When the tenant has misrepresented the facts upon which the tenant rent is based, or has failed to furnish timely required income verifications to DCHA without good cause approved by DCHA, to the extent that the amount of tenant rent charged is less than it should have been, DCHA shall assess the tenant a retroactive rent charge.
The amount of the retroactive charge shall be the additional amount of tenant rent the tenant would have been charged if there had not been misrepresentation, or failure to furnish income verification, by the tenant.
If it is found at the time of recertification that the tenant failed to report changes in annual income as they occurred, and the changes would have required a higher tenant rent, the increased rent shall be made retroactive to the date the rent would have increased had the tenant made the report.
