Built by Tom Wood — 20+ years in global mobility tax.

Founder

Walka Advisory is Tom Wood’s practice at the intersection of global mobility, tax and data. Tom spent 23 years in global mobility tax at PwC and Vialto Partners — latterly as Tax Director, advising employers from start-ups to FTSE100 multinationals on moving people across borders. The PIT Comparator is the practice’s working reference: four public datasets, distilled into a view of how 104 tax administrations actually register, assess and enforce personal income tax.
