Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes On March 27, 2020 the Coronavirus Aid, Relief and Economic Security Act, or CARES Act, was signed into law. The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. The CARES Act did not have a material impact on the benefit from for income taxes for the year ended December 31, 2021. The following are the domestic and foreign components of our (loss) income before income taxes (in thousands):
| Year Ended December 31,
| 2021 |  | 2020 |  | 2019
Domestic | $ | (119,195) |  |  | $ | 25,272 |  |  | $ | 19,778 |

Total (loss) income before income taxes | $ | (119,615) |  |  | $ | 12,325 |  |  | $ | 10,604 |
The total income before income taxes above includes (loss) income from our equity method investment of $0.3 million for 2019. There was no (loss) income from equity method investments for 2021 and 2020, respectively. The details for the (benefit from) provision for income taxes by jurisdiction are as follows (in thousands):

The tax effects of temporary differences that give rise to significant portions of our deferred tax assets and liabilities consisted of the following as of December 31, 2021 and 2020, (in thousands):
| As of December 31,
| 2021 |  | 2020
Deferred tax assets |  |  |
Deferred revenue | $ | 697 |  |  | $ | 694 |

Total deferred tax assets | 55,715 |  |  | 44,597 |

Net deferred tax assets | 41,545 |  |  | 31,647 |
Deferred tax liabilities |  |  |
Depreciation and amortization | (10,865) |  |  | (6,024) |
State taxes | (3,026) |  |  | (2,816) |
Net deferred tax liabilities | (13,891) |  |  | (8,840) |
Net deferred tax assets and liabilities | $ | 27,654 |  |  | $ | 22,807 |
We evaluated the realizability of net deferred tax assets and determined it is more likely than not that separate state net operating losses, net operating losses from the acquisition of Legalinc, capital loss carryovers from the acquisition of Earth Class Mail, the deferred tax assets for Pulse IP, LLC and Pulse Business, LLC, and foreign deferred tax assets will not be realized based on the available objective evidence and have recorded a valuation allowance on such deferred tax assets. The following table summarizes the valuation allowance:
| Year Ended December 31,
| 2021 |  | 2020 |  | 2019
Beginning balance | $ | 12,950 |  |  | $ | 7,816 |  |  | $ | 7,707 |
Net increase in current year | 1,312 |  |  | 4,646 |  |  | 769 |
Net (decrease) increase in valuation prior period | (14) |  |  | 528 |  |  | (87) |
Net decrease in valuation allowance from acquisitions | (78) |  |  | (40) |  |  | (573) |
Ending balance | $ | 14,170 |  |  | $ | 12,950 |  |  | $ | 7,816 |
Net changes in the valuation allowance in the years ended December 31, 2021, 2020, and 2019 include changes recorded through earnings relating to losses primarily from foreign operations and to a lesser extent valuation allowances established relating to acquired businesses. At December 31, 2021 and 2020, we had federal net operating loss, or NOL, carryforwards of $29.8 million and $11.7 million, respectively, which will begin to expire in 2032. At December 31, 2021, and 2020, we had state NOL carryforwards of $58.8 million and $49.8 million, respectively, which will begin to expire in 2032. At December 31, 2021 and 2020, we had foreign NOL carryforwards of $31.8 million and $32.4 million, respectively, which can be carried forward indefinitely and are not subject to expiration. At December 31, 2021 and 2020, we had federal tax credit carryforwards of $7.6 million and $6.2 million, respectively, which will begin to expire in 2034. At December 31, 2021 and 2020, we had state tax credit carryforwards of $9.6 million and $8.8 million, respectively, which carry forward indefinitely. Our domestic entities may be subject to an annual limitation on the utilization of NOL and credit carryforwards based on changes in ownership as defined by Section 382 of the Internal Revenue Code of 1986. In 2018, we acquired Legalinc and in 2021 we acquired Earth Class Mail. Both were structured as stock acquisitions. Since there was a change in ownership, the acquired NOL carryforwards are subject to an annual Section 382 limitation on the utilization of the NOL carryforwards. We have had foreign operations since 2013. We have not provided for U.S. income taxes on the undistributed earnings and other outside temporary differences of foreign subsidiaries as they are considered indefinitely reinvested outside the U.S. At December 31, 2021, 2020 and 2019, the amount of temporary differences related to undistributed earnings and other outside temporary differences upon which U.S. income taxes are not material to our consolidated financial statements. The following table summarizes the changes in unrecognized tax benefits for the years ended December 31, 2021 and 2020 (in thousands):
| Gross Unrealized Tax Benefits
Balance at Balance at December 31, 2018 | $ | 6,498 |
Additions for tax positions related to the current year | 671 |
Reductions for tax positions related to prior years | (913) |
Balance at December 31, 2019 | $ | 6,256 |
Additions for tax positions related to the current year | 916 |
Additions for tax positions related to prior years | 59 |
Balance at December 31, 2020 | $ | 7,231 |
Additions for tax positions related to the current year | 887 |
Reductions for tax positions related to prior years | (245) |
Balance at December 31, 2021 | $ | 7,873 |
If recognized, $7.9 million of unrecognized tax benefits, excluding interest and penalties, would reduce our annual effective tax rate. Due to the uncertain and complex application of tax laws and regulations, it is possible that the ultimate resolution of uncertain positions may result in liabilities that could be materially different from these estimates. In such an event, we will record additional tax expense or benefit in the period in which resolution occurs. Our policy is to recognize interest and penalties related to income tax matters in income tax expense. At December 31, 2021 and 2020, accrued interest and penalties related to income tax positions were not material to our consolidated financial statements. We do not anticipate that unrecognized tax benefits will materially change within the next twelve months. We are subject to taxation and file income tax returns in the U.S. federal, state, and foreign jurisdictions. The federal income tax return for the years 2018 through 2020 and state income tax returns for the tax years 2008 through 2020 remain open to examination. We are under examination in one state which is not expected to have an impact on our results of operations, cash flows and financial condition.
