Notes: This table presents the summary statistics for all observations in 2000–2015. Panel A presents the statistics for the entire sample. See Table A1 in Appendix for Panel B (restricted to corporate groups). CASH ETR is cash taxes paid divided by earnings before taxes. MNE is an indicator variable equal to 1 if the firm is a multinational enterprise and 0 otherwise. NOL = Total net operating losses. ΔNOL = net operating losses utilized to reduce taxable income.

1 Variable scaled by total assets.

2 Variable scaled by sales.

Figure 2:

Evolution of CASH ETR quantiles 0.1, 0.25, 0.5, 0.75, and 0.9 separately for MNEs and domestics.

Notes: The figure plots ETR quantiles 0.1, 0.25, 0.5, 0.75, and 0.9 against the sample years 2000–2015 using the main data source, YRTTI tax return data. The dashed line represents the Finnish statutory corporate income tax rate. Finnish MNEs include Finnish-headquartered multinationals. Foreign MNEs include subsidiaries of foreign-headquartered multinationals that are located in Finland. Domestic groups include purely domestic corporate groups and domestic firms include domestic standalone firms.

Figure 3:

Yearly share of firms with CASH ETR above and below the statutory tax rate for MNEs and domestics.

Notes: YRTTI data, full sample. Left panel figure (MNE) includes Finnish-headquartered multinationals and Finnish subsidiaries of foreign-headquartered multinationals. Right panel figure (Domestic) includes domestic corporate groups and domestic standalone firms. ETR=STR includes firms with an ETR within ±0.01% of the STR.

Figure 4:

Distributions of the difference between CASH ETR and statutory tax rate (STR) in 2000 and 2015.

Notes: YRTTI data, full sample for years 2000 and 2015. The distribution is winsorized from right at 0.2 to increase readability, that is, all values above 0.2 are set to 0.2. The distribution of values above 0.2 is flat with a very low density.

[i] Notes: This table presents the results of estimating equation 1 with an ordinary least squares specification with different sample restrictions. The estimation sample is the entire sample from YRTTI tax return data, but columns 5 to 8 are restricted to corporate groups. Additionally, column 1 (5) restricts the sample to firms (corporate groups) that are observed in each sample year (whether the observation is kept in the final sample or not). Column 2 (6) additionally requires that the firm (corporate group) never reports negative accounting profits. Column 3 (7) requires never utilizing loss carryforwards, and column 4 (8) requires never having outstanding loss carryforwards. Trend is the linear time trend, defined as the tax year less of 2000, the first sample year. Thus, Trend receives values 0–15. All other variables are as defined in Section 4.2. tstatistics are in parentheses.

[ii] *,**, and *** denote significance at the 10%, 5%, and 1% levels, respectively.

Figure 5:

Trend coefficients over the CASH ETR distribution for different sub-samples.

Notes: The figures plot the coefficient point estimates of Trend for every quantile of the CASH ETR distribution for the four different firm types. The shaded blue area describes the 95% confidence interval of the point estimates. The used data is the YRTTI tax return data for 2000–2015. Finnish MNEs include Finnish-headquartered multinationals. Foreign MNEs include subsidiaries of foreign-headquartered multinationals that are located in Finland. Domestic groups include purely domestic corporate groups and domestic firms include domestic standalone firms.

[i] Notes: This table presents the results of estimating equation 1 with an ordinary least squares specification with different sample restrictions. Columns 1 and 2 include only Finnish-owned multinationals, columns 3 and 4 include only subsidiaries of foreign owned MNEs located in Finland, columns 5 and 6 include only domestic corporate groups and columns 7 and 8 include only domestic standalone firms. Trend is the linear time trend, defined as the tax year less of 2000, the first sample I(2013–2015) year. Trend receives values 0–15. Post GFC is an indicator which gets the value 1 after the year 2007. I(2009–2010) and I(2013–2015) are indicators which get the value 1 during years 2009–2010 and 2013–2015. Other variables are as defined in Section 4.2. Coefficients for the control variables are omitted here, see Appendix Table A9 for entire regression output. t statistics are in parentheses.

[ii] *,**, and *** denote significance at the 10%, 5%, and 1% levels, respectively.

Figure 6:

Share of firms reporting zero profit by year.

Notes: The figure illustrates the evolution of firms reporting zero taxable profit and zero accounting profit. The used data source is the YRTTI tax return data for 2007–2015. Firm is considered as reporting zero profit if the taxable (accounting) profit to total assets share of the firm falls between −0.5 and 0.5 percent. Haven affiliated MNEs include Finnish-headquartered multinationals with at least one affiliate located in a tax haven country defined by Menkhoff & Miethe (2019). Non-haven affiliated MNEs include Finnish-headquartered multinationals with no affiliates in tax haven countries. Foreign MNEs include subsidiaries of foreign-headquartered multinationals that are located in Finland. Domestic groups include purely domestic corporate groups and domestic firms include domestic standalone firms. Accounting profit includes all firms due to the share being very similar across the different groups of firms.

Figure 7:

Histograms of ROA and the ratio of taxable profits to total assets.

Notes: The histograms illustrate the distribution of observations around zero return on assets (ROA) and the ratio of taxable profits to total assets. The top panel figures use all observations whereas the bottom panel figures discard observations with any deducted losses. Left panel figures show the histograms of ROA and right panel figures of taxable profits to total assets. The data source is the YRTTI tax return data for 2007–2015. Haven affiliated MNEs include Finnish-headquartered multinationals with at least one affiliate located in a tax haven country defined by Menkhoff & Miethe (2019). Non-haven affiliated MNEs include Finnish-headquartered multinationals with no affiliates in tax haven countries. Foreign MNEs include subsidiaries of foreign-headquartered multinationals that are located in Finland. Domestic groups include purely domestic corporate groups and domestic firms include domestic standalone firms.

Figure A1:

The yearly share of loss-making firms (i.e.,negative accounting profits).

Notes: The data source is the YRTTI tax return data for 2000–2015. MNE includes Finnish-headquartered multinationals as well as subsidiaries of foreign-headquartered multinationals that are located in Finland. Domestic includes domestic corporate groups and domestic standalone firms.

Notes: This table presents the summary statistics for corporate groups in 2000–2015. Panel A with the entire sample is presented in Table 1. CASH ETR is cash taxes paid divided by earnings before taxes. MNE is an indicator variable equal to 1 if the firm is a multinational enterprise and 0 otherwise. NOL = Total net operating losses. △NOL = net operating losses utilized to reduce taxable income.

1 Variable scaled by total assets.

2 Variable scaled by sales.

Column 1 includes all firms, column 2 includes only Finnish-owned multinationals, column 3 includes only subsidiaries of foreign owned MNEs located in Finland, column 4 includes only domestic corporate groups, and column 5 includes only domestic standalone firms. Trend is the linear time trend, defined as the tax year less of 2000, the first sample year. Thus, Trend receives values 0–15. All other variables are as defined in Section 4.2. The estimation sample is the entire sample from YRTTI tax return data. t statistics are in parentheses.

[i] Notes: This table presents the results of estimating equation 1 with an ordinary least squares specification with different foreign affiliate controls. The sample is multinational firms for years 2007–2015. Column 1 shows the baseline result without additional controls. Columns 2 to 5 alter the set of included foreign affiliate controls. HasTaxHaven is an indicator variable which receives value one when the firm has at least one affiliate located in a tax haven country, defined according to Menkhoff & Miethe (2019). Number of tax haven subsidiaries is the observed absolute number of tax haven subsidiaries of the firm. Sales (Employees) of the subsidiaries is the aggregated sales (employees) of the foreign subsidiaries of the firm. Other variables are as defined in Section 4.2. t statistics are in parentheses.

[ii] *, **, and *** denote significance at the 10%, 5%, and 1% levels, respectively.
