Step-by-step explanation:
In 2021, if Tom has determined that a simplified employee pension (SEP) plan is the best fit for his business, the correct statement regarding implementing the SEP plan is that Tom may contribute up to 25% of his net earnings, not to exceed $58,000, for the year. SEP plans are a type of defined contribution plan favorable for small businesses, including those operated by individual self-employed consultants, due to their simplicity and flexibility. Unlike traditional pensions, these tax-deferred savings vehicles allow for a fixed contribution from the employer to the worker's retirement account and are portable across different employers, which can protect against inflation costs.
