and what the application process looks like from start to finish.

What Are Low Income Housing Tax Credit Apartments?

A Low Income Housing Tax Credit (often shortened to LIHTC and pronounced lie-tech) is a federal tax incentive created in the 1980s to encourage private investment in affordable rental housing. Rather than paying a landlord directly, the government gives tax credits to the people who build and own the property.

In return, the owner must follow two main rules for a set period of time:

• Keep a certain number of units affordable to households below specific income limits.
• Charge rent that stays at or below a maximum allowed amount for those units.

The important takeaway is that these apartments are not public housing and are not government-run. They are ordinary rental buildings owned by private companies, developers, or nonprofit organizations.

Where the Funding Comes From

The program works through a chain of steps:

1. Each year, the federal government issues a limited amount of tax credits to each state, based on population.
2. State housing agencies award those credits to developers through a competitive review process.
3. The developer sells the credits to investors, who receive them in exchange for funding the project.
4. The cash raised this way reduces the amount the developer needs to borrow.
5. Because the debt is smaller, the property can charge lower rents and still cover its costs.

In short, the subsidy is attached to the building, not to the tenant. That is a key difference from voucher-style rental assistance.

The Two Main Types of Tax Credits

Developers generally work with one of two credit types, and the difference affects how a project is financed.

Competitive credits

These are awarded through an application process and are typically used for new construction or major renovations. They cover a larger share of a project’s eligible costs, which is why they are highly sought after.

Bond-related credits

These are paired with tax-exempt bond financing and cover a smaller share of eligible costs. Because they are not as limited in supply, they are often used for projects that need a faster or more predictable funding path.

How Income Limits Are Worked Out

Income limits for these apartments are based on the area median income, usually called AMI. That figure is calculated for a metro area or county and then adjusted for household size.

Most LIHTC units target households earning at or below one of these tiers:

• 30% of AMI — extremely low income
• 50% of AMI — very low income
• 60% of AMI — low income, the most common target
• 80% of AMI — moderate income, used in some projects

A household’s income is compared to the limit for its size. For example, a four-person household has a higher income limit than a one-person household in the same area.

How Rent Limits Are Set

Rent limits are tied to the same income figures. In general, the maximum rent for a unit is about 30% of the income limit for the household size expected to live there, then adjusted downward for any utilities the tenant pays directly.

Two details often surprise renters:

• The rent limit is not based on your personal income. Two neighbors in identical units may pay the same rent even if one earns noticeably more.
• Utility costs matter. If you pay for heat, electricity, or water, an allowance is subtracted from the rent cap, so your rent may be lower than the published limit.

Who Qualifies for a Tax Credit Apartment?

Qualifying is based mainly on household income at the time you apply and move in. Common requirements include:

• Total household income below the limit for the unit size
• A completed application with proof of income, such as pay stubs, benefit letters, or tax records
• Standard rental screening, including background and credit checks
• Meeting any property-specific rules, such as occupancy standards

Because demand usually exceeds supply, many properties maintain waiting lists. Being eligible does not guarantee an available unit.

How to Apply for a LIHTC Apartment

If you want to apply, a practical approach looks like this:

1. Identify local options. Search for affordable housing listings or contact a local housing counseling service for a current list of tax credit properties.
2. Contact properties directly. Call or visit the leasing office to ask whether they have tax credit units and whether the waiting list is open.
3. Ask about the income tier. Confirm which income limit applies, since this determines whether you qualify.
4. Gather documents. Collect identification, income verification, and recent bank statements before you apply.
5. Submit the application and join the list. Ask how the list is ordered and how often it is updated.
6. Follow up periodically. Check in every few months to confirm your place and update your contact details.

What Happens After You Move In

Once you are a resident, the property must verify your household income at least once a year. This is how the owner proves compliance with the program.

If your income rises above the limit later on, you are usually not asked to move out. Rules vary by property and program agreement, but in many cases the household can stay, sometimes with a rent adjustment, and the unit may simply count differently in the owner’s required affordable total.

How It Compares to Other Rental Assistance

It helps to separate tax credit housing from other types of help:

• Tax credit apartments: The subsidy is tied to the building. You apply to the property, and the unit stays affordable for a required period, often 30 years or longer.
• Voucher programs: The subsidy follows the renter. You receive a voucher and use it to help pay rent at a participating landlord’s property.
• Public housing: The property is owned and operated by a public housing authority.

Common Misconceptions

Myth: All units in the building are affordable. Many tax credit developments include a mix of affordable and market-rate units. Only the designated units carry the income and rent limits.

Myth: The apartments are free or nearly free. Tenants pay rent. It is simply capped below what the open market would charge.

Myth: You can be removed once your income improves. Rising income rarely triggers an immediate move-out, though it may affect how the unit is counted.

Myth: The housing looks like a government building. Because the funding model relies on private investment, these properties are generally standard apartment communities.

The Bottom Line

Low Income Housing Tax Credit apartments exist because private developers receive a tax benefit in exchange for keeping rents affordable for a long stretch of time. The subsidy sits with the building, so renters apply directly to the property, must fall under an area income limit, and pay rent that is capped based on local median income. Waiting lists are common, so applying early to several properties and keeping your documents ready gives you the best chance of securing a unit.
