The Employee Retention Credit (“ERC”), as originally enacted on March 27, 2020, by the CARES Act, is a refundable tax credit against certain employment taxes equal to 50% of the qualified wages an eligible employer pays to employees after March 12, 2020, and before January 1, 2021. The Taxpayer Certainty and Disaster Tax Relief Act (the “Relief Act”), enacted on December 27, 2020, amended, and extended the ERC. On March 1, 2021, the IRS released Notice 2021-20 to provide guidance on the original ERC, as modified by the Relief Act. During 2021 we filed Form 941-X to claim a credit of $105,000 on qualified wages paid in 2020. This receivable appears on the balance sheet as of December 31, 2021, as Tax Receivable, and as a credit to wages in the Statement of Operations during the twelve months ended December 31, 2021.
The Relief Act extended and enhanced the ERC for qualified wages paid after December 31, 2020, through June 30, 2021. Under the Relief Act, eligible employers may claim a refundable tax credit against certain employment taxes equal to 70% of the qualified wages an eligible employer pays to employees after December 31, 2020, through June 30, 2021. As of the March 11, 2021, passage of the American Rescue Plan Act, the ERC was available for all four quarters of 2021. However, the Infrastructure Investment and Jobs Act enacted on November 15, 2021, ended the ERC effective September 30, 2021.
During the first quarter of 2021, we experienced a decline in gross receipts of 25% compared to the first quarter of 2019. This decline, along with continued underutilization of certain manufacturing equipment, reduction in employee’s workloads, travel restrictions and supply chain issues, qualified us to receive the ERC. We filed Form 941 for the first quarter of 2021 and claimed a credit of $150,507 on qualified wages paid in the first quarter of 2021. These funds were received during the second quarter of 2021 and appear as a credit to wages in the Statement of Operations during 2021. An employer that has a decline continues to be eligible until the end of the calendar quarter in which gross receipts are greater than 80% of its 2019 calendar quarter receipts. Thus, we were eligible for this credit for the second quarter of 2021 in the amount of $151,701, which appears as a credit to wages in the Statement of Operations for 2021.
During the second quarter of 2021, we experienced a decline in gross receipts of 30% compared to the second quarter of 2019. This decline, along with continued underutilization of certain manufacturing equipment, reduction in employee’s workloads, travel restrictions and supply chain issues, qualified us to receive the ERC for the third quarter of 2021. As previously mentioned, an employer that has a decline in gross receipts continues to be eligible until the end of the calendar quarter in which gross receipts are greater than 80% of its 2019 calendar quarter receipts. As a result, we were eligible for this credit for the third quarter of 2021 in the amount of $153,713, which appears as a credit to wages in the Statement of Operations for 2021.
In addition, the American Rescue Plan Act of 2021 allows eligible employers with fewer than 500 employees to qualify for a tax credit for providing paid time off for each employee receiving COVID-19 vaccinations and for any time needed to recover from the vaccine. The Company received a credit of $11,042 and this amount appears as a credit to wages in the Statement of Operations for 2021.
For the year ended December 31, 2021, we had total revenue of $13,448,021. This was an increase of $2,551,992, or 23.4%, compared to 2020. The increase was primarily due to increased volume and higher raw material pricing. During 2020, total revenue was adversely impacted by lower volume, pricing, and COVID-19 related issues.
Gross profit was $3,529,255 for 2021 compared to $2,198,290 for 2020. The increase was attributable to higher revenue as well as product mix and improved manufacturing efficiency.
Operating expenses were $1,751,349 and $1,681,943 for 2021, and 2020, respectively.
Income from operations was $1,777,906 and $516,347 for 2021 and 2020, respectively, which included $571,962 related to the ERC and ARP credits during 2021.
Consistent with our growth strategy, we have identified niche markets that can benefit from our expertise in custom powder solutions, such as near-infrared doped phosphors and short-wave infrared applications. These applications enable extended life of phosphors for specific nighttime identification needs of defense personnel and first responders.
New initiatives are also being pursued that utilize our vacuum hot press, cold isostatic press, and kilns for increased production and development projects, including diffusion bonding. We recently manufactured and sold conductive metal oxides for direct current sputtering of Tungsten Oxide and Molybdenum Oxide materials. We continue to invest in developing new products for all our markets including specialty bonding processes for Aerospace customers. Those products involve research and development expense to accelerate time to market.
