19 related losses in the second quarter. The decrease in noninterest income for the current quarter compared to the same period in 2019 was primarily due to a $513,000 decrease in gain on sale of loans, as discussed above.
Noninterest expense for the third quarter of 2020 increased $620,000, or 4.6%, to $14.2 million compared to $13.5 million for the previous quarter and increased $2.5 million, or 21.4%, compared to $11.7 million for the same quarter in 2019. Noninterest expense for the third quarter of 2020 increased compared to the previous quarter due primarily to increases of $230,000 in salary and employee benefits, $223,000 in other noninterest expenses, consisting primarily of higher office expenses related to implementing COVID-19 safety measures and a return to normal FDIC assessment expense as all of the Bank’s remaining FDIC small bank credits were utilized in the second quarter 2020, and $192,000 in data processing expenses, partially offset by a decrease of $25,000 in occupancy and equipment expenses. The increase in noninterest expense for the third quarter of 2020 compared to the third quarter of 2019 reflecting increased costs primarily due to the growth in our operations resulting from both our acquisitions and organic growth.
The provision for income taxes decreased $64,000 to $1.1 million for the third quarter of 2020, compared to the second quarter of 2020, and decreased $1.1 million compared to $2.2 million for the third quarter of 2019. The decrease in income tax provision in the third quarter of 2020 compared to the prior quarter was primarily due to a decrease in the effective tax rate and a decrease compared to the same quarter in 2019 due to a decline in taxable income. The effective tax rate for the third quarter of 2020 was 25.9% compared to 27.8% for the second quarter of 2020 and 28.0% for the same quarter a year ago. The effective tax rate was lower in the third quarter of 2020 primarily as a result of a higher proportion of favorable permanent adjustments relative to taxable income.
Loans and Credit Quality
Loans, net of deferred fees, totaled $1.7 billion at September 30, 2020, compared to $1.7 billion at June 30, 2020 and $1.2 billion at September 30, 2019, primarily due to our GMB and TIG acquisitions. New loan originations for the quarter ended September 30, 2020 totaled $60.5 million, compared to $161.3 million during the second quarter of 2020 and $93.5 million during the third quarter of 2019. New loan originations in the third quarter of 2020, were concentrated in California with the majority focused in the Los Angeles, Central Coast and San Francisco Bay areas.
Nonaccrual loans totaled $7.6 million or 0.45% of total loans at September 30, 2020, compared to $8.2 million or 0.48% of total loans at June 30, 2020, and $6.6 million or 0.54% of total loans at September 30, 2019. At September 30, 2020, nonaccrual loans guaranteed by government agencies were $871,000, compared to $1.2 million at June 2020 and $3.0 million at September 30, 2019. There were no accruing loans past due more than 90 days at both September 30, 2020 and June 30, 2020, compared to $264,000 at September 30, 2019. Accruing loans past due between 30 and 89 days at September 30, 2020, were $1.2 million as compared to $1.0 million at June 30, 2020, and $3.4 million at September 30, 2019.
At September 30, 2020, the Company’s allowance for loan losses was $15.8 million, or 0.93% of total loans, compared to $13.5 million, or 0.78% of total loans, at June 30, 2020, and $6.4 million, or 0.52% of loans outstanding, at September 30, 2019. In accordance with acquisition accounting, loans acquired from acquisitions were recorded at their estimated fair value, which resulted in a net discount to the loans contractual amounts. Credit discounts are included in the determination of fair value and as a result, no allowance for loan losses is recorded for acquired loans at the acquisition date. However, the allowance for loan loss includes an estimate for credit deterioration of acquired loans that occurs after the date of acquisition, which is included in the loan loss provision in the period that the deterioration occurred. Although the discount recorded on the acquired loans is not reflected in the allowance for loan losses, or related allowance coverage ratios, we believe it should be considered when comparing the current ratios to similar ratios in periods prior to the recent acquisitions. As of September 30, 2020, acquired loans, net of their discounts, totaled $240.0 million and the remaining net discount on these acquired loans was $4.1 million, compared to $355.1 million of acquired loans and $4.9 million of net discounts at June 30, 2020, and $566.1 million of acquired loans and $8.0 million of net discounts at September 30, 2019. The provision for loan losses recorded in the third quarter of 2020 totaled $2.3 million compared to the prior quarter provision of $4.4 million and $479,000 for the same quarter last year. The provision for loan losses includes a provision related to the migration of acquired loans out of the discounted acquired loan portfolio and gives consideration of probable credit losses due to changes in economic conditions driven by the impact of COVID-19 on the U.S. and global economies.
