Social Security Disability Insurance (SSDI) and the Supplemental Nutrition Assistance Program (SNAP) both use income rules to determine who can receive benefits, but they count income in very different ways. Understanding these differences is important because you could have too much income for one program but still receive support from another.

SSDI is a program run by the Social Security Administration that provides monthly cash payments to people with disabilities who have paid into the Social Security system through payroll taxes. When Social Security reviews your income for SSDI, they look at your "countable income." This is not the same as your gross income or what you report on your tax return. SSDI has specific rules about what counts and what doesn't count.
SNAP, which used to be called food stamps, is administered by the U.S. Department of Agriculture and provides monthly benefits that you can use to buy food. The income limits for SNAP are generally much lower than for SSDI. However, SNAP also has its own system for counting income that differs from SSDI's rules.
For example, suppose you earn $1,200 per month from part-time work. Under SSDI rules, you would exclude the first $65 of earnings plus half of the remaining amount. That means only about $568 would count as income. Under SNAP rules, though, most of that $1,200 would count, though SNAP allows a 20% deduction from gross income before calculating your benefit amount.
The key takeaway: Just because you don't meet the income limit for one program doesn't mean you won't meet it for another. Both SSDI and SNAP have separate income thresholds. Learning how each program counts what you earn, receive from family, or get from other sources can help you understand what you might receive from each one.
SSDI has a detailed list of what is considered "countable income" for the purpose of determining ongoing benefits. When you first apply for SSDI, your income doesn't affect your decision to receive benefits—Social Security looks only at whether you have a disability and your work history. However, once you're receiving SSDI, your income can affect how much you receive, especially if you're working.

Earned income is money you make from working. This includes wages from a job, self-employment income, and any payments you receive for services you provide. If you're self-employed, Social Security counts your net profit (income minus business expenses) as earned income. This is one of the main types of income that affects SSDI payments.
Here's how SSDI counts your work earnings each month: The first $65 of what you earn is not counted. Then, for every dollar you earn above $65, only 50 cents counts toward your income. This is called the "earned income exclusion." For example, if you earn $300 in a month, $65 is excluded, leaving $235. Half of $235 is $117.50, which is your countable income. The other $117.50 doesn't count at all.
Unearned income includes Social Security retirement or survivor benefits, pensions, interest from bank accounts, rental income, and support payments from family members. Most unearned income counts dollar-for-dollar. If someone gives you $200 as a gift, the first $20 per month is excluded, but the rest counts as income.
What doesn't count as income for SSDI includes the value of food, clothing, or shelter provided by others; certain amounts of in-kind support and maintenance; food stamps; housing subsidies; and certain infrequent or irregular income under $30 per month. Also, if you're a student, earnings from part-time work (up to certain limits) may not count.
Practical takeaway: If you receive SSDI and are thinking about working, calculate your countable income using the $65 exclusion and 50% rule to understand how much of your earnings will reduce your monthly SSDI check. Keep records of your work expenses if you're self-employed, because these reduce what counts as income.
SNAP uses a simpler income-counting system than SSDI, but it has lower income limits overall. Most types of income—earned and unearned—count toward your SNAP income limit. SNAP looks at your household's total monthly income before certain deductions are applied.

Earned income under SNAP includes money from working at a job, whether you're employed by someone else or self-employed. This is counted at its full gross amount, meaning you report the total before taxes, union dues, or other deductions are taken out. If you're self-employed, you report your gross income, not your net profit.
Unearned income counts as well. This includes Social Security benefits (all types), pensions, unemployment benefits, child support, spousal support, and cash assistance from other government programs. If a family member gives you money or support, it may count depending on the situation. In most cases, cash payments or money transfers count toward your income.
SNAP allows certain income exclusions before determining whether you're within the income limit. These exclusions include the first $20 of unearned income per month, which is excluded entirely. Additionally, if anyone in your household is earning income, 20% of all earned income is deducted. This 20% deduction applies before other calculations. For example, if your household has $1,500 in earned income, $300 (20%) is excluded, leaving $1,200 to count.
Some income does not count toward SNAP at all. This includes federal income tax refunds and certain payments like Supplemental Security Income (SSI) in most cases, certain education benefits, the value of food stamps themselves, and income earned by a household member who is a full-time student working part-time under certain conditions.
Current SNAP income limits (as of 2024) are based on household size. For a single person, the gross monthly income limit is around $1,550, though this adjusts yearly. For a family of four, it's around $3,180. However, most people receive SNAP only if their net income—after deductions—is below 100% of the federal poverty line.
Practical takeaway: When calculating whether you might meet SNAP income rules, start with your household's total gross income, subtract the $20 unearned income exclusion, subtract 20% of earned income, and then check this against current limits. Income limits change each October, so verify the current year's numbers through your state's SNAP office or official USDA resources.
Beyond income, both SSDI and SNAP have rules about assets or "resources"—money and possessions you own. However, the two programs treat resources very differently, which is another reason why someone could be approved for one program but not the other.

SNAP has strict resource limits that are quite low. For most households, the limit is $2,500 in countable resources. For households where someone is age 60 or older, or someone has a disability, the limit is $3,750. Resources include cash, money in bank accounts, stocks, bonds, and vehicles (with some exceptions). However, certain resources don't count. Your primary home and the land it sits on are not counted. One vehicle per household member is excluded if it's used for work, going to school, or going to medical appointments. Retirement accounts like 401(k)s and IRAs are usually not counted.
SSDI, on the other hand, does not have resource limits at all. This is a major difference. You could have $100,000 in a bank account and still receive your full SSDI benefit. This is because SSDI is based on your work history and disability status, not on your financial need. Your resources do not affect whether you receive SSDI or how much you receive.
This difference creates an important opportunity. Someone who doesn't meet SNAP's resource limit might still meet the income rules for SNAP if they can reduce their countable resources. However, this requires careful planning, as simply spending down resources can be counted as income in some programs or may have tax consequences.
There is a related program to SSDI called Supplemental Security Income (SSI) that does have both income and resource limits. SSI is for people with disabilities who don't have enough
