Tax Environment in Colorado
Colorado has a flat income tax rate of 4.4% in 2025 (reduced from 4.55% in 2024 and 4.63% previously). Colorado's TABOR amendment limits government revenue growth, resulting in periodic taxpayer refunds when revenue exceeds limits. The state offers a generous standard deduction matching the federal amount.
Tip: Colorado's flat rate has been gradually declining through TABOR-related adjustments. The state standard deduction matches the federal ($15,750 single), keeping effective rates low. TABOR refunds provide an additional tax benefit in years when state revenue exceeds limits.

What to know at this income level
Between $45,000 and $80,000, most of your taxable income falls in the 12% bracket with some crossing into the 22% bracket at $48,475 (single, after standard deduction starts around $64,000 gross). This is the income range where the US median household income sits (~$80,000 in 2024), so you are in the mainstream of American earners. Tax-advantaged retirement accounts — 401(k) and IRA — become your most effective tax planning tools.
22% bracket threshold
The 22% bracket starts at $48,475 of taxable income (about $64,000 gross salary for single filers). Each dollar above this threshold costs 10 cents more in tax than the 12% bracket below it. Contributing to a pre-tax 401(k) can keep more income in the 12% bracket. Use calculator →
Pre-tax 401(k) strategy
At the 22% bracket, every $1,000 contributed to a pre-tax 401(k) saves $220 in federal tax immediately. The 2025 limit is $23,500. If you cannot max it out, aim for at least the employer match — typically 3-6% of salary. Use calculator →
Roth vs Traditional IRA
At the 12-22% bracket range, a Roth IRA may be optimal. You pay tax now at a relatively low rate and withdraw tax-free in retirement when you may be in a higher bracket. The 2025 IRA contribution limit is $7,000 ($8,000 if age 50+). Use calculator →
Typical roles at this level: Mid-level office and administrative workers, skilled trades, teachers, police officers, retail managers, and early-career professionals in most fields.
