I was getting that information from va32h's post (#52).
Oops! Sorry if I was unclear.
We get our car/property from insurance from USAA - which is only eligible to those with a connection to the military, and their rates are better than any other company I have researched.
Base pay is taxable, but allotments (such as a housing allowance, if you live off-post) are not. All income earned while the service member is stationed overseas is not taxable. When my husband was deployed we received additional allotments - Hazardous Duty Pay, and Separation pay for me. When he was a recruiter, he also received an additional allotment for that.
Because my husband's official residence is Illinois, which does not charge state income tax to military members, we have never had to pay state income tax, regardless of where we live (although that is moot now, because we live in Texas, which has no state income tax anyway).
The PX is more like a department store; goods there are not really discounted, but we don't have to pay sales tax. Nor do we pay sales tax on gas purchased on base. The commissary is where military members can buy their groceries, and these usually are at quite good discounts, practically at cost, and again no tax, although there is a 4-5% surcharge on commissary purchases, which helps with operating expenses.
And there are lots of other little perks - I already mentioned Shades of Green being $103 per night, year round. Higher ranking members pay more, lower ranks pay less. We can also rent camping equipment and even RVs from the Morale, Welfare and Recreation office. A Class C RV rents for $75 per night!
Most bases have something called billetting, which is an on-base motel, basically. We haven't stayed in billetting for awhile, but rates were $35-$50 per night, and this was for a quite large room, with fridge and microwave.
All the Busch Gardens properties offer free admission for active duty military and up to three family members. Three years ago, Disney had a promotion that gave military 40% off any room, free length of stay passes for the soldier and additional length of stay passes for family members for $99. (yes, we went that year!)
Another thing to consider is the predictability and reliability of your employment, when you are in the military. You aren't going to get laid off, or have yor pay reduced. No matter how insolvent the gov't is, you will get paid (they always pay the people with the guns first, says my husband).Your raises come at a regular, predictable time.
My only complaint regarding pay, and I'm sure Buck Naked will back me up on this, is that it is frustrating when the soldier has to travel, and pay for his own hotel or rental car, and wait ages to get reimbursed. We have had to wait over 60 days to get reimbursed for travel expenses, and it was not easy juggling that. There was also a very bad period when the Defense Finance Accounting Service decided that my husband had retired instead of re-enlisted, and didn't pay him at all for two months! But those did get straightened out, eventually.
