Money Purchase Pension Plans
Money Purchase Pension Plans are a type of plan that requires a specific contribution formula from the employer.
Unlike profit sharing plans, where employer contributions are often discretionary, money purchase pension plans are more structured and require a set contribution amount.
The contribution deadline for minimum funding purposes is 8½ months after the end of the plan year, which can be a tight deadline for employers to meet.
If the deadline is not met, the employer is subject to a late funding penalty, which can be costly.

Employers with a fiscal year that matches the plan year may be able to deduct payments necessary to fully fund the plan within the allowable funding period, thanks to a matching tax return deadline.
However, the 8½ month funding period remains the same regardless of whether or not the employer files for an extension.

Top Heavy
A plan is considered top heavy if at least 60% of the benefits belong to key employees. This means that non-key employees don't get to enjoy the same benefits as their colleagues.
To correct this imbalance, top heavy plans must provide minimum contributions to non-key employees, usually 3% of their compensation. These contributions must be paid by the last day of the following plan year.
The timing of top heavy contributions is similar to matching contributions, which means you need to plan ahead to avoid any issues.
