@alienghic @CMDoran Several such groups exist! And there’s a spectrum to tax avoidance, of course - fully voluntary civil disobedience/ illegal nonpayment, voluntary reduction of income below the standard deduction (or for the wealthy, tax-efficient investment, possibly taking a few weeks or years of unpaid vacation or sabbatical), avoiding consumption taxes on levied goods / sumptuary law by eschewing e.g. alcohol and tobacco (or DIYing them, legality of which varies by jurisdiction), avoidance of tariffs paid to our own government on goods from targeted nations by choosing other sources or skipping purchases altogether until such time as tariffs are repealed, nonmonetary exchanges and redistribution such as trading babysitting for prepared meals with a neighbor, carpooling, holding clothing or home goods swap meets, community gardening, repair cafes, mutual aid giving, even charitable gifts are more straightforward as a deduction on the lower end of incomes this year. Frugality *in general,* because all tax boils down to a percentage of revenue dollars - buying fewer goods, at lower prices, and postponing what isn’t essential. Literally just using the library, instead of purchasing things from companies which then must pay tax on revenue. Rejecting corporate surveillance and ad revenue transactions via careful selection of our social media (at least this one we’re all doing at least some of the time, here on fedi.)
Any kind of economic slowdown or reduced participation in the monetary economy helps, and this would be a great time to combine it with targeted boycotts as well as general Opt Out/ Blackout/ Buy Nothing Rebellion social movements; personally I also like the #SpendingStrike framing as US folks are so often referred to as consumers rather even than citizens. Also a great time for people to save up in case of work stoppages, union strikes, etc. affecting their own jobs or others in their communities they may wish to have the financial latitude to support.
Then there’s finding a financial institution, such as a credit union, which ideally isn’t turning around and investing that savings from deferred or abstained consumption into “defense” or other lobby industries such as fossil fuels, and is hopefully beneficial to the local economy, choosing co-op and locally-run businesses for obligatory consumption to bolster local resilience, etc.
And, of course, aggressive engagement with local elections, since that rapidly starts determining the outcomes of much more money than most of us personally have control over.
