You cannot make deposits into your 403(b) account after retirement. Employee deferrals into the 403(b) account can only be made by earnings from employment with the Plan Sponsor. You can only contribute up to 100 % of your compensation. Compensation may include wages, vacation payouts, sick leave payouts or any income that you would have been entitled to if you continued to work for your employer. Employee deferrals may not be made to the account later than 2 ½ months or the end of the tax year after severance from employment whichever comes first. You cannot contribute employee deferrals from early retirement incentives as a retirement incentive is not compensation for services and you would not be entitled to the incentive if you continued to work.
Employer contributions can continue to be made to the 403(b) account for up to 5 years after your severance from employment.
Although you cannot make employee deferrals into the account you may be able to make transfers or exchanges into your 403(b) account from another eligible retirement account, after severance from employment if the plan allows for it.
