I make about 19k a year on disability. I also receive land rent of 4k. Can I make anymore without filing taxes.

You may have to file tax return without making anymore.

You must report as income any amount you receive for your disability through an accident or health insurance plan paid for by your employer:
•If both you and your employer have paid the premiums for the plan, only the amount you receive for your disability that is due to your employer’s payments is reported as income.
•If you pay the entire cost of a health or accident insurance plan, do not include any amounts you receive for your disability as income on your tax return.

The $4,000 is over the personal exemption amount, so you may have to file regardless of whether the disability is taxable or not.

If the disability is tax-exempt for the reason specified by MukatA, you will owe NO tax, but you probably still have to file.
