Before I review our first quarter results for 2023 and our outlook for the second quarter and full year 2023, I would like to remind everyone that my comments related to certain financial measures will be on a non-GAAP basis. We delivered very strong results this quarter, with revenue of $451.6 million, up 27.8% compared to the prior year period. Our GAAP net income for the first quarter was $119.3 million or $2.06 per diluted share, up 29.8% compared to the prior year period based on approximately 58 million shares. Adjusted EBITDA was $220.5 million in the first quarter of 2023 or 48.8% of total revenues compared to $170.1 million in the first quarter of 2022 or 48.1% of total revenues. Non-GAAP net income for the first quarter of 2023 was $142.7 million or $2.46 per diluted share, up 28.9% from the prior year period.
Our revenue growth was driven by strong demand, new business wins and new product adoption. Within total revenues, recurring revenue was $444.4 million for the first quarter of 2023, representing 98.4% of total revenues for the quarter and growing 27.6% from the comparable prior year period.
Adjusted sales and marketing expense for the first quarter of 2023 was $98.1 million or 21.7% of revenues. We have been aggressively investing in marketing to drive strong demo leads that complement our outside sales model.
Adjusted R&D expense was $37.4 million in the first quarter of 2023 or 8.3% of total revenues. Adjusted total R&D costs, including the capitalized portion, were $55.2 million in the first quarter of 2023 compared to $42.9 million in the prior year period, reflecting continued investment in new products.
For Q2 and full year 2023, we anticipate our effective income tax rate to be approximately 28% on a GAAP basis and approximately 26.5% on a non-GAAP basis.
Turning to the balance sheet. We ended the quarter with a very strong balance sheet, including cash and cash equivalents of $506 million and total debt of $29 million. Cash from operations was $146.1 million in the first quarter, representing an increase of 24.6%. The average daily balance of funds held on behalf of clients was approximately $2.4 billion in the first quarter of 2023, up approximately 10% year-over-year.
Now let me turn to guidance. For fiscal 2023, we are raising our outlook and now expect revenue in the range of $1.713 billion to $1.715 billion or approximately 25% year-over-year growth at the midpoint of the range. We expect adjusted EBITDA in the range of $717 million to $719 million, representing an adjusted EBITDA margin of approximately 42% at the midpoint of the range. With these strong results and outlook, we are well-positioned to exceed the Rule of 65.
For the second quarter of 2023, we expect total revenues in the range of $397 million to $399 million, representing a growth rate over the comparable prior year period of approximately 26% at the midpoint of the range. We expect adjusted EBITDA for the first quarter in the range of $152 million to $154 million, representing an adjusted EBITDA margin of approximately 38% at the midpoint of the range.
Finally, after 25 years of rapidly growing Paycom into a highly profitable Company, we're expanding our capital allocation strategy. On May 1, the Board of Directors approved a quarterly dividend program that we expect to initiate in mid-May. In 2023, we project Paycom will generate greater than $1.7 billion in revenues, over $700 million in adjusted EBITDA and strong operating cash flow, all of which continue to grow. We believe Paycom is in a unique position to return value to stockholders in the form of a dividend and still have the necessary resources to aggressively pursue growth opportunities.
Since 2016, we returned a total of nearly $600 million to stockholders through stock buybacks, and we have a $1.1 billion buyback authorization still in place. Today's dividend policy announcement reflects our confidence and the resilience of our long-term growth opportunity, the strength of our balance sheet and the profitability of our business model. We intend to pay a dividend at an annual rate of $1.50 per share with a first quarterly dividend of $0.375 per share payable in mid-June, subject to Board approval.
2023 is off to a great start. We are in a strong financial and strong competitive position in a large and attractive addressable market, and we have a long runway to continue to deliver rapid organic revenue growth, high profit margins and attractive cash flows.
With that, we will open the line for questions. Operator?
